Darwin dumped from Indian classrooms

India is at the centre of much of the discussion on this week’s episode of Science In Action. We hear about how a proposal to scrap Darwinian evolution from Indian secondary schools has led to signatures from thousands of scientists. Dr Vineeta Bal, Researcher at the National University of Immunology, is one of the signatories on a petition against the proposed changes. We spoke to her about why she is against them.Also in India, a new Sars-Cov-2 variant, named XBBX.16 is being studied by epidemiologists in the country. Dr Rajesh Karyakarte, professor of microbiology at BJ Government Medical College, Pune, India, is behind the study. Further study of the variant has been looked into by Kei Sato, professor of Systems Virology at the University of Tokyo. Kei has been mapping how new variants could cause us problems, ahead of them doing so. This kind of forward planning is something praised by Paul Bienaisz, Professor of Virology at The Rockefeller university. We talk to him about how vital this kind of work still is, even if many of us have confined the about the SARS-CoV-2 pandemic to memory. Lastly, we hear from Dr Usama Kadri, Senior Lecturer in Applied Mathematics at Cardiff University who has looked at how we might be able to use a novel bit of technology of underwater technology (called hydrophones), often used for animal conservation, to be able to detect earthquakes in the deep sea.

The truth about the Sudan biolab

Khartoum’s National Public Health Laboratory has been caught up in the ongoing conflict in Sudan. Dr Maysoon Dahab and Dr Ayman Ahmed explain the situation and why health labs are often targeted in conflicts.Virus hunters have used artificial intelligence to discover more than 180,000 new viruses. Professor Eddie Holmes and Dr Mang Shi tell Roland how AI is completely transforming the field of viral discovery.Experts have forecasted a return to El Niño conditions later this year, which could bring with it extreme weather events. Dr Emily Becker explains how the predictions are made and the global impact of a strong El Niño.And from future to historical weather – Roland talks to Professor Ed Hawkins about the powerful Storm Ulysses of 1903, and how it can help us better understand storms today.Presenter: Roland Pease Producer: Roland Pease Assistant Producer: Sophie Ormiston

Africa moves towards creating and manufacturing its own vaccines

The pandemic showed Africa at the back of the global queue when it came to vaccines. That should never happen again if plans being debated in Cape Town this week go ahead. Roland talks to Seanette Wilson of South Africa's Biovac.Also in the programme: life finds a way on plastic floating in the ocean; Greenland rock dust as a global fertiliser; and designing proteins from scratch.Image Credit: Robert Bonet/NurPhoto via Getty ImagesPresenter: Roland Pease Producer: Roland Pease Assistant Producer: Sophie Ormiston

Bird flu: The global threat

H5N1, a highly pathogenic avian flu is racing across the world, and has infected multiple species, including wild and farmed birds, and mammals from cats to sea lions. What can be done to control it? Roland Pease talks to global experts about the dangers to animal and human health, and about the measures to bring the outbreak under control.Producer: Roland Pease Assistant producer: Sophie Ormiston(Photo: A government worker examines chicks for signs of bird flu infection at a poultry farm in Darul Imarah in Indonesia's Aceh province.

Chasing tornados in the American mid-West

Chasing tornados in the American mid-West – scientists are trying to learn the maximum from the tornado outbreaks currently in America. Professor Karen Kosiba calls us from a radar truck studying the storms, and Professor John Allen explains the energy powering them. From the weather of today to the skies of 800 years ago... Dr Sébastien Guillet reveals how lunar observations by medieval monks are helping untangle the connection between historic eruptions and climate. Finally, we go back even further in time to the Bronze Age with Professor Elisa Guerra-Doce – to find out what drugs our ancestors were into. Image credit: Getty Images / Michael B.

Gene editing breakthrough

We look at a gene editing breakthrough, a new technique to correct genetic errors in sick patients. Roland speaks to Professor David Liu to learn about the base editing technology.Also, we look into the complex causes of last year's post-pandemic spike in child hepatitis. Professor Judy Breuer and her colleagues may have found an explanation behind the unexpected outbreak.And the James Webb Space Telescope continues to seek out the secrets of our universe. Professor Beth Biller and Dr Elsa Ducrot have the details on the atmospheres of two very distant, and very different, exoplanets.Plus, how to get sober – for mice. Professor Steven Kliewer explains how certain mammals have evolved to deal with the intoxicating effects of ethanol.

Animals at the Wuhan Market

DNA has revealed potential animal COVID carriers at the Wuhan market, but what does that tell us about the start of the pandemic? Roland talks to two of the experts behind the new analysis: Dr Florence Débarre and Professor Eddie Holmes.Also, we look into Europe’s grand new space ambitions. ESA director general Josef Aschbacher gives Roland the details of the space agency’s out-of-this-world plans.And Beethoven's last DNA: a hairy story of his family and genetic afflictions. Dr Tristan Begg shares how the composer’s tresses unlocked new information about his life and death.Image credit: Eddie HolmesProducer: Roland Pease Assistant producer: Sophie Ormiston

Return of Cyclone Freddy

34 days after it first formed at the far end of the Indian Ocean, record-breaking Cyclone Freddy made a repeat landfall on Mozambique as well as passing over Malawi, causing extensive damage and loss of life. Climate scientists Liz Stephens and Izidine Pinto join Roland to give an update on the destruction and explain how Cyclone Freddy kept going for an exceptionally long time.At the Third International Human Genome Summit in London last week, Professor Katsuhiko Hayashi announced he had created baby mice from eggs formed by male mouse cells. Dr Nitzan Gonen explains the underlying science, whilst Professor Hank Greely discusses the ethics and future prospects.And from one rodent story to another, SARS-CoV-2 has been detected in brown rats scurrying around New York sewers. Dr Thomas DeLiberto from the US Department of Agriculture gives Roland the details.Image credit: Jack McBrams/Getty ImagesProducer: Roland Pease Assistant Producer: Sophie Ormiston

Human Genome Editing - Promise and Peril

Human Genome Editing: The team meet experts at the Human Genome Editing Summit in London, seeking to cure genetic disease and ensure that it's safe and available to all. Roland Pease hears from Victoria Gray, the first person to be cured of the debilitating and life-shortening disease sickle cell anaemia by gene editing, and from the scientists making it possible. Also, the prospect of work to attempt gene rescue in fetuses before they are born. But the technology is expensive and complex – the question troubling the participants is to ensure people across the world can benefit from it, not just the rich and privileged. And what are the limitations of gene editing? Can it be made more effective, safer? And what of gene edits that will be inherited by future generations?

Drought worsens in East Africa

The long rains of East Africa are forecast to fail again, for the third year running, precipitating a food crisis affecting millions. Science In Action explores the science of the drought, hears about new methods improving forecasts, and what is unusual about the region that makes it so vulnerable.When we think of helium, for many of us balloons and squeaky voices come to mind. But the noble gas is critical for many aspects of modern life – and we’re facing a global shortage. Dr Annie Cheng and her colleagues at the University of Oxford are attempting to solve this by creating a model that has the potential to locate previously untapped reservoirs.Image by Gerald Anderson/Anadolu Agency via Getty ImagesProducer: Roland Pease Assistant Producer: Sophie Ormiston
