00:54 Turning an undersea cable into a seismic detectorResearchers have shown that they can piggyback a signal on a 4,400-kilometer-long telecom cable that runs from California to Hawaii, allowing it to act like 44,000 separate seismic-activity detectors. Their method takes advantage of impurities found in glass fibre-optic cables, which reflect light differently when they are stretched and distorted by the pressure of seismic waves.Science: Seafloor telecom cable transformed into giant earthquake detector04:17 The origin of an ancient boatChemical analysis of the caulking found on the wood a...

Anecdotal stories suggesting that weight-loss drugs can help people shake long-standing addictions have been spreading fast in the past few years, through online forums, weight-loss clinics and news headlines. And now, clinical data are starting to back them up.Over a dozen randomized clinical studies testing whether GLP-1 drugs like Ozempic can suppress addiction are now under way, and neuroscientists are working out how these weight-loss drugs act on brain regions that control craving, reward and motivation.Scientists warn that the research is still in its early stages, but some researchers and physicians...

00:40 What a trove of potato genomes reveals about the humble spudResearchers have created a ‘pangenome’ containing the genomes of multiple potato types, something they believe can help make it easier to breed and sequence new varieties. The potato’s complicated genetics has made it difficult to sequence the plant’s genome, but improvements in technology have allowed the team to combine sequences, allowing them to look for subtle differences in between varieties.Nature Podcast: 16 April 2025Research Article: Sun et al.10:28 Hundreds of physicists on a remote isla...

Nature: Asteroids, antibiotics and ants: a year of remarkable scienceIn this episode:1:58 Evidence of ancient brine on an asteroidSamples taken from the asteroid Bennu by NASA's OSIRIS-REx spacecraft suggest the parent body it originated from is likely to have contained salty, subsurface water. This finding provides insights into the chemistry of the early Solar System, and suggests that brines might have been an important place where pre-biotic molecules were formed.News & Views: Asteroid Bennu contains salts from ancient brineNature Podcast: Asteroid Ben...

00:46 Evidence of the earliest fire Baked soil, ancient tools, and materials that could be used to start fires show that Neanderthals were making fire in the UK 400,000 years ago — the earliest evidence of this skill found so far. Ancient humans are known to have used naturally occurring fires, but evidence of deliberate fire-starting has been hard to come by. A new suite of evidence pushes back the date of fire mastery by 350,000 years. The team behind the finding believe it helps create a more nuanced picture of Neanderthals, who perhaps gathered round fires and told stories in ancient Europe. <br...

00:46 How satellite mega-constellations could ruin space-based astronomyThe ability of space-based telescopes to image the distant Universe could be in peril, according to new research investigating the impacts of light-pollution from future satellites. Streaks of reflected light from satellites currently in low-Earth orbit are already seen in telescope images, and planned launches could raise the number of satellites from around 15,000 to over half-a-million. Computer modelling revealed that this drastic increase would result in images taken by instruments like the Hubble Space Telescope becoming unusable by astronomers. The team propose a series of strategies to help mitigate these...

CRISPR-based gene editing has revolutionized modern biology, but these tools are unable to access the DNA that resides inside mitochondria. Researchers are eager to access and edit this DNA to understand more about the energy production and the mutations that can cause incurable mitochondrial diseases.Because CRISPR can’t help with these problems, researchers have been looking for other ways to precisely edit the mitochrondrial genome. And the past few years have brought some success — if researchers can make editing safe and accurate enough, it could eventually be used to treat, and even cure, these genetic conditions.<b...

00:46 Martian ‘micro-lightning’The sounds of ‘micro-lightning’ have been recorded by NASA’s Perseverance rover, ending a long search for the phenomenon on Mars. A lack of suitable equipment has made it difficult to gather evidence of lightning on the red planet, but a team of researchers realized that a microphone on Perseverance should be able to pick up the characteristic sounds of electrical discharges. In total they found 55 such examples, along with signs of electrostatic interference indicative of the phenomenon. They dubbed the electric bursts ‘micro-lightning’, as they are far smaller than the lighting seen on Earth, due to the thi...

00:45 A molecule that delivers insulin through the skinResearchers have developed a skin-permeable polymer that can deliver insulin into the body, which they say could one day offer an alternative to injections for diabetes management. The skin’s structure presents a formidable barrier to the delivery of large drugs but in this work a team show that their polymer can penetrate though the different layers without causing damage. Insulin attached to this polymer was able to reduce blood glucose levels in animal models for diabetes at a comparable speed to injected insulin. While further research is required on...

Yoshua Bengio, considered by many to be one of the godfathers of AI, has long been at the forefront of machine-learning research . However, his opinions on the technology have shifted in recent years — he joins us to talk about ways to address the risks posed by AI, and his efforts to develop an AI with safety built in from the start. Nature: ‘It keeps me awake at night’: machine-learning pioneer on AI’s threat to humanity Hosted on Acast.

00:45 A coronal mass ejection from a distant starResearchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. However, despite decades of searching, these signals have only been identified from the Sun. Now a team has identified a similar signal coming from a distant star in the Milky Way. They hope their discovery will lead to better understanding of the impact these colossal...

00:45 The debate around NanotyrannusA hotly debated species of dinosaur, assumed by many to be a juvenile T. rex, is actually a separate species, according to new research. Nanotyrannus was a dinosaur anatomically similar to T. rex, but about a tenth of the size, leading many to argue it was a young version of the iconic species. However, examination of the limb bones of a well-preserved Nanotyrannus fossil suggests it was close to finishing its growth and so would never become as large as a T. rex, leading the authors to argue that it is, in fact...

00:47 How bowhead whales live so longResearchers have uncovered a protein that enhances DNA repair and may explain how bowhead whales can live more than 200 years. The protein, cold-induced RNA-binding protein, was shown to enhance repair of double stranded DNA breaks, a particularly troublesome kind of damage. The team showed that this protein could also extend the lives of Drosophila flies and enhance repair in human cells. More needs to be understood about how this protein works, but the researchers hope that it could, one day, help prevent cancer and ageing in humans.Research Ar...

Advice on how to get good sleep is everywhere, with the market for sleep aids worth more than US$100 billion annually. However, scientists warn that online hacks and pricey tools aren’t always effective, and suggest that lessons learnt about the workings of a network of biological clocks found in the human body could ultimately lead to improved sleep.This is an audio version of our Feature: How to get the best night’s sleep: what the science says Hosted on Acast.
