Oil production has multiple environmentally-devastating consequences - including creating of billions of gallons of salty, chemical-filled wastewater. Typically, companies dispose of this wastewater by pumping it deep underground. But a growing body of evidence shows that this pumping causes 'injection-induced earthquakes', most notably the Jones earthquake swarm: thousands of earthquakes that hav...

We have smartphones, smart watches, even smart fridges. But now, from a paper published in the journal Photonics Research, we could be seeing smart glass. Researchers from the University of Wisconsin-Madison created a piece of glass that can mimic machine visual perception, basically how smart phones recognize your face to unlock the device, without needing any camera sensors, computer chips, or e...

This month, join Chris Smith to hear how sleep deprivation sends your endocannabinoids skyrocketing and triggers a tendency to binge, how many new genetic mutations you inherit from your parents, the gene for behaviour that turned out to be nothing of the sort, what good and bad learners have in common with youTube influencers, and from online collective whinge to paper in eLife: the careers of ne...

One in five UK children are obese. The biological and social factors behind this are complex, but the long term consequences range from cardiovascular and liver disease to diabetes. Now, according to a new study, it may even affect the development of a child's brain too, with overweight children showing a thinner cortex in the parts of the brain concerned with self-control and decision-making. Spe...

Considering people's wellbeing in making policy decisions is becoming more and more important, but it's only in recent years that governments have started to record the subjective satisfaction of the population. A team of researchers is looking to fill in the historical gap for national mood by analysing the text of old books published in the US, UK, Germany and Italy and computing a National Vale...

Immunotherapy is the term used to describe techniques that provoke the immune system to attack and remove cancer. The argument goes that because the immune system is extremely specific in what it targets, and because it has a memory and can learn and improve its action as it goes along, this is a powerful weapon for fighting malignancies. But we need to show the immune system what to attack, which...

You're probably familiar with the 1966 science fiction film "Fantastic Voyage", where a submarine crew are shrunk to microscopic size and venture into the body of an injured scientist to repair damage to his brain. They're not quite at the stage of shrinking scientists yet, but engineers in America have invented a flexible robot - thinner than a piece of thread - that can be controlled using a mag...

What if the next refrigeration technology could be based on twisting and untwisting strands? A new paper published in Science by an international team of researchers explored how twisting and stretching can change the temperature of certain types of fibres, leading them to propose a new method for building fridges that are more efficient and more environmentally friendly than those used at present...

This month, doctors doing U-turns: the medical practices without much evidence to prop them up, wind-tunnel experiments reveal how geese fly at extreme altitudes, why mating makes bees go blind, stress remodelling the brain's myelin, and what goes on during a stint aboard the International Space Station? Join Chris Smith for a look inside the latest papers in eLife... Like this podcast? Please hel...

Mobile phone companies could be set to erect bigger and taller phone masts as part of government plans to roll out 5G networks and improve coverage in rural areas. How might taller masts help with connectivity - and what is 5G anyway? Tech-xpert and Angel Investor Peter Cowley explains to Chris Smith and Katie Haylor... Like this podcast?

Bacteria are becoming increasingly resistant to many of the agents we use to deal with them, including antiseptics. The bacterium Acinetobacter baumannii is one example and causes hard to treat skin, chest, and urine infections in hospitals. Now, a team at the University of Newcastle, Australia have discovered a gene that renders Acinetobacter resistant to the chemical chlorhexidine that's used in...

A research team from Virginia Tech, led by Ryan Pollyea, has found that earthquakes 8 kilometres below the earth's surface are increasing in intensity. Published in the journal Nature Communications, the team's work has found that a super-dense liquid called oilfield wastewater is seeping deep into the sheets of the earth, causing massive pressure changes that could be increasing earthquake intens...

A heatwave has been sweeping across Europe recently, causing record temperatures across the continent and creating a lot of consternation in the Naked Scientist office. But where do heatwaves come from. And what's going to happen in the future. Adam Murphy spoke to Manoj Joshi, professor of climate dynamics from the University of East Anglia, starting with what a heatwave even is. Like this podcas...

Your genome contains all of your genetic information, and it's pretty long - the Human Genome Project estimated that humans have between 20,000 and 25,000 genes. But according to synthetic biology, you can survive on only 473 genes! At least a very simple bacterium can. Of this "minimal genome", scientists previously didn't know what nearly a third actually did. Now Mark Wass has been telling Heat...

The world's largest patch of seaweed appears every summer in the mid-Atlantic. And since 2011, the Great Atlantic Sargassum Belt has been growing to even more monstrous sizes - thousands of kilometres long - and it's been clogging up beaches along the Americas with metres of stinking brown goo. Now, scientists in Florida and Georgia have used satellite tracking to figure out what's going on - as P...

The nervous system is a complicated network of specialised cells - neurons - that transfer information from one part of the body to another. To help our understanding of the nervous system in humans, scientists have mapped every neuron and every connection in a type of roundworm called C. elegans. Emma Hildyard asked Scott Emmons how this map was created and what it could mean... Like this podcast...

You might remember from a year or so ago stories of an alien fly-by. The unidentified object was famously referred to as Oumuamua, which means "scout" in Hawaiian. Now a paper just out in the journal Nature Astronomy has revisited the story to probe whether Oumuamua really is alien technology, or just a cigar-shaped hunk of rock hurtling through the solar system. Matthew Hall got in touch with co-...

In June, Izzie Clarke explored the extremely fast science of speed and headed to the race tracks with McLaren in their 600LT Spider supercar. But whilst Formula 1 and petrol racing have a huge fan base, we're also seeing the rise of electric racing, Formula E. In this bonus interview, Izzie spoke with Rodi Basso, Motorsport Director of Mclaren Applied Technologies, about the future of the sport. L...

With a rising global population, and the impending impacts of climate change, we need more food, and reliable food sources safeguarded for the future. But varying light levels mean that plant growing conditions aren't always consistent, as Katie Haylor has been finding out... Like this podcast? Please help us by supporting the Naked Scientists

In March 2016 the public voted to name a new polar research vessel "Boaty McBoatface", ultimately though, it was decided that "RRS Sir David Attenborough" was a more fitting choice. But the name "Boaty McBoatface" lived on and was instead given to one of the ship's autonomous submarine vehicles. And this week data from Boaty's first research mission in Antarctica has revealed a worrying new mechan...

Robots are increasingly used to take over repetitive tasks in industry and agriculture, but they are still limited in what they can do. This also means that humans still need to work alongside them and often things can go badly wrong. 13000 injuries and 60 deaths were caused by accidents due to contact with machinery between 2014-18 in the UK alone. Engineers are working on ways to make robots saf...

The world is facing a global fish issue - a fissue, if you will. One third of all fish stocks are being overfished, and most of the efforts to prevent this involve exclusive zones in the ocean managed by individual countries. But a study released this week shows how the world's fisheries are all closely connected in a "small-world" network, and how overfishing in one zone can affect all of its nei...

The chest disease asthma is becoming more common. It can lead to life-threatening breathing difficulties when the airways constrict and the lung tissue overproduces mucus; this is usually an allergic reaction that can be worsened by air pollution. But our understanding of what's going on in an asthmatic lung is still quite limited. But now for the first time, scientists at the Sanger Institute nea...

When it comes to understanding how the brain functions, scientists have done a great deal of work on studying macaque monkeys, our evolutionary relative. We share 93% of our DNA and in a lot of ways, our brains are very similar. Even for high level operations such as learning, memory and decision-making, our brains work in comparable ways.. However, when it comes to sound, scientists have discover...
