"Billionaire Bill Ackman's life was upended this February when his 26-year-old daughter collapsed in her Brooklyn apartment, suffering a brain hemorrhage that would render her unable to move, speak or see," writes the Washingon Post. But then... The hedge fund manager did what any good father would do — at least, any father with vast financial resources and what friends describe as a "Mr. Fix-It" tendency. He sprung into action, getting her topline care at New York City's Mt. Sinai Hospital and consulting a network of well-connected friends all over the world. He helped her access a novel cell therapy that has been gaining traction among longevity enthusiasts, who are seeking ways to prolong human life. And then — motivated by a newfound desire to accelerate scientific research — he vowed to spend more than $400 million to launch an institute dedicated to longevity and brain health... He posted this week that the U.S. Food and Drug Administration, in May, gave his daughter Lucy's medical team a first-time emergency authorization to transplant mitochondria — the energy-producing part of human cells — from her leg muscle to her eyes, in the hopes that the tiny cell powerhouses would facilitate healing in her optic nerves and perhaps even restore her vision. Ackman's story highlights the increasingly prominent role of the ultra-wealthy in making expensive medical bets on longevity treatments and other novel therapies, altering the direction of research as federal funding for science declines in the second Trump administration. But his saga is a deeply personal one, spurred by his daughter's medical crisis. The focus on longevity by Ackman, who made billions on Wall Street as a hedge fund manager, is aligned with similarly ambitious efforts from some of Silicon Valley's biggest names. OpenAI CEO Sam Altman has backed Retro Biosciences, a start-up whose goal is to add 10 healthy years to the human lifespan through cellular reprogramming. Amazon founder Jeff Bezos is reportedly a funder of Altos Labs, which focuses on cellular rejuvenation and resilience... Billionaire investor Peter Thiel, Google co-founder Sergey Brin and Oracle co-founder Larry Ellison are also deeply invested in life-extension methods and attempts to rewrite the biology of aging... The therapy given to Ackman's daughter Lucy, known as mitochondrial transplantation, is of great interest not only to people who have suffered injuries, but to longevity-focused scientists who believe that mitochondria may hold promise for reversing some of the effects of aging... In recent years, scientists have discovered that mitochondria have many other functions beyond converting food into energy. They serve as clearinghouses for damaged cells, opening up the possibility that they can help with cell regeneration and healing, said Daria Mochly-Rosen, professor of chemical and systems biology at the Stanford University School of Medicine and co-author of " The Life Machines: How Taking Care of Your Mitochondria Can Transform Your Health." "I am one of those who believes that focusing on mitochondrial health is a way to address many human diseases, including aging itself," she said. "It's exciting."

A new article about AI in The Economist argues that "Initial effects of the technology on employment look positive." Perhaps AI will eventually make many humans unemployable — but there is no sign of it yet. On September 4th the Bureau of Labour Statistics reported that the American economy added 162,000 jobs in August, far above expectations. The unemployment rate is just 4.1%, lower than in almost 90% of months over the past half-century. Young workers, often cast as AI's first victims, are holding up remarkably well: the gap between unemployment among 20-24-year-olds and the overall rate is close to a multi-decade low. Some companies and workers are being severely disrupted by AI. Hiring in professional and business services is running about 10% below the average in 2015-19. Tech giants like Microsoft and Meta are trimming headcounts as they reorganise their businesses around the technology. Smaller firms such as Block, the owner of Square and Cash App, and Intuit, the maker of TurboTax and QuickBooks, are replacing people with bots. American companies have announced some 16,000 AI-related job cuts a month on average so far this year, according to Challenger, Gray & Christmas, an employment consultancy. But AI-related lay-offs gets lost in the churning jobs market where employers shed roughly 1.7m workers in a typical month. And the evidence so far is that AI is already creating a lot of jobs to replace those it has destroyed. The vast sums pouring into data centres and power generation have set off a race for construction and infrastructure workers. AI startups are hiring like there is no tomorrow. Incumbents racing to keep up are creating new AI roles. And by making some workers more productive, AI may be increasing demand for their services. Add it all up, and The Economist estimates that AI has so far created around 1m new jobs in America. That easily exceeds the roughly 200,000 lay-offs attributed to AI since mid-2023, and appears more than enough to offset weaker hiring in many back-office roles. Their article acknowledges that since January 2023 employment has fallen roughly 10% for customer-service workers and 15% for administrative assistants. But when The Economist looked at professions "closest to the AI boom" — engineers, software developers, mathematicians and data scientists — they found that since 2022 they've added roughly 730,000 jobs above trend. They see AI as creating new white-collar jobs for everyone from model and deployment engineers to new data annotators. The chief economist at the Burning Glass Institute agrees, estimating that roughly 1% of professional jobs are now "AI jobs" — about 1 million positions in the U.S. — while in computer occupations and life sciences it's between 4% and 5%. (Data-center construction spending also increased 60% in one year, according to Census Bureau data, creating jobs for electricians, HVAC specialists, grid engineers, and machine technicians.) And "Indeed finds that installation and maintenance jobs at data centres advertise wages about 40% higher than comparable work elsewhere."

Reuters reports: Liquid Network, a Bitcoin-based payments and settlement network, said on Sunday that about $320 million was withdrawn from its federation wallet in a hack. "Purported white-hat hackers" withdrew around 4,000 of the 4,200 bitcoin held in its Liquid Federation wallet, Liquid Network said in a post on X. "Liquid wallets will be impacted," their post concluded, adding "and we're sorry for any inconvenience."

