This week’s episode is a reminder that science is basically a grab bag of “that’s amazing” and “please don’t make me think about that”. We’ve got flight attendants quietly racking up cosmic radiation exposure, lasers that can “smell” disease, NASA flirting with the idea of turning plastic into food, and a deep-sea stash of radioactive barrels that looks like the world’s worst scavenger hunt.

First up, the hidden cost of being nice at 30,000 feet. Flight attendants and aircrew aren’t just dealing with turbulence and weird passenger behaviour, they’re also exposed to higher levels of cosmic radiation because there’s less atmosphere protecting them at cruising altitude. It’s the kind of risk you can’t see or feel, which makes it easy to forget it’s even there.

Then we get into disease detection, featuring Joy Milne, who can literally smell Parkinson’s. Scientists have taken that idea and used lasers to detect chemical signatures our bodies give off, because those compounds can change when disease is present. It’s promising for earlier diagnosis, even if “belly button swab” is not a phrase anyone wanted in their life.

We finish with two flavours of “humanity, please”: turning plastic waste into edible protein for long space missions, and imaging radioactive waste barrels dumped on the ocean floor. The plastic-to-protein idea is gross but practical in a closed system, and the barrel footage is unsettling, even if early findings suggest radiation levels aren’t as catastrophic as you’d expect and marine life is still moving in.

This week’s episode is a reminder that science can make you feel tiny and powerful in the same breath. One minute we’re scanning the sky for signs of alien engineering, the next we’re looking at something that behaves like a star and a black hole at the same time, and then we’re back on Earth asking the least fun question of all: should we be building machines that can decide who lives and who dies?

First up, alien mega structures. We talk Dyson spheres, the idea that an advanced civilisation could wrap its star in solar collectors and turn a sun into a power station. You wouldn’t see the structure directly, but you might detect the heat it gives off, which is why Project Hephaistos is hunting for strange heat signatures that could hint at something artificial.

Then there’s the “black hole star”, which sounds made up but is very much being taken seriously. James Webb observations point to an object pumping out a ridiculous amount of energy, far beyond what normal nuclear fusion should allow. The leading idea is that it’s some kind of hybrid, where a black hole is involved in powering the light, which is not how we usually think of black holes behaving.

And finally, we land back on Earth with autonomous drones, where the vibe shifts from curiosity to ethics. These systems are moving beyond remote control and into selecting and engaging targets without direct human input, which raises the big question: if a machine makes the call, who’s responsible when it goes wrong?

This week’s episode is a reminder that humans will try to make money from anything, and nature will always be stranger than we expect. We jump from dinosaur bones as luxury investments, to an AI school that claims it can speed up learning, to a snake with a tail that looks like a spider, and then to crime patterns that change with the seasons.

First up: dinosaur fossils. Dinosaur skeletons are being bought and sold like high-end art, with buyers ranging from celebrities to finance types who want something rare for their collection.

Then we head to Iran for the spider-tailed viper, a snake that uses its tail like bait. The tail looks like a spider, so birds get curious and come closer, and the snake strikes. It’s clever, unsettling, and a good reminder that behaviour can be just as important as bones when it comes to evolution.

We also look at Alpha School, which says AI can help kids finish core learning in a couple of hours, then spend the rest of the day on skills and personal interests. It sounds exciting, but we keep one eyebrow raised, because, well, it’s called “Alpha School”.

We finish with seasonal crime, where burglary peaks in winter in the UK but summer in North America, and bike theft spikes in summer because that’s when bikes are everywhere and easiest to steal.
