BBC INSİDE SCİENCE

Artificial intelligence is the big talking point of the week, with UK PM Sir Keir Starmer announcing a drive to unleash its full potential.

It’s already being used in healthcare, but recent studies have exposed both strengths and weaknesses.

We’re joined by Dr James Kinross, a surgeon and researcher at Imperial College London, to discuss the positives and the pitfalls.

Also this week, we talk all about what a Trump presidency might mean for science; why powerful winds are driving the deadly fires in LA – and anyone for science-optimised pasta? Marnie is helped by a physicist to make the perfect Cacio e Pepe.

Spoiler alert: Recipe below!

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?

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?

Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene.

The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary.

But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly.

So, what happened?

We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next...

Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.

Guest presented by Liz Bonnin.

As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together entirely in a factory before being shipped out, theoretically, anywhere: are micro modular reactors the future of nuclear energy or too good to be true? Dean of Engineering at the University of Liverpool, Eann Patterson, has just published a paper proposing a fleet of micro modular reactors to bear the burden of our energy load and he joins us to discuss the reality.

What came first, the chicken or the egg? Science writer, broadcaster and now egg expert Jules Howard joins us to answer this age old question. His book Infinite Life tells the story of how the egg propelled evolution – whether it’s bird, insect, or mammal.

Earlier this week, some of the world's leading astrophysicists came together at The Royal Society to question the very nature of our Universe. Does the Lambda Cold Dark Matter model, which explains the evolution of the cosmos and the Big Bang, need a rethink? Dr Chris North, an astrophysicist from the University of Cardiff, joins us in the studio to explain what this model says, and why it might need to be changed.

The last few weeks seem to have been a non-stop cycle of depressing climate stories, with floods in Pakistan, mass coral bleaching and last month being the hottest March ever recorded. It's perhaps no surprise that many people are anxious about the news. Vic Gill is joined by Prof Lorraine Whitmarsh, an environmental psychologist at the University of Bath, and Tom Rivett Carnac, an author, political strategist and co-host of the podcast Outrage + Optimism. Together they discuss climate anxiety, and how to stay engaged with the news without feeling overwhelmed.

And with all this wet weather, how are our precious insects faring? It turns out, bumblebees might have a trick up their fuzzy sleeves when the ground gets flooded - at least according to a new experiment led by Sabrina Rondeau from the University of Ottawa. We also get bumblebee expert Dave Goulson on the line to tell us more about these charismatic insects.
