Gaia Vince on how climate change will shape where people live
In the second episode of Nature hits the books, science writer and broadcaster Gaia Vince joins us to talk about her new book Nomad Century, which looks at how climate change could render large parts of the globe uninhabitable, and how surviving this catastrophe will require a planned migration of people on a scale never seen before in human history.Nomad Century, Gaia Vince, Allen Lane (2022)Music supplied by Airae/Epidemic Sound/Getty images.

Mysterious fluid from ant pupae helps feed colony
00:45 Inert ant pupae produce a previously unobserved fluidAnt larvae metamorphose into adults by pupating. It was assumed that these inert pupae don’t play a role in the wider ant colony, but a team of researchers have found that they actually secrete a fluid that is consumed by both adult ants and larvae. This fluid is rich in proteins and metabolites, and appears to be an important source of larval nutrition. These secretions have now been seen in the pupae of multiple ant species, suggesting it is an evolutionary ancient behaviour.Research Article: Snir et al.News and Views: A fluid role in ant society as adults give...

Audio long read: Science and the World Cup — how big data is transforming football
Big data is playing an increasingly important role in football, with technologies capturing huge amounts of information about players' positions and actions during a match.To make sense of all this information, most elite football teams now employ data analysts plucked from top companies and laboratories. Their insights are helping to steer everything from player transfers to the intensity of training, and have even altered how the game is played.This is an audio version of our Feature: Science and the World Cup: how big data is transforming football Hosted on Acast.

The satellite-free alternative to GPS
00:45 Precision positioning without satellitesSatellite navigation has revolutionized how humans find their way. However, these systems often struggle in urban areas, where buildings can interfere with weak satellite signals. To counter this, a team has developed an alternative, satellite-free system, which could improve applications that require precise positioning in cities, such as self-driving cars.Research Article: Koelemeij et al.News and Views: Phone signals can help you find your way in cities even without GPS09:19 Research HighlightsHow deforestation is the biggest threat to a rare lemur’s existence, and ultravi...

How a key Alzheimer's gene wreaks havoc in the brain
00:46 Artemis 1 is go!NASA’s Artemis 1 mission has successfully reached Earth orbit. After weeks of delays and issues, and a nail biting launch, the rocket marks the first step in a new era of moon exploration, with plans to test a new way to return astronauts to the moon.

Audio long read: She was convicted of killing her four children. Could a gene mutation set her free?
Kathleen Folbigg has spent nearly 20 years in prison after being convicted of killing her four children. But in 2018, a group of scientists began gathering evidence that suggested another possibility for the deaths — that at least two of them were attributable to a genetic mutation that can affect heart function. A judicial inquiry in 2019 failed to reverse Folbigg’s conviction, but this month, the researchers will present new evidence at a second inquiry, which could ultimately spell freedom for Folbigg.This is an audio version of our Feature: She was convicted of killing her four children.

Molecular cages sift 'heavy' water from near-identical H2O
00:49 Separating heavy water with molecular cagesHeavy water is molecule very similar to H2O but with deuterium isotopes in the place of hydrogen atoms. Heavy water is useful in nuclear reactions, drug design and nutritional studies, but it's difficult to separate from normal water because they have such similar properties. Now, a team have developed a new separation method using tiny molecular cages, which they hope opens up more energy efficient ways to produce heavy water.Research article: Su et al.News and Views: A molecular flip-flop for separating heavy water07:23 Research HighlightsHow dancers can feel the beat even...

Audio long read: The controversial embryo tests that promise a better baby
Companies are offering genetic tests of embryos generated by in vitro fertilization that they say allow prospective parents to choose those with the lowest risk for diseases such as diabetes or certain cancers. However, some researchers are concerned about the accuracy and ethics of these tests.This is an audio version of our Feature: The controversial embryo tests that promise a better baby Hosted on Acast.

Flies can move their rigid, omnidirectional eyes – a little
00:46 How flies can move their eyes (a little)It's long been assumed flies’ eyes don’t move, and so to alter their gaze they need to move their heads. Now, researchers have shown that this isn’t quite true and that fruit flies can actually move their retinas using a specific set of muscles, which may allow them to perceive depth. The team also hope that this movement may provide a window into some of the flies’ internal processes.Research article: Fenk et al.08:54 Research HighlightsHow the 80-year-old wreck of a sunken warship is influencing ocean microbes, and tracing an epilepsy-related gene variant back to a si...

Racism in Health: the harms of biased medicine
When COVID-19 hit it didn't kill indiscriminately. In the US, being Black, Hispanic, or Native American meant you had a much greater risk of death than if you were white. And these disparities are mirrored across the world.In this episode we explore the complex tale behind this disparity. Throughout history, racism and biases have been embedded within medical technology, along the clinicians who use it. Cultural concepts of race have been falsely conflated with biology. The way medicine is taught, has reinforced flawed stereotypes. Disease itself, has been racialised. All of this adds up to barriers to care and worse healt...

Ancient DNA reveals family of Neanderthals living in Siberian cave
In this episode:00:54 Siberian cave offers first-ever glimpse into Neanderthal familyBy analysing ancient DNA recovered from bone fragments found in two Siberian caves, researchers have identified a set of closely related Neanderthals: a father and daughter, as well as several other more-distant relatives. The work suggests that Neanderthal communities were small, and that females may have left their families to join other groups.Research article: Skov et al.News and Views: The first genomic portrait of a Neanderthal family09:14 Research HighlightsThe robotic falcon that frightens nuisance flocks, and how climate change co...

Human brain organoids implanted into rats could offer new way to model disease
In this episode:00:45 Implanted brain organoids could offer new insights into diseaseBrain organoids — lab-grown, self-organizing structures made of stem cells — are used in research to better understand brain development and disease progression. However, these structures lack connections seen in real brains, limiting their usefulness. To overcome this, a team has now transplanted human organoids into the brains of newborn rats, showing that these implanted organoids respond to stimuli and could influence the animals’ behaviour.Research article: Revah et al.News and Views: Human brain organoids influence rat behaviou...

Virtual library of LSD-like drugs could reveal new antidepressants
In this episode:00:46 A virtual chemical library uncovers potential antidepressantsCertain psychedelic drugs are of interest to researchers due to their promising antidepressant effects. To help speed up the discovery of molecules with useful properties, researchers have built a virtual library of 75 million compounds related to these drugs. This approach yielded two molecules that showed antidepressant properties in mice, but without the hallucinogenic activity of psychedelic drugs.Research article: Kaplan et al.Research Briefing: Bespoke library docking for 5-HT2A receptor agonists with antidepressant activity08:25 ...

Nature's Take: How the war in Ukraine is impacting science
The ongoing war in Ukraine has devastated the global economy, rocked geopolitics, killed thousands of people and displaced millions. Science too has been affected and the impacts on research are being felt more widely than just in Ukraine and Russia.In this episode of Nature's Takes we discuss the war's impact on publishing, international collaborations, climate change and energy, and the destructive impacts on scientists themselves. And as the war continues, we consider the future of science in the face of a new political climate. Hosted on Acast. See acast.com/privacy for more information. (Source: Nature Podcast)
