The week connected a warming trajectory to active disruption: emissions still track roughly 2 °C of warming, El Niño is intensifying, Swiss glaciers lost more than 5% of their volume, and 96% of assessed shallow-water reefs were classified as critically endangered.
New measurements put several foundations under scrutiny: precise helium readings sharpened tests of early-universe models, supernovae suggested that dark energy may evolve, and Bennu samples forced revisions to planetary formation models.
Japan launched its Phobos sample-return mission, while NASA kept Artemis III's planned docking exercise on track as a direct operational test of SpaceX's and Blue Origin's lunar landers.
The week linked precise neural control with new mechanisms of mitochondrial damage and a method for resetting age markers in cells. The findings expand experimental control over disease and aging while remaining short of clinical treatment.
Evidence this week connected hazards across timescales: glacier retreat helped amplify a modern Alaskan tsunami, an ancient asteroid impact generated a mega-tsunami, and Japan's Kikai caldera was found rebuilding its magma supply.
