About 66 million years ago an asteroid at least 6 miles wide crashed into the Earth, in the shallow sea that is now the Yucatan Peninsular in Mexico. It gouged the Chicxulub crater 18 miles deep; threw 25 trillion tonnes of debris into the atmosphere, much of which was hotter than the Sun, created huge seismic waves and massive tsunamis churning the Gulf of Mexico, tearing up coastlines and peeling up 100’s of metres of rock. 75% of the Earth’s forest burned. Debris was thrown out across the Solar System and North America was showered by a fan of glassy molten rock droplets. This geological event marked the end of the Cretaceous period and the start of the Palaeogene. Most people accept that this massive event caused the last great extinction, the end of the dinosaurs and a period of intense cold. Many fossil finds back this theory up. But very little fossil evidence showing the impact of the actual event has been found. Until now. Hundreds of miles from Chicxulub in a fossil site called Tanis, in North Dakota, part of the vast Hell Creek formation, is a fossil find that depicts the turmoil 10's of minutes after the asteroid hit. Marine and freshwater fish are found tangled together with these glassy droplets crammed in their gills, Charred trees are mixed up with hundreds of mangled animal bones, amber perfectly preserving drops of what was molten Earth. It's got palaeontologists including Professor Phil Manning at Manchester University very excited.

The gravitational wave detectors LIGO and VIRGO have been recently upgraded and made more sensitive to the miniscule signals that denote ripples in gravity - gravitational waves. Professor Sheila Rowan of the University of Glasgow explains to Gareth Mitchell that she hopes that with this third run of the detectors, they will be finding not just one or two signals that provide evidence of massive events in our universe, but hundreds, maybe even thousands.

In the quest to understand how corals are affected by rising sea temperatures we need to understand the symbiotic relationship they have with dinoflagellates, the single-celled algae that live in, and use photosynthesis to make food for the coral. When coral gets too hot and undergoes 'bleaching', this is the algae leaving the coral. Yixian Zheng at the Carnegie Institution of Washington takes Roland Pease on a tour of her coral tanks and explains that she's hunting for a model coral organism to study this process at the genetic and molecular level.

A crime has been committed in the studio. Gareth's tea has been drunk and his biscuits have been nibbled. Luckily evidence was left at the scene of the crime - a shoeprint with distinctive wear patterns. One quick phone call and the director of the Leverhulme Research Centre for Forensic Science at the University of Dundee, Professor Niamh Nic Daeid is on the case. She's asking the public to help build up a database of footwear prints. The project is the largest ever study into the variation in footwear marks made by the same shoes across different surfaces and activities so that the variation observed can be used to explore links between the shoe and the mark it makes. In order to do this, she's asking thousands of individuals to take part in a large-scale citizen science project by taking pictures of their footwear and the marks they make. This will help the Dundee team build a substantial database for use in their research to aid the scientific validation of footwear marks as evidence for use in the criminal justice system.

Board Game Science

Board Game Science

It’s that time of the year when many of us are at home with friends and family, losing track of time, eating leftovers, and, of course, playing games. This festive season, we look at the science of games and, of course, play some ourselves. It’s presenter Marnie Chesterton versus producer Florian Bohr at Marnie's kitchen table.... Who will win the Inside Science games special?Irving Finkel from the British Museum tells Marnie about the Royal Game of Ur, one of the most ancient board games which is strikingly similar to more modern examples of race games. Also, why we play games with author and neuroscientist Kelly Clancy, and why we struggle to comprehend the randomness of dice with author Tim Clare. To finish it off, mathematician Marcus du Sautory explains the geometry behind the game Dobble and leaves listeners with a Christmas puzzle: Can you figure out the symbols on the two missing Dobble cards?

Fact-checking the Bovaer backlash

Fact-checking the Bovaer backlash

Some social media users have been pouring milk down the drain and chucking their butter in the bin in protest over a new additive in cow feed that claims to reduce methane emissions. The online posts, attacking Arla Food’s trial of Bovaer with three big supermarkets and 30 farms in the UK, have had millions of views. So, what do we know – what is this additive and how is it going to tackle burpy cows? And what is the evidence it is safe? We interrogate the science with Sharon Huws, professor in animal science, and food scientist Dr Stuart Farrimond... Also this week, are billionaires really deserting Earth for space? What is the upshot for our plastic waste problem after global talks on a treaty ended in failure? And why, just why, are orcas being spotted wearing salmon hats?

Is flood forecasting failing?

Is flood forecasting failing?

The south Wales town of Pontypridd saw cars submerged, people bailing floodwater out of their homes using bins, and the beautiful park and lido transformed into a brown mess, as parts of the UK were flooded. But, it's nothing new. Pontypridd was severely flooded just four and a half years ago – and these are scenes that play out around the UK every winter. So, is the way we warn people about floods failing? We’re going to unpick exactly how floods are forecast – and what went wrong – with natural hazards researcher and hydrologist, Professor Hannah Cloke. Also this week, sharing your microbiome with friends, alternative plastics, and was the most recent climate summit good COP or bad COP?

Nuclear medicine shortages and Jane Goodall on COP29

Nuclear medicine shortages and Jane Goodall on COP29

A shortage of medical isotopes used to detect cancer has experts concerned that the shortfall could be delaying diagnosis and could even be costing lives. Exactly what these nuclear medicines are and how they are made is key to understanding the national scarcity. So, we’re going back to basics and learning all about medical isotopes. We also speak to world-famous conservationist and primatologist Jane Goodall who, now aged 90, continues to travel the globe campaigning to protect the natural world. Dame Goodall reflects on a life of studying our closest living animal relatives, chimpanzees, and as COP29 gets under way, speaks about the “closing window of time” to turn the tide on climate change and nature loss. Also this week, we answer the listener question “Why don’t we just throw nuclear waste into volcanoes?” and can Marnie spot AI vs real poetry?
