Naked Scientists Special Editions

In this latest watery-themed Planet Earth Podcast, Richard Hollingham hears how the underwater world isn't the soundless place you might imagine. From chirping, gurgling and snapping sounds from busy coral reefs to clicking sperm whales, scientists are finding that all sorts of marine life use sounds to find a suitable home, to find a mate, to avoid being eaten or to communicate. First up, we hear from a marine biologist from the University of Bristol who explains how manmade noise might not affect just whales and dolphins, but also much smaller creatures that live in and around coral reefs. Later, Richard meets a British Antarctic Survey scientist to find out how fossils of tiny marine creatures called bryozoans give us clues about when the West Antarctic Ice Sheet last collapsed. We also hear the strange clicking sounds sperm whales use to communicate with each other, and find out how very far leatherback turtles can swim.

Dr Paul Fletcher explains the science behind delusions...

As the UK winter continues to bite, Sue Nelson tries to escape it all by going to visit a coral reef. Unfortunately for Sue, the coral reef is not in some sunny clime. Instead, it's an indoor coral reef at the brand new Coral Reef Research Unit at the University of Essex. Researchers are using the reef to look at the effects of ocean acidification on coral in a unique experiment. Sue meets David Smith and David Suggett from the Unit to find out exactly what they're up to. Later, Sue talks to Andy Morse from the University of Liverpool. Andy's an expert on the effects of climate change on the spread of infectious diseases. Sue finds out that as the climate changes and brings warmer and wetter weather, we might get more than we bargained for. Finally our correspondent in Antarctica - the British Antarctic Survey's medical doctor, Claire Lehman - meets a researcher who tells us how she finds out how the sea around the continent changes with the seasons.

This is a special edition of the Planet Earth podcast, featuring some of our favourite audio diaries from the past year. We've got scientists using cannons to study geese in Ireland, researchers collecting mongoose poo in Uganda, Darth Vader impressions from beneath Antarctic ice and tiger leeches in a researcher's pants. In the first feature, Tim Cockerill from the University of Cambridge gives us an insight into studying insects in pristine rainforests of northern Borneo, describing some of the downsides. Next, Michael Cant, also from the University of Exeter tells us how cooperative - or not, as the case may be - Ugandan mongooses are. We then head down to the freezing cold waters of Antarctica to hear how British Antarctic Survey doctor Claire Lehman gets on when she joins the dive team.

In this special episode of the Naked Scientists podcast, we explore the world of Functional Electrical Stimulation (FES), a technology allowing people paralysed from the waist down to row and cycle by using external electrodes to stimulate leg muscles. Michele Vanoncini investigates how it works, what benefits it can bring and meets some of the people who have used it to go for gold...

Dark gamma ray bursts have puzzled astronomers for over a decade. The energetic gamma ray events, known as Gamma Ray Bursts (GRBs), all have an afterglow visible in the X-ray part of the spectrum, yet only half were visible at optical wavelengths. The half that were not visible in optical light, known as dark gamma ray bursts seemed to indicate that there may be a new class of GRBs not previously understood. Louise Ogden spoke to Dr Patricia Schady of the Max Planck Institute in Munich, whose team has found that dark gamma ray bursts are not in fact all that exotic...

Red squirrels used to be the most common squirrel in Britain. But since the grey squirrel was introduced from the USA as an illegal immigrant in the late 1800s, their numbers have nose-dived. This is partly because the greys out-compete red squirrels for food: they feed on the ground and can digest unripe acorns, which red squirrels can't. But it's not just food; grey squirrels brought a deadly virus with them, which has hit red squirrel populations hard. Sue Nelson goes to a National Trust wood near Liverpool, one of the last red squirrel strongholds in the country, to find out how they have coped with the virus. Later Richard Hollingham goes to Glasgow to find out how scientists know what Antarctica's climate was like 50 million years ago. Even though it was in the same place as it is now, temperatures on the continent were surprisingly different from what they are today.

In this podcast from National Pathology Week 2010, we join Dr Alun Williams at the Natural History Museum to discover the importance of veterinary pathology. With some incredible examples from the animal kingdom, we'll explore the some of the conditions that animal pathologists help to diagnose, and find out how understanding animal disease can help make humans healthier.

We explore the role of pathologists in pregnancy and childbirth in this podcast from National Pathology Week 2010. We discover what we can learn from an ultrasound as well as other tests that can be run on an expectant mother. Plus, we discover the importance of newborn screening programmes and the prevention or diagnosis of conditions that can alter the course of a pregnancy.

In this podcast Richard Hollingham reports from an unusual and somewhat cold location - onboard the British Antarctic Survey's RRS James Clark Ross which was stuck in the ice for two weeks 1000 kilometres from the North Pole. He talks to researchers on the ship about their work, finds out exactly how dangerous polar bears can be and hears what it's like to dive in freezing cold waters. He also learns that the Arctic isn't the desolate, barren place you might at first imagine. No, it's full of life. Not just big stuff like bears, seals and gulls, but algae and microorganisms that literally keep our planet alive.

We go behind closed doors in this special podcast from National Pathology Week 2010, visiting the pathology labs at the world famous Great Ormond Street Children's Hospital. We'll discover the role that pathologists play in diagnosis and treatment of childhood diseases, including how metabolic diseases are identified and the role of newborn screening. Plus, we explore the labs themselves to see pathologists in action.

Professor Ron Laskey discusses the links between our DNA and Cancer to reveal how cells become cancerous as well as how our DNA can be targeted to treat cancers...

Does your shopping basket contain chocolate, biscuits and shampoo? If it does, you may be unwittingly contributing to the destruction of the some of the world's pristine rainforests. Manufacturers now use palm oil in a huge range of products, because it's so cheap. But virgin rainforest in some of the planet's last wildernesses is being destroyed at a dizzying pace to make way for palm oil plantations to keep up with our voracious appetites for the products the stuff is in. Richard Hollingham meets Tim Cockerill, who's just come back from Borneo, to find out how the plantations affect the animals and plants that live in the rainforests there. We also hear why charcoal is such an incredible material. Not only can it tell us there was a fire, but it can also provide a previously unseen glimpse into our past. Sue Nelson goes to Frensham Common in Surrey to find out more. Finally, Tim Cockerill shows Richard Hollingham his very own working flea circus.

In this month's podcast Professor Ron Laskey discusses the links between our DNA and cancer to reveal how changes to our DNA can cause cells to become cancerous, how DNA can be targeted as a method of treatment and also how we can analyse markers in our DNA for earlier diagnosis. Plus we answer audience questions including the effectiveness of vaccines against cancer and the difference between cancerous and pre-cancerous cells.

This month we probe down into the world of structural biology to find out just what this field is and the molecules it can enable us to see. We discover how visualising molecules such as DNA and proteins can help us understand the development of our nervous system, the repair of our DNA and find better treatments for conditions like hypertension and pre-eclampsia, as well as bring you the latest news and developments from Diamond.
