Scientists have been able to alter the emotional associations of memories mice by using a technique called optogenetics, which involves shining lights inside the brain. Roger Redondo explained to Georgia Mills how they reversed emotions at the brain cell level, and what this could mean for treating emotional trauma in humans. Like this podcast?

You may have heard reports of seemingly healthy young athletes suddenly dropping down dead in the middle of a game. Professor Paulus Kirchhoff from the University of Birmingham studies the genetic defects that lead to this condition- a rare form of heart disease which exercise actually makes worse.At the British Science Festival, Ginny Smith wanted to find out more. She started by asking him how big a problem this condition really is. Like this podcast? Please help us by supporting the Naked Scientists

Have you ever heard of someone dying of a broken heart? In fact, it is remarkably common for elderly people who were previously healthy to die soon after their spouse. But why? New research from the University of Birmingham has discovered that it is down to reduced functioning of the immune system during times of stress. This leaves older people susceptible to bacterial infections like pneumonia, which can be deadly. At the British Science Festival, Ginny Smith caught up with Dr Anna Philips and asked her why she had decided to study the health of people after they had lost a loved one. Like this podcast?

Cancer is one of the world's biggest killers, and current treatments often have terrible side effects. So scientists have begun looking into ways to help the body's own defenses fight back. When have a bacterial or viral infection, our immune systems go into overdrive to tackle the invader and protect our bodies. If it were possible to harness this line of attack and use it against cancer, this could open up a whole new method of treating the disease.At the British Science Festival, Ginny Smith talked to Louise and Vanessa, both PhD students at Birmingham University, about their research on...

Have you ever seen somebody in the street and thought you know them, until you get closer and realise it's a different person entirely. Matching faces to memories or pictures is easier for some people than it is for others. But what happens if you're job is dependent on being able to tell the difference between a 2D face in a photo and a person standing in front of you? Hannah Tooley spoke to Dr Rob Jenkins from the Department of Psychology at York University. He's been studying passport control officers in Australia to see how good these professionals are at it, and the results might surprise... Like this podcast?

Going back through the generations, eventually you come to the ancestor of all life on earth, something scientists call LUCA (last universal common ancestor).LUCA lived on a hydrothermal vent deep under the ocean, and probably used energy from the natural acidic gradient to survive and reproduce, using a generator called ATP-synthetase. But now Victor Sojo and his colleagues at UCL have come up with an explanation for what might have gone on, suggesting LUCA has a leaky membrane, which might explain some mysteries surrounding bacteria and archea. Kat Arney asked Victor how this leaky membrane... Like this podcast? Please help us by supporting the Naked Scientists

One of the remarkable things about the Deepwater Horizon oil spill in the Gulf of Mexico four years ago was the fact that a lot of the contamination was cleaned up by bacteria which simply ate the oil.Now there's more understanding of how microbes exist in oil which could lead to new technologies for extracting energy from oil deposits deep underground.A group of scientists have been studying an asphalt lake in Trinidad and Tobago where it was previously thought microbes couldn't live because of the lack of water, but now microbes have been found.Professor Joel Kostka from the Georgia...

Hello I'm Naked Scientist Hannah Critchlow and I'm concerned about aging. Alzheimer's disease affects around half a million of us in the UK alone, and this number is predicted to increase as the population gets older. However, this week a study suggested that up to a third of cases could be preventable just by changing the way that we live. I spoke to Carol Brayne, Professor of Public Health at Cambridge University. In a collaboration spanning countries, researchers analysed data published from decades of research on 10000s of people across the world and identified several risk factors that... Like this podcast?
