The five biggest threats to our natural world and how we can stop them – The Guardian
The worlds wildlife populations have plummeted by more than two-thirds since 1970 and there are no signs that this downward trend is slowing. The first phase of Cop15 talks in Kunming this week will lay the groundwork for governments to draw up a global agreement next year to halt the loss of nature. If they are to succeed, they will need to tackle what the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) has identified as the five key drivers of biodiversity loss: changes in land and sea use; direct exploitation of natural resources; climate change; pollution; and invasion of alien species.
1
Changes in land and sea use
Its hidden destruction. Were still losing grasslands in the US at a rate of half a million acres a year or more.
Tyler Lark, from the University of Wisconsin-Madison, knows what he is talking about. Lark and a team of researchers used satellite data to map the expansion and abandonment of land across the US and discovered that 4m hectares (10m acres) had been destroyed between 2008 and 2016.
Large swathes of the United States great prairies continue to be converted into cropland, according to the research, to make way for soya bean, corn and wheat farming.
Changes in land and sea use has been identified as the main driver of unprecedented biodiversity and ecosystem change over the past 50 years. Three-quarters of the land-based environment and about 66% of the marine environment have been significantly altered by human actions.
North Americas grasslands often referred to as prairies are a case in point. In the US, about half have been converted since European settlement, and the most fertile land is already being used for agriculture. Areas converted more recently are sub-prime agricultural land with yields 70% lower than the national average, which means a lot of biodiversity is being lost for diminishing returns.
Our findings demonstrate a pervasive pattern of encroachment into areas that are increasingly marginal for production but highly significant for wildlife, Lark and his team wrote in the paper, published in Nature Communications.
Boggier areas of land, or those with uneven terrain, were traditionally left as grassland, but in the past few decades, this marginal land has also been converted. In the US, 88% of cropland expansion takes place on grassland, and much of this is happening in the Great Plains known as Americas breadbasket which used to be the most extensive grassland in the world.
According to the UNs Convention on Biological Diversity there arefive main threatsto biodiversity. In descending order these are: changes in land and sea use; direct exploitation of natural resources; climate change; pollution and invasive species.
1.For terrestrial and freshwater ecosystems, land-use change has had the largest relative negative impact on nature since 1970.More than a third of the worlds land surface and nearly 75% of freshwater resources are now devoted to crop or livestock production.Alongside a doubling of urban area since 1992, things such as wetlands, scrubland and woodlands which wildlife relies on are ironed out from the landscape.
2. The direct exploitation of organisms and non-living materials,including logging, huntingand fishing and the extraction of soils and water are allnegatively affecting ecosystems.In marine environments, overfishing is considered to be the most serious driver of biodiversity loss.One quarter of the worlds commercial fisheries are overexploited, according to a 2005Millennium Ecosystem Assessment.
3. The climate crisis is dismantling ecosystems at every level. Extreme weather events such as tropical storms and flooding are destroyinghabitats.Warmer temperatures are also changing the timing of natural events such as theavailability of insects and when birds hatch their eggs in spring. The distribution of species and their range is also changing.
4. Many types of pollution are increasing. In marine environments, pollution from agricultural runoff (mainlynitrogen and phosphorus)do huge damage to ecosystems. Agricultural runoff causes toxic algal blooms and even"dead zones"in the worst affectedareas.Marine plastic pollution has increased tenfold since 1980,affecting at least 267 species.
5. Since the 17th century, invasive species havecontributed to 40%of all known animal extinctions. Nearly one fifth of the Earths surface is at risk of plant and animal invasions. Invasive species change the composition of ecosystems by outcompeting native species.
Thank you for your feedback.
Hotspots for this expansion have included wildlife-rich grasslands in the prairie pothole region which stretches between Iowa, Dakota, Montana and southern Canada and is home to more than 50% of North American migratory waterfowl, as well as 96 species of songbird. This cropland expansion has wiped out about 138,000 nesting habitats for waterfowl, researchers estimate.
These grasslands are also a rich habitat for the monarch butterfly a flagship species for pollinator conservation and a key indicator of overall insect biodiversity. More than 200m milkweed plants, the caterpillars only food source, were probably destroyed by cropland expansion, making it one of the leading causes for the monarchs national decline.
The extent of conversion of grassland in the US makes it a larger emission source than the destruction of the Brazilian Cerrado, according to research from 2019. About 90% of emissions from grassland conversion comes from carbon lost in the soil, which is released when the grassland is ploughed up.
The rate of clearing that were seeing on these grasslands is on par with things like tropical deforestation, but it often receives far less attention, says Lark.
Food crop production globally has increased by about 300% since 1970, despite the negative environmental impacts.
Reducing food waste and eating less meat would help cut the amount of land needed for farming, while researchers say improved management of existing croplands and utilising what is already farmed as best as possible would reduce further expansion.
Lark concludes: I think theres a huge opportunity to re-envision our landscapes so that theyre not only providing incredible food production but also mitigating climate change and helping reduce the impacts of the biodiversity crisis by increasing habitats on agricultural land.PW

Direct exploitation of natural resources
From hunting, fishing and logging to the extraction of oil, gas, coal and water, humanitys insatiable appetite for the planets resources has devastated large parts of the natural world.
While the impacts of many of these actions can often be seen, unsustainable groundwater extraction could be driving a hidden crisis below our feet, experts have warned, wiping out freshwater biodiversity, threatening global food security and causing rivers to run dry.
Farmers and mining companies are pumping vast underground water stores at an unsustainable rate, according to ecologists and hydrologists. About half the worlds population relies on groundwater for drinking water and it helps sustain 40% of irrigation systems for crops.
The consequences for freshwater ecosystems among the most degraded on the planet are under-researched as studies have focused on the depletion of groundwater for agriculture.
But a growing body of research indicates that pumping the worlds most extracted resource water is causing significant damage to the planets ecosystems. A 2017 study of the Ogallala aquifer an enormous water source underneath eight states in the US Great Plains found that more than half a century of pumping has caused streams to run dry and a collapse in large fish populations. In 2019, another study estimated that by 2050 between 42% and 79% of watersheds that pump groundwater globally could pass ecological tipping points, without better management.
The difficulty with groundwater is that people dont see it and they dont understand the fragility of it, says James Dalton, director of the global water programme at the International Union for Conservation of Nature (IUCN). Groundwater can be the largest and sometimes the sole source in certain types of terrestrial habitats.
Uganda is luxuriantly green, even during the dry season, but thats because a lot of it is irrigated with shallow groundwater for agriculture and the ecosystems are reliant on tapping into it.
According to UPGro (Unlocking the Potential of Groundwater for the Poor), a research programme looking into the management of groundwater in sub-Saharan Africa, 73 of the 98 operational water supply systems in Uganda are dependent on water from below ground. The country shares two transboundary aquifers: the Nile and Lake Victoria basins. At least 592 aquifers are shared across borders around the world.
Some of the groundwater reserves are huge, so there is time to fix this, says Dalton. Its just theres no attention to it.
Inge de Graaf, a hydrologist at Wageningen University, who led the 2019 study into watershed levels, found between 15% to 21% had already passed ecological tipping points, adding that once the effects had become clear for rivers, it was often too late.
Groundwater is slow because it has to flow through rocks. If you extract water today, it will impact the stream flow maybe in the next five years, in the next 10 years, or in the next decades, she says. I think the results of this research and related studies are pretty scary.
In April, the largest ever assessment of global groundwater wells by researchers from University of California, Santa Barbara, found that up to one in five were at risk of running dry. Scott Jasechko, a hydrologist and lead author on the paper, says that the study focuses on the consequences for humans and more research is needed on biodiversity.
Millions of wells around the world could run dry with even modest declines in groundwater levels. And that, of course, has cascading implications for livelihoods and access to reliable and convenient water for individuals and ecosystems, he says.PG
In 2019, the European heatwave brought 43C heat to Montpellier in France. Great tit chicks in 30 nest boxes starved to death, probably because it was too hot for their parents to catch the food they needed, according to one researcher. Two years later, and 2021s heatwave appears to have set a European record, pushing temperatures to 48.8C in Sicily in August. Meanwhile, wildfires and heatwaves are stripping the planet of life.
Until now, the destruction of habitats and extraction of resources has had a more significant impact on biodiversity than the climate crisis. This is likely to change over the coming decades as the climate crisis dismantles ecosystems in unpredictable and dramatic ways, according to a review paper published by the Royal Society.
There are many aspects of ecosystem science where we will not know enough in sufficient time, the paper says. Ecosystems are changing so rapidly in response to global change drivers that our research and modelling frameworks are overtaken by empirical, system-altering changes.
The calls for biodiversity and the climate crisis to be tackled in tandem are growing. It is clear that we cannot solve [the global biodiversity and climate crises] in isolation we either solve both or we solve neither, says Sveinung Rotevatn, Norways climate and environment minister, with the launch in June of a report produced by the worlds leading biodiversity and climate experts. Zoological Society of London senior research fellow Dr Nathalie Pettorelli, who led a study on the subject published in the Journal of Applied Ecology in September, says: The level of interconnectedness between the climate change and biodiversity crises is high and should not be underestimated. This is not just about climate change impacting biodiversity; it is also about the loss of biodiversity deepening the climate crisis.
Writer Zadie Smith describes every countrys changes as a local sadness. Insects no longer fly into the house when the lights are on in the evening, the snowdrops are coming out earlier and some migratory species, such as swallows, are starting to try to stay in the UK for winter. All these individual elements are entwined in a much bigger story of decline.
Our biosphere the thin film of life on the surface of our planet is being destabilised by temperature change. On land, rains are altering, extreme weather events are more common, and ecosystems more flammable. Associated changes, including flooding, sea level rise, droughts and storms, are having hugely damaging impacts on biodiversity and its ability to support us.
In the ocean, heatwaves and acidification are stressing organisms and ecosystems already under pressure due to other human activities, such as overfishing and habitat fragmentation.
The latest Intergovernmental Panel on Climate Change (IPCC) landmark report showed that extreme heatwaves that would usually happen every 50 years are already happening every decade. If warming is kept to 1.5C these will happen approximately every five years.
The distributions of almost half (47%) of land-based flightless mammals and almost a quarter of threatened birds, may already have been negatively affected by the climate crisis, the IPBES warns. Five per cent of species are at risk of extinction from 2C warming, climbing to 16% with a 4.3C rise.
Connected, diverse and extensive ecosystems can help stabilise the climate and will have a better chance of thriving in a world permanently altered by rising emissions, say experts. And, as the Royal Society paper says: Rather than being framed as a victim of climate change, biodiversity can be seen as a key ally in dealing with climate change. PW
On the west coast of Scotland, fragments of an ancient rainforest that once stretched along the Atlantic coast of Britain cling on. Its rare mosses, lichens and fungi are perfectly suited to the mild temperatures and steady supply of rainfall, covering the crags, gorges and bark of native woodland. But nitrogen pollution, an invisible menace, threatens the survival of the remaining 30,000 hectares (74,000 acres) of Scottish rainforest, along with invasive rhododendron, conifer plantations and deer.
While marine plastic pollution in particular has increased tenfold since 1980 affecting 44% of seabirds air, water and soil pollution are all on the rise in some areas. This has led to pollution being singled out as the fourth biggest driver of biodiversity loss.
In Scotland, nitrogen compounds from intensive farming and fossil fuel combustion are dumped on the Scottish rainforest from the sky, killing off the lichen and bryophytes that absorb water from the air and are highly sensitive to atmospheric conditions.
The temperate rainforest is far from the sources of pollution, yet because its so rainy, were getting a kind of acid rain effect, says Jenny Hawley, policy manager at Plantlife, which has called nitrogen pollution in the air the elephant in the room of nature conservation. The nitrogen-rich rain thats coming down and depositing nitrogen into those habitats is making it impossible for the lichen, fungi, mosses and wildflowers to survive.
Environmental destruction caused by nitrogen pollution is not limited to the Scottish rainforest. Algal blooms around the world are often caused by runoff from farming, resulting in vast dead zones in oceans and lakes that kill scores of fish and devastate ecosystems. Nitrogen-rich rainwater degrades the ability of peatlands to sequester carbon, the protection of which is a stated climate goal of several governments. Wildflowers adapted to low-nitrogen soils are squeezed out by aggressive nettles and cow parsley, making them less diverse.
About 80% of nitrogen used by humans through food production, transport, energy and industrial and wastewater processes is wasted and enters the environment as pollution.
Nitrogen pollution might not result in huge floods and apocalyptic droughts but we are slowly eating away at biodiversity as we put more and more nitrogen in ecosystems, says Carly Stevens, a plant ecologist at Lancaster University. Across the UK, we have shown that habitats that have lots of nitrogen have fewer species in them. We have shown it across Europe. We have shown it across the US. Now were showing it in China. Were creating more and more damage all the time.
To decrease the amount of nitrogen pollution causing biodiversity loss, governments will commit to halving nutrient runoff by 2030 as part of an agreement for nature currently being negotiated in Kunming. Halting the waste of vast amounts of nitrogen fertiliser in agriculture is a key part of meeting the target, says Kevin Hicks, a senior research fellow at the Stockholm Environment Institute centre at York.
One of the biggest problems is the flow of nitrogen from farming into watercourses, Hicks says. In terms of a nitrogen footprint, the most intensive thing that you can eat is meat. The more meat you eat, the more nitrogen youre putting into the environment.
Mark Sutton, a professor at the UK Centre for Ecology & Hydrology, says reducing nitrogen pollution also makes economic sense.
Nitrogen in the atmosphere is 78% of every breath we take. It does nothing, its very stable and makes the sky blue. Then there are all these other nitrogen compounds: ammonia, nitrates, nitrous oxide. They create air and water pollution, he says. He argues that if you price every kilo of nitrogen at $1 (an estimated fertiliser price), and multiply it by the amount of nitrogen pollution lost in the world 200bn tonnes it amounts to $200bn (147bn) every year.
The goal to cut nitrogen waste in half would save you $100bn, he says. I think $100bn a year is a worthwhile saving.PG
On Gough Island in the southern Atlantic Ocean, scores of seabird chicks are eaten by mice every year. The rodents were accidentally introduced by sailors in the 19th century and their population has surged, putting the Tristan albatross one of the largest of its species at risk of extinction along with dozens of rare seabirds. Although Tristan albatross chicks are 300 times the size of mice, two-thirds did not fledge in 2020 largely because of the injuries they sustained from the rodents, according to the RSPB.
The situation on the remote island, 2,600km from South Africa, is a grisly warning of the consequences of the human-driven impacts of invasive species on biodiversity. An RSPB-led operation to eradicate mice from the British overseas territory has been completed, using poison to help save the critically endangered albatross and other bird species from injuries they sustain from the rodents. It will be two years before researchers can confirm whether or not the plan has worked. But some conservationists want to explore another controversial option whose application is most advanced in the eradication of malaria: gene drives.
Instead of large-scale trapping or poisoning operations, which have limited effectiveness and can harm other species, gene drives involve introducing genetic code into an invasive population that would make them infertile or all one gender over successive generations. The method has so far been used only in a laboratory setting but at Septembers IUCN congress in Marseille, members backed a motion to develop a policy on researching its application and other uses of synthetic biology for conservation.
If a gene drive were proven to be effective and there were safety mechanisms to limit its deployment, you would introduce multiple individuals on an island whose genes would be inherited by other individuals in the population, says David Will, an innovation programme manager with Island Conservation, a non-profit dedicated to preventing extinctions by removing invasive species from islands. Eventually, you would have either an entirely all male or entirely all female population and they would no longer be able to reproduce.
Nearly one-fifth of the Earths surface is at risk of plant and animal invasions and although the problem is worldwide, such as feral pigs wreaking havoc in the southern United States and lionfish in the Mediterranean, islands are often worst affected. The global scale of the issue will be revealed in a UN scientific assessment in 2023.
We have to be very careful, says Austin Burt, a professor of evolutionary genetics at Imperial College London, who researches how gene drives can be used to eradicate malaria in mosquito populations. If youre going after mice, for example, and youre targeting mice on an island, youd need to make sure that none of those modified mice got off the island to cause harm to the mainland population.
In July, scientists announced they had successfully wiped out a population of malaria-transmitting mosquitoes using a gene drive in a laboratory setting, raising the prospect of self-destructing mosquitoes being released into the wild in the next decade.
Kent Redford, chair of the IUCN Task Force on Synthetic Biology who led an assessment of the use of synthetic biology in conservation, said there are clear risks and opportunities in the field but further research is necessary.
None of these genetic tools are ever going to be a panacea. Ever. Nor do I think they will ever replace the existing tools, Redford says, adding: There is a hope and I stress hope that engineered gene drives have the potential to effectively decrease the population sizes of alien invasive species with very limited knock-on effects on other species.PG

