Exciting update on our #EEG study of selective memory retrieval! Led by @moccia_arianna - story below

[Tony Vaughan KC MP @tonyvaughanMP]

The Prime Minister said in September that we are at a fork in the road. These asylum proposals suggest we have taken the wrong turning.

The idea that recognised refugees need to be deported is wrong. We absolutely need immigration controls. And where those controls decide to grant asylum, we should welcome and integrate, not create perpetual limbo and alienation.

The rhetoric around these reforms encourages the same culture of divisiveness that sees racism and abuse growing in our communities.

The Government is wrong to think that reviews of safety in the person's country every few years will mean refugees can be returned at scale. That hasn't happened in Denmark. Brutal dictators tend to hang onto power. It would just move huge amounts of resource away from making our asylum system work as it should - by cutting initial decision delays and the appeals backlog, sorting out asylum accommodation, making the UK-France deal work, removing those whose claims fail etc.

The Government must think again on this.

I’m a chemist. And I need to say this - because it’s getting dangerous out there.

The biggest health myth in the world isn’t about vaccines. Or GMOs. Or fluoride.

It’s the root of all of them.
It’s called chemophobia - and it’s killing science.

Fear of “chemicals” now drives vaccine rejection, GMO bans, food hysteria, and entire political movements.

From tampons to tap water, people have been taught to fear chemistry - the very thing that keeps us alive.

Chemophobia tells us:
“Natural is good.”
“Synthetic is bad.”

That’s a lie.

Botulinum toxin is 100% natural and one of the deadliest molecules known.

Aspirin is synthetic and life-saving.

We’ve gone from banning harmful substances for good reason…to banning safe, well-tested molecules for emotional reasons.

You’ve seen the slogans:

“If you can’t pronounce it, don’t eat it.”
“Paraben-free.”
“Clean beauty.”

They sound empowering. But they’re not science - they’re marketing.

And they’re making the world dumber, poorer, and sicker.

Your body doesn’t care if a molecule comes from a plant or a lab.
Vitamin C is vitamin C.

Formaldehyde is formaldehyde and your body makes more of it every day than any vaccine ever could.

Dose matters. Source doesn’t.
This fear isn’t harmless.

It shapes public policy.
It blocks innovation.
It raises food prices.
It slows down cancer treatments.

Chemophobia is now mainstream and it’s costing lives.

Scientists aren’t losing because we’re wrong.

We’re losing because fear spreads faster than facts.

Because influencers sell fear for clicks.

Because lawyers monetize doubt.

And because scientists are too tired to fight back.

So here’s my message, as a chemist and as a citizen:

🧪 Learn how toxicology works.
📣 Call out chemical fear-mongering.
✅ Support policies based on evidence, not emotion.

Chemistry isn’t the enemy.
It’s the reason you have clean water, safe food, and modern medicine.

If we let fear win, we lose all of it.

Our attention waxes and wanes over time. How does this influence the way our memories are organized?

Pupil size at encoding, an index of attention, predicts the temporal structure of subsequent memory
