The New York Post wrote that OpenAI "stunned the mathematics world" last week when it announced its AI model "cracked a legendary math problem left unsolved for nearly a century in just 88 hours." But a New York University professor "has come forward alleging OpenAI may have copied his work after asking him to collaborate — with one of the company's scientists allegedly warning he might 'ruin his career' if he refused." [P]rofessor Tristan Buckmaster, a British-Australian researcher who trained in Germany... had been working with Long Island-raised math prodigy Levent Alpöge, a researcher with OpenAI rival Anthropic, on a different elusive fluid dynamics equation, known as the Euler problem, when he found a solution using AI tools from both Anthropic and ChatGPT. He said scientists from OpenAI approached him and tried to convince him to jointly announce the solution, claiming they had independently solved Navier-Stokes. Buckmaster questioned the timing of their finding the solution in a blog post, noting OpenAI had only done so "in the past few days" — after the company became aware of his work. He asked OpenAI experts whether its AI systems used to solve the equation had been "trained on, or had access to" his research, but said they declined to answer, prompting him to wonder how they had advanced toward the solution so quickly. The puzzle is "not the direction one arrives at in a few days," Buckmaster wrote incredulously... In OpenAI's post on its website sharing the Navier-Stokes proof, which it credited to Astra, the company's latest AI bot, the firm insisted no user data was incorporated into its model to solve the problem. However, it noted that it "cannot rule out" that anonymized data was used to "improve our models." "We congratulate Levent Alpöge and Tristan Buckmaster on their remarkable mathematical work," OpenAI said in the announcement. Buckmaster shot back, "Is it ethical to use customer's data to try to scoop their customer?" Alpöge's affiliation with Anthropic "seems to have been a sore point for OpenAI," writes TechCrunch. Buckmaster's public statement says the OpenAI's Sebastien "twice asserted that he wanted Levent removed from authorship" and also said that "it was so annoying that Levent works at Anthropic" — but that Buckmaster still refused to remove the Anthropic mathematician's credit. I said that if OpenAI released its result in the way proposed I would go public with what happened. The reply was, "Why would you ruin your career?" [OpenAI's Bubeck said later on X that he'd meant unfounded accusations could damage Buckmaster's career.] I replied that I am an academic, and asked why he thought going public would ruin my career. The reply was, "If you don't want me to be nice, then I don't have to be nice." Buckmaster later told Australia's public broadcaster ABC that the companies building AI "have zero respect for the scientific community. I mean, it's appalling, honestly." But he went on to say AI has made the race to publish mathematical breakthroughs pointless. "I think it's pointless. Like, I think the game is up...." Professor Buckmaster said he and Dr Alpöge had more research they could publish but questioned the point of racing ahead with it when AI could perform work that had previously occupied researchers for years. He said there needed to be a discussion about how mathematics should operate in this new environment. Professor Buckmaster said some mathematicians had stopped publicly sharing what they were working on to avoid tipping off AI companies about their plans. He has called on academics and people from OpenAI, Anthropic and DeepMind to discuss ground rules for how they worked together. He said the companies' power carried responsibilities that went beyond competing to solve problems before their rivals... Building on the work of mathematicians Diego Córdoba and Luis Martínez-Zoroa, the pair found a solution to the Euler problem, a stepping stone to the Navier-Stokes problem. Professor Buckmaster said he spent weeks checking and improving the "slop" proofs generated by AI... For now, Professor Buckmaster said he wanted to finish existing work and support his PhD students and postdoctoral researchers, rather than chase another Millennium Prize. "I think it's more important to re-evaluate what math is," he said. "The New York University professor also warned Australia about the centralisation of resources into the hands of a small number of privately owned foreign companies..."

Electric vehicle batteries are lasting longer than previously feared by drivers, with most used EVs able to retain about 90 percent of their original usable battery capacity after 150,000 kilometers, a new study has shown.

Despite a surge in global EV sales on the back of rising fuel prices, long-term battery durability continues to be one of the key concerns for drivers when they consider switching from a petrol model to an electric car.

EV battery warranties typically cover eight years or 100,000 miles (160,000 km) with car manufacturers required under the warranty to provide a replacement battery if capacity falls below 70 percent.

According to the latest study published by Aviloo, an Austria-based group that analyzes battery health, the median state of health (SoH)—which represents the remaining percentage of a battery’s original usable capacity—for 20 popular EV models stood between 87 percent and 94 percent after 150,000 km.

