One of the new Trump administration's first national security directives aims to defend against missile and drone attacks targeting the United States, and several elements of the plan require an expansion of the US military's presence in space, the White House announced Monday.

For more than 60 years, the military has launched reconnaissance, communications, and missile warning satellites into orbit. Trump's executive order calls for the Pentagon to come up with a design architecture, requirements, and an implementation plan for the next-generation missile defense shield within 60 days.

A key tenet of Trump's order is to develop and deploy space-based interceptors capable of destroying enemy missiles during their initial boost phase shortly after launch.

For reasons that were not immediately clear, SpaceX founder Elon Musk took to his social media site X on Tuesday evening to make a perplexing space-based pronouncement.

"The @POTUS has asked @SpaceX to bring home the 2 astronauts stranded on the @Space_Station as soon as possible. We will do so," Musk wrote. "Terrible that the Biden administration left them there so long."

Now generally, at Ars Technica, it is not our policy to write stories strictly based on things Elon Musk says on X. However, this statement was so declarative, and so consternation-inducing for NASA, it bears a bit of explication.

BMW wertet nach vier Jahren das Oberklasse-SUV iX auf. Der Preis beim Topmodell sinkt um fast 20.000 Euro, das Basismodell wird teurer. Ein Bericht von Friedhelm Greis (Elektroauto, Wissenschaft)

Atari has partnered with watch maker Nubeo to release a limited edition Asteroids Watch that puts imagery from the classic arcade game on your wrist. Instead of a second or minutes hand, the watch has three rotating discs that move asteroids, UFOs, and a triangular ship independently. The watch sells for $499 and comes in […]

It's only been a week since Chinese company DeepSeek launched its open-weights R1 reasoning model, which is reportedly competitive with OpenAI's state-of-the-art o1 models despite being trained for a fraction of the cost. Already, American AI companies are in a panic, and markets are freaking out over what could be a breakthrough in the status quo for large language models.

While DeepSeek can point to common benchmark results and Chatbot Arena leaderboard to prove the competitiveness of its model, there's nothing like direct use cases to get a feel for just how useful a new model is. To that end, we decided to put DeepSeek's R1 model up against OpenAI's ChatGPT models in the style of our previous showdowns between ChatGPT and Google Bard/Gemini.

This was not designed to be a test of the hardest problems possible; it's more of a sample of everyday questions these models might get asked by users.

Last summer, Anthropic inspired backlash when its ClaudeBot AI crawler was accused of hammering websites a million or more times a day.

And it wasn't the only artificial intelligence company making headlines for supposedly ignoring instructions in robots.txt files to avoid scraping web content on certain sites. Around the same time, Reddit's CEO called out all AI companies whose crawlers he said were "a pain in the ass to block," despite the tech industry otherwise agreeing to respect "no scraping" robots.txt rules.

Watching the controversy unfold was a software developer whom Ars has granted anonymity to discuss his development of malware (we'll call him Aaron). Shortly after he noticed Facebook's crawler exceeding 30 million hits on his site, Aaron began plotting a new kind of attack on crawlers "clobbering" websites that he told Ars he hoped would give "teeth" to robots.txt.

Apple-designed chips powering Macs, iPhones, and iPads contain two newly discovered vulnerabilities that leak credit card information, locations, and other sensitive data from the Chrome and Safari browsers as they visit sites such as iCloud Calendar, Google Maps, and Proton Mail.

The vulnerabilities, affecting the CPUs in later generations of Apple A- and M-series chip sets, open them to side channel attacks, a class of exploit that infers secrets by measuring manifestations such as timing, sound, and power consumption. Both side channels are the result of the chips’ use of speculative execution, a performance optimization that improves speed by predicting the control flow the CPUs should take and following that path, rather than the instruction order in the program.

A new direction

The Apple silicon affected takes speculative execution in new directions. Besides predicting control flow CPUs should take, it also predicts the data flow, such as which memory address to load from and what value will be returned from memory.

US Senator Ted Cruz (R-Texas) is trying to block a plan to distribute Wi-Fi hotspots to schoolchildren, claiming it will lead to unsupervised Internet usage, endanger kids, and possibly restrict kids' exposure to conservative viewpoints. "The government shouldn't be complicit in harming students or impeding parents' ability to decide what their kids see by subsidizing unsupervised access to inappropriate content," Cruz said.

Cruz, chairman of the Commerce Committee, yesterday announced a Congressional Review Act (CRA) resolution that would nullify the hotspot rule issued by the Federal Communications Commission. The FCC voted to adopt the rule in July 2024 under then-Chairwoman Jessica Rosenworcel, saying it was needed to help kids without reliable Internet access complete their homework.

Cruz's press release said the FCC action "violates federal law, creates major risks for kids' online safety, [and] harms parental rights." While Rosenworcel said last year that the hotspot lending could be implemented under the Universal Service Fund's existing budget, Cruz alleged that it "will increase taxes on working families."

Amid the Trump administration's abrupt, wide-scale freeze on federal funding, states are reporting that they've lost access to Medicaid, a program jointly funded by the federal government and states to provide comprehensive health coverage and care to tens of millions of low-income adults and children in the US.

The funding freeze was announced in a memo dated January 27 from Matthew Vaeth, the acting director of the Office of Management and Budget, and was first reported Monday evening by independent journalist Marisa Kabas. The freeze is intended to prevent "use of Federal resources to advance Marxist equity, transgenderism, and green new deal social engineering policies," Vaeth wrote. The memo ordered federal agencies to complete a comprehensive analysis of all federal financial assistance programs to ensure they align with the president's policies and requirements.

"In the interim, to the extent permissible under applicable law, Federal agencies must temporarily pause all activities related to obligation or disbursement of all Federal financial assistance, and other relevant agency activities that may be implicated by the executive orders..." Vaeth wrote.
