  • Chronic Ocean Heating Fuels 'Staggering' Loss of Marine Life, Study Finds
    by EditorDavid on 01/03/2026 at 9:39 pm

    Slashdot reader JustAnotherOldGuy shared this report from the Guardian: Chronic ocean heating is fuelling a "staggering and deeply concerning" loss of marine life, a study has found, with fish levels falling by 7.2% from as little as 0.1C of warming per decade. Researchers examined the year-to-year change of 33,000 populations in the northern hemisphere between 1993 and 2021, and isolated the effect of the decadal rate of seabed warming from short shifts such as marine heatwaves. They found the drop in biomass from chronic heating to be as high as 19.8% in a single year. "To put it simply, the faster the ocean floor warms, the faster we lose fish," said Shahar Chaikin, a marine ecologist at the National Museum of Natural Sciences in Spain and the study's lead author. "A 7.2% decline for every tenth of a degree per decade might sound small," he added. "But compounded over time, across entire ocean basins, it represents a staggering and deeply concerning loss of marine life." Read more of this story at Slashdot.

  • Anthropic's Claude Passes ChatGPT, Now #1, on Apple's 'Top Apps' Chart After Pentagon Controversy
    by EditorDavid on 01/03/2026 at 8:59 pm

    "Anthropic may have lost out on doing business with the US government," reports Engadget, "but it's gained enough popularity to earn the number one spot on the App Store's Top Free Apps leaderboard." Anthropic's Claude AI assistant had already leaped to the #2 slot on Apple's chart by late Friday," CNBC reported Saturday: The rise in popularity suggests that Anthropic is benefiting from its presence in news headlines, stemming from its refusal to have its models used for mass domestic surveillance or for fully autonomous weapons... OpenAI's ChatGPT sat at No. 1 on the App Store rankings on Saturday, while Google's Gemini was at No. 3... On Jan. 30, [Claude] was ranked No. 131 in the U.S., and it bounced between the top 20 and the top 50 for much of February, according to data from analytics company Sensor Tower... [And Friday night, for 85.3 million followers] pop singer Katy Perry posted a screenshot of Anthropic's Pro subscription for consumers, with a heart superimposed over it. Sunday Engadget reported Anthropic's "very public spat" with the Pentagon "led to a wave of user support that finally allowed Claude to dethrone OpenAI's ChatGPT on the App Store as the most downloaded free app." . Friday Anthropic posted "We are deeply grateful to our users, and to the industry peers, policymakers, veterans, and members of the public who have voiced their support in recent days. Thank you.

  • America Used Anthropic's AI for Its Attack On Iran, One Day After Banning It
    by EditorDavid on 01/03/2026 at 7:47 pm

    Engadget reports: In a lengthy post on Truth Social on February 27, President Trump ordered all federal agencies to "immediately cease all use of Anthropic's technology" following strong disagreements between the Department of Defense and the AI company. A few hours later, the U.S. conducted a major air attack on Iran with the help of Anthropic's AI tools, according to a report from The Wall Street Journal. Even Trump's post noted there would be a six-month phase-out for Anthropic's technology (adding that Anthropic "better get their act together, and be helpful during this phase out period, or I will use the Full Power of the Presidency to make them comply, with major civil and criminal consequences to follow.") Anthropic's Claude technology was also used by the U.S. military less than two months ago in its operation in Venezuela — reportedly making them the first AI developer known to be used in a classified U.S. War Department operation. The Wall Street Journal reported Anthropic's technology found its way into the mission through Anthropic's contract with Palintir. Read more of this story at Slashdot.

  • Americans Listen to Podcasts More Than Talk Radio Now, Study Shows
    by EditorDavid on 01/03/2026 at 6:34 pm

    "Podcasts have officially overtaken AM/FM talk radio as the more popular medium for spoken-word audio in the United States," reports TechCrunch, citing Edison Research's Share of Ear survey: The researchers have tracked these statistics over the last decade, and almost always, the percentage of time people spent listening to podcasts increased, while their time with spoken radio broadcasts decreased. For the first time this year, podcasts eclipsed spoken-word radio with 40% of listening time, as opposed to 39% for radio... We checked with Edison to see if these statistics include video podcasts, and they do. But the need to clarify that question points to the undeniable growing prevalence of video podcasts, hosted on platforms like Spotify and YouTube, which marks another key trend in podcasting... YouTube said that viewers watched 700 million hours of podcasts each month in 2025 on living room devices, like TVs, up from 400 million the previous year. Read more of this story at Slashdot.

  • North America's Bird Populations Are Shrinking Faster. Blame Climate Change and Agriculture
    by EditorDavid on 01/03/2026 at 5:34 pm

    "Billions fewer birds are flying through North American skies than decades ago," reports the Associated Press, "and their population is shrinking ever faster, mostly due to a combination of intensive agriculture and warming temperatures, a new study found." Nearly half of the 261 species studied showed big enough losses in numbers to be statistically significant and more than half of those declining are seeing their losses accelerate since 1987, according to Thursday's journal Science... The only consolation is that the birds that are shrinking in numbers the fastest are species — such as the European starling, American crow, grackle and house sparrow — with large enough populations that they aren't yet at risk of going extinct, said study lead author Francois Leroy, also an Ohio State ecologist... When it came to population declines — not the acceleration — the scientists noticed bigger losses further south. When they did a deeper analysis they statistically connected those losses to warmer temperatures from human-caused climate change. "In regions where temperatures increase the most, we are seeing strongest declines in populations," [said study co-author Marta Jarzyna, an ecologist at Ohio State University]. "On the other hand, the acceleration of those declines, that's mostly driven by agricultural practices." The scientists found statistical correlations between speeded-up decline rates and high fertilizer use, high pesticide use and amount of cropland, Leroy said. He said they couldn't say any of those caused the acceleration of losses, but it indicates agriculture in general is a factor. "The stronger the agriculture, the faster we will lose birds," said Leroy... McGill University wildlife biologist David Bird, who wasn't part of the study, said it was done well and that its conclusions made sense. With a growing human population, agriculture practices are intensified, more bird habitats are being converted to cropland, modern machinery often grind up nests and eggs and single crop plantings offer less possibilities for birds to find food and nests, said Bird, the editor of Birds of Canada. "The biggest impact of agricultural intensity though is our war on insects. Numerous recent studies have shown that insect populations in many places throughout the world, including the U.S., have crashed by well over 40 percent," Bird said in an email. "Many of the birds in this new study showing population declines depend heavily on insects for food." A 2019 study of the same bird species by Cornell University conservation scientist Kenneth Rosenberg also found that North America had 3 billion fewer birds than in 1970, the article points out.

  • Collabora Clashes With LibreOffice Over Move To Revive LibreOffice Online
    by EditorDavid on 01/03/2026 at 4:34 pm

    Slashdot reader darwinmac writes: The Document Foundation (TDF), the organization behind LibreOffice, has decided to bring back its LibreOffice Online project which been inactive since 2022. Collabora, a company that was a major contributor to the original LibreOffice Online, is not pleased with this development. After the original project went dormant, Collabora forked the code and created its own product, Collabora Online. Collaboras Michael Meeks, who also sits on the TDF board, reacted to the TDFs decision by saying that a fully supported, free online version already exists in the form of Collabora Online, and that resurrecting a dead repository makes little sense when an active, open community around the online suite already exists. For now, The Document Foundation plans to reopen the old repository for new contributions. The organization has issued a warning that the code is not ready for live deployment and users should wait until the development team confirms it is stable. Read more of this story at Slashdot.
