Rocket-powered Punting Jul 31, 2015

Show notes

Punting is one of the most typically 'Cambridge' of activities, with hundreds of tourists being punted lazily along the river Cam at any one point during summer. Now, though, the Cambridge Science Centre has decided to liven things up a little with a rocket-powered punt, running on Chelsea buns from local cafe Fitzbillies. Yes you read that correctly! James Farr spoke to John London, the world's first 'punt-onaut' Like this podcast? Please help us by supporting the Naked Scientists

Sugary drinks increase diabetes risk by 20% Jul 31, 2015

Show notes

Fizzy drinks are often very high in sugar, and doctors suspect that they're likely to be linked to the growing rates of obesity in many countries. Now, by bringing together data from all of the previously published studies in the world, public health doctor Nita Forouhi has uncovered a strong link between sugary drinks and type 2 diabetes. In fact, as she explained to Amy Goodfellow, regularly consuming one sugar-rich drink boosts your diabetes risk by up to 13 per cent... Like this podcast?

Growing Human Hearts Jul 24, 2015

Show notes

Growing a human heart from a single cell may seem like science fiction, but scientists at the Gladstone Institute at the University of California San Francisco, have taken a huge step forward, by producing the first three-dimensional, beating, human heart chamber. Previously, it had been possible to produce a two dimensional sheet of beating heart cells, but to really gain an understanding of heart formation in a developing foetus and perhaps more importantly, how drugs given to women during pregnancy may affect this development, a three dimensional structure was needed. By treating stem cells... Like this podcast? Please help us by supporting the Naked Scientists

Volcanoes may have ended the Roman Empire Jul 17, 2015

Show notes

Volcanic eruptions can be both beautiful and destructive at the same time, but now scientists have found evidence they may have also been linked to plagues, and even the fall of the Roman Empire. When a volcano erupts, chemicals are released into the atmosphere in huge quantities, which reflect light away from the earth and therefore cause climate change, in the form of summer cooling. These chemicals are also locked away in the ice, providing a snapshot of the time of an eruption. Now scientists have dated the ice cores, and the records of summer cooling, from tree rings and have found they... Like this podcast? Please help us by supporting the Naked Scientists

Benefitting medically from marijuana Jul 15, 2015

Show notes

Marijuana has a reputation for helping people who are in pain. But achieving the analgesic effect comes at a cost: users of the drug complain of memory loss and mood disturbances. Now, by identifying the pathway in the brain that is responsible for these psychoactive side effects, University of East Anglia researcher Peter McCormick has found that in experimental mice it's possible to isolate just the pain killing actions Like this podcast?

Climate change is bad news for bees Jul 14, 2015

Show notes

It's hard to miss the fact that bees are in trouble, with worrying news of colony collapse disorder devastating bee numbers, and concerns about the effects of pesticides on our most important pollinators. Now there's something else for our buzzing friends to worry about: climate change! Jeremy Kerr and his colleagues at the University of Ottawa have been using museum specimens to track how bee populations have shifted over the past century. What they've discovered is that bees and climate change don't mix... Like this podcast? Please help us by supporting the Naked Scientists

Why do our brains age? Jul 14, 2015

Show notes

One of the key factors that makes the brain age has been uncovered by scientists in the US. Young mice infused with the blood of older animals developed a drop in their cognitive abilities. This is down to a chemical made by the immune system called beta2-microglobulin. Why it has this pro-ageing effect, we don't know; but, encouragingly, removing it reverses cognitive decline, and promotes the growth of stem cells throughout the body and brain. Chris Smith spoke to Saul Villeda and the University of California, San Francisco to find out more.... Like this podcast? Please help us by supporting the Naked Scientists

Predicting depression and anxiety Jul 13, 2015

Show notes

More than a quarter of people are affected by anxiety or depression each year. But are some people more at risk than others? By studying groups of rhesus monkeys, Dr Ned Kalin from the University of Wisconsin in Madison found that individuals displaying a trait known as "anxious temperament" may be up to 50% more likely to go on to develop anxiety disorders later in life, and the same seems to be true in humans...

RoboCabs: the key to curbing emissions? Jul 13, 2015

Show notes

How does being driven around in a robotic taxi grab you? Currently, cars contribute 13% to our greenhouse gas emissions worldwide. However, a new study has found that were we to switch to using a fleet of electrified, autonomous taxis - dubbed "robocabs" - we could reduce our emissions to next to nothing.Graihagh Jackson debated the merits of these self driving vehicles with the author of the study, the Lawrence Berkeley National Laboratory's Jeffrey Greenblatt...

Men and women may feel pain differently Jul 04, 2015

Show notes

It's an age-old debate, who feels more pain, men or women? Scientists at McGill University have taken us one step closer to answering this question with a study using mice. Jeff Mogil and his team have discovered that the biological pathway that causes chronic pain is completely different in male and female mice. If the same is found to be true in humans it could lead to gender specific, or 'his n' hers', painkillers in the not too distant future. Tom Crawford spoke to Jeff Like this podcast?
