The world’s polar regions are melting. Beneath the ice lurks all kind of microbes, but how much of a threat do they really present? Microbiologist Dr Arwyn Edwards of Aberystwyth University joins us to explore the threat of so-called ‘zombie viruses’ and he explains where the real danger lies.

These days, pretty much every move we make online is tracked in one way or another. Whether it’s through our social media accounts or online shopping habits, algorithms are getting better at painting a picture of who we are and how we think. But why do we let this happen? 
 In this episode we catch up with science broadcaster and writer Timandra Harkness to talk about her new book, Technology is not the Problem. 
 She tells us how various online agencies keep tabs on us, whether we should be worried about it, and why sometimes it can be too hard to resist buying that expensive pair of shoes you keep getting ads for.   Learn more about your ad choices. Visit podcastchoices.com/adchoices

Why we shouldn’t be afraid of personal data collection

Black holes are surely one of the most fascinating and mysterious phenomena in the known Universe. But few people know that the story behind their discovery, and the cast of dogged, often ignored scientists behind it, is just as interesting. 
 In this episode we catch up with the award-winning science writer and long-time BBC Science Focus contributor Marcus Chown. We talk about his new book A Crack in Everything: How black holes came in from the cold and took cosmic centre stage. 
 He takes us through the gripping story that saw black holes go from being a mere mathematical curiosity to one of the most talked about cosmic objects ever observed.   Learn more about your ad choices. Visit podcastchoices.com/adchoices

The story of black holes, with Marcus Chown

We humans are never truly alone. This is because our bodies are colonised by vast numbers of microscopic organisms that can be found living everywhere from the surface of our skin to deep within our guts. 
 Collectively, this population of microbes is known as the human microbiome, and they play a key role in maintaining our health and wellbeing. 
 In this episode we catch up with Dr James Kinross, a colorectal surgeon and researcher based and Imperial College London and author of the new book Dark Matter: The new science of the microbiome. 
 He tells us about the fascinating ways that our microbiomes can impact our brain health, regulate our emotions and if we could ever use them to make an effective love potion.   Learn more about your ad choices. Visit podcastchoices.com/adchoices

The existence of flight in the animal kingdom is something that many of us take for granted. But on closer inspection, it can perhaps be thought of as one of the miracles of nature. 
 In this episode we catch up with the writer Lev Parikian about his book Taking Flight: How animals learned to fly and transformed life on Earth, which was shortlisted for Royal Society Trivedi Science Book Prize. 
 He tells us about how flight has evolved independently in four separate groups of animals, how bats became the only mammals capable of powered flight, and how some birds ended up losing the ability to fly altogether.   Learn more about your ad choices. Visit podcastchoices.com/adchoices