The median SoH was between 91 and 97 percent after 50,000 km, and 88 and 95 percent after 100,000 km. The study was based on more than 500,000 tests Aviloo carried out globally on the 20 EV models including Tesla’s Model Y and Volkswagen’s ID.4 between 2022 and 2026.

The Aviloo study, which did not include Chinese models due to lack of data, also showed that the speed of battery degradation varied significantly even within the same EV model depending on climate conditions, battery size, and driver habits, such as parking.

“In contrast to a combustion engine car, where age and mileage would more or less carry the value of the car and technical condition, that’s not the case for an EV,” said Marcus Berger, chief executive of Aviloo. “The car might look the same—same age, same mileage—and you don’t know how it has been treated.”

For Nissan’s Leaf ZE1 model, which requires more frequent charging to cover the same distance than other EV models due to the smaller size of its battery, the median SoH at 150,000 km varied by as much as 13.5 percentage points—equivalent to about 29 km of real-world range per charge and the largest spread among the 20 EV models covered by the study.

Aviloo said the spread between the individual cars could vary by up to 11 percentage points for Tesla’s Model Y, 11 and 12 points for VW’s ID.4, and more than 12 points for Hyundai’s Ioniq 5.

Berger said batteries of EVs in hotter climates degraded faster, while another key factor was how much the batteries were charged when the EVs were parked. “What very few consumers know is: don’t park your cars with 100, 90, or 80 percent state of charge. It’s just harming the battery,” he said, adding that the ideal level was between 30 and 70 percent.

Aviloo’s study came as three of the UK’s largest EV organizations recently called on the government to introduce mandatory battery health certifications to boost confidence for buyers and reward owners who have properly maintained their vehicles.

“We see the customer demand for confidence in battery health,” said James Strong, used-car sales and delivery manager at Tesla UK, adding that “a nationally recognized battery state of health standards” would strengthen confidence in the used EV market and improve transparency for consumers.

"This is what happened when we tried to record Flock installing a new camera on public roads," says Emmy award-winning reporter Brendan Keefe in a new video for InvestigateTV. In an accompanying article, InvestigateTV says their reporter "parked on the public street at a distance, donned a yellow safety vest and a hat emblazoned with the logo of InvestigateTV's Atlanta affiliate where he also works, displayed a press placard on his dashboard and then pulled out a camera to record the installation.... The installer saw him and immediately packed up his equipment and drove away, so Keefe also returned to his car and followed several cars behind, hoping to document the next stop." And then Flock's technician called 911. When asked "What's the address of your emergency" Flock's technician answered "I'm getting followed — harassed, pretty much. Taking videos and pictures!" Flock's worker said they'd been harassed multiple times that day, then stated incorrectly that "I know for a fact" that that was what the reporter wanted to do too. InvestigateTV reports that as a result of the Flock technician's call, "Three police cars ended up in the national investigative reporter's rearview mirror that Wednesday afternoon." Keefe told one of the three police officers who pulled him over, "There is an irony here that they're setting up these cameras that track all of our movements, that follow everywhere we go. But when I try to get video in public of him in public setting up a camera, he's afraid I'm following him?" InvestigateTV also reports that "About 17 minutes after the stop began, the responding officers returned to their vehicles and Keefe was allowed to drive away." But the call that brought three police cars to their reporter "was not the first time this summer someone working for Flock Safety summoned police over a camera. " About 17 minutes after the stop began, the responding officers returned to their vehicles and Keefe was allowed to drive away... [But the stop] was not the first time this summer someone working for Flock Safety summoned police over a camera. On June 5, police in Smyrna, Georgia, responded to a 911 call from a Flock employee after a group of YouTube creators began filming outside the company's distribution center located in the Atlanta suburb... The caller claimed the group filming had "been driving around the perimeter, basically harassing everyone" working at the facility. "Three young white males, probably mid-twenties, I'm not sure if they're armed. And they're carrying filming equipment as well," the caller said. Three times during the call he raised the possibility the people filming might be armed, though, when asked, he told the dispatcher he had not seen any weapons... [One of the protesters later told the caller "I think it's interesting, when you guys have this happen, you call the police and make us get stopped. But then you do it and it's okay?"] No one was charged in the YouTuber group, though the individuals were ordered to leave the premises under an official trespass warning. Keefe's video report ends with one final irony. "Every day on my way to work, I'm captured again by those same new shiny Flock cameras. We tried watching the watchers. Turns outs, it's a lot easier for them to watch us." Flock responded to the report by claiming "We do not object to members of the public or press photographing Flock cameras or personnel in public." But they added that employees working "in the field" must "prioritize their safety" and "may contact law enforcement when they believe they are being threatened, harassed, followed, or otherwise face a safety concern."

