High‑altitude hypoxia curbs blood‑sugar spikes in mice
A mouse study found that low‑oxygen (hypoxic) conditions cause red blood cells to absorb far more glucose and convert it into a molecule that eases oxygen release, acting as a glucose sink. Mice exposed to 8% oxygen showed markedly smaller blood‑sugar spikes after glucose injections, and the effect persisted after they returned to normal air.
On February 12, United Launch Alliance’s Vulcan Centaur lifted off on the USSF‑87 mission but displayed a significant performance anomaly in one of its four solid rocket boosters. The anomaly, similar to the nozzle‑loss issue on the October 2024 Cert‑2 flight, prompted ULA to launch an investigation while the Space Force announced a pause on national‑security payloads until the cause is resolved. ULA had projected 16‑18 Vulcan launches in 2026, but the incident threatens that cadence. The launch occurred amid a leadership transition, with CEO Tory Bruno departing for Blue Origin and COO John Elbon serving as acting CEO.

The ESA‑CAS Smile spacecraft landed at the Guiana Space Centre on 26 February after a two‑week sea voyage aboard the cargo ship Colibri. Over the next weeks the probe will undergo health checks, propellant loading and integration with the Vega‑C launch...
