SAN FRANCISCO — A bounty of 10 African penguin chicks has hatched in just over a year at a San Francisco science museum as part of an effort to conserve the endangered bird.

The penguins began hatching in November 2022, ending a four-year period without any new chicks, and continued through January of this year, the California Academy of Sciences announced Wednesday.

African penguins have dwindled to 9,000 breeding pairs in the wild, the academy said in a statement.

Threats such as overfishing, habitat degradation and oil spills have reduced colonies of the charismatic black-and-white birds, said Brenda Melton, director of animal care and well-being at the museum’s Steinhart Aquarium.

“Every chick we welcome strengthens the genetics and overall population of the species in human care,” she said.

Chicks spend their first three weeks with their penguin parents in a nest box. They then attend “fish school,” where they learn to swim on their own and eat fish provided by biologists. Once ready, they are introduced to the colony.

The 21 penguins at the museum in Golden Gate Park have distinct personalities and are identifiable by their flipper bands, according to the academy’s website.

Opal is the oldest and, at age 36, has perfected the ability to catch fish in mid-air. Her partner, Pete, is a messy eater and a flirt.

Partners Stanlee and Bernie, who both like to bray, produced four of the 10 chicks, including Fyn, named for a type of vegetation found on the southern tip of Africa. Fyn is the youngest on exhibit and older sister to Nelson and Alice, both hatched in November.

Fyn often runs up to biologists when they enter the habitat and shakes her head at them — typical courtship behavior that chicks and juveniles commonly display toward people who have cared for them since hatching.

The youngest chick hatched January 12, and its sex has not yet been determined.

African penguins can live to be 27 years old in the wild, and longer in captivity.

vancouver, british columbia — The Canadian government is delaying access to medically assisted death for people with mental illness.

Those suffering from mental illness were supposed to be able to access Medical Assistance in Dying — also known as MAID — starting March 17. The recent announcement by the government of Canadian Prime Minister Justin Trudeau was the second delay after original legislation authorizing the practice passed in 2021.

The delay came in response to a recommendation by a majority of the members of a committee made up of senators and members of Parliament.

One of the most high-profile proponents of MAID is British Columbia-based lawyer Chris Considine. In the mid-1990s, he represented Sue Rodriguez, who was dying from amyotrophic lateral sclerosis, commonly known as ALS.

Their bid for approval of a medically assisted death was rejected at the time by the Supreme Court of Canada. But a law passed in 2016 legalized euthanasia for individuals with terminal conditions. From then until 2022, more than 45,000 people chose to die.

Considine said he was in favor of postponing an extension of the law to those with mental illness because depression can have numerous reasons, such as poor housing or job prospects. He pointed to the difficulty many people face in getting timely psychiatric help.

He said pressure for the delay came from numerous parts of Canadian society.

“I think that there was pressure from a number of sources, including provincial governments in Canada, a number of them who felt that they could not provide the funding nor the resources for persons who are depressed to receive access to health care professionals, such as psychologists and psychiatrists,” he said.

Pamela Wallin, a former journalist, was one of three senators in the minority on the parliamentary committee. She told VOA that medical experts say they are ready, but not the politicians. She feels continuing the delay is cruel.

“But if you have a mental illness, no, no, no. We’ve already made you work and wait for three years on this, and we promised you it would be ready,” she said. “But now we’re going to make you wait another three years while we think about it some more. I’m just appalled that we would do this to people who are suffering in ways that many of us can’t even understand.”

Sally Thorne, a professor emeritus of nursing at the University of British Columbia, said if mentally ill people wish to apply for medical assistance in their deaths, they have to meet all the current requirements for people with physical ailments whose deaths are not reasonably foreseeable but who have chronic and life-limiting conditions.

These requirements include evaluations by multiple doctors, including a specialist in a patient’s particular condition, being offered other methods of treatment, and a 90-day waiting period.

Thorne said she was not worried about the argument that those with mental disorders lack the ability to give consent.

“Because such people do, in our society, buy a house or sign consent for cardiac surgery or something like that. We do as a society understand that there’s a difference between having a mental illness and having the capacity to provide informed consent,” she said.

