2023/11/30

Welcome everyone to this week’s science news. Today we’ll talk about the leading theories for why Sam Altman got fired from OpenAI, cosmic rays with HUGE energies, evidence of a an overdue supervolcano eruption near Italy, an exoplanet on which it rains sand, Microsoft’s first AI-chip, why spiral galaxies like the Milky Way are so rare, how climate engineering could save the Antarctic, cannibalistic stars, and of course the telephone will ring. The quiz for this episode is here.

All you need to know about Long COVID

Science with Sabine ·

2023/11/30

Estimates say that as many as 1 in 10 people who had COVID were still affected more than 3 months later. This health condition has become known as long COVID. In this video, we will be discussing what long COVID is, how long it lasts, how common it is, what you should do if you think you’re affected, and more. This episode comes with a quiz which you can take here.

Is Science Dying?

Science with Sabine ·

2023/11/22

Is science coming to an end? On the one hand, it seems like scientific progress has slowed to a crawl and no big breakthroughs are happening any more. On the other hand, we are left with many unsolved problems in science that I am pretty sure have a solution. In this episode, I explain why I think that we need to seriously consider the possibility that we live in the final phase of scientific discovery.

Net Zero will Be Virtually Impossible To Reach...

Science with Sabine ·

2023/11/17

Everyone is talking about Net Zero. But Net Zero what? What does this even mean? Is it a reasonable goal? How far are we on the way? And do we have any chance of reaching it? For this video, we have collected all facts and numbers that you need to join the discussion. This episode comes with a quiz which you can take here.

New Data Spells Trouble for Dark Matter's Biggest...

Science with Sabine ·

2023/11/17

Today we have an update on the biggest astrophysics drama of the year, that’s an observation which seems to be ruling out the most popular alternative to dark matter. Then we have a group of geologists who claim that parts of the moon are stuck in the mantle of earth, a new and quite plausible explanation for the sudden dimming and brightening of the star Betelgeuse, plans for a smaller and more energy-efficient particle collider, the first full colour images from the EUCLID mission, earthquakes in

Science with Sabine ·

2023/10/30

The weight-loss drugs Wegovy and Ozempic seem god-sent solutions for everyone who has 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? This episode comes with a quiz which you can take here.

Three New Laws of Nature in One Week!

Science with Sabine ·

2023/10/20

Welcome everyone to this week’s science news. This week we’ll 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

Is time travel possible?

Science with Sabine ·

2023/10/15

What does physics say about time travel? Surprisingly enough it doesn't just say it's impossible, it's more complicated than 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. This video has a quiz which you can take here.

Quantum Computing in 2023: Three Newcomers

Science with Sabine ·

2023/10/08

What if we could harness the power of photons to process information? We can! It's called photonic computing. It's one of the new approaches to quantum computing - and it's looking more and more likely that it could be the key to make quantum computers work. It's not the only newcomer. In this video, we'll take a look at photonic computing and two other newcomers: optical tweezers and topological quantum computing. Maybe the breakthrough for quantum tech is just around the

Is the universe pointless?

Science with Sabine ·

2023/09/24

If people knew one thing about Steven Weinberg, it’d be a quote from one of his books: “The more the universe seems comprehensible, the more it also seems pointless.” In this episode, I want to speculate about what he might have meant. Is the universe pointless?

Don't trust me, I'm an influencer!

Science with Sabine ·

2023/09/16

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.
