We develop a natural Bayesian multiplicity-correcting prior distribution within the probabilistic forward stepwise representation of model space priors for regression problems. The proposed prior, obtained from making an analogy to the Holm procedure, exhibits behavior closely aligned with that of the Matryoshka doll prior. We compare both priors to several other priors, including some recently put forward as objective choices for model space prior probabilities. Our comparisons indicate that adequate multiplicity correction requires a degree of sparsity that many recommended priors do not provide, and we argue that multiplicity correction itself offers a principled and transparent criterion for specifying model space priors in regression.

People visit an Alibaba booth during the World Artificial Intelligence Conference in Shanghai on July 26, 2025. China is restricting overseas travel for top AI professionals in private firms such as Alibaba Group and DeepSeek, suggesting an escalation in measures intended to safeguard its technology and catch up to the U.S. in a pivotal sphere. Government agencies have begun imposing restrictions on individuals involved in advanced AI work and considered strategically important to the country, people familiar with the matter said. That means they need approval from relevant authorities before embarking on overseas travel, the people said, asking for anonymity to discuss a sensitive issue. Beijing has for years imposed travel restrictions on key personnel from prominent college researchers to nuclear scientists and executives at state firms.

One line tucked into a federal highway bill would strip funds from cities and states unless they kill their automated plate tracking programs--effectively banning the tech for all but toll collection. US lawmakers plan to introduce an amendment Thursday at a House committee markup hearing that would prohibit any recipient of federal highway funding from using automated license plate readers for any purpose other than tolling--a sweeping restriction that, if adopted, would bring an immediate end to state and local ALPR programs across the United States. The amendment, obtained first by WIRED, is sponsored by Representative Scott Perry, a Pennsylvania Republican and Freedom Caucus member, and Representative Jesús "Chuy" García, an Illinois progressive whose state has become a flash point in the national fight over ALPR misuse. The House Transportation and Infrastructure Committee will mark up the underlying bill--a $580 billion, five-year reauthorization of federal surface transportation programs--at 10 am ET on Thursday. Neither Perry nor García's offices immediately responded to WIRED's request for comment. The amendment runs a single sentence: "A recipient of assistance under Title 23, United States Code, may not use automated license plate readers for any purpose other than tolling."

United States President Donald Trump has departed for Beijing ahead of a high-stakes summit with Chinese President Xi Jinping, after weeks of unsuccessful US efforts to persuade China to help bring Iran back to negotiations and ease tensions around the Strait of Hormuz. The leaders of the world's two largest economies are due to meet on Thursday and Friday during Trump's first visit to China since 2017, with talks expected to focus on trade, Taiwan, artificial intelligence and the war involving Iran. Why does the Trump-Xi summit matter? The Trump-Xi summit is a high-level meeting between Trump and Xi Jinping taking place in Beijing as the world's two largest economies face growing tensions over trade, technology, Taiwan and the Iran war. The summit is particularly significant because Trump will be the first US leader to visit China in nearly a decade, while the talks also come at a time of heightened geopolitical and economic uncertainty.

To stop children from bypassing its age checks, Meta is revamping its age-verification tools with an AI system that analyzes images and videos for "visual cues," such as height and bone structure. Meta is beefing up its age-verification mechanisms with an AI system that analyzes images and videos on Instagram and Facebook for "visual cues," such as height and bone structure, to identify and delete accounts of users under the age of 13. The company announced the move amid a wave of cases in which hundreds of children have managed to evade social network access restrictions, even through simple tricks such as drawing on a mustache. The new approach is part of a series of measures Meta adopted as part of an AI-based security strategy designed to correct the limitations of traditional methods, which rely heavily on self-reported age. With this change, the company seeks to reduce the ease with which minors access platforms that, in theory, are restricted to them.

China will ban the sale of drones in Beijing and require permits to fly them under new rules that take effect on Friday. Drones and key components will be prohibited from being sold, rented or brought into the Chinese capital. Drone owners will also be required to register their devices with the police. China has gradually tightened regulations on drones in recent years, with authorities citing public safety concerns. Drones and flying taxis are part of the so-called low-altitude economy, a strategic priority for China that is expected to generate more than two trillion yuan ($290bn; £217bn) by 2035.
