2026 Turing Award Goes To Inventors of Quantum Cryptography (nytimes.com) 8

Dave Knott shares a report from the New York Times: On Wednesday, the Association for Computing Machinery, the world's largest society of computing professionals, said Drs. Charles Bennett and Gilles Brassard had won this year's Turing Award for their work on quantum cryptography and related technologies. The Turing Award, which was introduced in 1966, is often called the Nobel Prize of computing, and it includes a $1 million prize, which the two scientists will share.

[...] The two met in 1979 while swimming in the Atlantic just off the north shore of Puerto Rico. They were taking a break while attending an academic conference in San Juan. Dr. Bennett swam up to Dr. Brassard and suggested they use quantum mechanics to create a bank note that could never be forged. Collaborating between Montreal and New York, they applied Dr. Bennett's idea to subway tokens rather than bank notes. In a research paper published in 1983, they showed that their quantum subway tokens could never be forged, even if someone managed to steal the subway turnstile housing the elaborate hardware needed to read them.

This led to quantum cryptography. After describing their new form of encryption in a research paper published in 1984, they demonstrated the technology with a physical experiment five years later. Called BB84, their system used photons -- particles of light -- to create encryption keys used to lock and unlock digital data. Thanks to the laws of quantum mechanics, the behavior of a photon changes if someone looks at it. This means that if anyone tries to steal the keys, he or she will leave a telltale sign of the attempted theft -- a bit like breaking the seal on an aspirin bottle.

Scientists Create Programmable, Autonomous Robots Smaller Than a Grain of Salt (upenn.edu) 46

Researchers at the University of Pennsylvania and University of Michigan "have created the world's smallest fully programmable, autonomous robots," according to a recent announcement.

The announcement calls them "microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each." Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices. Powered by light, the robots carry microscopic computers and can be programmed to move in complex patterns, sense local temperatures and adjust their paths accordingly... "We've made autonomous robots 10,000 times smaller," says Marc Miskin, Assistant Professor in Electrical and Systems Engineering at Penn Engineering and the papers' senior author. "That opens up an entirely new scale for programmable robots."
The announcement describes them as "the first truly autonomous, programmable robots at this scale" (as described in two recent academic articles). The team had to design a new propulsion system that utilized the unique locomotion physics in the microscopic realm, according to the university's announcement. So the robots "generate an electrical field that nudges ions in the surrounding solution." Those ions, in turn, push on nearby water molecules, animating the water around the robot's body. "It's as if the robot is in a moving river," says Miskin, "but the robot is also causing the river to move." The robots can adjust the electrical field that causes the effect, allowing them to move in complex patterns and even travel in coordinated groups, much like a school of fish, at speeds of up to one body length per second...

To be truly autonomous, a robot needs a computer to make decisions, electronics to sense its surroundings and control its propulsion, and tiny solar panels to power everything, and all that needs to fit on a chip that is a fraction of a millimeter in size. This is where David Blaauw's team at the University of Michigan came into action... The robots are programmed by pulses of light that also power them. Each robot has a unique address that allows the researchers to load different programs on each robot. "This opens up a host of possibilities," adds Blaauw, "with each robot potentially performing a different role in a larger, joint task."

YouTube's Sneaky AI 'Experiment': Is Social Media Embracing AI-Generated Content? (yahoo.com) 46

The Atlantic reports some YouTube users noticed their uploaded videos have since "been subtly augmented, their appearance changing without their creators doing anything..."

"For creators who want to differentiate themselves from the new synthetic content, YouTube seems interested in making the job harder." When I asked Google, YouTube's parent company, about what's happening to these videos, the spokesperson Allison Toh wrote, "We're running an experiment on select YouTube Shorts that uses image enhancement technology to sharpen content. These enhancements are not done with generative AI." But this is a tricky statement: "Generative AI" has no strict technical definition, and "image enhancement technology" could be anything. I asked for more detail about which technologies are being employed, and to what end. Toh said YouTube is "using traditional machine learning to unblur, denoise, and improve clarity in videos," she told me. (It's unknown whether the modified videos are being shown to all users or just some; tech companies will sometimes run limited tests of new features.)

While running this experiment, YouTube has also been encouraging people to create and post AI-generated short videos using a recently launched suite of tools that allow users to animate still photos and add effects "like swimming underwater, twinning with a lookalike sibling, and more." YouTube didn't tell me what motivated its experiment, but some people suspect that it has to do with creating a more uniform aesthetic across the platform. As one YouTube commenter wrote: "They're training us, the audience, to get used to the AI look and eventually view it as normal."

Google isn't the only company rushing to mix AI-generated content into its platforms. Meta encourages users to create and publish their own AI chatbots on Facebook and Instagram using the company's "AI Studio" tool. Last December, Meta's vice president of product for generative AI told the Financial Times that "we expect these AIs to actually, over time, exist on our platforms, kind of in the same way that [human] accounts do...."

