00:45 The deepest ecosystem ever discoveredResearchers 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 ecosystem and how these animals can thrive despite the extreme pressure they face.Research Article: Peng et al09:36 Research HighlightsA fossilized leg bone reveals an 11-million-year-old fight between a terror bird and a caiman, plus the anti-ageing secret of ‘immortal’ stars.Research Highlight: Rumble in the Miocene: terror bird versus caimanResearch Highlight: ‘Immortal’ stars have an elixir of youth: dark matter11:45 How infections could awaken dormant cancerNew research reveals that infection by a respiratory virus has the potential to awaken dormant cancer cells. In mice studies, a team showed that inflammation caused by infection with influenza or SARS-CoV-2 could initiate the awakening of breast cancer cells that had metastasized to the lungs. Observational studies using human health data also showed that a COVID-19 infection was associated with increased risk of lung metastasis and cancer death. While the precise mechanisms are unknown, the team say that understanding the process could help mitigate any risks of cancer progression caused by a viral infection.Research Article: Chia et al.News and Views: Inflammation during viral infection can rouse dormant cancer cells21:45 Will physicists ever agree on quantum mechanics?A survey of more than 1,100 physicists has revealed that there are widely different interpretations of what quantum mechanics means for our understanding or reality.

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, but there is scepticism about whether the team actually achieved the level of heating they report.Research Article: White et al.News and Views: Solid gold superheated to 14 times its melting temperatureNews: Superheated gold stays solid well past its predicted melting point10:05 Research HighlightsHow island life led to huge wingspans for flying foxes, and how a sugary diet ‘rewires’ a mouse’s brain.Research Highlight: How the world’s biggest bats got their enormous wingspansResearch Highlight: How sugar overload in early life affects the brain later12:30 Researchers warn about the threat of nuclear warWith increasing political polarisation and more nuclear-armed nations, researchers are warning about the threat of nuclear war.

00:48 The past 35,000 years of diseaseAncient 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 humanity, but it is unable to detect some bacteria that enter the bloodstream at low concentrations or some viruses, so future work could seek to fill that gap.Research Article: Sikora et al.News: Animal diseases leapt to humans when we started keeping livestock10:58 Research HighlightsDNA studies confirm that sardines were a major ingredient of the Roman Empire’s favourite fish sauce, and how analysis of animal manure identified global hotspots for antibiotic-resistance genes.Research Highlight: Ancient DNA helps trace stinky Roman fish sauce to its sourceResearch Highlight: Poo of farm animals teems with drug-resistance genes13:17 Using whale poo to study toxic algae in the ArcticA 19-year experiment sampling bowhead whale faeces reveals a link between warming Arctic waters and increasing levels of toxic algae, researchers say. While climate change is expected to drive increases in the prevalence of harmful algal blooms, long-term data is lacking. To address this, a team worked with indigenous communities to collect and sample whale poo, showing that increases in algal toxins in the Arctic food chain are linked to rising ocean temperatures. The researchers suggest levels of these toxins need to be closely monitored to protect Arctic communities that depend on marine resources for food.Research Article: Lefebvre et al.24:06 Briefing ChatAn object from beyond our solar system has been spotted zipping past Jupiter, and evidence that Neanderthals created ‘fat factories’ to extract vital nutrients from animal bones.Nature: Neanderthals boiled bones in ‘fat factories’ to enrich their lean dietNature: Rare find: interstellar visitor seen blazing through our Solar SystemSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

By combining climate modelling with data from archaeological sites across the African continent, researchers put forward evidence that 70,000 years ago, humans expanded the ecosystems they lived in to include diverse habitat types from forests to deserts. The authors suggest this ability to live in different places may have helped the later humans that migrated out of the continent around 50,000 years ago.Research article: Hallet et al.21:59 Briefing ChatBlowing bubble-rings could be humpback whales' way of trying to communicate with humans, and the research suggesting that everyone’s breathing pattern is unique.Science Alert: Humpback Whale Bubble Rings May Be an Attempt to Communicate With UsNature: How you breathe is like a fingerprint that can identify youSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