The five biggest threats to our natural world and how we can stop them - The Guardian
Hunting: How can you tell the age of a deer? Here are some tips – pressherald.com
When most folks talk about aging deer theyre referring to venison, and the process of hanging a deer for an extended period to improve flavor and tenderness. However, with the rise in popularity of trail cameras, increasingly more hunters are sharing photos on social media and asking, How old is this deer?
When it comes to the answers you have to consider the source. A lot of well-meaning keyboard biologists offer their opinions, often of questionable accuracy. Fortunately, there are some fairly reliable though not foolproof methods for properly aging deer on the hoof, or from a photo. Lets start with does as they can only be reliably divided into two or three age classes. Early in the season its easy to distinguish does from fawns but as the youngsters grow it becomes more difficult, especially if you dont have multiple deer present for comparison.
First, look at the head and face. A fawns forehead and nose will appear much shorter (think: 8-ounce soda bottle) in comparison to the adult does longer nose (16-ounce soda bottle) and larger head. Next, look at the body. Fawns also have short, square bodies, short necks and less muscle development. An adult does body will be larger and more rectangular-shaped. Necks appear longer and older does may have swayed backs or sagging bellies.
Yearling does look somewhere in between and are best judged in the presence of older and/or younger deer. Its not uncommon for female deer to travel in family groups consisting of several generations, often a mature doe, her fawns and her yearling female offspring from the previous year. The same guidelines apply to buck fawns, though they may show a more square head than a doe, and sometimes you can distinguish tiny nubs or buttons that will eventually become antlers.
Now for the antlered bucks. Yearling bucks appear dainty, with thin necks, somewhat resembling a doe with antlers. Their legs appear long and slender compared to their body. Antler development can be highly variable depending mostly on nutrition and genetics. Many will sport spikes or forked antlers but some may carry a rack of six or even eight points. Regardless, main beams and points are usually thin and short.
Two-year-old bucks generally look somewhat gangly and awkward, though a healthy Maine buck could fool a lot of folks into thinking its older. Legs also appear long for their body, and theyll have a thin waist and shoulders and limited neck swelling. During the rut, tarsal glands may be dark, but very small and round. Rack size also varies but six-, eight- or even 10-point racks that score in the 120s and even 130s are not unusual, and a 2-year-old might dress out somewhere between 140 and 180 pounds, possibly more further north. Antler beams will still be relatively narrow at the base but thicker than a yearling and possibly have more rounded points.
Three-year-old bucks will have a fuller, thickly-muscled neck. The chest appears deeper than the hindquarters, giving a race horse appearance. Horizontal lines of the back and stomach are still straight and taut. Another good characteristic is that you can usually distinguish where the neck meets the shoulders. Tarsal glands during the rut will be dark but small, and staining does not extend down the leg to the hoof. Antler beams become thicker and could be 3 1/2 inches in diameter at the base.
At age 4, bucks reach maturity. Skeletal structure stops growing so they can direct more nutrition to body weight and antler mass. Their fully muscled neck now blends seamlessly into a deep chest. Their rump appears full and rounded and legs may appear slightly short for the body. The stomach and back do not sag, yet. Jaw skin is tight and tarsal glands will be noticeably large and dark. Rack size still varies but most of these deer will fall into what most hunters would consider the trophy category. The base of the beams will be thick, about the same diameter as a deers eye, and may show more dark staining.
Not many deer make it that long in heavily hunted areas but a few do, more so in the big woods where hunting pressure is less. Their neck and brisket will appear to be one continuous muscle and their neck will show heavy swelling. Now the legs really appear too short for the big, blocky body. Their waistline will be even (parallel) with the chest and they may start to show a pot belly and sagging back. Tarsals appear noticeably large and very dark with staining down the inside of the leg to the hoof during the rut. Again, rack size varies but even if they dont carry a crown of thorns, beams will be thick and heavy, especially at the bases.
There are objective criteria for what distinguishes a trophy buck, but for most hunters its a personal and very subjective judgement. A yearling might be a trophy for an inexperienced or unlucky hunter. Many 2- and 3-year-old bucks eventually make their way to the taxidermist. And a gnarly old north woods buck that wont score well in the record book but will pull the scales down well past the 200-pound mark might make the grade for big woods hunters. Still, if you plan to be selective, its nice to know what to look for.

Hunting: How can you tell the age of a deer? Here are some tips - pressherald.com
Alcohol Is the Breast Cancer Risk No One Wants to Talk About – WIRED
Martinez had never organized a social media campaign and doesnt consider herself social media savvy. But after ARG won the $100,000 grant, she was running focus groups, coordinating an advisory group of cancer organizations, building a team of co-investigators and partnering with the ARG communications specialist. The young women made it very clear they did not want to be told what to do, Martinez says of the focus groups. Drink less for your breasts felt more like a helpful suggestion.
Planning for the social media campaign began just as the pandemic forced a national shutdown. As the pandemic dragged on, alcohol consumption rose, especially among women. Days of heavy drinking among women, defined as four or more drinks within a couple of hours, rose by 41 percent, according to a survey by the RAND Corporation. (The study compared a baseline survey of 1,540 adults conducted in the spring of 2019 with their responses during a follow-up in the spring of 2020.)
But pushing back against alcohol consumption isnt simple. As the US found during a disastrous prohibition period from 1920 to 1933, opposing alcohol is not popular. When Sharima Rasanayagam,chief scientist for Breast Cancer Prevention Partnersin San Francisco, gives talks about environmental causes of breast cancer, her audience is raptuntil she mentions alcohol. People like to drink and they dont like to hear that, she says. She tells them that quantity matters: At the very least, drink less.
Its a message she delivers with care, to avoid giving women a reason for self-blame if they develop breast cancer and wonder Why me? Cases of breast cancer cant be tied to alcohol alone, because many factors, including genetics and environmental exposures, contribute to the disease, she explains in a YouTube video linked to the Breast Cancer Prevention Partners website. But Rasanayagam notes that risks add upand alcohol is one that women can reduce. Fewer drinks, whether over time or in one day, mean less exposure to acetaldehyde and potentially less effect on estrogen. Its been shown that the less you drink, the lower your risk, she says. (Breast Cancer Prevention Partners is an advisor to the Drink Less for Your Breasts campaign.)
Its a nuanced message but, in its own way, a bold one, as framed in a social media campaign, says David Jernigan, an alcohol policy expert at Boston University, who has been working in the field for 35 years. What Priscilla is doing in California is groundbreaking, he says.
Jernigan asserts that the harm from alcoholwhich also includes drunk driving and an association with violencewarrants a large-scale response similar to anti-tobacco efforts. He notes that in Estonia, a campaign urging Lets drink less by half! actually lowered per capita consumption by 28 percent. (Estonias alcohol policy also included restrictions on advertising, more enforcement of driving-under-the-influence laws, higher taxes, and a focus on treatment.)
The World Health Organization is also developing a global action plan; the current draft sets a goal of reducing per capita consumption by 20 percent by 2030 (with 2010 consumption levels as the baseline). It urges nations to develop and enforce high-impact policy options, such as higher alcohol taxes, restrictions on advertising, and emphasizes awareness of health risks.
Jernigan calls that effort a good step that doesnt go far enough. He favors the development of an international treaty on alcohol, similar to the Framework Convention on Tobacco Control, the first such negotiated through the World Health Organization. It has been signed by 168 countries that committed to taking steps to restrict tobacco advertising, raise cigarette taxes, and prevent youth smoking.

Why Black Women Are Twice as Likely to Die of Endometrial Cancer and What MSK Is Doing to Change It – On Cancer – Memorial Sloan Kettering
When Linda Collins was diagnosed with endometrial cancer in her early 60s, she wanted to find the best treatment possible.
After doing her research, she felt confident she would receive the care she needed at Memorial Sloan Kettering Cancer Center.
She also knew what she needed to give her peace of mind. When I called the MSK Patient Access Service to ask about an appointment, I told them that as a Black woman, I would feel more comfortable with a female doctor who is a person of color.
She explains that years before, I had a white, male gynecologist who dismissed concerns that I had. Respectfully, it seemed like he couldnt be bothered. And I have great insurance!
Linda searched the MSK website and knew she had found the doctor she hoped for in Carol Brown, a gynecologic oncology surgeon and MSKs Chief Health Equity Officer.
Dr. Carol Brown, gynecological oncology surgeon
Dr. Brown has devoted her career to improving cancer disparities that mean some groups of people suffer far worse outcomes, particularly Black people.
In May 2021, she launched an important new initiative as the leader of the Endometrial Cancer Equity Program (ECEP).Endometrial cancer develops in the lining of the uterus (womb) and is also sometimes referred to as uterine cancer.
The programs goals are to educate Black women about endometrial cancer, help those diagnosed find appropriate care, and ultimately find treatments to improve outcomes for all women facing the disease, like Linda.
The numbers are truly shocking.
Black women are nearly twice as likely to die of endometrial cancer as white women, even though the disease is actually slightly more common in white women than in Black women.
The number of cases of endometrial cancer is also on the rise, with the greatest increase among Black women.
Dr. Brown stresses that many factors play a role in the troubling disparity in endometrial cancer, including poorer access to health care in some communities, a lack of awareness among some providers, and research efforts that often have not included enough people who are Black, Hispanic, and Asian.
Dr. Brown says research also suggests another important factor may be a cruel twist of biology.
Dr. Brown points out that the disparity in survival between Black and white women diagnosed with endometrial cancer hasnt changed in four decades. Theres no question that if the difference was only about access to health care, the disparity would have at least narrowed. Thats what weve seen happen in cervical cancer and most forms of breast cancer, when you compare Black and white women. But not endometrial cancer.
One distinction coming into clearer focus is that Black women are more often diagnosed with rare but aggressive forms of endometrial cancer.
Black women are more likely to have papillary serous carcinoma of the endometrium as well as carcinoma sarcoma, Dr. Brown says. Cancers caused by these two types of cancer cells definitely lead to worse outcomes and that in itself is a biologic difference.
Ying Liu is a medical oncologist whose specialty is the genetic component of gynecological cancers. She works alongside Dr. Brown investigating cancer disparities.
Dr. Liu explains that one aspect we are looking at is whether these biological differences in the kinds of cancer more commonly found in Black women are not as well targeted by current treatments. That may explain some of the disparity in survival rates between Black and white patients.
The ultimate goal of research at MSK is to better understand these biological differences in endometrial tumors, down to the molecular level, and then use this knowledge to identify weaknesses in the tumors that are more common in Black women. Then, its about finding therapies to treat them.
Dr. Brown explains at MSK we probably have one of the largest groups of Black female patients in the country where we can analyze the genetics of their endometrial cancer tumors as well as their personal genetics.
Lindas diagnosis was an aggressive papillary serous carcinoma, the type that more commonly affects Black women. Fortunately, the cancer was caught at an early stage.
Linda recalls that within days of our first appointment, Dr. Brown performed a laparoscopic hysterectomy, which involves a much smaller incision, and also removed my fallopian tubes, ovaries, and nearby sentinel lymph nodes. To reduce the chance the cancer could come back, Linda underwent a short course of radiation.
Linda says of her treatment, the staff was just fantastic. And I love Dr. Brown. She was so proactive and always took the time to answer all my questions.
Today, Linda is doing the things she loves. She is a pillar of her community in the Bronx, serving as president of her building association, leading clothing drives for homeless shelters, and serving as a liaison with police associations, among other efforts.
After a 32-year career, most of it in government, she says I just love to serve people.
She also wanted to be sure she was around for her family, retiring from the working world in her mid-50s. She explains as a Black woman, you have the sense that your life expectancy might not be as long as the next person.
Dr. Brown and her colleagues hope their new initiative can help.
Since May 2021, the ECEP has participated in community events that have reached more than 500 women in predominately Black neighborhoods that stretch across Long Island, Brooklyn, and Queens.
In addition, Dr. Brown and colleagues including MSK nurse practitioner Latasha Anderson-Dunkley have screened over 20 women at high risk who have been identified through the ECEP. The goal is to assess whether the women have cancer or precancerous conditions and get them appropriate care.
Dr. Brown says its particularly important that women and their providers are aware of endometrial cancer because as cases rise, the symptoms of the disease are not always clear cut.
Traditionally, providers have focused on symptoms that include bleeding in post-menopausal women, who often have other symptoms such as obesity and diabetes, she explains. But this cancer can present as just a heavier-than-usual period bleeding in your 40s. Thats true of all women and particularly Black women.
For Linda, making women aware of how they can protect their health is just what the doctor ordered. To me, outreach and education is so important, because you dont know what you dont know. Too often, this kind of outreach doesnt happen in communities of color. But if it does, it can save lives.