This is an odd turn for "social" media to take. Platforms that are supposedly based on the idea of connecting people with one another, or at least sharing experiences and performances — YouTube's slogan until 2013 was "Broadcast Yourself" — now seem focused on getting us to consume impersonal, algorithmic gruel.

'Edge of Space' Skydiver Felix Baumgartner Dies in Paragliding Accident (go.com) 38

Felix Baumgartner has died. He was 56.

In 2012 Slashdot extensively covered the skydiver's "leap from the edge of space." ABC News remembers it as a Red Bull-financed stunt that involved "diving 24 miles from the edge of space, in a plummet that reached a speed of more than 500 mph." Baumgartner recalled the legendary jump in the documentary, "Space Jump," and said, "I was the first human being outside of an aircraft breaking the speed of sound and the history books. Nobody remembers the second one...."

Baumgartner, also known as "Fearless Felix," accomplished many records in his career, including setting the world record for highest parachute jump atop the Petronas Towers in Malaysia, flying across the English Channel in a wingsuit in 2003, and base jumping from the 85-foot arm of the Christ the Redeemer statue in Brazil in 2007.

"Baumgartner's altitude record stood for two years," remembers the Los Angeles Times, "until Google executive Alan Eustace set new marks for the highest free-fall jump and greatest free-fall distance."

They report that Baumgartner died Thursday "while engaged in a far less intense activity, crashing into the side of a hotel swimming pool while paragliding in Porto Sant Elpidio, a town on central Italy's eastern coast." More details from the Associated Press: "It is a destiny that is very hard to comprehend for a man who has broke all kinds of records, who has been an icon of flight, and who traveled through space," Mayor Massimiliano Ciarpella told The Associated Press.Ciarpella said that Baumgartner had been in the area on vacation, and that investigators believed he may have fallen ill during the fatal flight... Baumgartner, a former Austrian military parachutist, made thousands of jumps from planes, bridges, skyscrapers and famed landmarks...
ABC News remembers that in 2022 Baumgartner wrote in Newsweek that "Since I was a little kid, I've always looked up to people who left a footprint on this planet... now I think I have left a footprint...

"I believe big dreamers always win."

Paleontologists Identify Tiny Three-Eyed 'Sea Moth' Predator in Fossils (ground.news) 8

"With the help of more than five dozen fossils, paleontologists have uncovered a tiny three-eyed predator nicknamed the 'sea moth'," reports CNN, "that swam in Earth's oceans 506 million years ago."

Tiny as in 15 to 61 mm in total body length. (That's 0.60 to 2.4 inches...) But check out the illustration in CNN's article... Mosura fentoni, as the species is known, belongs to a group called radiodonts, an early offshoot of the arthropod evolutionary tree, according to a new study published Tuesday in the journal Royal Society Open Science. While radiodonts are now extinct, studying their fossilized remains can illuminate how modern arthropods such as insects, spiders and crabs evolved. One of the most diverse animal groups, arthropods are believed to account for more than 80% of living animal species, said lead study author Dr. Joe Moysiuk, curator of paleontology and geology at the Manitoba Museum in Winnipeg.

Well-preserved specimens of the previously unknown Mosura fentoni also reveal something that's never been seen in any other radiodont: an abdomen-like body region with 16 segments that include gills at its rear. This part of the creature's anatomy is similar to a batch of segments bearing respiratory organs at the rear of the body found in distant modern radiodont relatives like horseshoe crabs, woodlice and insects, Moysiuk said.... No animal living today quite looks like Mosura fentoni, Moysiuk said, although it had jointed claws similar to those of modern insects and crustaceans. But unlike those critters, which can have two or four additional eyes used to help maintain orientation, Mosura had a larger and more conspicuous third eye in the middle of its head.

"Although not closely related, Mosura probably swam in a similar way to a ray, undulating its multiple sets of swimming flaps up and down, like flying underwater," Moysiuk said in an email. "It also had a mouth shaped like a pencil sharpener and lined with rows of serrated plates, unlike any living animal." About the size of an adult human's index finger, Mosura and its swimming flaps vaguely resemble a moth, which led researchers to call it the "sea moth."

The Royal Society publication notes the etymology of the species name (Mosura fentoni is "from the name of the fictional Japanese monster, or kaiju... also known as 'Mothra'...in reference to the moth-like appearance of the animal."

Open Source Advocate Argues DeepSeek is 'a Movement... It's Linux All Over Again' (infoworld.com) 33

Matt Asay answered questions from Slashdot readers in 2010 (as the then-COO of Canonical). He currently runs developer relations at MongoDB (after holding similar positions at AWS and Adobe).

