Every frontier AI lab has lost co-founder(s): - OpenAI: 8 of 11 gone - Thinking Machines: 3 of 6 gone - SSI: 1 of 3 gone - DeepMind: 1 of 3 gone - xAI: 3 of 12 gone One exception: Anthropic. All 7 co-founders are still there. Anthropic culture is worth studying.

Valve wins lawsuit against Rothschild patent trolls. Amazon admitted failing to take down steam after trying for 15 years. Now NY AG is going after them... Are opening Pokémon cards gambling? Seems similar to cases. It's interesting timing is all...

so excited that @fidjissimo is joining openai in a new role: ceo of applications, reporting to me. i'll remain ceo of openai, but in this new configuration i'll be able to increase my focus on research, compute, and safety. these are critical as we approach superintelligence.

I think China's second DeepSeek moment is here. This AI agent called 'Manus' is going crazy viral in China right now. Probably only a matter of time until it hits the US. It's like Deep Research + Operator + Claude Computer combined, and it's REALLY good.

In last week's newsletter, I talked about how resistance training can support cardiovascular health in postmenopausal women. It's not just aerobic exercise! You can now read the issue - and sign up for free - in our archive. We send it out every week. t.co

Creatine is a supplement most women should be taking, especially post-menopause. 5 grams/day combined with resistance exercise increases lean mass and muscle strength but has inconsistent effects on bone mineral density. It makes productive training slightly more productive.

Five servings of fruits and vegetables per day may not be enough for heart health benefits. Only 20% of people who meet these guidelines have an estimated flavanol intake of 500 mg/day, a level associated with lower cardiovascular disease risk in randomized controlled studies.

This podcast is definitely going to be part of my regular listening queue. Congrats on the launch @mackinprof and @gibalam! Both are previous guests on the FoundMyFitness pod. I've learned so much from both.

I'd encourage everyone to grab a copy of Dr. Arthur Brooks' new book 'The Meaning of Your Life' or gift it to someone who might enjoy it (I plan to buy a few copies myself!) He shares so much wisdom on how to live a happy, fulfilling life.

Incredibly interesting result here. Combining rapamycin with exercise didn't help and may have even impaired exercise adaptations in older adults! Reminds me of metformin (also once marketed as a "longevity drug"), which also blunts exercise adaptations in certain contexts.
