Naked Scientists, In Short Special Editions Podcast

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 tr...

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 t...

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....

We get so many good questions sent to us here at The Naked Scientists, that sadly we can't fit them all into our monthly question and answer shows. So here's an extra slice of science for you from our November 2018 QnA. Roger got in touch to ask whether artificial intelligence will be making medicines in the future, and we also heard from Sean about some rather intelligent ravens... Like this podc...

Glioblastoma is an aggressive and often deadly cancer of the brain. Understanding it is vital to improving patient outcomes. In a new study published in Nature Genetics, a group in Cornell University has been sequencing genes to understand which ones are switched on by the tumours. To learn more, Adam Murphy spoke to Charles Danko, of the Baker Institute for Animal Health and the Cornell College o...

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 ta...

Astronomers at the University of Hertfordshire have come up with an explanation for the wobble seen in jets of matter being blasted from regions surrounding some supermassive black holes: Another nearby supermassive black hole! Dr Martin Krause tells us how we can see them at all... Like this podcast? Please help us by supporting the Naked Scientists

Nowadays, tuberculosis takes more lives than any other infectious disease. Cases are on the decline but emerging antibiotic resistance threatens to interrupt that pattern. Tamsin Bell spoke with Professor Francois Balloux from University College London to learn about how this infectious disease evolved... Like this podcast?

We all know that drinking alcohol is bad for us but in the UK we still pay a huge 3.5 billion annually for the National Health Service (NHS) to treat over 60 alcohol induced medical conditions including liver disease, pancreatitis, diabetes, heart disease and numerous forms of cancer. Fortunately, it seems that the message to put down the booze has trickled down to the younger generation as a rece...

From right here on earth to the furthest visible parts of the universe, NASA has its eye on pretty much everything in between. Professor Andrew Coates from University College London was lead co-investigator in the joint ESA-NASA Cassini-Huygens mission to Saturn, and is involved in several further NASA missions of space exploration. With NASA turning 60 this month, Sam Brown spoke to Professor Coa...

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 t...

Antibiotic resistance is one of the greatest threats facing mankind today. A new group in the University of Washington in Seattle, have been working to fight this threat. In a new study, they've been looking to poison bacteria using the heavy metal gallium, to improve the lives of those with cystic fibrosis. Adam Murphy spoke to two authors of the study. First, Christopher Goss and then colleague,...

Imagine going into space. You've got your kit, you're blasted into darkness, you're ready to discover the unknown but then your equipment doesn't quite fit the task required. How can you prepare for that? This is a reality that space engineers and robotic experts are trying to facing every day. Now, researchers from Yale think they've got an answer. They've developed something called "Omniskin" -...

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...

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...

We've all been there at some point - you raise your hand in class, answer the question, and get it utterly, utterly wrong. These school-day humiliations may stay with us many years later, in fact - I'd love to hear yours, but as our kids are all headed back to school this week, we're trying to find out if perhaps these mistakes are good for us! Georgia Mills is on the case, but only after finding...

These days, many of us are heavily dependent on our trusty sat navs to get where we want to go, but looking at these devices whilst driving is incredibly dangerous and can lead to car accidents. Psychologists from Anglia Ruskin University are hoping to minimise the dangers of using this technology by incorporating audio cues with in-car GPS to forewarn the driver of the lay of the land. Tamsin Bel...

Goats can tell apart human facial expressions and - what's more - prefer to interact with happy people, according to a new study from scientists at Queen Mary University of London. We knew work animals like dogs and horses could do this, but no-one knew if animals domesticated for food products would be able to. Georgia Mills spoke to lead researcher Alan McElligott to find out how they did it Lik...

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...

From artificial photosynthesis to the art of statistics, the Naked Scientists take Jenny Zhang and Richard Samworth, two of St John's College's leading scientists, for a trip down the river to hear all about their work. Like this podcast? Please help us by supporting the Naked Scientists

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...

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...

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 va...

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, Universit...