This week he contributed an opinion piece to InfoWorld arguing that DeepSeek "may have originated in China, but it stopped being Chinese the minute it was released on Hugging Face with an accompanying paper detailing its development." Soon after, a range of developers, including the Beijing Academy of Artificial Intelligence (BAAI), scrambled to replicate DeepSeek's success but this time as open source software. BAAI, for its part, launched OpenSeek, an ambitious effort to take DeepSeek's open-weight models and create a project that surpasses DeepSeek while uniting "the global open source communities to drive collaborative innovation in algorithms, data, and systems."

If that sounds cool to you, it didn't to the U.S. government, which promptly put BAAI on its "baddie" list. Someone needs to remind U.S. (and global) policymakers that no single country, company, or government can contain community-driven open source... DeepSeek didn't just have a moment. It's now very much a movement, one that will frustrate all efforts to contain it. DeepSeek, and the open source AI ecosystem surrounding it, has rapidly evolved from a brief snapshot of technological brilliance into something much bigger — and much harder to stop. Tens of thousands of developers, from seasoned researchers to passionate hobbyists, are now working on enhancing, tuning, and extending these open source models in ways no centralized entity could manage alone.

For example, it's perhaps not surprising that Hugging Face is actively attempting to reverse engineer and publicly disseminate DeepSeek's R1 model. Hugging Face, while important, is just one company, just one platform. But Hugging Face has attracted hundreds of thousands of developers who actively contribute to, adapt, and build on open source models, driving AI innovation at a speed and scale unmatched even by the most agile corporate labs.

Hugging Face by itself could be stopped. But the communities it enables and accelerates cannot. Through the influence of Hugging Face and many others, variants of DeepSeek models are already finding their way into a wide range of applications. Companies like Perplexity are embedding these powerful open source models into consumer-facing services, proving their real-world utility. This democratization of technology ensures that cutting-edge AI capabilities are no longer locked behind the walls of large corporations or elite government labs but are instead openly accessible, adaptable, and improvable by a global community.

"It's Linux all over again..." Asay writes at one point. "What started as the passion project of a lone developer quickly blossomed into an essential, foundational technology embraced by enterprises worldwide," winning out "precisely because it captivated developers who embraced its promise and contributed toward its potential."

We are witnessing a similar phenomenon with DeepSeek and the broader open source AI ecosystem, but this time it's happening much, much faster...

Organizations that cling to proprietary approaches (looking at you, OpenAI!) or attempt to exert control through restrictive policies (you again, OpenAI!) are not just swimming upstream — they're attempting to dam an ocean. (Yes, OpenAI has now started to talk up open source, but it's a long way from releasing a DeepSeek/OpenSeek equivalent on GitHub.)

Climate Crisis Has Tripled Length of Deadly Ocean Heatwaves, Study Finds (theguardian.com) 67

The climate crisis has tripled the length of ocean heatwaves, a study has found, supercharging deadly storms and destroying critical ecosystems such as kelp forests and coral reefs. From a report: Half of the marine heatwaves since 2000 would not have happened without global heating, which is caused by burning fossil fuels. The heatwaves have not only become more frequent but also more intense: 1C warmer on average, but much hotter in some places, the scientists said.

The research is the first comprehensive assessment of the impact of the climate crisis on heatwaves in the world's oceans, and it reveals profound changes. Hotter oceans also soak up fewer of the carbon dioxide emissions that are driving temperatures up. "Here in the Mediterranean, we have some marine heatwaves that are 5C hotter," said Dr Marta Marcos at the Mediterranean Institute for Advanced Studies in Mallorca, Spain, who led the study. "It's horrible when you go swimming. It looks like soup."

As well as devastating underwater ecosystems such as sea grass meadows, Marcos said: "Warmer oceans provide more energy to the strong storms that affect people at the coast and inland."

'Snowball Earth' Evolution Hypothesis Gains New Momentum (quantamagazine.org) 42

The University of Colorado Boulder's magazine recently wrote: What happened during the "Snowball Earth" period is perplexing: Just as the planet endured about 100 million years of deep freeze, with a thick layer of ice covering most of Earth and with low levels of atmospheric oxygen, forms of multicellular life emerged. Why? The prevailing scientific view is that such frigid temperatures would slow rather than speed evolution. But fossil records from 720 to 635 million years ago show an evolutionary spurt preceding the development of animals...

Carl Simpson, a macroevolutionary paleobiologist at CU Boulder, has found evidence that cold seawater could have jump-started — rather than suppressed — evolution from single-celled to multicellular life forms.

