  • How to transport antimatter — stick it on the back of a van
    2025/05/14
    00:46 An antimatter delivery van takes its first road trip

    Researchers 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.

    13:46 The mathematics of a near-miss between black holes

    Physicists 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.

  • NSF terminates huge number of grants and stops awarding new ones
    2025/05/12

    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.

  • Herring population loses migration 'memory' after heavy fishing
    2025/05/07
    00:46 How fishing activity altered the migration pattern of Herring

    Selective 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.

  • The dismantling of US science: can it survive Trump 2.0?
    2025/04/30

    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.

  • Audio long read: Do smartphones and social media really harm teens’ mental health?
    2025/04/25

    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.

  • A brand-new colour created by lasers, a pig-liver transplant trial gets the green light, and a nugget-sized chunk of lab-grown meat
    2025/04/23
    00:27 Five people see ‘olo’, a brand-new colour

    Using a laser system to activate specific eye cells, a team has allowed five study participants to perceive a vibrant blue-greenish hue well outside the natural range of colours seen by humans. Although the setup required to accomplish this feat is currently complicated, this finding could provide more understanding about how the brain perceives colour and could one day help boost the vision of people with colour blindness.

    08:30 US regulator greenlights pig-liver transplant trial

    The US Food and Drug Administration has approved the first trial to test whether genetically modified pig livers can be used safely to treat people with organ failure. In the initial phase of the trial, four people with severe liver failure will be temporarily connected to an external pig liver that will filter their blood. Participants will then be monitored for a year for safety and changes in liver function. The organs have been genetically modified to make them more compatible with humans.

    14:08: A chunk of lab-grown chicken

    Using a designer ‘circulatory system’, a team of researchers have created what they think is the largest piece of meat grown in the laboratory yet. One of the challenges to producing larger pieces of lab-grown meat has been providing cells with sufficient oxygen and nutrients, something the team’s new setup helps overcome. They used it to grow a chunk of chicken muscle about the size of a nugget, but multiple challenges remain before meat produced in this way could make it to market.

  • ‘Dark matter’, 'Big Bang' and ‘spin’: how physics terms can confuse researchers
    2025/04/22

    Categorizing things is central to science. And there are dozens of systems scientists have created to name everything from the trenches on the sea bed to the stars in the sky.


    But names have consequences. What’s in a name is a series exploring naming in science and how names impact the world. We look at whether the system of naming species remains in step with society, how the names of diseases can create stigma, and how the names chosen by scientists can help, or hinder, communication with the public.


    In episode three, we're looking at how the names chosen for concepts in physics can inadvertently send researchers down very specific research avenues while distracting them from others. In this podcast we hear five stories about the importance of names and how much can be lost in translation when physicists try and label the unknown.

  • What a trove of potato genomes reveals about the humble spud
    2025/04/16

    In this episode:




    00:46 A potato pangenome

    Researchers 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.
