Last week, the US government lifted its previous ban and formally approved the sale of Nvidia’s H200 chips, along with AMD’s chip line, to approved Chinese customers. Perhaps they aren’t the brightest, most cutting-edge chips from these chipmakers, but their exports are controversial because they are high-performance processors used for AI. And at the World Economic Forum in Davos on Tuesday, Anthropic CEO Dario Amodei blamed both the government and semiconductor companies for the decision. This criticism was particularly salient because one of those chipmakers, Nvidia, is a major partner and investor in Anthropic. “The CEOs of these companies are…
Elon Musk said over the long weekend that Tesla aims to resume work on the electric car company’s previously abandoned third-generation AI chip, Dojo3. Only this time, Dojo3 is not intended to train self-driving models on Earth. Instead, Musk said it would specialize in “space-based AI computing.” The move comes five months after Tesla effectively shut down its Dojo effort. The company has disbanded its Dojo supercomputer development team following the retirement of Dojo leader Peter Bannon. Approximately 20 Dojo employees also left and joined DensityAI. DensityAI is a new AI infrastructure startup founded by former Dojo director Ganesh Venkataramanan…
Differences in how intestinal cells respond to hormones may help explain why women experience more frequent and severe intestinal pain than men, a study in mice suggests.Irritable bowel syndrome (IBS) affects approximately 10% to 15% of people worldwide, and women are diagnosed with IBS up to twice as often as men. IBS symptoms such as pain, constipation, diarrhea, gas, and bloating often worsen in response to triggers such as stress or certain foods. However, the reasons behind the difference in IBS rates between women and men remain unclear.Now, researchers have discovered that estrogen, the main female hormone, can cause a…
Scientists have observed a supermassive black hole wake up from a nap of about 100 million years.A black hole is located at the center of a huge galaxy and emits extremely strong radio waves. New analysis of these radio emissions reveals that black holes once spewed giant jets of plasma hundreds of thousands of light-years into space, but that they suddenly ceased to be active at some point in the distant past. These jets are now active again and are interacting with the surrounding superheated gas in complex and chaotic ways, according to a new study.”It’s like watching a cosmic…
Luminar founder and former CEO Austin Russell has agreed to accept an electronic subpoena seeking his cell phone information related to the lidar maker as part of the lidar maker’s ongoing bankruptcy proceedings, according to a new filing Tuesday. Russell currently has seven days to file a motion to revoke or challenge the subpoena, or must otherwise respond within 14 days, according to the filing. The agreement comes two weeks after Mr. Luminar’s lawyers accused Mr. Russell of evading a subpoena by denying a process server at the gates of his Florida mansion. Russell claimed he was not willing to…

Two members of Elon Musk’s Department of Government Efficiency may have accessed and shared Social Security numbers last year to help an advocacy group “overturn election results in certain states,” according to court documents. The revelations, first reported by Politico, come as part of a series of corrections to previous testimony by Social Security Administration officials related to DOGE’s legal battle over access to Social Security data. Court documents do not name the two DOGE members or the advocacy group. In March 2025, a political advocacy group contacted two members of the Social Security Administration’s (SSA) DOGE team “requested to…
Online mentoring site UStrive has resolved a security flaw that exposed the personal information of users, including children.

The organization did not say whether it plans to notify users about the security incident. Last week, someone who requested anonymity alerted TechCrunch to a security flaw in UStrive’s mentoring platform. Anyone can see the stream of your…

They found that people who got just five extra minutes…
Amazon CEO Andy Jassy said consumers are starting to feel higher prices as sellers try to absorb additional costs from President Donald Trump’s tariffs. Jassy told CNBC that Amazon and many of its third-party sellers stocked up on inventory ahead of the tariffs to keep prices down, but most of that supply dried up last fall. “So some of the tariffs are starting to trickle down to some prices and some products, and some sellers are deciding to pass that higher cost on to consumers in the form of higher prices, some are deciding to absorb it to stimulate demand,…