That evidence is described in Quanta magazine: Simpson proposes an answer linked to a fundamental physical fact: As seawater gets colder, it gets more viscous, and therefore more difficult for very small organisms to navigate. Imagine swimming through honey rather than water... To test the idea, Simpson, a paleobiologist at the University of Colorado, Boulder, and his team conducted an experiment designed to see what a modern single-celled organism does when confronted with higher viscosity... In an enormous, custom-made petri dish, [grad student Andrea] Halling and Simpson created a bull's-eye target of agar gel — their own experimental gauntlet of viscosity. At the center, it was the standard viscosity used for growing these algae in the lab. [Green algae, which swims with a tail-like flagellum.] Moving outward, each concentric ring had higher and higher viscosity, finally reaching a medium with four times the standard level. The scientists placed the algae in the middle, turned on a camera, and left them alone for 30 days — enough time for about 70 generations of algae to live, swim around for nutrients and die...

After 30 days, the algae in the middle were still unicellular. As the scientists put algae from thicker and thicker rings under the microscope, however, they found larger clumps of cells. The very largest were wads of hundreds. But what interested Simpson the most were mobile clusters of four to 16 cells, arranged so that their flagella were all on the outside. These clusters moved around by coordinating the movement of their flagella, the ones at the back of the cluster holding still, the ones at the front wriggling.

"One thing that you learn about small organisms from a physics point of view is that they don't experience the world the same way that we do, as larger-bodied organisms," Simpson says in the university's article. It says that instead unicellular organisms are specifically "affected by the viscosity, or thickness, of sea water," and Simpson adds that "basically, that would trigger the origin of animals, potentially."

Last year Simpson posted a preprint on biorxiv.org. (And he also co-authored an article on "physical constraints during Snowball Earth drive the evolution of multicellularity.")

There's a video showing algae in Simpson's lab clumping together in viscous water. "This observed behavior adds evidence to Simpson's hypothesis that single-celled organisms clumped together to their mutual advantage during the 'Snowball Earth' period," says the video's description, "thus adding momentum to the rise of multicellular organisms." But Simpson says in the university's article, "To actually see it empirically means there's something to this idea."

Simpson and colleagues have now received a $1 million grant to study grains of sand made from calcium carbonate and called ooids, since their diameter "could be a proxy measurement of Earth's temperature for the last 2.5 billion years," according to the university's article. Geologist Lizzy Trower says the research "can tell us something about the chemistry and water temperature in which they formed." And more importantly, "Does the fossil record agree with the predictions we would make based on this theory from this new record of temperature?" Trower and Simpson's work also has potential implications for the human quest to find life elsewhere in the universe, Trower said. If extremely harsh and cold environments can spur evolutionary change, "then that is a really different type of thing to look for in exoplanets (potentially life-sustaining planets in other solar systems), or think about when and where (life) would exist."

Signal is More Than Encrypted Messaging. It Wants to Prove Surveillance Capitalism Is Wrong (wired.com) 70

Slashdot reader echo123 shared a new article from Wired titled "Signal Is More Than Encrypted Messaging. Under Meredith Whittaker, It's Out to Prove Surveillance Capitalism Wrong." ("On its 10th anniversary, Signal's president wants to remind you that the world's most secure communications platform is a nonprofit. It's free. It doesn't track you or serve you ads. It pays its engineers very well. And it's a go-to app for hundreds of millions of people.") Ten years ago, WIRED published a news story about how two little-known, slightly ramshackle encryption apps called RedPhone and TextSecure were merging to form something called Signal. Since that July in 2014, Signal has transformed from a cypherpunk curiosity — created by an anarchist coder, run by a scrappy team working in a single room in San Francisco, spread word-of-mouth by hackers competing for paranoia points — into a full-blown, mainstream, encrypted communications phenomenon... Billions more use Signal's encryption protocols integrated into platforms like WhatsApp...

But Signal is, in many ways, the exact opposite of the Silicon Valley model. It's a nonprofit funded by donations. It has never taken investment, makes its product available for free, has no advertisements, and collects virtually no information on its users — while competing with tech giants and winning... Signal stands as a counterfactual: evidence that venture capitalism and surveillance capitalism — hell, capitalism, period — are not the only paths forward for the future of technology.

Over its past decade, no leader of Signal has embodied that iconoclasm as visibly as Meredith Whittaker. Signal's president since 2022 is one of the world's most prominent tech critics: When she worked at Google, she led walkouts to protest its discriminatory practices and spoke out against its military contracts. She cofounded the AI Now Institute to address ethical implications of artificial intelligence and has become a leading voice for the notion that AI and surveillance are inherently intertwined. Since she took on the presidency at the Signal Foundation, she has come to see her central task as working to find a long-term taproot of funding to keep Signal alive for decades to come — with zero compromises or corporate entanglements — so it can serve as a model for an entirely new kind of tech ecosystem...

Meredith Whittaker: "The Signal model is going to keep growing, and thriving and providing, if we're successful. We're already seeing Proton [a startup that offers end-to-end encrypted email, calendars, note-taking apps, and the like] becoming a nonprofit. It's the paradigm shift that's going to involve a lot of different forces pointing in a similar direction."

