  • Wetlands under attack
    Since its introduction four decades ago, Spartina alterniflora, a salt-water cordgrass from the USA, has been spreading along China’s coasts. Today, it covers nearly half of the country’s salt marshes. As the UN Biodiversity Conference COP 15 kicks off in China, we look at how this invasive plant species threatens native species in protected coastal wetlands. Featuring Yuan Lin, East China Normal University, and Qiang He, Fudan University. In January 2020, Barney Graham and Jason McLellan teamed up to engineer a coronavirus spike protein that now powers the COVID-19 vaccines for Moderna, Pfizer, Johnson & Johnson and Novavax. They discuss their work, a next-generation vaccine using chicken eggs, and the future of pandemic preparedness. Also, a recent Nature survey reveals the extent of abuse against scientists who speak about COVID-19 publicly. Deepti Gurdasani, Queen Mary University of London, shares her experiences of trolling and online abuse and discusses the implications for academia and scientific discourse going forward. And Tom Scott explains how his team uses novel robots and sensors to go into and create 3D digital radiation maps of the Chornobyl Nuclear Power Plant and surrounding areas.

  • Youngest rock samples from the moon
    In December 2020, China's Chang'e-5 mission returned to earth carrying rock samples collected from the moon – the first lunar samples to be collected since the American Apollo and Luna missions to the moon in the 1970s. Laboratory analysis has revealed that these are the youngest samples of rocks to be collected from the moon. Lunar geologist Katherine Joy explains what this tells us about the moon’s volcanic past. Also on the programme, a recent study reveals that the hepatitis B virus has been infecting humans for at least 10,000 years. Denise Kühnert from the Max Planck Institute for the Science of Human History shares what the evolution of the virus tells us about human evolution, as well as the rise and fall of civilisations. In the wake of Cyclone Shaheen, we also speak to Princeton University’s Ning Lin about how climate modelling can help us predict tropical storms in the Arabian Sea, and Fredi Otto joins us to discuss the 2021 Nobel Prizes for Science.

  • Drug resistant malaria found in East Africa
    Since their discovery in the 1970s, artemisinin-based drugs have become the mainstay of treatment for malaria caused by the Plasmodium falciparum parasite. Researchers have identified artemisinin-resistant malaria parasites in Southeast Asia since the early 2000s, but now, there is evidence of resistance in Rwanda and Uganda. Dr Betty Balikagala of Juntendo University tells us how this resistance developed and what it means for managing malaria in Africa, which carries the greatest burden of malaria cases and deaths worldwide. We hear from some of the scientists from COVID Moonshot, a non-profit, open-science consortium which has just received key funding to develop affordable antivirals to stop SARS-CoV-2 in its tracks. Also on the programme, Dr Rakesh Ghosh from the University of California, San Francisco tells us how air pollution is contributing to 6 million preterm births globally each year, and Dr Catherine Nakalembe of the University of Maryland and Africa Lead for NASA Harvest returns to the programme as NASA/USGS launches Landsat 9.

  • New evidence for Sars-CoV-2’s origin in bats
    Researchers studying bats in Northern Laos have found evidence that brings us closer than ever to understanding the origin of Covid-19. Since the beginning of the coronavirus pandemic scientists have tried to pin-point the exact origin of Sars-CoV-2. But recent evidence from the Institut Pasteur has identified several novel coronaviruses with similarities to the current coronavirus in bats. Professor Marc Eliot spoke to Roland Pease about how this research could give us a better idea where Covid-19 came from. Could an oral Covid-19 treatment be available soon? Daria Hazuda, responsible for infectious disease and bacteria research at MSD tells us about their clinical trials for an oral antiviral drug that could combat Covid-19: Molnupiravir. Early Diagnosis of Alzheimer's Roland Pease travels to Bath to meet scientists who may have developed a way to diagnose Alzheimer's in the earlier stages of the disease. Dr George Stothart, has led the team from Bath university in the development of this simple 2 minute test. Inducing Earthquakes Scientists are experimenting with artificially managing earthquakes by injecting fluid into fault lines. Professor Derek Elsworth at Pennsylvania State University explains his research into how these induced earthquakes can be more tightly controlled.

  • Ebola can remain dormant for five years
    An international team of researchers has discovered that an outbreak of Ebola in Guinea in February this year was the result of re-activated Ebola virus in someone who’d been infected at least five years ago during the earlier large Ebola epidemic that swept through Guinea, Sierra Leone and Liberia. This means the virus can remain dormant in some Ebola survivors for five years or more. Virologists Alpha Kabinet Keita and Robert Garry talk to Roland Pease about the research and its implications. Also in the programme: The eruption of lavas from Iceland’s newest volcano Fagradalsfjall continues six months on. Geochemist Ed Marshall tells us how he gets up close to sample the molten rock with a long scoop and a bucket of water, and what he’s learning about this remarkable eruption. NASA’s Katie Stack Morgan updates Science in Action on the Perseverance rover’s successful sampling of rocks from Jezero crater on the planet Mars. When the specimens are eventually returned to Earth, she says they may turn out to contain tiny samples of Mars’ water and atmosphere from early in the Red Planet’s history.
