An anonymous reader quotes a report from the Associated Press: For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium, which forms the foundation of the marine food web and helps regulate the planet's climate, will decline sharply as seas heat up. A study published Monday in the journal Nature Microbiology found Prochlorococcus populations could shrink by as much as half in tropical oceans over the next 75 years if surface waters exceed about 82 degrees Fahrenheit (27.8 Celsius). Many tropical and subtropical sea surface temperatures are already trending above average and are projected to regularly surpass 86 degrees Fahrenheit (30 Celsius) over that same period.

"These are keystone species -- very important ones," said Francois Ribalet, a research associate professor at the University of Washington's School of Oceanography and the study's lead author. "And when a keystone species decreases in abundance, it always has consequences on ecology and biodiversity. The food web is going to change." Prochlorococcus inhabit up to 75% of Earth's sunlit surface waters and produce about one-fifth of the planet's oxygen through photosynthesis. More crucially, Ribalet said, they convert sunlight and carbon dioxide into food at the base of the marine ecosystem. "In the tropical ocean, nearly half of the food is produced by Prochlorococcus," he said. "Hundreds of species rely on these guys."

Though other forms of phytoplankton may move in and help compensate for the loss of oxygen and food, Ribalet cautioned they are not perfect substitutes. "Evolution has made this very specific interaction," he said. "Obviously, this is going to have an impact on this very unique system that has been established." The findings challenge decades of assumptions that Prochlorococcus would thrive as waters warmed. Those predictions, however, were based on limited data from lab cultures. For this study, Ribalet and his team tested water samples while traversing the Pacific over the course of a decade.

alternative_right shares a report from The Guardian: It has been estimated that during the height of the coronavirus pandemic 129bn disposable face masks, mostly made from polypropylene and other plastics, were being used every month around the world. With no recycling stream, most ended up either in landfill or littered in streets, parks, beaches, waterways and rural areas, where they have now begun to degrade. Recent research has reported a significant presence of disposable face masks in both terrestrial and aquatic environments.

They left newly bought masks of several different kinds for 24 hours in flasks containing 150ml of purified water, then filtered the liquid through a membrane to see what came out. Every mask examined ... leached microplastics, but it was the FFP2 and FFP3 masks -- marketed as the gold-standard protection against the transmission of the virus -- that leached the most, releasing four to six times as many. And they made an even more worrying discovery.

Subsequent chemical analysis of the leachate found medical masks also released bisphenol B, an endocrine-disrupting chemical that acts like oestrogen when absorbed into the bodies of humans and animals. Taking into account the total amount of single-use face masks produced during the height of the pandemic, the researchers estimated they led to the release of 128-214kg of bisphenol B into the environment. [The researchers wrote that "approximately 128â"214 kg of BPB were released into the environment each day from those masks."] The findings have been published in the journal Environmental Pollution.

In a new interview with The Telegraph (paywalled), William Shatner revealed he has never earned residuals from reruns of the original Star Trek series, since syndication royalties weren't in place until after the show ended in 1969. "Nobody knew about reruns," said Shatner. "The concept of syndication only came in after 'Star Trek' was canceled when someone from the unions said: 'Wait a minute, you're replaying all those films, those shows.' There was a big strike. But in the end, the unions secured residual fees shortly after 'Star Trek' finished, so I didn't benefit."

The now 94-year-old actor said he's actually only seen a "few" episodes of his work and has "never seen" any of the spinoffs. "I'm gonna tell you something that nobody knows. I've never seen another 'Star Trek' and I've seen as few 'Star Treks' of the show I was on, I've seen as few as possible," he told Entertainment Tonight. "I don't like to look at myself, and I've never seen any other. I love it, I think it's great. I just don't, you know, I don't watch television, per se."

