Drug discovery is one of the most expensive failures in modern industry. Finding a single viable molecule can take a decade and cost billions, and most candidates still don’t make it. A generation of AI startups has promised to fix that — most have made the problem less painful for researchers, who are already technically…

A worker died at SpaceX’s Starbase launch site in South Texas on Friday, and the Occupational Safety and Health Administration (OSHA) has opened an investigation. The San Antonio Express-News reported Monday that the unidentified victim died at around 4:17 a.m. local time on May 15, citing OSHA and local officials. The Wall Street Journal later…

As LLM-powered agents move from research to production, one design tension is becoming harder to ignore: the more useful cloud-hosted memory becomes, the more private user data it exposes. Researchers from MemTensor (Shanghai), HONOR Device and Tongji University have introduced MemPrivacy, a framework that attempts to resolve this tension without sacrificing the utility that makes…