Thorne said it was an interesting paradox that those with mental illness who also have qualifying physical conditions can legally access medical assistance in dying.

Arthur Schafer, the founding director of the Centre for Professional and Applied Ethics at the University of Manitoba, said the pressure for the latest pause was entirely expected and was misguided.

“I think when people are asking their opinion when the general public is there, assuming, ‘Hey, if you’re mentally ill, you won’t really know what you want, or you won’t be capable, or you may be temporarily depressed, and that makes you vulnerable.’ But that isn’t what will happen,” he said.

Nicole Scheidl, the executive director of Ottawa-based Physicians for Life, who is strongly opposed to euthanasia, said the idea of extending MAID to cover mental health sufferers should be abandoned permanently.

“Frankly, I think they should drop it,” she said. “I don’t see how there’s any medical evidence to show that they can produce clinical practical guidelines, practice guidelines, that would be useful.”

The Trudeau government has announced the delay will last until at least 2027. This will move the issue until after the next federal election, which must happen no later than October 20, 2025.

NEW YORK — An oversight board is criticizing Facebook owner Meta’s policies regarding manipulated media as “incoherent” and insufficient to address the flood of online disinformation that already has begun to target elections across the globe this year. 

The quasi-independent board on Monday said its review of an altered video of President Joe Biden that spread on Facebook exposed gaps in the policy. The board said Meta should expand the policy to focus not only on videos generated with artificial intelligence, but on media regardless of how it was created. That includes fake audio recordings, which already have convincingly impersonated political candidates in the U.S. and elsewhere. 

It also said Meta should clarify the harm it is trying to prevent and should label images, videos and audio clips as manipulated instead of removing the posts altogether. 

The board’s feedback reflects the intense scrutiny that is facing many tech companies for their handling of election falsehoods in a year when voters in more than 50 countries will go to the polls. As both generative artificial intelligence deepfakes and lower-quality “cheap fakes” on social media threaten to mislead voters, the platforms are trying to catch up and respond to false posts while protecting users’ rights to free speech. 

“As it stands, the policy makes little sense,” oversight board co-chair Michael McConnell said of Meta’s policy in a statement on Monday. He said the company should close gaps in the policy while ensuring political speech is “unwaveringly protected.” 

Meta said it is reviewing the oversight board’s guidance and will respond publicly to the recommendations within 60 days. 

Spokesperson Corey Chambliss said while audio deepfakes aren’t mentioned in the company’s manipulated media policy, they are eligible to be fact-checked and will be labeled or down-ranked if fact-checkers rate them as false or altered. The company also takes action against any type of content if it violates Facebook’s Community Standards, he said. 

Facebook, which turned 20 this week, remains the most popular social media site for Americans to get their news, according to Pew. But other social media sites, among them Meta’s Instagram, WhatsApp and Threads, as well as X, YouTube and TikTok, also are potential hubs where deceptive media can spread and fool voters. 

Meta created its oversight board in 2020 to serve as a referee for content on its platforms. Its current recommendations come after it reviewed an altered clip of Biden and his adult granddaughter that was misleading but didn’t violate the company’s policies because it didn’t misrepresent anything he said. 

The original footage showed Biden placing an “I Voted” sticker high on his granddaughter’s chest, at her instruction, then kissing her on the cheek. The version that appeared on Facebook was altered to remove the important context, making it seem as if he touched her inappropriately. 

The board’s ruling on Monday upheld Meta’s 2023 decision to leave the seven-second clip up on Facebook, since it didn’t violate the company’s existing manipulated media policy. Meta’s current policy says it will remove videos created using artificial intelligence tools that misrepresent someone’s speech. 

“Since the video in this post was not altered using AI and it shows President Biden doing something he did not do (not something he didn’t say), it does not violate the existing policy,” the ruling read. 

The board advised the company to update the policy and label similar videos as manipulated in the future. It argued that to protect users’ rights to freedom of expression, Meta should label content as manipulated rather than removing it from the platform if it doesn’t violate any other policies. 

The board also noted that some forms of manipulated media are made for humor, parody or satire and should be protected. Instead of focusing on how a distorted image, video or audio clip was created, the company’s policy should focus on the harm manipulated posts can cause, such as disrupting the election process, the ruling said. 

