    Huge eruption on a distant star confirmed at last

    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 events might have on the atmospheres of exoplanets, and their chances of being habitable. Research Article: Callingham et al. 12:28 Research HighlightsVideo footage of a devastating earthquake provides a first-of-its-kind glimpse of a dramatic ground rupture — plus, a flock of comets seen outside our Solar System. Research Highlight: Single video camera tells the story of deadly Myanmar quake Research Highlight: A host of ‘exocomets’ swarms a distant star 14:29 The rare genetic variants that may increase the risk of ADHDAttention-deficit/Hyperactivity disorder (ADHD) is a condition that affects around 1 in 20 young people, but its underlying causes are not fully understood. Now, a team of researchers show that three rare genetic variants are implicated in an increased risk of ADHD, which may play a role in the neurons involved in dopamine signalling. While this work provides a better understanding of the complex genetics at play, the authors caution more research is needed to unpick the complex interplay other factors involved in ADHD. Research Article: Demontis et al. 18:41 Briefing ChatA high-resolution digital map for Roman roads, and how speaking more than one language could slow brain ageing.

    Meet the ‘Wee-rex’. Tiny tyrannosaur is its own species

    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, a different species. Research Article: Zanno and Napoli News and Views: T. rex debate settled: contested fossils are smaller rival species, not juveniles News: ‘Teenage T. rex’ fossil is actually a different species Video: Hotly debated dinosaur is not a tiny T. rex after all 08:46 Research HighlightsAn artificial ‘neuron’ could pave the way to build a brain-inspired computer — plus, how bats buck the trend by hunting prey their own size. Research Highlight: Artificial brains with less drain Research Highlight: By the time you hear these bats, it’s too late 11:19 A less invasive way to prevent breast cancerAn ‘anti-hormone’ therapy has shown promise in halting the onset of hallmarks associated with breast cancer, in a small trial. Breast cancer is a leading cause of death in women worldwide, but preventative measures, such as mastectomies, are invasive. A new study examined the efficacy of a treatment that blocks progesterone, a hormone thought to play an important role in breast cancer progression. The therapy reduced both specific clinical markers of breast cancer and the number of cells that can become cancerous. Larger, longer trials are needed to show that this treatment could ultimately become part of a breast cancer prevention strategy, but the team think that this work shows the promise of this approach. Research Article: Simões et al. 18:41 Briefing ChatA new approach to speed up CRIPSR therapies reaching clinical trials, and how vocal cords could be healed using a tiny 3D printer. Nature: Personalized gene editing helped one baby: can it be rolled out widely?

    Bowhead whales can live for more than 200 years – this protein might be why

    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 Article: Firsanov et al. News: This whale lives for centuries: its secret could help to extend human lifespan 11:22 Research HighlightsA precise way to grow crystals, with lasers — plus, the specialist organ that allows stinkbugs to protect their eggs from wasps. Research Highlight: How to grow crystals when and where you want them Research Highlight: Stinkbug ‘ear’ actually hosts parasite-fighting fungi 13:31 An antivenom against a broad range of snakebitesResearchers have used ‘nanobodies’ to create an antivenom that works against 17 snake species’ venom. Snakebites kill millions each year, so getting the right antivenom can be life or death. But they are difficult to produce and often are very specific. Now, using nanobodies from llamas, researchers created an antivenom against a broad range of snake species’ venom. The new antivenom can now even be produced without the llamas, and the team hope it will pave the way for a more universal antivenom. Research Article: Ahmadi et al.

    Audio long read: How to get the best night’s sleep — what the science says

    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.

    Honey, I ate the kids: how hunger and hormones make mice aggressive

    00:48 How hunger, hormones and aggression interact in mouse brainsResearchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant amounts of pregnancy hormones, oestrogen and progesterone, also played a role. By investigating the neurons involved, neuroscientists showed how hunger and hormones are integrated by the brain to lead to aggressive behaviour. This could help researchers understand more about how multiple stimuli are interpreted by the brain, something much harder to study than single stimulus effects. Research Article: Cao et al. 09:35 Research HighlightsThe overlooked environmental costs of wastewater treatment facilities — plus, an ancient communal hunting system that lasted well into the eighteenth century. Research Highlight: Wastewater treatment produces surprising amounts of greenhouse gases Research Highlight: Andean peoples hunted and gathered long after they embraced farming 11:53 What generative AI could mean for higher educationAround the world, universities and students are scrambling to adapt to the use of generative AI tools such as ChatGPT. And while there is optimism that these tools could improve education, there are also concerns about the ways they could stifle independent, critical thought. We hear about the studies trying to unpick the potential impact of this new technology.

    New bird flu vaccine could tackle multiple variants with one shot

    00:46 A multi-variant avian flu vaccine that could enhance pandemic preparednessA vaccine capable of protecting against multiple strains of avian influenza virus might be a step closer, according to new research. The H5 subtype of avian influenza viruses has spilled over into mammals and is particularly concerning to researchers because of the risk that one of its variants may evolve to cause a pandemic. But because there are multiple variants of these viruses, it has been hard to pre-prepare vaccines. Now, a team has used information on how H5 viruses changed over time to design a vaccine that in animal studies provided protection against different H5 variants. They hope their approach could be applied to create stockpiles of a vaccine that could be used in the event of a pandemic, regardless of the variant that causes it.

    How stereotypes shape AI – and what that means for the future of hiring

    00:48 The stereotypes hidden in Internet imagesStereotyped assumptions about women’s ages and their perceived job suitability are enhanced by Internet imagery, according to new research. A study of hundreds of thousands of online images shows that women appear younger than men. This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or head of research, while women were linked to occupations like cook or nurse. The research shows that these biases have been embedded into the training data for AI models and could affect future hiring. The researchers caution that society is at risk of creating a ‘self-fulfilling prophecy’ where these stereotypes shape the real world. Research Article: Guilbeault et al.
