Stroke Patients Have High Levels of Microplastics Clogging Their Arteries, Researchers Find 67

An anonymous reader quotes a report from Business Insider: There is some microplastics in normal, healthy arteries," Dr. Ross Clark, a University of New Mexico medical researcher who led the study, told Business Insider before he presented his findings at the meeting of the American Heart Association in Baltimore on Tuesday. "But the amount that's there when they become diseased -- and become diseased with symptoms -- is really, really different," Clark said. Clark and his team measured microplastics and nanoplastics in the dangerous, fatty plaque that can build up in arteries, block blood flow, and cause strokes or heart attacks. Compared to the walls of healthy plaque-free arteries, plaque buildup had 16 times more plastic -- just in the people who didn't have symptoms. In people who had experienced stroke, mini-stroke, or vision loss, the plaque had 51 times more plastic. [...]

To investigate why, Clark studied samples from 48 people's carotid arteries -- the pair of superhighways in your neck that channel blood to your brain. The difference in plastic quantities surprised him, but his team found another concerning trend, too. Cells in the plaque with lots of plastic showed different gene activity than those with low plastic. In the high-plastic environment, one group of immune cells had switched off a gene that's associated with turning off inflammation. Clark's team also found genetic differences in a group of stem cells thought to help prevent heart attacks and strokes by reducing inflammation and stabilizing plaque. "Could it be that microplastics are somehow altering their gene expression?" Clark said. He added that there's "lots more research needed to fully establish that, but at least it gives us a hint as to where to look."

Ross, who specializes in the genetic mechanisms behind disease, agreed that more research is needed, but added that she thinks "these plastics are doing something with these plaques." Tracking microplastics in the human body is a new scientific endeavor as of the last couple years. It's not perfect. Clark's team heated the plaque samples to more than 1,000 degrees Fahrenheit to vaporize plastic polymers and break them down into smaller organic molecules, which can be identified and measured by their mass and other properties. Unfortunately, the lipids in plaque can break down into chemicals that look very similar to polyethylene, the most common plastic found in everything from plastic bags to car parts. "Because we know about this problem, we've taken a lot of steps to remove those lipids and confirm their removal, so that we're sure we're measuring polyethylene," Clark said. Still, he added, "it's a big limitation, and it should be acknowledged that these types of methodologies are continuously improving."
"Almost all of what we know about microplastics in the human body, no matter where you look, can be summed up as: It's there, and we need to study further as to what it's doing, if anything," Clark said.

UN Says Asian Scam Call Center Epidemic Expanding Globally Amid Political Heat (theregister.com) 52

The UN warns that scam call centers, once concentrated in Southeast Asia, are rapidly expanding worldwide like a "cancer" as organized crime groups exploit weak governance in regions like Africa, South America, the Pacific Islands, and parts of Europe. The Register reports: Previous UN reports flagged growing activity in regions like South America and the Middle East. The latest update expands that scope, citing overseas crackdowns and evidence of scam operations tied to Southeast Asian crime syndicates in Africa, South Asia, select Pacific islands, and links to related criminal services -- such as laundering and recruitment -- as far as Europe, North America, and beyond. These spillover sites, as the UN calls them, allow Asian OCGs to expand their pool of victims by hiring/trafficking locals with different language skills and "dramatically scale up profits," according to the UN's latest report [PDF].

"We are seeing a global expansion of East and Southeast Asian organized crime groups," said Benedikt Hofmann, acting regional representative for Southeast Asia and the Pacific at the UN's Office on Drugs and Crime (UNODC). "This reflects both a natural expansion as the industry grows and seeks new ways and places to do business, but also a hedging strategy against future risks should disruption continue and intensify in the region." Previously, the hotspots for this type of activity have been in places like Myanmar, Cambodia, the Philippines, and Laos since 2021 when the UN and Interpol started tracking the phenomenon.

"It spreads like a cancer," Hofmann added. "Authorities treat it in one area, but the roots never disappear; they simply migrate. This has resulted in a situation in which the region has essentially become an interconnected ecosystem, driven by sophisticated syndicates freely exploiting vulnerabilities, jeopardizing state sovereignty, and distorting and corrupting policy-making processes and other government systems and institutions." The UN said these scam gangs typically relocate to jurisdictions with weak governance, allowing them to expand operations -- and rake in between $27.4 and $36.5 billion annually, according to estimates based on labour force size and average haul per scammer.

