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.
Martian rock discovery surprises scientists
There is a mountain located in the middle of a giant crater on Mars, but how it formed is still a bit of a puzzle for scientists. Investigations of the rocks below the surface of the crater have been helping piece together an answer. The Curiosity Rover currently on Mars…
Rocking adults to sleep
Lack of sleep or poor sleep is a problem that affects 1 in 3 people in the UK and America. Insufficient sleep is not only a health issue, contributing to heart disease, diabetes and obesity, but also an economic one. There's the direct costs of treating sleep disorders and their…
Muscles really do have "memory"
Nearly every cell in the body contains a part called the nucleus which houses the genetic information needed to function. Muscle cells are the largest cells in the body, so they often need multiple nuclei to meet high power demands. New research from the University Massachusetts at Amherst, supports the…
What's really in your e-cigarette?
It's common knowledge that smoking cigarettes is addictive, and this is because of the nicotine they contain. E-cigarettes are devices that heat up a liquid and produce an aerosol or spray which is then inhaled. If there's nicotine in the e-cigarette liquid then this gives a nicotine hit. In Australia,…
Rare Pigment Fossilised in Teeth
Brushing our teeth keeps them clean and free from debris, but back in medieval times, dental hygiene wasn't part of your daily routine. This means that scientists can look at the teeth of skeletons to reconstruct what food they might have munched on back then and find out more about…
Opioid overdose detection via app
Every day hundreds of people die when they accidentally overdose on opiate drugs, like heroin or morphine. These agents depress breathing, causing respiratory failure. But, if an opioid antidote is administered sufficiently quickly, then the situation can be reversed. And a team at the University of Washington have developed a…
Cheers to the Liver!
The Ancient Greeks understood that the liver was one of the most incredible organs humans possess when they wrote the cautionary tale of Zeus' punishment of Prometheus, in which poor Prometheus was tied to a rock where an eagle would eat his liver every day, but overnight it would regenerate…
Bio-inspired robot swarms
Biological systems are able to create complex shapes and patterns, like the stripes of a zebra, the shape of your hand or the dynamic displays of a flock of birds. These shapes develop in an emergent and self-organised way, relying on just local interactions between individuals. In contrast, human designed…
New test for cervical cancer
Cervical cancer is one of the most common cancers affecting young women, and it's caused by a virus called Human Papilloma Virus, or HPV, which is spread through sexual contact. The virus causes the cells of the cervix to keeping growing excessively, which eventually damages their DNA, causing cancer. Testing…
How to cut down on carbon this Christmas
Christmas is a wonderful time of year, but all of the additional transport and consumption adds up, and we are left with plenty of seasonal rubbish and greenhouse gases. So how can you cut down this Christmas? Georgia Mills is here to spoil all of the festive fun…
Solar-powered device cleans water
Clean water is something that we often take for granted, but making it can be a major technological and energy-intensive process. Now, thanks to a system developed by scientists at York University, Toronto, and MIT, there might be a way to do this much more cheaply in future. Hannah Laeverenz…
'Nano-tweezers' for single cell biopsy
How can seemingly similar cells behave differently? This is a particularly important question when a small change means that a cell does not function properly and several diseases might be the result of these small changes at the single cell level. But a cell is a complex system, and some…
Language development through childhood
Language is all around us, and good language skills are important for getting on in life. But does being good in one language domain, like spelling, mean you'll be good in another, like grammar? And if your child is doing well with language as a toddler, will they still be…
Cuddly Robots Feel Hugs
When we think of robots we might think of the Terminator, West World, or even something completely different like Big Hero Six - a story about a young boy and his soft medical robot companion Baymax. Doughy and malleable, a robot like Baymax is kind of the holy grail for…
Using gallium as an antibiotic
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 their study published September 2018, they looked to poison bacteria using the heavy metal gallium, to improve the lives of those…
Modelling Malaria
Every year, hundreds of millions of people contract malaria; this is a parasitic infection spread by mosquitoes. The parasite does two things when it grows in the body: either it clones itself to make millions more malaria parasites in that infected individual, and makes them sicker in the process; or,…
'Real' 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…
Cancer-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…
Can artificial intelligence make medicines?
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…
How 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…