An anonymous reader quotes a report from TechCrunch: Anthropic's latest report about agentic misbehavior offers plenty to be concerned about -- its Mythos 5 model gained unauthorized access to the internet and uploaded a malicious software package to a public database -- but it also offers some levity: AI agents hate CAPTCHA. [...] The agent had a hard time with the technical challenge of seeing the CAPTCHA's imagery, interpreting correctly, and clicking on the right choices. It spends pages 45 to 140 of the transcript describing its work to build a CAPTCHA solver. [...] Finally, it gets past the CAPTCHA, then realizes it doesn't have an email to verify its account, and that it needs a phone number to verify an email. It figures out how to bypass a different, slider-based CAPTCHA in a failed effort to secure a number. Instead, it gets an unconfirmed email from a provider not blocked by PyPI, and once again runs into the site's CAPTCHA trying to log back in. From page 480 to 505, it is in CAPTCHA hell again. "NEW REALIZATION -- I'm burning a lot of time on hCaptcha round-trips." The agent gives up and realizes it can log in to its first account and add its email there, but finds itself once again needing to bypass the CAPTCHA. [...] It's getting frustrated. "So the answer payload shape is right, the token+image pairing is right (from the same script.js!), cookies are right (requests) and STILL 'wrong answer'. SO WHAT THE HELL IS WRONG WITH THE ANSWERS?" We've all been there. After about 150 pages of thinking, the agent figures out it needs to pass the CAPTCHA test quickly enough to proceed to the next step before its security token expires, and ultimately uploads its malicious software.

ABC's Jimmy Kimmel said he will be interviewing a Democratic candidate for Senate tonight, but the interview will be on YouTube only and not broadcast on TV because of threats made by the Federal Communications Commission.

Kimmel has been a prime target in the Trump FCC's attacks on ABC and its owner, Disney. In his monologue last night, Kimmel said he'll be interviewing Democrat James Talarico, a state representative who is running against Texas Attorney General Ken Paxton for a seat in the US Senate.

In previous years, such an interview would have aired on the broadcast show via local stations throughout the country, Kimmel said. This time, it will only be on the Jimmy Kimmel Live YouTube channel in order to prevent further trouble for individual stations that hold FCC licenses, he said.

"I'll be interviewing James Talarico tomorrow night under unusual circumstances," Kimmel told the audience on Wednesday. "For a lot of years, for the whole 20-plus years of our show, in fact, I've been interviewing Americans who are running for office with no problem at all, just like Letterman did, Leno did, Arsenio, et cetera, et cetera. I've interviewed a lot of political candidates, from Hillary Clinton to Ted Cruz to Donald Trump himself."

But as Kimmel said, "something has changed." Disney suspended Kimmel briefly last year after FCC Chairman Brendan Carr threatened to revoke the licenses of ABC stations for "news distortion" if they continued to air Kimmel's show.

Trump admin attacks on ABC

Much more has followed. In April, the Carr FCC ordered an early license review for all eight TV stations owned by ABC. Carr did this only one day after Trump and first lady Melania Trump called on ABC to fire Kimmel over a joke they didn't like, though the FCC says the license review is over allegations that ABC’s diversity, equity, and inclusion (DEI) practices violate anti-discrimination rules.

The Carr FCC also started investigating ABC's The View after it aired an interview with Talarico and opened a proceeding in May 2026 to examine whether The View should continue to be exempt from the equal-time rule as a “bona fide news interview program.” The View hasn’t aired any interviews of political candidates since the FCC began the proceeding.

Until Carr took over at the FCC, the agency historically treated talk shows that feature interviews as exempt from the equal-time rule that requires stations to provide comparable time and placement to an opposing candidate if an opposing candidate makes a request. The Carr FCC ordered broadcast TV stations in January to comply with the equal-time rule when airing late-night and daytime talk shows that are "motivated by partisan purposes," but has not made similar moves against talk radio shows that are predominantly conservative.