Key quotes from the interview:
  • "Given that governments in the U.S. and elsewhere have not always been uncritical of encryption, a future where we have jurisdictional flexibility is something we're looking at."
  • "It's not by accident that WhatsApp and Apple are spending billions of dollars defining themselves as private. Because privacy is incredibly valuable. And who's the gold standard for privacy? It's Signal."
  • "AI is a product of the mass surveillance business model in its current form. It is not a separate technological phenomenon."
  • "...alternative models have not received the capital they need, the support they need. And they've been swimming upstream against a business model that opposes their success. It's not for lack of ideas or possibilities. It's that we actually have to start taking seriously the shifts that are going to be required to do this thing — to build tech that rejects surveillance and centralized control — whose necessity is now obvious to everyone."

Wind Turbine Blade Breaks, Washes Ashore. Power Production Shut Down as Company Faces Investigation and Litigation (cnn.com) 138

"More pieces of a broken wind turbine off the coast of Massachusetts are falling into the Atlantic Ocean," reports CBS News on Thursday. "The CEO of Vineyard Wind was at Nantucket's Select Board meeting Wednesday evening, apologizing and answering questions about the initial break when he suddenly had to leave because the situation is getting worse."

CNN reports the debris has been "prompting beach closures and frustrating locals at the peak of the summer season" since the blade broke a week ago, and then folded over: Since then, foam debris and fiberglass — including some large and dangerously sharp pieces — have washed onto beaches. A "significant part" of the remaining damaged blade detached from the turbine early Thursday morning, Vineyard Wind said in a news release. The US Coast Guard confirmed to CNN it has located a 300-foot piece of the blade.

There are few answers to what caused the turbine to fail, and the incident has prompted questions and anger from city officials and Nantucket residents... The shards of turbine forced officials to close beaches earlier this week, though they have since reopened. [Nantucket select board chair Brooke Mohr] said the town would monitor for additional debris and adjust schedules accordingly. "Public safety is our most immediate concern, these fiberglass pieces are quite sharp," Mohr said, making swimming unsafe...

The federal government is conducting its own investigation and has ordered Vineyard Wind to stop all its wind turbines producing electricity until it can be determined whether any other blades were impacted, a Bureau of Safety and Environmental Enforcement spokesperson said in a statement. The federal government has also ordered the companies to preserve any equipment that could help determine the cause of the failure. The federal suspension order effectively halts further construction on Vineyard Wind, the first large-scale wind farm being installed in the US. The wind farm, a joint venture of Avangrid and Copenhagen Infrastructure Partners, has 10 turbines up and running so far with plans to install 62 total...

The project was set to double the number of turbines spinning off the East Coast, and state leaders in Massachusetts have viewed it as a big boost to the state's ability to generate electricity. Now the project is in limbo, and could remain so until the investigation is complete.

The article quotes the head of government affairs at wind blade manufacturer GE Vernova as saying a breaking wind turbine is "highly unusual and rare." But Vineyard Wind CEO Klaus Skoust Møller called it a "very serious situation" and apologized to local residents.

Meanwhile, the Boston Herald reported Friday that the Nantucket Select Board "is set to pursue litigation against the wind energy company in connection to the blade failure..." Town officials, residents and local mariners have all said they didn't learn of the incident until Monday evening, roughly 48 hours after the fact and just hours before debris started to wash ashore, prompting beaches to close Tuesday...

The "significant portion" of the 107-meter blade that detached from the turbine Thursday morning sunk to the ocean floor. Crews were slated to recover the fiberglass "in due course," town officials wrote in a Friday update... Residents are not taking kindly to Vineyard Wind's assertion that the debris — fiberglass fragments ranging in size from small pieces to larger sections, typically green or white — is not toxic. Vineyard Wind has deployed a crew of 56 contractors to assist in the cleanup of the island's beaches, and town officials said Friday that no town staff are actively engaged in removing the debris. The wind energy company reported Wednesday that crews had removed 17 cubic yards of debris, enough to fill more than six truckloads.

"The joint venture of Connecticut-based Avangrid and Denmark-based Copenhagen Infrastructure Partners is developing a plan to test water quality around the island while working on a process for financial claims."

Early Morning Frost Spotted On Some of Mars' Huge Mountains (theguardian.com) 50

Scientists have discovered early morning frost on the summits of Martian volcanoes near the planet's equator, indicating that water ice forms overnight in colder months and evaporates after sunrise. "While the frosty layer is exceptionally thin, it covers an enormous area," reports The Guardian. "Scientists calculate that in the more frigid Martian seasons, 150,000 tons of water, equivalent to 60 Olympic swimming pools, condense daily on the tops of the towering mountains." From the report: "It's the first time we've discovered water frost on the volcano summits and the first time we've discovered water frost in the equatorial regions of Mars," said Adomas Valantinas, a planetary scientist at the University of Berne in Switzerland and Brown University in the US. "What we're seeing could be a trace of a past Martian climate," Valantinas said of the frost-tipped volcanoes. "It could be related to atmospheric climate processes that were operating earlier in Martian history, maybe millions of years ago."

