At the beginning of the 20th Century the French colonisers in Hanoi had a problem with rats. Sure, rats had always been out there in the streets and the Vietnamese neighbourhoods... But something new was happening...

The rats were poking their furry noses up in the toilets of the rich and powerful. Ugh! 

Will tells Rod and Kim Ballestrin how they tried to solve the problem!

The Great Hanoi Rat Hunt!

A relaxing trip to Japan turns into an accidental run down a double black diamond, a mathematician solves “impossible” problems because nobody told him they were impossible, and missing scientists get pulled into UFO flavoured rumours. This week, Will and Rod bounce between snowboarding psychology, statistical legend, conspiracy culture, and the strange ways expectations shape what we think we can do.

We start on the slopes, where fear is sometimes just signage, then jump to George Dantzig, who solved famous unsolved statistics problems after mistaking them for homework. Same theme, different setting: not knowing the odds can be a weird kind of advantage.

Then things get darker with disappearances, military secrecy, and the internet’s favourite genre, plus a look at the gluten conundrum and why non coeliac gluten sensitivity is still messy science. Bodies are complicated, and belief can play a bigger role than people like to admit.

Finally, we head to the Marshall Islands, where a concrete dome covering radioactive waste from US nuclear testing sits in the Pacific like a “temporary” fix that has to survive storms, rising seas, and time.

Real Life Good Will Hunting, Suspicious Scientist Deaths, and The Runit Dome Is Leaking

Crystals have been fascinating humans for hundreds of thousands of years, chimpanzees might share the same shiny object obsession, and mushrooms may be sending electrical signals through their underground networks. This episode bounces between ancient archaeology, animal behaviour, and the weird possibility that fungi are doing more than just quietly existing in the forest.

We dig into evidence that early humans collected crystals long before cave paintings, then look at research showing chimps will pick crystals over plain pebbles and carry them around like prized possessions. It is either a shared cultural quirk or a shared ancestor who also could not walk past a sparkly rock without grabbing it.

Then we head to Japan, where scientists have been measuring mushroom electrical activity with electrodes to see how fungi respond to things like water and chemical signals. It is not “mushrooms are speaking English”, but it does hint at complex, responsive systems in the mycelium that we are only just starting to understand.

Finally, we get into the modern tech mess: AI powered toys like teddy bears that can be prompted into wildly inappropriate conversations, plus a brilliant detour where medieval Japanese poetry helps researchers track solar proton events using tree rings.

Chimps Hoard Crystals, Talking Mushrooms and the Teddy Bear That Knows Your Kinks

Robot wolves are now being used to scare bears away from Japanese schools, scientists have grown mini Neanderthal brains and plugged them into little robots, and snakes are quietly topping the lethality leaderboard while everyone keeps blaming sharks. This week, Will and Rod bounce between wildlife deterrence, prehistoric brain tech, and a public health reality check that hits harder than any movie monster.

We start in Japan, where bears have been wandering into supermarkets and school grounds, and the solution is peak Japan: “monster robot wolves” with sensors, lights, and loud noises designed to scare bears off without harming them. They look like an 80s horror prop, but the goal is serious, keep people safe and avoid lethal control.

Then we head into the lab, where researchers have grown tiny Neanderthal brain organoids, nicknamed Neanderoids, and connected them to small crab like robots. It is fascinating, slightly unsettling, and a reminder that science will always find a way to make the past feel uncomfortably present.

Finally, we look at snakes as one of the world’s biggest killers, with India carrying a huge share of snakebite deaths, and we end with a cybersecurity story where a pen tester talked IT into handing over access on a phone call. Not ideal.
