  • Did Virginia Regulators Downplay Data Center Health Concerns?
    by EditorDavid on 25/07/2026 at 11:00 pm

    Politico reports that in the Virginia area alone there's dozens of data center projects "that altogether need 70 gigawatts of power — equivalent to 70 nuclear plants" — currently seeking connection to their grid. But there's also concerns about a Virginia data center powered with natural gas and backup diesel generators: When Virginia's top environmental regulator received an analysis warning of data center pollution, it took him less than five minutes to forward it to seven people on his staff... Internal emails obtained by POLITICO through a public records request paint a portrait of an agency that moved quickly to defend the only data center in Virginia that is powering itself — in what former officials and environmental health advocates described as an unusual effort to shape the debate around an industry whose global epicenter is in the state. The agency's pushback focused on the report's findings that the facility in Loudoun County could release harmful amounts of air pollution through eight bus-sized natural gas turbines — as allowed by permits granted by the Department of Environmental Quality [DEQ] itself... The request comes as data centers are devising new ways to produce their own power as a way to temper growing public discord over rising electricity prices amid the AI construction boom. Virginia has more than 600 data centers. The report [commissioned by Virginia's 54-year-old environmental nonprofit Piedmont Environmental Council] raised concerns that the data center's on-site power system, which also includes dozens of backup diesel generators, could cause tens of millions of dollars in health damages to people living around the facility, owned by Vantage Data Centers... [The analysis also argued the pollution could lead to 3.4 to 6.5 premature deaths annually.] People living near the Vantage facility in Sterling say its natural gas turbines produce constant noise and air pollution. The permits for Vantage issued by DEQ in 2023 allow cumulative emissions of seven different pollutants, including 95 tons per year of nitrogen oxides and more than 56 tons of soot. Both contribute to asthma and heart attacks. Those figures are in line with other state permits for minor sources of pollution, but DEQ's permits for Vantage have sparked local concerns because of the facility's location in a residential area... [Viriginia environmental quality officials] raised questions about whether the report wrongly described the facility's potential air pollution as dangerous, when soot levels in Loudoun County are deemed acceptable by America's Environmental Protection Agency (EPA). Health experts, including former EPA air quality official Michael Korber, told POLITICO that soot pollution can negatively affect human health even at EPA-approved levels. The World Health Organization's standard for ambient soot pollution is nearly half of what EPA suggests is safe. Some current and former staffers on Virginia's Department of Environmental Quality believe it's inappropriate for the agency to issue aggressive statements on the healthfulness of the data centers, with one former department leader saying Virginia's DEQ "is not the health department."

  • Drying Lakebeds Are Releasing Massive Amounts of Carbon, Study Finds
    by EditorDavid on 25/07/2026 at 10:00 pm

    "In many parts of the world, lakes are drying out at a scale so massive that scientists are warning they may be emitting enough greenhouse gases to rival our fossil fuel habit," reports ScienceAlert: In a new study published in Science, scientists say the Aral Sea — the world's largest desiccated lake — has emitted a whopping 204 megatons (~225 million US tons) of carbon dioxide since it was drained in the 1960s... The study estimates that between 1960 and 2022, the evaporating sea has released 204 megatons of carbon dioxide into the atmosphere, based on site surveys and core samples collected from across the dry lakebed... The new study suggests that rehydrating the entire basin could come with enormous benefits to the environment, not just within the sea itself, but at a global level. "There is a hidden carbon treasure beneath the Aral Sea," says biochemist Rafael Marcé from the Spanish National Research Council. "If these sediments remain exposed, carbon will continue to be released into the atmosphere. If the sea is re-flooded, that same carbon could shift from being a source of emissions to becoming part of the climate solution." According to the researchers' calculations, re-flooding the lakebed could prevent the release of the estimated 165 megatons of carbon that remain. The study also revealed that nearly one-fifth of the Aral Sea's carbon emissions are actually being released as wind blows away sediment on the lakebed, a factor that researchers had not accounted for in the past.

  • Hyundai Claims Humanoid Robot Plan Is Not Part of Talks With Striking Workers
    by EditorDavid on 25/07/2026 at 9:00 pm

    Ars Technica reports: Hyundai Motor Company's plan to put humanoid robots to work by 2028 is not part of current negotiations with striking South Korean autoworkers, according to the company. The automaker is disputing news reports that partial labor strikes by the Hyundai Motor union at the world's largest automotive plant in South Korea were spurred by concerns about the company's planned deployment of humanoid robots in the United States starting in 2028. [The planned robots are built by Boston Dynamics, now a wholly-owned subsidiary of Hyundai.] A Hyundai statement shared with Ars describes the union's demands as focusing on compensation-related issues such as wage increases, bonuses, and an extension of workers' retirement age. "Potential deployment of robots in Korean production facilities is not part of the current labor-management discussions," according to the Hyundai statement... Hyundai emphasized that its current plan only covers the initial deployment of the Atlas humanoid robot at Metaplant America, an electric vehicle factory near Savannah, Georgia, starting in 2028. "Decisions about future Atlas deployment at other facilities will be made thoughtfully, in accordance with local operational needs, and in dialogue with the employees and workforce representatives at those sites," the company stated. However, The Wall Street Journal described the Hyundai Motor union as making "unprecedented demands seeking to enshrine job protections in the era of robots and AI," and characterized certain compensation demands as hedging against potential reductions in work hours caused by AI adoption and robotic automation. "Remember that without labor-management agreement, not a single robot using new technology will be allowed to enter the workplace," the union told Hyundai in an internal letter reported by Reuters. Hyundai management and the labor union are currently reviewing a proposed wage reform that would "provide factory workers with greater income stability even after the carmaker's planned deployment of humanoid robots," The Korea Times reported. But experts cautioned that the wage overhaul, which would convert hourly pay for overtime and night-shift allowances into fixed wages, could come at the expense of company productivity.

