Ozempic and Wegovy: All you need to know about the new weight-loss drugs

The weight-loss drugs Wegovy and Ozempic seem god-sent solutions for everyone who’s been struggling to lose weight, a miracle cure for a problem that befalls billions of people, even Elon Musk. But what makes the drug so effective? What do we know about it? And who’s going to pay for it?

Coin tosses are not fair -- science says so

Today we talk about why coin flips are not fifty-fifty, starquakes, the most powerful solar storm ever, space debris, IBM’s new brain-inspired computer chip, an exoplanet collision, a new tectonic plate, projections for AI power consumption, and of course the telephone will ring.

How does quantum mechanics give rise to parallel universes?

The idea of parallel universes has captured the imagination of many. In physics, it's prominently represented by the “Many Worlds” interpretation of quantum mechanics. In this video, I want to explain how the Many Worlds Interpretation works. Is it science? Does it solve any problems? And are the parallel universes real?

3 New Laws of Nature in One Week!

This week we talk about three new laws of nature, one of which supposedly shows that we live in a computer simulation. We’ll have a first look at intergalactic filaments, talk about building roads on the moon, whether chatbots understand what they chat about, a new type of qubit with a low error rate, sound waves in crystals, how to deflect lasers with nothing but air, dunes on mars, the first hurricane prediction market, and of course, the telephone will ring.

Is time travel possible?

What does physics say about time travel? Surprisingly enough it doesn't just say it's impossible, it's more complicated that that. In this video I'll sort out what Einstein's general relativity and quantum mechanics tell us about time travel. And is MIT really building a time machine to find dark matter? We'll get to that.

Planet Mercury is Shrinking

Today we’ll talk about a new candidate for a cosmic string, the mysterious shrinking of planet Mercury, a nuclear clock, the first quantum engine, a simulator for human diseases, whether we can find new physics with spinning black holes, AI that wants to help find aliens, how to compute with photons, and of course, the telephone will ring.

Physics Nobel Prize 2023 for Super-Short Laser Pulses

Today we’ll talk about the Nobel Prize in physics, yet another superconductor retraction, whether Integrated Information theory is pseudoscience, why antimatter doesn’t anti-gravitate, sand that flows uphill which I swear has nothing to do with antigravity, the world’s most powerful X-ray laser, how life could come about on other planets, why we might go extinct sooner than expected, and of course, the telephone will ring.