Meta said on its website that it welcomes the Oversight Board’s ruling on the Biden post and will update the post after reviewing the board’s recommendations. 

Meta is required to heed the oversight board’s rulings on specific content decisions, though it’s under no obligation to follow the board’s broader recommendations. Still, the board has gotten the company to make some changes over the years, including making messages to users who violate its policies more specific to explain to them what they did wrong. 

Jen Golbeck, a professor in the University of Maryland’s College of Information Studies, said Meta is big enough to be a leader in labeling manipulated content, but follow-through is just as important as changing policy. 

“Will they implement those changes and then enforce them in the face of political pressure from the people who want to do bad things? That’s the real question,” she said. “If they do make those changes and don’t enforce them, it kind of further contributes to this destruction of trust that comes with misinformation.”

SYDNEY — A new study finds that marine heatwaves are changing the base of the marine food chain, disrupting ecosystems and potentially global food supplies.

Researchers in the investigation led by Australia’s national science agency, CSIRO, say their work has global implications.

The study monitored the health of microorganisms that lie at the base of the marine food chain. The survey is part of a long-term project spanning 12 years.

Tiny phytoplankton species developed smaller cells that are not easily consumed by larger animals. Researchers believe this could potentially have “profound changes all the way up the food chain.”

There could also be impacts on the ability of marine ecosystems to absorb – or sequester – carbon and the size of fish stocks.

The study’s lead author Mark Brown tells VOA that the study has far-reaching implications.

“This really is a global issue. Everywhere around the world is experiencing heatwaves. Even the warmest places like the Red Sea are pushing their temperatures higher and higher than the longterm average,” Brown said. “Places like the Arctic and the Antarctic can have marine heatwaves and those might be the places where it is really important to study because any changes to those large polar ecosystems will really have (a) significant impact on the global food stocks.”

Marine heatwaves involve extended periods of abnormally warm ocean water.

Scientists warn they can have significant impacts on marine life, including fish, coral reefs and kelp forests.

The basis of the research by the Commonwealth Scientific and Industrial Research Organization was a marine heatwave in the Tasman Sea off the island state of Tasmania in 2015 to 2016.

The CSIRO team found that the extreme conditions “transformed the microbial community” to resemble those found in far warmer waters 1,000 kilometers to the north.

The CSIRO team says that climate change is intensifying the impact of marine heatwaves, which can also be influenced by naturally occurring weather phenomena, including the El Niño pattern.

Brown says while the organisms they study are small, their importance is huge.

“They are minuscule, and you cannot see them with the naked eye,” he said. “So, all these things are invisible. Just like your gut microbes enable you to have a healthy ecosystem in your body and turn nutrients into energy etcetera, the same processes occur in the ocean, but it is very difficult to study. So, this is why we need to use genomic techniques, DNA sequencing etcetera in order to really analyze what is there.”

The CSIRO findings have been published in the journal Nature’s Communications Biology.

Hong Kong — Scammers tricked a multinational firm out of some $26 million by impersonating senior executives using deepfake technology, Hong Kong police said Sunday, in one of the first cases of its kind in the city.

Law enforcement agencies are scrambling to keep up with generative artificial intelligence, which experts say holds potential for disinformation and misuse — such as deepfake images showing people mouthing things they never said.

A company employee in the Chinese finance hub received “video conference calls from someone posing as senior officers of the company requesting to transfer money to designated bank accounts,” police told AFP.

Police received a report of the incident on January 29, at which point some HK$200 million ($26 million) had already been lost via 15 transfers.

“Investigations are still ongoing and no arrest has been made so far,” police said, without disclosing the company’s name.

The victim was working in the finance department, and the scammers pretended to be the firm’s U.K.-based chief financial officer, according to Hong Kong media reports.

Acting Senior Superintendent Baron Chan said the video conference call involved multiple participants, but all except the victim were impersonated.

“Scammers found publicly available video and audio of the impersonation targets via YouTube, then used deepfake technology to emulate their voices… to lure the victim to follow their instructions,” Chan told reporters.

The deepfake videos were pre-recorded and did not involve dialogue or interaction with the victim, he added.

