    01:04 A gel to safely transport proteinsA gel that encases proteins could be a new way to safely transport medicines without requiring them to be kept cold, according to new research. To test it, the team behind the work posted themselves a protein suspended in this gel, showing that it was perfectly preserved and retained its activity, despite being dropped in transit and exposed to varying temperatures. The researchers hope this gel will help overcome the need to freeze protein-based medicines, which can be expensive to do and difficult to maintain during transportation.

    11:24 Making a plastic biodegradableBy embedding a plastic with an engineered enzyme, researchers have developed a fully biodegradable material that can be broken down in a home compost heap. Plastic production often requires high temperatures, so the team adapted an enzyme to make it more able to withstand heat, while still able to break down a common plastic called PLA. They hope this enzyme-embedded plastic could replace current single-use items, helping to reduce the huge amount of waste produced each year.

    00:45 In situ editing of the gut microbiomeResearchers have developed a method to directly edit the genes of specific bacteria in the guts of live mice, something that has previously been difficult to accomplish due to the complexity of this environment. The tool was able to edit over 90% of an E. coli strain colonising mice guts, with other work showing the tool could be used to edit genes in pathogenic bacterial species and strains. It is hoped that with further research this technique could be adapted to work in humans, potentially altering bacteria associated with disease.

    08:46 How is bone health maintained during breastfeeding?During breastfeeding bones are stripped of calcium, while levels of oestrogen — which normally helps keep them healthy — drop off precipitously. This puts bones under tremendous stress, but why they don’t break down at this time has proved a mystery. Now, a team has identified a hormone produced in lactating mice that promotes the build up of bones, keeping them strong during milk production. Injecting this hormone into injured mice helped their bones heal faster, and the team hopes that their finding could ultimately help treat bone-weakening conditions like osteoporosis in humans.

    These frog 'saunas’ could help endangered species fight off a deadly fungus

    These frog 'saunas’ could help endangered species fight off a deadly fungus

    00:47 Searching for dark matter in black holesResearchers have been scanning the skies looking for black holes that formed at the very beginning of the Universe — one place where elusive and mysterious dark matter is thought to be located. If these black holes did contain dark matter, they would be especially massive and so researchers would be able to see the bending of light as they pass in front of stars. Such events would be rare, so to find them researchers trawled through a decades-long dataset. However, despite the large number of observations, the researchers didn't find many examples of these events and none that were long enough to show signs of much dark matter. So, the hunt for enigmatic material goes on.

    12:39 A simple, solution to tackle a deadly frog diseaseA simple ‘sauna’ built of bricks and a supermarket-bought greenhouse, can help frogs rid themselves of a devastating fungal disease, new research has shown. While options to prevent or treat infection are limited, the fungus that causes the disease chytridiomycosis has an achilles heel: it can’t survive at warm temperatures. A team in Australia used this knowledge to their advantage to develop saunas where frogs can warm themselves to clear an infection. Frogs who spent time in these hot environments were able to shake the fungus, and gained some immunity to subsequent infections. While this research only involved one type of frog, it offers some hope in tackling a deadly disease that has driven multiple species to extinction.

    Audio long read: How NASA astronauts are training to walk on the Moon in 2026

    Audio long read: How NASA astronauts are training to walk on the Moon in 2026

    In 2026, NASA aims to send humans back to the Moon's surface, as part of the Artemis III mission. In preparation, astronauts have been performing moonwalking simulations to ensure that they are able to make the most of their precious time on the lunar surface. In one dress rehearsal, a pair of astronauts took part in a training exercise in an Arizona volcanic field, working with a science team to practice doing geology work in difficult conditions designed to mimic some that will be experienced at the lunar south pole.

    Why ‘open source’ AIs could be anything but, the derailment risks of long freight trains, and breeding better wheat

    Why ‘open source’ AIs could be anything but, the derailment risks of long freight trains, and breeding better wheat

    00:31 How open are ‘open source’ AI systems?Many of the large language models powering AI systems are described as ‘open source’ but critics say this is a misnomer, with restricted access to code and training data preventing researchers from probing how these systems work. While the definition of open source in AI models is yet to be agreed, advocates say that ‘full’ openness is crucial in efforts to make AI accountable. New research has ranked the openness of different systems, showing that despite claims of ‘openness’ many companies still don’t disclose a lot of key information.
    Nature News: Not all ‘open source’ AI models are actually open: here’s a ranking
    06:12 Why longer freight trains are more prone to derailmentIn the US, there are no federal limits on the length of a freight train, but as companies look to run longer locomotives, questions arise about whether they are at greater risk of derailment. To find out, a team analysed data on accidents to predict the chances of longer trains coming off the tracks. They showed that replacing two 50-car freight trains with one 100-car train raises the odds of derailment by 11%, with the chances increasing the longer a train gets. While derailments are uncommon, this could change as economic pressures lead the freight industry to experiment with ever-longer trains.

    11:44 How historic wheat could give new traits to current cropsGenes from century-old wheat varieties could be used to breed useful traits into modern crops, helping them become more disease tolerant and reducing their need for fertiliser. Researchers sequenced the genomes of hundreds of historic varieties of wheat held in a seed collection from the 1920s and 30s, revealing a huge amount of genetic diversity unseen in modern crops. Plant breeding enabled the team to identify some of the areas of the plants’ genomes responsible for traits such as nutritional content and stress tolerance. It’s hoped that in the long term this knowledge could be used to improve modern varieties of wheat.

    How do fish know where a sound comes from? Scientists have an answer

    How do fish know where a sound comes from? Scientists have an answer

    00:46 How light touches are sensed during sex150 years after they were discovered, researchers have identified how specific nerve-cell structures on the penis and clitoris are activated. While these structures, called Krause corpuscles, are similar to touch-activated corpuscles found on people’s fingers and hands, there was little known about how they work, or their role in sex. Working in mice, a team found that Krause corpuscles in both male and females were activated when exposed to low-frequency vibrations and caused sexual behaviours like erections. The researchers hope that this work could help uncover the neurological basis underlying certain sexual dysfunctions.

    09:21 How fish detect the source of soundIt’s long been understood that fish can identify the direction a sound came from, but working out how they do it is a question that’s had scientists stumped for years. Now using a specialist setup, a team of researchers have demonstrated that some fish can independently detect two components of a soundwave — pressure and particle motion — and combine this information to identify where a sound comes from.

Perfect

I love reading Nature but the publisher has given me lots of issues, not paying $200 for zero customer service - so at this point I just listen

Belzurker ,

You lost me. This is anti science.

“It is clear that sex and gender exist beyond a simple binary. This is widely accepted by scientists and it is not something we will be debating in this podcast. But this whole area is full of complexity, and there are many discussions which need to be had around funding, inclusivity or research practices.”
