  • Ubisoft Shows Off New AI-Powered FPS And Hopes You've Forgotten About Its Failed NFTs
    by msmash on 24/11/2025 at 2:40 pm

    Ubisoft has revealed Teammates, a first-person shooter built around AI-powered squadmates that the company is calling its "first playable generative AI research project" -- not long after the publisher went all-in on NFTs and the metaverse only to largely move on from both. Built in the Snowdrop Engine that powers The Division 2 and Star Wars Outlaws, the game features an AI assistant named Jaspar and two AI squadmates called Pablo and Sofia. Players can issue natural voice commands to direct the squadmates in combat or puzzle-solving, while Jaspar handles mission tracking and guidance. The project comes from the same team behind Ubisoft's Neo NPCs, demonstrated at GDC 2024. Read more of this story at Slashdot.

  • How Google Finally Leapfrogged Rivals With New Gemini Rollout
    by msmash on 24/11/2025 at 2:02 pm

    An anonymous reader shares a report: With the release of its third version last week, Google's Gemini large language model surged past ChatGPT and other competitors to become the most capable AI chatbot, as determined by consensus industry-benchmark tests. [...] Aaron Levie, chief executive of the cloud content management company Box, got early access to Gemini 3 several days ahead of the launch. The company ran its own evaluations of the model over the weekend to see how well it could analyze large sets of complex documents. "At first we kind of had to squint and be like, 'OK, did we do something wrong in our eval?' because the jump was so big," he said. "But every time we tested it, it came out double-digit points ahead." [...] Google has been scrambling to get an edge in the AI race since the launch of ChatGPT three years ago, which stoked fears among investors that the company's iconic search engine would lose significant traffic to chatbots. The company struggled for months to get traction. Chief Executive Sundar Pichai and other executives have since worked to overhaul the company's AI development strategy by breaking down internal silos, streamlining leadership and consolidating work on its models, employees say. Sergey Brin, one of Google's co-founders, resumed a day-to-day role at the company helping to oversee its AI-development efforts. Read more of this story at Slashdot.

  • New Mars Orbiter Manuever Challenges Theory: That May Not Be an Underground Lake on Mars
    by EditorDavid on 24/11/2025 at 12:34 pm

    In 2018 researchers claimed evidence of a lake beneath the surface of Mars, detected by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument (or Marsis for short). But new Mars observations "are not consistent with the presence of liquid water in this location and an alternative explanation, such as very smooth basal materials, is needed." Phys.org explains Aboard the Mars Reconnaissance Orbiter, the Shallow Radar (SHARAD) uses higher frequencies than MARSIS. Until recently, though, SHARAD's signals couldn't reach deep enough into Mars to bounce off the base layer of the ice where the potential water lies — meaning its results couldn't be compared with those from MARSIS. However, the Mars Reconnaissance Orbiter team recently tested a new maneuver that rolls the spacecraft on its flight axis by 120 degrees — whereas it previously could roll only up to 28 degrees. The new maneuver, termed a "very large roll," or VLR, can increase SHARAD's signal strength and penetration depth, allowing researchers to examine the base of the ice in the enigmatic high-reflectivity zone. Gareth Morgan and colleagues, for their article published in Geophysical Research Letters, examined 91 SHARAD observations that crossed the high-reflectivity zone. Only when using the VLR maneuver was a SHARAD basal echo detected at the site. In contrast to the MARSIS detection, the SHARAD detection was very weak, meaning it is unlikely that liquid water is present in the high-reflectivity zone. Read more of this story at Slashdot.

  • How An MIT Student Awed Top Economists With His AI Study - Until It All Fell Apart
    by EditorDavid on 24/11/2025 at 9:34 am

    In May MIT announced "no confidence" in a preprint paper on how AI increased scientific discovery, asking arXiv to withdraw it. The paper, authored by 27-year-old grad student Aidan Toner-Rodgers, had claimed an AI-driven materials discovery tool helped 1,018 scientists at a U.S. R&D lab. But within weeks his academic mentors "were asking an unthinkable question," reports the Wall Street Journal. Had Toner-Rodgers made it all up? Toner-Rodgers's illusory success seems in part thanks to the dynamics he has now upset: an academic culture at MIT where high levels of trust, integrity and rigor are all — for better or worse — assumed. He focused on AI, a field where peer-reviewed research is still in its infancy and the hunger for data is insatiable. What has stunned his former colleagues and mentors is the sheer breadth of his apparent deception. He didn't just tweak a few variables. It appears he invented the entire study. In the aftermath, MIT economics professors have been discussing ways to raise standards for graduate students' research papers, including scrutinizing raw data, and students are going out of their way to show their work isn't counterfeit, according to people at the school. Since parting with the university, Toner-Rodgers has told other students that his paper's problems were essentially a mere issue with data rights. According to him, he had indeed burrowed into a trove of data from a large materials-science company, as his paper said he did. But instead of getting formal permission to use the data, he faked a data-use agreement after the company wanted to pull out, he told other students via a WhatsApp message in May... On Jan. 31, Corning filed a complaint with the World Intellectual Property Organization against the registrar of the domain name corningresearch.com. Someone who controlled that domain name could potentially create email addresses or webpages that gave the impression they were affiliated with the company. WIPO soon found that Toner-Rodgers had apparently registered the domain name, according to the organization's written decision on the case. Toner-Rodgers never responded to the complaint, and Corning successfully won the transfer of the domain name. WIPO declined to comment... In the WhatsApp chat in May, in which Toner-Rodgers told other students he had faked the data-use agreement, he wrote, "This was a huge and embarrassing act of dishonesty on my part, and in hindsight it clearly would've been better to just abandon the paper." Both Corning and 3M told the Journal that they didn't roll out the experiment Toner-Rodgers described, and that they didn't share data with him. Read more of this story at Slashdot.

