A recurring idea is that modern life is poisoning us - chemicals, vaccines, industry are the primary drivers of poor health and reduced lifespan.

This depends on one assumption: longevity is mostly environmental, not biological.

I want to that challenge that assumption: 1/ When researchers separate deaths caused by accidents, infections, and violence from deaths caused by aging and age-related disease they find that about half of human lifespan variation is driven by intrinsic biology (genetics and aging). 2/

France banned the pesticide acetamiprid - before finding a single viable alternative.

Now farmers are losing up to 70% of their crops.

And imports treated with the same pesticide are flooding the market.

This is something we need to talk about🧵1/ INRAE - France’s own public research institute - just confirmed what farmers had warned:

The ban was political, not scientific.

Alternative methods are either less effective, more costly, or incompatible with real-world farming. 2/

You’ve been told microplastics are everywhere.

In your food.
In your blood.
Even in your brain.

You should panic.
You should rage.

But what if most of it was junk science? 🧵1/ This week, the EU Food Safety Authority (EFSA) reviewed 122 major studies on micro- and nanoplastics in food packaging.

Their verdict?

🚨 Most were deficient, unreliable, or corrupted.

Not our words. The EU’s top food scientists. 2/

Cancer patients who got a COVID shot lived significantly longer.

No, that’s not a typo.

A new study found that a simple mRNA vaccine - originally made for COVID - nearly doubled survival in patients with advanced lung and skin cancer.

Let’s break it down 👇 🧵 1/ Over 1,000 patients were studied.

Those who got a COVID mRNA vaccine within 100 days of starting immunotherapy lived much longer.

🟦 Lung cancer: survival jumped from 20.6 → 37.3 months.
🟪 Skin cancer: survival increased from 26.7 → up to 40 months. 2/

Every bite you eat is made of mutants.
Beautiful, delicious mutants.

Yes, even the organic ones. 🧬🍓

Let me explain why that’s not scary.
It’s the foundation of agriculture itself. 🧵 1/ 👉 Mutations are not accidents.
👉 They’re how we made food possible.
👉 Whether natural, induced, or edited, they fuel evolution - and dinner. 2/

After 8 billion doses - yes, 8 BILLION - COVID vaccines aren’t “experimental.”

They are one of the most tested medical interventions in human history.

Let’s talk about what that actually means. 👇🧵1/ 8 billion isn’t just a number.
It’s:

– More than all babies born in the last century.
– More than all global flu shots in a typical decade.
– A sample size so massive, even rare effects can’t hide 2/

Allergies affect 1 in 3 people.

The immune system goes haywire over harmless things - pollen, peanuts, pets.

But what if we could reprogram the immune system to stop overreacting?

Not suppress it. Not drug it.
Reprogram it.

A new mRNA therapy might do just that. 🧵1/ This isn’t science fiction.

Researchers just showed that mRNA lipid nanoparticles can prevent and reverse allergies in mice.

Yes - reverse.

Even in mice that were already sensitized.
No allergic reaction. No inflammation. No symptoms. 2/

The scariest thing about misinformation?
It doesn’t look like misinformation.

It looks like something you already believe.
That’s confirmation bias.

And it’s everywhere. 🧵 1/ Confirmation bias means this:

Your brain isn’t looking for what’s true.
It’s looking for what feels true.

You’re not searching for facts.
You’re searching for validation.

And algorithms know it. 2/

It is unbelievable that in 2025,
defending science has become an act of bravery.

Not because science has failed.
But because we have.

We let the loudest voices be the least informed. 🧵 1/ We live in a time when...

🌾 GM crops fed billions.
☢️ Nuclear energy kept lights on.
🧬 mRNA vaccines saved millions.
💊 TNF inhibitors gave people their lives back.

And yet…

It’s the conspiracy theorists who dominate the narrative. 2/

Yesterday, someone told me the safest policy in science is simple:

“If we’re not 100% sure something is safe… ban it.”

The crowd nodded.
It sounded cautious. Responsible.

But here’s the twist:
That’s the precautionary principle.
And it doesn’t always make you safer. 🧵1/ On paper, it looks perfect.
Don’t act until you’re certain.
Don’t approve until there’s zero doubt.

But life doesn’t work in certainties.
And the cost of waiting?

That’s the part nobody sees. 2/

You see it too, right?
Disinformation is flooding the feed.

Not subtle. Not clever. Just loud.

And it’s working.
Every day, the same formula: 🧵1/ ⚠️ A half-truth.
🔁 Amplified by bots.
🔥 Juiced by rage.
📢 Spread by people who think they’re “just asking questions.”

