00:48 New insights into tick-borne encephalitis Researchers have identified a key protein that helps tick-borne encephalitis virus enter the brain. In rare cases an infection can lead to serious neurological symptoms, but little was known about how the virus interacts with human cells. Now, a team show that a protein found on the outside of cells plays an important role in infection. In mouse expe...

Science journalist Lizzie Wade’s first book,  Apocalypse: A Transformative Exploration of Humanity's Resilience Through Cataclysmic Events  explores some of the cataclysmic events that humans have faced through history. Lizzie joined us to discuss what modern archaeology has revealed about these events, and the role these they’ve have played in shaping societies around the world. Apocaly...

00:50 The AI tool that predicts disease risk Researchers have developed an AI tool that can calculate a person’s risk of developing over 1,000 different diseases, sometimes years in advance. The system, called Delphi-2M, was trained to identify patterns of disease progression using 400,000 people's health records from data repository the UK Biobank. This training allowed it to predict someone’s fu...

In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time, known as gravitational waves. These waves were produced by the final spiral of two orbiting black holes that smashed into each other, sending ripples across the Universe.     In this podcast, Benjamin Thompson speaks to Cole Miller from the University...

00:45 Attributing extreme heat events to major energy producers Major energy producers increased the likelihood and intensity of heatwaves, according to research published in  Nature . Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would ha...

In 2016, Brian Wansink wrote a blog post that prompted scientific sleuths to investigate his work. They found evidence of data manipulation, and, after several news articles and two investigations by his institution, he would found to have committed misconduct, as defined by Cornell University. His work had been used to inform US policy around food, much of which has now been thrown into question....

Raising mosquitoes to tackle disease might sound like an odd concept, but that’s what a facility in Brazil is aiming to do. Millions of mosquitoes are produced there every week, but these insects carry harmless  Wolbachia  bacteria that curbs their ability to spread deadly human viruses.  Nature  reporter Mariana Lenharo visited the facility and told us all about her experience...

00:45 The ant queen that can produce two different species Researchers have made an unusual observation that appears at odds with biology: an ant, known as the Iberian Harvester Ant can produce offspring of two completely different species. Many ants need to mate with other species to produce workers that are a genetic mix of the two, known as hybrids. But in Sicily, a team found hybrid worker ant...

The search for signs of consciousness has expanded, thanks to advanced neuroimaging techniques. These tools allow researchers to detect consciousness in unresponsive humans, and now researchers are looking to develop tests that work in animals and perhaps even artificial intelligence systems of the future.  This is an audio version of our Feature:  How to detect consciousness i...

00:48 How the 18th-Century 'Great Fear’ spread across rural France In the late 1700s, rural France was beset with rapidly spreading rumours of aristocratic plots to suppress revolutionary ideas. But how, and why, these rumours were able to spread so quickly has puzzled historians. Now, using modern epidemiological modelling, a team suggests that a combination of high wheat prices, income and liter...

00:46 Electrochemical fusion Researchers have used electrochemistry to increase the rates of nuclear fusion reactions in a desktop reactor. Fusion energy promises abundant clean energy, but fusion events are rare, hindering progress. Now, inspired by the controversial claim of cold fusion, researchers used electrochemistry to get palladium to absorb more deuterium ions, that are used in fusion. Wh...

In this Podcast Extra, we discuss a report released by the US Department of Energy, which concluded that global warming is “less damaging economically than commonly believed”. However, many researchers say that the report misrepresents decades of climate science. We discuss how scientists are trying to coordinate a unified response amidst concerns that this report will be...

00:46 Tiny solar flyer Researchers have used a phenomenon known as thermal transpiration to create a solar-powered flying device that can stay aloft without any moving parts. The diminutive device, just one centimetre across, consists of two thin, perforated membranes that allow air to flow through the device, generating lift. Although only a proof-of-concept, the team hope that a scaled-up versio...

00:45 Researchers develop a new glue and test it on a rubber duck Aided by machine learning, researchers have developed a super-sticky compound that works as an underwater adhesive. Inspired by animals like barnacles, the team developed a new kind of a material called a hydrogel. The material is capable of securely fastening objects together even when immersed in salty water— a challenge for exist...

00:45 The deepest ecosystem ever discovered Researchers have dived down to more than 9,000 metres below the surface of the Pacific and discovered surprisingly complex communities of life living in deep ocean trenches. The new research shows an array of animal life that appears to be using methane as a source of energy. The researchers are planning more dives to learn more about this mysterious eco...

00:46 How hot can solid gold get? A new study suggests that gold can be superheated far beyond its melting point without it becoming a liquid. Using an intense burst from a laser, a team heated a gold foil to 14 times its melting point, far beyond a theoretical limit put forward in previous studies. The team suggest that the speed at which they heated the gold allowed them to shoot past this limit...

A simple methodological error meant that for years researchers considered drinking moderate amounts of alcohol to be healthy. Now plenty of evidence suggests that isn't the case, but errors like this still plague the scientific literature. So, how can the scientific literature become more error-free? In the first episode of this two-part series, to determine what steps can be taken to help clean u...

In this episode: 00:48 The ancient mega-predator with a ‘stealth mode’ The extinct marine mega-predator  Temnodontosaurus  had specialised adaptations to stealthily hunt its prey, suggests an analysis of a fossil flipper. Although  Temnodontosaurus  was a member of a well-studied group of marine reptiles called ichthyosaurs, its lifestyle has been a mystery due to a lack of pre...

00:48 The past 35,000 years of disease Ancient DNA evidence shows that the advent of agriculture led to more infectious disease among humans, with pathogens from animals only showing up 6,500 years ago. The DNA, extracted from human teeth, shows the history of diseases present in Eurasia over tens of thousands of years. The approach used could be a powerful way to understand how illness has shaped...

Questions and doubts about vaccines are on the rise worldwide and public-health specialists worry that these trends could worsen. But while the shift in public attitudes towards immunizations can leave scientists, physicians and many others feeling disheartened, a surge of research on vaccine hesitancy is starting to offer ways to address the issue. This is an audio version of our Feature  Ho...

In this episode: 00:45 Why animals evolve to be imperfect mimics Many harmless animals mimic dangerous ones to avoid being eaten, but often this fakery is inaccurate. To help explain why evolution sometimes favours imperfect mimicry, a team 3D printed a range of imaginary insects. The novel creatures were designed to mimic wasps with varying degrees of accuracy and the team then presented these mo...
