Children up to 1 yrs old had ~53 minutes of screen time daily & more than 150 min at 3 yrs. Previous research has found that children who have more screen time have lower white matter integrity in parts of the brain that support language/literacy skills. t.co

From likes, comments.

Why it worked

Leads with a specific number, which is concrete enough to be worth a second of attention.
Short enough to read in full without expanding, which removes a step before the point lands.

Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: plain, matter-of-fact
Written for: Founders, marketers and operators

We've raised $65 billion in Series H funding at a $965 billion post-money valuation, led by @AltimeterCap, Dragoneer, @Greenoaks, and @sequoia. This investment will help us advance our research and expand our capacity to meet growing demand for Claude.

Meta laid off 600 people from its Superintelligence Lab today. Many FAIR researchers, including FAIR Research Scientist Director Yuandong Tian, were affected. I think Yann Lecun will leave soon. Maybe I should raise $2B and start a new frontier lab with these folks.

Our teams have been building with a 2.5x-faster version of Claude Opus 4.6. We’re now making it available as an early experiment via Claude Code and our API.

i'm not satoshi, but I was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas.

Huh? You bailed in the middle of trial after cutting a sweetheart deal with Live Nation, tried to pressure the rest of us to accept it, but we pressed on and won the trial without you. Congrats to consumers, not to you.

More from Dr. Rhonda Patrick

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

Dr. Rhonda Patrick

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.

Dr. Rhonda Patrick

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.

Dr. Rhonda Patrick

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.

Dr. Rhonda Patrick

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.
