We've been building computers to think like us for years, but our ability to replicate human senses has been impossible. Until now. This technological revolution is starting to profoundly change not only how we interact with the world around us, but is allowing us to see, hear, smell, taste and even touch things we never imagined possible before.An artificial intelligence revolution is super-charging sensing technology, promising us eyes with laser precision, ears that can distinguish every sound in

James Gallagher get's behind the hype to find out if sperm counts are really falling? There are plenty of headlines telling us they are, but also scientists who disagree - he unpicks the evidence with two of them. James also gets his own sperm sample analysed and meets a couple who found the reason behind their low count was one of the leading causes of male infertility.

2023/06/05

James Gallagher reports on a psychedelic renaissance; a new wave of research testing hallucinogenic drugs like magic mushrooms to treat mental health conditions.There’s genuine excitement and some early encouraging evidence. A manufacturer tells James that in five years’ time, it’s possible that psychedelics could be part of the medicine cabinet – but with the hype, there’s risk too and there’s much still to learn about who these drugs could help and how.Presenter: James Gallagher Producer:

2023/05/29

We are familiar with fungal infections like Thrush and Athlete’s Foot, but fungal diseases that can kill are on the increase. The World Health Organisation is so concerned that it has published its first ever list of life threatening fungi. James Gallagher hears stories of hospitals being shut down, a ruined honeymoon and fungal infections that consume human tissue leaving terrible disfigurement. Add to that The Last of Us, a hit video game turned TV series where a parasitic fungus manipulating the

Soaring food prices mean putting food on the table is a daily struggle. This is the grim reality for millions around the world. But hunger, so long a feature in lower-income countries, is becoming a familiar picture in richer ones too. James Gallagher reports from the UK, one of the wealthiest countries in the world, where food prices are rising at the fastest rate for 45 years and millions are turning to charity to feed themselves and their families. He visits the charities which help people to

After centuries of use in wound-healing, the maggot is back. The rise of the drug-resistant superbug means fresh eyes are focused on the superpowers of the larvae of the greenbottle fly species, Lucilia Sericata. James Gallagher reports on the healthcare professionals who are turning to maggot therapy to help clean up wounds and stop infection. He talks to Melanie who has Type 1 Diabetes and had a quarter of her foot amputated. When the skin around the wound started to die, threatening the whole

James Gallagher is on a mission to find out what is the least amount of exercise you can do to still stay healthy. James goes on a Ramblers wellbeing walk, uses a treadmill for the first time and takes a hot bath all to find out how lazy he can be and still gain some health benefits.(Photo: James Gallagher on a treadmill.

The impossible number

Discovery ·

2023/05/01

There is a bizarre number in maths referred to simply as ‘i’. It appears to break the rules of arithmetic - but turns out to be utterly essential for applications across engineering and physics. We are talking about the square root of -1, which makes no sense.Professor Fry waxes lyrical about the beauty and power of this so-called ‘imaginary’ number to a sceptical Dr Rutherford. Dr Michael Brooks, author of The Maths That Made Us, tells the surprising story of the duelling Italian mathematicians who

The mind-numbing medicine

Discovery ·

2023/04/27

This episode will render you oblivious, conked out and blissfully unaware. It’s about anaesthetics: those potent potions that send you into a deep, deathly sleep. Listener Alicia wants to know how they work, so our sleuths call on the expertise of consultant anaesthetist Dr Fiona Donald. Fiona shares her experience from the clinical frontline, and explains what we do and don’t know about how these chemicals work their mind-numbing magic.We hear about ground-breaking research led by Professor Irene

‘Can we bring back extinct species?’ wonders listener Mikko Campbell. Well, Professor Fry is pretty excited by the prospect of woolly mammoths roaming the Siberian tundra once more. And everyone is impressed with the science that might make it happen. But Dr Rutherford comes out STRONGLY against the whole thing. Can our expert guests win him over?Dr Helen Pilcher shares the tale of Celia the lonely mountain goat, and makes the case for cloning to help protect species at risk of extinction. Professor

The puzzle of the pyramids

2023/04/10

The Great Pyramids of Giza are awesome feats of engineering and precision. So who built them - and how? Was it a mysteriously super-advanced civilization now oddly extinct? Was it even aliens?Nah, course not! Rutherford and Fry investigate how these inspiring monuments were really constructed, and learn about the complex civilisation and efficient bureaucracy that made them possible.Professor Sarah Parcak busts the myth that they were built by slaves. In fact, she reveals, it was gangs of well-paid

Close your eyes and think of a giraffe. Can you see it? I mean, *really* see it - in rich, vivid detail? If not - you aren’t alone!We’ve had scores of messages from listeners who report having a ‘blind mind’s eye’. They don’t see mental images at all and they want to know why. Jude from Perth wants to know what makes her brain different, and Diane from Scotland wonders whether it affectes her ability to remember family holidays.Our sleuths learn that this is a condition recently termed ‘aphantasia’

Tim Lamont is a young scientist making waves. Arriving on the Great Barrier Reef after a mass bleaching event, Tim saw his research plans disappear and was personally devastated by the destruction. But from that event he discovered a novel way to restore coral reefs. Playing the sounds of a healthy coral reef entices fish in to recolonise the wrecked reefs. Tim's emotional journey forced him to realise that environmental scientists can no longer just observe. They need to find new prisms with which