Mosocw — Russian cosmonaut Oleg Kononenko on Sunday set a world record for total time spent in space, surpassing his compatriot Gennady Padalka who logged more than 878 days in orbit, Russia’s space corporation said.

At 0830 GMT Kononenko broke the record, Roscosmos said. Kononenko is expected to reach a total of 1,000 days in space on June 5 and by late September he will have clocked 1,110 days.

“I fly into space to do my favorite thing, not to set records,” Kononenko told TASS in an interview from the International Space Station (ISS) where he is orbiting about 263 miles (423 km) from Earth.

“I am proud of all my achievements, but I am more proud that the record for the total duration of human stay in space is still held by a Russian cosmonaut.”

The 59-year-old took the top spot from Padalka, who accumulated a total of 878 days, 11 hours, 29 minutes and 48 seconds, Roscosmos said.

The Soviet Union spooked the West in the early years of the space race by being first to launch a satellite to orbit the Earth — Sputnik 1, in 1957 — and then Soviet cosmonaut Yuri Gagarin became the first man to travel into space in 1961.

But after the 1991 collapse of the Soviet Union, Russia’s space program grappled with massive funding shortages and corruption.

Officials under President Vladimir Putin have repeatedly vowed to turn around the decline of Russia’s space programs, though serious problems remain, according to officials and space analysts.

Life in space

Kononenko said that he worked out regularly to counter the physical effects of  “insidious” weightlessness, but that it was on returning to Earth that the realization came of how much life he had missed out on.

“I do not feel deprived or isolated,” he said.

“It is only upon returning home that the realization comes that for hundreds of days in my absence the children have been growing up without a papa. No one will return this time to me.”

He said cosmonauts could now use video calls and messaging to keep in touch with relatives but getting ready for each new space flight became more difficult due to technological advances.

“The profession of a cosmonaut is becoming more complicated. The systems and experiments are becoming more complicated. I repeat, the preparation has not become easier,” he said.

Kononenko dreamed of going to space as a child and enrolled in an engineering institute, before undergoing cosmonaut training. His first space flight was in 2008.

His current trip to the ISS launched last year on a Soyuz MS-24.

The ISS is one of the few international projects on which the United States and Russia still cooperate closely. In December, Roscosmos said that a cross-flight program with NASA to the ISS had been extended until 2025.

Relations in other areas between the two countries have broken down since Russia’s invasion of Ukraine nearly two years ago, to which Washington responded by sending arms to Kyiv and imposing successive rounds of sanctions on Moscow.

WASHINGTON — One of the great interspecies love stories of our time has come to an end.

Walnut, a white-naped crane and internet celebrity, has died at age 42. She is survived by eight chicks, the loving staff at the Smithsonian’s National Zoo and Conservation Biology Institute and by Chris Crowe, a human zookeeper whom Walnut regarded as her mate for nearly 20 years.

“Walnut was a unique individual with a vivacious personality,” Crowe said, in a statement released by the National Zoo. “I’ll always be grateful for her bond with me.”

The tale of Walnut (and Chris) has inspired internet fame and the occasional love song. It dates back to the bird’s 2004 arrival at the institute’s campus in Front Royal, Virginia.

The chick of two wild cranes who had been brought to the U.S. illegally and were later rescued by the International Crane Foundation, Walnut was hand-raised by people and bonded with her human caretakers. That preference continued when she came to the institute; she showed no interest in breeding and even attacked male crane suitors.

But white-naped cranes are considered vulnerable by the International Union for Conservation of Nature. Today, fewer than 5,300 remain in their native habitats in Mongolia, Siberia, Korea, Japan and China due to habitat loss, pollution, nest predation and poaching. And as the offspring of two wild-caught cranes, Walnut’s genes were not represented in U.S. zoos. So convincing Walnut to breed was regarded as a priority.

In stepped Crowe, who, according to a zoo statement, won her over by “observing and mimicking” the institute’s male white-naped cranes’ actions during breeding season.

Videos show Crowe offering Walnut food as well as grass and leaves for nest-building materials. When he flaps his arms in front of her, the tall majestic bird flaps excitedly in response and dances in a half-circle with her head bobbing. Once Crowe had gained her trust, he was able to artificially inseminate her using sperm from a male crane.