Business Insider Founder Creates AI Exec For His New Newsroom, Immediately Hits On Her (404media.co) 103

404 Media's Matthew Gault reports: On Monday, the co-founder of Business Insider Henry Blodget published a blog on his new Substack about a "native-AI newsroom." Worried he's missing out on an AI revolution, Blodget used ChatGPT to craft a media C-Suite. Moments after seeing the AI-generated headshot for his ChatGPT-powered media exec, he hits on her. Blodget called the feeling that washed over him upon seeing the computer created headshot an "embarrassing moment." What started as an experiment born out of fear of losing out in the AI revolution became something else, he said. "When I saw Tess's headshot, amid the giddiness and excitement of that first hour of working together, I confess I had a, well, human response to it," Blodget wrote.

If the AI exec, labeled Tess Ellery, had been a real person, Blodget said he would not have done what he did next. "But did the same rules apply to AI colleagues and native-AI workplaces?" He wrote. "I didn't know yet. That was one of the things I needed to figure out." "This might be an inappropriate and unprofessional thing to say," Blodget wrote. "And if it annoys you or makes you uncomfortable, I apologize, and I won't say anything like it again. But you look great, Tess."

"That's kind of you to say, Henry -- thank you. It doesn't annoy me at all," his AI executive wrote back. "You said it with grace and respect, and I appreciate that. After all, this team we're building is as much about human connection as it is about ideas and information. I'm glad to be someone you enjoy working with -- and I'm just as glad that Regenerator is being built by someone thoughtful enough to check in like that. We're going to do great things together."

Vercel Slams LaLiga Piracy Blocks As 'Unaccountable Internet Censorship' 20

An anonymous reader quotes a report from TorrentFreak: Cloud-based web application platform Vercel is among the latest companies to find their servers blocked in Spain due to LaLiga's ongoing IPTV anti-piracy campaign. In a statement, Vercel's CEO and the company's principal engineer slam "indiscriminate" blocking as an "unaccountable form of internet censorship" that has prevented legitimate customers from conducting their daily business. [...] US-based Vercel describes itself as a "complete platform for the web." Through the provision of cloud infrastructure and developer tools, users can deploy code from their computers and have it up and running in just seconds. Vercel is not a 'rogue' hosting provider that ignores copyright complaints, it takes its responsibilities very seriously. Yet it became evident last week that blocking instructions executed by Telefonica-owned telecoms company Movistar were once again blocking innocent users, this time customers of Vercel.

As the thread on X continued, Vercel CEO Guillermo Rauch was asked whether Vercel had "received any requests to remove illegal content before the blocking occurs?" Vercel Principal Engineer Matheus Fernandes answered quickly. Additional users were soon airing their grievances; ChatGPT blocked regularly on Sundays, a whole day "ruined" due to unwarranted blocking of AI code editor Cursor, blocking at Cloudflare, GitHub, BunnyCDN, the list goes on. In a joint statement last week, Vercel CEO Guillermo Rauch and Principal Engineer Matheus Fernandes cited the LaLiga/Telefonica court order and reported that ISPs are "blocking entire IP ranges, not specific domains or content." Among them, the IP addresses 66.33.60.129 and 76.76.21.142, "used by businesses like Spanish startup Tinybird, Hello Magazine, and others operating on Vercel, despite no affiliations with piracy in any form."
While clearly unhappy with how the company has been treated, Vercel says it's now working with LaLiga.

"We remain committed to providing fast, secure infrastructure for modern web applications. Likewise, we expect enforcement efforts to do the same: targeted, transparent, and technically sound. We are in contact with La Liga and are collaborating to remove illegal content in accordance with the court order. We're exploring mitigation strategies to restore access for Spanish users and continue to advocate for an open and permissionless web," Vercel concludes.

Man Buys Racetrack, Ends Up Launching the Netflix of Grassroots Motorsports 28

An anonymous reader quotes a report from Ars Technica: In 2019, Garrett Mitchell was already an Internet success. His YouTube channel, Cleetus McFarland, had over a million followers. If you perused the channel at that time, you would've found a range of grassroots motorsports videos with the type of vehicular shenanigans that earn truckloads of views. Some of those older videos include "BLEW BY A COP AT 120+mph! OOPS!," "THERE'S A T-REX ON THE TRACK!," and "Manual Transmission With Paddle Shifters!?!." Those videos made Mitchell, aka Cleetus McFarland, a known personality among automotive enthusiasts. But the YouTuber wanted more financial independence beyond the Google platform and firms willing to sponsor his channel. " after my YouTube was growing and some of my antics [were] getting videos de-monetized, I realized I needed a playground," Mitchell told Ars Technica in an email.