00:45 A flexible neural-implant that grows with the brainResearchers have developed a soft electronic implant that can measure brain activity of amphibian embryos as they develop. Understanding the neural activity of developing brains is a key aim for neuroscientists, but conventional, rigid probes can damage growing brains. To overcome this, a team have developed a flexible mesh that stretches with the brain and tested it by monitoring single neuron activity during development of frog and axolotl embryos. More testing and ethical considerations will be required, but the researchers hope that eventually such implants could help with neurological conditions that affect humans.Research article: Sheng et al.13:11 Research HighlightsThe exoplanet slowly evaporating into space, and cockatoos that have figured out an innovative way to stay hydrated.Research Highlight: Solved: the mystery of the evaporating planetResearch Highlight: Clever cockatoos learn an easy way to quench their thirst15:30 An AI-based way to repair damaged paintingsBy combining AI tools with mechanical engineering techniques, a researcher has developed a new way to speed up the restoration of damaged paintings. The technique creates a removable mask that can be overlaid onto a painting to cover any damage apparent in the artwork.

00:45 Iron’s role in mice sex determinationIron deficiency in mice mothers can sometimes result in their offspring developing female sex organs despite having male sex genes, according to new research. While genetics has been thought to be the primary factor in determining offspring sex in mammals, the new work shows that a lack of iron disrupts an enzyme involved in the development of testes, leading to some mice with male sex-determining genes being born with female genitalia and ovaries. This suggests that sex determination is controlled by more than genetics, but more work will need to be done to understand the precise mechanisms involved.News: Male mice can grow ovaries if their pregnant mums are iron deficientResearch article: Okashita et al.06:31 Research HighlightsHow climate change is making dust storms more likely, and understanding the genetics of a boy who couldn’t feel pain.Research Highlight: The perfect storm for dust storms, thanks to global warmingResearch Highlight: CRISPR helps to show why a boy felt no pain08:51 The role of small-scale fishers in sustainabilityThe contributions that small-scale fishers make to sustainable fishing have been described as ‘invisible’, but now a huge research project has revealed the role this community plays in feeding populations and protecting oceans. Looking at data from 58 countries, researchers have shown that small-scale fishers account for around 40% of the global catch and feed approximately 25% of the world’s population.

00:46 An antimatter delivery van takes its first road tripResearchers have developed a portable antimatter containment device and tested it by putting it in a truck and driving it around CERN. Their system could represent a big step forward in efforts to take particles made at CERN’s ‘antimatter factory’ and transport them to other labs, something currently impossible due to antimatter being destroyed upon contact with matter. The team showed the feasibility of their approach by using the system to safely transport particles of matter and are now looking to adapt it to ferry antimatter particles.Research article: Leonhardt et al.11:45 Research HighlightsHow a tradition of female diving on a South Korean island might have shaped the genomes of the island’s population, and a poison-dart frog that curiously seems to be monogamous.Research Highlight: How Korea’s female divers have adapted to cold plungesResearch Highlight: A ‘hidden gem’ of the Amazon is a frog with odd habits13:46 The mathematics of a near-miss between black holesPhysicists have tackled a longstanding problem in physics — understanding how two black holes gravitationally interact as they fly past each other — which could help with future detections of the gravitational waves that would be created by these events. Rather than repeatedly running expensive computer simulations to approximate the answer to this problem, a team of theorists have come up with a mathematical formula to describe a black hole fly-by, which can be run in a matter of seconds. Their results could be used to identify the tell-tale signatures of these events when they actually occur.Research article: Driesse et al.22:10 Briefing ChatHow physicists turned lead into gold, for a microsecond and at tremendous cost, and the genetics of the skunk cabbage’s foul odour.Nature: Physicists turn lead into gold — for a fraction of a secondVideo: Scientists turn lead into goldNature: How skunk cabbages and other smelly plants brew their foul odourSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
