ESA finally has a commercial launch strategy, but will member states pay?
The European Space Agency is inviting proposals to inject competition into the European launch market, an important step toward fostering a dynamic multiplayer industry officials hope, one day, will mimic that of the United States.
The near-term plan for the European Launcher Challenge is for ESA to select companies for service contracts to transport ESA and other European government payloads to orbit from 2026 through 2030. A second component of the challenge is for companies to perform at least one demonstration of an upgraded launch vehicle by 2028. The competition is open to any European company working in the launch business.
"What we expect is that these companies will make a step in improving and upgrading their capacity with respect to what they’re presently working," said Toni Tolker-Nielsen, ESA's acting director of space transportation."In terms of economics and physics, it’s better to have a bigger launcher than a smaller launcher in terms of price per kilogram to orbit."

RFK Jr. claws back $11.4B in CDC funding amid wave of top-level departures
More heavy blows are landing at the Centers for Disease Control and Prevention, according to reports Tuesday that reveal a wave of high-level departures from the country's beleaguered health agency. The agency is also losing $11.4 billion in funding for responses to the COVID-19 pandemic, which was largely doled out to chronically underfunded state health departments.
This afternoon, the Associated Press reported that five high-level leaders are departing the agency, which was announced today during a senior staff meeting. The departures, which were described as retirements, follow three other high-level departures in recent weeks. Given that the CDC has two dozen centers and offices, the recent departures reflect a loss of about a third of the agency's top management.
The departures announced today include: Leslie Ann Dauphin, who oversees the Public Health Infrastructure Center, "which serves as the connection point between the agency and state, local, and territorial jurisdictions, tribes. and CDC's public health partners," according to the CDC. Karen Remley, who heads the National Center on Birth Defects and Developmental Disabilities, is also departing, as is Sam Posner, who heads the Office of Science, which provides scientific expertise across the agency and publishes the agency's Morbidity and Mortality Weekly Report. Debra Lubar, who is the CDC's Chief Operating Officer and runs the Office of Policy, Performance and Evaluation, and Leandris Liburd, head of the Office of Health Equity, are also leaving.
Open Source devs say AI crawlers dominate traffic, forcing blocks on entire countries
Software developer Xe Iaso reached a breaking point earlier this year when aggressive AI crawler traffic from Amazon overwhelmed their Git repository service, repeatedly causing instability and downtime. Despite configuring standard defensive measures—adjusting robots.txt, blocking known crawler user-agents, and filtering suspicious traffic—Iaso found that AI crawlers continued evading all attempts to stop them, spoofing user-agents and cycling through residential IP addresses as proxies.
Desperate for a solution, Iaso eventually resorted to moving their server behind a VPN and creating "Anubis," a custom-built proof-of-work challenge system that forces web browsers to solve computational puzzles before accessing the site. "It's futile to block AI crawler bots because they lie, change their user agent, use residential IP addresses as proxies, and more," Iaso wrote in a blog post titled "a desperate cry for help." "I don't want to have to close off my Gitea server to the public, but I will if I have to."
Iaso's story highlights a broader crisis rapidly spreading across the open source community, as what appear to be aggressive AI crawlers increasingly overload community-maintained infrastructure, causing what amounts to persistent distributed denial-of-service (DDoS) attacks on vital public resources. According to a comprehensive recent report from LibreNews, some open source projects now see as much as 97 percent of their traffic originating from AI companies' bots, dramatically increasing bandwidth costs, service instability, and burdening already stretched-thin maintainers.
Praise Kier for Severance season 2! Let’s discuss.
Severance has just wrapped up its second season. I sat down with fellow Ars staffers Aaron Zimmerman and Lee Hutchinson to talk through what we had just seen, covering everything from those goats to the show's pacing. Warning: Huge spoilers for seasons 1 and 2 follow!
Nate: Severance season 1 was a smaller-scale, almost claustrophobic show about a crazy office, its "waffle parties," and the personal life of Mark Scout, mourning his dead wife and "severing" his consciousness to avoid that pain. It followed a compact group of characters, centered around the four "refiners" who worked on Lumon's severed floor. But season 2 blew up that cozy/creepy world and started following more characters—including far more "outies"—to far more places. Did the show manage to maintain its unique vibe while making significant changes to pacing, character count, and location?
Lee: I think so, but as you say, things were different this time around. One element that I’m glad carried through was the show’s consistent use of a very specific visual language. (I am an absolute sucker for visual storytelling. My favorite Kubrick film is Barry Lyndon. I’ll forgive a lot of plot holes if they’re beautifully shot.) Season 2, especially in the back half, treats us to an absolute smorgasbord of incredible visuals—bifurcated shots symbolizing severance and duality, stark whites and long hallways, and my personal favorite: Chris Walken in a black turtleneck seated in front of a fireplace, like Satan holding court in Hell. The storytelling might be a bit less focused, but it looks great.
No cloud needed: Nvidia creates gaming-centric AI chatbot that runs on your GPU
Nvidia has seen its fortunes soar in recent years as its AI-accelerating GPUs have become worth their weight in gold. Most people use their Nvidia GPUs for games, but why not both? Nvidia has a new AI you can run at the same time, having just released its experimental G-Assist AI. It runs locally on your GPU to help you optimize your PC and get the most out of your games. It can do some neat things, but Nvidia isn't kidding when it says this tool is experimental.
G-Assist is available in the Nvidia desktop app, and it consists of a floating overlay window. After invoking the overlay, you can either type or speak to G-Assist to check system stats or make tweaks to your settings. You can ask basic questions like, "How does DLSS Frame Generation work?" but it also has control over some system-level settings.
By calling up G-Assist, you can get a rundown of how your system is running, including custom data charts created on the fly by G-Assist. You can also ask the AI to tweak your machine, for example, optimizing the settings for a particular game or toggling on or off a setting. G-Assist can even overclock your GPU if you so choose, complete with a graph of expected performance gains.
Napster to become a music-marketing metaverse firm after $207M acquisition
Infinite Reality, a media, ecommerce, and marketing company focused on 3D and AI-powered experiences, has entered an agreement to acquired Napster. That means that the brand originally launched in 1999 as a peer-to-peer (P2P) music file-sharing service is set to be reborn again. This time, new owners are reshaping the brand into one focused on marketing musicians in the metaverse.
Infinite announced today a definitive agreement to buy Napster for $207 million. The Norwalk, Connecticut-based company plans to turn Napster into a “social music platform that prioritizes active fan engagement over passive listening, allowing artists to connect with, own, and monetize the relationship with their fans." Jon Vlassopulos, who became Napster CEO in 2022, will continue with his role at the brand.
Since 2016, Napster has been operating as a (legal) streaming service. It claims to have over 110 million high-fidelity tracks, with some supporting lossless audio. Napster subscribers can also listen offline and watch music videos. The service currently starts at $11 per month.

