Ep 636Real fake tan fights cancer

Do you like to lie out on the beach in the summer, or are you more likely to be found hiding in the shade? Well, how you answer might depend on how quickly you seem to get sunburnt. We all know that we should wear sunscreen when out and about in the summer to protect our skin and so reduce our risk of skin cancer, but new research from the Weill Medical College of Cornell might allow us to ditch the sunscreen at some point in the future. Eva Higginbotham spoke to Dr Jonathan Zippin, a dermatologist and skin researcher, about his lab's key discovery in the science of skin. Like this podcast?

Ep 635Cancer-killing immune cells

When we think of our immune system, most of us will be familiar with the white blood cells that circulate around our body to target and kill the bacteria and viruses that make us sick. But, we actually also have a special type of immune cell sitting in some of our body surfaces, like our skin and our gut, and new research suggests that these cells might hold the key to future cancer and allergy treatments. Eva Higginbotham spoke to Professor Adrian Hayday from the Francis Crick Institute and King's College London, about his new paper describing the unique way these cells actually work, and why...

Ep 634How WW1 can help head injuries

Today marks 100 years since the end of World War 1. This conflict caused the deaths of around 16 million people, and the new developments in artillery meant that new and nasty injuries were defying our ability to treat them. Ironically, this meant WW1 actually lead to huge advances in medicine, and neuroscience. But, thanks to a charity, Headway, it's also helping people with brain injuries today.

Ep 631Targeting immune cells to treat periodontitis

Good dental hygiene is crucial in the fight against gum disease, which can lead to a common condition called periodontitis. It comes about when changes to the bacteria in the mouth cause a reaction called inflammation in areas around the teeth, potentially destroying tissue and bone and causing tooth loss. But quite why an altered microbiome causes this inflammation isn't known, so there are no targeted treatments, and surgery is the main option for severe cases. But now scientists have spotted that periodontitis patients have higher numbers of immune cells called TH17 cells in their mouths,... Like this podcast?

Ep 626Gene drive to wipe out mosquitoes

Mosquitoes spread diseases like malaria, and they are rapidly becoming resistant to the insecticides used to control them. So scientists are looking at the potential of using a genetic technique, called a gene drive, to solve the problem. This involves engineering a gene-editing system into the insects that targets and inactivates a gene called dbx - or doublesex - that is needed for the insects to develop normally. Critically though, only female mosquitoes, which are also the ones that bite, are affected by the change. This means that males are left unaffected and can spread the genetic... Like this podcast?

You may have heard of graphene, the so called wonder material set to revolutionise electronics but the difficulty to consistently add extra properties and scale up cheaply limits industrial use! Scientists have been looking for easy to make alternatives, such as a new class of materials called metal organic frameworks or MOFs. As the name suggests, they're made by combining two components: a metal and something called an "organic chain" which contains carbon with some other elements. These can be used to create new materials with exciting properties.The big problem is that scientists have not... Like this podcast? Please help us by supporting the Naked Scientists

Ep 622Bonobo Apes Won't Share Toys

Do you share food or do you bite the hand off anyone who tries? Chimpanzees, one of our closest relatives are in the latter category: they'll gladly share tools, but food's a no no. New research published in Proceedings of the Royal Society B has been looking into our other close relatives: bonobo apes. Bizarrely, while they'll gladly share food, woe betide anyone who touches someone else's tools or toys! So what does this say about us?

Ep 618Origins of childhood kidney cancer

Most of the people who develop cancer are adults, although a significant number of children succumb too. The signs are though that childhood cancers could have a different origin than the adult disease, which might also mean they can be treated in a different way. Cambridge University's Sam Behjati suspects that tumours in children form from foetal tissue that has failed to mature properly. And by comparing the genetic instructions operating in normal and cancerous kidney cells from children and adults, he's tracked down evidence to support his theory and found a host of new avenues to explore...

Ep 616Testing for Tuberculosis

Doctors think that one third of the world's population have been exposed to the bacterial infection TB, or tuberculosis. It can damage any tissue in the body, infect the skeleton and joints, and even cause meningitis, but most people develop chest disease and a cough, which is how it chiefly spreads. A major problem with controlling the infection is that the Mycobacterium tuberculosis bacteria can be very hard to culture in a laboratory, and they grow extremely slowly, which holds up diagnosis and also makes it tricky to tell quickly whether someone is actually responding to the treatment...

Ep 614Evolution of the Skeleton

Since Darwin's time scientists have been studying the skeleton of a type of fish that lived 400 million years ago called Heterostracans. These fish were covered in a tough exoskeleton, but scientists couldn't decide exactly where it came from. Was it a precursor to bone? To teeth? New research is suggesting all those old theories may be as dead and buried as the fish fossils, and this exoskeleton is just another way of making bone.

Ep 613Circumcision Prevents HIV

HIV is a global pandemic. Worldwide, about 37 million people are living with the virus, and there are between 3 and 5 thousand AIDS deaths every day. More worrying is that, despite intensive public health and safe sex campaigns, there are a further 3 to 5 thousand new HIV infections occurring every day, and despite decades of effort, scientists still have not yet managed to develop an effective vaccine. But one very powerful way to prevent infection is for men to be circumcised, which reduces their risk of picking up the virus by up to 80%. So is this a cost effective strategy to halt HIV...

Mixing chemicals together causes reactions and produces new molecules. With so many different chemicals in existence, there are infinite combinations that can be made, and millions of chemical reactions yet to be tried. But doing these tests is very time consuming, laborious and has a low success rate; it's also very susceptible to human failings, like bias and fatigue. To surmount this, University of Glasgow chemist Lee Cronin has invented a robot to test his chemical combinations for him. What's more impressive is that this robot can actually learn.

Ep 611Blocking immune memory cell survival to cure vitiligo

Vitiligo is an autoimmune condition, in which the immune system attacks the pigment-producing cells of the skin, leaving behind pale white patches. Although not dangerous in itself, vitiligo can be disfiguring, causing a great deal of distress to people suffering from it. There are treatments available for vitiligo - these include topical creams that suppress the immune attack on skin cells, and phototherapy, which uses UV light. However, these treatments are time- and effort-consuming, particularly if large areas of the skin are affected. Another problem is that they only work temporarily -... Like this podcast?

Ep 610Growing new blood vessels

Heart attacks come about when blood vessels in the heart are blocked, and without a supply of oxygen-rich blood, the heart muscle can die. This is called ischemic injury, and can also occur in other places in the body, potentially leading to tissue death and even limb amputation. But what if it was possible to re-build the blood vessels in the heart or in other areas of the body, to kick-start the circulation and prevent tissues from being starved of oxygen, and dying?

Ep 606Dementia in a Dish

In recent years, we've woken up to the massive problem that is dementia. This is where people progressively lose their cognitive faculties and Alzheimer's Disease is one well-known example. But scientists are increasingly realising that injury done to the brain by damaged blood vessels is probably the leading cause of dementia, but it's also the one that we know much less about. It happens when the very small blood vessels deep within the brain become narrowed, stiffened and leaky, which leads to progressive damage to the adjacent brain tissue, although we don't understand how this happens, or...
