S4E1The Size is the Limit
Jun 2, 20254mCould Godzilla and King Kong, who are bigger than any dinosaur, exist in real life and destroy the world? For Professor Moustache, there is no such thing as a dumb question
S4E2Don’t Sweat It!
Jun 3, 20254mWhy do humans sweat so much and smell so bad, when I smell so good? For Professor Moustache, there is no such thing as a dumb question.
S4E3Baby Boomers
Jun 4, 20254mWhat does “OK boomer” mean? And what’s a boomer anyway? At full gallop on his time pony, Professor Moustache prances into the past to look at how generations are formed and why they never seem to understand one another. It seems psychological biases and the lazy mechanisms of our brains are to blame.
S4E4Coronaviruses
Jun 5, 20254mOh Covid. We were fed up with it at the time and we’ve been confused ever since. Who was to blame again, bats or pangolins? How does a virus travel from animals to humans? Professor Moustache teaches us about the world of coronaviruses. That’s right, Covid-19 is not the only one.
S4E5Babyface
Jun 6, 20254mSometimes when you see a newborn baby, you don’t really know what to say. It doesn’t really look like its parents; it looks more like a crumpled creature. You may think you’re heartless for finding it a little ugly, but Professor Moustache and science are here to explain why! Don’t panic, it’ll get better with time.
S4E6Anger Games
Jun 9, 20254mWe tend to look at whether young people with violent behaviour play video games. But what does the research say? Professor Moustache delves into some pretty dodgy psychological experiments to find out more about the science behind this association.
S4E7Homo Augmentus
Jun 10, 20254mCaptain Hook had a hook as a hand. Darth Vader had bionic limbs. Films make it look easy to replace severed limbs. But is it that easy in real life? What is scientifically possible when it comes to prosthetics? Professor Moustache takes a look at different innovations.
S4E8Furry Insects
Jun 11, 20254mThere are researchers who have not only counted the 3 million tiny hairs found on a moth, but who have also studied how often they clean their fur. If it were up to Nathanaël, we’d put an end to pointless studies like these. Luckily Professor Moustache is there to prove him wrong and show him how the scientists behind this researched ended up helping NASA.
S4E9Skynet, the Artificial Unintelligence
Jun 12, 20254mIf robots in the future developed a conscience, would they want to kill humankind like in “The Terminator”? Let’s imagine for a minute that it was their ultimate goal. Professor Moustache wonders if Skynet could have come up with smarter ways of killing us off, rather than just shooting everyone like in the film.
S4E10Conscious AI
Jun 13, 20254mEveryone is afraid of the singularity – that stage when machines become conscious and inevitably decide to kill us all. Professor Moustache explains that, in order for that to happen, machines would need to develop common sense. And that’s no mean feat when you’re trapped in a robotic body.
S4E11Cry Baby Cry
Jun 16, 20254mScreaming babies anywhere can be unbearable. Especially on trains. Professor Moustache explains that it’s normal to sometimes want to chuck them out the window when they won’t stop crying. Researchers have found that our brains are wired to go nuts when we hear a baby cry. In fact, it’s essential for their survival.
S4E12It’s Not Me, It’s Evolution
Jun 17, 20254mWhy did Mother Nature make babies who won’t let their parents get any sleep? Or who refuse to eat mum’s delicious mashed potatoes? In this episode, a baby goes on trial with evolutionary ethologists at its defense, Professor Moustache as the judge and its parents at their wit’s end.
S4E13Of Machine and Men
Jun 18, 20254mWhy did we feel sorry when that man kicked the cute dog robot? But then we feel nothing when we see a broken blender? Researchers have studied this bizarre human weakness; our tendency to see a soul where there is none. Be careful, you’ll never look at your hoover the same way after watching this episode.
S4E14Plants with Feelings
Jun 19, 20254mWhile mowing the lawn, do you ever think about whether grass or flowers can get hurt when they’re cut? What about whether plants talk to insects? Can Professor Moustache mow the lawn without feeling guilty? Don’t let this be an excuse to miss out on your five a day, but science has shown that the plant kingdom communicates – a lot.
S4E15DIY Poop Survival
Jun 20, 20254mVarious Inuit legends say that in sub-zero temperatures, it’s possible to carve a tool out of a frozen turd. Without any scatological judgment, brave archeologists decided to test it for themselves and fact-check the legend. Professor Moustache explains.
S4E16The Superpower of Spit
Jun 23, 20254mIs it a good idea to use your saliva to clean things? Like a dummy that fell on the floor, or a stain on a table? How about washing Timothée Chalamet’s sandy face in Dune? Scientifically speaking, given the composition of saliva, it’s actually not such a bad idea.
