This month on Break It Down:
- Why are there over 8 million pickled fish in some WWII-era bunkers in Louisiana? We ask Tulane University Biodiversity Research Institute director Brian Sidlauskas to spill the tea.
- The discovery of the world’s oldest clothes predates the previous record holder by 9,000 years.
- We speak to Professor Hannah Fry about all things AI, including why one chatbot encouraged the assassination of the Queen of England.
- Some cave coral shows off its flashy burglar alarm.
- Scientists explain why building an enormous underwater wall could be the best plan to save the “Doomsday Glacier”.
- The mystery of why some people experienced blood clots following a specific kind of COVID vaccine has finally been solved.
- Curiosity finds the second most compelling evidence of life on Mars yet.
- Why scientists created a 228-meter popsicle that delves 23 million years into the past by digging deep beneath Antarctica.
- Conservation success as it’s announced we’ve successfully saved the Bermuda snail from extinction.
- Meet the people taking bold new approaches to the biodiversity crisis in creating a “de-extinction toolkit” that can benefit some of Earth’s most threatened species.
Plus, everything you can find in this month’s issue of CURIOUS, a teaser of a fascinating chat about games VS metrics with Professor C Thi Nguyen, and what do other worlds smell like? We sent our space editor to find out.
So, sit back, relax, and let’s Break It Down…

Deep-Space Toilet, Mega-Stegosaurus, And The Only Venomous Primate
Friday Jan 30, 2026
Friday Jan 30, 2026
This week on Break It Down: How a transplant patient lived for two days without lungs, the Artemis II Orion Capsule is probably smaller than you’re thinking (but it does have a toilet), the world’s only venomous primate is also super adorable, why a pair of giant legs has scientists questioning everything we thought we knew about stegosaurus, a cosmic miracle has been confirmed, and why do humans love fire? We asked the experts.
So, sit back, relax, and let’s Break It Down…

3I/ATLAS, CKM Syndrome, And Mosquitos’ Final Frontier
Friday Oct 24, 2025
Friday Oct 24, 2025
This week on Break It Down: a potential environmental trigger for autism has been identified, interstellar object 3I/ATLAS is doing weird things with its tail, 90 percent of people are at risk of a newly recognized syndrome, why we know the Denisovans didn’t hook up with the Jomon, as Iceland falls, mosquitos have just one place left on Earth they’ve yet to conquer, and why are people talking to “wind phones”? It’s all to do with “after-death communications”.
So, sit back, relax, and let’s Break It Down…

This week on Break It Down: 3I/ATLAS is a 10 billion-year-old time capsule, a world-first fossil captures the moment a rock hyrax dragged its butt 126,000 years ago, a living person received a pig liver transplant for the first time, the “oldest human habit” might not be what it seems, a rare gynandromorph spider is a 50/50 wonder, and what is this prehistoric creature with two heads? We asked a dinosaur expert.

Friday Sep 19, 2025
Friday Sep 19, 2025
This week on Break It Down: Homo habilis might not have been the apex predator we thought it was, the oldest and most complete pachycephalosaur reveals why they were so weirdly dome-headed, we’ve been able to track an asteroid’s full life story for the first time, nobody knows what these mysterious larvae grow up to be, humans are in the middle of an evolutionary transition, and what did Neanderthals sound like? Probably not what you think.

Friday Sep 05, 2025
This week on Break It Down: Queen ants are throwing the rules of reproduction out of the window by producing offspring of two different species, for the first time ever we have a complete map of brain activity and boy is it pretty, a new lineage of tropical mammoths have been discovered in Mexico, 150 million-year-old baby pterosaurs have been perfectly preserved thanks to some stormy weather, the controversy surrounding whether Homo naledi might have buried their dead is back, and we explore just how big the biggest egg on Earth really was.

Glowing Plants, Punk Ankylosaur, And Has The Wow! Signal Been Solved?
Friday Aug 29, 2025
Friday Aug 29, 2025
This week on Break It Down: Think you know Earth? Think again; a new campaign is trying to overturn the highly erroneous map we were all taught in school. A new injection can make succulents glow pretty much any color you like, and better yet, they’re rechargeable. An intriguing new theory to explain the legendary Wow! Signal makes a convincing case. Turns out the oldest known ankylosaur was also ridiculously spiky with a trait we’ve never seen in any vertebrate – living or extinct – before. See the first 3D digital analysis of the only person known to have a proton beam go through their head, and why does frozen seafood glow? Why indeed.
