Europe is a cosy place. Not too warm in the summer, not too cold in the winter, not too wet and not too dry. But the climate in Europe depends strongly on the gulf stream, and for us over here, that the gulf stream stops or weakens is one of...
A group of Australian researchers has developed a microscopic sensor for nitrogen dioxide (a toxic component of gasoline car exhaust). It’s bar...

Welcome everyone to this week’s science news. Today we’ll talk about climate engineering, quantum computers, how to tell a nuclear bomb from TNT, what an atom really looks like, random keys from cosmic rays, who is filing the most patents...
Can the Gulf Stream collapse?
I stumbled onto this topic accidentally through my previous video on tipping points. I struggled a lot to get out "Atlantic Meridional Overturning Circulation" correctly and made a joke about my pronunciation trouble on twitter. In reply someone told me I coul...

Today I want to talk about something light.Hydrogen. Hydrogen is one of the currently most popular alternatives to fossil fuel in transport. Many companies and nations have put money into it. 2023-01-14 13:00:04 +0000 UTC View Post
Combine hydrogen with oxygen, add a little spark, and you get energy, plus water. It sounds like a great replacement for fossil fuels, but – as so often – it isn’t that simple. In this week’s video we talk about whether green hydrogen is really green, hydrogen embrittlement, and the impen...
2023-01-12 11:47:58 +0000 UTC View PostAt the end of November, the nuclear fusion mega-project ITER reported cracks in several parts of their containment vessel (Science News WTG, Nov 2022, Week 5). The n...

Welcome back everyone, I hope you had a good holiday break. We have quite a lot to talk about today, so buckle up. First, we have an anomaly in particle physics that disappeared and an anomaly in cosmology that was confirmed. Then we have some...

You may live in a different time-zone than I, but one hour for me is one hour for you. An hour might feel longer if it’s a job interview, but even the most awkward conversation doesn’t actually slow down time. And yet, Einstein said, time...
2023-01-07 13:00:06 +0000 UTC View PostI hope you all had a good start into the New Year! We will start it classically with a video about time dilation, the twin paradox, and Newton's bucket. It'll be fun, not one to miss!

Some topics we cover on this channel are a little heavy, so today I want to talk about something lighthearted. Human extinction. What’s the risk of human extinction and what are the biggest factors that contribute to the risk? That’s wha...

2022-12-29 20:15:59 +0000 UTC View PostTo wrap up the year, we have a particularly cheerful topic: human extinction. What are the greatest risks and what do we know about the risks? Fun fact: a survey found that one in five people thinks it wouldn't be bad if we went extinct. Not so fun fact: recent papers about the effects of a nucle...

Chaos control is not easy, as all parents knows. Indeed, it’s so difficult you might think it’s just impossible. After all, true chaos means that even the tiniest changes can have large and, in practice, unpredictable consequences. Like th...
2022-12-24 13:00:03 +0000 UTC View PostOne thing I am hoping to achieve with my YouTube channel is to draw attention to underappreciated scientific disciplines. The next video is about one of those: Chaos Control. Physicists have known that it's possible to control chaotic systems without just making them even more chaotic since the 1...

What should you do if you’re spending too much time on social media? Asking for friend. Well, you try to convince yourself that social media is actually good for, something. It’s got to be good for something, right? But they say that soci...
2022-12-17 13:00:03 +0000 UTC View PostI've read so much about how social media is supposedly bad for us. Echo chambers, polarization, fake news and whatnot. How much of this is opinion and what is backed up by science? We looked into it and it turns out social media isn't quite as bad as they say it is.

If you know one thing about quantum mechanics, then that’s more than most people. And it’s probably that it’s got something to do with the uncertainty principle. But just exactly what does that mean and how does it work? That’s what weâ...
It's about time we talk about quantum mechanics again! On Saturday I'll tell you all you need to understand Heisenberg's Uncertainty Principle. What does it mean that you can't measure two quantities precisely at the same time? What happens if you try? And is it really a quantum principle?

This is to say I'm sorry I forgot announcing what we're talking about this weekend: calorie labels. How much or how little do they really tell us...
