Do our genes control how we respond to COVID? The question has been nagging at the world since the pandemic began. Now we have the answer - and it's yes. In this programme, geneticist Nathan Pearson uncovers the specific bits of DNA that make you more likely to catch coronavirus, as well as the bits that might make you sicker.... Like this podcast?

How do we cope at the extremes of low temperature? Across the world, groups of people have historically made their home in icy and inhospitable landscapes... and even today, groups of thrill seekers push their bodies to the limits by going swimming in water close to freezing. In this month's programme, genes that help us handle - and even enjoy - being very cold. We've got two stories from the ancient ice, including the oldest ever DNA; plus, two modern genes found to be helping us out in...

Meet the small DNA differences that make their mark by existing in the magical period of early development. We'll hear how mutations in the very first stages of human embryos have bizarre consequences for identical twins; and how even earlier in the process, sperm use selfish genes to get ahead of the competition.

This week, a message from Naked Scientists listener Loretta. "I'm curious if your show might cover some of the most interesting case studies of organisms developing tolerance to severe toxins, what genetic insight this gives us about adaptation and natural selection more broadly, and what some of the tradeoffs might be when evolving to have such tolerances." We're answering her question: how do animals - and even humans - eat poison, and get away with it? Like this podcast? Please help us by...

The same thing that makes the patchwork colours on a tortoiseshell cat, also - according to some - is why human females live longer, see colour better, and even more often survive the coronavirus. It's all thanks to having two X chromosomes. Females compensate by switching one of them off, and the result is two distinct groups of cells in the body, each preferring one of the two X's. Welcome to the weird world of female mosaicism... Like this podcast? Please help us by supporting the Naked...

Are you one of the many people who take ACE inhibitors or ARBs to treat high blood pressure? Or to help with heart issues or diabetes? In the UK, this is about one in seven people, making these are some of the most common prescription drugs out there; and recently there have been worries that they might make a coronavirus infection worse. The link between the drugs and the virus is a molecule inside everyone's bodies called ACE2. On today's show, meet ACE2, the protein in the spotlight: the...

Listener Vivek got in touch with a question about a rare genetic disease his son has, called FOXG1 Syndrone. In fact, it's so rare - and so newly-discovered - that only about six hundred people in the world have been diagnosed. Kids with FOXG1 have severe developmental delays; in Vivek's words, "everything that can go wrong - it's gone wrong with him." But the parents of FOXG1 children have been unusually tenacious when it comes to shaping the course of science. In this programme we meet...

There are very few African studies in genetics. Most of the existing data are based on Europeans. This is why a number of institutions have collaborated to survey thousands of people's genomes in rural Uganda.

Half a million genomes. That's how many the UK Biobank has, stored as blood samples in freezers up in Manchester. And in September 2019 they announced a project to sequence every single one of them. It's the obvious next step for the UK Biobank, the research study that began in 2006 and now consists of an enormous biological database: the personal and medical information of its 500,000 volunteers. That data is available to any researcher who applies to use it. But how is this, the biggest...

It's a doggy dog world... in this episode we're talking pugs, bulldogs, and French bulldogs. They've all been bred for flat faces, but their airways haven't shrunk alongside their skulls - meaning that they often struggle to breathe. How has this happened? After evolving for millions of years, why are their airways literally too big to fit into their heads? Have they been betrayed by their own genes? Naked Genetics is on the case.

Naked Genetics is back with new episodes every month! Today we're taking a step back. Where does genetics actually come from? How did we get to today's world of genome sequences and gene editing? It all started with an 19th-Century monk, working in his garden - but who was he really, and how did it take thirty years for him to be recognised? If you think you know this story, you might be surprised.
