Plastics are useful but notoriously hard to recycle back into their component chemicals, which limits what else we can do with them. Now, scientists in the US have developed a new catalyst that can break apart common plastics and turn them into chemicals that can be used to make other products. Cambridge University's Taylor Uekert works on ways to deal with plastic waste and she talked Katie Haylo...

We've heard news that Morrisons, Waitrose and John Lewis' own brand Christmas products will not contain glitter this year. And now, scientists at Anglia Ruskin University have looked at making little ponds in the lab with river water and sediment. Katie Haylor heard from lead author Danielle Green, who explained that all the glitters they tested had an impact on the plants and algae in these ponds...

If you've been paying attention to the news in recent times, you'll be very familiar by now with graphs: COVID rates, infection rates, data are being displayed in a plethora of ways. But there are, as the old saying Mark Twain made popular goes "lies; damn lies and statistics", so are there any "gotchas" we should look out for when someone shows us a graph? Adam Murphy caught up with Nira Chamberl...

Britain recently began a diplomatic campaign to draw up new rules for responsible behaviour in space; essentially it's a "don't litter" policy intended to reduce the threat posed by decades of irresponsible dumping in orbit. But what's the scale of the problem of space littering, and how might things go wrong? Adam Murphy spoke to John Zarnecki, emeritus professor of Space Sciences at the Open Uni...

On the 28th September, Boris Johnson committed to increasing the area of protected land in the UK to 30% by 2030. This announcement was made at a virtual UN event, where the prime minister, alongside upwards of 60 other world leaders, signed up to a pledge to tackle the world's chronic loss of biodiversity. Sir David Attenborough addressed the event too, imploring world leaders to do more to prote...

How do bees recognise who's a bona fide member of the nest and who is an impostor? It turns out that it's down to the bacteria they carry inside them... Eva Higginbotham heard how Cassondra Vernier at Washington University in St Louis has figured it out with her colleague Yehuda Ben-Shahar... Like this podcast?

For decades, astronomers have been scouring the skies looking for signs and signals that appear to be from creatures on other planets. But discussions on this topic invariably stray into science fiction and conjure images of 'little green men'. What might complex alien life really look like? That's the subject of The Zoologist's Guide to the Galaxy: What Animals on Earth Reveal about Aliens - and...

Covid-19 is forcing educators to re-think centuries of teaching traditions and develop new ways to provide a rich but safe student experience. Jim Gazzard leads Cambridge University's Institute of Continuing Education (ICE). He joined palaeoanthropologist Lee Berger and Theo Bloom to speak with Chris Smith about how adult education and training are evolving rapidly... Like this podcast? Please hel...

On October 8th, about 15,000 students will return for the new academic year at Cambridge University. Other UK institutions have seen outbreaks and quarantine measures en-masse as Covid has ripped though university campuses. Cambridge Vice Chancellor Stephen Toope spoke with Chris Smith to discuss whether the student experience can be preserved at Cambridge in the face of measures required to contr...

Welcome to the end of the universe. Which one will we get? Will the life drain slowly from thousands of cold, dead galaxies; or will the stars get ripped apart by a wave of strange new matter? That's the subject of a new book by astrophysicist Katie Mack, "The End of Everything". And be warned, some of the catastrophes she described to Phil Sansom make the coronavirus look like a walk in the park....

Everyone loves magic. But does that extend to animals? You might have seen videos online of people performing tricks to animals, and the animals being hugely entertained by it, but do they understand what's going on. That's the idea put forth by researchers from the University of Cambridge. Adam Murphy spoke to Elias Garcia-Pelegrin about what magic tricks might be teach us about the animals aroun...

Myotonic dystrophy type 1 is a debilitating genetic disease that causes muscle weakness and wasting, amongst other problems, and there's currently no cure. It causes a toxic form of the chemical RNA - a genetic messenger molecule similar to DNA - to build up and clog up other important processes inside cells. Now, scientists at the University of California San Diego have used gene editing to rever...

People everywhere are clinging to the hope that there'll soon be a coronavirus vaccine. That aspiration suffered a setback last week when AstraZeneca announced the suspension of its trial of the Covid-19 vaccine it's developing. So how are decisions to start and stop clinical trials made, and what's the present trajectory for a coronavirus vaccine? Chris Smith asked Gordon Dougan, who's overseen t...

Virologist Dr Chris Smith joins Radio New Zealand National's Kim Hill for a Covid-19 update covering why AstraZeneca and Oxford University's coronavirus vaccine trial was halted and how vaccine side effects are investigated, why Boris Johnson has launched his Covid moonshot, signs that vapers are at higher risk of Covid-19, long term immunity to coronavirus infection or vaccination, and the bradyk...

Drink driving is one of the biggest killers on our roads. Brian Suffoletto is an A&E doctor in the US where he's spent the past 15 years developing digital interventions to stop people drinking and driving. Lately he's been working on a system that uses a smartphone to analyse the way a person walks to pick up on subtle giveaways that they're over the limit. Katie Haylor heard how it works......

PTSD is a disease that may occur after experiencing trauma, often characterised by the involuntary reliving of particularly painful memories. About 1 in 3 people who experience trauma will develop PTSD, but it's unclear why some people develop it and others don't. New research out of the University of Basel has shown that a genetic component may help explain why some people are more susceptible, a...

Getting cold won't just make your hair stand up, it may also make it grow. Yulia Shwartz at Harvard University and her colleagues have found that the nerves that give us goose pimples also send a message to the cells in the follicles that produce hairs, making them grow. It explains the prolific winter coat that some animals grow in the cold. Cambridge dermatologist Jane Sterling took Chris Smith...

Giant pandas, which for decades were endangered, finally shed the status in 2016 thanks to huge conservation efforts. But scientists have been warning that their reserves aren't well designed for the ecosystem as a whole - and now a group of zoologists have found that even though panda numbers have gone up since the 60s, big carnivores like leopards have almost disappeared. Bill McShea from the Sm...
