US chip exports controls have been a "failure", the head of Nvidia, Jensen Huang, told a tech forum on Wednesday, as the Chinese government separately slammed US warnings to other countries against using Chinese tech. Successive US administrations have imposed restrictions on the sale of hi-tech AI chips to China, in an effort to curb China's military advancement and protect US dominance of the AI industry. But Huang told the Computex tech forum in Taipei that the controls had instead spurred on Chinese developers. "The local companies are very, very talented and very determined, and the export control gave them the spirit, the energy and the government support to accelerate their development," Huang told media the Computex tech show in Taipei. "I think, all in all, the export control was a failure."

Each of our estimators is based on a simple, general approach to designing differentially private mechanisms, but with novel technical steps to make the estimator private and sample-efficient. Our first estimator samples a point with approximately maximum Tukey depth using the exponential mechanism, but restricted to the set of points of large Tukey depth. Proving that this mechanism is private requires a novel analysis. Our second estimator perturbs the empirical mean of the data set with noise calibrated to the empirical covariance, without releasing the covariance itself. Its sample complexity guarantees hold more generally for subgaussian distributions, albeit with a slightly worse dependence on the privacy parameter. For both estimators, careful preprocessing of the data is required to satisfy differential privacy.

Linear systems are the bedrock of virtually all numerical computation. Machine learning poses specific challenges for the solution of such systems due to their scale, characteristic structure, stochasticity and the central role of uncertainty in the field. Unifying earlier work we propose a class of probabilistic linear solvers which jointly infer the matrix, its inverse and the solution from matrix-vector product observations. This class emerges from a fundamental set of desiderata which constrains the space of possible algorithms and recovers the method of conjugate gradients under certain conditions. We demonstrate how to incorporate prior spectral information in order to calibrate uncertainty and experimentally showcase the potential of such solvers for machine learning.

Former United States President Joe Biden was not diagnosed with prostate cancer before last week, and received his "last known" blood test for the disease more than a decade ago, his office has said. The Biden camp's statement on Tuesday came as critics, including current President Donald Trump, stoked scepticism over the timing of the diagnosis, which has reanimated questions about whether the former president misled the public about his health while in office. "President Biden's last known PSA was in 2014," Biden's office said in the brief statement, referring to the prostate-specific antigen test used to detect prostate cancer. "Prior to Friday, President Biden had never been diagnosed with prostate cancer." On Monday, Trump said he was "surprised" that the public had not been notified about Biden's diagnosis "a long time ago".

Google has injected AI features into practically all of its products, now including Chrome. At Google I/O, the tech giant's annual event, Google announced that Gemini is coming to Chrome as it transitions into the generative AI era, antitrust issues be damned. Gemini's integration with the browser means users can ask questions about information on sites, or even navigate to those sites, while browsing the web. Gemini on Chrome will be available to Chrome users on Windows and macOS, but only for paying subscribers to Google AI Pro and AI Ultra plans, which cost 20 and 250 a month, respectively. Meanwhile, Google is in the remedial phase of its antitrust case, which the U.S. Department of Justice is prosecuting. Google has been ruled a monopoly for leveraging its Chrome browser in anti-competitive ways.

At Google I/O 2025, the company revealed a bunch of new Gemini updates and features that position the app as your AI assistant for practically everything. Today, Google announced a new Sora competitor called Flow, updates to your AI-powered researcher, and free Gemini Live. Free is the operative word here, since many of the other features are bundled into the paid subscription plans -- Google AI Pro (formerly AI Premium) for 20 a month and a new plan called AI Ultra for a whopping 250 a month. The features showcased today demonstrate AI's increasingly agentic capabilities, in other words, AI tools that can perform tasks on your behalf. "This is our ultimate goal for the Gemini app," said Google Labs and Gemini lead Josh Woodward in a pre-event briefing, "an AI that's personal, proactive and powerful."

Texas high school student Elliston Berry joins'Fox & Friends' to discuss the House's passage of a new bill that criminalizes the sharing of non-consensual intimate images, including content created with artificial intelligence. Parents love capturing their kids' big moments, from first steps to birthday candles. But a new study out of the U.K. shows many of those treasured images may be scanned, analyzed and turned into data by cloud storage services, and nearly half of parents don't even realize it. A survey of 2,019 U.K. parents, conducted by Perspectus Global and commissioned by Swiss privacy tech company Proton, found that 48% of parents were unaware providers like Google Photos, Apple iCloud, Amazon Photos and Dropbox can access and analyze the photos they upload.

Within seconds, you've been scanned, stored, and tracked--before even reaching airport security. Without ever handing over your ID, the Transportation Security Administration (TSA) already knows exactly who you are. This is happening at 84 airports across the US. And chances are, you didn't even notice. Marketed as a tool to enhance security, TSA's facial recognition system is drawing criticism for its potential to track Americans from the terminal entrance to their final destination.

The Take It Down Act, a controversial bipartisan bill recently hailed by First Lady Melania Trump as a tool to build a safer internet, is officially law, as President Donald Trump took to the White House Rose Garden today to put ink to legislative paper. It's the first high-profile tech legislation to pass under the new administration. "With the rise of AI image generation, countless women have been harassed with deepfakes and other explicit images distributed against their will. This is wrong, so horribly wrong, and it's a very abusive situation," said Trump at the time of signing. "This will be the first ever federal law to combat the distribution of explicit, imaginary, posted without subject's consent... We've all heard about deepfakes. I have them all the time, but nobody does anything. I ask Pam [Bondi], 'Can you help me Pam?' She says, 'No I'm too busy doing other things. But a lot of people don't survive, that's true and so horrible... Today, we're making it totally illegal."

A UFO slammed into a US fighter jet over Arizona, cracking the canopy protecting the pilot, and forcing the 63 million plane to land, new reports have revealed. According to the Federal Aviation Administration (FAA), the F-16 Viper fighter jet was hit by an'orange-white UAS' - which stands for uncrewed aerial system, better known as a drone - on January 19, 2023. Within a day of this collision, there were three more unidentified aircraft sightings over the Air Force's Barry Goldwater Range, where the fighter was damaged, the documents stated. Barry Goldwater Range is an expanse of desert along the Arizona-Mexico border where the military practices air-to-air and air-to-ground combat. The FAA's report of the F-16 collision revealed that the fighter was flying in restricted airspace near Gila Bend, Arizona, when it was hit by the object in the rear of the canopy, the glass bubble which protects the pilot.