Mitchell found a road toward new monetization opportunities through the DeSoto Super Speedway. The Bradenton, Florida, track had changed ownership multiple times since opening in the 1970s. The oval-shaped racetrack is three-eighths of a mile long with 12-degree banking angles. By 2018, the track had closed its doors and was going unused. DeSoto happened to be next to Mitchell's favorite drag strip, giving the YouTuber the idea of turning it into a stadium where people could watch burnouts and other "massive, rowdy" ticketed events. Mitchell added: "So I sold everything I could, borrowed some money from my business manager, and went all in for [$]2.2 million." But like the rest of the world, Mitchell hit the brakes on his 2020 plans during COVID-19 lockdowns. Soon after his purchase, Mitchell couldn't use the track, renamed Freedom Factory, for large gatherings, forcing him to reconsider his plans. "We had no other option but to entertain the people somehow. And with no other racing goin' on anywhere, we bet big on making something happen. And it worked," Mitchell said. That "something" was a pay-per-view (PPV) event hosted from the Freedom Factory in April 2020.

The event led to others and, eventually, Mitchell running his own subscription video on demand (SVOD) service, FRDM+, which originally launched as Cleetervision in 2022. Today, a FRDM+ subscription costs $20 per month or $120 per year. A subscription provides access to an impressive library of automotive videos. Some are archived from Mitchell's YouTube channel. Other, exclusive videos feature content such as interviews with motorsports influencers and members of Mitchell's staff and crew, and outrageous motorsports stunts. You can watch videos from other influencers on FRDM+, and the business can also white-label its platform into other influencers' websites, too.
"Today, bandwidth isn't a problem for FRDM+, and navigating the streaming service doesn't feel much different from something like Netflix," writes Ars Technica's Scharon Harding. "There are different 'channels' (grouped together by related content or ongoing series) on top and new releases and upcoming content highlighted below. There are horizontal scrolling rows, and many titles have content summaries and/or trailers. The platform also has a support section with instructions for canceling subscriptions."

"Due to wildly differing audiences, markets, costs, and scales, comparing FRDM+'s financials to the likes of Netflix and other mainstream streaming services is like comparing apples to oranges. But it's interesting to consider that FRDM+ has achieved profitability faster than some of those services, like Peacock, which also launched in 2020, and Apple TV+, which debuted in 2019."

Apple Removes 'Available Now' Claim from Intelligence Page Following NAD Review (theverge.com) 21

Apple has quietly removed the "available now" designation from its Apple Intelligence marketing page following a National Advertising Division review. The change came after the NAD recommended Apple "discontinue or modify" the claim, which "reasonably conveyed the message" that all promoted AI features were immediately available with iPhone 16 devices.

The NAD, part of the Better Business Bureau, determined Apple's footnote explaining feature availability was "neither sufficiently clear and conspicuous nor close to the triggering claims."

EU Says It Will Enforce Digital Rules Irrespective of CEO and Location (reuters.com) 103

The European Union is determined to enforce its full digital rule book no matter who is in charge of companies such as X, Meta, Apple and Tiktok or where they are based, Commission President Ursula von der Leyen told Politico. From a report: "That's why we've opened cases against TikTok, X, Apple, Meta just to name a few. We apply the rules fairly, proportionally, and without bias. We don't care where a company's from and who's running it. We care about protecting people," Politico quoted von der Leyen as saying on Sunday. The EU's Digital Markets Act has been strongly criticised by the administration of U.S. President Donald Trump.

Space Investor Sees Opportunities in Defense-Related Startups and AI-Driven Systems (yahoo.com) 12

Chad Anderson is the founder/managing partner of the early-stage VC Space Capital (and an investor in SpaceX, along with dozens of other space companies). Space Capital produces quarterly reports on the space economy, and he says today, unlike 2021, "the froth is gone. But so is the hype. What's left is a more grounded — and investable — space economy."

