An anonymous reader quotes a report from Ars Technica: Silicon Valley investors such as Palantir co-founder Peter Thiel have bet hundreds of millions of dollars on deploying AI data centers powered by waves in the middle of the world's oceans -- a move that coincides with tech companies facing mounting challenges in building AI data center projects on land. The latest investment round of $140 million is intended to help the company Panthalassa complete a pilot manufacturing facility near Portland, Oregon, and speed up deployments of wave-riding "nodes" designed to generate electrical power, according to a May 4 press release. Instead of sending renewable energy to a land-based data center, the floating nodes would directly power onboard AI chips and transmit inference tokens representing the AI models' outputs to customers worldwide via satellite link. Each node resembles a huge steel sphere bobbing on the water with a tube-like structure extending vertically down beneath the surface. The wave motions drive water upward through the tube into a pressurized reservoir, where it can be released to spin a turbine generator that produces renewable energy for the AI chips on board. Panthalassa claims the node's AI chips would also get cooled using the surrounding water, which could offer another advantage over traditional data centers. "Ocean-based compute might offer a massive cooling advantage because the ambient temperature is so low," Lee said. "Land-based data centers use a lot of electricity and fresh water for cooling." The newest node prototype, called Ocean-3, is scheduled for testing in the northern Pacific Ocean later in 2026. The latest version reaches about 85 meters in length and would stand nearly as tall as London's Big Ben or New York City's Flatiron Building, according to the Financial Times. Panthalassa has already tested several earlier prototypes of the wave energy converter technology, including the Ocean-1 in 2021 and the Ocean-2 that underwent a three-week sea trial off the coast of Washington state in February 2024. The company's CEO and co-founder, Garth Sheldon-Coulson, said in a CBS interview that he hopes to eventually deploy thousands of the nodes.

Microsoft is winding down Xbox Copilot on mobile and ending development of Copilot on console, reversing plans to bring the gaming-focused AI assistant to current-generation Xbox consoles this year. "The move follows [new Xbox CEO Asha Sharma's] reorganization of the Xbox platform team earlier on Tuesday, which added executives from Microsoft's CoreAI team -- where Sharma worked before taking over Xbox -- to the Xbox side of the company," reports The Verge. Sharma said in a post on X: Xbox needs to move faster, deepen our connection with the community, and address friction for both players and developers. Today, we promoted leaders who helped build Xbox, while also bringing in new voices to help push us forward. This balance is important as we get the business back on track. As part of this shift, you'll see us begin to retire features that don't align with where we're headed. We will begin winding down Copilot on mobile and will stop development of Copilot on console. Since taking over for former Microsoft Gaming CEO Phil Spencer in February, Sharma has scrapped the Microsoft Gaming brand and cut the price of Xbox Game Pass.

New submitter spazmonkey writes: From a hidden GPS tracker polling your location every 4.5 minutes to JavaScript loaded from a random GitHub account, no SSL certificate pinning, and an in-app browser that silently strips cookie consent dialogs and paywalls from every page you visit, the new White House app seems to have a little bit of everything. A security researcher pulled the APK apart to discover the cybersecurity vulnerabilities. "The app is a React Native build using Expo SDK 54, with WordPress powering the backend through a custom REST API," reports Android Headlines. "That's pretty normal, as nearly 42% of all websites on the internet are powered by WordPress. But that's just the start; now the nightmare begins..." From the report: To start, the app has a full GPS tracking pipeline compiled in. Essentially, it's set to poll your location every 4.5 minutes in the foreground, and 9.5 minutes in the background. It's syncing latitude, longitude, accuracy, and timestamp data to OneSignal's servers. These location permissions aren't declared in the AndroidManifest, but they are hardcoded as runtime requests in the OneSignal SDK. Some have noted that the tracking only kicks in if the developer enables it server-side and the user grants permission, but it is there, ready to go. And it gets even stranger. Apparently, the app is loading JavaScript from a random person's GitHub site for YouTube embeds. Yes, you read that right, it's just loading JavaScript from a random GitHub site. So if that account ever gets compromised, arbitrary code could run inside the app's WebView. There's also no SSL certificate pinning, meaning that traffic can potentially be intercepted on compromised networks like sketchy public WiFi or corporate proxies. The app also injects JavaScript and CSS into every page you visit in the in-app browser. This strips away cookie consent dialogs, GDPR banners, login walls, and paywalls. There's also leftover dev artifacts in the production build, including a localhost URL to the Metro bundler.

