Muscles really do have "memory" Jan 25, 2019

Show notes

Nearly every cell in the body contains a part called the nucleus which houses the genetic information needed to function. Muscle cells are the largest cells in the body, so they often need multiple nuclei to meet high power demands. New research from the University Massachusetts at Amherst, supports the contradiction of a widely believed theory linking large cells and nuclei numbers. Jenny Gracie spoke with Professor Larry Schwartz to find out why the relationship may no longer be true... Like this podcast? Please help us by supporting the Naked Scientists

Whats inside your E-cigarette? Jan 21, 2019

Show notes

It's common knowledge that smoking cigarettes is addictive, and this is because of the nicotine they contain. E-cigarettes are devices that heat up a liquid and produce an aerosol or spray which is then inhaled. If there's nicotine in the e-cigarette liquid then this gives a nicotine hit. In Australia, nicotine is classified as a poison, so it's illegal to sell e-cigarette liquids containing it, they have to instead be "nicotine free". But while studying the potential health impacts of e-cigarettes, scientists have found that, surprisingly, out of 10 "nicotine-free" e-cigarette liquids, or... Like this podcast?

Rare Pigment Fossilised in Teeth Jan 20, 2019

Show notes

Brushing our teeth keeps them clean and free from debris, but back in medieval times, dental hygiene wasn't part of your daily routine. This means that scientists can look at the teeth of skeletons to reconstruct what food they might have munched on back then and find out more about their lifestyle. But recently a team of international scientists, lead from the Max Planck Institute for the Science of Human History in Jena, Germany, found something a little more peculiar fossilised in the teeth of a 1000 year old skeleton. Jenny Gracie spoke with Christina Warinner to unearth the mysterious... Like this podcast? Please help us by supporting the Naked Scientists

Opioid overdose detection via app Jan 18, 2019

Show notes

Every day hundreds of people die when they accidentally overdose on opiate drugs, like heroin or morphine. These agents depress breathing, causing respiratory failure. But, if an opioid antidote is administered sufficiently quickly, then the situation can be reversed. And a team at the University of Washington have developed a system that turns a mobile phone into a sonar device that can monitor a person's breathing and then sound the alarm if something goes wrong. Chris Smith spoke with Jacob Sunshine, an anaesthesiologist and assistant professor at the University of Washington, to discuss... Like this podcast?

Sleep quality and Alzheimers disease Jan 15, 2019

Show notes

One terrifying prediction is that, by mid-Century, up to 30% of adults will be affected by a form of dementia, chiefly Alzheimer's Disease. This happens when proteins called beta-amyloid, and tau, build up in the brain and damage nerve cells. But scientists think this begins to happen decades before a person develops Alzheimer's symptoms, meaning we might have an opportunity to intervene and change the course of the condition if we can tell who's affected sufficiently early. Now, researchers at Washington University in St Louis have discovered subtle changes in the patterns of brain waves we... Like this podcast? Please help us by supporting the Naked Scientists

Podcasts: Chris Smith talks to Lawrence Jones Jan 01, 2019

Show notes

Back in 2001, Dr Chris Smith launched a new show, The Naked Scientists, in the hope of making science accessible. It was one of the first radio programmes to be made into a podcast and is now one of the world's most popular science shows. In the past five years, the programme has been downloaded more than 50 million times. Dr Chris has travelled the world in search of the latest science topics and trends, through which he has won numerous national and international accolades. He joins Lawrence Jones MBE to discuss bringing science to life through podcasts, how the team are engaging more people... Like this podcast? Please help us by supporting the Naked Scientists

Cheers to the liver! Dec 21, 2018

Show notes

The Ancient Greeks understood that the liver was one of the most incredible organs humans possess when they wrote the cautionary tale of Zeus' punishment of Prometheus, in which poor Prometheus was tied to a rock where an eagle would eat his liver every day, but overnight it would regenerate and grow back, allowing his punishment to continue day after day. Now, in real life, the liver doesn't regenerate quite that quickly, but it is true that it has the ability to grow back and heal itself remarkably well. Georgia Mills spoke to liver scientist Auinash Kalsotra from the University of Illinois,... Like this podcast? Please help us by supporting the Naked Scientists

Bio-inspired robot swarms Dec 21, 2018

Show notes

Biological systems are able to create complex shapes and patterns, like the stripes of a zebra, the shape of your hand or the dynamic displays of a flock of birds. These shapes develop in an emergent and self-organised way, relying on just local interactions between individuals. In contrast, human designed technology is usually created by an external builder. But now, a team of roboticists and biologists have come together to design robot swarms that can self-organise into complex shapes. Hannah Laeverenz Schologelhofer spoke with Sabine Hauert from the Bristol Robotics Lab. Like this podcast? Please help us by supporting the Naked Scientists

New test for cervical cancer Dec 20, 2018

Show notes

Cervical cancer is one of the most common cancers affecting young women, and it's caused by a virus called Human Papilloma Virus, or HPV, which is spread through sexual contact. The virus causes the cells of the cervix to keeping growing excessively, which eventually damages their DNA, causing cancer. Testing for this cancer can be challenging: these days it involves using DNA tests to look for traces of the virus in a sample. But the viruses are very common, and only a small proportion of people carrying them will actually get cancer; so there are lots of false positives. Now researchers at... Like this podcast?

Carbon neutral Christmas! Dec 19, 2018

Show notes

Christmas is a wonderful time of year, but all of the additional transport and consumption adds up, and we are left with plenty of seasonal rubbish and greenhouse gases. So how can you cut down this Christmas? Georgia Mills is here to spoil all of the festive fun... Like this podcast? Please help us by supporting the Naked Scientists
