The problem with childbirth Oct 30, 2015

Show notes

Despite the hundreds of thousands of babies born every day, we still know relatively little about childbirth and how hormones play their key roles in it. A stress hormone, known as cortisol, is involved in inducing labour in animals, but doesn't seem to work the same way in people. A paper this week published in Science Signalling has suggested a potential way cortisol does have a part to play in human childbirth. Georgia Mills caught up with Professor Joe Herbert, from Cambridge University, to discuss the study. Like this podcast? Please help us by supporting the Naked Scientists

Frost prevented by new material Oct 28, 2015

Show notes

As Winter approaches in some parts of the world, so does the colder weather and the threat of ice on the roads and on your car windscreen. But help is at hand from Kansas State University's Alexander van Dyke. As he explains to Charis Lestrange, he's created what's known as a "biphilic" material that can stop frost from forming so easily on a surface. It consists of two types of material: one hydrophilic, which attracts water, and the other hydrophobic, or water-repelling. Placed in a certain pattern, these can keep water droplets moving so they don't have time to freeze... Like this podcast? Please help us by supporting the Naked Scientists

Is personality linked to birth order? Oct 24, 2015

Show notes

There have been many exaggerated reports this week that birth order, whether you are a first or last born, affects how intelligent you will be compared to your siblings. However, the researchers at the University of Leipzig found that this difference in intelligence is very small and the more important finding was about birth order and personality. Charis Lestrange spoke with lead author Julia Rohrer to find out more. Like this podcast? Please help us by supporting the Naked Scientists

Slippery steel that repels bacteria Oct 24, 2015

Show notes

Steel is used to manufacture a wide range of products from tiny surgical tools to huge ships. However, it can become corroded or contaminated when liquid comes into contact with it. A new method to coat steel with the compound tungsten oxide has been reported by researchers from Harvard University in Nature Communications this week. It enables liquid to slip off the surface while keeping the steel strong. Dr Ben de Laune, a materials chemist from the University of Birmingham, explains to Rosalind Davies why this is so important.

£21m for Engineering Grand Challenges Oct 21, 2015

Show notes

This week the UK science minister, Jo Johnson, was in Cambridge where he announced an initiative to pump 21 million into seven key research programmes intended to tackle some of the leading scientific and engineering challenges facing the world. The funding will come from the UK's Engineering and Physical Sciences Research Council, the EPSRC. Professor Philip Nelson is the EPSRC's chief executive, and he spoke to Kat Arney about how the projects were selected... Like this podcast? Please help us by supporting the Naked Scientists

Do people spread disease? Oct 09, 2015

Show notes

Every day millions of people are moving around the world by air, land and sea, but they may be bringing with them more than just their luggage. For example, during last year's ebola outbreak, there were concerns that air travel would spread the disease from west Africa to other countries, sparking a global pandemic. But were these worries justified? By studying the patterns of 187 diseases in 225 countries, Kris Murray and his team at Imperial College have discovered that it's geography, rather than air travel, that's the most important factor, as he explained to Kat Arney.

How are our lives are mapped on our brains? Oct 09, 2015

Show notes

The Human Connectome Project has collected data of hundreds of individuals ranging from brain imaging to genetic and lifestyle information. Now researchers from the University of Oxford have used this information to see how much our lifestyle choices and personality traits are reflected in our brains. Karla Miller explained their findings to Connie Orbach. Like this podcast? Please help us by supporting the Naked Scientists

Getting high from marathon running Oct 09, 2015

Show notes

You know when after a run you feel great? Well previously scientists thought this runners' high was down to endorphins, but this may not be the case. Johannes Fuss from the University of Heidelberg found that mice that ran around all day felt less pain and less anxiety - key features of a runner's high. However, this feel good sensation wasn't down to endorphins, but endocannabinoids - the same chemicals that come from smoking cannabis! Rosalind Davies jogged on over to find out more...

Extinct animal colours revealed Oct 08, 2015

Show notes

Fossils have long been used to help us piece together the size and shape of extinct animals, but the colours of these animals has, until now, been something of a mystery. Now researchers from the University of Bristol have detected the chemical signatures of the original melanin pigments in ancient bat fossils. Charis Lestrange spoke with Jakob Vinther to hear how...

Concussion and the Rugby World Cup Sep 30, 2015

Show notes

This week, with the Rugby World Cup in full swing, the sports chief medical officer, Martin Raftery has called for changes to be made to the rules in order to cut the number of concussions suffered by players. Concussion occurs when the brain is shaken around inside the skull. This damages nerve cells and blood vessels, and the effects of the damage are worse if a person is already suffering from a prior concussion. Finding ways to spot who is concussed, and when it's safe for them to play on, is a priority. Ginny Smith spoke to two scientists studying concussion. First, Michael Grey, from the...
