The Naked Scientists Podcast

Chronic Fatigue Syndrome (CFS) sufferers describe symptoms of severe exhaustion, weakness, muscle pain and fatigue. But why, and what is science revealing about the underlying causes of the condition? We talk to a researcher who is probing the genetic links to the syndrome, a clinician with evidence that the muscles of patients accumulate acid when they exercise and a pathologist with post-mortem evidence of inflammation in the nervous systems of CFS sufferers. Also, in the news this week, the ants that help a pitcher plant to catch its lunch, the missile-hurling zoo chimp who plans his... Like this podcast?

This week we get Naked in Norway as we visit the University of Oslo to reveal the remains of ancient plesiosaurs and investigate their migration into water, discuss a new concept for more efficient solar cells and discover the fatal effects of climate change on lemming population cycles. We then scour more Scandinavian science to unearth the causes of mass extinction, find out a new way to overcome resistance to radiotherapy, tool around with chimps in the Savannah and round up with a scientific climax in bird masturbation!

Why does sunlight make me sneeze? What causes air turbulence? Why do energy-saving lights take time to warm up? In this week's question and answer show we also investigate why microwaving a dishcloth causes it catch fire, whether mining could change the Earth's orbit and why streetlights shine with an orange glow. In the news, meanwhile, how electrical brain stimulation can make impossible problems tractible, a pint-sized rocket to take spacecraft to the moon and a tornado spotted on the surface of the Sun...

This week we're exploring the future of nuclear energy, including meeting the makers of a new design of nuclear reactor that can consume the fuels that other plants can't burn. We also delve into ways to unclog pipes inside reactors without the risks of going inside. And where do you stand on the nuclear debate? Should we be exploring alternatives, or is there no alternative to a nuclear-future? We talk to two parties on opposite sides of the debate. Plus, what the Messenger probe has found on Mercury, a blood test to predict an imminent heart attack, flushing out evidence of drug use from... Like this podcast?

Immune-manipulating parasites, bacterial genomes married to disease processes and viruses that bounce off already-infected cells make for an infectious episode of the Naked Scientists this week. Also up for analysis, why the eyes vote no to long space journeys; the problem with prostate cancer prediction; why nanoparticles trigger bacteria to breed superbugs and the contagious question of which cancers you can catch...

Smart sensors can open a window into the environment. In this week's Naked Scientists Podcast we find out how networks of sensors around Heathrow airport can study how planes alter the atmosphere, and how a similar network can monitor an Oxfordshire floodplain. Plus, we find out how the tools of a surgeon are helping to keep jet engines in flying form. In the news, we hear how gut bugs promote blood vessel growth, why fresh fruit and veg gives you a healthy hue and how scientists are analysing antimatter with microwaves... Like this podcast?

How can we extract energy from waste? In this week's Naked Scientists we explore the technology that turns muck into methane and consider the fertile issue of nutrient overload resulting from returning the finished products to farmland. And what about water? Why do we individually use ten times more water than we actually need, and what's the solution for a drought-stricken Britain? Plus, in the news, how astronomers have discovered evidence of life in the universe, but only down here on Earth, and the "ungentlemanly" conduct of the upper classes... Like this podcast?

What's the point of earwax? Does WiFi damage the brain? Can a mobile phone in a trouser pocket dent a man's fertility? In this week's science Q and A show we also brush up on how they get the stripes in toothpaste, discover whether dropped food follows the 5 second rule and shed light on why some forms of EM radiation more damaging than others. Plus, news of a new microscopic MRI machine for molecules, how computer games can alleviate the symptoms of schizophrenia and why what a woman eats, even before becoming pregnant, can have a lifelong genetic legacy for her offspring...

A new liquid crystal laser that can dial-up any wavelength of light you need, a laser-powered projector technology that turns any surface into a touch-screen, and a laser that fires salvoes of X-rays to make light work of unlocking the molecular fabric of matter are the focus of this week's laser-led show. We also meet HECToR, one of the world's fastest computers that just got a tenfold power boost, and David Braben unveils the credit-card sized Raspberry Pi, the world's smallest home micro he's helped to invent...

Over two-thirds of the energy in the fuel you put into your car is wasted, most of it in the form of heat that exits along the exhaust pipe. The same is true of large-scale power stations, which are only 50% efficient at best. But now researchers are bringing 200 year old physics to bear against the problem by developing thermoelectric generators (TEGs) that can turn waste heat into useful electricity and this week we find out how. Plus, news that disguising cancer cells as Salmonella could hold the key to producing effective anti-cancer vaccines, why the Y chromosome boosts heart attack risk,... Like this podcast?
