Welcome everyone to this week’s science news! Today we’ll talk about Trouble at ITER, robots that build robots, air pollution, AI that classifies supernovae, a small asteroid that hit Canada, Super GPS, a new supercomputer simulation of the sun, a quantum thermometer. And of course, the telephone will ring.

Nuclear Waste: What Do We Do With it?

[This is a transcript with links.]

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 that question, you’ve got the wrong channel. But we’ll talk about the next best thing to superpowers: numbers. How much nuclear waste is there, how...

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 in material design, the link between chaos and biodiversity. And of course, the telephone will ring.

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'll look into it.

Consciousness and Quantum Mechanics: What's the Link?

[This is a transcript of the video.]

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 that consciousness is necessary to make sense of quantum mechanics, and can consciousness influence the outcome of a quantum experiment? That’s what ...

Here'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. Don't worry if you have no idea what that means, I'll explain it on Saturday.

Welcome everyone to this week’s science news. Today we’ll talk about mysterious radiation bursts, a superfluid that supposedly recreates the early universe, good news from the Webb telescope, plans to intercept the next interstellar object, why you shouldn’t make things more complicated than necessary, a new device against tick bites, and the good and bad of social media.

Scientists believe that several radiation bursts str...

Why are testosterone levels falling?

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.

The worry that men are becoming too feminine isn’t new. It’s been in the newspapers since there’ve been newspapers. The blame has, among other thing...

Quantum Winter Is Coming

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 the past decade. It’s also created a lot of hype, especially around quantum computing. But if so much of quantum computing is hype then why are com...

Physicists 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 talk about what the problem is and what's likely going to happen when the bubble bursts.

What Do Longtermists Want?

Have you ever put away a bag of chips because they say it isn’t healthy? That makes sense. Have you ever put away a bag of chips because you want to increase your chances of having more children so we can populate the entire galaxy in a billion years? That makes… That makes you a longtermist. Longtermism is a currently popular philosophy among rich people like Elon Musk, Peter Thiel, and Jaan Tallinn. What do they believe and how crazy is it? That’s what we’ll talk about today.

What If the Effect Comes Before the Cause?

[This is a transcript of the video]

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 interpretation”? That’s what we’ll talk about today.

Causality is a relation between events in space and time, so I’ll be using space-t...

Coming up on Oct 22

It'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.

Why are we getting fatter?

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.

It happens frequently that I come across some headline on recent research and, as I try to figure out what to make of it, fall down a rabbit hole that leads to everything everybody else has ever said about this and related topics. The video that's coming up on Saturday came about this way. I was trying to figure out whether plastic can possibly be the cause of the obesity epidemic, as recent headlines claimed. And ended up doing a video on what we know about the causes of obesity to begin wit...

Cold Fusion is Back (there's just one problem)

[This is a transcript of the video.]

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 we know about cold fusion? Is it the real deal, or is it pseudoscience? What’s cold fusion to begin with? That’s what we’ll talk about today.

The First Ever Episode of Science News Without the Gobbledygook

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!

Can we make flying "green"?

“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 seriously, maybe the flight shamers have a point. If aliens come to visit us one day, how are we supposed to explain this mess? Maybe we should indeed try...
