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?

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?

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?

As conflicts in the Middle East and Ukraine continue to dominate the news, many Inside Science listeners have been in touch with the same question: What is the carbon footprint of war? How significant is the impact – and is it crass to even talk about it? We’re joined by Benjamin Neimark from Queen Mary University in London. Also this week, we chat to the incoming DG of Europe’s particle-smashing facility Cern, what have we learnt by defrosting an extinct big cat and, the beetle that could ruin Christmas...

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?