  • 'We Could've Asked ChatGPT': UK Students Fight Back Over Course Taught By AI
    by EditorDavid on 24/11/2025 at 5:35 am

    An anonymous reader shared this report from the Guardian: James and Owen were among 41 students who took a coding module at the University of Staffordshire last year, hoping to change careers through a government-funded apprenticeship programme designed to help them become cybersecurity experts or software engineers. But after a term of AI-generated slides being read, at times, by an AI voiceover, James said he had lost faith in the programme and the people running it, worrying he had "used up two years" of his life on a course that had been done "in the cheapest way possible". "If we handed in stuff that was AI-generated, we would be kicked out of the uni, but we're being taught by an AI," said James during a confrontation with his lecturer recorded as a part of the course in October 2024. James and other students confronted university officials multiple times about the AI materials. But the university appears to still be using AI-generated materials to teach the course. This year, the university uploaded a policy statement to the course website appearing to justify the use of AI, laying out "a framework for academic professionals leveraging AI automation" in scholarly work and teaching... For students, AI teaching appears to be less transformative than it is demoralising. In the US, students post negative online reviews about professors who use AI. In the UK, undergraduates have taken to Reddit to complain about their lecturers copying and pasting feedback from ChatGPT or using AI-generated images in courses. "I feel like a bit of my life was stolen," James told the Guardian (which also quotes an unidentified student saying they felt "robbed of knowledge and enjoyment".) But the article also points out that a survey last year of 3,287 higher-education teaching staff by edtech firm Jisc found that nearly a quarter were using AI tools in their teaching.

  • Napster Said It Raised $3 Billion From a Mystery Investor. But Now the 'Investor' and 'Money' Are Gone
    by EditorDavid on 24/11/2025 at 2:35 am

    An anonymous reader shared this report from Forbes: On November 20, at approximately 4 p.m. Eastern time, Napster held an online meeting for its shareholders; an estimated 700 of roughly 1,500 including employees, former employees and individual investors tuned in. That's when its CEO John Acunto told everyone he believed that the never-identified big investor — who the company had insisted put in $3.36 billion at a $12 billion valuation in January, which would have made it one of the year's biggest fundraises — was not going to come through. In an email sent out shortly after, it told existing investors that some would get a bigger percentage of the company, due to the canceled shares, and went on to describe itself as a "victim of misconduct," adding that it was "assisting law enforcement with their ongoing investigations." As for the promised tender offer, which would have allowed shareholders to cash out, that too was called off. "Since that investor was also behind the potential tender, we also no longer believe that will occur," the company wrote in the email. At this point it seems unlikely that getting bigger stakes in the business will make any of the investors too happy. The company had been stringing its employees and investors along for nearly a year with ever-changing promises of an impending cash infusion and chances to sell their shares in a tender offer that would change everything. In fact, it was the fourth time since 2022 they've been told they could soon cash out via a tender offer, and the fourth time the potential deal fell through. Napster spokesperson Gillian Sheldon said certain statements about the fundraise "were made in good faith based on what we understood at the time. We have since uncovered indications of misconduct that suggest the information provided to us then was not accurate." The article notes America's Department of Justice has launched an investigation (in which Napster is not a target), while the Securities and Exchange Commission has a separate ongoing investigation from 2022 into Napster's scrapped reverse merger. While Napster announced they'd been acquired for $207 million by a tech company named Infinite Reality, Forbes says that company faced "a string of lawsuits from creditors alleging unpaid bills, a federal lawsuit to enforce compliance with an SEC subpoena (now dismissed) and exaggerated claims about the extent of their partnerships with Manchester City Football Club and Google. The company also touted 'top-tier' investors who never directly invested in the firm, and its anonymous $3 billion investment that its spokesperson told Forbes in March was in "an Infinite Reality account and is available to us" and that they were 'actively leveraging' it..." And by the end, "Napster appears to have been scrambling to raise cash to keep the lights on, working with brokers and investment advisors including a few who had previously gotten into trouble with regulators.... If it turns out that Napster knew the fundraise wasn't happening and it benefited from misrepresenting itself to investors or acquirees, it could face much bigger problems. That's because doing so could be considered securities fraud." Read more of this story at Slashdot.