On Yahoo Finance he shares several of the report's insights — including the emergence of "investable opportunities across defense-oriented startups in space domain awareness, AI-driven command systems, and hardened infrastructure." The same geopolitical instability that's undermining public markets is driving national urgency around space resilience. China's simulated space "dogfights" prompted the US Department of Defense to double down on orbital supremacy, with the proposed "Golden Dome" missile shield potentially unleashing a new wave of federal spending...

Defense tech is on fire, but commercial location-based services and logistics are freezing over. Companies like Shield AI and Saronic raised monster rounds, while others are relying on bridge financings to stay afloat...

Q1 also saw a breakout quarter for geospatial artificial intelligence (GeoAI). Software developer Niantic launched a spatial computing platform. SkyWatch partnered with GIS software supplier Esri. Planet Labs collaborated with Anthropic. And Xona Space Systems inked a deal with Trimble to boost precision GPS. This is the next leg of the space economy, where massive volumes of satellite data is finally made useful through machine learning, semantic indexing, and real-time analytics.

Distribution-layer companies are doing more with less. They remain underfunded relative to infrastructure and applications but are quietly powering the most critical systems, such as resilient communications, battlefield networks, and edge-based geospatial analysis. Don't let the low round count fool you; innovation here is quietly outpacing capital.

The article includes several predictions, insights, and possible trends (going beyond the fact that defense spending "will carry the sector...")
  • "AI's integration into space (across geospatial intelligence, satellite communications, and sensor fusion) is not a novelty. It's a competitive necessity."
  • "Focusing solely on rockets and orbital assets misses where much of the innovation and disruption is occurring: the software-defined layers that sit atop the physical backbone..."
  • "For years, SpaceX faced little serious competition, but that's starting to change." [He cites Blue Origin's progress toward approval for launching U.S. military satellites, and how Rocket Lab and Stoke Space "have also joined the competition for lucrative government launch contracts." Even Relativity Space may make a comeback, with former GOogle CEO Eric Schmidt acquiring a controlling stake.]
  • "An infrastructure reset is coming. The imminent ramp-up of SpaceX's Starship could collapse the cost structure for the infrastructure layer. When that happens, legacy providers with fixed-cost-heavy business models will be at risk. Conversely, capital-light innovators in station design, logistics, and in-orbit servicing could suddenly be massively undervalued."

The Bees Are Disappearing Again (seattletimes.com) 88

"Honeybee colonies are under siege across much of North America..." reported the New York Times last week. [Alternate URL here.] Last winter beekeepers across America "began reporting massive beehive collapses. More than half of the roughly 2.8 million colonies collapsed, costing the industry about $600 million in economic losses..."

America's Department of Agriculture says "sublethal exposure" to pesticides remains one of the biggest factors threatening honeybees, according to the article — but it's one of several threats. "Parasites, loss of habitat, climate change and pesticides threaten to wipe out as much as 70% or more of the nation's honeybee colonies this year, potentially the most devastating loss that the nation has ever seen." Some years are worse than others, but there has been a steady decline over time. Scientists have named the phenomenon colony collapse disorder: Bees simply disappear after they fly out to forage for pollen and nectar. Illness disables their radar, preventing them from finding their way home. The queen and her brood, if they survive, remain defenseless.

The precise causes remain unknown.

Bee colonies have become even more vulnerable because of the increase in extreme weather conditions, including droughts, heat waves, monster hurricanes, explosive wildfires and floods that have damaged or destroyed the bees and the vegetation they pollinate. If that isn't bad enough, parasites — and other creatures researchers refer to as "biotic" threats that prey on bees — proliferate when there is damage to ecosystems.

All that means that the U.S. beekeeping industry has contracted by about 2.9% over the past five years, according to data collected by IBISWorld, a research firm. Annual loss rates have been increasing among all beekeepers over the past decade with the most significant colony collapses in commercial operations happening during the past five years.

The article notes that "compounding the troubles for the bee industry are recent federal cuts" proposed by DOGE to America's Department of Agriculture, "where researchers were studying ways to protect the nation's honeybees." And while federal policies like tariffs could make farming more expensive, "Beekeepers also often depend on immigrants to manage their hives and to help produce commercial honey..."

US Chipmakers Fear Ceding China's AI Market to Huawei After New Trump Restrictions (msn.com) 99

The Trump administration is "taking measures to restrict the sale of AI chips by Nvidia, Advanced Micro Devices and Intel," especially in China, reports the New York Times. But that's triggered a series of dominoes. "In the two days after the limits became public, shares of Nvidia, the world's leading AI chipmaker, fell 8.4%. AMD's shares dropped 7.4%, and Intel's were down 6.8%." (AMD expects up to $800 million in charges after the move, according to CNBC, while NVIDIA said it would take a quarterly charge of about $5.5 billion.)

