  • Sickle cell defeated malaria and opened up pastures new

    Sickle cell defeated malaria and opened up pastures new
    Jul 14 2026
    Malaria has been killing humans for at least fifteen thousand years, and our DNA still carries the scars. Ninety percent of the world's malaria cases are in Africa. But this isn't just a modern health crisis. It's written into our evolutionary history. New research from the University of Cambridge reveals that early humans actively avoided malaria hotspots across Africa for tens of thousands of years. The archaeological record is striking: mosquitoes thrived where people didn't live. Until something changed. Around fifteen thousand years ago, a genetic mutation emerged in West Africa: the...

  • Malaria in Africa

    Malaria in Africa
    May 20 2026
    Africa remains at the centre of the global malaria crisis. The continent accounts for around 95 percent of all malaria cases, placing immense strain on health systems and costing hundreds of thousands of lives each year. In 2023, there were an estimated 249 million cases globally, with the vast majority in sub-Saharan Africa. So why does malaria persist so strongly here? Like this podcast?

    Driven to End Malaria: World Malaria Day 2026
    Apr 26 2026
    A child dies from malaria roughly every minute. A stark reminder of why urgent action is still needed. "Driven to end malaria, now we can, now we must" is the theme of World Malaria Day on the 25th of April. This year also marks 25 years of the Johns Hopkins Malaria Research Institute, which has shaped modern malaria control strategies. In this episode, we hear from Ashley Birkett, Global Head of Bacterial and Parasitic Diseases at PATH Center for Vaccine Innovation and Access... Like this podcast?

  • Nocebos, and why the eyes of some species stay shut at birth

    Nocebos, and why the eyes of some species stay shut at birth
    Nov 30 2025
    This month, compelling evidence for why some species keep their eyes closed for sometimes several weeks after birth, scientists prove that the "nocebo" effect is more potent than a placebo, researchers report what happens when fish eggs and mouse sperm mix, the signals that cells use to measure the lengths of their telomeres, and some clever physics reveals the workings of Darwin's "warm little pond"...

  • Aspirin vs Clopidogrel: The blood thinner battle

    Aspirin vs Clopidogrel: The blood thinner battle
    Oct 3 2025
    Clots in our blood vessels can be responsible for very serious health problems such as strokes and heart attacks. To combat this, some people at risk of said health problems turn towards blood thinners to prevent this clotting, with the most common household blood thinner being aspirin. The issue with preventing clotting is, should you start to bleed, that bleeding is a lot tougher to stop. Now however, a new drug - clopidogrel - is being touted as coming with the same benefits of aspirin, but few of the drawbacks. To talk us through this matchup, we put in a call to the British Heart... Like this podcast? Please help us by supporting the Naked Scientists

    Public Success, Private Grief: remembering Peter Cowley
    Sep 23 2025
    Peter Cowley was an entrepreneur, angel investor, and for many years was the Naked Scientists technology commentator, a role he fell into by accident when we met one evening at an investment meeting. He became a good friend. But his life, in many respects, despite being incredibly successful, was also touched by great sadness: he lost two sons and struggled with alcohol for a time. But he came through it all and lived his life with energy, curiosity, and generosity... Like this podcast? Please help us by supporting the Naked Scientists

    Keeping humans healthy in orbit
    Sep 10 2025
    With only a few walls between an astronaut and a rapid death, what do we know about the various dangers to the human body during space travel? Chris Smith spoke with Mark Shelhamer, a professor of Otolaryngology - Head and Neck Surgery at John Hopkins Medical School - about which space hazards are deemed most pressing for our up-and-coming astronauts...