The unique arrangement proved wildly successful, and Walnut had eight chicks. The fertilized eggs were given to other white-napped crane pairs who tended to them as their own. Of the eight white-napped cranes currently living at the institute, one is Walnut’s chick and another is her grand-chick.

The relationship also seems to have been beneficial for Walnut’s health; at 42, she nearly tripled the median life expectancy of 15 years for white-naped cranes in human care.

Walnut was born in Wisconsin in the summer of 1981. She was named after a local Wisconsin restaurant’s popular walnut pie dessert.

Starting on the morning of Jan. 2, keepers noticed that Walnut wasn’t eating or drinking. Not even offers of her favorite treats — frozen-thawed mice, peanuts and mealworms — couldn’t spark her appetite. Veterinarians administered fluids and antibiotics and drew blood for analysis. But her health continued to decline and Walnut was eventually hospitalized. She died peacefully, surrounded by an animal care team; an autopsy revealed the cause of death to be renal failure.

“She was always confident in expressing herself, an eager and excellent dancer, and stoic in the face of life’s challenges,” Crowe said. “Walnut’s extraordinary story has helped bring attention to her vulnerable species’ plight. I hope that everyone who was touched by her story understands that her species’ survival depends on our ability and desire to protect wetland habitats.”

new york — This New York love story begins with a criminal act of sabotage. 

Under cover of darkness a year ago Friday, someone breached a waist-high fence and slipped into the Central Park Zoo. Once inside, they cut a hole through a steel mesh cage, freeing a majestic Eurasian eagle-owl named Flaco who had arrived at the zoo as a fledgling 13 years earlier. 

Immediately, Flaco fled the park, blinking his big orange eyes at pedestrians and police on Fifth Avenue before flying off into the night. 

In the year since his dramatic escape, Flaco has become one of the city’s most beloved characters. By day he lounges in Manhattan’s courtyards and parks or perches on fire escapes. He spends his nights hooting atop water towers and preying on the city’s abundant rats. 

To the surprise of many experts, Flaco is thriving in the urban wilds. An apex predator with a nearly 6-foot (2-meter) wingspan, he has called on abilities some feared he hadn’t developed during a lifetime in captivity, gamely exploring new neighborhoods and turning up unexpectedly at the windows of New Yorkers. 

“He was the underdog from the start. People did not expect him to survive,” said Jacqueline Emery, one of several birders who document the owl’s daily movements and share them online with his legions of admirers. “New Yorkers especially connect to him because of his resilience.” 

But as Flaco enters his second year in the spotlight, it can be easy to forget that his freedom is the result of a crime, one that has improbably remained unsolved. 

‘This was a crime’

The break-in happened steps from the shared headquarters of the New York City Parks Department and the Central Park Zoo, in the vicinity of at least one surveillance camera. 

But if they have collected any evidence on a potential suspect, police and zoo authorities have declined to share it. Since the zoo suspended efforts to re-capture Flaco in February 2023, there has been no public information about the crime. 

Privately, the zoo has sought to soften descriptions of Flaco’s former living conditions, in a minivan-sized structure decorated with a painted mountain vista, barely twice the width of Flaco’s extended wings. 

In internal emails obtained through a Freedom of Information request, zoo officials urged the Parks Department not to publicly describe Flaco as “raised in captivity.” Likewise, the term “escape” should be avoided. 

“That puts the blame on the animal rather than the perpetrator,” the zoo’s then-communications director, Max Pulsinelli, wrote in one email. “This was a crime.” 

In the absence of official information, theories of the crime abound — a youthful prank, perhaps, or an attempted owl heist gone awry? For many invested in Flaco’s fate, the most plausible explanation is that he was freed for ideological reasons. 

Proponents of the animal liberation theory point to the seemingly targeted nature of the crime, as well as the limitations of the owl’s modest enclosure. 

“I wouldn’t be surprised if it was someone who loved Flaco and wanted him free,” said Nicole Barrantes, a wildlife campaign manager with World Animal Protection, who started a petition against Flaco being returned to the zoo. “His habitat was ridiculous. It was the saddest thing ever.” 