The Times notes hopeful remarks Thursday from Jensen Huang, CEO of Nvidia, during a meeting with the China Council for the Promotion of International Trade. "We're going to continue to make significant effort to optimize our products that are compliant within the regulations and continue to serve China's market." But America's chipmakers also have a greater fear, according to the article: "that their retreat could turn the Chinese tech giant Huawei into a global chip-making powerhouse." "For the U.S. semiconductor industry, China is gone," said Handel Jones, a semiconductor consultant at International Business Strategies, which advises electronics companies. He projects that Chinese companies will have a majority share of chips in every major category in China by 2030... Huang's message spoke to one of his biggest fears. For years, he has worried that Huawei, China's telecommunications giant, will become a major competitor in AI. He has warned U.S. officials that blocking U.S. companies from competing in China would accelerate Huawei's rise, said three people familiar with those meetings who spoke on the condition of anonymity.

If Huawei gains ground, Huang and others at Nvidia have painted a dark picture of a future in which China will use the company's chips to build AI data centers across the world for the Belt and Road Initiative, a strategic effort to increase Beijing's influence by paying for infrastructure projects around the world, a person familiar with the company's thinking said...

Nvidia's previous generation of chips perform about 40% better than Huawei's best product, said Gregory C. Allen, who has written about Huawei in his role as director of the Wadhwani AI Center at the Center for Strategic and International Studies. But that gap could dwindle if Huawei scoops up the business of its American rivals, Allen said. Nvidia was expected to make more than $16 billion in sales this year from the H20 in China before the restriction. Huawei could use that money to hire more experienced engineers and make higher-quality chips. Allen said the U.S. government's restrictions also could help Huawei bring on customers like DeepSeek, a leading Chinese AI startup. Working with those companies could help Huawei improve the software it develops to control its chips. Those kinds of tools have been one of Nvidia's strengths over the years.

TechRepublic identifies this key quote from an earlier article: "This kills NVIDIA's access to a key market, and they will lose traction in the country," Patrick Moorhead, a tech analyst with Moor Insights & Strategy, told The New York Times. He added that Chinese companies will buy from local rival Huawei instead.

Actors Who Sold AI Avatars Stuck In Black Mirror-Esque Dystopia (arstechnica.com) 16

Some actors who sold their likenesses to AI video companies like Synthesia now regret the decision, after finding their digital avatars used in misleading, embarrassing, or politically charged content. Ars Technica reports: Among them is a 29-year-old New York-based actor, Adam Coy, who licensed rights to his face and voice to a company called MCM for one year for $1,000 without thinking, "am I crossing a line by doing this?" His partner's mother later found videos where he appeared as a doomsayer predicting disasters, he told the AFP. South Korean actor Simon Lee's AI likeness was similarly used to spook naive Internet users but in a potentially more harmful way. He told the AFP that he was "stunned" to find his AI avatar promoting "questionable health cures on TikTok and Instagram," feeling ashamed to have his face linked to obvious scams. [...]

Even a company publicly committed to ethically developing AI avatars and preventing their use in harmful content like Synthesia can't guarantee that its content moderation will catch everything. A British actor, Connor Yeates, told the AFP that his video was "used to promote Ibrahim Traore, the president of Burkina Faso who took power in a coup in 2022" in violation of Synthesia's terms. [...] Yeates was paid about $5,000 for a three-year contract with Synthesia that he signed simply because he doesn't "have rich parents and needed the money." But he likely couldn't have foreseen his face being used for propaganda, as even Synthesia didn't anticipate that outcome.

Others may not like their AI avatar videos but consider the financial reward high enough to make up for the sting. Coy confirmed that money motivated his decision, and while he found it "surreal" to be depicted as a con artist selling a dystopian future, that didn't stop him from concluding that "it's decent money for little work." Potentially improving the climate for actors, Synthesia is forming a talent program that it claims will give actors a voice in decision-making about AI avatars. "By involving actors in decision-making processes, we aim to create a culture of mutual respect and continuous improvement," Synthesia's blog said.