We’ve outsourced our confirmation biases to search engines
People are often quite selective about the information they'll accept, seeking out sources that will confirm their biases, while discounting those that will challenge their beliefs. In theory, search engines can potentially change that. By prioritizing results from high-quality, credible sources, a search engine could ensure that people found accurate information more frequently, potentially opening them to the possibility of updating their beliefs.
Obviously, that hasn't worked out on the technology side, as people quickly learned how to game the algorithms used by search engines, meaning that the webpages that get returned have been created by people with no interest in quality or credibility. But a new study is suggesting that the concept fails on the human side, too, as people tend to devise search terms that are specific enough to ensure that the results of the search will end up reinforcing their existing beliefs.
The study showed that invisibly swapping search terms to something more general can go a long way toward enabling people to change their mind.

FBI probes arson of Tesla cars and facilities, says “this is domestic terrorism”
The Federal Bureau of Investigation yesterday launched a task force "to try to nail the criminals setting fire to Tesla vehicles and charging stations," and is looking into an anarchist blog that has been "calling for more" attacks, The New York Post reported.
"The bureau has received reports of 48 instances so far this month related to Tesla vehicles, dealerships and charging stations and is investigating at least seven of them in conjunction with local law enforcement, The Post has learned," the article said. "The agency's newly formed 10-person task force will deploy ATF personnel—special agents and intelligence analysts from the Bureau of Alcohol, Tobacco, Firearms and Explosives in the Treasury Department—and personnel from the FBI's Counterterrorism Division, including its Domestic Terrorism Operations Section and Weapons of Mass Destruction."
ATF is embedding personnel in some FBI field offices, starting in San Antonio, Texas, "where some of the Molotov cocktail attacks have been carried out," the report said. There were previously three arrests. The FBI is reviewing security camera footage and gained access to cell phone location data in an attempt to find more culprits, the report said.
Momentum seems to be building for Jared Isaacman to become NASA administrator
With the vast majority of President Donald Trump's cabinet members now approved by the US Senate, focus is turning to senior positions within the administration that are just below the cabinet level.
The administrator of NASA is among the most high-profile of these positions. Nearly four months ago Trump nominated private astronaut Jared Isaacman to become chief of the space agency, but he has yet to receive a hearing before the Senate Committee on Commerce, Science, and Transportation.
Almost immediately after his nomination, much of the space community fell in behind Isaacman, who has flown to space twice on private Crew Dragon missions, raised charitable funds, and is generally well-liked. Since then, Isaacman has worked to build support for his candidacy through conversations with people in the space community and officeholders.

Apple barred from Google antitrust trial, putting $20 billion search deal on the line
Apple has suffered a blow in its efforts to salvage its lucrative search placement deal with Google. A new ruling from the DC Circuit Court of Appeals affirms that Apple cannot participate in Google's upcoming antitrust hearing, which could leave a multibillion-dollar hole in Apple's balance sheet. The judges in the case say Apple simply waited too long to get involved.
Just a few years ago, a high-stakes court case involving Apple and Google would have found the companies on opposing sides, but not today. Apple's and Google's interests are strongly aligned here, to the tune of $20 billion. Google forks over that cash every year, and it's happy to do so to secure placement as the default search provider in the Safari desktop and mobile browser.
The antitrust penalties pending against Google would make that deal impermissible. Throughout the case, the government made the value of defaults clear—most people never change them. That effectively delivers Google a captive audience on Apple devices.
