Alien Mega Structures, Black Hole Stars and Autonomous Drones

This week’s episode is a reminder that science isn’t just lab coats and breakthroughs. It’s also weird human behaviour, messy systems, and the occasional moment where you realise an entire industry is making bank off… a PDF. We’re talking academic publishing as a toll road, Rapunzel Syndrome turning a fairy tale into a medical emergency, and what babies seem to expect from the world before they can even talk. First up, academic publishing. Scientists do the research, reviewers do the reviewing, universities pay for the work, and publishers still charge huge fees to publish or read it, with big players pulling in massive sums through processing charges. The kicker is that a lot of it is publicly funded, so taxpayers often pay for the research and then pay again to access it. Then we get into the human side of things, from compulsive hair eating that can become life-threatening (Rapunzel Syndrome), to experiments suggesting babies expect comfort when they cry and show stress when they don’t get it. We also touch on out-of-body experiences that don’t perform better than chance in controlled tests, and the messy reality of psychiatric diagnosis, where rigid labels don’t always match real lives.

This week’s episode: Roman concrete. The Pantheon has been standing for roughly 2,000 years with a huge dome made of unreinforced concrete, and it’s still in better shape than plenty of modern buildings. The Romans used volcanic ash and quicklime, and the chemistry seems to keep strengthening the material over time. Researchers think it may even “self-heal”, with minerals like calcite forming and filling tiny cracks as water moves through.

This week’s episode is a reminder that science news is basically three genres on rotation: animals behaving badly, humans believing wild things with full confidence, and researchers doing work that sounds like a plot twist in a sci‑fi novel. We’ve got dolphins running ocean heists, urine therapy finding new ways to stay alive online, and mice with human brain cells making everyone quietly ask, “Are we sure we’re comfortable with this?” First up, dolphins. There are reports of them stealing fish from seabirds mid-hunt, which is already rude, but it can get even stranger when you look at what counts as “food” in the ocean. This is where kleptoparasitism comes in, the polite term for stealing someone else’s meal, including forcing prey to regurgitate and then grabbing the half-digested leftovers. Then we move to urine therapy, which refuses to die on the internet despite being widely debunked. Online groups still treat it like a miracle health hack, and some people are now trying to use AI as a validation machine. When chatbots push back, they rephrase prompts or wrap them in poetry to slip past safety filters and get the answer they want. Finally, we get to the research that makes you sit back a bit. Scientists are experimenting with mice that have been given human brain cells to study brain development and neurological disease. The aim is medical insight, but it still raises the bigger question about where the ethical line sits, and how we stop “we can” from automatically becoming “we should”.

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.

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.