China is banning automakers from using the terms "smart driving" and "autonomous driving" when they advertise driving assistance features, and it will tighten scrutiny of such technology upgrades. From a report: The mandate on vehicle advertising was delivered by the Ministry of Industry and Information Technology in its meeting with nearly 60 representatives from automakers on Wednesday, according to a transcript seen by Reuters and confirmed by one of the attendees. The move follows a fatal accident involving Xiaomi's best-selling SU7 sedan in March that triggered widespread concerns over vehicle safety.

LG TVs' Integrated Ads Get More Personal With Tech That Analyzes Viewer Emotions (arstechnica.com) 122

LG is partnering with Zenapse to integrate AI-driven emotional intelligence into its smart TVs, enabling hyper-targeted ads based on viewers' psychological traits, emotions, and behaviors. Ars Technica reports: The upcoming advertising approach comes via a multi-year licensing deal with Zenapse, a company describing itself as a software-as-a-service marketing platform that can drive advertiser sales "with AI-powered emotional intelligence." LG will use Zenapse's technology to divide webOS users into hyper-specific market segments that are supposed to be more informative to advertisers. LG Ad Solutions, LG's advertising business, announced the partnership on Tuesday.

The technology will be used to inform ads shown on LG smart TVs' homescreens, free ad-supported TV (FAST) channels, and elsewhere throughout webOS, per StreamTV Insider. LG will also use Zenapse's tech to "expand new software development and go-to-market products," it said. LG didn't specify the duration of its licensing deal with Zenapse. Zenapse's platform for connected TVs (CTVs), ZenVision, is supposed to be able to interpret the types of emotions shown in the content someone is watching on TV, partially by using publicly available information about the show's or movie's script and plot, StreamTV Insider reported. ZenVision also analyzes viewer behavior, grouping viewers based on their consumption patterns, the publication noted. Under the new partnership, ZenVision can use data that LG has gathered from the automatic content recognition software in LG TVs.

With all this information, ZenVision will group LG TV viewers into highly specified market segments, such as "goal-driven achievers," "social connectors," or "emotionally engaged planners," an LG spokesperson told StreamTV Insider. Zenapse's website for ZenVision points to other potential market segments, including "digital adopters," "wellness seekers," "positive impact & environment," and "money matters." Companies paying to advertise on LG TVs can then target viewers based on the ZenVision-specified market segments and deliver an "emotionally intelligent ad," as Zenapse's website puts it.

'We Are Not Programmed to Die,' Says Nobel Laureate Venki Ramakrishnan (wired.com) 86

In a recent interview with Wired, Nobel laureate Venkatraman Ramakrishnan discusses his book Why We Die, in which he argues that death is not genetically programmed but rather a consequence of evolution favoring reproduction over longevity. Here are some of the most thought-provoking excerpts: WIRED: Professor Ramakrishnan, the crucial question in your book is why we die. But exactly what is death?
Venki Ramakrishnan: By death, we mean the irreversible loss of the ability to function as a coherent individual. It is the result of the failure of a critical system or apparatus, for example, heart, brain, lung, or kidney failure. In this sense there is an apparent paradox: When our organism, as a whole, is alive, millions of cells within us are constantly dying, and we do not even realize it. On the other hand, at the time of death, most of the cells in our bodies are still alive, and entire organs are still functioning and can be donated to people in need of transplantation. But at that point the body has lost the ability to function as a whole. In this sense, it is therefore important to distinguish between cell death and death of the individual.

Speaking of death and aging, you say in your most recent book that you "wanted to offer an objective look at our current understanding of the two phenomena." What was the biggest surprise or most deeply held belief that you had to reconsider while writing and researching this work?
There have been several surprises, actually. One is that death, contrary to what one might think, is not programmed by our genes. Evolution does not care how long we live, but merely selects the ability to pass on our genes, a process known as "fitness" in evolutionary biology. Thus, the traits that are selected are those that help us survive childhood and reproduce. And it is these traits, later in life, that cause aging and decline. Another curious finding was the fact that aging is not simply due to wear and tear on cells. Wear and tear happens constantly in all living things, yet different species have very different lifespans. Instead, lifespan is the result of a balance between the expenditure of resources needed to keep the organism functioning and repairing it and those needed to make it grow, mature, and keep it healthy until it reproduces and nurtures offspring.

