Wed, 13 May 2026 - 21min - 965 - Audio long read: The air is full of DNA — here’s what scientists are using it for
Although scientists have long been able to gather DNA from water and soil, it's only recently that they've started to see the air as a source of genetic information.
Airborne DNA is already being used to monitor individual species, but researchers hope its abundance could have multiple uses, including judging the success of conservation efforts or attacks with biological weapons.
However, there remains much to understand, such as how far DNA travels in the air, and the ethics involved in the potential identification of a person's genetic information.

Wed, 14 Jan 2026 - 21min - 928 - A mysterious ancient fingerprint and a lemon-shaped planet — the stories you’ve missed
00:54 Turning an undersea cable into a seismic detector
Researchers 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 detector
04:17 The origin of an ancient boat
Chemical analysis of the caulking found on the wood an ancient boat has helped researchers identify the origins of the vessel, that sank off the coast of Denmark 2,400 years ago. The team’s analysis suggests it voyaged from much farther away that had been thought — perhaps coming from the Baltic Sea region. The team also found a fingerprint left in the caulk, although who it belonged to is unknown.

08:29 How heating up helps some plants pollinate
Some plants called cycads (Zamia spp.) heat up to attract the beetles that pollinate them. These beetles have heat-seeking sensors in their antennae, which they use locate the plants. Male cycads warm up around 3 hours before females, meaning that beetles head to them before first carrying pollen over to the females.

Thu, 01 Jan 2026 - 11min - 926 - Audio long read: Will blockbuster obesity drugs revolutionize addiction treatment?
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 are excited, as no truly new class of addiction medicine has won approval from regulators in decades.

00:40 What a trove of potato genomes reveals about the humble spud
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.

Wed, 17 Dec 2025 - 42min - 922 - Neanderthals mastered fire — 400,000 years ago
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.

The 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.

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.

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 thin Martian atmosphere.

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 the long-term safety of this strategy, the team hope it could offer a way to non-invasively deliver other large-molecule drugs into the body.

The human brain responds in a similar way to both familiar and unfamiliar languages, but there are some key differences, according to new research — a finding that may explain why learning a language can be difficult. A study looking involving 34 people showed that listening to an unfamiliar language triggers similar neural activity to listening to their native tongue. The finding implies that human speech triggers a common reaction in the brain regardless of understanding. However, there were subtle differences when listening to a known language that may help explain how people actually understand words.

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.

An ‘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.

Researchers 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.

In April, Robert F. Kennedy Jr held a press conference about rising diagnoses of autism, and said he would soon be announcing a study to find the responsible agent. Although Kennedy said that environmental factors are the main cause of autism, research has shown that genetics plays a bigger part. Also, the rise in prevalence, many researchers say, is
predominantly caused by an increase in diagnoses rather than a true rise in the underlying symptoms and traits.
Although the US National Institutes of Health (NIH) announced a US$50 million to fund studies on the causes of autism, many researchers were dismayed that these developments seemed to ignore decades of work on the well-documented rise in diagnoses and on causes of the developmental condition.

Using AI tools may make you more likely to cheat at tasks like tax reporting, according to a new study. Using a well-studied test of honesty, researchers looked to see if people were more likely to engage in unethical behaviour if given the option of delegating it to an AI. Including AIs seemed to increase the chance that someone would be dishonest, which raises concerns about the impacts of these tools on ethics.

Wed, 17 Sep 2025 - 35min - 904 - Detecting gravitational waves
In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time, known as gravitational waves. These waves were produced by the final spiral of two orbiting black holes that smashed into each other, sending ripples across the Universe.
In this podcast, Benjamin Thompson speaks to Cole Miller from the University of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 1916.

Major energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature. Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have been “virtually impossible” without climate change, and that nearly a quarter of the heatwaves recorded from 2000 to 2023 can be directly linked to the greenhouse-gas emissions from individual energy giants.

Wed, 10 Sep 2025 - 36min - 902 - Research misconduct: how the scientific community is fighting back
In 2016, Brian Wansink wrote a blog post that prompted scientific sleuths to investigate his work. They found evidence of data manipulation, and, after several news articles and two investigations by his institution, he would found to have committed misconduct, as defined by Cornell University. His work had been used to inform US policy around food, much of which has now been thrown into question.
Cases like this are rare, but science is not immune to misconduct. The rise in 'paper mills' — organisations that produce questionable or fake papers that they sell authorships on — has led some to worry that misconduct is on the rise and that a proportion of the scientific literature cannot be trusted.
In episode two of Self Correction, we explore how researchers are responding to the problem of research misconduct. We discuss how difficult it is to determine the prevalence of misconduct, and how sleuths, journalists and research integrity institutions are fighting back.