  • Amazon Cracks Down On Use of AI Images By Sellers
    by EditorDavid on 25/07/2026 at 8:00 pm

    CNBC reports: Amazon is requiring that third-party sellers label any product images or videos that contain "AI-generated people" after New York recently passed a law mandating greater transparency around "synthetic performers" in ads... The policy directs sellers to tag images [and videos or other graphics on listing pages] with specific metadata keywords before they're uploaded. "Recent legislation requires disclosure when images or videos in advertisements contain photorealistic AI-generated people," Amazon wrote in the announcement [clarifying that the requirement doesn't apply to content featuring TV/video game/movie characters or content including real people, even if they've been altered using AI]. The company said it will "add an indicator" to listings on its website, informing consumers that images or other content feature AI-generated people, "where applicable." It's unclear what criteria Amazon will apply when deciding when to display the label to shoppers... Amazon has embraced AI internally and it's increasingly infusing the technology across its portfolio. The company has optimized listing titles and details so they're more likely to be spotted by AI systems, invested in a recently rebranded assistant called Alexa for Shopping, and launched a feature that injects AI-generated [images of] products into its search bar in real time based on user queries. More Amazon third-party sellers are using AI to generate text, images and other content for their listings, partly by using the company's tools. Outside sellers account for more than 60% of goods sold on Amazon, the article points out. It adds that there's currently no nationwide U.S. law requiring companies to disclose AI-generated advertising content, it adds — but YouTube, Meta, Pinterest, and TikTok have already added labels for AI-generated content. And a new California law also requires large AI providers to embed watermarks in AI-generated images, video and other content... Read more of this story at Slashdot.

  • Top Online Sites Debate Cutting Off Google's Crawlers
    by EditorDavid on 25/07/2026 at 7:00 pm

    Futurism reports: [Some online publications] are now debating whether to cut Google off entirely, as the Wall Street Journal reports, illustrating an increasingly fraught relationship between the tech giant and the publishers that are creating content its AI models are regurgitating. According to the newspaper, prominent outlets including USA Today, Politico, the Economist, People, and Reuters are all reexamining their relationship with Google. Some are debating whether to continue to work with the tech giant at all... Even Reddit executives are reevaluating the company's $60 million-a-year contract that allows Google to train its AI models on user-submitted content on the platform. They've similarly watched as Google's AI features discourage users from navigating to Reddit... Beyond pondering whether to cut Google off, other publishers have resorted to suing the company, accusing it of illegally rehashing their intellectual property via AI summaries. It's an extremely undesirable position for publishers. By severing ties with the search giant, they could face even steeper declines in traffic. At the same time, there's seemingly little to gain from having Google's AIs crawl their content — and in the long term, it could guarantee their destruction. Two interesting data points from the article: "Last month, Cloudflare CEO Matthew Prince noticed that automated bot traffic had overtaken human traffic for the first time in the internet's history." "USA Today has seen its traffic from US users drop by almost half over the last year." Read more of this story at Slashdot.

  • China is Creating a Herd of 100 Elite Yak Clones
    by EditorDavid on 25/07/2026 at 6:00 pm

    CNN reports on yaks "designed and cloned" in secretive, high-altitude labs in Tibet — 2.4 miles (4,000 meters) above sea level. They're a critical part of the local economy, and researchers "hope to create an 'elite' herd of super-yaks, healthier and more fertile than their predecessors." Both domestic yaks and their wild cousins have been facing threats for years, with some rare subspecies at risk of disappearing entirely. Authorities in the southwestern Chinese region have poured tens of millions of dollars into boosting the yak industry in recent years — and they hope cloning can help. The first yak clone came in July 2025, Chinese state media hailing it as a breakthrough achievement that combined cloning with gene selection. More clones were born this spring — and researchers are now aiming to create a herd of more than 100 "elite" yak clones by 2028, boasting desired traits like faster growth and larger size. "This shows the technology has moved from a one-time success to a stable, mass-scale application," said Fang Shengguo, the project's scientific lead and director of the State Conservation Center for Gene Resources of Endangered Wildlife, according to state-run news agency Xinhua... Many experts acknowledge there are legitimate arguments for using cloning in conservation, and for gene selection in farming. But the ethical waters are murky, and any such project should have high levels of public transparency and accountability, said Lisa Moses, a veterinarian and bioethicist at Harvard Medical School. So far, much of the yak cloning project remains mysterious, with information largely limited to glowing state-media coverage... [S]ome scientists say these projects reduce our sense of urgency toward fixing the environment, and that we can't simply churn out clones while the planet burns. To truly enact change, they say, we have to continue addressing the root cause of the problem — restoring degraded habitats, lowering carbon emissions, cracking down on poaching, and more. But for others, "there is a strong feeling ... that traditional conservation is essentially failing now," Moses said. "What we've been doing for the last 100 years to try to stave off ecological destruction is not working.... The argument is, we don't have a choice," she added. "If we want to try to do something that will actually make a difference, we need to use these technologies, specifically synthetic biology, to essentially override evolution and change the fitness of the species for the environment that they live in." "History is littered with good intentions in the environment gone wrong," Moses said, "and I would argue that these technologies have even more unknowns than ones that we previously employed." The article points out that the number of wild yaks "dropped more than a third in the last 30 years, with just 10,000 to 20,000 individuals left, according to the Wildlife Conservation Society." The yaks are threatened by climate change and habitat degradation, "with warmer temperatures bringing invasive plant species and increased competition for resources... in one of the world's most inhospitable terrains."
