Science In Action Folgen

This year’s Atlantic hurricane season has seen a new record for severe storms says Climatologist Michael Mann. He says warming oceans are one of the drivers.And Australia has seen spring temperatures hit new highs. Climate scientist Sarah Perkins – Kirkpatrick says it’s all the more remarkable as weather patterns are currently in a cycle associated with cooler temperatures.Where exactly did SARS- COV-2 emerge from? That’s one of the questions for a WHO fact-finding mission to China looking into the origins of the Virus. Peter Daszak has worked with Chinese scientists for many years, looking for bat viruses with the potential to jump to humans. He tells us how the mission hopes to map out the event which led to the initial spread of the virus.And the Japanese Hayabusa2 space probe is due to return to earth. Masaki Fujimoto Deputy director of the Japanese Space Agency JAXA, tell us what to expect when a cargo of material from a distant asteroid lands in the Australian desert.

While developing new treatments drug companies usually release little useful information on how the clinical trials are progressing. However with the world’s attention on potential vaccines against Covid -19, the usually dull data on the progression of each trial step is subject to huge scrutiny. It doesn’t help to clarify things says epidemiologist Nicole Basta when that data raises questions about the rigour of the trial itself. This seems to be what happened with the latest Astra Zeneca, and Oxford University trial – where the best results were reportedly due to a mistake. The link between locust plagues and extreme weather was demonstrated once again when cyclone Gati hit Somalia – dumping 2 years worth of rain in just a few days. This creates a perfect environment for locusts to breed to plague proportions. And this will be the third time in as many years that cyclones will trigger such an effect says Keith Cressman from the UNFAO. However thanks to the previous recent locust plagues in East Africa the countries most in line for this returning locust storm are better prepared this time.A study of tree rings from Greater Mongolia suggests the region is now drying out rapidly, the past 20 years have been drier than the past thousand says climate scientist Hans Liderholm. This points to potential desertification in coming years.And the death of a scientific icon. The Arecibo observatory, featured in the films ‘Goldeneye’ and ‘Contact’, and responsible for the Nobel Prize winning detection of gravitational waves is facing demolition. Sitting in a crater in the jungles of Puerto Rico this 57 year old radio telescope dish has suffered severe storm damage and is in danger of collapse. Astronomer Anne Virkki, who works at the telescope and science writer Shannon Stirone explain its significance.(Image: Credit: Getty Images)Presenter: Roland Pease Producer: Julian Siddle

Tests on patients for up to 8 months following their infection with SARS- CoV-2 suggests an immune response can persist. Alessandro Sette and Daniela Weiskopf at the La Jolla Institute in California are optimistic this could mean vaccines would also confer long lasting immunity.An analysis of samples from Kenya’s blood banks by Sophie Uyoga at the KEMRI-Wellcome Research Programme reveals far more people in Kenya contracted the virus than was previously know. The figures mean Kenya has similar levels of infection to many European countries.And a study of mosquitoes by Louis Lambrechts of the Pasteur Institute in Paris reveals why Zika, a virus originating in Africa is much more prevalent in other parts of the world.We also look at the future of the Nile. Ethiopia is building a massive Dam which will have consequences for Sudan and Egypt who are reliant on the Nile’s waters says hydrologist Hisham Eldardiry from the University of Washington, Seattle.(Image: Credit: Getty Images)Presenter: Roland Pease Producer: Julian Siddle