Murder Island review a contest to solve the killing of a young woman? Bad timing – The Guardian
Its possible that the timing is not propitious for the launch of a new entertainment series centred on the investigation of a young womans murder. The outrage surrounding the conviction of a serving Metropolitan police officer for the rape and killing of Sarah Everard, and the visibility it has given to the endemic violence against women, is a hurdle to overcome. Channel 4s six-part offering Murder Island also has a further point of connection with the case and the context. One of its participants is former chief superintendent Parm Sandhu, who last week gave an interview to Radio 4s World at One about her experience in the Met. She discussed female officers unwillingness to report sexist and misogynist behaviour for fear that the men will close ranks, and said that the fear that most women police officers have got is that when you are calling for help, you press that emergency button on your radio, theyre not going to turn up and youre going to get kicked in the street.
On the other hand, the vulnerability of women to rapists and murderers is not exactly new information and it hasnt curbed appetites for its exploitation as entertainment before now. So maybe this is by the by. Plus, Murder Islands USP is that it is a new genre a hybrid drama/reality show that keeps the involvement of police proper to a minimum. Instead, four pairs of amateur detectives will compete to solve a murder mystery written by Ian Rankin, about the stabbing of Charly Hendricks in a cottage on a remote Scottish island by a person or persons unknown. One team will be eliminated at each stage of the investigation the winners get a 50,000 prize.
Put like that, I am even less sure than I was that this counts for rather than against the new venture.
Context aside, how does the new format fare? The reality show element sings its customary siren song, giving us competitors spanning the full range of capability. At one end of the spectrum are Andrew and Nick, ambitious, articulate and with the lean, hungry look of leopards on the prowl. Andrews father and grandfather were detectives and he is hoping genetics will out. Although they have to be warned like the rest about making assumptions rather than gathering evidence and seeing what it tells them, they seem to have a basic grasp of procedure and, when it comes to assessing timelines and comparing testimonies, logic. If you had money and cared enough, you would bet on them to win.
At the other end there are Dot and Rox, who have to be told not to stand in the blood pool at the crime scene. They became friends when they worked in the same pub, and reckon they know how to read people. This will be very useful once we move to an all-intuition criminal justice system, but, as things stand, makes them merely extremely fun to watch. Told off by Simon Harding, one of the former detectives who is overseeing and evaluating the teams, for taking more photos of the processed crime scene than he would take on holiday, they wonder aloud how boring his holidays must be.
As we cut between the reality show scenes, full drama scenes play out with the fictional characters. As the competitors travel around the village interviewing Charlys friends, acquaintances and other people of interest played by actors, a story builds of a proposed development on the island that is cleaving the community, Charlys activism on behalf of those against the scheme and a possible love triangle between her, Jean the shopkeeper and particularly dour local Hamish. There is also a pregnancy, mysterious events in the far-flung land of Glasgow that have yet to be fully uncovered and the pubs owner Toby looks shifty to us all.
The goal of all hybrid genres is to double the value of watching. On most occasions, however, it simply halves it because neither contribution is fully developed and each undercuts the others momentum. Murder Island, judged on the first episode, falls into the latter camp. Things may improve as teams are eliminated, allowing the hour to tighten up. It will help, too, if the interactions between the detectives and the actors become less stagey and awkward as they relax into the situation and its strange demands.
How much context matters, of course, is up to us.

One Major Effect Vitamin D May Have in Preventing Breast Cancer, New Study Suggests | Eat This Not That – Eat This, Not That
One question to startOctober: Are you getting enough Vitamin D?The benefits from Vitamin D seem never-ending, and now a new women's health study may point to yet one more. Biology researchers in a region with an "elevated risk of breast cancer" have zeroed in on a specific link between the disease and a nutritional deficiency.

In a new issue of the peer-reviewed journal, Nutrition and Cancer, three genetics and biochemistry researchers in Pakistan have published a new study, in which they state, "Pakistani females are at elevated risk of breast cancer."
They also note that Vitamin D deficiency is "an ignored contributing factor" to the illness, "despite a strong association."

The study included 154 women who had been diagnosed with breast cancer, and 248 selected at random for the control group.
The researchers note that out of these 402 women, 51.5% "were completely ignorant of their [Vitamin D] level." Between the women who weren't aware of their Vitamin D intake versus those who held some awareness, the researchers noted higher incidence of breast cancer among those who were entirely uncertain.
RELATED:These Foods May Increase Your Breast Cancer Risk, Says New Study
Upon analysis, the team discovered a couple insightful trends. They found that women ages 41 to 50 years old were most prone to a Vitamin D deficiency.
Interestingly, women in cities were 12% more likely to suffer a Vitamin D deficiency than women who lived in rural areas.
A possible explanation for this may be greater outdoor exposure to sunlight, which triggers the body to produce Vitamin D. Perhaps more importantly, the higher Vitamin D levels among rural woman might highlight the importance of having access to fresh, nutritious foods, thanks to their proximity to agriculture.

The 2021 winners: Cool Science Image Contest – University of Wisconsin-Madison
Ten images and two videos created by University of WisconsinMadison students, faculty and staff have been named winners of the 2021 Cool Science Image Contest.
A panel of nine experienced artists, scientists and science communicators judged the scientific content and aesthetic and creative qualities of scores of images and videos entered in the 11th annual competition. The winning entries showcase animals and plants, the invisibly small structures all around us, and stars and nebulae millions of millions of miles away.
An exhibit featuring the winners is open to the public at the McPherson Eye Research Institutes Mandelbaum and Albert Family Vision Gallery on the ninth floor of the Wisconsin Institutes for Medical Research, 111 Highland Ave., through December. A reception open to the public for the contest entrants will be held at the gallery on Oct. 7 from 4:30 to 6:30 p.m.
Winning submissions were created with point-and-shoot digital cameras, cutting-edge microscopes, and telescopes of both the backyard and mountaintop variety.
Because sometimes, theres no substitute for the visual.
An image often can convey meaning more effectively than words, says Ahna Skop, a longtime contest judge, artist and UWMadison professor of genetics and active ambassador for science. We know from marketing and education research that adding a picture with words to a slide increases retention of knowledge by 65 percent. The visual communication of science is critical for the transference of knowledge broadly.

There can be an ineffable sort of something that makes a particularly effective science image its the Cool in Cool Science Image Contest but the good ones have much in common.
Youll know it when you see it. Its like seeing Starry Night or the Mona Lisa for the first time, in person. They hit you deep and quickly, Skop says. They are beautiful to the eye, simple, and convey meaning. Some images just take your breath away.Looking deeper they exquisitely communicate the secrets of science beautifully.
The Cool Science Image Contest recognizes the technical and creative skills required to capture images or videos that capably reveal something about science or nature while also leaving an impression with their beauty or ability to induce wonder. The contest is sponsored by Madisons Promega Corp., with additional support from the UWMadison Division of the Arts.
Winning entries are shared widely on UWMadison websites, and all entries are showcased at campus science outreach events and in academic and lab facilities around campus throughout the year. Because there was no opportunity to show off the 2020 contest winners in-person, this years exhibit is a double-feature for both the 2020 and 2021 contests. See last years winners.

‘We’re Angry’: Medical Journal Apologizes for Referring to Biological Women with Trans-Inclusive Phrase – CBN News
The editor of a leading medical journal has apologized in the wake of outrage stemming from a recent cover of the publication referring to biological women as bodies with vaginas.
In the latest issue of The Lancet, the British-based journal featured a quote on the front cover from a peer-reviewed piece on the anatomy and physiology of bodies with vagina.
Richard Horton, editor-in-chief of the journal,issued a statementthis week in response to the backlash the publication faced for the terminology.
[W]e have conveyed the impression that we have dehumanized and marginalized women, he said. [I] apologize to our readers who were offended by the cover quote and the use of those same words in the review. At the same time, I want to emphasize that transgender health is an important dimension of modern health care, but one that remains neglected.
LISTEN TO TODAYS PODCAST AND SUBSCRIBE:
Horton defended the article by stating the article in question calls for greater efforts to overcome the lack of knowledge and stigma too often associated with menstruation.
These are serious issues that demand serious actions, he explained. We encourage people to read the full review and support a growing movement against menstrual shame and period poverty.
Critics saw the terminology as demeaning and an erasure of the female experience.
David Curtis, an honorary professor of genetics, evolution, and environment at University College London,arguedits difficult to imagine why any medical researcher would want to submit their paper to The Lancet journal when they are happy to refer to women on their front cover with language which would be considered inappropriate even in a red light district.
Another critic, Claire Heuchan, an author who describes herself as a black radical feminist,condemned the characterizationas sexist and hypocritical, noting The Lancet has not referred to biological males as bodies with penises.
This framing makes it sound like a coincidence that bodies with vaginas have been neglected medicine, as if it were not the product of a discrimination and oppression specific to the female sex, she wrote. Medical misogyny exists and refusing to acknowledge women perpetuates it.
Dr. Jane Clare Jones, who classifies herself as a philosopher and a feminist, took issue with Hortons apology,writingshe is not offended, as the editor suggested.
Were angry with your colluding with the political erasure of women, she explained. Especially in a context when you are supposed to be rectifying that historic erasure.
The dustup over The Lancets description of women came the same week people on social media rebuked the left-leaning American Civil Liberties Unionfor censoring a pro-abortion quoteby the late U.S. Supreme Court Justice Ruth Bader Ginsburg.
In 1993, as part of her written responses to questions submitted during her Senate confirmation hearing, Ginsburg wrote: The decision whether or not to bear a child is central to a womans life, to her well-being and dignity. It is a decision she must make for herself. When government controls that decision for her, she is being treated as less than a fully adult human responsible for her own choices.
The ACLU, however, edited her quote to be more trans-inclusive by removing any reference to women or female pronouns.

Bear incidents are rising in the North Bay. Biologists sent in a wildlife tracker to find out why – San Francisco Chronicle

Meghan Walla-Murphy stooped to examine a twisted pile of dried poop, obscured by golden grass on an arid ridge in eastern Napa County. It may have belonged to one of the feral pigs that run rampant in the area. Or it may have been evidence of black bears, whose presence in Wine Country appears to be on the rise.
Walla-Murphy picked it up for a closer look.
No undigested identifiers, she said. Probably pig. She set it down and kept hiking.
Walla-Murphy, 46, is an ecological consultant and wildlife tracker who lives in western Sonoma County. Two years ago, she started the North Bay Bear Collaborative, an effort to bring together state wildlife experts, land managers, property owners, nonprofits, tribes and researchers for discussions about cultivating a bear culture in California.
On a recent survey near Atlas Peak in Napa County, Walla-Murphy and a pair of volunteers found 13 signs of bear scat and claw marks on the trunk of an oak.
Volunteer Alan Studley holds what appears to be a charred deer skull found in the slopes of Foss Valley.
The bears are here in the North Bay now, Walla-Murphy said. So, how do we figure out how to live with them?
Incidents involving black bears are escalating in the mountainous areas of Napa, Sonoma and Marin counties, and state wildlife biologists want to know why. Nuisance reports have jumped from an average of about 67 per year from 2010 to 2016 to more than 200 last year and upward of 200 so far this year, according to the California Department of Fish and Wildlife.
Sightings reported to the department have also climbed significantly in the past decade. One of the creatures was even spotted two years ago sauntering through downtown Napa highly unusual behavior.
A running theory is that the rise signals the southern expansion of a large black bear population in Mendocino and Humboldt counties, which could portend more bear-human encounters to come in the greater Bay Area.
If the bears are getting pushed toward the Bay Area, thats their southern limit. Theres real potential for human-wildlife conflicts, said Stacy Martinelli, a wildlife biologist at Fish and Wildlife. Were trying to understand whats going on, so we can make some management decisions before that happens.
Ecological consultant Meghan Walla-Murphy (left) of Sonoma County leads volunteers on a hunt for bear scat in the hills above Foss Valley in Napa County.
First, they need to know how many bears are roaming around.
In decades past, wildlife managers divined population estimates from the number of unique bear teeth provided by hunters and aerial surveys via helicopter crude, imperfect tactics at best. Estimates from Fish and Wildlife put the state black bear population at 30,000 to 40,000 in 2016, up from 10,000 to 15,000 in 1992. Activity around Lake Tahoe, the unofficial black bear capital of California where the animals live about one per square kilometer, is fairly well documented, but its a mystery most everywhere else.
We really dont know as much as we should know about whats happening with bears in different places around the state, Martinelli said.
In the past two years, Fish and Wildlife has embarked on a study that uses genotyping to identify and sex individual black bears in the North Bay by their DNA. Its a relatively new and much less disruptive method that has helped the state more accurately monitor populations of deer, elk and the Sierra Nevada red fox, which was recently listed as an endangered species.
State biologists hope to eventually track bears movements and plot their home ranges as well, which could help the North Bays rural residents better prepare to coexist with their furry new neighbors. Bears have been known to show up at vineyards this time of year to munch ripe grapes off the vine and suck down water from irrigation ponds.
This approach hinges, in part, on the expertise of Walla-Murphy and participation from the bear collaboratives volunteers: The biologists need DNA samples, and the best way to get them is by finding bear excrement. Another way to gather DNA is by setting out hair snares in bear territory designed to snag fur from the animals. But that involves the labor-intensive process of lugging bales of barbwire into remote areas.
Meghan Walla-Murphy hikes into Foss Valley in Napa County during a recent scat survey.
For the past year, Walla-Murphy has orchestrated volunteer surveys in Sonoma, Napa and Marin, and collected hundreds of scat specimens. The samples are processed at UC Davis and logged into a growing database of individuals with identifiers such as Sonoma Female 1 as well as their locations. The more samples Walla-Murphy and her revolving group of volunteers collect, the clearer the picture of bear activity becomes.
With a robust flow of these data points, we can study reproductions, survival, their space use and if theyre concentrating, say, near places where people are leaving their trash out, said Ben Sacks, a UC Davis professor of mammalian genetics who is handling the DNA analysis. There is tremendous potential for these noninvasive genetic methods and a lot of untapped applications.
A deeper dive into the scat specimens could illuminate the bears diets and show whether a given female is pregnant, Sacks said. But thats beyond the scope of the current study. For now, the goal is to get an accurate count and a snapshot of where theyre ranging.
Several factors could be pushing more black bears south toward the Bay Area: drought, food shortages, wildfires or just steady growth of a healthy population.
Usually its not one reason, its multiple reasons, Martinelli said.
Back on the scat hunt in Napa, Walla-Murphy led two volunteers across a ridgeline above Foss Valley, a narrow avenue largely given over to grape-growing, which partially burned in the Glass Fire last year. Amid the blackened landscape, new plant life was emerging: Wildflowers blossomed, and bright, leafy tufts of oak resprouted from charred root crowns.
Walla-Murphy has surveyed this area for years and noticed that the fire didnt chase away the bears for long, like one might have assumed. The animals were present before the fire and returned almost immediately afterward.
Wildlife tracker Meghan Walla-Murphy (second from right) and two volunteers look across vineyards in Napa Countys Foss Valley. The North Bays black bear population is growing.
The fires are often creating more food forage-ability for bears, Walla-Murphy said. We see deer and foxes and bobcats come back right away as well. The animals know how to live with fire.
Within that simple observation is an insight Walla-Murphy hopes will steer the direction of bear management in California: A more natural landscape supports more natural animal behavior, which makes living with wildlife easier for humans.
If we can really begin to steward and tend our landscapes better so that theres more diversity and theyre regenerative and they have more forage for wildlife, that ideally will keep the bears in their natural habitat rather than pushing them into cities for food, she said.

Pune-based J K Trust to soon attain 100 IVF pregnancies from Gir cow Samadhi – The Indian Express
Samadhi, a cow, is likely to become the proud mother of 100 calves with the application of in-vitro fertilisation. At Phaltan in Satara district, farmer Dayaram Thengil, is overjoyed that eight surrogate cows from his herd, are carrying the pregnancies through IVF of Samadhi, a Gir cow.
Dr Shyam Zawar, chief scientist at J K Trust a city-based NGO working in the field of animal husbandry, which has set up a state-of-the-art in-vitro fertilisation-embryo transfer laboratory at Vadgaon Rasai told The Indian Express that a cow in its lifespan of 15-16 years will give birth to a maximum of 8-10 calves. Our lab was set up in 2016 to produce IVF embryos from elite indigenous cows such as Gir and Sahiwal, Zawar said. The cattle IVF and ET technology, which is being widely used around the world, can be customised and adapted to suit Indian climatic conditions, Zawar said.
The Trust has succeeded in establishing 74 IVF pregnancies from Samadhi in just 12 months and plans to reach 100 IVF pregnancies in the next two months.
Of these 74 IVF pregnancies, 30 IVF calves have already taken birth at various farms across the country, including Pune, Ahmednagar and Satara districts.
Of the 10 recipient cows, eight are confirmed pregnant and they are about to calve in a weeks time. The semen used for IVF was that of the famous Brazilian Gir bull namely Espanto, Zawar told The Indian Express.

