Getting high-quality sleep protects the brain. A new study shows that getting fewer than 5 hours of sleep per night may double the risk of developing dementia. Sleep activates the glymphatic system which cleans the brain of toxic metabolites and debris. t.co

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

Frames the idea around what the reader stands to lose, which is more motivating than gain.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

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

It’s embarrassing but the Jimmy Kimmel debacle actually is important. It was the first real attempt by the Project 2025 movement to flex their muscle against someone who wasn’t a nameless, defenseless nobody and it catastrophically flopped in less than a week.

So much cope about DeepSeek. Not only did they release a great model. they also released a breakthrough training method (R1 Zero) that’s already reproducing. I doubt they lied about training costs, but even if they did they’re still awesome for this great gift to the world.

Famously, human learning takes *very little* energy. A toddler learns thousands of words and an entire grammar while eating nothing but raspberries, before learning to read. An LLM needs a nuclear reactor and the entire internet as a training corpus.

First recovery in the ByBit hack. ~$43m (15,000 cmETH) has been clawed back from the hacker. I saw the recovery possibility soon after the hack and SEAL connected me with Mantle/mETH team who made it happen. Huge shoutout to SEAL, Mantle, and mETH teams for their quick action.

As shocking as the Kimi K3 release. Massive performance gain was just with post-training Model is 3x smaller than GLM 5.2 (10x smaller than K3) & works on a MacBook / Spark This is Q1 flagship (Opus 4.6/GPT 5.4) level for < $0.28/m tokens (100x cheaper)

Together with SpaceXAI, we’re training a significantly larger model from scratch, using 10x more total compute. With Colossus 2’s million H100-equivalents and our combined data and training techniques, we expect this to be a major leap in model capability.

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.

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.
