‘Today I learnt that tigons and ligers are what you get when lions and tigers interbreed?!’ surprised listener Jamz G tells the doctors. ‘What determines whether species can interbreed?’ Geneticist Aoife McLysaght studies molecular evolution. She explains the modern definition of a species, built on ideas from Aristotle, Linnaeus and Darwin: a species is a group of organisms capable of interbreeding to produce fertile offspring. Hybrids – such as ligons and tigers – are usually infertile, becaus...

"What are wormholes and do they really exist?" asks Manlee-Fidel Spence, aged 12. In this exotic episode, the doctors investigate how wormholes would work. Cosmologist Andrew Pontzen explains why wormholes could allow you to travel through time as well as space. And physicist Jim AlKhalili outlines the infinite problems this could generate. When it comes to wormholes and time travel, many science fiction stories have married solid science and successful storytelling, as Jennifer Oullette describ...
Two cold callers feature in this episode. Jennifer Langston from Ontario in Canada sent this message to curiouscases@bbc.co.uk: "My husband has just taken up cold water swimming and he'll swim in temperatures as low as 6 degrees Celsius. I worry that it's too cold for him, but he claims that 'swimming in cold water is good for you', which drives me bonkers. Can you tell us if there is any scientific proof behind this?” Adam takes a trip to his local lido and asks the locals why they get a kick o...
“I suppose a cold is called a cold because we catch it in the winter," writes Alison Evans from St Albans. "But why is it that we get more colds in winter than in the summer?” This week's Cold Case is all about the common cold, a set of symptoms caused by hundreds of different strains of cold and flu viruses. Adam uncovers the stinky history of infectious disease with medical historian Claire Jones. Virologists Jonathan Ball and Wendy Barclay describe how spiky viruses lock on to our cells, but ...
"My question is about something I became aware of at a young age," explains Samantha Richter from Cambridgeshire. "I was sitting on the carpet at school, being read a story by the teacher. My hair felt as though it was standing on end as waves of a tingly sensation washed over my head. I subsequently found certain scenes in films had this effect, when actors were talking softly, or someone was having their hair brushed." "Then, a few years ago, I discovered that there is a name for the tingles, ...

"Why is it so difficult to predict the weather?" asks Isabella Webber, aged 21 from Vienna. "I am sure there are many intelligent meteorologists and it seems rather straight forward to calculate wind speed, look at the clouds, and data from the past to make accurate predictions, but yet it’s not possible." Adam delves into the history of forecasting with author Andrew Blum, beginning with the mystery of a lost hot air balloon full of Arctic explorers. Hannah visits the BBC Weather Centre to talk...

Stephen Fry (no relation) asks Adam and Hannah to investigate the following question: "All my life I have been mildly plagued by the fact that I have a quite appalling ability to remember faces. I cut people I should know well dead in the street, or at least fail to recognise them in a way which must often be hurtful. At a party I can talk to someone for ten minutes and then see them again twenty later and have no idea who they are unless I’ve made an effort to fix some accessory or item of thei...