Dayaram, too, said he was amazed when eight of his cows were confirmed pregnant in such a short time. IVF is a reproductive technique where matured eggs are harvested from a female and fertilised with sperm in a laboratory. The fertilised egg is planted in the body of the female animal after 6-7 days when cell division starts. The embryo develops normally after its gestation period.
IVF is mostly used in bovine animals to plant an embryo of superior genetics into a surrogate mother. After the normal gestation period of nine months, the calves that are reared have the traits of the original mother and father. Normally, in such cases, the egg is harvested from an animal with proven milk yielding capacity and crossed with the sperm of a male whose mother has well documented genetics. Once fertilised, the zygote is planted in the womb of the surrogate mother, whose qualities the calf does not inherit.

Israeli group to research link between menstrual changes and COVID vaccines – Haaretz
A little over a week after S., 34, received her second vaccination against COVID, at a time when she was menstruating, she was surprised to discover that she had begun menstruating again.
It was strange because my period is as regular as a Swiss watch. At first, I didnt give it any thought, but two weeks later I got my period again for seven days. Two weeks after that, bleeding that lasted four days. It turned out that for almost six months there were more days when I bled than when I didnt. After I talked to my friends, I realized the phenomenon is much more widespread, she said.
Growing evidence from Israel and abroad is showing that the phenomenon extends much beyond S.s social circle. In February, shortly after women of childbearing age began receiving the second shot, many of them posted on social media that they were experiencing changes in their menstruation shortly after the shot, such as irregularity and increased bleeding. Other women reported that they had begun bleeding years after menopause.
The medical establishment could not explain the phenomenon or associate it with the vaccination, among other things because irregular menstruation is common and influenced by many factors. It is usually not considered exceptional. However, the mounting complaints and increased concern women were showing over taking the shots due to the phenomenon, has spurred the medical community to look into the matter. Preliminary research has been published in Britain and the United States, and the U.S. government has allocated $1.67 million for research on the subject.
Prof. Roni Maimon, chairman of the Israel Society of Obstetrics and Gynecology, is moving ahead on the first Israeli study of the subject. In terms of biochemistry and endocrinology, we havent found a connection between disruption of menstruation and the vaccination. However, because we live in an age of evidence-based medicine, we decided to look into the phenomenon among a large number of women in Israel, he said. The exact number of women who will participate in the study is not yet decided.
The Health Ministry said it doesnt have exact data on the extent of the phenomenon in Israel. It has received reports, but because the condition is common and does not require hospitalization, there is no way to know how common it was in the population [before the vaccinations] and whether it is now more common. The ministry said similar reports have been received by major healthcare agencies abroad, and that the phenomena appear to be temporary and carry no risk.
The issue has become a topic of discussion on social media in terms of whether to take the third shot. For example, on the Facebook page Medicine for Women in Israel, one woman wrote: The two first shots brought on my period early, and six months later I began to experience bleeding between periods and irregular periods, and at the moment they cant figure out why Im very undecided about the booster.
The matter has also raised concerns aboutpossible damage to fertility. As H., 39, told Haaretz: After the first and second shots I had some irregularities in my period . The doctor explained that its because the immunological system is connected to the hormonal system, and its not really dangerous. However, H. added, In June, I started trying to get pregnant by artificial insemination. When they started talking about the booster, I was in the middle of hormone treatment. I asked the doctor whether to get the booster, and he said he didnt recommend it, that if I got pregnant, I should take it only after they see a heartbeat. When the insemination didnt work, I took got the booster.
Based on the data that has been collected, the theory is that the symptoms are connected to the vaccination but that they apparently do not stem directly from a specific vaccination. Experts believe this is the immune systems response to various vaccinations, including those not based on mRNA, like those of Pfizer and Moderna.
Dr. Ido Solt, head of Maternal Fetal Medicine at Rambam Health Care Campus in Haifa, said that although the phenomenon is connected to vaccination, it is apparently insignificant because it appears with Pfizer, Moderna and other vaccinations even though they use a different method of immunization. The theory is that this is not about a specific component of the vaccine, but rather another manifestation of an immunological response, he said.
Solt added that the papillomavirus vaccine is also known to cause menstrual irregularity. At present, women of childbearing age who contracted COVID reported phenomena of this type, Solt said.
In light of this, the treatment policy is that if the changes go one for more than two or three periods, or if a woman in menopause begins to menstruate, the case is treated as if she had not been vaccinated, Solt explained.
Its true that the vaccination impacts menstruation and can cause bleeding, but there is no evidence that this harms menstruation or fertility, Solt added. He said the symptoms had been compared to occurrences in the general population and in clinics and no negative effect had observed.
Conclusions so far
In Britain, health care authorities and researchers have said that data collection in a published study was based on voluntary reporting by women, which makes it difficult to reach definitive conclusions. Different research approaches need to be used to examine the differences between vaccinated and unvaccinated women with these symptoms.
The study, published about two weeks ago in the medical journal BMJ examined more than 30,000 reports of women with irregular menstrual symptoms from the beginning of the vaccination drive and until September 2. Most of the women who reported irregularities said things returned to normal by their next period, according to the researchers, who are from the Imperial College School of Medicine and Westminster Hospital. Unplanned pregnancies occurred at similar rates among vaccinated and unvaccinated women, and pregnancy rates at fertility clinics were similar in vaccinated and unvaccinated women.
The research indicated that the symptoms appeared among women vaccinated with vaccines using different means of immunization. The study concluded that if there is a connection between vaccination and menstruation, it is not due to a specific component in the vaccine.
In response to the study, Dr. Joe Mountfield, vice chancellor of the Royal College of Obstetrics and Gynecology, was quoted as saying there is no proof that the temporary changes would impact a womans future fertility. He recommended that taking the vaccination was important especially if a woman was planning to get pregnant, because of the higher risk pregnant women run of contracting COVID.
The Israeli Fertility Association will be holdings its annual conference on Monday, at which the impact of the vaccination on male and female fertility will be discussed. Dr. Talia Eldar-Geva, head of endocrinology and genetics at Shaare Zedek Medical Center and a former head of the association said, There is still no work dealing with long-term effects on fertility, but in the short term, there is no difference in response to fertility treatments, the number of eggs or the quality of the fetuses among men and women who have been vaccinated.

NIH awards Brown $10.8M to expand data-informed research to fight human disease – Brown University
PROVIDENCE, R.I. [Brown University] Five years after an $11.5 million federal grant launched the COBRE Center for Computational Biology of Human Disease at Brown University, the National Institutes of Health has awarded $10.8M in new funds to Brown to build on the centers early success.
The center a federal Center of Biomedical Research Excellence funded by the NIHs National Institute of General Medical Sciences uses sophisticated computer analyses to advance research aimed at understanding and fighting human diseases.
Director David Rand, a professor of biology at Brown, said the renewal funds will enhance the centers research infrastructure, enable strengthened collaboration among scientists working with computational and bioinformatics tools, and support four new research projects. Rand said there is a computational revolution happening in the biomedical sciences, as researchers need computational analyses to help them make sense of massive amounts of available data.
Even those working in wet labs or clinics who dont use computers in their daily work will at some point need assistance in analyzing complex data sets, he said.
Rand compared the current moment to the molecular biology revolution thats been changing science since the 1970s, when DNA cloning and sequencing became standard tools used by researchers across diverse fields. Computational analysis is bringing groups together today in a similar way, he said. For example, people working in engineering, computer science, basic biology and medicine will face situations where they need to convert data sets into information that can help them find solutions and answer questions. While their research projects are highly distinct, he said, the data analysis work shares common themes.
In addition to helping researchers with individual projects, we view the Center for Computational Biology of Human Disease as a vehicle for raising the level of computational ability for researchers in the community overall, Rand said.
To provide that service to COBRE project leaders and researchers across Brown, the center is home to a Computational Biology Core a group of four scientists, data analysts and software engineers who support data-intensive research. With the renewal grant, center leaders will work to build sustainable support for the group through continued funding to its scientists and support to ensure that four members are at the Ph.D.-level (past budget included support for two Ph.D.s and two masters-level scientists).
Everyone has large data sets and needs to convert these into useful information, and we aim to help people achieve that goal, Rand said. The center brings together researchers in the lab and clinic with exceptionally skilled and creative data scientists to turn data into information.
Funds from the grant will also support the research of junior faculty investigators and help position them to earn additional, longer-term funding for their work enabling them, Rand said, to build upon discoveries and continue their research while freeing up center funds to seed innovative new projects. With the initial $11.5 million from the NIH in the centers first phase, faculty projects at the Center for Computational Biology of Human Disease generated an additional $17.9 million in grants in areas of research such as human genomics, immunology and infectious disease, microbiome and machine learning approaches to complex genetics.

