Science In Action Folgen

A scheme in the US designed to prevent industrial espionage and the theft of intellectual property, is to be refocused after it was accused of unfairly targeting Chinese American scientists. We speak to Gang Chen, a professor from MIT who was falsely accused of financial crimes, and Holden Thorp Editor in Chief of the Journal Science who tells us why the ‘China Initiative’ is at odds with the reality of international scientific collaboration. And a huge study of farmed animals in China, from raccoon dogs to porcupines and Asian badgers, reveals that they carry a wide range of pathogens, including forms of avian flu and coronaviruses. Virologist Eddie Holmes from the University of Sydney, who was involved in the analysis, says these viruses may have the potential to jump species and infect humans – possibly leading to another pandemic.(Image: Students.

Messenger RNA-based vaccines have been used successfully to kick start the antibody production needed to fight Covid-19. Now the technology has been successfully used to encourage the growth of new bones to heal severe fractures. The technique seems to work far better than the current alternatives says Maastricht University’s Elizabeth Rosado Balmayor.Ivory smuggling continues to be a lucrative business for international criminal gangs, however, DNA techniques to trace where ivory seized by law enforcement authorities originates are now so accurate that individual animals can be pinpointed to within a few hundred miles. This says Samuel Wasser at the University of Washington, can be used as evidence against those ivory trafficking gangs.And we look at development in attempts to detect and weigh neutrinos, elusive subatomic particles essential to our understanding of the makeup of the universe. Physicist Diana Parno from Carnegie Mellon University takes us through the latest findings.Philologists have borrowed a statistical method from ecology to try and work out how much medieval romantic literature has been lost. The results seem to depend on which languages were involved, and like ecological systems, whether they were shared in isolated communities says Oxford University’s Katarzyna Kapitan(Photo: A doctor points to a x-ray of a woman's hand broken small metacarpal bone.

The Wuhan Institute of Virology has been at the centre of a controversy surrounding the origins of the virus which caused the Covid-19 pandemic. The work of the lab's previously obscure division looking at bat coronaviruses has been the subject of massive speculation and misinformation campaigns. Journalist and former biomedical scientist Jane Qiu has gained unique access to the lab. She has interviewed the staff there extensively and tells us what she found on her visits.And Tyler Starr from the Fred Hutchinson Institute in Seattle, has looked at a range of bat coronaviruses from around the world, looking to see whether they might have the capability to jump to humans in the future. He found many more than previously thought that either have or are potentially just a few mutations away from developing this ability.Nuclear fusion researchers at the 40-year-old Joint European Torus facility near Oxford in the UK for just the 3rd time in its long history, put fully-fledged nuclear fuel, a mixture of hydrogen isotopes, into the device, and got nuclear energy out – 59 megajoules. They used a tiny amount of fuel to make this in comparison with coal or gas.A survey of Arctic waters under ice near the North pole has revealed a colony of giant sponges, feeding on fossilised worms. Deep-Sea Ecologists Autun Purser at the Alfred-Wegener-Institut and Teresa Maria Morganti from the Max Planck Institute for Marine Microbiology tells us about the discovery.Presenter: Roland Pease Producer: Julian Siddle(Image: Getty Images)
