Gates Retreats From 'Doomsday' Climate View, Prioritizes Aid To Poorest Countries

Wed, 2025-10-29 14:00
Bill Gates is retreating from his earlier warnings about climate change. The Microsoft co-founder now argues that what he called the "doomsday view of climate change" has caused the climate community to focus too heavily on near-term emissions goals and divert resources from addressing poverty and disease in the world's poorest countries. In a blog post, Gates wrote that climate change will have serious consequences but will not lead to humanity's demise. He acknowledges that some climate advocates will call him a hypocrite given his own carbon footprint and his 2021 book warning that climate change could be as deadly as COVID-19 by mid-century and five times as deadly by 2100. The poorest countries receive less than 1% of rich countries' budgets at their highest level and that this share is shrinking as wealthy nations cut aid and low-income countries struggle with debt, he wrote. Rising temperatures are now inevitable and that the current consensus suggests Earth's average temperature will be between two and three degrees Celsius higher than 1850 levels by 2100.

Senator Blocks Trump-Backed Effort To Make Daylight Saving Time Permanent

Wed, 2025-10-29 13:00
An anonymous reader quotes a report from Politico: Sen. Tom Cotton wasn't fast enough in 2022 to block Senate passage of legislation that would make daylight saving time permanent. Three years later, he wasn't about to repeat that same mistake. The Arkansas Republican was on hand Tuesday afternoon to thwart a bipartisan effort on the chamber floor to pass a bill that would put an end to changing the clocks twice a year, including this coming Sunday. [...] A cross-party coalition of lawmakers has been trying for years to make daylight saving time the default, which would result in more daylight in the evening hours with less in the morning, plus bring to a halt to biannual clock adjustments. President Donald Trump endorsed the concept this spring, calling the changing of the clocks "a big inconvenience and, for our government, A VERY COSTLY EVENT!!!" His comments coincided with a hearing, then a markup, of Scott's legislation in the Senate Commerce Committee. It set off an intense lobbying battle in turn, pitting the golf and retail industries -- which are advocating for permanent daylight saving time -- against the likes of sleep doctors and Christian radio broadcasters -- who prefer standard time. "If permanent Daylight Savings Time becomes the law of the land, it will again make winter a dark and dismal time for millions of Americans," said Cotton in his objection to a request by Sen. Rick Scott (R-Fla.) to advance the bill by unanimous consent. "For many Arkansans, permanent daylight savings time would mean the sun wouldn't rise until after 8:00 or even 8:30am during the dead of winter," Cotton continued. "The darkness of permanent savings time would be especially harmful for school children and working Americans."

Early Reports Indicate Nvidia DGX Spark May Be Suffering From Thermal Issues

Wed, 2025-10-29 10:00
Longtime Slashdot reader zuki writes: According to a recent report over at Tom's Hardware, a number of those among early buyers who have been able to put the highly-coveted $4,000.00 DGX Spark mini-AI workstation through its paces are reporting throttling at 100W (rather than the advertised 240W capacity), spontaneous reboots, and thermal issues under sustained load. The workstation came under fire after John Carmack, the former CTO of Oculus VR, began raising questions about its real-world performance and power draw. "His comments were enough to draw tech support from Framework and even AMD, with the offer of an AMD-driven Strix Halo-powered alternative," reports Tom's Hardware. "What's causing this suboptimal performance, such as a firmware-level cap or thermal throttling, is not clear," the report adds. "Nvidia hasn't commented publicly on Carmack's post or user-reported instability. Meanwhile, several threads on Nvidia's developer forums now include reports of GPU crashes and unexpected shutdowns under sustained load."

China Pushes Boundaries With Animal Testing to Win Global Biotech Race

Wed, 2025-10-29 07:00
China is accelerating its biotech ambitions by pushing the limits of animal testing and gene editing (source paywalled; alternative source) while Western countries tighten ethical restrictions. "Editing the genes of large animals such as pigs, monkeys and dogs faces scant regulation in China," reports Bloomberg. "Meanwhile, regulators in the US and Europe demand layers of ethical reviews, rendering similar research involving large animals almost impossible." From the report: Backing the work of China's scientists is not only permissiveness but state money. In 2023 alone, the Chinese government funneled an estimated $3 billion into biotech. Its sales of cell and gene therapies are projected to reach $2 billion by 2033 from $300 million last year. On the Chinese researchers' side are government-supported breeding and research centers for gene-edited animals and a public largely in approval of pushing the boundaries of animal testing. The country should become "a global scientific and technology power," Xi said, declaring biotechnology and gene editing a strategic priority. For decades, the country's pharmaceutical companies specialized in generics, reproducing drugs already pioneered elsewhere. Delving head first into gene editing research may be key to China's plan to develop innovative drugs as well as reduce its dependence on foreign pharmaceutical companies. The result is a country that now dominates headlines with stories of large, genetically modified animals being produced for science -- and the catalog is startling. Its scientists have created monkeys with schizophrenia, autism and sleep disorders. They were the first to clone primates. They've engineered dogs with metabolic and neurological diseases, and even cloned a gene-edited beagle with a blood-clotting disorder.

Westinghouse Is Claiming a Nuclear Deal Would See $80 Billion of New Reactors

Wed, 2025-10-29 03:30
An anonymous reader quotes a report from Ars Technica: On Tuesday, Westinghouse announced that it had reached an agreement with the Trump administration that would purportedly see $80 billion of new nuclear reactors built in the US. And the government indicated that it had finalized plans for a collaboration of GE Vernova and Hitachi to build additional reactors. Unfortunately, there are roughly zero details about the deal at the moment. The agreements were apparently negotiated during President Trump's trip to Japan. An announcement of those agreements indicates that "Japan and various Japanese companies" would invest "up to" $332 billion for energy infrastructure. This specifically mentioned Westinghouse, GE Vernova, and Hitachi. This promises the construction of both large AP1000 reactors and small modular nuclear reactors. The announcement then goes on to indicate that many other companies would also get a slice of that "up to $332 billion," many for basic grid infrastructure. The report notes that no reactors are currently under construction and Westinghouse's last two projects ended in bankruptcy. According to the Financial Times, the government may share in profits and ownership if the deal proceeds.