Genetic mapping of subsets of patients with fragile X syndro | TACG – Dove Medical Press
Introduction
Fragile X syndrome (FXS), OMIM # 300624, is a X-linked inherited genetic disease classified as a triplet repeat condition. FXS is the most common cause of inherited intellectual disability and autism in the world. It has a prevalence of 1 in 5000 men and 1 in 8000 women. Affected individuals are characterized by intellectual disability, autism, language deficit, typical facies, and macroorchidism.1,2
Alterations in the FMR1 gene with locus Xq27.3 are causative of Fragile X Syndrome and other disorders. This gene harbors a CGG repeat within the 5 untranslated region and, depending on the number of repetitions, 4 types of alleles are defined with different clinical manifestations:3 Normal alleles, which have up to 44 CGG repeats; grey zone or intermediate alleles that contain between 45 and 54 repeats; premutation (PM) alleles with between 55 and 200 repeats; and full mutation (FM) alleles, with more than 200 repeats. In most cases, this is due to an expansion of the CGG triplet from one generation to the next.4
The Fragile Mental Retardation Protein (FMRP) is coded by the FMR1 gene. The absence of FMRP expression is usually secondary to the methylation of the FMR1 gene that occurs when more than 200 CGG repeats are present in the 5UTR region; this can also be explained by a point mutation in the coding region for FMR1 or a deletion that includes this gene, but these changes have only been reported in a few cases. The absence of FMRP is related to the classic FXS phenotype.5,6
FMRP expression is slightly lower in the carriers of a PM allele. Lower levels of FMRP are found particularly in the upper premutation (PM) range however, they typically do not present the classic FXS syndrome phenotype.7 Furthermore, they have elevated FMR1 mRNA levels between 2 to 8 times normal levels, which also leads to RNA toxicity. These elevated levels of mRNA are a risk for a number of medical conditions that are not explained by decreased FMRP.2,4,8
FMRP has roles in chromatin dynamics, RNA binding, mRNA transport, and mRNA translation9,10 and for certain subgroups of cerebral transcripts.11
This protein is involved in the regulation of RNA stability, subcellular transport and translation of neural mRNAs that codify proteins involved in synapsis development, neural plasticity and brain development.8
In addition, FMRP interacts with at least 180 proteins expressed in the brain and connective tissue. This interactome comprises known FMRP-binding proteins, including the ribosomal proteins FXR1P, NUFIP2, Caprin-1, and other novel FMRP-interacting candidate proteins located in different subcellular compartments, including CARF, LARP1, LEO1, NOG2, G3BP1, NONO, NPM1, SKIP, SND1, SQSTM1 and TRIM28. This interactome suggests that, besides its known functions, FMRP is involved in transcription, RNA metabolism, ribonucleoprotein stress granule formation, translation, DNA damage response, chromatin dynamics, cell cycle regulation, ribosome biogenesis, miRNA biogenesis and mitochondrial organization.9
Several studies have shown that in the absence of FMRP, a wide range of neural mRNAs are affected, boosting neural protein synthesis, which results in dendritic spine dysmorphogenesis and glutamate/GABA imbalance, which in turn produce variations in neural excitation/inhibition, phenomena that are present in FXS. Dendritic spine dysmorphogenesis plays a role in the intellectual deficits and behavioral problems, due to the weak synaptic connections found in this syndrome.12,13
Fragile X syndrome (FXS) has incomplete penetrance and variable expressivity and biological sex is a decisive factor of the phenotype. Full mutation of the FMR1 gene has a 100% penetrance of intellectual disability in males and 60% in females. Other characteristics associated with FXS Appear with varying frequencies in affected individuals. Autism spectrum disorder (ASD) symptoms appear during early childhood in 50% to 60% of males and 20% of females with FXS.1417
Physical features include elongated face, large and prominent ears (7578% of affected males), mandibular prognathism (80% of adult men), hyperlaxity and macroorchidism (95% of adult men). Other characteristics also vary in their frequency of presentation: seizures (23%), strabismus (8%), and cardiac abnormalities such as abnormal aortic root dimensions (18%) and mitral valve prolapse (55%). In general, the female phenotype is less severe and less specific.4,18
The variation in the phenotype of monogenic diseases is common,19,20 it is explained by a combination of genetic, environmental, and lifestyle factors,21 and FXS is not an exception.
Here, we present a review of the knowledge about the molecular factors involved in the variable expressivity of FXS.
The presence of a full mutation in FMR1 is associated with the hypermethylation of a CpG island located in the promoter of the FMR1 gene. Methylation of DNA regions (mDNA) is one of the main epigenetic modifications related to transcription regulation.22 A CpG island is located proximal to the CGG repeat tract, which is expanded in FXS. Hypermethylation of the CpG island generates transcriptional silencing of the FMR1 gene.23 As a consequence, the Fragile Mental Retardation Protein (FMRP), codified by the FMR1 gene, is not produced24 and in turn, the absence or low expression of FMRP causes FXS.
CGG tract repetition expansion in the untranslated region (UTR) of exon 1 in the FMR1 gene generates instability of that region during the replication process, inducing size mosaicism, which is defined as the presence of premutation and mutation alleles in several cells.25
In males with FXS caused by full mutation, the detection of FMR1 mRNA levels in peripheral blood lymphocytes is common. This phenomenon is due to both size mosaicism and mDNA in the CpG island and nearby regions that vary between cells and tissues.26 Furthermore, longitudinal studies in women with FXS have shown that levels of mRNA transcribed from FMR1 decrease significantly with age.23 Complicating even more the behavior of mDNA and FXS, it has been found that in premutation alleles, a considerable number of cells have mDNA.27 The variation between methylation states of the CpG island and nearby regions among different cells and tissue of the same person is known as methylation mosaicism.28 It is estimated that around 50% of people with FXS have this type of mosaicism.29 In cells where mutated alleles are not methylated, they are transcriptionally active and can be expressed.30 However, in these cells there is no FMRP synthesis since mRNA with CGG expansion greater than 200 repeats is not translated efficiently in ribosomes.31,32
The absence or low levels of FMRP is a decisive factor for FXS development, as several studies have aimed to discover the relationship between protein levels and phenotypic characteristics of the patients. Since the late 1990s, correlations between FMRP levels and the neurological phenotype of FXS have been established.29,33,34 The first studies about this topic established the standard levels of FMRP in peripheral blood leucocytes through immunoblotting. When comparing protein levels with the allele type and the presence of size mosaicism, it was demonstrated that people with the lowest FMRP levels were males with FM. Males with size mosaicism and females with FM had slightly higher levels of FMRP than males with FM.33,35,36 Via multiple regression models, it was found that FMRP levels were significantly correlated with the intelligence quotient (IQ) of the patients in the study.33 However, studies did not identify the same relation between FMRP levels and behavioral symptoms.34,37 More recent evidence supports a partial overlap between the pathogenic mechanisms that lead to FXS and ASD.38 Lower FMRP levels have been documented in samples of individuals with FXS and ASD compared to patients with FXS only.29,34 The relation between FMRP levels and IQ in males and females with different expansions in CGG repeats was studied recently.39 This last study has two important advantages compared with previous studies: firstly, the use of fluorescence resonance energy transfer (FRET), which has a higher sensibility when measuring protein levels, and also FMRP levels were measured in dermal fibroblasts. Unlike leucocytes, fibroblasts derive from the ectoderm, the same germ layer from which nervous system cells originate. Researchers found a strong and positive relation between FMRP levels and cognitive skills in patients with levels below 30% of the standard levels in controls. Interestingly, above this level, there was a higher dependence between low FMRP levels and low IQ.39
In parallel with the aforementioned studies, researchers reported the incidence of size and methylation mosaicism in cognitive impairment severity.4042 The classic definition of premutation alleles behavior as non-methylated alleles, and mutated alleles as methylated or partially methylated ones in order to categorize premutation carriers and patients with FXS has been extended progressively to include a detailed classification that takes into account the existence of size and methylation mosaicisms.
Regarding size mosaicisms, different combinations have been described, including patients with some FM cells and other cells with PM. Indeed, patients with FM, PM, grey zone alleles and even alleles with normal size have been reported.40 The presence of size mosaicisms with PM and FM alleles is related with a less severe phenotype and a higher risk of developing fragile X-associated tremor/ataxia syndrome (FXTAS).43
When exploring the possible relation between size mosaicisms and the intellectual functioning of patients with FXS disregarding sex, it was found that patients with FM/PM had better intellectual functioning and less maladaptive behavior, compared with FM-affected individuals.42 Interestingly, the same study found that ASD features and maladaptive behaviors were similar between FM-only and PM/FM mosaics within each sex, after controlling for overall intellectual functioning. A limitation of this study is that they used venous blood and real time PCR and Southern blot analysis to quantify the level of methylation.
Recently, methylation mosaicism has been taken into account as an important variable in phenotype traits. The most frequent mosaicism found in males is the presence of FM-methylated alleles and non-methylated FM and PM alleles (combination of size and methylation mosaicism).25,44 However, in patients with FM and not PM mosaicisms, methylated alleles do not express mRNA, while non-methylated alleles do. An aspect that highlights the importance of detecting the presence of this kind of mosaicism is the influence on phenotype severity. Additionally, according to some case reports, the presence of synthesized mRNA from PM and FM alleles increases the odds of developing the FXTAS phenotype.45,46 The final consequence of methylation mosaicism is the cells reduced ability to express FMR1 mRNA, measure mRNA and determine if there is a relation with phenotypic traits. When analyzing mRNA levels between males and females, it was found that females had higher levels. Also, in females, higher levels of FMR1 mRNA were related positively with age but not with intellectual functioning and autistic features. Males with FM that express FMR1 mRNA had significantly higher ADOS calibrated severity scores, when compared with males with fully methylated FM. Interestingly, no differences were found regarding intellectual functioning.41 Likewise, when contrasting FMR1 mRNA levels and scores on the Aberrant Behavior Checklist-Community-FXS version (ABC-CfX) it was found that in males with FM, higher values of FMR1 mRNA were related with elevated irritability and lower health-related quality of life scores.47 This association was not found in males with PM/FM, suggesting that for improved genotype/phenotype associations, it is essential to take into consideration not only sex but also size and methylation mosaicism.
Recent investigations explored simultaneously how FMR1 mRNA levels of FMRP are related to phenotypic alterations in males with PM and FM.48 In a study composed of 14 cases of patients with PM or PM and FM mosaicism and mental illnesses such as bipolar disorder, schizophrenia and psychosis, among others, low levels of FMRP and increased FMR1 mRNA were evident in these patients. This combination of characteristics in patients with FM, decreased FMRP, PM and increased FMR1 mRNA represents a dual mechanism of clinical significance that may generate characteristics of both FXS and FXTAS.48 In a clinic-based ascertained group of patients with FXS of both gender, a significant difference was found between FXS with ASD and low levels of FMRP when comparing concentrations of the protein in patients with FXS without ASD.29 They found that the mean full scale IQ and adaptive skills composite scores were significantly lower in males than in females (p = 0.016 and p = 0.001, respectively, MannWhitney). Additionally, all individuals with moderate or severe ID were males. Not surprisingly, ASD was present more frequently in males with FXS (46% vs 20% females). This association was not found in males with PM/FM, suggesting that for improved genotype/phenotype associations is essential to take into consideration not only sex but size and methylation mosaicism.29
There is a small proportion of FXS patients without expansions in the CGG-repeat tract. In this group, the condition is caused by missense or nonsense mutations,5,16 or deletions in FMR1.1,6 Patients with these mutations have similar physical, cognitive and behavioral characteristics to FXS patients. With the increasing availability of diagnostic methods based on next-generation sequencing and comparative genomic hybridization, a higher rate of diagnosis of mutations causing FMR1 function loss is expected. This will allow a clear delimitation of the phenotype caused by the loss of the protein in the absence of CGG tract expansions.
For many monogenic diseases it is known that, besides the allelic variance, the effect of modifier genes has an important role in incomplete penetrance and variable expressivity. The identification of modifier genes that affect the phenotype in monogenic diseases has many challenges that complicate their description. A genetic variant can modify the effect in the phenotype of another variant in many ways, including epistasis and genetic interactions.49,50
In studies using FXS murine models, important new evidence was acquired in order to establish the importance of potential modifier genes and their impact on FXS phenotype development. The knockout mouse model for FXS was generated in the last decade of the XX century. Fmr1 KO mice had learning deficits, abnormal synaptic connections, seizures, hyperactivity and macroorchidism.51,52 When describing the mouse phenotype in detail, it was evident that abnormal phenotypic characteristics depend, at least in some proportion, on their genetic background.53
During the identification of modifier genes in the FXS phenotype, a large proportion of the research has aimed towards the susceptibility to developing certain clinical behavioral characteristics, such as aggression, ASD and seizures.34,5459 All of the studies use a similar methodological design: they arrange groups of people with or without a specific phenotypic trait and establish the frequency of specific variants in modifier gene candidates.
The possibility that Val66Met polymorphism in the brain-derived neurotrophic factor (BDNF) gene may modulate the epilepsy phenotype in FXS patients has also been investigated. The replacement of a methionine for a valine in the 66th position of the BDNF protein interferes with normal intracellular traffic and BDNF dependent secretory activity in cortical neurons.60 This polymorphism has been related to cerebral anatomy alterations61 and neuropsychiatric disorders.62,63 In a sample of 27 males with FXS from Finland, it was found that all the patients with epilepsy (15%) had the Met66 allele, whereas the prevalence of this allele is 20% in the normal population. Research suggests that the Met66 allele in BDNF interacting with FM in FMR1 may partially explain the higher incidence of seizures in patients with FXS.56 In a more recent study with a higher number of males with FXS (77 patients), the results were not replicated and there was no association between seizures and Val66Met polymorphism.58 These results show the importance of validating studies about modifier genes in different populations.
In research about genes that affect mood and aggression, such as the serotonin transporter (5-HTTLPR), the monoamine oxidase A (MAOA-VNTR) and COMT, conflicting results were found. All of those genes are involved in regulatory pathways for different neurotransmitters, and their variants have been associated with the development of behavioral phenotypes in different contexts other than FXS. In one group of 50 males with FXS, the relationship of 5-HTTLPR and MAOA-VNTR polymorphisms with the frequency/severity of aggressive/destructive, self-injurious and stereotypic behaviors was studied. It was found that the high-transcribing long (L/L) genotype in 5-HTTLPR was related with a higher frequency of aggressive/destructive and stereotypic behavior, while patients with the short (S/S) genotype had less aggression. The MAOA-VNTR genotype had no effect on behavior.55 On the other hand, in a study of 64 males with FXS where the COMT gene was also included, the results of the previous study were not replicated. There was no association between behavioral characteristics and either 5-HTTL PR (serotonin) or MAOA genotypes. Nevertheless, the A/A genotype in COMT that modifies dopamine levels was associated with greater interest and pleasure in the environment, and with less risk of property destruction, stereotyped behavior and compulsive behavior.54 The authors of the study suggest that the non-reproducibility of the results regarding MAOA-VNTR can be explained by differences in the prevalence of aggressive and stereotyped behavior among the studied populations or by differences in the measurements used to characterize each behavior.
The importance of identifying potential modifier genes was explored in a clinical trial. The researchers investigated the relation between polymorphisms in several genes and the response of sertraline in 51 children. They found that BDNF, MAOA, 5-HTTLPR, Cytochrome P450 2C19 and 2D6 polymorphisms had significant correlations with treatment response.64
Currently the knowledge about molecular causes of the variable phenotype in patients with FXS include characteristics associated with the FMR1 gene itself and to secondary, modifying gene effects.
Regarding FMR1, when the diagnosis is established, the type of mutation causing FXS is identified: CGG repeat tract expansion vs pathological variant causing loss of function in FMR1.
When the CGG is identified, is it expected that about half of the patients have size or methylation mosaicism or both.29 The presence of any of those mosaicisms determines the expression or not of FMR1 mRNA and FMRP. The quantity of FMRP is directly related with IQ.34,37,39 While the presence of size mosaicism is related with better intellectual functioning and less maladaptive behavior,29,42 elevated concentrations of FMR1 mRNA in patients with FM have been associated with a higher risk of developing FXTAS45,46,48 and with the severity of behavioral symptoms.47
The search for modifier genes affecting the phenotype has been carried out using the candidate genes strategy. Because high impact clinical manifestations in FXS are related with neurologic phenotypes, the studied candidate genes are involved in CNS development and the appearance of seizures (BNDF)56,6062 and associated with mood and aggression (5-HTTLPR, MAOA-VNTR y COMT).54,55 Recent research has been done with small groups of patients and there are no conclusive results about the importance of these variants in modifier genes.
Scientific and clinical evidence about molecular causes of variable expressivity in FXS is growing quickly. It is evident that aspects of the mutation type in FMR1 and the behavior of the CGG repeat tract are relevant in the presentation of the condition. Research about modifier genes is still emerging. There are important limitations such as sample size and comparability of different studies, mainly due to smaller groups of selected patients and the use of different tools for measuring the phenotypes.
Independent cohorts of patients with FXS across different continents have shown evidence that mosaicism, FMR1 mRNA or FMRP quantification are associated with the severity of the phenotype. However, this information cannot currently be used effectively in the integral management of patients. When intervention strategies become available in order to prevent the development of FXTAS, or when certain molecules can regulate levels of FMRP expression to measure FMR1 mRNA and FMRP, they could be crucial for selecting patients and identifying the best therapeutic intervention.
In clinical trials there is an important window of opportunity. Identifying mosaicism, measuring transcription/translation activity of FMR1 and stratifying patients by modifier genotypes29,65 will permit the identification of subgroups of patients with greater potential to respond to specific treatments.

‘Star Wars: The Bad Batch’ Who Is Omega? Inside the Magic – Inside the Magic
Michelle Angs Omega joins the Star Wars universe in the latest Disney+ television series from Lucasfilm, Star Wars: The Bad Batch. With voice actor veteran, Dee Bradley Baker, back as the titular Bad Batch, Angs character is stirring up some big questions for Star Wars fans namely, who is Omega in The Bad Batch?
Here is your guide to the new female clone in the Star Wars universe.
The Bad Batch premiere launched on Star Wars Day (May 4) and tells the story of a group of defective, genetically modified clones called Clone Force 99, or the Bad Batch. Made up of five mutated clone troopers Hunter, Tech, Echo, Crosshair, and Wrecker the squad partakes in numerous mercenary missions on behalf of the Republic, and are quickly becoming some of the best characters in the galaxy.
Dave Filonis (Star Wars Rebels, Star Wars Resistance) new animated series crosses over the events of Star Wars: The Clone Wars and Star Wars: Episode III Revenge of the Sith (2005) in the time before the original trilogy began. The season began with a feature-length episode titled, Aftermath, highlighting the historic moment of the Galactic Empires rise to power. Despite The Bad Batch controversy early on, the new series seems to have already built its fandom like many of the other Star Wars spinoffs.
When Chancellor Palpatine executed Order 66, overriding the Clone Armys programming to turn on their Jedi generals, Clone Force 99 was seemingly unaffected due to their enhancements. Although, as time wore on, some of the squad members did succumb to the Order 66 protocol before being saved by their brothers.
Omega, like the member of Clone Force 99, is a genetically enhanced clone. Essentially made from the DNA of bounty hunter Jango Fett, Omegas existence at least at first was seemingly unknown, but as the series progresses more and more is coming to light about the new character.
In the ninth episode of The Bad Batch, Bounty Lost, Omega was revealed to be a direct replica of Jango Fett, at least in terms of genetics. Only one other clone has this same link the bounty hunter, Boba Fett.
Arguably the new Grogu of Star Wars, Omega was introduced as a wide-eyed child intent on seeking a more adventurous life. Raised under the guidance of the Kaminoans on Kamino, Omegas first appearance came when the elite soldiers of Clone Force 99 returned to Kamino following the execution of Order 66. She was the medical assistant to Nala Se.
Hunter had just saved the Padawan Caleb Dume Kanan Jarrus in Star Wars Rebels after the murder of Jedi Master Depa Billaba, and upon returning to Kamino stumbled upon Omega. When Admiral Tarkin arrived on Kamino, Omega bonded with Hunter and the rest of Clone Force 99 before escaping the planet with them after Crosshairs chip activated, making him turn on his squad.
Many theories point to Omega being Force-sensitive. Her skill targeting a weapon in the premiere episode of the Star Wars animation, and more recently her ability to win every opponent at a game of dejarik, suggests there may be more than meets the eye with this honorary Bad Batch member.
What Star Wars fans do know, however, is that Omega is the daughter of Jango Fett and sister to Boba Fett. In Bounty Lost, after a near-death situation with the notorious Cad Bane and Fennec Shand, Tech revealed that Omegas genetic makeup is a direct replication of Jango Fetts. While the clone trooper armys genetics were slightly modified to grow quicker, Omega and Boba Fett were left completely untouched.
While Star Wars fans dont know much else other than this familial connection to two of the galaxys most notorious bounty hunters, her relationship to Boba Fett provides the most interesting detail, and not just for Filonis The Bad Batch. With only six episodes left of the first season, her backstory could point to the animated reprisal of Boba Fett or likewise the live-action debut of Omega in a Star Wars series down the line like Robert Rodriguezs The Book of Boba Fett.
Back to The Bad Batch though, we know the Kaminoans have hired bounty hunters to capture and protect Omega reasons unknown so her existence in the animated series suggests that trouble isnt far away for Clone Force 99.
As well as discovering what she is, Omega is slowly building a life outside of Kamino. Still under the shadow of those who made her, Omegas burgeoning connection to the members of the Bad Batch is how she seems to be writing her own history. The character is always one to dive into adventure, and even though this causes despair for Hunter and the gang, she is proving herself to be a valuable part of this formidable crew.
From helping in the mission on Corellia to find and secure a tactical droid to being present for the removal of the clones inhibitor chips on Bracca, Omegas Star Wars story has only just begun.
Omega is sharp-minded and headstrong. Sometimes a little nave, the character often heads into trouble with the right intentions but not the military skill to back it up. However, her way to find good in everyone as well as passing no judgments on what Clone Force 99 has had to do to stay alive makes her one of the galaxys warmest hearts.
Omegas personality has been shaped by those around her. The individual members of the unique squad, all of which have their own personalities seem to have rubbed off on the young clone. It is in her difference now to when she first met Clone Force 99, that fans can get an idea of how sheltered her life was back on Kamino. Much like how Grogu was in hiding for so long in The Mandalorian, Omegas entry into the big wide galaxy is a point of much character exploration.
From the Bad Batch, she learned about teamwork and survival, and even from characters like Cid (Rhea Perlman) has Omega developed new traits for this example, it seems Cids abrupt nature and aloofness has given Omega some new street smarts if her dejarik winning streak is anything to go by.
While Omega is the one Clone Force 99 protects most of the time, her calmness and quality to not see everything from a military perspective has aided the group on many occasions. Her competitive kinship with Rafa and Trace Martez on Corellia helped bring the sisters and the Bad Batch together to battle the army of police droids.
Omegas caring nature and inability to leave those she loves also highlight how the young clone is adding something new to the squad. Even after Wrecker set out to kill her after his inhibitor chip activated, Omega stayed by his side following the chip removal surgery and wouldnt rest until her squadmate woke up.
Omega has learned much since joining Clone Force 99. On Bracca, Wrecker taught her how to disarm explosives while on Ord Mantell, she acquired a Zygerrian energy bow. Although at first a novice in combat, Omega has quickly learned new skills in order to survive the attacks of Crosshair and the Galactic Empire as well as the relentless confrontations with the galaxys most nefarious bounty hunters.
Omega picked up her energy bow on Ord Mantell and has become an adept user at handling the weapon, although she still needs much practice to use it confidently. As StarWars.com describes:
Firing sizzling laser bolts instead of arrows, a Zygerrian energy bow is a formidable weapon in a firefight if you have a sharp eye and strong arms to lend the weapon unwavering accuracy.
It is perhaps the mystery surrounding the possibility of Omega being Force-sensitive that is most interesting in her skillset. Some might say its beginners luck or youthful charm, but the way she successfully aimed, possibly the first weapon she has ever wielded, in the premiere episode or managed to win numerous back-to-back games of dejarik, alludes to the fact that Omega may not be any regular clone.
Whether she is connected to the Force or not, Omegas skills at negotiating with her team members and other allies, as well as her ability to quickly pick up military talents make her more than suitable to take up the opening Crosshair left in Clone Force 99 and become one of the new rebels of the galaxy.
With more yet to discover, Omega is perhaps one of Star Wars most interesting new characters, and with many more upcoming projects, fans might not have to wait long for some answers.

