Standing on your own two feet isn’t easy. While many animals can momentarily balance on their hind legs, we’re the only critters, besides birds, for whom bipedalism is completely normal. Find out why, even though other animals are faster, we’re champions at getting around. Could it be that our upright stance made us human? Plus, why arches help sti…
 
Two heads may be better than one. But what about three or more? A new study shows that chimpanzees excel at complex tasks when they work in groups, and their accumulated knowledge can even be passed from one generation to the next. But group-think also can be maladaptive. When humans rely on knowledge that they assume other people possess, they can…

Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end. We c…
 
The Earth is not round. Technically, it’s an oblate spheroid. But for some people, the first statement is not even approximately correct. Flat Earthers believe that our planet resembles – not a slightly squashed grapefruit – but a thick pancake. A journalist who covered a Flat Earth convention describes the rationale behind this ever-more popular b…
 
Waste Not Why create more landfill? Perhaps you should resist the urge to toss those old sneakers, the broken ceiling fan, or last year’s smart phone. Instead, repurpose them!

We all get defensive sometimes. For some animals, evolution has provided a highly effective mechanism for saying “back off!”. A puncture by a pair of venom-filled fangs gets the point across nicely. But one animal’s poison may be another’s cure. Some dangerous critters churn out compounds that can be synthesized into life-saving drugs. Meet the spi…
 
The Earth’s surface is dappled with more than a thousand volcanoes. They mark the edges of tectonic plates, spewing hot gas and ash, and boiling over with lava. We can detect the warning signs of an eruption, but why is it still so hard to predict? Meet a few currently active hot heads: Mauna Loa, Nyiragongo, Fagradalsfjall, and Soufrière – and fin…
 
Can self-deception be useful? During the pandemic, it has been fashionable to say that we’re “following the science,” and that our behavior is determined by verifiable facts. We are, after all, self-declared rational beings, and that’s clearly useful in guiding our reaction to a pandemic. It’s true that fear and suspicion have caused some to make c…
 
Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they li…
 
They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome. We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment. Henrietta Leavi…

Find out why color perception is a trick of the brain, and why you and I may not see the same shade of green. Or blue. Or red. Also, platypuses and the growing club o…

Okay you animals, line up: stoned sloths, playful pandas, baleful bovines, and vile vultures. We’ve got you guys pegged, thanks to central casting. Or do we? Our often simplistic view of animals ignores their remarkable adaptive abilities. Stumbly sloths are in fact remarkably agile and a vulture’s tricks for thermoregulation can’t be found in an o…

Find out why multiple strains of microbes, engaged in a delicate ballet with your T-cells, join internal fungi in combatting disease. Plus, global ecosystems also depend on the diversi…
 
Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society. We w…
 
One of the many shocking aspects of the Capitol attack was that it revealed how thoroughly the nation had cleaved into alternate realities. How did we get to this point?

Psychics may not be able to predict the future or sense your thoughts. Nonetheless, they rake in hundreds of millions of dollars every year.

Find out what alarming discovery led one naturopath to quit her practice…

Also talk of VPR Stassi's baby name at the end because how could we not? Hartford Charlie Rose!!!! A mess! Learn more about your ad choices. Visit megaphone.fm/adchoices…

The old ideas about cultural collapse are yielding to new ones based on careful investigation on the ground - but also from above. What surprising explanations have we found and are we off base to think that ancient societies suc…
 
The reign of Le Grand K has come to an end. After 130 years, this hunk of metal sitting in a Parisian vault will no longer define the kilogram. The new kilogram mass will be defined by Planck’s constant, joining three other units for redefinition by fundamental constants. But as we measure with increasing precision – from cesium atomic clocks to gr…
