Special Editions
Probing the weird, wacky and spectacular, the Naked Scientists Special Editions are special one-off scientific reports, investigations and interviews on cutting-edge topics by the Naked Scientists team.
Cosmic Collisions: Supermassive black holes
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…
1000 years of Tuberculosis
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…
English youths drinking less
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…
NASA: Now and Next
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…
Using gene editing to wipe out malaria-transmitting 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…
Back to School: Why mistakes help us learn
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…
A new conductive and magnetic material
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…
Bonobo 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…
Audio cues improve driver safety
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…
Goats prefer happy people
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…
Origins 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…
The Science of St John's
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.
Testing 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…
How did early life evolve?
We often hear about the search for life on Mars, but could life begin outside our solar system? Izzie Clarke discussed the chemistry involved with astrophysicist Paul Rimmer... Like this podcast? Please help us by supporting the Naked Scientists
Evolution 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…
Chemputer: Chemistry goes digital
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…
Circumcision 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…
Blocking \'memory\' immune cells 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…
Growing 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…
Why living the high-life can shrink your arms
People all around the world are living the high life. That's to say, living their whole lives at high altitude. This lifestyle has an impact on their bodies, including upon how their bones grow. And one adaptation, Cambridge University's Stephanie Payne has found, is to alter the relative lengths of…
