As news breaks that archaeologists have found the tomb of St Nick in Turkey, we check in on the North Pole Father Christmas, and fact-check his present giving schedule with advanced level physics and a Gant chart.

Plus, prepare for stories of reindeers high... despite their apparent immunity to their favourite hallucinogenic mushroom treats. And we burrow into Santa’s iconic beard to find any microbial magic that lives there.

And yet more reindeer magic, this time the mysteries of their amazing body clocks, which they seem to be able to switch on and off at will... AND we reveal Rudolf the red nose reindeer’s big secret. You’ll never hear that song in the same way again

Presenter: Marnie Chesterton, with Phillys Mwatee and Camilla Mota Producers: Emily Knight, Alice Lipscombe-Southwell and William Hornbrook Sound engineer: Searle Whittney

Towana Looney became the first living person in the world to get a kidney from a new kind of genetically modified pig last month. Health correspondent Rob Stein got exclusive access to be in the operating room.

Towana is a 53-year-old grandmother from Gadsden, Ala. She's been on dialysis for four hours a day, three days a week since 2016. Her immune system would reject a human kidney. So the Food and Drug Administration made an exception to its usual clinical study requirements to allow Looney this new kind of pig kidney. But the procedure is controversial.

New insights into how our skin learns to tolerate and co-exist with bacteria on its surface show great potential for the development of simpler and less invasive vaccines. Stanford University’s Djenet Bousbaine has published two papers in Nature detailing the microbiological research and mouse vaccination experiments that could change the future of immunisation. The Sun is the hardest place in the Solar System to reach. But by the time the next edition of Science in Action is on air, NASA’s Parker Solar Probe will have swooped through the scorching corona layer of the Sun, re-emerged, and be readying itself to relay the details of magnetic fields and particle storms to the team. NASA Helioscience deputy manager, Nicky Rayl, reveals all about the mission and explains why the Parker Probe’s future looks bright. And a trip half a billion years back - and then some - to the dawn of complex life here on Earth. Microfossil hunter Shuhai Xiao, from Virginia Polytechnic Institute and State University, has been compiling a single statistical database to better understand evolution during the so-called ‘boring billion’, why subsequent changes on the planet triggered a new diversity of species to emerge, and how the interplay between biology and geology has paved the way for modern life as we know it.

Old mines leave behind a a pressing problem: Huge holes that make the landscape look like a chunk of swiss cheese. But in Germany, some scientists and city planners are turning these into lakes.

The largest one will be the biggest artificial lake in Germany when it's done, with a shoreline of 26 kilometers or about 16 miles all around.

But it's not as easy as simply filling the holes with water. It takes a LOT of research to get this science right.

AI uses a lot of power. Some of the next generation data centers may use as much power as one million U.S. households. Technology companies like Microsoft, Google, Amazon and Meta hope nuclear power will offer a climate solution for this energy use. Nuclear power plants can deliver hundreds of megawatts of power without producing greenhouse gas emissions. But some long-time watchers of the nuclear industry are skeptical that it's the right investment for big tech companies to make.

Racism is often covered as a political, cultural, or news story. But how is it affecting people's health? That's the question Cara Anthony, a KFF News reporter, wanted to answer: not just on an individual scale, but on a community-wide one. So for the past few years, she's been reporting on a small town in the Midwest that illustrates that health issue: Sikeston, Missouri. Today on the show, Cara walks host Emily Kwong through Sikeston's history — and what locals and medical experts have to say about how that history continues to shape the present.

For more of Cara's reporting, you can check out KFF Health News' documentary and four-part podcast series, Silence in Sikeston.

The federal government has been tracking the weather for more than 150 years. Yet over the last few decades, the rise of the Internet and big tech have made weather forecasting a more crowded space. Today, our colleagues at NPR's daily economics podcast The Indicator report on the value of an accurate forecast and the debate over who should control weather data.

It seems bizarre to seek out experiences that are uncomfortable or downright painful. Yet examples abound: it’s common to eat painfully hot chillies, drink bitter coffee, or ‘feel the burn' when exercising - and enjoy it. CrowdScience listener Sandy is baffled by this seemingly counterintuitive phenomenon, and has asked us to investigate. Presenter Anand Jagatia turns guinea pig as he tests a variety of unpleasant sensations, and unpicks the reasons we’re sometimes attracted to them. He meets chilli-eating champion Shahina Waseem, who puts Anand’s own attraction to spicy food to the test. Food scientist John Hayes explains how our taste receptors work and why our genes affect the appeal of bitter food. Neuroscientist Soo Ahn Lee describes her research looking at what happens in participants’ brains when they eat chocolate and capsaicin, the chemical that makes chillies hot. As for the ‘pleasurable pain’ we sometimes experience when exercising, sports doctor Robin Chatterjee reveals the secrets of the ‘runner’s high’, while neuroscientist Siri Leknes explains why the feeling that something’s good for us can make discomfort pleasurable.

This week, a banana sold at auction for $6.2 million dollars. Well, not quite… it’s actually a piece of conceptual art and it’s WAY more than just a banana. There’s also some duct tape. In response to this most bananas of auctions, the Unexpected Elements team are going bananas for bananas! We investigate the science of slipping on a banana-skin. Is it just ‘cartoon physics’ or are they actually a slip-hazard? And did you know your breakfast banana might be… radioactive? Also, can Romanian ethical hackers succeed where the police have failed? We look at the computer sleuths tackling real life missing persons cases. We find the answer to why toads have evolved such dangerous skins, and yet more bananas, as we look at the pros and cons of the Ethiopian False Banana. Why hasn’t this hardy plant conquered the world?

In the 1950s, scientists exposed a tin of meat to a dose of radiation that they expected would kill all forms of life. But one organism defied the odds and lived: Conan The Bacterium. Turns out this microorganism, known to science as Deinococcus radiodurans, is capable of surviving extreme levels of radiation — thousands of times the amount that would kill a human. So what's Conan's secret?