Valantinas spotted the frost-capped volcanoes in high-resolution colour images snapped in the early morning hours on Mars by the European Space Agency's Trace Gas Orbiter (TGO). With colleagues, he confirmed the discovery using a spectrometer on TGO and further images taken by the agency's Mars Express orbiter. The frost appears as a bluish hue on the caldera floors and is absent from well-lit slopes. [...] [W]riting in Nature Geoscience, the researchers describe how Martian winds may blow up the mountainsides and carry more moist air into the calderas where it condenses and settles as frost at particular times of year. Modeling of the process suggests the frost is water ice as the peaks are not cold enough for carbon dioxide frost to form.

Insurers Are Spying on Your Home From the Sky (wsj.com) 104

Across the U.S., insurance companies are using aerial images of homes as a tool to ditch properties seen as higher risk [non-paywalled link]. From a report: Nearly every building in the country is being photographed, often without the owner's knowledge. Companies are deploying drones, manned airplanes and high-altitude balloons to take images of properties. No place is shielded: The industry-funded Geospatial Insurance Consortium has an airplane imagery program it says covers 99% of the U.S. population. The array of photos is being sorted by computer models to spy out underwriting no-nos, such as damaged roof shingles, yard debris, overhanging tree branches and undeclared swimming pools or trampolines. The red-flagged images are providing insurers with ammunition for nonrenewal notices nationwide.

UK Regulator Trying To Block Release of Shell North Sea Documents (theguardian.com) 61

The UK's oil and gas regulator is coming under fire from environmental groups for using lawyers to try to prevent the publication of five key documents relating to the environmental impact of Shell's activities in the North Sea. From a report: At a hearing in December, a legal representative for the North Sea Transition Authority (NSTA) is expected to argue against the publication of documents that contain details about the risk of pollution as a result of decommissioning the Brent oilfield, which was operated by Shell for more than 40 years. It says it opposes publication "on a matter of process basis." Shell has applied for an exemption from international rules that require all infrastructure to be removed from the field and the UK government is deciding whether it will allow the oil company to leave the 170-metre-high oil platform legs in place for the three platforms known as Bravo, Charlie and Delta.

A total of 64 concrete storage cells are contained in the leg structures, 42 of which have previously been used for oil storage and separation. Most of the cells are the size of seven Olympic swimming pools, and collectively still contain an estimated 72,000 tonnes of contaminated sediment and 638,000 cubic metres of oily water. Environmental groups believe the documents held by the NSTA would reveal new information about long-term environmental dangers that is relevant to other North Sea oil developments, including Equinor's plans to develop Rosebank, the UK's largest untapped field.

To Build Their AI Tech, Microsoft and Google are Using a Lot of Water (apnews.com) 73

An anonymous Slashdot reader shares this report from the Associated Press: The cost of building an artificial intelligence product like ChatGPT can be hard to measure. But one thing Microsoft-backed OpenAI needed for its technology was plenty of water, pulled from the watershed of the Raccoon and Des Moines rivers in central Iowa to cool a powerful supercomputer as it helped teach its AI systems how to mimic human writing.

As they race to capitalize on a craze for generative AI, leading tech developers including Microsoft, OpenAI and Google have acknowledged that growing demand for their AI tools carries hefty costs, from expensive semiconductors to an increase in water consumption. But they're often secretive about the specifics. Few people in Iowa knew about its status as a birthplace of OpenAI's most advanced large language model, GPT-4, before a top Microsoft executive said in a speech it "was literally made next to cornfields west of Des Moines."

Building a large language model requires analyzing patterns across a huge trove of human-written text. All of that computing takes a lot of electricity and generates a lot of heat. To keep it cool on hot days, data centers need to pump in water — often to a cooling tower outside its warehouse-sized buildings. In its latest environmental report, Microsoft disclosed that its global water consumption spiked 34% from 2021 to 2022 (to nearly 1.7 billion gallons, or more than 2,500 Olympic-sized swimming pools), a sharp increase compared to previous years that outside researchers tie to its AI research. "It's fair to say the majority of the growth is due to AI," including "its heavy investment in generative AI and partnership with OpenAI," said Shaolei Ren, a researcher at the University of California, Riverside who has been trying to calculate the environmental impact of generative AI products such as ChatGPT. In a paper due to be published later this year, Ren's team estimates ChatGPT gulps up 500 milliliters of water (close to what's in a 16-ounce water bottle) every time you ask it a series of between 5 to 50 prompts or questions...

Google reported a 20% growth in water use in the same period, which Ren also largely attributes to its AI work.

OpenAI and Microsoft both said they were working on improving "efficiencies" of their AI model-training.