A new streaming TV channel shows films made with genAI, reports Engadget. "Fairground AI Creator TV" is free — and supported with ads — describing its material as "AI Cinema": "AI-generated" can make it sound as though someone typed a sentence into a machine and came back five minutes later to find a finished movie. Fairground's catalog shows why that description can be too simple. Take Lost Garden: The Awakening of the Lantern Knight. According to its Fairground page, creator Frank Houbre wrote the world, characters, mythology, emotional arc and screenplay himself. AI tools were used mainly for animation and visual production, with other tools helping create voices and music before the episode was assembled in conventional video-editing software. There's still one question, the article notes: "whether viewers actually want an AI-focused TV channel." More than 100 AI creators have contributed to the 24-hour slate of programming, although Variety points out several of them were discovered on social media. The channel was recently profiled in an article by the Guardian. Its headline? "'Nightmare fodder': Roku's AI slop channel is even worse than expected." (And its subheading calls it "a 24/7 channel devoted to low-quality AI content for viewers sick of watching real people move...") What about people who hate plot and vision and the sight of people speaking convincing dialogue that synchronises perfectly with the movement of their lips? What about the people who just want to watch an unyielding torrent of eerily weightless nightmare fodder? Well, good news. Roku has finally caught up... Early reactions were, to put it mildly, not great. The Verge compared it to eating from a trough, while Futurism called it "bottom-of-the-barrel slop"... On the plus side, the channel is evidence that artificial intelligence has come on in leaps and bounds over the last couple of years... However, it is still awful. Categorically, catastrophically awful. The channel doesn't so much offer shows as a drifting dreamscape of bad ideas rendered as horribly as possible with no thought paid to scheduling. At one point on Wednesday, a shrill high-frequency anime gave way to a long and staid German-language short about Nazi bureaucracy. After that came a sort of Gladiator ripoff that had all the dynamism of an exhibit you'd see at the fourth-best museum on a poorly planned family holiday.

Slashdot reader DeanonymizedCoward writes: Reuters reports that the US Military is disabling ad tracking on devices, to prevent adversaries from buying publicly-available tracking data to assist in targeting troops. Military officials say that they have disabled trackers on a variety of computers and mobile devices, according to letters released on Friday by Sen. Ron Wyden, and following reports that commercially-available tracking data has been used to target troops in the Middle East.... Wyden said in a statement that it was clear that the military's efforts "have not been effective at neutralizing this threat." U.S. Representative Pat Harrigan, a North Carolina Republican, said that U.S. enemies "should not be able to pull out a credit card and buy information that helps them track American troops." Rep. Harrigan remains silent as to the larger question of whether the general public should be able to pull out a credit card and buy information that helps them track anyone they please. "The Pentagon said in an email it would respond to the lawmakers directly," Reuters reports: The Army said in a statement that advertising IDs had been blocked on Windows computers "since before 2021" but that Android and Apple mobile devices had only had it disabled by default "since at least February 2026...." The effort to reduce the location data generated by smartphones comes as military officials weigh increasingly strict restrictions on phone use overall. In July, Reuters reported that some deployed personnel in the Middle East could be ordered to surrender their phones amid concerns that mobile videos they were posting to the internet were helping Iran target American bases in the region.

A new study published Friday in AGU Advances "depicts the most advanced picture yet of how a rare but massive solar storm could affect some US industries and electric systems more than others," reports CNN. "During a 250-year solar storm, the East Coast would have widespread potential for grid failure." Researchers modeled what a Carrington Event — a 1-in-150-year geomagnetic storm or even rarer — could mean for the modern day. They estimate the US economy would lose about $1.5 billion to $2 billion per day from direct and indirect costs, as millions of people face power outages. The findings show the most vulnerable areas are the Northeast and the Northern Plains, especially locations at higher latitudes. No one knows when the next big storm will hit. While the most severe geomagnetic storms are labeled as once-in-a-century or rarer, these events don't follow a fixed schedule. "That timing only averages out on very long timescales," said Anna Kelbert, a geophysicist at the Harvard-Smithsonian Center for Astrophysics, who was not involved in the study but previously studied solar storm effects on power grids. "The event can occur at any time, as soon as a week from now, or centuries later...." [Shawn Dahl, service coordinator at the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration in Boulder, Colorado], said the sun is now coming down from a period of heightened activity, which is also when some of the biggest storms to hit Earth have occurred in the past. "We still need a lot of work to be ready...." "We haven't really seen events like this size in the modern era, where we've had all of this high technology and we've had the power grid of this size," said Ed Oughton, researcher at George Mason University and lead author of the new study... Because the US grid's actual structure is proprietary for security reasons, the team used engineering models to create various network and transformer setups including the 10,464 substations and 16,256 transmission lines found across the country... The grid structure also contributes to higher risk in some areas. For instance, the eastern US is linked together in a single grid interconnection. A voltage issue in Maine, if not isolated early, could cascade through the grid to Washington, DC. The West works similarly, whereas the Texas interconnection operates mostly within the state... Power is restored over time depending on any alternative electrical paths that could bypass the substation or availabilities of spare transformers, for instance. "This nationwide analysis shows that we are currently ill-prepared to face a major magnetic storm, and that the societal impacts would be catastrophic," Kelbert said. "The study estimates power disruptions for 5.1 million people and 135,000 businesses," according to the article, and "The outages could last from hours to days to weeks depending on the damage and resources available to get back online, said Oughton."
