  • Dieting mosquitoes prevent disease

    10/02/2019 Duration: 05min

    Scientists have given a dieting drug made for humans to mosquitoes in order to curb their appetite. Researchers at the Rockefeller University in New York have worked through hundreds of thousands of molecule-receptor combinations to find the right one able to suppress the mosquito's hunger. As a result, mosquitoes were not interested in seeking a human blood meal and so this method could be used to help stop the spread of deadly diseases. Jenny Gracie spoke with Laura Duvall, lead author of a paper recently published in Cell, to find out why mosquitoes bite us in the first place... Like this podcast?

  • Hundreds of genes control the body clock

    07/02/2019 Duration: 06min

    If you are a night owl, getting up in the morning is something that you absolutely dread. On the other hand, morning people jump out of bed ready and chatty. Is this something hardwired? The answer's probably got a lot to do with the genes that influence your body clock. Chris Smith speaks to Samuel Jones from the University of Exeter to find out what the connection is.

  • Managing Cardiomyopathy

    06/02/2019 Duration: 03min

    Hypertrophic Cardiomyopathy is a genetic disease which causes the muscle of the heart to thicken. Left untreated, it can lead to heart failure, and it's quite common. But the therapies we have available at the moment treat only the symptoms and don't alter underlying disease course. Now new research from Harvard University, published in Science Translational Medicine, has identified the molecular clockwork that actually causes the condition, and they're testing a new drug that may help to stop it. Adam Murphy spoke to Chris Toepher to hear how... Like this podcast? Please help us by supporting the Naked Scientists

  • Improving carbon capture

    05/02/2019 Duration: 04min

    A new way to capture CO2 from factories or the atmosphere has been developed by researchers in the Oak Ridge National Laboratory, located in the United States of America. The new technology uses a different molecule to 'soak up' the CO2 and it is 24% more energy-efficient than the existing technologies. On top of it, the molecules can be reused up to a hundred times, meaning even more savings. This improvement on technology may prove a big step towards large-scale adoption of carbon capture, which could help slow down the effects of climate change.

  • Martian rock discovery surprises scientists

    04/02/2019 Duration: 05min

    There is a mountain located in the middle of a giant crater on Mars, but how it formed is still a bit of a puzzle for scientists. Investigations of the rocks below the surface of the crater have been helping piece together an answer. The Curiosity Rover currently on Mars has an advanced suite of scientific instruments able to carry out experiments on the Martian surface. Kevin Lewis is a planetary scientist from Johns Hopkins University, who along with help from colleagues, has been able to adapt some of the instruments to work in new ways. Jenny Gracie spoke with him to find out the rover's... Like this podcast? Please help us by supporting the Naked Scientists

  • Rocking adults to sleep

    01/02/2019 Duration: 05min

    Lack of sleep or poor sleep is a problem that affects 1 in 3 people in the UK and America. Insufficient sleep is not only a health issue, contributing to heart disease, diabetes and obesity, but also an economic one. There's the direct costs of treating sleep disorders and their numerous side effects, plus the costs associated with reduced productivity, time off work and injuries resulting from fatigue. With such a big problem at hand, we need to think of a solution outside the box. Mariana Campos spoke with Dr Aurore Perrault, formerly from the University of Geneva, now at the Sleep,...

  • Muscles really do have "memory"

    25/01/2019 Duration: 04min

    Nearly every cell in the body contains a part called the nucleus which houses the genetic information needed to function. Muscle cells are the largest cells in the body, so they often need multiple nuclei to meet high power demands. New research from the University Massachusetts at Amherst, supports the contradiction of a widely believed theory linking large cells and nuclei numbers. Jenny Gracie spoke with Professor Larry Schwartz to find out why the relationship may no longer be true... Like this podcast? Please help us by supporting the Naked Scientists

  • Whats inside your E-cigarette?

    21/01/2019 Duration: 04min

    It's common knowledge that smoking cigarettes is addictive, and this is because of the nicotine they contain. E-cigarettes are devices that heat up a liquid and produce an aerosol or spray which is then inhaled. If there's nicotine in the e-cigarette liquid then this gives a nicotine hit. In Australia, nicotine is classified as a poison, so it's illegal to sell e-cigarette liquids containing it, they have to instead be "nicotine free". But while studying the potential health impacts of e-cigarettes, scientists have found that, surprisingly, out of 10 "nicotine-free" e-cigarette liquids, or... Like this podcast?

