When 0 = 1000

Why does one of the most familiar numbers on a nutrition label turn out to be far more complicated than it looks? What can a can of fizzy drink teach us about thermodynamics, human metabolism, and the strange ways scientists measure energy? Professor Hannah Fry and VSauce’s Michael Stevens dive into the weird science of calories. From century-old experiments involving fire, body heat, and human digestion to the hidden quirks of modern food labelling. Do “negative calorie” foods really exist? Where does burned fat actually go? Why chewing matters more than you’d think, and how your body is constantly leaking energy out into the universe. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

The Bad Show

With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us. Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?

Hantavirus explained: how does it spread and who is most at risk?

Three people have died after an outbreak of hantavirus onboard a cruise ship travelling from Argentina to Cape Verde. The World Health Organization says a total of seven cases – two confirmed by laboratory testing and five suspected – have been identified on the cruise ship so far. It is also investigating whether rare human-to-human transmission of the virus could be behind the cases. Madeleine Finlay talks to Prof Jonathan Ball from Liverpool School of Tropical Medicine to find out where the virus comes from, how it is transmitted to humans, and what health agencies will be doing to try to contain it.

Radical Acceptance

Last week, we looked at the hidden beliefs that can leave us feeling stuck in life. This week, in the second part of our conversation with behavioral scientist Dave Evans, we talk about radical acceptance. Dave shares why accepting reality as it is can be so difficult — and why it's an essential first step in building a meaningful life. Then, in the latest installment of Your Questions Answered, psychologist Sarah Schnitker returns to answer listeners' questions about patience. When something terrible happens in your life, are you destined to fall apart? In our latest YouTube video, we explore decades of research about how humans respond to grief, loss, and tragedy.

The Secret of Charisma

Charismatic leaders can inspire devotion and give people a powerful sense of meaning. They can also make us vulnerable. This week, we explore how figures across history have gained followers by offering clarity in moments of uncertainty — and why that clarity can come at a cost. Historian Molly Worthen explains how to recognize the spell of charisma, and why questioning it is essential to a healthy society. Then, on Your Questions Answered, Antonio Pascual-Leone returns to respond to listeners' thoughts and questions about moving on after a breakup. Do you have personal stories about being drawn in by a charismatic leader? A question about how we can be swept up in the spell of a mesmerizing person? If you’d be willing to share your question or story with the Hidden Brain audience, please record a voice memo on your phone. Then, email the file to us at feedback@hiddenbrain.org. Use the subject line “charisma.” Thanks! Our next stops on Hidden Brain's live tour are coming up in just a few weeks! Join Shankar in Philadelphia on March 21 or in New York City on March 25. More info and tickets are at hiddenbrain.org/tour. Episode illustration by Imhaf Maulana for Unsplash+ Hosted by Simplecast, an AdsWizz company.

Where did Earth’s water come from?

Here's a conundrum that has captivated scientists: when Earth formed 4.5 billion years ago, our planet was essentially a ball of molten rock. Any water that might have been present during the planet's formation would surely have boiled away immediately. Yet today, water covers about 70% of Earth's surface. So where did all this water come from? And more intriguingly, when did it arrive? Listener Bill in the USA wants to know, and Presenter Caroline Steel is after answers. Assistant Professor Muhammad Abdul Latif is an early earth physicist at United Arab Emirates University. He explains how his modelling has helped us to understand when water first appeared in our universe. The early earth was not a water-friendly place - a hellscape of molten rock, volcanic eruptions and constant bombardments from comets and asteroids, with high levels of solar radiation. These conditions would have evaporated the water. And according to Professor Richard Greenwood at Open University, our earth’s molten iron core would have been a ball of rust if there had been water in the proto-earth mix. So if the water hasn’t always been here, where did it come from? At the Natural History Museum in London, Professor Sara Russell has been comparing the isotopic "fingerprint" of Earth's water with water found in the asteroid Bennu, captured and brought back by the recent Osiris Rex NASA mission. It’s a good match for earth’s water, but could it really be the answer to our question?