Kevin Barry, founder and sole developer of Nova Launcher, has left parent company Branch Metrics after being told to stop work on both the launcher and an open-source release. While the app remains on Google Play, the launcher's website currently shows a 404 error. The Verge reports: Mobile analytics company Branch Metrics acquired Nova in 2022. The company's CEO at the time, co-founder Alex Austin, said on Reddit that if Barry were to leave Branch, "it's contracted that the code will be open-sourced and put in the hands of the community." Austin left Branch in 2023, and now with Barry officially gone from the company, too, it's unclear if the launcher will now actually be open-sourced.

"I think the newer leadership since Alex Austin left has put a different focus on the company and Nova simply isn't part of that focus in any way at all," Cliff Wade, Nova's former customer relations lead who left as part of the 2024 layoffs, tells The Verge. "It's just some app that they own but no longer feel they need or want." Wade also said that "I don't believe Branch will do the right thing any time soon with regards to open-sourcing Nova. I think they simply just don't care and don't want to invest time, unless of course, they get enough pressure from the community and individuals who care."

Users have started a change.org petition to ask for the project to be open-sourced, and Wade says it's a "great start" to apply that pressure. Wade said he hasn't personally seen Barry's contract, so couldn't corroborate the claim of a contractual obligation to open-source Nova. Still, he said that the community "deserves" for the launcher to be open-sourced. "Branch just simply needs to do the right thing here and honor what they as a company have stated as well as what then CEO Alex Austin has stated numerous times prior to him leaving Branch."

An anonymous reader shares a report: Two cultivated meat companies have filed a lawsuit against officials in Texas over the law that bans the sales of lab-grown meat in the state for two years. California-based companies UPSIDE Foods, which makes cultivated chicken, and Wildtype, which makes cultivated salmon are suing Attorney General Ken Paxton, Texas Department of State Health Services, Texas Health and Human Services, and Travis County, accusing them of government overreach.

"This law has nothing to do with protecting public health and safety and everything to do with protecting conventional agriculture from innovative out-of-state competition," said Paul Sherman, a senior attorney at the Institute for Justice, a nonprofit law firm that is representing UPSIDE Foods and Wildtype. "That is not a legitimate use of government power." In June, lawmakers passed Senate Bill 261, which bans the sale of lab-grown meat in Texas for two years. Lab-grown meat, also known as cell cultivated meat or cultured meat, is made from taking animal cells and growing them in an incubator or bioreactor until they form an edible product.

An anonymous reader shares a report: OpenAI recently had both good news and bad news for shareholders. Revenue growth from ChatGPT is accelerating at a more rapid rate than the company projected half a year ago. The bad news? The computing costs to develop artificial intelligence that powers the chatbot, and other data center-related expenses, will rise even faster.

As a result, OpenAI projected its cash burn this year through 2029 will rise even higher than previously thought, to a total of $115 billion. That's about $80 billion higher than the company previously expected. The unprecedented projected cash burn, which would add to the roughly $2 billion it burned in the past two years, helps explain why the company is raising more capital than any private company in history.

Slashdot reader Charlotte Web shared this report from the Register: Among the software developers who use Microsoft's GitHub, the most popular community discussion in the past 12 months has been a request for a way to block Copilot, the company's AI service, from generating issues and pull requests in code repositories. The second most popular discussion — where popularity is measured in upvotes — is a bug report that seeks a fix for the inability of users to disable Copilot code reviews. Both of these questions, the first opened in May and the second opened a month ago, remain unanswered, despite an abundance of comments critical of generative AI and Copilot...

The author of the first, developer Andi McClure, published a similar request to Microsoft's Visual Studio Code repository in January, objecting to the reappearance of a Copilot icon in VS Code after she had uninstalled the Copilot extension... "I've been for a while now filing issues in the GitHub Community feedback area when Copilot intrudes on my GitHub usage," McClure told The Register in an email. "I deeply resent that on top of Copilot seemingly training itself on my GitHub-posted code in violation of my licenses, GitHub wants me to look at (effectively) ads for this project I will never touch. If something's bothering me, I don't see a reason to stay quiet about it. I think part of how we get pushed into things we collectively don't want is because we stay quiet about it."

