I have an unpopular opinion: People over the age of 50 should be banned from politics and government. Just as we ban under 18s.

I can hardly think of anything more disgusting than eating Haribo or crisps while using a computer.😏

We did a perfect hike to Preikestolen as N Pact School participants. Particle physics, cosmology, and Norwegian fjords intersected in space-time.

I have been invited to a formal
dinner in Cambridge. As a first timer, it was great to dine in Hogwarts style dining rooms.

A fascinating morning talk on the origins of life, lunch with two professors, an inspiring JWST talk this afternoon, and great wine afterwards! 🌌🍷

My visit to Cambridge is going quite well beyond my expectations!

Unusual advantage of being from ‘the Middle East’: you are more likely to be the only author publishing with your last name (as in my case)😆

Everytime I pass through London's King's Cross, I don' forget to checkout this platform. I don't bother to wait in huge line to
my picture taken though:)

The last 3 years have been the hottest in around 125,000 years.

CO2 levels are their highest in MILLIONS of years.

But most people have no idea this is happening, let alone what it means for our kids’ futures.

Our politics & media have failed our children. We should be furious.

Cosmoverse@Istanbul was such a great conference where I had an opportunity to give a cosmology talk in my home country! More than a month now!

This is good to know.
On average, 86% of all named tropical systems in the Atlantic occur after August 2, and the first hurricane doesn't form until August 11.

Awesome!
Happy 4th! I made a patriotic pie, celebrating America's leadership in space sciences (historically).

Perseverance captured a new selfie to celebrate 1500 Sols on Mars.
The rover is currently investigating the outer rim of Jezero crater near an outcrop named Sally's Cove. #planetsci

Happy 99th birthday to the man who gave voice to the wild. 🎉

Sir David Attenborough, thank you for a lifetime dedicated to the natural world, and for sharing its story with wisdom, wonder, and grace.

You've inspired generations to fall in love with nature.

This is the point where science stands in the year 2025.

We have to be critical of almost any high impact claims nowadays.
The evidence for biosignatures on K2-18b is flimsy, at best

Last week, Cambridge scientists announced the discovery of DMS and DMDS on K2-18b: what they call a "surefire biosignature."

Now, cut through the hype and get to the truth.

The evidence for biosignatures on K2-18b is flimsy, at best
A Cambridge-based team claims to find molecules on an exoplanet that are only produced by life on Earth. Don't fall for the unfounded hype.