S4E17In Your Face, Santa!
Jun 24, 20254mThankfully there are researchers who ask fundamental questions. Like John Trinkaus, a US professor who wanted to find out whether children really enjoyed having their photo taken with Father Christmas in a local supermarket. Turns out, his methodology was 99 percent statistics and 1 percent psychology.
S4E18Twenty Thousand Eyes Under the Sea
Jun 25, 20254mPeople are afraid of taking airplanes because they fly high and can fall around 11 kilometres. But why aren’t they just as scared on a cruise ship? The boat could also sink 11 kilometres deep. Professor Moustache looks at the science of the deep sea to get a better understanding of his underwater phobia. There is no guarantee he’ll cure it, though.
S4E19Space and Furious
Jun 26, 20254mIf we’re going to live on the Moon, can we bring our good old Fiat 500 with us? Unfortunately, my friends, terrestrial cars are not cut out for lunar weather conditions. We would need to build entirely new automobiles fit for purpose. Luckily, NASA already did.
S4E20Selfish Humans
Jun 27, 20254mProfessor Moustache loves John Trinkaus because he tackled so many everyday mysteries with scientific research. For example, what is the percentage of people who actually respect the ten item limit in the supermarket express lane? Or stop their cars at stop signs? Trinkaus, the ultimate pessimist when it comes to human behaviour, had the answers.
S4E21Crimes Without Gravity
Jun 30, 20254mEvery country has its laws. But what happens when a crime isn’t committed on Earth? What if an astronaut kills a colleague on the International Space Station? And what about on the Moon or Mars? Professor Moustache takes us on an interstellar cruise to explain a few useful treaties and helps us answer these questions.
S4E22An Atomic Blast in Paris
Jul 1, 20254mWhat would happen if an atomic bomb were dropped on Paris? Would those outside the ring highway that surrounds the city make it? According to Professor Moustache, they would, but only if they follow strict instructions given by two Greek researchers on how to survive a blast. Watch out, you’ll have to move quickly…
S4E23Happy as a Tardigrade
Jul 2, 20254mThe tardigrade, an eight-legged micro animal that looks like a teddy bear, can be found everywhere. And Professor Moustache loves them. It may be cute and microscopic, but the tardigrade is extremely resistant! It also only grows at a rate of 3cm per month and uses snails as means of transport.
S4E24Mushroom Zombies
Jul 3, 20254mIn the TV show “The Last of Us”, people become zombies after a fungus takes over their brains, which was inspired by something that happens in real life. There is a fungus that does exactly that to ants. But don’t worry, Professor Moustache is here to reassure you that the human brain is a tad more complicated than that of an insect.
S4E25Monkey Talk
Jul 4, 20254mIf only it were possible for our pets to speak to us and tell us how much they love us… Well, it turns out that scientists have already tried to get monkeys to speak to us using words, signs and symbols. One researcher even managed to recreate the ‘voice’ of a chimpanzee! But would animals actually tell us they love us? Professor Moustache certainly doesn’t think so.
S4E26Researchers with Ants in Their Pants
Jul 7, 20254mImagine you’re a tiny ant in a jungle and you find a massive cookie chunk just three metres from your anthill. You rush to grab a piece of the cookie, but how will you find your way back to your anthill? You’ve walked so many zigzags and your eyesight isn’t exactly the sharpest. Professor Moustache dives into the world of myrmecology, the study of ants, to find an answer.
S4E27Tiny-Arms-Osaurus Rex
Jul 8, 20254mEven though it is a predatory killing machine in many ways, the poor T-Rex has also been a laughing stock because of the size of its arms. Scientists have long wondered why they are so tiny, so Professor Moustache has decided to take a look at their hypotheses.
- S4E28
Doggy Supernose
Jul 9, 20254mProfessor Moustache finds it a little too easy to make fun of dogs he sees online who would do anything for a biscuit. But if humans were to develop the same sense of smell as dogs, we would quickly realise that actually, humans are totally nose-blind. Maybe we are the ones who should be made fun of?
S4E29Anatomy of a Football Fall
Jul 10, 20254mIf there is one sport that science has studied in detail, it’s football. We thought we knew everything there was to know about football players, but then female players came along! And now, researchers are finding surprising differences between the two genders – especially when it comes to behaviour.
S4E30How Can I Grow My Own Meat?
Jul 11, 20254mIt is possible to grow meat in a lab without killing cows, like growing a plant in a pot. Now, Nathanaël dreams of harvesting his steaks along his window sill. But turns out growing meat is more complicated than we think. Who’s here to crush Nathanaël’s dreams? Professor Moustache, of course!
