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.
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
How good are you at finding your way from A to B? Humans throughout history have used all sorts of tools to get us to our destination – from a trusty map and compass to the instant directions on a smartphone sat nav. But CrowdScience listener Pam from Florida wants to know what happens when we leave the surface of the Earth – and try to navigate our way around space. Is there a North and South we can use to orientate ourselves? Which way is left if your nearest landmark is a million light-years away? And if you can’t tell which way is up, how do spacecraft know where they’re going? Presenter Anand Jagatia speaks to experts in an attempt to find his way through the tricky problem of intergalactic space navigation.

The trial of Paul Gicheru, a Kenyan lawyer accused of bribing prosecution witnesses of the International Criminal Court has started in The Hague. The arrest of Nigerian "super cop" Abba Kyari on drug-trafficking charges has laid bare the "public bickering" between two of Nigeria's law enforcement bodies, an analyst told the BBC. Commander Abba Kyari is accused of trying to recruit fellow officers into a drug plot. Plus we talk to Syriacus Buguzi, a Tanzanian medical doctor turned journalist, he tells us why he started the first science and technology newspaper in Swahili language.
A Sudanese politician who had been a member of the dissolved joint civilian-military government has been arrested.Some Chagossians evicted from the islands 50 years ago returned in a trip organised by the Mauritian government. The Mauritian flag has been raised for the very first time on the Chagos Islands in the Indian Ocean. Plus hear from Nigerian singer and songwriter Adekunle Gold, he explains how the pandemic encourage him to embrace the idea of change and develop a new musical style.
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 Qui 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.
And, Climate change and biodiversity loss are two of the biggest threats humanity has ever faced - and tackling them is going to take a whole lot of collaboration and putting others before ourselves. But are humans cut out for this level of cooperation? Or are we fundamentally too self-interested to work together for the common good?
Listener Divyesh is not very hopeful about all this, so he’s asked CrowdScience if humans have a “selfish gene” that dooms us to failure when trying to meet these challenges. He's worried that humans are destined by our evolution to consume ever more natural resources and destroy the environment in the process.
But while it's true that humans often act in our own interest, we also show high levels of cooperation and care. Could tapping into these beneficial behaviours help us solve our global problems? Marnie Chesterton goes on the hunt for the best ways to harness human nature for the good of planet Earth - from making sure the green choice is always the cheaper and easier option, to encouraging and nurturing our better, altruistic and collaborative sides.
We visit a rural mountain community in Spain to see the centuries-old system they have for sharing common resources; while in the city, we meet activists figuring out how to live a more community-spirited and sustainable urban life. And we speak to experts in evolution, ecology and psychology to find out what helps nudge us into greener habits.
