UN panel urges early limits on AI agents. In its first major assessment, a UN scientific panel warned governments to rein in increasingly capable AI agents before their risks are fully understood.

The panel's recommendation rests on the precautionary principle, the idea that governments should act on potential harms before scientific certainty exists. According to The Verge, the assessment applies that reasoning specifically to AI agents, arguing that safeguards should not be delayed until the systems' dangers are fully documented, since their capabilities are advancing faster than researchers' understanding of the associated risks.

Hidden chambers may lie beyond King Tut's tomb. A geophysical survey detected possible hidden chambers beyond Tutankhamun's tomb — potentially Nefertiti's long-sought burial place — though researchers caution it's too early for firm conclusions.

Nature, which reported the findings exclusively, characterized the geophysical survey data as 'tantalizing' rather than conclusive. The interest centers on Nefertiti, whose burial place has never been located; the readings raise the possibility it could sit adjacent to Tutankhamun's tomb. Researchers involved stressed that the data remain preliminary and that no firm conclusions about hidden chambers can be drawn at this stage.