Hair: Types and care instructions – Medical News Today
There are many different types of hair, including straight, curly, wavy, and coily.
Depending on a persons hair type, they may need to follow different care instructions.
This article will provide some general information about hair types and detail some specific care instructions.
Hair type typically refers to the shape of a persons hair. Hair can be straight, wavy, curly, or coily.
According to one 2020 article, hair consists of two structures: the strand of hair itself, or the hair shaft, and the hair follicle.
The hair shaft consists of different layers, including the cortex, the surrounding cells, and, in thicker hair, a central medulla.
A 2017 study notes that the shape of the hair follicle determines the shape of a persons hair. For example, the hair follicles for curly hair are in the shape of an S.
Genetic factors play a role in deciding the shape of a persons hair follicle.
Learn more about what determines hair shape here.
Hair shape refers to the degree of curliness of a persons hair.
One review article notes that different researchers have used different hair shape categorization systems in their research about hair. For example, some have used use labels such as:
Some hairstylists like to distinguish hair shapes into four categories. However, scientists do not use this categorization system in medicine or scientific research.
Hairstylists use the following categorization system:
Hair density refers to the number of hairs that a person has on their head. The more hairs a person has, the higher that persons hair density.
Hair structure refers to the thickness of the strands of hair. A persons hair can be:
According to the World Trichology Society (WTS), hair thickness varies depending on the person. Some people have finer hairs than others. The WTS also notes that the hair fibers become shorter and finer as a person ages.
Hair porosity is a measure of the amount of moisture that a persons hair can absorb.
Hair porosity depends on how many gaps or tears are present in the cuticle layer. The cuticle is the outer layer of the hair, which protects it from wear and tear.
According to one 2015 article, hair is naturally porous. However, hair that has sustained damaged due to bleaching or chemical treatments is more porous than untreated hair.
People may find it helpful to avoid strong chemical and high heat treatments to let their hair recover.
According to the American Academy of Dermatology (AAD), people can try the following when caring for their hair:
People should select their shampoo and conditioner based on their hair type.
If possible, they should try to limit:
There is some evidence to suggest that straight hair carries sebum more easily than curly hair. Sebum is a waxy, oily substance that a persons skin produces. This means that people with straight hair may be more likely to get oily hair than those with curlier hair.
For this reason, people with straighter hair may wish to avoid the excessive use of certain hair products. These include:
People with straight hair may also wish to wash their hair more frequently.
According to a 2015 article, a person with straight hair may need to use a more gentle approach to caring for their hair. This may involve:
Over-brushing can damage curl definition. Therefore, people with curly hair may need to experiment to find the right amount of brushing for their hair.
Some other care tips for curly hair include:
Some people may also wish to use hair mousses and gels that are intended for curly hair to maintain curl definition.
The AAD suggests the following tips for Black hair:
Additionally, people may wish to take care when using weaves or extensions. To prevent hair damage, they may wish to try:
Tight hairstyles can also lead to traction alopecia, which results in hair loss. People may wish to consider giving the hair a break after 23 months of wearing a weave or extension.
Learn more about Black hair care tips here.
People with thick hair may find it helpful to use denser hair products, such as:
Additionally, people with greater hair density may find it beneficial to use brushes that are designed for thick hair. These brushes have fewer spokes than others, which helps people remove knots without breaking the hairs.
There is anecdotal evidence to suggest that denser hair products, such as oils and butters, can weigh down thinner hair. For this reason, people with thin hair may wish to avoid these products.
People with thinner hairs may also benefit from:
The WTS notes that people shed approximately 50150 hairs per day. This can occur through hair washing, brushing, and combing. However, some people lose more hair than they can grow.
This can happen for various reasons. One common cause is androgenetic alopecia. This is a genetically predetermined condition that affects around 50% of people. In males, hair loss occurs at the temples and the top of the head. In females, hair loss can affect the crown.
Hair loss can also occur in females due to other health conditions, including:
A person should contact a doctor if they:
Some anecdotal evidence suggests that people can use certain shampoos, essential oils, and dietary supplements to thicken the hair. However, there is no scientific evidence to prove that hair care can prevent thinning hair.
That said, a person can take measures to help prevent some causes of hair loss, such as traction alopecia.
Learn more about stopping hair loss here.
Everyones hair is slightly different. A persons hair can be straight, curly, coily, or wavy, and each type benefits from different methods of care.
Although some hair loss is common, a person should contact a healthcare professional if they are concerned.

New laws hit the books in Mississippi on Thursday – Yall Politics
Check out what laws go into effect on July 1, 2021.
Dozens of Mississippi laws will go into effect on Thursday, July 1, 2021. Take a look at some of the most talked about bills of the 2021 session and how these new or revised laws could impact you.
Teacher Pay Raise
Probably one of the most talked about bill that passed from the House of Representatives was a raise for teachers and teaching assistants. HB 852, which had a nearly identical companion bill in the Senate, provided for a $1,000 raise for teachers at the start of the 2021-2022 school year and $1,100 for assistant teachers.
A teacher pay raise was on everyones mind entering the 2021 session and COVID-19 made it particularly important to lawmakers to see these funds diverted to teachers. In total, the raise made up an additional $50 million to education in the FY2022 budget.
Occupational Licensing Recognition
Workers in Mississippi and those who would like to come to the state but are licensed in other states, just got a helping hand. HB 1263, authored by Rep. Becky Currie, instated the Universal Recognition of Occupational Licensing Act. This bill allows individuals who work in other states and have a license that is in good standing with that agency to transfer for work to Mississippi with no additional loopholes.
RELATED: Governor Reeves on Universal Occupational Licensing Act: Mississippi is open for business
Just days before going into law, Governor Tate Reeves commented that this bill would allow workforce development to continue and labor shortages from the pandemic to decrease. He also said that it will reduce the red tape many professionals have to go through in order to work in Mississippi. That will include teachers coming from out of state to work here.
Election Qualifying
Planning to run for office in Mississippi? Well, take note of this bill lawmakers passed this session. HB 1048 effectively changes the qualification deadline to February 1 for some statewide, state district, county and county district offices.
Previously the deadline was not until March 1. This will bump the decision up for candidates considering a run for elected office by one month.
Appropriations bills
Mississippis budget was set during the 2021 session. The bills that pertain to appropriations for state agencies and such will all go into effect July 1, 2021. This marks the start of a new fiscal year in the state.
You can read more of those bills from the Senate and House here.
Alcohol Delivery
Many Mississippians have been pushing for more accessible ways to get their alcohol. The Legislature listened with HB 1135. This bill will allow the delivery of a particular wine, spirit or beer from a licensed retailer to a consumer. The retailer must also have a delivery service permit to participate in this service.
Those delivering can be current employees or contracted individuals who are at least 21 years old and receive proper training consistent with current programs. To place an order, you must be at least 21 years old.
Executive Sessions for Public Bodies
Speaker of the House Philip Gunn authored a bill, HB 1323, that will allow any public body to enter into executive session in order to develop a strategic plan to combat, eliminate, reduce or respond to human trafficking or the commercial sexual exploitation of children.
The reason these meetings would be necessary is to address a particular trafficking issue and attempt to provide an immediate solution.
MAEP Calculations
Over in the Senate, many lawmakers set their sights on improving education as well as helping the Mississippi Department of Education operate in unprecedented times.
SB 2149, which was authored by Sen. Dennis DeBar, provided that typical daily attendance rolls would not count against schools from the 2020-2021 school year.
Mississippis MAEP funding formula is calculated in part by daily attendance. Due to the unprecedented nature of the pandemic and virtual learning, daily attendance was unpredictable and, for many schools, impossible in-person during portions of the last year.
Teacher License Reciprocity
Similar to the removal of red tape for all occupational licensing, SB 2267 will allow reciprocity for teachers.
This bill will apply to any teacher coming from another state who already possess a teacher license and can pass a background check. Under the law, the Department of Education can grant a one-year extension to June 2022 to allow for that teacher to meet requirements in Mississippi.
The bill also implements the creation of a licensing and certification committee that will assist in streamlining the process for teacher certification in the state.
Earned Parole Eligibility
Possibly one of the most talked about pieces of legislation in general this year centered around the criminal justice system in Mississippi. SB 2795, or the Earned Parole Eligibility Act, was offered by Sen. Juan Barnett. He brought forward a similar bill in 2020 but it was vetoed by Governor Reeves.
Barnett said he took those critiques and perfected the language in order to have an agreement.
The Earned Parole Eligibility Act allows for particular non-violent, and some violent offenders, to be eligible for parole after a certain amount of their sentence has been served. The hesitation in 2020 centered around murderers being considered in the eligibility category, a move Barnet said was removed in the 2021 bill.
RELATED: Senate passes Mississippi Earned Parole Eligibility Act
Those not eligible include sex offenders, human traffickers, murderers, capitol, and habitual offenders. It is important to note that the bill does not grant any offenders parole; it only allows the possibility of parole in the event the individual has met the proper criteria for consideration.
The bill passed in both chambers and was later signed into law by Governor Reeves.
Medicaid Tech Bill
Every three years lawmakers are tasked with reconfiguring the guidelines for the Mississippi Division of Medicaid. This year it almost looked as if lawmakers would leave the 2021 session without a Medicaid Tech bill. However, at the final hour they were able to come to an agreement on the program with SB 2799.
RELATED: Medicaid will live on in the Governors office and with a budget
Though some attempts were made to remove the Division of Medicaid from under the Governors office, it remained housed there in the 2021 legislation. But the House did remove language that would have provided 12 months of postpartum care for mothers who receive the benefits.
Sen. Kevin Blackwell, Chairman of Medicaid, said the final bill included a 5% reimbursement for some providers, restored crossover claims for hospitals, nursing home and immediate care facility reimbursement days, and provided an additional 5% bump for dentists in 2022-2024 to cover preventative services.
RELATED: Senate passes bill to increase TANF benefits for Mississippians
Dept. of Public Safety
Many changes were made in regard to law enforcement and the Department of Public Safety. Perhaps the largest of note was the transfer of the Capitol Police from the Department of Finance and Administration to the Department of Public Safety. The law came by way of SB 2434.
The duties and abilities of the Capitol Police did not change with the bill, only the overseeing agency. The bill was offered by Sen. Brice Wiggins, Sen. Angela Hill and Sen. John Horhn.
Capitol Police monitor the Capitol Complex in Jackson.
Mississippi Fairness Act
Mississippi gained national attention with the passage of SB 2536, entitled the Fairness Act. The legislation, offered by Sen. Angela Hill, would prevent biologically male individuals from competing in female sports. This law will apply to K-12 schools as well as institutions of higher learning.
When defending her bill to those who claimed it was non-inclusive to transgendered athletes, Hill said those who were born physically a male have an advantage over female athletes simply due to genetics.

The bill was up in the air until the last minutes of the session when it was passed. Sen. Hill said the legislation was necessary in order to protect girls sports in the state under the current federal position toward transgendered persons competing among athletes that do not share their at-birth genetic makeup.
Name, Image, Likeness
Another bill that could impact Mississippi athletes is SB 2313. This bill will allow Mississippi collegiate athletes to receive compensation if their image, name or likeness is used in advertising.

Mississippi lawmakers believe passing this legislation will keep Mississippi schools competitive in the event the U.S. Supreme Court rules in current court cases to allow for the compensation.
Weight Limits
Senator Jennifer Branning presented SB 2825, the Mississippi Infrastructure Act of 2021 which tackled several road, bridge and transportation issues the state faces.
Probably the most considerable change was that of the harvest weight limits being raised from 84,000 pounds to 88,000 pounds. The bill goes into effect July 1, 2021, but the harvest permit increase does not take effect until July 1, 2023. These weight limits would only apply to commercial truckers carrying a harvest permit.
The bill was argued by many in the Senate as it moved through the process.