App That Lets Homeowners Rent Their Swimming Pools Draws Backlash (msn.com) 152

Somewhere in Maryland, an app that lets homeowners rent their swimming pools "has sharply divided suburban residents of Montgomery County as the local government considers formally regulating the short-term amenity rentals," reports the Washington Post, "potentially becoming the first in the nation to do so." Neighbors have spied on neighbors, reporting unwanted outsiders flocking to their quiet residential streets. "Our entire block has been disturbed," Constance Kiggans, a Chevy Chase resident, said in written testimony to the Montgomery County Council. "It is, for all intents and purposes, like having a pool club on the street..." Unlike long-established home rental and ride sharing apps, newer apps that let people rent out their pools, home gyms and backyards have largely been unregulated across the United States so far. In fact, several jurisdictions, from the city of San Jose to towns across New Jersey to the state of Wisconsin, have tried over the past three years to ban the rentals or set up strict rules that require private pools to meet the same standards as a public pool...

Many homeowners are eager to earn easy money by renting out a backyard pool, despite a murky legal landscape that does not offer clear guidance on whether the rentals are legal or not...

Chief among the complaints detailed by pool sharing opponents is the noise... [36 residents who signed a letter of complaint] argued that the rentals turn quiet residential neighborhoods into bustling business districts, without the infrastructure to support commercial activity. They raised dozens of concerns, largely over the added nuisance of strangers pouring into their neighborhoods because of the apps, congested roads, scarce parking, and noise and safety. Their complaints have shut down at least one pool rental in the county.

Free Data-Center Heat Is Allegedly Saving a Struggling Public Pool $24K a Year (arstechnica.com) 34

An anonymous reader quotes a report from Ars Technica: A public pool in the UK is expected to save [about $24,000] and cut carbon emissions by 25.8 tons annually by warming a 25-meter children's pool with waste heat from a data center from startup Deep Green. UK-based Deep Green is a newcomer in the data-center heat game and is making its entrance notable by putting a monetary figure on potential savings, which are fueled by the heat's low, low rate of free. Deep Green's paying customers are machine-learning and AI firms seeking computing resources. As reported by Datacenter Dynamics on Tuesday, clients can leverage Deep Green's 28 kW system with high-performance computing (HPC) capabilities. The HPC cluster at the Exmouth Leisure Centre swimming pool has 12 four-CPU cards and could eventually be used for cloud services and video rendering, Deep Green CEO Mark Bjornsgaard told the publication. According to the BBC , the server is about the size of a washing machine.

The computers are submerged in mineral oil that captures heat that gets transferred into pool water with a heat exchanger. The pool still has a gas boiler to boost the water's temperature if required. Deep Green claims it's transferring about 96 percent of the energy used by its computers and reducing a pool's gas heat usage by 62 percent. Deep Green is paying the Exmouth Leisure Centre for all the electricity its data center uses, as well as any setup costs, and the Exmouth Leisure Centre gets the heat for free.

Deep Green CTO Mat Craggs told Datacenter Dynamics: "Our expected heat transfer from the kit is 139,284 kWh a year, equivalent to 62 percent of the pool's heat needs." He noted that adding more servers to the tub could extend the figure to 70 or 80 percent. Deep Green's data center can heat the Exmouth Leisure Centre's 25 meter pool to 86 degrees Fahrenheit for about 60 percent of the time, BBC reported. The startup has plans to set up data centers in seven more UK locations and has a 2023 target of 20 locations.

Newly Discovered Asteroid Has a '1 In 560 Chance' of Hitting Earth In 2046 67

A newly discovered asteroid roughly the size of an Olympic swimming pool has a "small chance" of colliding with Earth in 23 years, with a potential impact on Valentine's Day in 2046, according to NASA's Planetary Defense Coordination Office. From a report: The asteroid has a 1 in 625 chance of striking Earth, based on data projections from the European Space Agency, though NASA's Jet Propulsion Laboratory's Sentry system calculated the odds closer to 1 in 560. The latter tracks potential collisions with celestial objects. But the space rock -- named 2023 DW -- is the only object on NASA's risk list that ranks 1 out of 10 on the Torino Impact Hazard Scale, a metric for categorizing the projected risk of an object colliding with Earth. All other objects rank at 0 on the Torino scale.

NASA officials have warned that the odds of impact could be dramatically altered as more observations of 2023 DW are collected and additional analysis is performed. It may be a few days before new data can be collected because of the asteroid's proximity to the moon [...]. The last full moon was two days ago, and it still appears bright and large in the sky, likely obscuring 2023 DW from immediate observation.

