The link between cellular garbage disposal and Alzheimers disease Aug 14, 2017

Show notes

More than half a million people in the UK suffer from Alzheimer's disease. Symptoms of this disease, including memory loss and communication problems, are due to sticky protein build ups within the brain, called amyloid plaques. These plaques cause damage to nerve cells and are a hallmark feature of the disease. Currently, there is no cure for Alzheimer's disease. However, researchers at Yale University School of Medicine have made a striking discovery about the role of cellular garbage disposal units, called lysosomes, in the formation of these plaques. Lead researcher on the study, Shawn... Like this podcast? Please help us by supporting the Naked Scientists

Violence weakens short term memory Jul 28, 2017

Show notes

Short term memory is incredibly important in day to day life, whether you're driving to work, having a conversation, or reading through the Naked Scientists website. However, scientists from Princeton University have found evidence that exposure to violence reduces short term memory, even if the violent incident occured more than a decade ago. Alexandra Ashcroft spoke to Pietro Ortoleva to find out more... Like this podcast? Please help us by supporting the Naked Scientists

How Does Sleep Affect Dementia? Jul 21, 2017

Show notes

Alzheimer's Disease is one - very common - form of senile dementia. It usually affects older people and progressively robs them of their mental faculties. It occurs because a protein called beta amyloid builds up in the brain forming harmful deposits called plaques, which are toxic to nerve cells. What's confusing though is that the brain naturally makes beta amyloid all the time but seems to wash most of it away when we go to sleep. But what aspect of sleep is important for this clean-up process, and what are the implications for people who are chronically poor sleepers? At Washington... Like this podcast?

Searching for super-fast stars Jul 11, 2017

Show notes

Scientists now think they can explain why the hypervelocity stars - that's stars going at 600 - 1000 km per second are only spotted in one part of the sky, in the constellation of Leo, and it's down to their explosive origins. Douglas Boubert is a second year PhD student in the University of Cambridge, and he and his team used a computer model to try and work out what was going on. Georgia Mills heard what they found.

Can brain training slow the progression to Alzheimers? Jul 10, 2017

Show notes

Millions of people worldwide are affected by Alzheimer's Disease; Terry Pratchett was famously a victim of the condition, which progressively robs sufferers of their mental faculties. At the moment, no therapies are available to halt the disease, but it might be possible to keep patients functioning well, for longer, with a bit of brain-training. Cambridge University neuroscientists have invented a memory-boosting app called GameShow. Katie Haylor went to see the game's co-inventor Barbara Sahakian and lead scientist George Savulich...

What Causes Coastal Erosion? Jul 07, 2017

Show notes

Our coasts are constantly changing. And whilst human impact can have a significant impact Mother Nature also plays her part, tides and storms can change a beach overnight. Continuing with Marine Month, Chris Smith spoke to Oceanographer Simon Boxall from the University of Southampton about what's driving these changes and can we prevent them? Like this podcast?

Magnetic control of vision Jun 30, 2017

Show notes

If you're up for a bit of practical experimentation, give this a go. Hold your finger out in front of your face, fix your gaze on the tip and then shake your head from side to side, or nodding up and down. Without you having to think about it, your eyes stay locked on their target by precisely matching the movements of your head. But for some people, maintaining a steady gaze like that is impossible because their eyes rhythmically drift off. Luckily a British team of doctors and eye surgeons have come up with a solution based on an implantable pair of magnets. Chris Smith spoke to Parashkev... Like this podcast?

The Rise of Deadly Heatwaves Jun 29, 2017

Show notes

The third week of June had everyone searching for the suncream as temperatures reached record breaking heights. But while most of us enjoy fun in the sun, prolonged heatwaves can have significant health risks and can even be life-threatening. Izzie Clarke investigated just what is causing the surge in dangerous heatwaves and how we can stay cool as things start to heat up. Like this podcast?

What Lies Behind an Egg's Shape? Jun 29, 2017

Show notes

Many of us enjoy a boiled egg or two for breakfast, but why are hen's eggs round at one end and pointy at the other? Katie Haylor caught up with Mary Stoddard of Princeton University, who's trying to find out why eggs look the way they do. Like this podcast? Please help us by supporting the Naked Scientists

What is Wannacry? May 22, 2017

Show notes

In May 2017 hundreds of thousands of computers across the world were hit by a massive ransomware attack called Wannacry. The perpetrators encrypted the contents of users' computers and demanded payment to unscramble their data. What made the threat worse was that it had the ability to literally spread virally across the Internet by exploiting connections between computers on networks. But where did it come from, what can we do to mitigate the threat, and who is at risk of attacks like this? Chris Smith, Kate Feller and Andrew Holding put these questions to cybersecurity expert Paul Harris,... Like this podcast? Please help us by supporting the Naked Scientists