PATHWAY to Northern PROFITABILITY with Seifert Belmont Reds – Queensland Country Life
This article is branded content for Seifert Belmont Reds
Profit-making genetics are readily apparent in the 90 bulls and 10 PTIC heifers' that husband and wife team Ian Stark and Jeanne Seifert, have selected for their third annual Seifert Belmont Reds Sale.
Seifert Belmont Reds is the largest breeder of purebred registered Breedplan recorded Belmont Reds in Australia. Their aggregation of five properties totals approximately 10,000ha and is a mix of ticky and clean country from marginal iron bark breeder country to brigalow backgrounding country.
Mrs Seifert is particularly proud of their females who continue to naturally rebreed, even on the back of two of the driest years on record.
"Our genetics are produced from a tough, unpampered cow herd where females are managed under a single sire mating program, using Belmont Red bulls at 1 per cent - 2 per cent, for a nine or a twelve-week joining period.
"Our cattle are never ever treated for tick or fly, are rarely handled, and every female must wean a calf every year, off native pasture, without any special care," she said.
"Under this regime and dry years, our wet cows and heifers returned from 93.2 per cent to 98.5 per cent pregnancy rates this year."
Early puberty bulls are also used from 14 months old to produce higher fertility daughters and sons. These stringent 'survival of the fittest' breeding principles, ensure that the young bulls catalogued for the 2021 sale will provide valuable heritable traits including phenomenal fertility, excellent growth and carcase attributes, genuine docility, and the highest levels of environmental adaptation.
Of the 90 bulls, 44 are Homozygous Polls (PP) and offer phenomenal fertility, truetropical adaptation and parasite resistance, with muscling and marbling.
"To top it off , 44 bulls of the 90 bulls are homozygous (PP) polls, and an impressive 73 per cent of them are at or above the 50th percentile for the Breedplan export $index."
Mr Stark said their emphasis on real fitness for purpose, and their ability to reliably meet volume demand, plus JBAS 7 status, ensures Seifert Belmont Reds can sell Australia-wide including into the Northern Territory and Western Australia.
"The reputation for our bulls to deliver consistent lines of calves, stems from many decades of breeding, where our pedigrees can be traced back to the original CSIRO Africander cross breeding trials of 1954," Mr Stark said.
"I'm especially pleased with the progress our herd has made with respect to type, muscling, and eye muscle area.
"IVF (invitro fertilization), ET (embryo transfer), AI (artificial insemination) and cloning are used to create optimum genetic combinations and accelerate genetic progress."
The demand for tropically adapted Bos Taurus Seifert Belmont Red genetics is emphasised by their exportation to Papua New Guinea, New Caledonia, the Philippines, and South America.
In 2020 the stud also established a satellite purebred Belmont Red herd with partners in Paraguay.
"Our focus on personal and professional integrity, combined with trustworthy data, provides peace of mind to our buyers," he said.
"We have every confidence in this draft, and we're sure they will make a valuable contribution to your herd and your profitability."

PATHWAY to Northern PROFITABILITY with Seifert Belmont Reds - Queensland Country Life
In Memoriam: Jean Wilson, M.D., made scientific discoveries that led to effective prostate treatments, insights into sexual differentiation – UT…
DALLAS June 21, 2021 Jean D. Wilson, M.D., an internationally known endocrinologist whose scientific discoveries led to profound insights into the mechanisms underlying sexual differentiation and led to now widely used treatments for prostate disease, died June 13. He was 88.
Wilson, seen here in 1962, graduated from UTSouthwestern Medical School in 1955 and joined the faculty in 1960, where he began his studies of testosterone.
Wilson, professor emeritus of internal medicine at UTSouthwestern, was largely responsible for current understanding of the mechanisms by which steroid hormones induce male sexual differentiation. He also was instrumental in identifying the scientific underpinnings of a widely prescribed class of drugs known as 5-alpha-reductase inhibitors which include finasteride (Proscar, Propecia) and dutasteride (Avodart) to treat enlarged prostate and balding in men.
Wilsons discovery of 5-alpha-reductase and the identification of dihydrotestosterone as the primary hormone associated with the growth of the prostate transformed our understanding of prostate gland growth and paved the way for new effective treatment of prostate disease, says Daniel K. Podolsky, M.D., president of UTSouthwestern. His findings led to the first medical therapy for benign prostatic hyperplasia, and also provided the basis for understanding of the mechanism underlying the differentiation of male and female genital development. His legacy will be found in the legions of patients who have benefited from the therapy made possible by his discoveries.
Wilson, seen in 1978, was a popular and highly sought-after attending physician on the wards of Parkland Memorial Hospital, valued for his vast expertise in endocrinology and medicine in general.
Jean Wilson was one of the most critical and helpful sources of information concerning the development of two important drugs we were developing at Merck the statins, for control of LDL cholesterol, and Proscar, for treatment of benign prostate enlargement. Wilson was always available to wrestle with problems that often arise in drug development. I needed expert friends in those early days, and probably still do, says P. Roy Vagelos, M.D., former chairman, president, and chief executive officer of Merck & Co. and now chair of the board of Regeneron Pharmaceuticals.
Wilsons research included the study of cholesterol metabolism and steroid hormone action. The UTSouthwestern Medical School graduate and former National Institutes of Health (NIH) researcher earned international prominence for his investigations of testosterone including its formation from cholesterol as well as its metabolism and action. His efforts elucidated disorders resulting from genetic defects that lead to disruption in sex hormone biosynthesis with corresponding alteration in development.
Collaborations at UTSouthwestern with David Russell, Ph.D., professor of molecular genetics, led to the cloning of the 5-alpha-reductase (5AR) gene, development of animal models for 5AR deficiency, and eventually the finding that a 5AR inhibitor blocked prostate growth, which resulted in clinical trials led by Claus Roehrborn, M.D., chair of urology. The human androgen receptor later was cloned in 1989, allowing Wilson and colleagues to identify the receptor as a transcription factor that could regulate both the receptor and 5AR expression in prostate cancer. Other scientists at UTSouthwestern expanded upon his research, identifying androgen involvement in virtually all aspects of prostate development, alternate mechanisms of androgen synthesis, and other forms of androgens related to castrate-resistant prostate cancer.
Among his numerous awards, Wilson received the Kober Medal from the Association of American Physicians (1999); the Fred Conrad Koch Award from The Endocrine Society (1993); Gregory Pincus Award from the Worcester Foundation for Experimental Biology (1992); Henry Dale Medal from the Society for Endocrinology (1991); Amory Prize from the American Academy of Arts and Sciences (1977); and the Eugene Fuller Award from the American Urological Association. He was elected as a member of the American Academy of Arts and Sciences (1982), the National Academy of Sciences (1983), and the National Academy of Medicine (1994) as well as the American Philosophical Society and served as president of the Endocrine Society, the American Society for Clinical Investigation, and the Association of American Physicians.
Wilson, seen in 1992, was elected as a member of the American Academy of Arts and Sciences (1982), the National Academy of Sciences (1983), and the National Academy of Medicine (1994).
Wilson, who had held the Charles Cameron Sprague Distinguished Chair of Biomedical Research, was known as a collaborative colleague and empathetic adviser to students and fellows. His approach with students and trainees was threefold find out what they want to do, encourage them to do it, and develop pathways to fulfill their goals, he said in an interview with The Journal of Clinical Investigation. He also noted that some of the most difficult students to counsel turned out to be late bloomers who really were worth an investment of time and effort.
At UTSouthwestern, he served as the first director of the Medical Scientist Training Program, and it was recently announced that the Physician Scientist Training Program in Internal Medicine would be known as the Jean Wilson Society. The Jean D. Wilson Center for Biomedical Research and The Jean D. Wilson, M.D. Award, which honor excellence in scientific research mentorship, are named in his honor. The center was established with support from Dr. Wilson and his sister, the late Dr. Margaret Sitton, to promote research in endocrinology, developmental biology, and genetics, along with the J.D. and Maggie E. Wilson Distinguished Chair in Biomedical Research. In addition, he served among editors of two landmark medical textbooks Williams Textbook of Endocrinology and Harrisons Principles of Internal Medicine and as editor for The Journal of Clinical Investigation, among other journals. He authored The Memoir of a Fortunate Man, which chronicles his life growing up in the Texas Panhandle through his rise to pioneering academic physician and researcher.
Jean was a popular and highly sought-after attending physician on the wards of Parkland Memorial Hospital, valued for his vast expertise in endocrinology and medicine in general, say Nobel Laureates Joseph Goldstein, M.D, chair of molecular genetics, and Michael Brown, M.D., director of the Erik Jonsson Center for Research in Molecular Genetics and Human Disease. He founded a diabetic foot clinic at Parkland and spent hours each week clipping toenails and treating ulcers on the feet of elderly diabetic patients. After long days on the wards, he would retire to his modest laboratory where he would spend half the night meticulously dissecting rabbit fetuses. Often, when we were just starting our careers, we would sit by his side while he dissected, receiving sage advice about our careers as physician-scientists and life in general. Later, he extended his fatherly role to generations of M.D./Ph.D. students when he became the founding director of our M.D./Ph.D. program.
He had a rich life outside of the Medical Center as well. An avid opera buff, Wilson collected antique gramophones that could play every type of recording that had ever been produced. His extensive collection of 3,500 old 78-rpm operatic recordings included a 1917 disc of Enrico Caruso singing songs of Irving Berlin the only record that Caruso ever recorded in English, they note.

He took memorable trips to places like the North Pole, Antarctica, the Galapagos Islands, and the Easter Islands. He often incorporated science into his trips, visiting the Kangaroo Island in Australia to study sexual development in wallabies, and to Kenya to biopsy the phallus of the spotted hyena. Fearless in the pursuit of knowledge, he performed a rectal examination on a lion to estimate the size of the prostate, Goldstein and Brown say. A dedicated bird watcher, he traveled the world to many exotic places, hoping to spot that rare bird. But in the end, the rarest of that rare bird was Jean Wilson himself.
Born in Wellington, Texas, in 1932, Wilson obtained an undergraduate degree in chemistry from UT Austin and graduated from UTSouthwestern Medical School in 1955. As a student, he studied the control of urinary acid secretion by adrenal hormones, and as a resident, he investigated cholesterol metabolism. After residency, he spent two years at the NIH, where he studied ethanolamine biosynthesis. He joined the UTSouthwestern faculty in 1960 where he began his studies of testosterone, and worked in 1970 at Cambridge University. In all, he spent 60 years at UTSouthwestern and was named professor emeritus of UTSouthwesterns storied internal medicine department in 2011.
Jean Wilson leaves us with a remarkable legacy a quintessential physician-scientist whose scholarship both inspires and continues to serve as a foundation for new advances, says Podolsky, also professor of internal medicine.
In a career spanning six decades at UTSouthwestern, Dr. Jean Wilsons discoveries included:
Cholesterol metabolism
Dr. Wilson developed methods for quantifying cholesterol synthesis, absorption, degradation, and excretion in lab animals. Together, these analytical methods served as tools for understanding the feedback control of cholesterol synthesis and turnover. In addition, Dr. Wilson demonstrated that plasma cholesterol is synthesized in the intestinal wall and liver, findings that helped researchers define the contributions of diet and endogenous synthesis to cholesterol turnover in humans and other primates.
Male androgens
Concurrently, Dr. Wilson studied the action of male androgens, focusing on testosterone and its metabolite, dihydrotestosterone. Starting with a collaboration with his postdoctoral fellow, Nicholas Bruchovsky, in 1966, the researchers discovered that testosterone is converted inside prostate cells into dihydrotestosterone, a more potent androgen that is responsible for most of male sexual maturation and male sexual function. Dr. Wilson and his colleagues later showed that mutations that impair either the synthesis of testosterone, the conversion of testosterone to dihydrotestosterone, or the function of this metabolites receptor protein are the most common cause of birth defects associated with incomplete development of the male urogenital tract, affecting about four in every 1,000 boys. Cloning these responsible genes eventually allowed researchers to identify asymptomatic carriers of these mutations.
Dihydrotestosterone
Dr. Wilson also discovered that excess dihydrotestosterone is responsible for benign prostatic hyperplasia (BPH), or prostate enlargement, a condition that affects about 210 million men worldwide. Dihydrotestosterone is responsible for prostate growth in all male mammals, but in humans and dogs, prostate growth continues throughout life. Wilson and his colleagues showed that local excess of this potent androgen leads to prostate overgrowth. By curbing its production by inhibiting 5a-reductase, the enzyme that converts testosterone to dihydrotestosterone, they were able to prevent BPH in dog models of this condition. These findings have been developed into multiple 5a-reductase-inhibiting pharmaceuticals to treat this condition in human patients.

Aduhelm Is A New Option to Treat Alzheimer Disease – Pharmacy Times
About 5.8 million Americans in 2020 were living with the disease, according to CDC data.2
Estimates show that this number will nearly triple to about 14 million people by the year 2060. Although the disease occurs mostly in older individuals, symptoms sometimes also occur in younger patients.
AD is the sixth-leading cause of death in the United States and the third-leading cause of death for patients older than age 65 years.
The disease is named after physician Alois Alzheimer, MD, who in 1906 discovered changes in the brain of a female patient who had died of mental illness. This patient suffered from language problems, memory loss, and unusual behavior. While examining her brain, Alzheimer found a few abnormal clumps, also known as amyloid plaques, and tangled bundles of fibers called neurofibrillary tangles.
An early symptom of AD is forgetfulness. As the disease advances, the individual may develop more severe memory impairment and can become more debilitated, causing then to struggle with completing everyday tasks. Symptoms are typically noticed by close family members who interact with the individual frequently, and they may become severe to the point that the patients forget relationships and even sometimes the names of loved relatives. Changes in the brains of these patients can also affect their behavior and mood and include aggressiveness, delusions, depression, irritability, more distrust of others, and social withdrawal.
Causes of AD may be related to brain proteins that fail to function normally, causing neurons to not be able to perform their duties. This impairment can be caused by environment, genetics, and lifestyle. The damage starts earlier than the point that the symptoms start to show, and in late stages, the brain shrinks significantly from its normal size.
The proteins involved include beta-amyloid plaques, which when clumped together cause toxic effects on neurons and disrupt the cell-to-cell connection. Meanwhile, Tau proteins help carry essential minerals and nutrients to the brain, and in patients with AD, these proteins change shape and become entangled. This disrupts the nutrient transport system, affecting brain cell function.
Genetics play a role in a patient developing AD, specifically for those with first-degree relatives diagnosed with the disease. Gender also plays a role, with women diagnosed more often than men, though this may also be related to the fact that women tend to live longer.1
One genetic factor known to cause the disease is Apolipoprotein E gene, which with the e4 variation, increases the risk of AD exponentially. Additionally, patients with Down syndrome are more likely to develop AD than others. This is likely related to 3 copies of the chromosome 21, which connect with the creation of beta-amyloid.
Diagnosing AD may include neuropsychological testing and brain imaging, using amyloid positron emission tomography (PET), computer tomography, magnetic resonance imaging, PET scan, or Tau PET imaging.
Medications used to great AD include those that help with memory symptoms and treat cognitive changes. Two major types of the drugs available on the market for these patients include cholinesterase inhibitors and memantine. Cholinesterase inhibitors may help treat agitation and depression and commonly include donepezil (Aricept), galantamine (Razadyne), and rivastigmine (Exelon). Memantine (Namenda) and the combination of memantine and donepezil (Namzaric) combine a cholinesterase inhibitor with memantine to help with medication compliance and help slow the progression of disease symptoms.
On June 8, 2021, the FDA approved aducanumab injection (Aduhelm), an amyloid beta-directed antibody indicated for the treatment of AD. Aduhelm comes in 2 dosages of 170mg/1.7ml and 300mg/3ml solution. The recommended dosage for this drug is 10mg/kg as an intravenous infusion for more than 60 minutes every 4 weeks.
Aduhelm provides new hope for patients diagnosed with AD to have more treatment options available to them after many years of waiting for an FDA approval. The future for research in this area is promising and holds the key to more discoveries, including a cure for AD.

