Women have evolved over hundreds of thousands of years to have more sensitive noses, sharper hearing at high frequencies, and longer life expectancy than men. But why have women's bodies been so under-researched? It’s one of the many questions Cat Bohannon raises in her book Eve: How the Female Body Drove 200 Million Years of Human Evolution.

Shortlisted for the Royal Society Trivedi Science Book Prize, Eve explores how women’s biology has shaped human history and culture. In the lead up to the winner’s announcement, New Scientist books editor Alison Flood meets all six of the shortlisted authors.

In this conversation, we hear what motivated Cat to spend more than a decade researching and writing the book, how understanding the evolution of female traits can give us deeper insights into the workings of our species, and the overlap between sexism and science.

The winner of the Royal Society Trivedi Science Book Prize will be announced on the 24th October. You can view all of the shortlisted entries here:

Why We Die is a book about ageing and death, written by Nobel Prize-winning biologist and former president of the Royal Society, Venki Ramakrishnan.

Venki is on the shortlist for the Royal Society Trivedi Science Book Prize. In the lead up to the winner’s announcement, New Scientist books editor Alison Flood meets all six of the shortlisted authors.

In this conversation, Venki explores humankind’s unique ability to understand and contemplate our own mortality, why some animals live such short lives and others for hundreds of years, if ageing is simply an inevitable and evolutionary practical part of life and whether emerging technologies will make it possible for us to life forever - if that’s really what we want.

Episode 269

Could we re-freeze the Arctic… and should we? The Arctic is losing ice at an alarming rate and it’s too late to save it by cutting emissions alone. Geoengineering may be our only hope. A company called Real Ice has successfully tested a plan to artificially keep the region cold - but what are the consequences and will it work on the scale we need?

Octopuses and fish have been found hunting together in packs in an unexpected display of cooperation. Not only do the fish scout out potential prey, they even signal to the octopuses to move in for the kill. And a fish doesn’t prove helpful? They get punched.

The world’s oldest cheese has been found in China - and it’s 3,500 years old. As we get a fascinating look into the fermenting habits of ancient humans, find out how modern day fermentation is being repurposed to help us create biofuels, break down microplastics and more. We hear from Tom Ellis, professor of synthetic genome engineering at Imperial College London.

Our bodies are littered with microplastics - they’re in our livers, kidneys, guts and even our olfactory bulb. How worried should we be? Microplastics have been linked to some pretty serious health consequences - but are they the cause?

Hosts Rowan Hooper and Sophie Bushwick discuss with guests Madeleine Cuff, Michael Le Page and Grace Wade.

Episode 268

Research has long linked loneliness to surprising health conditions, including diabetes and some cancers. The assumption has been that loneliness in some way causes these issues, perhaps through increased stress or inflammation. But in a study of tens of thousands of people’s biomedical data, that link has gotten more complicated. Where does this leave the relationship between loneliness and health, and the public health programs that are trying to tackle both?

Supermassive black holes are so big and existed so early in the universe’s history that astronomers are unsure how they formed. Dark matter to the rescue? Among the theories of how they formed is “direct collapse,” which a study finds may be possible with some help from decaying dark matter. But a specific type of dark matter is needed to make this theory work…so what’s next?

A photon has been observed travelling in negative time. It was caught leaving a cloud of atoms before it ever entered it. How is this possible? Is this a time travelling photon? Well, somehow, no laws of physics were broken. Obviously some quirky quantum effects are in play – but what exactly is going on?

Plus: How Earth may have once had a ring around it; a pair of black hole jets that are 23 million light years across; how some long-stemmed flowers have evolved to help bats pollinate them; and the discovery of a brand new, teeny tiny chameleon.

Hosts Timothy Revell and Christie Taylor discuss with guests Leah Crane, Sophie Bushwick and Karmela Padavic-Callaghan.

Episode 267

The remains of an ancient Neanderthal man discovered in France may be one of the last members of a lost line. Researchers analysing the DNA of the fossil nicknamed “Thorin” (named after the dwarven king in the Hobbit) made the surprising discovery that he’s possibly one of the last of his line. He may have been part of a group that lived in isolation for 50,000 years.

How can we tell climate change is to blame for specific heat waves, hurricanes, or other extreme weather events the planet has been hit by in recent years? That’s where attribution science comes in. Find out how the fingerprints of climate change could one day make it into your daily weather report.

Elephants, chimps and even chickens have shown signs of self-awareness. Even a fish, the cleaner wrasse, has passed the famous ‘mirror test’ in recent years. But new research on this territorial fish has found it can also use mirrors as a tool – to decide if they’re big enough to fight another wrasse. Learn more about how cleaner wrasse size themselves up before picking fights, and what this may say about their cognition.

Private astronauts on a SpaceX mission performed the first ever civilian spacewalk on Thursday. Hear reaction to the historic news and why their state-of-the-art spacesuits are grabbing people’s attention. Plus hear how researchers have created a “cloud atlas”, full of gorgeous pictures of the weird and wonderful – and informative – clouds that fill Mars’ sky.

Reporter James Woodford recently took control of one of the most advanced humanoid robots ever created. An energy company is helping NASA test a robot from its Valkyrie programme in Perth, Australia. James met the robot, nicknamed Val, and even helped use virtual reality tools to control her movements.

Hosts Rowan Hooper and Christie Taylor discuss with guests Alison George, Madeleine Cuff, Corryn Wetzel and James Woodford.

Have you ever heard a haddock knock? What about a cusk eel’s chatter?

Sound travels four-and-a-half times faster through water than air and can be heard across huge distances. It’s how whales are able to communicate hundreds of kilometres apart. Yet, for all its wonder, much of the underwater acoustic world remains a mystery to scientists.

Although human ears can’t detect most marine sounds, the invention of hydrophones – microphones designed to capture underwater audio – is helping scientists begin to unravel this hidden world.

So how does sound move through water? And how do underwater creatures perceive and use sound? Amorina Kingdon’s new book ‘Sing Like Fish’ explores these questions, revealing how marine life depends on ingenious uses of sound to communicate, navigate, and thrive.

In this episode, Kingdon and host Christie Taylor explore the fascinating ways fish and other marine animals produce sound, the physics of underwater ears, and how humans are impacting critical underwater soundscapes. Plus, samples of some of the most captivating underwater sounds she’s encountered in her research.
