Aerobic exercise (half-hour workout 4-5x weekly) slowed the loss of brain volume in the hippocampus in elderly people with amyloid brain plaques and memory problems compared to those that did flexibility training only. 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

Leads with a specific number, which is concrete enough to be worth a second of attention.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Short enough to read in full without expanding, which removes a step before the point lands.

The mechanics

Hook: Leads with a number
Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: concrete
Mechanisms: Specificity
Written for: Founders, marketers and operators

Australia banned social media for children under 16. Some say the ban will protect kids from dangerous material, improve their mental health & help them get better sleep. Others argue it will increase social isolation & impede young people's free speech. What do you think?

As part of our $600B commitment, Mac mini will be produced in the US for the first time later this year! We're accelerating our progress even further— producing more AI servers and opening an all-new Apple Advanced Manufacturing Center for hands-on training.

Meta has committed ~$200B on AI Capex. There’s such a shortage of fiber technicians, it launched a free training program with CBRE. Beginning to think Meta is behind that “Data Centre” game on Steam where you buy racks, set up servers and install cables.

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.

What's more likely? 1 - small group of AI engineers at @deepseek_ai figures out how to beat all of the top researchers in the world as a side project 2 - Chinese government has 100k GPUs they shouldn't have and releases open source models claiming $6m training cost as a psyop

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.

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.