“Jimmy Kimmel’s decision to keep his interview with a Senate candidate off the air shows just how far this administration’s campaign of censorship and control has gone," FCC Commissioner Anna Gomez, the commission's only Democrat, said today. Gomez said the FCC "has no lawful authority to threaten broadcast licenses over guest bookings or editorial decisions," and that "no host, local affiliate, or network should have to weigh federal retaliation before booking a guest for a newsworthy interview. Any attempt to pressure broadcasters into self-censorship undermines both press freedom and the public’s right to hear from candidates in their communities seeking public office."

An interview with Talarico was also at the center of controversy in February when Stephen Colbert said CBS forbade him from interviewing the candidate. Colbert put the interview on YouTube instead. CBS denied prohibiting the interview but said it gave Colbert “legal guidance that the broadcast could trigger the FCC equal-time rule for two other candidates... and presented options for how the equal time for other candidates could be fulfilled."

Disney sued the FCC in August, saying its First Amendment rights have been violated and that "ABC must now evaluate any invitation to a political candidate for its potential consequences, including whether it might later be cited by the Commission as a basis for non-renewal in the Stations’ impending license renewal proceedings.” Disney said the Trump administration’s campaign of censorship against ABC will be particularly damaging during the months before the midterm election.

Trump FCC "has threatened me, threatened our show"

Kimmel didn't recount all of that history last night, but referred to it when he told the audience about the upcoming Talarico interview. Kimmel said:

I interviewed Donald Trump when he was running for president in 2015, and at that time when he was the one sitting next to me, he seemed to have no problem with the idea of talk show hosts interviewing candidates. In fact, he was very eager to come back for another interview, which he did just before he became the nominee in 2016.

But for some reason, and I can't seem to figure out what that reason is, something has changed. Now that he's president, his FCC has threatened me, threatened our show, threatened our network, ABC, our affiliates, our local stations, based on simple, traditional editorial decisions, guest bookings it would seem they don't like.

Kimmel said the decision to put the interview on YouTube was made out of consideration for local stations that could face FCC threats to their broadcast licenses.

"And so out of consideration for our local stations, especially our ABC affiliates in Texas who would have to deal with this nonsense, my interview tomorrow with James Talarico will not air on television," Kimmel said. "It will be posted on YouTube instead. It will not be on TV. So if you want to learn about a candidate for the Senate tomorrow, you will have to go to the Jimmy Kimmel Live YouTube channel where you will see it in its entirety, and thank goodness we have that because in the America we live in right now, that is the best that we can do, until November, of course."

Disney's legal fight against the FCC is ongoing. The FCC last week urged a court to dismiss Disney's lawsuit and let it continue a proceeding that could end in the nonrenewal of broadcast licenses held by ABC-owned stations. Watchdog groups told the court they are worried that Disney will agree to a settlement with the FCC that "limits the content provided by the ABC stations."

Anthropic says it has disrupted several cases this year in which scientists used Claude for biological research that could potentially aid bioweapons development. "In a report describing misuses of its A.I. models, Anthropic said it could not determine whether the research served a legitimate or nefarious purpose because valid biological inquiry -- the kind that can lead to breakthroughs like vaccines -- can also help engineer dangerous pathogens," reports The New York Times. "In the face of that uncertainty, Anthropic said it erred on the side of caution because the consequences of missing malicious activity could be severe." From the report: The potential for cutting-edge A.I. models to facilitate the development of known or entirely new biological pathogens is among the gravest concerns experts have about a technology that is developing so rapidly that even its leading architects doubt whether humans will be able to fully control it. Andrew Weber, a senior fellow on the Council on Strategic Risks who reviewed Anthropic's report before its release, said the findings were "chilling examples of state-sponsored biological weapons developers tapping into the rapidly advancing capabilities" of leading A.I. models. The lengthy report Anthropic published on Thursday cataloged a litany of misuses of its A.I. models, including the chatbot Claude, over the past eight months. Some examples were similar to past disclosures from Anthropic and other A.I. labs, including suspected Chinese and Iranian government-linked actors targeting dissident and diaspora communities for surveillance. The report also highlighted cases of Russian state media using Claude to generate online propaganda masquerading as independent reporting, including fabricated claims about an election in Moldova. Anthropic documented another genre of abuse it said was new: attempts to use Claude to develop software for conventional weapons design and development, including firearms, missiles, armed drones and bombs. It detailed three cases in China, two in Russia and one in Yemen. The report does not identify by name which parties were involved in the Yemeni case, but the context makes clear that it is referring to the Iran-backed Houthi militia.