Atmospheric carbon dioxide hit a new record in April, averaging about 431 parts per million at NOAA's Mauna Loa Observatory. That's up from under 320 ppm when the site began measurements in 1958. Scientific American reports: Greenhouse gases, such as carbon dioxide, are measured as a proportion of the total atmosphere. The numbers are presented as the number of molecules of a particular gas out of a million total molecules, or ppm. Climate scientist Zachary Labe of Climate Central, a nonprofit that researches climate change, says the new record is "depressing" but not unexpected. "It's just another sign that carbon dioxide continues to increase in our atmosphere as our planet continues to warm," he says. "For many climate scientists, this is just 'here it is again, another record in the wrong direction.'" Labe explains that the amount of CO2 in the atmosphere tends to peak in April each year as decaying plants release greenhouse gases after winter. Some of that CO2 gets reabsorbed by plants as they grow during the warmer months. But NOAA's data show a worrying trend, with the average monthly amount of CO2 steadily increasing. [...] Although the amount of CO2 in the atmosphere has continued to rise, there was a reduction in U.S. emissions in 2023 and 2024. That trend, however, was reversed in 2025, at least partially because of the increased electricity demand from artificial intelligence data centers. Still, Labe says there are reasons for optimism as the use of renewable energy sources such as solar and wind expands.

An anonymous reader quotes a report from CNBC: OpenAI President Greg Brockman concluded his testimony on Tuesday, where he largely rebutted Elon Musk's account of the early years of the startup and negotiations that occurred at the company. Brockman testified that he never made any commitments to Musk about the company's corporate structure, and he never heard anyone else make them. He emphasized that OpenAI is still governed by a nonprofit. "This entity remains a nonprofit," Brockman said, referring to the OpenAI foundation. "It is the best-resourced nonprofit in the world." [...] Brockman, who spoke from the witness stand in federal court in Oakland, California, over the course of two days, also revealed that Musk had enlisted several OpenAI employees to do months of free work for him at Tesla, Musk's electric vehicle company. That work mainly included efforts to overhaul the company's approach to developing self-driving technology as part of the Autopilot team there in 2017. During his two days on the stand, Brockman answered questions about his personal financial ambitions, his understanding of OpenAI's structure and Musk's involvement at the company, which they co-founded with other executives in 2015. In Musk's testimony last week, the Tesla and SpaceX CEO said that the time, money and resources he poured into OpenAI had been integral to the company's success. He repeatedly said that he helped recruit the company's top talent. Brockman said Tuesday that while Musk was helpful in convincing some employees to take the leap to join OpenAI, he was a polarizing figure for others. "Elon had a reputation of being an extremely hard driver," Brockman said. He added that "certain candidates were very attracted" by Musk's involvement at OpenAI, and that "certain candidates were very turned off." Musk testified last week that a former OpenAI researcher named Andrej Karpathy joined Tesla, but only after he had planned to leave the startup already. Brockman said that Musk, after he hired Karpathy, approached him with "an apology and a confession," about the hire, and that neither Musk nor Karpathy had told him the researcher planned to leave OpenAI before that. Musk was generally not very available for meetings and conversations, Brockman said, so he relied on employees, including Sam Teller and former OpenAI board member Shivon Zilis, as proxies. Brockman testified that open sourcing OpenAI's technology was "not a topic of conversation" during Musk's time with the nonprofit, despite Musk's claims that it was supposed to be central to the organization. He also described tense 2017 negotiations over a possible for-profit arm, saying Musk became angry when equity stakes were discussed. "He said Musk declined the proposal during an in-person meeting, then tore a painting of a Tesla Model 3 car off the wall, and began storming out of the room," reports CNBC. He also demanded to know when the cofounders would leave the company. Brockman further said Musk wanted control of OpenAI because he disliked situations where he lacked control, citing Zip2 and SolarCity as examples Musk had raised. He also testified that Musk partly wanted control to help fund his broader SpaceX ambition of building a "city on Mars." CNBC notes the trial will resume at 8:30 a.m. PT on Wednesday, with Shivon Zilis expected to testify. She is the mother of four of Musk's children and a former OpenAI board member.
