SpaceX launches 13th Starship test flight, deploys 20 next-generation Starlink satellites
SpaceX on Friday launched its Starship rocket on its 13th test flight, sending the world's largest and most powerful launch vehicle into space carrying 20 next-generation Starlink satellites as the company advanced its plans for future Moon and Mars missions. The 407-foot (124-metre) rocket lifted off from SpaceX's Starbase facility in southern Texas after an earlier launch attempt was aborted last week when six engines on the first-stage booster failed to ignite. The company replaced the...
Sperm Whales blow bubbles to achieve restful, vertical sleep
Sperm Whales blow bubbles to achieve restful, vertical sleep New research from the University of St Andrews and Université de Neuchâtel, has uncovered the mechanism which allows sperm whales to sleep in a unique vertical position, just under the ocean surface. Sperm whales are the only whale known to rest vertically. It’s thought to enable them to sleep effectively by buffering them from surface wave action, while avoiding the energy needed to dive to deeper depths.

SpaceX's 13th Starship flight test launches with Starlink's next-gen satellites The Starlink satellites will burn up in the atmosphere 20 minutes later. Starship has taken off for its 13th test flight after a couple of delays due to unfavorable weather conditions. This is the first Starship flight to carry SpaceX's next-generation V3 Starlink satellites, which were designed to provide meaningful increases to its service's performance.
Response drift across frontier large language models
Announce Type: new Abstract: All frontier large language models (LLMs) exhibit response drift -- producing outputs that deviate from expert-validated references -- yet the magnitude and structure of this drift remain uncharacterised by systematic human evaluation. Here we report a fully crossed evaluation in which 47 geographically diverse participants each assessed all 62 multidomain questions across ten frontier LLMs under blinded conditions, yielding 29,140 independent assessments. Every...
