• How to transport antimatter — stick it on the back of a van

  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.

• NSF terminates huge number of grants and stops awarding new ones

  In this Podcast Extra, we examine recent developments US National Science Foundation, which has seen significant numbers of research grants terminated. In addition, there have been freezes on funding for new grants and any additional money to existing ones. We also discuss US President Donald Trump’s proposed budget for fiscal year 2026, which calls for disproportionately large cuts to federal science funding.News: Exclusive: NSF stops awarding new grants and funding existing onesNews: Trump proposes unprecedented budget cuts to US scienceNews: Are the Trump team’s actions affecting your research?

• Herring population loses migration 'memory' after heavy fishing

  00:46 How fishing activity altered the migration pattern of HerringSelective fishing of older herring has resulted in a large shift in the migration pattern of these fish, according to new research. For years, herring have visited sites on the south coast of Norway to spawn, but in 2020 a rapid shift was seen, with the fish instead visiting areas hundreds of kilometres to the north. Researchers have concluded that too many older fish have been removed from these waters, preventing the knowledge of the best spawning grounds being passed to younger, less experienced fish. This finding shows how human activity can affect animal migration, which could have serious consequences for the delicately balanced ecosystems built around them.Research article: Slotte et al.10:37 Research HighlightsArchaeologists have identified tools that the ancient Maya may have used for tattooing, and the self-assembling stable structures that may help ‘forever chemicals’ persist in nature.Research Highlight: Tattoo-making tools used by ancient Maya revealedResearch Highlight: ‘Forever’ molecules bunch themselves into cell-like structures13:02 How might AI companions affect users’ mental health?AI companions — apps where humans build relationships with computers — are hugely popular, with millions of people around the world using them.

• The dismantling of US science: can it survive Trump 2.0?

  In this episode:00:46 What will be left of US science after Trump 2.0?100 days into his term, President Donald Trump and his administration have already caused the biggest shakeup in modern scientific history, slashing funding, bringing large swathes of US research to a standstill and halting many clinical trials. But many fear these actions are just the beginning. We look at what the long-term impacts of these decisions might be for science in the United States and the world.Nature: Will US science survive Trump 2.0?13:42 Research HighlightsA distant planet that orbits two stars, at a right angle, and how fringe-lipped bats’ hearing helps them find palatable amphibians.Research Highlight: ‘Tatooine’-like planet orbits two stars ― but at a weird angleResearch Highlight: For these bats, eavesdropping is a valuable learnt skill16:07 Briefing ChatThe first skeletal evidence from bones that Roman gladiators fought lions, and scientists finally pinpoint the genes responsible for three of the pea traits studied by Gregor Mendel.BBC News: Bites on gladiator bones prove combat with lionNature: Century-old genetics mystery of Mendel’s peas finally solvedSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

• Audio long read: Do smartphones and social media really harm teens’ mental health?

  Research shows that, over the past two decades, rates of mental illness have been increasing in adolescents in many countries. While some scientists point to soaring use of smartphones and social media as a key driver for this trend, others say the evidence does not show a large effect of these technologies on teenagers’ psychological health.At the heart of the dispute is a large, complex and often conflicting body of research that different researchers interpret in different ways. This has left parents unsure what to do.This is an audio version of our Feature: Do smartphones and social media really harm teens’ mental health? Hosted on Acast.
