Nintendo's Satellaview, a Japan-only satellite add-on for the Super Famicom, is a rich target for preservationists because it was the home to some of the most ephemeral games ever released.

That includes a host of content for Nintendo's own games, including F-Zero. That influential Super Nintendo (Super Famicom in Japan) racing title was the subject of eight weekly broadcasts sent to subscribing Japanese homes in 1996 and 1997, some with live "Soundlink" CD-quality music and voiceovers. When live game broadcasts were finished, the memory cartridges used to store game data would report themselves as empty, even though they technically were not. Keeping that same 1MB memory cartridge in the system when another broadcast started would overwrite that data, and there were no rebroadcasts.

As reported by Matthew Green at Press the Buttons (along with Did You Know Gaming's informative video), data from some untouched memory cartridges was found and used to re-create some of the content. Some courses, part of a multi-week "Grand Prix 2" event, have never been found, despite a $5,000 bounty offering and extensive effort. And yet, remarkably, the 10 courses in those later broadcasts were reverse-engineered, using a VHS recording, machine learning tools, and some manual pixel-by-pixel re-creation. The results are "north of 99.9% accurate," according to those who crafted it and exist now as a mod you can patch onto an existing F-Zero ROM.

Voyager 1 is still alive out there, barreling into the cosmos more than 15 billion miles away. However, a computer problem has kept the mission's loyal support team in Southern California from knowing much more about the status of one of NASA's longest-lived spacecraft.

The computer glitch cropped up on November 14, and it affected Voyager 1's ability to send back telemetry data, such as measurements from the spacecraft's science instruments or basic engineering information about how the probe was doing. So, there's no insight into key parameters regarding the craft's propulsion, power, or control systems.

"It would be the biggest miracle if we get it back. We certainly haven't given up," said Suzanne Dodd, Voyager project manager at NASA's Jet Propulsion Laboratory, in an interview with Ars. "There are other things we can try. But this is, by far, the most serious since I’ve been project manager."

After explicit, fake AI images of Taylor Swift began spreading on X, the platform formerly known as Twitter has attempted to block all searches for the pop star.

"This is a temporary action and done with an abundance of caution as we prioritize safety on this issue," Joe Benarroch, X's head of business operations, said in a statement to Reuters.

However, even this drastic step does not seem to be an effective solution, as "Swift" was trending Monday morning on X. The temporary block also does nothing to stop searches using misspellings of the singer's name.

A small fleet of rideshare Fiat 500e electric vehicles will become testbeds for battery-swap technology in 2024. The experiment is being conducted by Ample, a startup working on battery swaps, and Stellantis, Fiat's parent company, the Verge reported today.

This isn't Ample's first test of its battery-swapping technology; in 2021 it started a small trial in the Bay Area to demo its modular battery, which replaces the existing traction battery in an EV and allows Ample's automated swap stations to switch out depleted packs for charged ones. But the fact that this deal was made with an OEM like Stellantis is still significant.

As we detailed last time we looked at Ample's technology, the EVs require some engineering work for this to all be possible. Ample has to design a structural frame to replace the existing battery pack that will instead contain the swappable modules, while still conforming to the engineering requirements of the original pack—down to the same fasteners, bolts, and connectors.

SpaceX and NASA could take a tentative step toward orbital refueling on the next test flight of Starship, but the US space agency says officials haven't made a final decision on when to begin demonstrating cryogenic propellant transfer capabilities that are necessary to return astronauts to the Moon.

NASA is keen on demonstrating orbital refueling technology, an advancement that could lead to propellant depots in space to feed rockets heading to distant destinations beyond Earth orbit. In 2020, NASA announced agreements with four companies—Lockheed Martin, United Launch Alliance, SpaceX, and a Florida-based startup named Eta Space—to prove capabilities in the area of refueling and propellant depots using cryogenic propellants.

These cryogenic fluids—liquid hydrogen, methane, and liquid oxygen—must be kept at temperatures of several hundred degrees below zero, or they turn into a gas and boil off. Russian supply freighters regularly refuel the International Space Station with hydrazine and nitrogen tetroxide, room-temperature rocket propellants that can be stored for years in orbit, but rockets using more efficient super-cold propellants have typically needed to complete their missions within hours.

