Growing support for far-right parties is pressuring European governments to introduce stricter controls on immigration. Switzerland is set to vote on a proposal that would take the idea to the next level — imposing a cap on its population [non-paywalled link]. The initiative could lead eventually to a blanket ban on new arrivals if the number of residents rises from around 9 million currently to above 10 million, with little distinction made between refugees, skilled workers and top managers on six-figure salaries.

Citizens will likely vote on the proposal next year under the country’s unique system of plebiscites on constitutional amendments and policy, and polls suggest there’s a chance they’ll approve it. The risk is it could lead to shortages of critical skills that end up harming Switzerland’s competitiveness. The outcome will show how far citizens are willing to go to preserve some of the traits that made their country such an appealing destination. […] The right-wing Swiss People’s Party, or SVP, won 28% of the vote in the last election with a campaign that presented Swiss citizenship as a privilege, not a right. It came up with the idea of a population limit in 2023, presenting it as a way to preserve the Swiss lifestyle and protect its environment from excessive human activity.

The new condition would affect people from dozens of countries who are eligible to visit the US for 90 days without a visa, as long as they have filled out an Electronic System for Travel Authorization (ESTA) form. Since returning to the White House in January, President Donald Trump has moved to toughen US borders more generally - citing national security as a reason.

Analysts say the new plan could pose an obstacle to potential visitors, or harm their digital rights. Asked whether the proposal could lead to a steep drop-off in tourism to the US, Trump said he was not concerned. “No. We’re doing so well,” the president said on Wednesday. “We just want people to come over here, and safe. We want safety. We want security. We want to make sure we’re not letting the wrong people come enter our country.”

OpenAI says the cyber capabilities of its frontier AI models are accelerating and warns Wednesday that upcoming models are likely to pose a “high” risk, according to a report shared first with Axios. The models’ growing capabilities could significantly expand the number of people able to carry out cyberattacks. OpenAI said it has already seen a significant increase in capabilities in recent releases, particularly as models are able to operate longer autonomously, paving the way for brute force attacks.

The company notes that GPT-5 scored a 27% on a capture-the-flag exercise in August, GPT-5.1-Codex-Max was able to score 76% last month. “We expect that upcoming AI models will continue on this trajectory,” the company says in the report. “In preparation, we are planning and evaluating as though each new model could reach ‘high’ levels of cybersecurity capability as measured by our Preparedness Framework.” “High” is the second-highest level, below the “critical” level at which models are unsafe to be released publicly.

perm from a donor who unknowingly carried a cancer-causing gene has been used to conceive nearly 200 babies across Europe, an investigation by 14 European public service broadcasters, including CBS News’ partner network BBC News, has revealed. Some children conceived using the sperm have already died from cancer, and the vast majority of those who inherited the gene will develop cancer in their lifetimes, geneticists said. The man carrying the gene passed screening checks before he became a donor at the European Sperm Bank when he was a student in 2005. His sperm has been used by women trying to conceive for 17 years across multiple countries.

The cancer-causing mutation occurred in the donor’s TP53 gene — which prevents cells in the body from turning cancerous — before his birth, according to the investigation. It causes Li Fraumeni syndrome, which gives affected people a 90% chance of developing cancers, particularly during childhood, as well as breast cancer in later life. Up to 20% of the donor’s sperm contained the mutated TP53 gene. Any children conceived with affected sperm will have the dangerous mutation in every cell of their body. The affected donor sperm was discovered when doctors seeing children with cancers linked to sperm donation raised concerns at this year’s European Society of Human Genetics.

At the time, 23 children with the genetic mutation had been discovered, out of 67 children linked to the donor. Ten of those children with the mutation had already been diagnosed with cancer. Freedom of Information requests submitted by journalists across multiple countries revealed at least 197 children were affected, though it is not known how many inherited the genetic mutation. More affected children could be discovered as more data becomes available.

MAVEN launched in November 2013 and entered orbit around Mars in September 2014. The spacecraft’s primary science mission is to study the planet’s upper atmosphere and interactions with the solar wind, including how the atmosphere escapes into space. That is intended to help scientists understand how the planet changes from early in its history, when it had a much thicker atmosphere and was warm enough to support liquid water on its surface.

MAVEN additionally serves as a communications relay, using a UHF antenna to link the Curiosity and Perseverance rovers on the Martian surface with the Deep Space Network. NASA’s Mars Odyssey and Mars Reconnaissance Orbiter spacecraft also serve as communications relays for the rovers, but are both significantly older than MAVEN. The spacecraft has suffered some technical problems in the past, notably with its inertial measurement units (IMUs) used for navigation. In 2022, MAVEN switched to an “all-stellar” navigation system to minimize the use of the IMUs.

MAVEN has enough propellant to maintain its orbit through at least the end of the decade. NASA’s fiscal year 2026 budget proposal, though, zeroed out funding for MAVEN, which cost $22.6 million to operate in 2024. MAVEN was one of several missions “operating well past the end of prime mission” the proposal would terminate, despite MAVEN’s role as a communications relay.

Apple on Wednesday released its annual list of the most downloaded apps and games for the year. For the U.S. market, OpenAI’s ChatGPT topped the ranks of free iPhone apps (not including games) with the most installs in 2025. The AI app was followed by Threads, Google, TikTok, WhatsApp, Instagram, YouTube, Google Maps, Gmail, and Google’s Gemini. ChatGPT made it to No. 4 last year, but the top spot was taken by Chinese shopping app Temu. In 2023, the AI app didn’t make the top-10 list despite being released on the iPhone in May 2023 to a strong debut.

If successful, two leaders of the group tell Ars, Operation Bluebird would launch a social network under the name Twitter.new, possibly as early as late next year. (Twitter.new has created a working prototype and is already inviting users to reserve handles.)

Michael Peroff, an Illinois attorney and founder of Operation Bluebird, said that in the intervening years, more Twitter-like social media networks have sprung up or gained traction — like Threads, Mastodon, and Bluesky. But none have the scale or brand recognition that Twitter did prior to Musk’s takeover. “There certainly are alternatives,” Peroff said. “I don’t know that any of them at this point in time are at the scale that would make a difference in the national conversation, whereas a new Twitter really could.”

Similarly, Peroff’s business partner, Stephen Coates, an attorney who formerly served as Twitter’s general counsel, said that Operation Bluebird aims to recreate some of the magic that Twitter once had. “I remember some time ago, I’ve had celebrities react to my content on Twitter during the Super Bowl or events,” he told Ars. “And we want that experience to come back, that whole town square, where we are all meshed in there.”

Google Play has been in the European Commission’s crosshairs since March, with regulators singling out technical restrictions preventing app developers from steering users to other channels for cheaper offers. Another issue is the service fee charged by Google for facilitating an app developer’s initial acquisition of a new customer via Google Play which the regulator said goes beyond what is justified.

Tweaks to Google Play announced in August to make it easier for app developers to direct customers to other channels and choose a fee model are still falling short, the people said, with the EU antitrust regulator viewing Apple’s recent changes to its App Store as a benchmark. […] Google can still offer to make more changes before regulators impose a fine, likely in the first quarter of the next year, the people said, adding that the timing of any sanction can still change.