The result?
Confusion → Division → Paralysis. 2/

Bots aren’t just noise.
They’re the engine of disinformation.

Analysis of 1.269M accounts on X.
Result? 64% look like bots.

That means most of what you see in your feed…
…isn’t real people talking.

So how do bots push disinformation?🧵1/ It’s not by inventing new lies.
It’s by making lies louder.

➡️ Amplification:

A fringe claim gets retweeted thousands of times.

Now it looks “popular.”
Algorithms boost it even more. 2/

Disinformation isn’t random.
It follows a playbook.

And if you’ve been watching U.S. events lately, you’ve seen it in action. 🧵 1/ Step 1: Bots & Amplifiers
Sleeper accounts suddenly light up.

Fake followers boost the loudest lies.
What looks like “trending” is often manufactured. 2/

Veritasium's glyphosate video blew up.
Millions watched.

But it left out a lot of science.
And replaced nuance with drama.

Let’s fix that. 🧵👇1/ Main source? Carey Gillam.

She’s not neutral.
She’s spent years working with anti-GMO groups.
That’s like citing an anti-vaxxer to explain mRNA vaccines.

It’s not journalism. It’s advocacy. 2/

How do you “prove” that vaccines and Tylenol cause autism without real evidence?

There’s a whole playbook for manufacturing scary headlines.

Here’s how it works - and why it falls apart under real science 👇🧵 1/ 📈 Step 1: Draw Two Lines.

Plot autism diagnoses over time.
Plot vaccine use and Tylenol sales.

Both go up → “proof.”

Reality: Autism rates rose mainly because of better awareness + broader diagnosis.

Two lines ≠ cause.
Correlation ≠ causation. 2/

Just so we’re all on the same page…
“Do your own research” doesn’t mean research.
It means:

“Scroll until you find a post that confirms what you already believe.”

Let's talk about it:🧵👇1/ It used to mean:
→ Go to the library.
→ Read peer-reviewed studies.
→ Compare evidence and sources.

Now it means:
→ Watch a 3-hour YouTube video.
→ Follow a meme account.
→ Accuse scientists of lying. 2/

All joking aside…

It's insane how many people trust idiots over scientists.

And I know I’m not the only one who feels this.

Let’s break it down. 🧵👇1/ You study chemistry for 20+ years.
Work in a lab.

Publish peer-reviewed papers.

Then some guy with a ring light and a Rumble channel calls you a fraud - and people believe him. 2/

Have you met Bob?
He’s everywhere.

On TV, in Parliament, in headlines.
Bob is "The Precautionary Guardian".

He sees himself as the last line of defense between ordinary people and dangerous technologies. Pesticides, GMOs, chemicals - in his mind, they are lurking threats.

He has built a career out of warning people about them.

I met Bob one gray morning in London. We drunk coffee, and had a conversation I would never forget 🧵👇1/ Rain streaked down the glass walls of the Bundestag’s café. The place smelled of espresso and wet coats. I was early, nervous but steady.

I knew what Bob represented: a worldview that had shaped European politics for decades.

He arrived right on time. Tall, polite, almost scholarly in his composure. He shook my hand firmly, smiled warmly, and yet his eyes gave away his purpose. He wasn’t here for small talk.

We sat, coffee cups steaming between us. His black, mine with milk.

And then, without hesitation, the debate began. 2/

People who call scientists “shills”… are the same ones who trust random influencers with zero credentials
and a discount code in their bio.

Let me explain. 🧵👇1/ A scientist with 20 years in chemistry?
🧪 “Bought by Big Chemical.”

But a podcast bro selling detox tea?
✨ “Finally, someone brave enough to speak the truth.”

Make. It. Make. Sense. 2/

Spend 20 years studying a subject.
Go online. Get told you’re wrong by an electric screwdriver salesman…

🧵 Let’s talk about the collapse of trust in expertise: 1/ This isn’t just about bruised egos.
It’s about what happens when we flatten every voice to the same level…and ignore the difference between evidence and opinion. 2/

Science doesn’t care about your politics.

But RFK Jr. does.

And he’s turning public health into a battlefield.

Let’s talk about what weaponizing health really means - and why it’s dangerous.

🧵👇 1/ The CDC Director just got fired.

Why?

She refused to sign off on “reckless, unscientific directives.”
Her lawyer says RFK Jr. is using health policy as a political tool.

She’s not the only one speaking up. 2/