It's not just the burden of responding to AI slop, an ongoing issue for Curl maintainer Daniel Stenberg. It's the permissionless copying and regurgitation of speculation as fact, mitigated only by small print disclaimers that generative AI may produce inaccurate results. It's also GitHub's disavowal of liability if Copilot code suggestions happen to have reproduced source code that requires attribution. It's what the Servo project characterizes in its ban on AI code contributions as the lack of code correctness guarantees, copyright issues, and ethical concerns. Similar objections have been used to justify AI code bans in GNOME's Loupe project, FreeBSD, Gentoo, NetBSD, and QEMU... Calls to shun Microsoft and GitHub go back a long way in the open source community, but moved beyond simmering dissatisfaction in 2022 when the Software Freedom Conservancy (SFC) urged free software supporters to give up GitHub, a position SFC policy fellow Bradley M. Kuhn recently reiterated.
McClure says In the last six months their posts have drawn more community support — and tells the Register there's been a second change in how people see GitHub within the last month. After GitHub moved from a distinct subsidiary to part of Microsoft's CoreAI group, "it seems to have galvanized the open source community from just complaining about Copilot to now actively moving away from GitHub."

AI Overviews have lowered click-through traffic to Daily Mail sites by as much as 89%, the publisher told a UK government body that regulates competition. So they've joined other top news organizations (including Guardian Media Group and the magazine trade body the Periodical Publishers Association) in asking the regulators "to make Google more transparent and provide traffic statistics from AI Overview and AI Mode to publishers," reports the Guardian: Publishers — already under financial pressure from soaring costs, falling advertising revenues, the decline of print and the wider trend of readers turning away from news — argue that they are effectively being forced by Google to either accept deals, including on how content is used in AI Overview and AI Mode, or "drop out of all search results", according to several sources... In recent years, Google Discover, which feeds users articles and videos tailored to them based on their past online activity, has replaced search as the main source of click-throughs to content. However, David Buttle, founder of the consultancy DJB Strategies, says the service, which is also tied to publishers' overall search deals, does not deliver the quality traffic that most publishers need to drive their long-term strategies. "Google Discover is of zero product importance to Google at all," he says. "It allows Google to funnel more traffic to publishers as traffic from search declines ... Publishers have no choice but to agree or lose their organic search. It also tends to reward clickbaity type content. It pulls in the opposite direction to the kind of relationship publishers want."

Meanwhile, publishers are fighting a wider battle with AI companies seeking to plunder their content to train their large language models. The creative industry is intensively lobbying the government to ensure that proposed legislation does not allow AI firms to use copyright-protected work without permission, a move that would stop the "value being scraped" out of the £125bn sector. Some publishers have struck bilateral licensing deals with AI companies — such as the FT, the German media group Axel Springer, the Guardian and the Nordic publisher Schibsted with the ChatGPT maker OpenAI — while others such as the BBC have taken action against AI companies alleging copyright theft. "It is a two-pronged attack on publishers, a sort of pincer movement," says Chris Duncan, a former News UK and Bauer Media senior executive who now runs a media consultancy, Seedelta. "Content is disappearing into AI products without serious remuneration, while AI summaries are being integrated into products so there is no need to click through, effectively taking money from both ends. It is an existential crisis."
"At the moment the AI and tech community are showing no signs of supporting publisher revenue," says the chief executive of the UK's Periodical Publishers Association...

How do AI tools impact college students? 231 students in an object-oriented programming class participated in a study at Estonia's University of Tartu (conducted by an associate professor of informatics and a recently graduated master's student). They were asked how frequently they used AI tools and for what purposes. The data were analyzed using descriptive statistics, and Spearman's rank correlation analysis was performed to examine the strength of the relationships. The results showed that students mainly used AI assistance for solving programming tasks — for example, debugging code and understanding examples. A surprising finding, however, was that more frequent use of chatbots correlated with lower academic results. One possible explanation is that struggling students were more likely to turn to AI. Nevertheless, the finding suggests that unguided use of AI and over-reliance on it may in fact hinder learning.
The researchers say their report provides "quantitative evidence that frequent AI use does not necessarily translate into better academic outcomes in programming courses."