  • Rare Pigment Fossilised in Teeth

    20/01/2019 Duration: 04min

    Brushing our teeth keeps them clean and free from debris, but back in medieval times, dental hygiene wasn't part of your daily routine. This means that scientists can look at the teeth of skeletons to reconstruct what food they might have munched on back then and find out more about their lifestyle. But recently a team of international scientists, lead from the Max Planck Institute for the Science of Human History in Jena, Germany, found something a little more peculiar fossilised in the teeth of a 1000 year old skeleton. Jenny Gracie spoke with Christina Warinner to unearth the mysterious... Like this podcast? Please help us by supporting the Naked Scientists

  • Opioid overdose detection via app

    18/01/2019 Duration: 06min

    Every day hundreds of people die when they accidentally overdose on opiate drugs, like heroin or morphine. These agents depress breathing, causing respiratory failure. But, if an opioid antidote is administered sufficiently quickly, then the situation can be reversed. And a team at the University of Washington have developed a system that turns a mobile phone into a sonar device that can monitor a person's breathing and then sound the alarm if something goes wrong. Chris Smith spoke with Jacob Sunshine, an anaesthesiologist and assistant professor at the University of Washington, to discuss... Like this podcast?

  • Sleep quality and Alzheimers disease

    15/01/2019 Duration: 04min

    One terrifying prediction is that, by mid-Century, up to 30% of adults will be affected by a form of dementia, chiefly Alzheimer's Disease. This happens when proteins called beta-amyloid, and tau, build up in the brain and damage nerve cells. But scientists think this begins to happen decades before a person develops Alzheimer's symptoms, meaning we might have an opportunity to intervene and change the course of the condition if we can tell who's affected sufficiently early. Now, researchers at Washington University in St Louis have discovered subtle changes in the patterns of brain waves we... Like this podcast? Please help us by supporting the Naked Scientists

  • Bio-inspired robot swarms

    21/12/2018 Duration: 05min

    Biological systems are able to create complex shapes and patterns, like the stripes of a zebra, the shape of your hand or the dynamic displays of a flock of birds. These shapes develop in an emergent and self-organised way, relying on just local interactions between individuals. In contrast, human designed technology is usually created by an external builder. But now, a team of roboticists and biologists have come together to design robot swarms that can self-organise into complex shapes. Hannah Laeverenz Schologelhofer spoke with Sabine Hauert from the Bristol Robotics Lab. Like this podcast? Please help us by supporting the Naked Scientists

  • Cheers to the liver!

    21/12/2018 Duration: 06min

    The Ancient Greeks understood that the liver was one of the most incredible organs humans possess when they wrote the cautionary tale of Zeus' punishment of Prometheus, in which poor Prometheus was tied to a rock where an eagle would eat his liver every day, but overnight it would regenerate and grow back, allowing his punishment to continue day after day. Now, in real life, the liver doesn't regenerate quite that quickly, but it is true that it has the ability to grow back and heal itself remarkably well. Georgia Mills spoke to liver scientist Auinash Kalsotra from the University of Illinois,... Like this podcast? Please help us by supporting the Naked Scientists

  • New test for cervical cancer

    20/12/2018 Duration: 05min

    Cervical cancer is one of the most common cancers affecting young women, and it's caused by a virus called Human Papilloma Virus, or HPV, which is spread through sexual contact. The virus causes the cells of the cervix to keeping growing excessively, which eventually damages their DNA, causing cancer. Testing for this cancer can be challenging: these days it involves using DNA tests to look for traces of the virus in a sample. But the viruses are very common, and only a small proportion of people carrying them will actually get cancer; so there are lots of false positives. Now researchers at... Like this podcast?

    Christmas is a wonderful time of year, but all of the additional transport and consumption adds up, and we are left with plenty of seasonal rubbish and greenhouse gases. So how can you cut down this Christmas? Georgia Mills is here to spoil all of the festive fun... Like this podcast? Please help us by supporting the Naked Scientists

  • Harnessing sunlight to clean water

    17/12/2018 Duration: 04min

    Clean water is something that we often take for granted, but making it can be a major technological and energy-intensive process. Now, thanks to a system developed by scientists at York University, Toronto, and MIT, there might be a way to do this much more cheaply in future. Hannah Laeverenz Schlogelhofer spoke with York researcher Thomas Cooper, about this new way of using sunlight to clean up water and produce superheated steam. Like this podcast?

  • 'Nano-tweezers' extract the contents of cells

    13/12/2018 Duration: 05min

    How can seemingly similar cells behave differently? This is a particularly important question when a small change means that a cell does not function properly and several diseases might be the result of these small changes at the single cell level. But a cell is a complex system, and some of the important molecules inside a cell exist in very small quantities that can be difficult to detect. To address this challenge, a new tool has been developed called 'nano-tweezers'. These tiny devices can extract individual molecules from inside cells.

  • Language development through childhood

    07/12/2018 Duration: 04min

    Language is all around us, and good language skills are important for getting on in life. But does being good in one language domain, like spelling, mean you'll be good in another, like grammar? And if your child is doing well with language as a toddler, will they still be doing well as a teenager? Recently, results have come out from a study 15 years in the making and Katie Haylor spoke to one of the authors, Rebecca Pearson from the University of Bristol. Like this podcast?
