A Chinese newsroom’s four-tool test found differing restrictions on celebrity likenesses, as a portrait-rights dispute puts permission and publication in focus.

A QEMU-based demonstration revives an unreleased app-switching design, separating Apple’s preserved software from the AI-assisted work needed to run it.
A Zhejiang University team led by Haoxing Xu reports in Science that TMEM184B and TMEM184C are the transporters that move calcium into lysosomes, answering a question open since 1991. The proteins refill lysosomal calcium without energy or acid, and a TMEM184B mutation linked to a neurodevelopmental disorder breaks the transport.
A Shanghai Jiao Tong University-led team reports in Science that the TLR4 immune receptor's TIR domain, long described as an inert scaffold, is a single-use enzyme. It cuts NAD+ into ADP-ribose and keeps the product as molecular glue that locks the inflammation signaling complex together. Mice without this enzyme activity all survived an endotoxin shock test.
OpenAI has disbanded its stand-alone robotics team, Fortune reported and OpenAI confirmed. Researchers move under Chief Research Officer Mark Chen, and applied robotics and hardware staff move to Greg Brockman's Applied organization. OpenAI says general models like GPT-6 Astra can now handle some robot tasks directly, so it no longer needs a separate robot brain.