Break-ins and vandalism have long been tactics some activists have used to free animals. Such actions are often made public by the North American Animal Liberation Press Office, an anonymous online database. 

The group’s spokesperson, Jerry Vlasak, said no one had come forward to claim responsibility for Flaco’s escape. “We never received a communique,” he said. “But we’re certainly glad it happened.” 

A spokesperson for the Wildlife Conservation Society, which has operated the zoo since 1988, did not respond to the claims that Flaco’s zoo habitat was inadequate. 

“This was a criminal act that jeopardized the safety of the bird,” the zoo said in a statement, adding that they are continuing to monitor reports of Flaco’s activity and wellbeing and are “prepared to resume recovery efforts if he shows any sign of difficulty or distress.” 

Threats in the city

Even with his proficient hunting skills, Flaco faces many threats in the city, including a grave risk of consuming rodenticide through a poisoned rat. In 2021, another beloved Central Park owl, Barry, was fatally struck by a truck after ingesting a lethal dose of rat poison that may have impaired her flying. 

“All the hazards are still there,” cautioned Suzanne Shoemaker, the director of the Owl Moon Raptor Center in Maryland. “He’s shown some good instincts to be able to make it this far. He’s also lucky.” 

Flaco spent his initial months of freedom mostly in Central Park, which is loaded with wildlife, but has lately preferred more urban sections of Manhattan. There has been some speculation that he has been looking for a mate, though he most certainly won’t find one. Eurasian eagle owls aren’t native to North America. 

Stories of zoo animals breaking loose in the middle of the country’s densest city have long captured the public imagination, while often ushering in calls for reforms. 

Following a series of bird thefts and “senseless” animal beatings in the 1970s, administrators ordered immediate security upgrades and the redesign of some pens at the zoo, which the city’s parks commissioner at the time described as “Rikers Island for animals” because of poor living conditions. 

A few years later, when a group of vandals made off with a boa constrictor and a parrot named “Peanuts,” officials accused the perpetrators of stealing the animals for “voodoo rites.” 

Since those days the zoo has been substantially redesigned. 

Wildlife groups have long warned that owls can be used as sacrifices in certain religious ceremonies — particularly birds like Flaco, who boasts prominent ear tufts. The Eurasian eagle-owl is also commonly used in falconry, selling for as much as $3,000. 

But while some have suggested Flaco was targeted for either financial or spiritual purposes, such speculation would seem undermined by the fact that he emerged from his damaged cage and into the bustling cityscape unscathed. 

On a recent night on Manhattan’s Upper West Side, one of the Flaco’s most dedicated observers, David Barrett, struck an ambivalent tone when asked how New Yorkers should think about the crime that made him an avian celebrity. 

“To me, the folk hero is Flaco,” said Barrett, who runs the X account Manhattan Bird Alert, documenting the bird’s whereabouts in real time. “It’s an amazing thing: He lives his whole life in captivity and in a matter of days he taught himself to fly and to hunt rats.” 

Tuning his ears skyward, Barrett listened for the signature hoot that had echoed across Broadway on so many recent nights. 

“It’s not our business to try to solve crimes,” he said. “We’re just glad he’s here.”

BEIJING — A small but powerful Chinese rocket capable of carrying payloads at competitive costs delivered nine satellites into orbit Saturday, Chinese state media reported, in what is gearing up to be another busy year for Chinese commercial launches. 

The Jielong-3, or Smart Dragon-3, blasted off from a floating barge off the coast of Yangjiang in southern Guangdong province, the second launch of the rocket in just two months. 

Developed by China Rocket Company, a commercial offshoot of a state-owned launch vehicle manufacturer, Jielong-3 made its first flight in December 2022. 

President Xi Jinping has called for the expansion of strategic industries including the commercial space sector, deemed key to building constellations of satellites for communications, remote sensing and navigation. 

Also Saturday, Chinese automaker Geely Holding Group launched 11 satellites to boost its capacity to provide more accurate navigation for autonomous vehicles. 

Last year saw 17 Chinese commercial launches with one failure, among a record 67 orbital launches by China. That was up from 10 Chinese commercial launches in 2022, including two failures. 