The asteroid measures about 160 feet (about 50 meters) in diameter, according to NASA data. As 2023 DW orbits the sun, it has 10 predicted close approaches to Earth, with the nearest landing on February 14, 2046, and nine others between 2047 and 2054. The closest the asteroid is expected to travel to Earth is about 1.1 million miles (1.8 million kilometers), NASA's Eyes on Asteroids website notes. The space rock was first spotted in our skies on February 2. It's traveling about 15.5 miles per second (25 kilometers per second) at a distance of more than 11 million miles (18 million kilometers) from Earth, completing one loop around the sun every 271 days.

Scientists Have Created the World's Smallest Organism That Moves With Genetic Engineering (vice.com) 11

An anonymous reader quotes a report from Motherboard: Motility -- the scientific term for being able to move independently -- is one of the most important features for living organisms on Earth. But where cells' ability to move came from has been a mystery for many scientists. However, new research in which scientists created the world's smallest moving organism provides one idea of how cell motility came to be. As the authors write in their paper, "motility is observed in various phyla and arguably one of the major determinants of survival." According to the paper, cell motility is believed to originate from small movements of housekeeping proteins that are transmitted to a cell, but the proposed process hasn't been experimentally demonstrated. Their study is thus a way to test out this theory.

In this experiment, the researchers genetically engineered a synthetic bacterium named JCVI-syn-3b, or syn-3, which is non-motile. To reconstitute syn-3, the group introduced seven genes that code for proteins that are likely involved in the swimming motion of Spiroplasma bacteria. Spiroplasma is a small bacteria known to "swim" by essentially switching around its cytoskeleton. The proteins introduced evolved from the bacterial actin protein MreB. Actin are multi-functional proteins that are often responsible for motility in cells. In an email to Motherboard, Miyata confirmed that prior to this experiment, nobody had succeeded in making a motile minimal synthetic bacterium. By introducing the proteins responsible for motility in Spiroplasma into syn-3, the researchers were able to make the previously non-motile bacteria swim, as evident in a video published on the University's YouTube account.

The researchers also wanted to see how the expression of different combinations of the motility genes would affect the genetically engineered bacteria to swim. In doing so, they found that the expression of only two proteins was necessary for promoting motility in syn-3, likely indicating that many of the proteins were redundant and demonstrating a minimal system for motility. "To the best of our knowledge, the motility system comprising only two actin superfamily proteins is the smallest system established till date," the authors write. "Therefore, we may call this a 'minimal motile cell.'" Although this study is primarily a proof of concept, it gives scientists a better understanding of how cell motility could have potentially originated and evolved.
"In addition to the sheer novelty of creating such a smol swimmer, the new study sheds light on the origin of movement in the first mobile lifeforms that arose on Earth," adds Motherboard. "For instance, Miyata said that the actin protein MreB is not involved in the motility of many other bacterial species, which confirms that there are multiple different evolutionary pathways that led to microbial movement."

The study has been published in the journal Science Advances.

Mauna Loa Volcano In Hawaii Erupts For the First Time In Nearly 40 Years 22

An anonymous reader quotes a report from The New York Times: The world's largest active volcano, Mauna Loa on the Big Island of Hawaii, erupted for the first time in 38 years late Sunday night, following a series of spectacular eruptions of the smaller Kilauea volcano, also on the island, over the last five years. At 11:30 p.m. local time, an eruption began at Mauna Loa's summit, inside Hawaii Volcanoes National Park, according to the U.S. Geological Survey. Lava flowing from the volcano was confined to the summit area, and officials said there was no immediate threat to the public, but they warned that winds could carry volcanic gas, fine ash and thin glass fibers known as Pele's hair downwind.

The Hawaii County Civil Defense Agency raised the volcano alert level to a warning from an advisory. Mitch Roth, the mayor of Hawaii County, which has a population of about 200,000, said in a statement on Facebook early Monday that there were no evacuation orders or threats to the community. Two shelters were opened along the South Kona coast for people who voluntarily left their homes, officials said. The location and direction of lava flow can quickly change, officials said. Residents who are at risk were advised to review their preparedness plans. Officials said they planned to conduct an aerial survey of the eruption and assess any hazards.

Mauna Loa, which encompasses more than half of the Big Island of Hawaii and rises more than 13,600 feet above the Pacific Ocean, has erupted 33 times since 1843, averaging one eruption every five years. A majority of the eruptions occurred before 1950; since then, there have been only two -- a summit eruption in 1975 and an eruption in 1984, when lava flow approached the city of Hilo. That last eruption caused volcanic air pollution across the state and prompted the authorities to close Highway 200 as lava flow destroyed utility poles and power lines. Heat released during the eruption also caused local thunderstorms and snowfall in certain regions.
"While Mauna Loa has been largely dormant for 38 years, Kilauea, in the southeast corner of the Big Island, is considered one of the most active volcanoes in the world," adds the report. "A months long eruption in 2018 produced 320,000 Olympic-sized swimming pools' worth of lava that transformed the landscape around Kilauea and was blamed for the destruction of around 700 homes."