Other results from the survey:

• 47 respondents (20.3%) never used AI assistants in this course.

• Only 3.9% of the students reported using AI assistants weekly, "suggesting that reliance on such tools is still relatively low."

• "Few students feared plagiarism, suggesting students don't link AI use to it — raising academic concerns."

The blog OMG Ubuntu notes that Microsoft Copilot chatbot support has been added in the latest Firefox Nightly builds. "Firefox's sidebar already offers access to popular chatbots, including OpenAI's ChatGPT, Anthropic's Claude, Le Chat's Mistral and Google's Gemini. It previously offered HuggingChat too." As the testing bed for features Mozilla wants to add to stable builds (though not all make it — eh, rounded bottom window corners?), this is something you can expect to find in a future stable update... Copilot in Firefox offers the same features as other chatbots: text prompts, upload files or images, generate images, support for entering voice prompts (for those who fancy their voice patterns being analysed and trained on). And like those other chatbots, there are usage limits, privacy policies, and (for some) account creation needed. In testing, Copilot would only generate half a summary for a webpage, telling me it was too long to produce without me signing in/up for an account.

On a related note, Mozilla has updated stable builds to let third-party chatbots summarise web pages when browsing (in-app callout alerts users to the 'new' feature). Users yet to enable chatbots are subtly nudged to do so each time they right-click on web page. [Between "Take Screenshot" and "View Page Source" there's a menu option for "Ask an AI Chatbot."] Despite making noise about its own (sluggish, but getting faster) on-device AI features that are privacy-orientated, Mozilla is bullish on the need for external chatbots.
The article suggests Firefox wants to keep up with Edge and Chrome (which can "infuse first-party AI features directly.") But it adds that Firefox's nightly build is also testing some non-AI features, like new task and timer widgets on Firefox's New Tab page. And "In Firefox Labs, there are is an option to enable JPEG XL support, a super-optimised version of JPEG that is gaining traction (despite Google's intransigence).

Other Firefox news:

• There's good news "for users still clinging to Windows 7," writes the Register. Support for Firefox Extended Support Release 115 "is being extended until March 2026."

• Google "can keep paying companies like Mozilla to make Google the default search engine, as long as these deals aren't exclusive anymore," reports the blog It's FOSS News. (The judge wrote that "Cutting off payments from Google almost certainly will impose substantial — in some cases, crippling — downstream harms to distribution partners..." according to CNBC — especially since the non-profit Mozilla Foundation gets most of its annual revenue from its Google's search deal.)

• Don't forget you can now search your tabs, bookmarks and browsing history right from the address bar with keywords like @bookmarks, @tabs, and @history. (And @actions pulls up a list of actions like "Open private window" or "Restart Firefox").

"A raft of articles have been retracted from publications including Business Insider and Wired in recent month," reports the Washington Post, "with links between them suggesting a possible broader scheme to pass off fake stories that these outlets now suspect were written using artificial intelligence." A Washington Post probe into the retractions found a connection between Onyeka Nwelue, the purported author of one of 38 essays removed this week by Business Insider, and someone using the name Margaux Blanchard, two of whose stories were previously removed by the same outlet. In recent months SFGate, Index on Censorship and Wired also retracted articles under the Blanchard byline, after it was identified as bogus by the British publication Press Gazette...

Business Insider Editor in Chief Jamie Heller explained to staff Tuesday in an email, obtained by The Post, that the report of a phony writer spurred a fuller investigation that turned up dozens of suspicious articles under various bylines. "We recently learned that a freelance contributor misrepresented their identity in two first-person essays written for Business Insider. As soon as this came to light, we took down the essays and began an investigation," Heller said. "As part of this process, we've removed additional first-person essays from the site due to concerns about the authors' identity or veracity. No news articles or videos were found to have this issue." On Tuesday Business Insider removed 38 pieces that had been published under bylines other than Blanchard. Business Insider deleted the author pages of 19 individuals, including Blanchard and Nwelue, and replaced their essays with editor's notes.