The Centers for Disease Control and Prevention is warning everyone in the country to back away from pre-cut cantaloupe unless you're certain the fruit in question is not tied to a large, nationwide Salmonella outbreak that is unusually severe.

So far, 117 cases of infection across 34 states have been identified in the outbreak. The cases are in people ranging from infants to the elderly, including a 100-year-old. Of the cases, 61 (52 percent) have been hospitalized, and two deaths have been reported in Minnesota.

The CDC attributes the unusually high hospitalization rate to the fact that the pre-cut fruit was served at long-term care facilities and childcare centers. The elderly and young children are at higher risk of severe Salmonella illness.

After two days of roller-coaster negotiations at OpenAI HQ due to the surprise ouster of CEO Sam Altman, Microsoft CEO Satya Nadella has announced that Microsoft plans to hire Altman and former OpenAI President Greg Brockman to head a "new advanced AI research team." Overnight, the OpenAI board named a new interim CEO, Emmett Shear, who acknowledged the messy process and promised to hire an investigator to generate a full report on Altman's firing.

But the story isn't over yet, because Monday morning, 650 of 770 OpenAI employees sent a letter to the OpenAI board demanding that all current board members resign and Altman and Brockman be reinstated, or they will likely leave to join Altman and Brockman at Microsoft. (Apparently the number of signatories to the letter is still growing; see update below.)

"The process through which you terminated Sam Altman and removed Greg Brockman from the board has jeopardized all of this work and undermined our mission and company," the letter states. "Your conduct has made it clear you did not have the competence to oversee OpenAI."

On Friday, OpenAI fired CEO Sam Altman in a surprise move that led to the resignation of President Greg Brockman and three senior scientists. The move also blindsided key investor and minority owner Microsoft, reportedly making CEO Satya Nadella furious. As Friday night wore on, reports emerged that the ousting was likely orchestrated by Chief Scientist Ilya Sutskever over concerns about the safety and speed of OpenAI's tech deployment.

"This was the board doing its duty to the mission of the nonprofit, which is to make sure that OpenAI builds AGI that benefits all of humanity," Sutskever told employees at an emergency all-hands meeting on Friday afternoon, as reported by The Information.

Since its founding, OpenAI has pursued the development of artificial general intelligence (or AGI), which is a hypothetical technology that would be able to perform any intellectual task a human can do, potentially replacing a large number of humans at their jobs.

On Monday at the OpenAI DevDay event, company CEO Sam Altman announced a major update to its GPT-4 language model called GPT-4 Turbo, which can process a much larger amount of text than GPT-4 and features a knowledge cutoff of April 2023. He also introduced APIs for DALL-E 3, GPT-4 Vision, and text-to-speech—and launched an "Assistants API" that makes it easier for developers to build assistive AI apps.

OpenAI hosted its first-ever developer event on November 6 in San Francisco called DevDay. During the opening keynote delivered by Altman in front of a small audience, the CEO showcased the wider impacts of its AI technology in the world, including helping people with tech accessibility. Altman shared some stats, saying that over 2 million developers are building apps using its APIs, over 92 percent of Fortune 500 companies are building on their platform, and that ChatGPT has over 100 million active weekly users.

At one point, Microsoft CEO Satya Nadella made a surprise appearance on the stage, talking with Altman about the deepening partnership between Microsoft and OpenAI and sharing some general thoughts about the future of the technology, which he thinks will empower people.

On Monday, Microsoft CEO Satya Nadella showed up at the Google antitrust trial to back the Department of Justice's argument that "Google used unfair tactics"—most significantly, default search contracts—to block opportunities for search competitors like Bing, The Wall Street Journal reported.

A Microsoft spokesperson provided Ars with a transcript of Nadella's morning testimony. It excludes approximately an hour's worth of testimony from the afternoon session (that transcript is not yet available). But it includes about an hour of questioning from DOJ lawyer Adam Severt, during which Nadella said that due to Google's grip on mobile providers and browsers' default search placements, the idea that users have real choices when selecting a search engine is "bogus."

However, Nadella's efforts to back the DOJ seemingly required that the CEO walk back some of his earliest remarks hyping AI-powered Bing as potentially giving Microsoft a long-sought-after competitive advantage over Google.