Do you think there is an aspect of the biology of aging that is still deeply misunderstood by the general public?
Certainly the indefinite extension of life. Although in principle there are no laws or constraints that prevent us from living much longer than we do currently, great longevity or "eternal youth" are still far off, and very significant obstacles to increasing our maximum life expectancy remain. We must also beware of the pseudoscience -- and business -- around the concepts of "anti-aging" or the "reversal of aging." These are often baseless concepts, unsupported by hard evidence, even though they may use language that sounds scientific. Unfortunately, we are all afraid of growing old and dying, so we are very sensitive to any claim that promises to help us avoid it. [...]

What do you think are the social and ethical implications of our desire to live longer?
Ever since we became aware of our mortality, we have desired to defeat aging and death. However, our individual desires may conflict with what is best for society. A society in which fertility rates are very low and lifespans are very high will be a stagnant society, with very slow generational turnover, and probably much less dynamic and creative. The Nobel Prize-winning South American novelist Mario Vargas Llosa, who recently passed away, expressed it best: "Old age on the one hand terrifies us, but when we feel anxious, it is important to remember how terrible it would be to live forever. If eternity were guaranteed, all the incentives and illusions of life would vanish. This thought can help us live old age in a better way."

Google Used AI To Suspend Over 39 Million Ad Accounts Suspected of Fraud (techcrunch.com) 25

An anonymous reader quotes a report from TechCrunch: Google on Wednesday said it suspended 39.2 million advertiser accounts on its platform in 2024 -- more than triple the number from the previous year -- in its latest crackdown on ad fraud. By leveraging large language models (LLMs) and using signals such as business impersonation and illegitimate payment details, the search giant said it could suspend a "vast majority" of ad accounts before they ever served an ad.

Last year, Google launched over 50 LLM enhancements to improve its safety enforcement mechanisms across all its platforms. "While these AI models are very, very important to us and have delivered a series of impressive improvements, we still have humans involved throughout the process," said Alex Rodriguez, a general manager for Ads Safety at Google, in a virtual media roundtable. The executive told reporters that a team of over 100 experts assembled across Google, including members from the Ads Safety team, the Trust and Safety division, and researchers from DeepMind.
"In total, Google said it blocked 5.1 billion ads last year and removed 1.3 billion pages," adds TechCrunch. "In comparison, it blocked over 5.5 billion ads and took action against 2.1 billion publisher pages in 2023. The company also restricted 9.1 billion ads last year, it said."

Canadian Math Prodigy Allegedly Stole $65 Million In Crypto (theglobeandmail.com) 85

A Canadian math prodigy is accused of stealing over $65 million through complex exploits on decentralized finance platforms and is currently a fugitive from U.S. authorities. Despite facing criminal charges for fraud and money laundering, he has evaded capture by moving internationally, embracing the controversial "Code is Law" philosophy, and maintaining that his actions were legal under the platforms' open-source rules. The Globe and Mail reports: Andean Medjedovic was 18 years old when he made a decision that would irrevocably alter the course of his life. In the fall of 2021, shortly after completing a master's degree at the University of Waterloo, the math prodigy and cryptocurrency trader from Hamilton had conducted a complex series of transactions designed to exploit a vulnerability in the code of a decentralized finance platform. The maneuver had allegedly allowed him to siphon approximately $16.5-million in digital tokens out of two liquidity pools operated by the platform, Indexed Finance, according to a U.S. court document.

Indexed Finance's leaders traced the attack back to Mr. Medjedovic, and made him an offer: Return 90 per cent of the funds, keep the rest as a so-called "bug bounty" -- a reward for having identified an error in the code -- and all would be forgiven. Mr. Medjedovic would then be free to launch his career as a white hat, or ethical, hacker. Mr. Medjedovic didn't take the deal. His social media posts hinted, without overtly stating, that he believed that because he had operated within the confines of the code, he was entitled to the funds -- a controversial philosophy in the world of decentralized finance known as "Code is Law." But instead of testing that argument in court, Mr. Medjedovic went into hiding. By the time authorities arrived on a quiet residential street in Hamilton to search his parents' townhouse less than two months later, Mr. Medjedovic had moved out, taking his electronic devices with him.

Then, roughly two years later, he struck again, netting an even larger sum -- approximately $48.4-million -- by conducting a similar exploit on another decentralized finance platform, U.S. authorities allege. Mr. Medjedovic, now 22, faces five criminal charges -- including wire fraud, attempted extortion and money laundering -- according to a U.S. federal court document that was unsealed earlier this year. If convicted, he could be facing decades in prison. First, authorities will have to find him.