‘Unfair Biological Athletic Advantage’, Maltese S&C Coach Weighs In On Trans Weightlifter Competing At The Olympics – Lovin Malta
Kiwi trans woman weightlifter Laurel Hubbard has reignited debates on transgender participation in sports following the announcement that she would be allowed to compete in the womens category at the Summer Olympics in Tokyo this year.
The landmark decision is the first since the International Olympic Committee modified its guidelines in 2015 to allow trans woman athletes to participate if they showed testosterone levels of less than 10 nanomoles per liter for at least one year prior to competition.
Needless to say, allowing Hubbard to participate in the womens weightlifting category has sparked both praise and criticism, with one side commending its inclusivity, while the other side draws attention to an uneven playing field created, with concerns that trans women may have an advantage over their peers and competitors due to their physical abilities.
Malta is equally divided on the subject, with some activists on one side of the fence and sports professionals on the other.
Laurel Hubbard is the first trans woman to compete in an Olympic Games
When you look at a female-born athlete at a high level, they are competing at around three nanomoles per liter of testosterone which already indicates that the level of testosterone of a female athlete is three times lower than that of a transgender woman that has undergone hormone replacement therapy, renowned strength and conditioning coach Nigel McCarthy told Lovin Malta.
Amongst the benefits of having higher testosterone levels are increased muscle mass, bone density, decreased fat percentage and recovery time.
Apart from the latter, performance does not reflect what happened the previous year but is an accumulation of years of building, he continued. The blood, hormones and cell production in your body are all signaled by previous years of training.
Despite having to undergo hormone replacement therapy, a body of research indicates that trans women are still at a biological advantage when compared to other female athletes, McCarthy argued.
Not all the advantages are diminished and still a large overwhelming benefit remains from being male years prior when it comes to biological advantages of strength and power, he said.
This is clearly shown by the results of transgender athletes when competing in female categories winning by large distances and not just the mere half a second or a centimeter.
In 2019, transgender athlete Rachel McKinnon set a world record time in sprint cycling with a timing of 11.649 seconds. Her opponent, Dawn Owrick, came in second with a time of 12.063.
Those on the other side of the fence argue that the decision to allow Hubbard to compete in the womens category of the Olympic Games promotes inclusivity and that it is skill, rather than genetics, that determines a champion.
Unfortunately, we think of sports as being fair which in reality is not, it is all a natural genetic lottery you do not choose to be tall, have higher testosterone levels or respond to training as well as others, McCarthy said.
While acknowledging that sports should be accessible to all, the S&C coach also believes in preserving the right of fairness for those who are also competing.
More studies need to be done to test baseline level before and after therapies for transgender athletes, he continued. There also needs to be a better understanding of the biological differences between males and females which determines athletic ability.
Hubbard will be competing in the womens 87kg weightlifting category. Though she has the backing of the New Zealand government and Olympic Committee, the decision on her participation hasnt been welcomed by some of her peers, including Belgian weightlifter Anna Vanbellinghen, who claimed that this particular situation is unfair to the sport and to the athletes.
As things stand, an out-of-proportion and unfair biological athletic advantage is occurring at the expense of born female athletes when competing against transgender athletes, McCarthy continued.
Hubbard had competed in mens weightlifting competitions prior to coming out as transgender in 2013.
The current total weightlifting record for men competing in the 89kg category is 387kg consisting of a combination of clean & jerk and snatch.
Meanwhile, the total female world record for athletes competing in the 87kg category stands at 294kg.
On a personal note, this should really be discussed by female athletes and not by myself or by any outsider not knowledgeable or impacted by the decisions, McCarthy said.
Females are having their hard work and opportunities lost to transgender athletes who evidently have an unfair athletic biological advantage, he ended.

Lions, More Tigers, and Bears, Oh My! Meet PDZA’s Newest Resident Tiger – southsoundmag.com
Meet Raja, the newest resident of the Point Defiance Zoo & Aquarium. The 2-year-old critically endangered Sumatran tiger was revealed to the public last weekend (June 19-20) and could hold the key to protecting the Sumatran tiger species.
Rajas definitely not in Kansas anymore, but Tacoma welcomes the tiger with open arms and the possibility he brings.
Raja moved from Topeka Zoo & Conservation Center to Point Defiance Zoo in an attempt to boost breeding and ensure the future survival of the big cat species. With roughly 400 remaining, zoos joined the Species Survival Plan for Sumatran tigers to protect the critically endangered species from disappearing entirely because of habitat loss, poaching, lack of prey, and tiger-human conflict. Point Defiance Zoo has become a leader in Sumatran tiger conservation efforts, along with a list of other endangered species.
We are proud to be part of the conservation community working to ensure this species is around for future generations, Dr. Karen Goodrowe Beck, the general curator and Species Survival Plan coordinator for all tiger species at the Association of Zoos & Aquariums, said in a press release.
Rajas valuable genetics are vital to the survival of his species, Dr. Goodrowe Beck said. In the future, Raja will likely father the cubs of the three female Sumatran tigers housed at the zoo: Kali, Kirana, and/or Indah.
Visit Raja in the Asian Forest Sanctuary section of Point Defiance Zoo and stay tuned for news of Sumatran tiger cubs in the future.

Female athletes at risk of bone fracture resistant to muscle injury : The Asahi Shimbun – Asahi Shimbun
Genetic factors appear to affect the risk posed to female athletesfor getting certain kinds of sport-related injuries, a new study suggests.
Scientists found that female athletes fortunate enough to be resistant to muscle dislocation are more prone to getting fatigue fractures.
The researchers said they discovered through their analysis that the genetic factors that help build tolerance against muscle fragmentation and fatigue fractures do not work at the same time.
The finding is expected to lead to the development of new methods for injury prevention based on patients genetic conditions.
However, that correlative relationship does not appear to exist in men.
Women have fewer proteins in their bones and muscles, and the differences come to the surface more easily, said Eri Miyamoto, an assistant professor of genetics at Juntendo University.
Miyamoto and her colleagues examined the genes of 1,667 male and female athletes primarily in their 20s and 30s. They compared their genetic makeup with their records of fatigue fractures, muscle dislocation and other kinds of myopathy, or muscle tissue problems.
The results revealed no fewer than 17.8 percent of women marked by a certain genetic composition had developed stress fractures, while the ratio of myopathy was as low as 9.9 percent for the group.
About 80 percent of the athletes had that genetic feature, which is associated with proteins that constitute bones and muscles.
Researchers found those athletes had lower bone density and more flexible muscles.
Women with another genetic element developed myopathy and fatigue fractures with a probability of 18.6 percent and 9.0 percent, respectively. This marked a sharp contrast to the results for the other group.
However, no significant differences in the development risks from the disorders were found among the male athletes, according to the study.
The teams findings were published in March in the online edition of the U.S. sports medical journal Medicine & Science in Sports & Exercise, available at: https://journals.lww.com/acsm-msse/Abstract/9000/Female_Athletes_Genetically_Susceptible_to_Fatigue.96070.aspx

Why vaccine side effects really happen, and when you should worry – National Geographic
Side effects can be a powerful deterrent stopping people from getting vaccinated. To address this issue, in 1991, a group of scientists in Minnesotaat the Department of Veterans Affairs and the Mayo Clinicdevised an experiment to see just how frequent these unpleasant reactions were.
The study involved more than 300 veterans over the age of 65 who were given either a flu shot followed two weeks later by a placebo injection of salt water, or a placebo shot followed two weeks later by the real vaccine.
When the researchers unblinded the study to see who received the vaccine versus the placebo, the side effects were split equally between the two groups, says Robert Jacobson, medical director for the population health science program at the Mayo Clinic. About five percent said they got sicker than they ever had been in their entire life, says Jacobson. Half of these people had received the placebo and yet they complained of the worst headaches, or worst fever, of their lives. The take-home message here, says Jacobson: Its easy to confuse an allergic reaction with nervousness or emotions or even stomach upsets from anxiety.
Recent studies show some side effects, even ones from the COVID-19 vaccines, arent due to the shots at all, but to our own fears. Weve seen this in the military, when young recruits, who think they can tolerate anything, faint when they get the injections, because their body overreacts, says Jacobson.
Its a lesson that may be useful to medical professionals, who can reassure patients that most side effects are normal and predictableand may not even be caused by the shot. Case in point, in studies of the Pfizer/BioNTech vaccine, 23 percent of people aged 16 to 55 who received the placebo complained of fatigue after their second jab, and 24 percent noted headaches.
Studies do suggest that up to seven out of ten people getting their second shot have some type of reaction. Some feel a soreness at the injection site on their arm. They may experience itching or hives, or a range of flu-like symptoms, such as chills and fever, headaches, or debilitating fatigue, that can leave them bedridden for a day or two. Still, its important to put these side effects in perspective, says Jacobson, because these are mild, temporary, and transient reactions that disappear within a few days.
In the case of the authorized COVID-19 vaccinesPfizer, Moderna, and Johnson & Johnsonall contain a genetic blueprint for manufacturing spike proteins, which sit on the surface of the coronavirus and enable it to infect human cells. When human cells receive these instructions, they churn out copies of spike protein. But since the cells make only a piece of the virus, and not the whole pathogen itself, we dont get sick. But while the foreign spike cant cause disease, it can activate a two-step immune responseexactly as it is supposed to do.
The immediate physical reaction to the COVID-19 vaccine is caused by the innate immune system. When a person receives a shot, a flurry of white blood cells called macrophages and neutrophils arrive at the injection site and begin producing chemicals called cytokines. This response triggers a wide range of symptoms, from inflammation and swelling at the injection site to fever, fatigue, and chills.
As a result, side effects are a natural reaction to vaccination. This responsecalled reactogenicitymeans the vaccines instigate a strong, initial immune response and trigger a wide range of symptoms. Out of about 3,600,000 vaccinated people who participated in a survey in February, approximately 70 percent reported pain at the injection site, 33 percent felt fatigued, 29 percent suffered headache, 22 percent had muscle pain, and 11 percent experienced chills and fever after their first shot of a COVID-19 vaccine. The symptoms were even more pronounced after the second dose. Still, the innate immune response is short-lived, lasting only a few days.
But not everyone experiences side effects after a COVID-19 vaccine. Some feel fine after both doses. Scientists dont really know why, says Sujan Shresta, an immunologist at the Center for Infectious Disease and Vaccine Research at the La Jolla Institute for Immunology, in California. But its not a surprise that each person mounts the immune response differently.
Several factors can contribute to this wide variation. Women, for example, typically have stronger immune reactions than men, which may be part of what makes them more prone to suffering from side effects from the shots.
We all have our own individualized immune system, says John Wherry, director of the institute for immunology at the University of Pennsylvania, in Philadelphia. Its almost like our own immune fingerprint thats driven by genetics, gender, diet, our environment, and even our life history, which are the things our immune system has been exposed to in the past and has been trained to respond to over the years.
Even if you dont have an unpleasant reaction, the vaccines are still doing their job, because the real work of the immune systemand of the vaccinestakes place during the second, or adaptive, phase of the immune response. During this phase, the spike protein generated via the vaccine trains the B-cells to produce antibodies that match the virus, and the T-cells to seek-and-destroy infected cells. But it takes days to weeks to provide this long-lasting protection against the virus.
This is also the reason why people often have more rigorous reactions to the second shot. Three weeks after the first shot, the immune system has already been primed, and the B-cells and T-cells are ready to fight. When the second shot is delivered, both the innate and adaptive systems respond.
Still, we dont really know if having a serious response to the vaccines is a measure of the strength of the immune system. We also dont know if it means that someone who doesnt have a strong innate response will be more vulnerable to COVID or more resistant. We really dont have any data in the field on thiswhether a person with strong side effects would have a more severe COVID infection and vice versa, says Wherry.
In a February study that looked at the data from the first 13.7 million COVID-19 vaccine recipients, the Centers for Disease Control and Prevention found that nearly 80 percent of the people reporting reactions were female, even though only 61.2 percent of the injections had been given to women. In a similar vein, the CDC reported that all anaphylactic reactions to the Moderna shot have been in women; 44 of the 47 people whove had these reactions to the Pfizer injection were female.
The majority of people who have experienced the severe blood clotting issues with the J & J vaccine, and also the AstraZeneca vaccine in Europe and the United Kingdom, have been women. There has been speculation about hormones playing a rolewhich is always the first culprit thats looked at when you see a major sex difference, says Penns Wherry.
Several other factors may also contribute to this gender imbalance. Women also seem to have a more robust immune system, both in their innate responses and in their adaptive immune reactions. Females mount a stronger antibody response than males but its a double-edged sword because this is why women have more auto immune disease than men, says Shresta of the La Jolla Institute for Immunology.
Other studies have shown that a womans response to half a dose of the influenza vaccine was the same as mens full dose, so females might not need full doses of the COVID-19 vaccines. We have this idea that one size fits all, but this may be part of whats contributing to the higher rate of reactions among women, says Rosemary Morgan, a scientist specializing in gender research at the Johns Hopkins Bloomberg School of Public Health. There is also a behavioral componentwomen are more likely to visit the doctor and to be more proactive about reporting unpleasant symptoms.
But side effects and adverse eventswhich often get conflatedare not the same, says Wherry. Side effects are pretty commonoccurring maybe 50 to 70 percent of the time. But adverse events are rare and unexpected, like the clotting disorders.
Immediately after injection, about two to five people per million experience anaphylaxis, a severe allergic reaction that causes a dramatic drop in blood pressure and difficulty breathing. But even this is easily treatable with an EpiPen and antihistamines, which is why everyone is asked to stick around for 15 minutes after their COVID-19 shots.
The blood clots associated with the Johnson & Johnson vaccines, that have occurred within six to 13 days of receiving the shot, can be dangerous and even life threatening. But the incidence is quite low; there are only 23 confirmed cases out of 8.4 million doses of the vaccine.
This is very rare, says Ofer Levy, director of the precision vaccines program at Boston Childrens Hospital and a professor of pediatrics at Harvard Medical School. The risk of getting COVID and possibly dying is much higher than getting blood clots from the vaccines.
There is some worry that there may be other adverse effects that have gone largely unreported.
The three COVID-19 vaccines that have been authorized in the United States have been tested on tens of thousands of people in clinical trials, and manufacturers were required to follow up with at least half the vaccine recipients for two months or more after they received both shots. But now that more than 116 million Americans have been fully vaccinated, rare side effects that dont show up in smaller human clinical trials can emergewhich is why surveillance systems are important.
Here in the U.S., we have a patchwork of systems: the Vaccine Adverse Event Reporting System (VAERS), the Vaccine Safety Datalink, and the CDCs new phone-based tracking program, v-safe.
All of these have limitations, including that someone has to suspect these health outcomes are related to vaccination and go to the trouble of filling out the form, says Katherine Yih, a biologist and epidemiologist at Harvard Medical School, specializing in infectious diseases, immunization, and vaccine safety monitoring. We have a vigorous surveillance system in place. But we cant be sure its picking up everything.
Whats more, these incidents only show correlation. In other words, if someone died or had a stroke after getting vaccinated, physicians dont know if it was triggered by the shot. Only further study can reveal that.
The swift identification of the rare blood clotting disorder related to the J & J vaccine was reassuring. Initially, six cases were reported, prompting the FDA and the CDC to temporarily halt its use. When the CDCs Advisory Committee on Immunization Practices met in late April to determine the vaccines fate, 15 cases had been detected out of seven million people who had the shot. The discovery of that association with the J & J vaccinewhich is very rareis a real demonstration of how good our safety program is, says the Mayo Clinics Jacobson. At this point in the pandemic, a risk of less than three per million should not enter into our calculus of how to proceed.
