Each year 80,000 patients are hospitalised in the US for paracetamol overdose, the leading cause of liver damage in the US and Europe. The current treatment is effective at treating the liver damage, but because its efficacy is limited to being given within 8 hours since the overdose, scientists have been looking for alternative treatments. Melanie Jans-Singh spoke with clinical scientist Christof Gaunt, about the discovery of a new molecule that can treat the damage done by the paracetamol overdose to the liver... Like this podcast?

Face masks have their place, but what's really needed right now is a breath of fresh air and a dose of common sense to control Covid-19, as Chris Smith explains... Like this podcast? Please help us by supporting the Naked Scientists

New research has found a gene that looks to be the reason why rabbits, and perhaps all bouncing mammals hop. Using an unusual type of rabbit, called a sauteur d'Alfort, which doesn't hop, but runs on its front paws like a handstand, scientists have found a specific gene called RORB, that's missing in these rabbits. Defects in this gene may have damaging effects in all mammals though, not just rabbits. Adam Murphy spoke to Leif Andersson from Uppsala University about these bizarre bunnies... Like this podcast?

Spinosaurus was a dinosaur that was around 13 metres long, and looked a little like a T-Rex with the addition of a massive sail on its back. There's been much debate around how it lived; while it seems to be tied to the water, it's unclear how close those ties were. One theory suggests it was actually like a crocodile, living a pretty aquatic life. But new research points to features of its anatomy that suggest that it was a lot more like a giant, very toothy heron, waiting at the water's edge. Adam Murphy spoke to David Hone from Queen Mary University of London about the dino debate... Like this podcast? Please help us by supporting the Naked Scientists

We share our planet with microbes. Some do us harm, others do us good and are known as our microbiome. Plants also have a microbiome, and in a paper out recently, scientists working in a seed bank report how they got curious about what microbes could be stored away inside banked seeds. And by surveying seeds from just 1 type of plant, they found about 200 species of fungi. Katie Haylor spoke to study author Rowena Hill... Like this podcast?

In 1994, at DeGray Lake in the state of Arkansas in the USA, 29 bald eagles were found dead from a mysterious disease. Many more across the area have been found suffering from "Avian Vacuolar Myelinopathy", which causes holes in the brain and spinal cord, and erratic behaviour. Researchers now think they've cracked the mystery, as Eva Higginbotham heard from Timo Niedermeyer at Martin Luther University in Halle, Germany... Like this podcast?

Crohn's Disease is a type of inflammatory bowel disease (or IBD), where the immune system attacks and inflames bits of the intestines. It can cause diarrhea, pain, fatigue, and consequent disruptions to daily activities like school and work. There are treatments, but currently no cure. Now, scientists in the US have found that a fungus used industrially in foods like wine, cheese and cured meats - called Debaryomyces Hansenii - seems to be thriving in gut wounds in mice, and getting in the way of the wounds healing. And they think a similar thing is happening in the inflamed intestines of the... Like this podcast? Please help us by supporting the Naked Scientists

Fires of any scale tend to produce a certain amount of smoke - a variety of different particles including small bits of unburnt fuel, which eventually disperse into the atmosphere. And looking at data from satellites out in space, scientists in Israel have shown that smoke from the late 2019 / early 2020 Australian wildfires actually travelled up beyond the lower atmosphere (known as the troposphere) and into the stratosphere - that's above where clouds gather and planes tend to fly. Up here, these smoke particles stick around for longer, where they can absorb or scatter incoming energy from... Like this podcast? Please help us by supporting the Naked Scientists

Cone snails are a group of highly venomous marine snails. Their shells are beautiful, but they pack a powerful neurotoxic punch: some members of this family are so poisonous that they can easily kill a person. But one species of cone snail, called Conus imperialis, produces a very different reaction in the worms they hunt. This snail has a venom cocktail that includes pheromones: it uses similar chemicals to the ones the worms give off when mating. Why make a worm aphrodisiac? Phil Sansom spoke to Joshua Torres from the University of Copenhagen about these strange creatures... Like this podcast? Please help us by supporting the Naked Scientists

In recent years we've realised quite how bad a knock on the head can be for us, because the brain bobs about suspended in fluid inside our skulls. And if you move, or stop, the head suddenly, the brain cannons into the inside of the skull and can be injured. It's especially important in sports, but it's hard to study - and to develop effective safety equipment - for obvious reasons. But scientists have now discovered that something you commonly find in fridge door behaves in an uncannily similar way to your brain. Adam Murphy found out more... Like this podcast?
