Today we talk about the possibly first evidence for life on an exoplanet, with some caveats, chaos at the centre of the Milky Way, earthquake lights, a really old rock, noise cancellation for qubits, good news about air pollution, wifi that can see through walls, origami robots, the 2024 Breakthrough Prizes, and of course, the telephone will ring.

Today I talk about how we talk, or how we communicate information on social media in general. Why is it so difficult to communicate on social media, what’s a parasocial relationship, and what are the problems with it? Interestingly enough, it's a question that scientists have studied.

Today we talk about a bubble of galaxies, a climate scientist who made his own paper worse, double magic oxygen, a chemical reaction slowed down 100 billion times, Maxwell’s demon in biology, intelligent life on earth, the launch of a new X-ray space mission, drone racing, and of course the telephone will ring.

What is web3? I've tried to figure it out and here is my summary of what I have learned about NFTs and cryptocurrencies, about dapps and defi and blockchains, and all that.

I’ve noticed that a lot of scientists on social media make jokes about people who do their own research. This has been going on ever since COVID and it’s only been getting worse. We’re now at the point where they’re claiming you’re only allowed to talk about a topic if you’re an expert yourself. Don’t you dare commenting on anything you don’t have a PhD in! I think this nonsense has been going on for long enough. So I’m here to say: It’s of course completely okay if you do your own research, provided you do it right. But how do you do that? That’s what we’ll talk about today.
