What can we learn from NASA's Dawn probe? Mar 06, 2015

Show notes

After a seven and a half year journey, and with a price tag just shy of half a billion Dollars, NASA's Dawn spacecraft finally has the asteroid Ceres in its sights. Ceres is a massive asteroid which sits among a clutch of much smaller boulders, pebbles and dust out beyond the orbit of Mars. This field of debris is the rocky rubble left over from the time when the inner planets, including the Earth, were first forming, about 4 and a half billion years ago. This means asteroids like Ceres can help to uncover the origins of Earth and the minerals and materials, including the water, that we have... Like this podcast?

FameLab: the snapping shrimp Feb 25, 2015

Show notes

FameLab is a competition where scientists battle it out to be the best at giving engaging short talks on their favourite areas of research. Six Cambridge-based finalists have been chosen by a panel of judges and we're hearing from a selection of them. In this episode we meet Daphne Ezer and hear about the fascinating (and terrifying) snapping shrimp... Like this podcast? Please help us by supporting the Naked Scientists

Holes give diamonds their colour Feb 22, 2015

Space Worms Feb 15, 2015

Show notes

Worms are about to help scientists to boldly go where no researcher has been before, by venturing into space to help us to understand how changes in gravity might affect our DNA. Although scientists don't think that the physical genetic letters of DNA can be altered by low-gravity space travel, or living on the Moon or another planet, there are signs that chemical markers, called epigenetic modifications, which control the activity of certain genes and can be passed on from parents to their offspring, can be altered by exposure to low gravity environments.

Detecting dark matter Feb 13, 2015

Show notes

It makes up most of the stuff in our universe, but we can't see it or weigh it - but we know it has to be there. This elusive substance is dark matter, and according to a new paper in the journal Nature Physics this week, it's all around us in our own galaxy - the Milky Way. To find out more about dark matter, and what this new map of the dark matter in our galaxy might tell us, Kat Arney went to speak to UCL astrophysicist Chamkaur Ghag, who's working on ways to detect dark matter here on earth.

Positive thinking improves your health Feb 07, 2015

Show notes

Has anyone ever told you to lose a few pounds? Get a bit more active? Work harder in school? We can sometimes become a bit defensive when given this type of advice even if we know it's probably the right thing to do. Now scientists have revealed how a simple activity - called self-affirmation - can improve the way we react to this type of advice, which can have positive effects on our health. Like this podcast?

Differences between male and female brains Feb 06, 2015

Show notes

Your brain is more complex and powerful than the world's biggest supercomputer, built while you're a baby growing in the womb from the recipes encoded in your genes. But how do your growing brain cells know which genes to use? The answer comes from epigenetic modifications - the special chemical markers that are put on your genes that help cells switch them on or off at the right time and in the right place. Helen Spiers from Kings College London has been finding out how these epigenetic changes are involved in building the brain, and how they could explain some of the differences between...

A novel approach to detecting interactions between scorpion venom and its target molecule could aid in the discovery of new drugs for treatment of a wide range of nerve disorders. Like this podcast? Please help us by supporting the Naked Scientists

Mitochondrial Diseases: 3 Parent Embryos Feb 04, 2015

Show notes

What are so-called "3 parent embryos", and what are the arguments for allowing it? Hannah Critchlow discussed the issues with MP Julian Huppert, who supported the recent motion to permit the process in the House of Commons... Like this podcast? Please help us by supporting the Naked Scientists

How close are we to the next mass extinction? Feb 02, 2015

Show notes

Around 250 million years ago our world was a very different place. Rather than the different continents we know today, there was only one giant land mass - Pangea - covered with plants and animals. But then something went horribly wrong. Over a few million years, more than 95 per cent of all species on the early earth were wiped out in an event known as the Permian mass extinction. So what caused it? One researcher who thinks he might know is Mark Sephton from Imperial College London and, as he explained to Kat Arney, this wasn't the first time that our world has come to the brink of disaster.