The website's investigation involved reviewing "tens of thousands of records," Business Insider spokesperson Ari Isaacman D'Angelo said in a statement to The Post. But it hadn't determined whether artificial intelligence was used to produce the yanked essays, she said, noting that AI-detection tools are often unreliable... Essays under [Nate] Giovanni's byline feature contradictory information. One piece, published in December 2024, refers to the author having two teenage daughters and a two-and-a-half-year-old son. Another, published three months later mentions two sons, aged eight and nine. Pieces that ran in May and July — about house-sitting around the world and applying to PhD programs — make no mention of a family at all...

On Aug. 21, Wired wrote a longer mea culpa about the article it published under Blanchard's name, with the headline "How WIRED Got Rolled by an AI Freelancer." "If anyone should be able to catch an AI scammer, it's WIRED," the publication wrote. ["In fact we do, all the time. Our editors receive transparently AI-generated pitches on a regular basis, and we reject them accordingly..."] "Unfortunately, one got through," referring to a story that ran under Blanchard's byline in May about two people who were married in the video game Minecraft.
The site Index on Censorship also published an article under the Blanchard byline about threats to journalists in Guatemala. "In the age of very intelligent AI it's clear we will have to look at things differently," the site's editor told the Washington Post.

The Post's article notes that one sign the pitches were AI-generated "is that while they sounded interesting, they featured details that were erroneous — including fictitious locales." Reached for a comment, one of the authors told the Post "Don't mention my name in your stupid article," claiming their acocunt was recently "compromised" (though their X.com account had also recently tweeted one of their articles.) But another author emailed the Post from their actual academic email address, saying they had no connection to the Gmail account The Post had been corresponding with. And here's how the person at that Gmail account responded to a follow-up query from the Post.

"What is one to do? With a few savvy prompts, AI could probably generate a 'long-lost' novel by Proust."

In 2016 comedian Dave Chappelle made headlines by requiring concert attendees to lock their cellphones in a pouch to prevent recording.

Nine years later those pouches (made by tech startup Yondr) are required for at least 2.5 million students in America, reports CBS News, "and the company said the number could triple after the 2025 numbers are tallied in about three months... Students in 35 states, including New York, Florida, Texas, California, Massachusetts and Georgia, now contend with laws or rules limiting phones and other electronic devices in school."

For example, The Yonkers School District purchased about 11,000 pouches, according to the article, "to comply with the statewide mandate that bans phones in classrooms." The pouch, which students carry with them, is locked and unlocked using magnets affixed to the entrance of the school and outside the main office... ["Some students have reported long lines and disruption at their schools," the article notes later, "as they wait to open their pouches." But on the first day of school at Yonkers, one student said the lines actually went pretty smoothly, and they ended up having a live conversation with a friend during lunch and "felt human"...] Other students were not so enthralled by the pouch; some reported seeing classmates bypass the Yondr pouch by using their Apple watches, buying "burner" phones and putting them in the pouch, breaking the pouch and other tricks to get to their phones.

[Yondr CEO Graham] Dugoni acknowledged that there will always be some students who can figure out how to get around the restrictions. The purpose of the pouches, he said, was to create a culture change in a school and create an environment conducive to their learning and development. More than 70% of high school teachers in the U.S. say cellphones are a major classroom distraction, according to the Pew Research Center Center.
Yondr CEO Graham Dugoni uses a flip phone, the article points out, and says "Our whole perspective is that it's not taking something away from students, it's giving them something back."

He says his larger mission is to create chances for people "to experience life outside of a fully digital realm" — and that Yondr now has school partners in all 50 U.S. states, and in 45 different countries: The cost of buying the pouches — roughly $25-30 per student — has set off debates around how schools should be spending their limited budgets. It's a particular issue for districts struggling with crumbling infrastructure, limited textbooks and access to other technology needed to learn...Districts in various states have reported spending from $26,000 to over $370,000, with Cincinnati Schools saying they spent $500,000 to provide pouches for students in grades 7-12.

