Drink driving is one of the biggest killers on our roads. Brian Suffoletto is an A&E doctor in the US where he's spent the past 15 years developing digital interventions to stop people drinking and driving. Lately he's been working on a system that uses a smartphone to analyse the way a person walks to pick up on subtle giveaways that they're over the limit. Katie Haylor heard how it works...

PTSD is a disease that may occur after experiencing trauma, often characterised by the involuntary reliving of particularly painful memories. About 1 in 3 people who experience trauma will develop PTSD, but it's unclear why some people develop it and others don't. New research out of the University of Basel has shown that a genetic component may help explain why some people are more susceptible, as researcher Dominique de Quervain told Eva Higginbotham...

Dr Chris Smith joins Radio New Zealand National's Kim Hill to talk about the latest news and breakthroughs around the Covid-19 coronavirus. How the virus spreads, the prospect of long-term immunity following natural infection or vaccination, how herd immunity works, what drugs do and do not look promising for Covid-19 patients, and how to stay safe on the bus...

Getting cold won't just make your hair stand up, it may also make it grow. Yulia Shwartz at Harvard University and her colleagues have found that the nerves that give us goose pimples also send a message to the cells in the follicles that produce hairs, making them grow. It explains the prolific winter coat that some animals grow in the cold. Cambridge dermatologist Jane Sterling took Chris Smith through the findings... Like this podcast?

Giant pandas, which for decades were endangered, finally shed the status in 2016 thanks to huge conservation efforts. But scientists have been warning that their reserves aren't well designed for the ecosystem as a whole - and now a group of zoologists have found that even though panda numbers have gone up since the 60s, big carnivores like leopards have almost disappeared. Bill McShea from the Smithsonian Conservation Biology Institute is one of the authors of the study, and he told Phil Sansom what's been going on inside the panda parks... Like this podcast?

New research means we're going to have to think again about how human sperm swim. You might have seen movies of them looking a bit like tadpoles in a pond - the head carries the male's DNA and the long tail, or flagellum, propels the sperm forward. That motion was first described over 300 years ago, but now a joint team from Britain and Mexico think we might need to re-write the textbooks, as Eva Higginbotham heard from Hermes Gadelha...

The world took a step towards our goal of harnessing nuclear fusion as an energy source last week when the construction officially began of ITER, the new International Thermonuclear Experimental fusion Reactor. Michel Claessens is the author of the book ITER: The Giant Fusion Reactor. He spoke to Adam Murphy about the project... Like this podcast? Please help us by supporting the Naked Scientists

In early August, the UK stepped back from some of the proposed lockdown easing measures. So how are public health officials managing these situations, are we in good shape to cope with the approaching winter, and is this the pattern of coronavirus cases we should expect going forward? Chris Smith hears from Maggie Rae, president of the faculty of Public Health.... Like this podcast? Please help us by supporting the Naked Scientists

The millions of rods and cones in the retina at the back of each of your eyes, which turn light into nerve signals to send to the brain, use a lot of energy. So the retina tends to burn out faster than the rest of the body. But now scientists have found that short bursts of a red light shone into your eyes could help reduce or even reverse this ageing process. Katie Haylor spoke to Glenn Jeffery, who's been looking at a group of 24 people with no eye disease for the study... Like this podcast? Please help us by supporting the Naked Scientists

The liver is an incredible organ that does a number of different jobs - including cleaning our blood and breaking down chemicals and drugs - to keep us healthy. And liver problems can have serious consequences, resulting in potentially needing a new one in the case of liver failure. And there aren't exactly loads of spare healthy livers around, and some people just aren't suited for transplant. But this week, scientists have published news of an artificial liver system that cleans the blood, and returns it again to the body within a matter of hours, whilst also encouraging the liver tissue to...

Colourful still life paintings of bowls of fruit have been a favourite of artists for generations, and there are thousands of examples in art galleries across the world. Now, two friends from Belgium - one an art historian, and the other a plant biologist - are asking for your help to find paintings that reveal clues about how some of our modern foods came into being. This unusual project came about when the two of them were on holiday in St Petersburg, and visited a museum - as Ive de Smet told Katie Haylor... Like this podcast?

After 22 years of searching, researchers at the Radboud University Medical Centre in the Netherlands have successfully identified the genetic cause behind a certain type of inherited adult hearing loss - a defect in the so-called RIPOR2 gene. Eva Higginbotham spoke to geneticist Hannie Kremer and ear nose and throat surgeon Ronald Pennings about how they did it. Like this podcast? Please help us by supporting the Naked Scientists

Kim Hill catches up with virologist Chris Smith to review the Covid-19 current state of play, from Leicester's lockdown, the WHO stance on masks and aerosol spread, to long-term immunity and long-haul symptoms of Covid-19, the link between ethnicity and more severe Covid-19 disease, and whether the world's over-reacted to the coronavirus threat...

How has the pandemic affected the global food supply? That's the subject of a recent report by the UN's Food and Agriculture Organisation. Their message is that while there have been a few industry issues so far - overripe fruit left unpicked, spoiled batches of milk left undelivered - that's only a taste of what's to come if there's a huge global recession around the corner. Chris Smith and spoke to Maximo Torero - the organisation's chief economist - as well as University of Cambridge land economist Shailaja Fennell... Like this podcast?

Do you consider yourself something of a Dr Doolittle? According to new research from the University of Amsterdam, we're all actually pretty good at understanding what animals are trying to express - at least, animals that we are closely related to like chimpanzees.

Astronomers have taken what might be the first ever picture of a baby planet being formed. It looks like a beautiful tornado-shaped spiral of light, and there's a tiny twist visible inside one of the arms of the spiral. Why is this an achievement? And how can you actually tell whether there's a planet inside that tiny point of light? Phil Sansom asked Anthony Boccaletti, who led the team from the European Southern Observatory in taking this picture - as well as University of Cambridge astronomer Carolin Crawford...

You might think that when you're choosing a partner to have children with that your decision is entirely yours. However it turns out that biology has an interesting trick up its sleeve, which may surprise you. It turns out that there are guidance mechanisms that, like homing beacons, can help swimming sperm get to the eggs. It's because cells in women's bodies release special attracting chemicals into the fluid surrounding the eggs, and, according to a recent paper, these chemicals seem to prefer some sperm over others, taking the decision making completely out of your hands! In reproductive... Like this podcast? Please help us by supporting the Naked Scientists

Everyday in the UK over 40 people die from liver disease, some of whom could be saved by having a liver transplant - but there aren't enough donor livers to go around. But what if we could grow livers in a laboratory, and use those instead? A team in Pittsburgh has now done just that in rats. The livers were transplanted into animals genetically modified to prevent them from rejecting the transplant. Eva Higginbotham heard from Alejandro Soto-Gutierrez how they did it...
