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.
Earlier this year a devastating heatwave in the pacific northwest of the United States killed almost 200 people with record-shattering temperatures; and, in 2019, the UK recorded its highest ever temperature of 38.7 degrees here in Cambridge. Alarmingly, new research from the Swiss Federal Institute of Technology suggests that there's…
A question we're being asked quite a lot is whether the extra lengths we're going to in terms of hygiene to protect us from COVID-19 might cause us immune problems later because we're living lives that are too clean. This is the basis of what's dubbed the "hygiene hypothesis". But…
The general view is that waterways, such as rivers and underground water sources, will dry up during severe drought - but eventually recover and resume their normal flow when the rains return. But new findings from Australia pour cold water on that idea. When researchers analysed 30 years of rainfall…
An ancient skull, uncovered decades ago in China, has recently been revealed to be possibly the closest ever relative to humankind. It's called "Dragon Man", and based on trace uranium inside the skull, it's been dated to at least 146,000 years old - but could well be much older! This…
Few animals inspire the imagination like Tyrannosaurus rex. And the mighty tyrannosaurs did dominate the lands that eventually became central Asia and western North America for millions of years. But during that time, fossils show that medium-sized predators all but disappeared. Why? Thomas Holtz from the University of Maryland dug…
Previously, researchers knew that sharks can travel back and forth across entire oceans, accurately returning to specific locations. But what we didn't know was whether they memorise these routes, or if they have some sort of inbuilt GPS. To find out how sharks navigate, Charlotte Birkmanis mapped the course with…
New technology may help save bees by providing an antidote for deadly pesticides. The new solution allows beekeepers to feed their bees 'pollen patties', a pollen-sized microparticle filled with enzymes to prevent the bees from ingesting certain pesticides. Carlotte Birkmanis chatted with Cornell University's James Webb to get the latest…
Covid viruses, vaccines and variants: Chris Smith talks to Radio New Zealand National to bring Kim Hill up to speed with the latest developments on the pandemic front, including the recent case in NZ's Wellington... Like this podcast? Please help us by supporting the Naked Scientists
Eastern Australia is currently in the grips of a mouse plague. Mice live everywhere people do, often undetected. Right now though, highly favourable conditions have caused mice populations to explode in the eastern states of Queensland and New South Wales. A year of abundant rainfall after several years of drought…

Scientists have reported on some unusual things flying in space recently. In one paper, sperm, stored aboard the International Space Station for the last 5 years, has been brought back to Earth and used to fertilise eggs. Also, a group of glow-in-the-dark bobtailed squid headed spacewards to look at how…
The world is always on the lookout for new drugs - but they're not easy to make. Synthesising them is often an expensive and prolonged process. But what if we could employ a miniature assistant to do it for us? That's what a team from the MRC Laboratory of Molecular…
For thousands of years, humans have used traditional mining techniques involving sinking tunnels or large pits to recover relatively small amounts of useful metals like gold and copper. What remains is usually, at best, a scar on the landscape, large amounts of waste material, and habitat destruction. At worst, the…
If you live in the UK, you should soon be able to drink vodka... from Chernobyl! Which might sound like a radioactive nightmare, but the stuff is - supposedly - completely safe to drink. Not only do radioactive particles get removed during the distillation process, there were few originally there…
It's often hardest to think when you've been working all day - especially if your job involves making lots of decisions. Psychologists call this decision fatigue. And evidence has shown that the phenomenon has serious, real-world consequences... beyond making you collapse on the sofa. Now, a study from the University…
The mantis shrimp is a sea creature with a particular party piece. While our eyes are sensitive to three colours, red, green and blue, which our brain uses to make the full rainbow of colours we see, the mantis shrimp is sensitive to 12 to 16 different colours, giving them…
Alexandra Elbakyan is the founder of the website SciHub, and it came out this week that she is being investigated by the FBI. You see, SciHub is an illegal venture: it makes research papers available for free to people who want them, bypassing the fees and subscriptions that journals would…
Noise pollution can be difficult to live with, and it turns out that plants are also impacted by too much noise, although not in the way you might expect. Jenny Phillips from Texas A&M in San Antonio has been studying the seedlings of native trees around gas wells in New…
Anorexia nervosa is a cruel, complex and serious mental health condition. It involves deliberately losing weight in order to keep body weight as low as possible. And through investigating brain circuits involved in regulating body weight and which can go awry in obesity, Roger Cone from the University of Michigan…
When they're trying to piece together our understanding of ancient Humans and Neanderthals, scientists often have to rely on artifacts found in caves. What scientists wish they had more of was ancient DNA, which would allow them to study how the populations of these groups changed and expanded over time…