In 2023, China conducted more launches than any other country except for the United States, which made 116 launch attempts, including just under 100 by Elon Musk’s SpaceX. 

Critical to the construction of commercial satellite networks is China’s ability to open more launch windows, expand rocket types to accommodate different payload sizes, lower launch costs and increase the number of launch sites.

WASHINGTON — Women are far more likely than men to get autoimmune diseases, when an out-of-whack immune system attacks their own bodies — and new research may finally explain why.

It’s all about how the body handles females’ extra X chromosome, Stanford University researchers reported Thursday — a finding that could lead to better ways to detect a long list of diseases that are hard to diagnose and treat.

“This transforms the way we think about this whole process of autoimmunity, especially the male-female bias,” said University of Pennsylvania immunologist E. John Wherry, who wasn’t involved in the study.

More than 24 million Americans, by some estimates up to 50 million, have an autoimmune disorder — diseases such as lupus, rheumatoid arthritis, multiple sclerosis and dozens more. About 4 of every 5 patients are women, a mystery that has baffled scientists for decades.

One theory is that the X chromosome might be a culprit. After all, females have two X chromosomes while males have one X and one Y.

The new research, published in the journal Cell, shows that extra X is involved — but in an unexpected way.

Our DNA is carried inside each cell in 23 pairs of chromosomes, including that final pair that determines biological sex. The X chromosome is packed with hundreds of genes, far more than males’ much smaller Y chromosome. Every female cell must switch off one of its X chromosome copies, to avoid getting a toxic double dose of all those genes.

Performing that so-called X-chromosome inactivation is a special type of RNA called Xist, pronounced like “exist.” This long stretch of RNA parks itself in spots along a cell’s extra X chromosome, attracts proteins that bind to it in weird clumps, and silences the chromosome.

Stanford dermatologist Dr. Howard Chang was exploring how Xist does its job when his lab identified nearly 100 of those stuck-on proteins. Chang recognized many as related to skin-related autoimmune disorders — patients can have “autoantibodies” that mistakenly attack those normal proteins.

“That got us thinking: These are the known ones. What about the other proteins in Xist?” Chang said. Maybe this molecule, found only in women, “could somehow organize proteins in such a way as to activate the immune system.”

If true, Xist by itself couldn’t cause autoimmune disease or all women would be affected. Scientists have long thought it takes a combination of genetic susceptibility and an environmental trigger, such as an infection or injury, for the immune system to run amok. For example, the Epstein-Barr virus is linked to multiple sclerosis.

Chang’s team decided to engineer male lab mice to artificially make Xist — without silencing their only X chromosome — and see what happened.

Researchers also specially bred mice susceptible to a lupus-like condition that can be triggered by a chemical irritant.

The mice that produced Xist formed its hallmark protein clumps and, when triggered, developed lupus-like autoimmunity at levels similar to females, the team concluded.

“We think that’s really important, for Xist RNA to leak out of the cell to where the immune system gets to see it. You still needed this environmental trigger to cause the whole thing to kick off,” explained Chang, who is paid by the Howard Hughes Medical Institute, which also supports The Associated Press’ Health and Science Department.

Beyond mice, researchers also examined blood samples from 100 patients — and uncovered autoantibodies targeting Xist-associated proteins that scientists hadn’t previously linked to autoimmune disorders. A potential reason, Chang suggests: standard tests for autoimmunity were made using male cells.

Much more research is necessary but the findings “might give us a shorter path to diagnosing patients that look clinically and immunologically quite different,” said Penn’s Wherry.

“You may have autoantibodies to Protein A and another patient may have autoantibodies to Proteins C and D,” but knowing they’re all part of the larger Xist complex allows doctors to better hunt disease patterns, he added. “Now we have at least one big part of the puzzle of biological context.”

Stanford’s Chang wonders if it may even be possible to one day interrupt the process.

“How does that go from RNA to abnormal cells, this will be a next step of the investigation.”

NEW YORK — A graphic video from a Pennsylvania man accused of beheading his father that circulated for hours on YouTube has put a spotlight yet again on gaps in social media companies’ ability to prevent horrific postings from spreading across the web.