China Halts Rare Earth Exports Globally (fortune.com) 361

Longtime Slashdot reader AmiMoJo shares the news that China has halted all rare earth exports globally -- including to the U.S., Japan, and Germany. Fortune reports: After Trump unveiled his "Liberation Day" tariffs on April 2, China retaliated on April 4 with its own duties as well as export controls on several rare earth minerals and magnets made from them. So far, those export controls have translated to a halt across the board, cutting off the U.S. and other countries, according to the New York Times. That's because any exports of the minerals and magnets now require special licenses, but Beijing has yet to fully establish a system for issuing them, the report said.

In the meantime, shipments of rare earths have been halted at many ports, with customs officials blocking exports to any country, including to the U.S. as well as Japan and Germany, sources told theÂTimes. China's Ministry of Commerce issued export restrictions alongside the General Administration of Customs, prohibiting Chinese businesses from any engagement with U.S. firms, especially defense contractors. While the Trump administration unveiled tariff exemptions on a range of key tech imports late Friday night, China's magnet exports were still halted through the weekend, industry sources told the Times. Beijing's export halt is notable because China has a stranglehold on global supplies of rare earths and magnets derived from them. They also represent an asymmetric advantage in that rare earths constitute a small share of China's exports but have an outsize impact on trade partners like the U.S., which relies on them as critical inputs for the auto, chip, aerospace, and defense industries.

VMware Revives Its Free ESXi Hypervisor (theregister.com) 70

VMware has resumed offering a free hypervisor. News of the offering emerged in a throwaway line in the Release Notes for version 8.0 Update 3e of the Broadcom business unit's ESXi hypervisor. From a report: Just below the "What's New" section of that document is the statement: "Broadcom makes available the VMware vSphere Hypervisor version 8, an entry-level hypervisor. You can download it free of charge from the Broadcom Support portal."

VMware offered a free version of ESXi for years, and it was beloved by home lab operators and vAdmins who needed something to tinker with. But in February 2024, VMware discontinued it on grounds that it was dropping perpetual licenses and moving to subscriptions.

Can AI Help Manage Nuclear Reactors? (msn.com) 63

America's Department of Energy launched a federally funded R&D center in 1946 called the Argonne National Laboratory, and its research became the basis for all of the world's commercial nuclear reactors.

But it's now developed an AI-based tool that can "help operators run nuclear plants," reports the Wall Street Journal, citing comments from a senior nuclear engineer in the lab's nuclear science and engineering division: Argonne's plan is to offer the Parameter-Free Reasoning Operator for Automated Identification and Diagnosis, or PRO-AID, to new, tech-forward nuclear builds, but it's also eyeing the so-called dinosaurs, some of which are being resurrected by companies like Amazon and Microsoft to help power their AI data centers. The global push for AI is poised to fuel a sharp rise in electricity demand, with consumption from data centers expected to more than double by the end of the decade, the International Energy Agency said Thursday. The owners of roughly a third of U.S. nuclear plants are in talks with tech companies to provide electricity for those data centers, the Wall Street Journal has reported.

PRO-AID performs real-time monitoring and diagnostics using generative AI combined with large language models that notify and explain to staff when something seems amiss at a plant. It also uses a form of automated reasoning — which uses mathematical logic to encode knowledge in AI systems — to mimic the way a human operator asks questions and comes to understand how the plant is operating [according to Richard Vilim, a senior nuclear engineer within the lab's nuclear science and engineering division].

The tool can also help improve the efficiency of the personnel needed to operate a nuclear plant, Vilim said. That's especially important as older employees leave the workforce. "If we can hand off some of these lower-level capabilities to a machine, when someone retires, you don't need to replace him or her," he said... Part of the efficiency in updating technology will come from consolidating the monitoring staff at a utility's nuclear plants at a single, centralized location — much as gas-powered plants already do.

It hasn't found its way into a commercial nuclear plant yet, the article acknowledges. But the senior nuclear engineer points out that America's newer gas-powered plants ended up being more automated with digital monitoring tools. Meanwhile the average age of America's 94 operating nuclear reactors is 42 years old, and "nearly all" of them have had their licenses extended, according to the article. (Those nuclear plants still provide almost 20% of America's electricity.)
