New solar cells Sep 29, 2014

Show notes

Hydrogen is regarded as an excellent candidate future fuel on the grounds that it is relatively easy to store and it burns cleanly to produce only heat and water. But present methods of production involve fossil fuels and are energy intensive, offsetting any benefits of the hydrogen. Instead, scientists would like to use electricity from renewable sources to split water into hydrogen and oxygen, with solar power being one obvious choice. Unfortunately, current silicon-based cells cannot produce a sufficiently high output voltage individually, meaning that several of them need to be linked... Like this podcast?

How dinosaur arms turned into bird wings Sep 29, 2014

Show notes

You can forget Jurassic Park because actually dinosaurs are all around us! And I'm not joking because the fact is that when you see a chirping bird, you're actually looking at a modern dinosaur. Evidence has been growing for some time that our feathered friends are descended from small carnivorous dinosaurs called therapods. For example, the arrangement of bones in a bird's fingers, encased in the wing, is very similar to the bones in fossilised therapods. But there are still some biologists who study early development, as a chick grows in an egg, who aren't convinced by the dinosaur story.Now... Like this podcast?

Common cold and asthma Sep 29, 2014

Show notes

During an asthma attack, inflammation in the airways leads to breathlessness, and severe cases can end up with sufferers being hospitalised or even dying.One culprit that can make asthma worse is the virus that causes the common cold, known as rhinovirus. But why does a cold mean a runny nose and feeling a bit grotty for most people, but can lead to dangerous breathing problems in asthmatics?Kat spoke to Imperial College's David Jackson, who's one of a team that has been finding out.

Do baby fish speak? Sep 28, 2014

Show notes

We've all heard that whales and dolphins have a highly developed way of making sounds to communicate with each. However when it come to ordinary fish you'd have thought they're pretty silent things. But you'd be wrong. Marine biologist Erica Staaterman from the University of Miami believes that most animals in the ocean including crabs, lobsters, shrimp and fish make sounds. In a new study she shows, for the first time, that 30 day old baby gray snapper fish speak to each other in order to stick together in the sea. Hannah Critchlow's been hearing from Erica, and her little snappers, over... Like this podcast? Please help us by supporting the Naked Scientists

Best place for cardiac arrest Sep 26, 2014

Show notes

A cardiac arrest is when a person's heart stops beating and they collapse. It affects 30,000 people every year in the UK.The majority of these occur outside the hospital setting and they're frequently fatal. But how should they be managed - by attempting to resuscitate the victim at the scene, or by rushing them to hospital in an Ambulance?Emergency Medicine specialist Bruce Adams, from the University of Texas Health Sciences Center in San Antonio says bringing the patient in is the best call, but Bristol-based emergency medicine consultant Jonathan Benger disagrees and says that calling an...

Worrying world population Sep 19, 2014

Show notes

World leaders had been planning for a world population of about 9 billion by 2050. But now a new analysis, based on fresh data and more advanced statistical methods, suggests that this estimate might be wildly inaccurate and that the real figure might be more than 12 billion, which means population policy might need a major rethink. Adrian Raftery at the University of Washington is the author of the new study... Like this podcast? Please help us by supporting the Naked Scientists

Ant-sized radios Sep 17, 2014

Show notes

Wireless connections are everywhere now. Perhaps you're listening to us through your smartphone or laptop, or maybe you have one of those new-fangled smart fridges connected to the internet.Technologists now talk about the internet of things, where objects around us are all connected up using wireless radio technology, and the potential applications are wide-reaching, from labelling banknotes to tiny bio-sensors for monitoring health.But one limiting factor is the size of the radio transmitter - a problem that may have now been solved by engineers in California. They've developed a... Like this podcast? Please help us by supporting the Naked Scientists

Modifying mice memories Sep 15, 2014

Show notes

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?

Sex and back pain Sep 14, 2014

Show notes

The karma-sutra for back pain may soon be arriving. Within the UK and abroad, there are striking percentages of men and women that report experiencing back pain, especially in later life, and this may be causing the bedroom to take a backseat for these couples. Now, recent research carried out by Natalie Sidorkewicz from the University of Waterloo, may help bring back the intimacy... Like this podcast? Please help us by supporting the Naked Scientists