Announced this week at RustConf 2025 in Seattle, the new Rust Innovation Lab will offer open source projects "the opportunity to receive fiscal sponsorship from the Rust Foundation, including governance, legal, networking, marketing, and administrative support."

And their first project will be the TLS library Rustls (for cryptographic security), which they say "demonstrates Rust's ability to deliver both security and performance in one of the most sensitive areas of modern software infrastructure." Choosing Rustls "underscores the lab's focus on infrastructure-critical tools, where reliability is paramount," argues explains WebProNews. But "Looking ahead, the foundation plans to expand the lab's portfolio, inviting applications from promising Rust initiatives. This could catalyze innovations in areas like embedded systems and blockchain, where Rust's efficiency shines."

Their article notes that the Rust Foundation "sees the lab as a way to accelerate innovation while mitigating the operational burdens that often hinder open-source development." [T]he Foundation aims to provide a stable, neutral environment for select Rust endeavors, complete with governance oversight, legal and administrative backing, and fiscal sponsorship... At its core, the Rust Innovation Lab addresses a growing need within the developer community for structured support amid Rust's rising adoption in sectors like systems programming and web infrastructure. By offering a "home" for projects that might otherwise struggle with sustainability, the lab ensures continuity and scalability. This comes at a time when Rust's memory safety features are drawing attention from major tech firms, including those in cloud computing and cybersecurity, as a counter to vulnerabilities plaguing languages like C++...

Industry observers note that such fiscal sponsorship could prove transformative, enabling projects to secure funding from diverse sources while maintaining independence. The Rust Foundation's involvement ensures compliance with best practices, potentially attracting more corporate backers wary of fragmented open-source efforts... By providing a neutral venue, the foundation aims to prevent the pitfalls seen in other ecosystems, such as project abandonment due to maintainer burnout or legal entanglements... For industry insiders, the Rust Innovation Lab represents a strategic evolution, potentially accelerating Rust's integration into mission-critical systems.

Longtime Slashdot reader sinij shares a report from CBC News: Prime Minister Mark Carney is delaying a plan to force automakers to hit minimum sales levels for electric vehicles. The move is part of a series of measures the government announced Friday to help the sectors most affected by U.S. President Donald Trump's tariffs. The EV mandate will be paused as the government conducts a 60-day review of the policy, and will be waived for 2026 models. Sources told CBC News that the review will look at the entire mandate and next steps.

"We have an auto sector which, because of the massive change in U.S. policy, is under extreme pressure. We recognize that," Carney said at a news conference in Mississauga, Ont. "They've got enough on their plate right now. So we're taking that off." The government is using the review as part of broader look at all the government's climate measures, he added. [...]

Brian Kingston, president of the Canadian Vehicle Manufacturers' Association, called it "an important first step." "The EV mandate imposes unsustainable costs on auto manufacturers, putting at risk Canadian jobs and investment in this critical sector of the economy," he said in a statement. "A full repeal of the regulation is the most effective way to provide immediate relief to the industry and keep it competitive."

An anonymous reader quotes a report from Reuters: President Donald Trump said on Thursday his administration would impose tariffs on semiconductor imports from companies not shifting production to the U.S., speaking ahead of a dinner with major technology company CEOs. "Yeah, I have discussed it with the people here. Chips and semiconductors -- we will be putting tariffs on companies that aren't coming in. We will be putting a tariff very shortly," Trump said without giving an exact time or rate.

