Semaglutide extended lifespan 12% in old female mice
A Nature paper published Sep 2 found late-life semaglutide raised median lifespan about 12% in 20-month-old female C57BL/6 mice, from 742 days to 834 days. David Sinclair posted the paper; he is not an author. This is mice only. A human aging indication is unproved.

Apple streamed the first live MLB game in Vision Pro Immersive
Apple streamed its first live MLB game in Vision Pro Immersive on Aug 28, Yankees vs Red Sox at Yankee Stadium. The feed is a separate 8K production with about a 180-degree field of view, spatial audio, and dedicated announcers, not a TV wrap. Three more September dates remain. The $3,500–$4,100 headset, weight, and battery life still keep it niche. Claims about lapsed fans sitting through a full game are Brodie Brazil's read, not Apple's.

Y Combinator says Heart Aerospace flew the world's largest electric aircraft
Y Combinator's video recaps Heart Aerospace's first flight of the X1, which the film calls the largest electric airplane ever to fly: about a 100-foot wingspan, a 25,000-pound takeoff weight, and $5 of electricity. CEO Anders Forslund dates the flight to August 12 in Plattsburgh, New York. The production ES-30 is a hybrid-electric regional. The video itself gives two electric-range figures, 125 miles and 225 miles.

This is the third Flash drop in six weeks, three weeks after 3.7 Flash. The public model keeps the same introductory price as 3.7 through December 31: $0.75 per million input tokens and $3.75 per million output. Google says Flash Cyber scored about 86.2 percent pass@1 on CyberGym and 3.8 Flash scored 71 percent on Deep SWE 1.1; those are G
Computing
DHH says Omarchy is getting a full Apple Silicon installer
DHH says Omarchy is moving to a streamlined installer for Apple M machines, with a full announcement later today. Higgsfield says a phone can act as a virtual camera for AI video from a Blender scene. World Labs posted Atlas outputting explicit 3D from images, and Justine Moore showed a reshoot from a new angle. Install conversion and reconstruction claims are the labs' and posters' claims.

Anthropic released Claude Fable 5.1 and invite-only Mythos 5.1
Anthropic released Claude Fable 5.1 (generally available) and Claude Mythos 5.1 (invite-only trusted access for vetted cybersecurity and life-sciences work). Anthropic says they are the same model with different safeguards. Matthew Berman's capability rankings are his recap, not independently verified.

OpenAI says Astra is its first Critical cybersecurity model
OpenAI says Astra is the first model it has designated at the Critical cybersecurity capability threshold under its Preparedness Framework. The company says Astra can find unknown flaws and build exploits across hardened systems without step-by-step human guidance, and that stronger safeguards plus limited alpha access come with the release. Capability numbers and safeguard scores are OpenAI's own claims. Separately, Lauren shipped Dr Eggbot v0.2 with routine health checks for Grok Bots.

Thomson Reuters launched an LLM trained on 175 years of its own data
Thomson Reuters launched Thomson, an LLM that starts from Qwen3.5-397B and is trained on 175 years of the company's proprietary legal, tax, accounting, and news data. Zach Moskow said the company spent $40 million on it. Thomson Reuters' published benchmarks put the model near Claude Opus 4.8; those scores are the company's claim, not an independent test. Also in this pack: Kalpa TTS Beta v0.1 is listed No. 2 on Design Arena's Audio Realism Bench at Elo 1331, ahead of MAI-Voice-2 and Eleven v3 C

OpenAI's ChatGPT Work lead says teams should build two to three months ahead of the models
Lenny Rachitsky posted takeaways from Tara Seshan, OpenAI's ChatGPT Work product lead. Tara's heuristic is to build for where the models will be in two to three months, not for today's models or a year out. She also frames the future of work as steering, not rowing, and says OpenAI's culture asks whether teams are mainlining their own product. These are her comments as relayed by Rachitsky, not an OpenAI product announcement.
