Nuclear power used to be a conversation stopper. Luckily, we now all agree that it’s the fastest, safest, and most reliable way to get off fossil fuels. If it wasn’t for this little issue with the radioactive waste. Do you get superpowers if you roll around in it? If you came here to answer t...

Welcome to this week’s science news. Today we’ll talk about how to build a radio telescope – on the moon, recent wormhole headlines, the Artemis 1 launch and why it was delayed, quantum microscopes and the status of quantum computing, the first metaverse nation, manta rays, advances i...
I like to talk about nuclear power. This isn't new. New is that people actually listen to what I say. The renaissance of nuclear power has pushed forward technology development again, in particular when it comes to dealing with nuclear waste. How much nuclear waste is there, how much of a problem is it, and what can we do with it? On Saturday we...

Physicists have debated the role of consciousness in quantum mechanics for more than 100 years. Some podcast episodes will soon reach that length, but I have a dentist appointment in 2 hours, so we’ll have to wrap it up a little more quickly. Why did some physicists like von Neumann and Wigner think t...
2022-11-19 16:00:10 +0000 UTC View PostHere's a topic I have meant to talk about for a long time, but didn't quite know how to approach it: what's the relation (if any) between quantum mechanics and consciousness. Things clicked in place when I came across a paper earlier this year by two philosophers who were linking spontaneous collapse models with integrated information theory. Do...

Forget war, forget climate change, recessions, pandemics. Today we’ll talk about a real crisis. The decrease of testosterone levels. Just look at all those headlines. There must be something going on. But what? Are testosterone levels really falling? If so, why? And how much of a crisis is it? That’s what we’ll talk about today.

Welcome everyone to this week’s science news. Today we’ll talk about experimental evidence for quantum effects in the brain, the discovery of a potentially dangerous asteroid, a new method to track turbulence in plasma, China’s scientific Rise and the British Space Program, viruses on microplastics, how lasers can trick an autonomous vehic...
2022-11-10 16:01:00 +0000 UTC View PostThe sale of testosterone supplements is booming. Men seem to be popping the stuff like sugar pills. Headlines are screaming that testosterone levels are declining. How much of this is based on science? And should you tan your scrotum? On Saturday, we sort it out.

Quantum technology current attracts a lot of attention and money, which might explain why they’re missing on my end. But it’s not just governments who think quantum everything is where your taxes should go, business investors and companies are willing to putting in big money, too. This has had a dramatic impact on quantum physics research in...
2022-11-05 13:00:08 +0000 UTC View PostPhysicists heavily pin their hopes on quantum technologies as a way of demonstrating that foundational work in their field is still relevant for societal progress. Unfortunately, their unwillingness to clarify how limited the potential of some of those technologies is has resulted in the formation of a classical investment bubble. On Saturday I ...

2022-10-26 15:00:13 +0000 UTC View PostIn the past couple of years headlines have been popping up about "longtermists" that worry about human extinction and think we should focus more about the future expansion of human civilization than about the present. What do those longtermists want and why? On Saturday we'll look into it.

The cause comes before the effect. And I’m glad it does because it’d be awkward if my emails arrived before I’d written them. If that ever happens, it’ll be a case of “retrocausality.” What does that mean? What’s it got to do with quantum mechanics and what is the “transactional ...
2022-10-22 12:00:06 +0000 UTC View PostIt's been a few weeks that we've talked about quantum mechanics... So on Saturday we'll talk about a topic that's been on my mind for a few years, the question whether quantum mechanics is "retrocausal" and requires causes to go back in time. In particular we'll talk about Cramer's transactional interpretation and how that works.

Today I want to talk about personal energy storage. I don’t mean that drawer we all have that’s full of batteries in the wrong size, I mean our expanding waistlines that store energy in form of fat. What are the main causes of obesity, how much of a problem is it, and what are you to make o...

The video that's coming up on Saturday came about this way. I was trying to figure out whether plastic can possibly ...

Cold fusion could save the world. It’d be a basically unlimited, clean, source of energy. It sounds great. There’s just one problem: it’s not working. Indeed, most physicists think it can’t work even in theory. And yet, the research is making a comeback. So, what’s going on? What do w...

One thing I miss about the blogging days is the ability to comment on current events short notice. It's much harder with video than in writing. This is why on my YouTube channel, we now have a weekly Science News episode. I hope that this will make it easier to have a discussion about recent events!
2022-10-05 15:00:08 +0000 UTC View PostComing up on Saturday is a video I've been working on for a long time, low energy nuclear reactions aka cold fusion, reborn. There is much more to say about it than you'd think. Already one of my personal favorites.
“Flight shaming” is a social movement that originated in Sweden a few years ago. Its aim is to discourage people from flying because it’s bad for the environment. But let’s be honest, we’re not going to give up flying just because some Swedes think we should. I mean, we already shop at IKEA, isn’t that Swedish enough?
But seri...
Climate change has a side-effect that makes it very interesting, which is that it dramatically accelerates technological progress in some areas. Changes that would ordinarily have taken a hundred years now might come to pass within a decade. On Saturday we look at what's happening in the aviation industry and what plans they have to decrease the...

Like most videos on YouTube, this is a video about nothing. But we’re a science channel, so we’ll talk about nine levels of nothing. What are the nine levels of nothing? Can you really make a universe from them? And if someone asks you why there is something rather than nothing, what’s a good answer? That’s what we will talk about today....
2022-09-24 12:00:05 +0000 UTC View PostSo on Saturday we will talk about Nothing. That's Nothing with a capital N which you might say is quite something. Indeed I managed to talk about Nothing for 15 minutes. More seriously (but not too much) we'll talk about the 9 levels of Nothing and why there is something rather than Nothing, why it matters whether holes in cheese exist, and what...