"We will be putting a very substantial tariff, not that high, but fairly substantial tariff with the understanding that if they come into the country, if they are coming in, building, planning to come in, there will not be a tariff," Trump told reporters. "If they are not coming in, there is a tariff," Trump said in his comments on semiconductors. "Like, I would say (Apple CEO) Tim Cook would be in pretty good shape," he added, as Cook sat across the table. Further reading: Trump Basks in Tech Leaders' Spending Vows at White House Dinner

Mozilla announced today that they will end 32-bit Linux support for Firefox in 2026, with version 144 being the last release and ESR 140 as the fallback option. Phoronix reports: Firefox has continued providing 32-bit Linux binaries even with most other web browsers and operating systems going all-in on x86_64 support. But given that 32-bit Linux support is waning by distributions and the vast majority of distributions aren't even shipping i686 install images anymore, they will be removing 32-bit Linux builds in 2026.

An anonymous reader quotes a report from Deadline: Anthropic has agreed to pay at least $1.5 billion into a class action fund as part of a settlement of litigation brought by a group of book authors. The sum, disclosed in a court filing on Friday, "will be the largest publicly reported copyright recovery in history, larger than any other copyright class action settlement or any individual copyright case litigated to final judgment," the attorneys for the authors wrote.

The settlement also includes a provision that releases Anthropic only for its conduct up the August 25, meaning that new claims could be filed over future conduct, according to the filing. Anthropic also has agreed to destroy the datasets used in its models. The settlement figure amounts to about $3,000 per class work, according to the filing. You can read the terms of Anthropic's copyright settlement here (PDF). A hearing in the case is scheduled for Sept. 8.

A first-of-its-kind global research expedition has extracted freshwater samples from beneath the Atlantic Ocean floor off Cape Cod, documenting a massive aquifer stretching from New Jersey to Maine. The three-month Expedition 501, funded at $25 million by the National Science Foundation and European Consortium for Ocean Research Drilling, drilled up to 1,289 feet into the seabed at sites 20-30 miles offshore.

Samples registered salinity as low as 1 part per thousand -- meeting U.S. freshwater standards -- with some readings even lower. Scientists collected nearly 50,000 liters for laboratory analysis to determine whether the water originates from ancient glacial melt or current terrestrial groundwater systems. The UN projects global freshwater demand will exceed supply by 40% within five years.

Networks of pipes and heat exchangers can transfer excess heat from buildings into nearby bodies of water -- but as the world warms, the cooling potential of some water courses is now diminishing, Wired reports. Paris's district cooling network, which pipes Seine river water to cool 800 buildings including the Louvre Museum, faces diminishing returns as climate change warms water temperatures. The system achieves coefficients of performance between 4 and 15 -- significantly higher than conventional air conditioning -- by transferring building heat through heat exchangers to the river. The Seine briefly exceeded 27C this summer, approaching the 30C regulatory limit for returned water.

The network currently spans 100 kilometers of pipes and will expand to 245 kilometers by 2042 to serve 3,000 buildings. Similar installations operate in Toronto using lake water from 83-meter depths and at Cornell University drawing 4C water from Lake Cayuga at 76 meters. Rotterdam and other cities are developing comparable systems as cooling demand rises.

An anonymous reader shares a report: Can AI help "smooth over" discussion on abortion, racism, immigration, or Israel-Palestine? Columbia University sure hopes so. The Verge has learned that the university recently began testing Sway, an AI debate program currently in beta. Developed by two researchers at Carnegie Mellon University, Sway matches up students with opposing views to chat one-on-one about hot-button issues and "facilitates better discussions between them," according to the tool's website. Nicholas DiBella, a postdoctoral scholar at CMU who helped develop Sway, told The Verge that about 3,000 students from more than 30 colleges and universities have used the tool.

One of those may soon be Columbia. News of the potential partnership comes after more than two years of escalating tensions at Columbia between students, administrators, and the federal government. The university has spent years at the center of controversy after controversy: expulsions of pro-Palestinian student protesters, a string of police raids, and demands from the federal government.

People at Columbia's Teachers College are testing Sway in order to potentially integrate it into the conflict resolution curriculum and "bridge-building initiatives at Columbia," DiBella said. He said there's also been interest from other teams at Columbia in using Sway for the fall 2026 semester and onward. Simon Cullen, an assistant professor at CMU and the other developer behind Sway, told The Verge that the company is also in touch with Columbia University Life.
