Scientists tracked 25,315 women for 25 years.

Those who followed one eating pattern had 23% lower risk of dying from anything.

Not a fad. Not restriction. A 4,000-year-old diet backed by the largest nutrition trial ever run.

Here's exactly what I'd eat (and avoid): 🧵 1/ The pattern: Mediterranean diet

But not the watered-down version you see in magazines.

The real protocol is built on one core principle:

Reduce chronic inflammation, the silent driver behind heart disease, cancer, and early death. Image

Andrew Huberman found something that gives him more peace than cold plunges, meditation, or any protocol he's ever shared.

He does it every morning. Sometimes in the middle of the night.

Most scientists won't talk about it publicly.

Here's what it is: 🧵 Image

Prayer.

Every single night, @hubermanlab gets on his knees beside his bed.

"Like an old kid in a movie," he says.

But the science behind why this works is anything but childish.

The real reason some people have unbreakable willpower…

Isn't discipline.

It's a brain structure most people have never heard of. It only grows when you suffer. And it might predict how long you live.

Here's what Stanford neuroscientists discovered: 🧵 Image It's called the anterior mid-cingulate cortex. The aMCC.

Stanford neuroscientist @hubermanlab calls it "one of the most important discoveries in the history of neuroscience."

And it changes everything we thought we knew about willpower.

The fastest way to calm your nervous system…

Isn't meditation.

It's something far simpler, and you've been doing it unconsciously your whole life.

Here's the 2-minute protocol that boosts nitric oxide 15x & activates your vagus nerve: 🧵 Meditation works. But it takes time to learn and even longer to feel results.

There's something far simpler that activates the same calming pathways in your body.

You've been doing it since childhood without realizing it.

It's humming.

She predicted:

• The Deep Learning revolution (2012)
• AI's blindness to the physical world (2018)
• The shift to world models (2024)

Now Fei-Fei Li revealed the 5 next AI waves reshaping every physical industry.

Here's what you should know (& how to position yourself): 🧵 Image First, her track record:

Li created ImageNet, the dataset that triggered the AI revolution.

She leads Stanford's Human-Centered AI Institute. Her startup World Labs just raised $230 million.

When Li makes predictions, the entire AI industry pays attention.

A $0.15 amino acid just outperformed prescription sleep meds.

3g before bed = better cognition & alertness than 8hrs normal sleep.

Double-blind trial. No side effects.

Here's what 99% of doctors don't tell you: Image The amino acid is glycine.

And it's been hiding in plain sight for decades.

While Big Pharma pushes $400/month prescriptions with nasty side effects, this 15-cent solution has been sitting in research journals since 2012. Image

Sleep scientists just dropped a bombshell study.

And they're NOT talking about pills or trackers.

A 15-min ritual beats $400/mo prescriptions:

- 50% faster sleep
- Kills anxiety
- $0 cost

Here's everything you need to know: 🧵 Image The study tracked thousands of people struggling with insomnia.

Half got prescription meds. Half got a structured bedtime routine.

90 days later, the routine group wasn't just sleeping better, they were sleeping faster with zero side effects. Image

13 major companies have been caught red-handed with AI disasters since 2023.

They've paid millions in penalties and settlements.

But the media won't touch it.

Here's the disturbing pattern Big Tech doesn't want you to see: 🧵 Image Samsung. Deloitte. Workday. Air Canada.

These aren't startups making rookie mistakes.

These are Fortune 500 companies bleeding millions from AI failures.

And the disasters are accelerating... Image

Dr. Matthew Walker just went viral for exposing the truth about sleep science.

And he's NOT just talking about getting 8 hours.

He revealed genetic short sleepers, why your magnesium is useless, and the first sleep drug he actually recommends...

Here's what you missed: 🧵 Image 1/ The Magnesium Myth

Most forms of magnesium (oxide, citrate) don't cross the blood-brain barrier.

And sleep is produced by your brain.

Walker's verdict? "All you're doing is creating expensive urine."

Only magnesium L-threonate shows evidence—and only if you're deficient.

BREAKING: Salesforce's $200B company ran a 9-month AI experiment.

They gave AI agents access to their entire customer support, engineering, and sales.

Result: 1 million conversations. 360,000 hours saved.

But what Marc Benioff admitted on camera changed everything:

THREAD🧵 Image Marc Benioff promised 1 billion AI agents by year-end at Dreamforce.

Inside Salesforce right now: AI does 30-50% of work in engineering and support. 1,000+ jobs cut. No more coders hired.

This isn't a pilot. It's workforce replacement at scale.

Harvard just proved bedroom temperature controls sleep quality.

Participants fell asleep in 6.2 minutes when cool vs 20 minutes when warm.

Yet most people still don't optimize this simple factor.

Here's the exact temperature range that triggers deep, restful sleep: 🧵 Image Your core body temperature is the key.

When it drops by just 1°F, your brain floods with melatonin and initiates deep, restorative sleep.

Harvard researchers stumbled upon this when they noticed something strange...

Elon Musk's new interview with Joe Rogan just went viral.

And he's NOT just talking about SpaceX or Tesla.

Instead, he revealed what terrifies him most about AI... and it's not the technology itself.

Here are 8 shocking insights from their 3-hour conversation: 🧵 Image 1/ Instilling The Right Values In AI

@elonmusk's biggest fear isn't AI becoming too powerful. It's forcing AI to believe things that are false.

"If you tell AI that diversity is most important and misgendering is worse than nuclear war... you get very dystopian outcomes."

Blue Light exposure at night is quietly destroying your health.

It accelerates aging, chronic fatigue, and even weight gain.

Since 70% of adults have exposure to blue light at night...

Here's what you should probably know and the ONE habit that will slow down aging rapidly: 🧵 Image Most people think it's just about sleep quality.

They're wrong.

What's happening inside your body when you scroll at 11 PM is far more dangerous than anyone realizes...

This is Satchin Panda.

He's a biology professor who's studied circadian rhythms for 20+ years.

His message? Your body has an internal clock—and ignoring it causes diabetes, weight gain, and early aging.

Here are 6 timing tricks to sync your circadian rhythm: 🧵 Image Panda is a professor at the Salk Institute in California.

In 2002, he co-discovered melanopsin, a blue-light sensing protein in your eyes that controls your master biological clock.

This discovery was named one of Science magazine's top 10 breakthroughs.

This is Andrej Karpathy.

Former Tesla AI Director who built their self-driving system from scratch.

He just spent 3 hours with Dwarkesh Patel revealing mind-blowing truths about AI that 99% of people wouldn't know...

Here are 9 insights that will change how you think about AI: Image 1/ Why It's The Decade of Agents (Not The Year)

Karpathy's reaction to AI hype: "We'll be working with these things for a decade."

Current agents lack intelligence, multimodality, and continual learning.

"They're cognitively lacking and it's just not working."

BREAKING: Google paid out $430K to researchers finding AI vulnerabilities & one pattern kept repeating.

Every AI system they tested had the same critical weakness. And attackers already know what it is.

Here's what they found:

(hint: it's not the technology that's broken) Image The AI security war is already here.

Cybercriminals are using AI to launch attacks 40% faster than before. 85% of all cyberattacks now leverage artificial intelligence.

But defenders are losing—and not for the reasons you'd expect. Image
