Everything Is Predictable: How Bayes' Remarkable Theorem Explains the World is a book about an 18th century mathematical rule for working out probability, which shapes many aspects of our modern world. 

Written by science journalist Tom Chivers, the book has made it onto 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, Tom explores the life of Thomas Bayes, the man behind the theorem, and how he had no clue his discovery would have such sweeping implications for humanity. He explains the theorem’s many uses, both in practical settings like disease diagnosis, as well as its ability to explain rational thought and the human brain. And he digs into some of the controversy and surprising conflict that has surrounded Bayes’ theorem over the years.

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:

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.

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.

⚡️ The first human blood stem cells have been created in a lab and successfully turned into functioning bone marrow. This research could revolutionise the treatment of blood cancers like leukaemia and lymphoma. So far it’s only been tested on mice, but researchers are hopeful it could work in humans too.

⚡️ In other mouse news, we are now able to turn mice see-through. Using a surprisingly common food dye, researchers have turned the skin of living mice transparent. The technique, which didn’t harm the mice, offers a new (though gruesome) look into the living body.

⚡️ The US is planning to launch spy balloons to carry out surveillance and act as backup communication links. The news comes just a year after the US shot down a Chinese balloon that was full of intelligence-gathering equipment. Coincidence? Find out why balloons are making a comeback.

⚡ Bats have a huge role in human health, often harbouring diseases that are then passed onto us, such as rabies and covid-19. But it turns out when bat populations collapse, that’s also bad for human health. New research finds that when bats die, insecticide use in agriculture goes up and so does infant mortality – find out how the three are linked.

⚡ How dark is deep space? Are there any regions of the universe that are completely and utterly devoid of all light? Researchers now have an answer. Plus, ISS astronauts report a strange noise on Boeing’s stranded Starliner capsule.

🎙️ Hosts Timothy Revell and Christie Taylor discuss with guests James Woodford, Chris Simms, Jeremy Hsu and Michael Le Page.
