When two atoms join together, the laws of physics tell us that a large amount of energy will be released, but the experiments performed so far by scientists to achieve nuclear fusion have always yielded a lot less energy than the inputs. This week, the Lawrence Livermore National Laboratory in California, which uses an approach called 'inertial confinement fusion', announced that they achieved a huge improvement in the record energy yield from a fusion experiment. Iacopo Russo heard from Debbie Callahan, a lead researcher on the project. Like this podcast? Please help us by supporting the Naked Scientists

The first part of understanding a new language is working out where one word stops and the next word starts out of a string of syllables. Researchers at ELTE University in Hungary have been looking at how dogs' brains respond to language to figure out if they can recognise words, as Sally Le Page found out from author Marianna Boros...

We talk a lot about proteins on this programme - what they do, how they work - but have you ever wondered what they sound like? A group of scientists at the National University of Singapore have been turning proteins into pieces of music, as Sally Le Page heard from author, Peng Zhang. Like this podcast?

Antibiotics are such an important part of modern medicine but their effectiveness has been waning in the last few decades as certain bacteria, so called superbugs, have become resistant to multiple common antibiotics, leading to the UN declaring that antimicrobial resistance is one of the top 10 global public health threats facing humanity. To tackle this issue, new approaches are needed and as new strains of antibiotics are hard to come by, one option is to modify existing antibiotics to make them more effective. Verner Viisainen spoke to Jennifer Payne from Monash University to find out... Like this podcast? Please help us by supporting the Naked Scientists

Have you ever noticed that you take one particular walking route to the shops, only to take a completely different route on the way back? If so, you might not be alone...based on recent paper published in Nature Computational Science, this is more common than you might think and could be because our brains try to always take the pointiest, not necessarily the fastest, route to their destination.

The Earthshot Prize is an ambitious environmental program created by His Royal Highness Prince William to find and develop solutions for the climate emergency. This year's prizes were awarded last month at a ceremony in London. The prize for the Fix Our Climate category went to company Enapter, which developed a technology called "AEM hydrogen electrolyser". Iacopo Russo heard from Enapter's co-founder Jan-Justus Schmidt, and from Cambridge University engineering professor David Cebon, to find out firstly what an electrolyser is and more importantly what hydrogen can do for us in a sustainable...

"Test! Test! Test!" was the instruction from the World Health Organisation when the Covid-19 pandemic began to take hold around the world. Now scientists at MIT think they might have a solution, both for this pandemic and future ones: they've developed a sensor system comprising a fibre optic to which a special coating is applied that can recognise specific viruses. When it does so, it emits light of a specific colour, signalling a detection. Like this podcast? Please help us by supporting the Naked Scientists

New research published this week has turned what we know about Alzheimer's disease progression on its head. Instead of the disease gradually spreading through the brain causing symptoms to get worse, the study found progression relied more on how quickly the number of disease-associated proteins increased in individual brain regions. Julia Ravey heard from Cambridge University's Georg Meisl, the study's author, on how this may impact future treatments. Like this podcast? Please help us by supporting the Naked Scientists

Wild water swimming is becoming ever more popular and, according to a new study published recently in Cell Reports Medicine, combining dips in cold water with time in a hot sauna could have potential health benefits.