Fri, 05 Sep 2025 - 10min - 900 - Two ants, two species, one mother
00:45 The ant queen that can produce two different species
Researchers have made an unusual observation that appears at odds with biology: an ant, known as the Iberian Harvester Ant can produce offspring of two completely different species. Many ants need to mate with other species to produce workers that are a genetic mix of the two, known as hybrids. But in Sicily, a team found hybrid worker ants but no trace of the father. They suggest that the one species present, Messor ibericus, is able to lay its own eggs, but also eggs of another species, Messor structor. These offspring can then mate to produce the hybrid workers. This strategy conflicts with several conventional definitions of what a species is, which may prompt a rethink of these already blurry concepts.

Researchers have discovered that steel truss bridges possess a number of mechanisms that make them resilient to collapse, even after damage. Steel truss bridges are a common kind of bridge, but many are ageing and under increased pressure due to climate change and increased vehicle loads. To understand how damage affects these bridges a team of engineers built a scale replica of a bridge section and monitored how it coped when different sections were cut. They found six distinct resistance mechanisms that allowed the bridge to continue carrying heavy loads even with the damaged sections. They hope these data will help fortify existing bridges and inform the design of future bridges to help prevent catastrophic collapse.

Researchers have used electrochemistry to increase the rates of nuclear fusion reactions in a desktop reactor. Fusion energy promises abundant clean energy, but fusion events are rare, hindering progress. Now, inspired by the controversial claim of cold fusion, researchers used electrochemistry to get palladium to absorb more deuterium ions, that are used in fusion. When a beam of deuterium was fired at the deuterium-filled palladium, they saw a 15% increase in fusion events. They did not get more energy than they put in, but the authors believe this is a step towards enhancing fusion energy and shows the promise of electrochemical techniques.

Many harmless animals mimic dangerous ones to avoid being eaten, but often this fakery is inaccurate. To help explain why evolution sometimes favours imperfect mimicry, a team 3D printed a range of imaginary insects. The novel creatures were designed to mimic wasps with varying degrees of accuracy and the team then presented these models to different predators. They showed that while birds were hard to fool, invertebrate predators were less able to discern between the mimics and accurate wasp models. The results suggest that predator perception plays a key role in the level of accuracy needed to fool them and may help explain the existence of inaccurate mimics in nature.

Fri, 13 Jun 2025 - 9min - 882 - This stretchy neural implant grows with an axolotl's brain
00:45 A flexible neural-implant that grows with the brain
Researchers 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.

15:30 An AI-based way to repair damaged paintings
By 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. It was successfully tested on an oil painting, fixing a large number of damaged areas in only a few hours. This could offer a significant speed-boost to painting restoration, which can often take months, or even years.

In this Podcast Extra, we examine President Donald Trump's calls for NASA to land humans on Mars. Although the White House has proposed spending some US$1 billion in 2026 on Mars plans, critics say the final cost will likely be hundreds of billions of dollars spread over a number of years.
This call comes amidst plans to drastically reduce NASA's funding, and the proposed cancelling of dozens of the space agency's missions, including projects to study Earth, Mars and Venus.

Fri, 06 Jun 2025 - 11min - 880 - Male mice can grow female organs — if their mothers lack iron
00:45 Iron’s role in mice sex determination
Iron 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.

08:51 The role of small-scale fishers in sustainability
The 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. The people behind the initiative hope that these data can help give a voice to small-scale fishers as people look for ways to feed the world sustainably.

With the world looking likely to blow past the temperature targets laid out in the 2015 Paris climate agreement, a growing number of voices are saying that carbon removal technologies will be necessary if humanity is to achieve its long-term climate goals. If these approaches succeed, they could help nations and corporations to meet their climate commitments — and help the world to halt global warming.
However, questions remain about the financial viability of these technologies, and whether they can live up to the hype.

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.

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.

Mon, 12 May 2025 - 11min - 874 - Herring population loses migration 'memory' after heavy fishing
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.