Police said Wednesday that they charged Justin Mohn, 32, with first-degree murder and abusing a corpse after he beheaded his father, Michael, in their Bucks County home and publicized it in a 14-minute YouTube video that anyone, anywhere could see.

News of the incident — which drew comparisons to the beheading videos posted online by the Islamic State militants at the height of their prominence nearly a decade ago — came as the CEOs of Meta, TikTok and other social media companies were testifying in front of federal lawmakers frustrated by what they see as a lack of progress on child safety online. YouTube, which is owned by Google, did not attend the hearing despite its status as one of the most popular platforms among teens.

The disturbing video from Pennsylvania follows other horrific clips that have been broadcast on social media in recent years, including domestic mass shootings livestreamed from Louisville, Kentucky; Memphis, Tennessee; and Buffalo, New York — as well as carnages filmed abroad in Christchurch, New Zealand, and the German city of Halle.

Middletown Township Police Capt. Pete Feeney said the video in Pennsylvania was posted at about 10 p.m. Tuesday and online for about five hours, a time lag that raises questions about whether social media platforms are delivering on moderation practices that might be needed more than ever amid wars in Gaza and Ukraine, and an extremely contentious presidential election in the U.S.

“It’s another example of the blatant failure of these companies to protect us,” said Alix Fraser, director of the Council for Responsible Social Media at the nonprofit advocacy organization Issue One. “We can’t trust them to grade their own homework.”

A spokesperson for YouTube said the company removed the video, deleted Mohn’s channel and was tracking and removing any re-uploads that might pop up. The video-sharing site says it uses a combination of artificial intelligence and human moderators to monitor its platform but did not respond to questions about how the video was caught or why it wasn’t done sooner.

Major social media companies moderate content with the help of powerful automated systems, which can often catch prohibited content before a human can. But that technology can sometimes fall short when a video is violent and graphic in a way that is new or unusual, as it was in this case, said Brian Fishman, co-founder of the trust and safety technology startup Cinder.

That’s when human moderators are “really, really critical,” he said. “AI is improving, but it’s not there yet.”

The Global Internet Forum to Counter Terrorism, a group set up by tech companies to prevent these types of videos from spreading online, was in communication with its all of its members about the incident on Tuesday evening, said Adelina Petit-Vouriot, a spokesperson for the organization.

Roughly 40 minutes after midnight Eastern time on Wednesday, GIFCT issued a “Content Incident Protocol,” which it activates to formally alert its members – and other stakeholders – about a violent event that’s been livestreamed or recorded. GIFCT allows the platform with the original footage to submit a “hash” — a digital fingerprint corresponding to a video — and notifies nearly two dozen other member companies so they can restrict it from their platforms.

But by Wednesday morning, the video had already spread to X, where a graphic clip of Mohn holding his father’s head remained on the platform for at least seven hours and received 20,000 views. The company, formerly known as Twitter, did not respond to a request for comment.

Experts in radicalization say that social media and the internet have lowered the barrier to entry for people to explore extremist groups and ideologies, allowing any person who may be predisposed to violence to find a community that reinforces those ideas.

In the video posted after the killing, Mohn described his father as a 20-year federal employee, espoused a variety of conspiracy theories and ranted against the government.

Most social platforms have policies to remove violent and extremist content. But they can’t catch everything, and the emergence of many newer, less closely moderated sites has allowed more hateful ideas to fester unchecked, said Michael Jensen, senior researcher at the University of Maryland-based Consortium for the Study of Terrorism and Responses to Terrorism, or START.

Despite the obstacles, social media companies need to be more vigilant about regulating violent content, said Jacob Ware, a research fellow at the Council on Foreign Relations.

“The reality is that social media has become a front line in extremism and terrorism,” Ware said. “That’s going to require more serious and committed efforts to push back.”

Nora Benavidez, senior counsel at the media advocacy group Free Press, said among the tech reforms she would like to see are more transparency about what kinds of employees are being impacted by layoffs, and more investment in trust and safety workers.

Google, which owns YouTube, this month laid off hundreds of employees working on its hardware, voice assistance and engineering teams. Last year, the company said it cut 12,000 workers “across Alphabet, product areas, functions, levels and regions,” without offering additional detail.
