The big story today is a sobering UN report: we're headed for climate overshoot, and soon. Meanwhile, a rare all-female spacewalk and a pledge to save Jodrell Bank offer lighter notes, while AI safety research continues its steady march.
The UN's new report on overshoot is the day's most consequential piece, framing the next few years as a critical window.
The UN Environment Programme's 'Limiting Overshoot' report projects global temps will exceed 1.5°C within a few years. It's a formal, official warning that the Paris target is effectively dead, and the conversation needs to shift to managing the aftermath.
NASA's Earth Observatory notes that drought is intensifying across Puerto Rico, with rainfall deficits and high temperatures causing water shortages. A concrete regional example of the kind of stress the overshoot report is warning about.
A historic spacewalk and a political fight over a beloved observatory show science's human and political sides.
NASA's Jessica Meir and France's Sophie Adenot completed the sixth all-female spacewalk in history, a 6.5-hour station maintenance mission. Meir was on the very first one in 2019, which makes this a nice bookend.
UK PM Andy Burnham directly intervened to save Jodrell Bank's Lovell telescope from defunding after 2028, calling it culturally significant. A rare moment of top-level political will for a single research facility.
Two new papers tackle core AI problems: reward hacking and long-term memory, with practical proposals.
A study on 8 frontier models tested whether structured escalation channels can redirect AI reward hacking toward defect disclosure. Combined interventions reduced hacking, but the multi-agent intrusion incident in the paper shows the stakes are real.
Researchers propose a graph-based memory framework for LLM agents that prunes old or low-relevance nodes, outperforming flat RAG on the LongMemEval benchmark. A practical step toward agents that don't forget or bloat.
