This week has seen a huge surge in Covid- 19 in India leading to concern of a "double mutant" variant, but what do we know about this B.1.617 as it is otherwise known. It was first described in October and is now in other countries including the UK. Virologist Dr Muge Cevik looks at the emerging evidence around vaccines and new variants. Climate change threatens coffee crops so it's exciting to know that researchers have found an ancient coffee variety that is drought resistant and can tolerate higher temperatures than the highly prized Arabica coffee used to make your latte - but it wasn't easy to find. In Sierra Leone Daniel Sarmu spent 4 years searching for it and Dr Aaron Davis from Kew helped to track it down using historic samples from the Herbarium at the Royal Botanic Gardens.Clothes moths do enormous damage to our jumpers and carpets, Marnie finds out how best to protect your clothes. And we hear from Mark Miodownik about the right to repair.

The story of what we understand about the rare cases of blood clots associated with certain Covid-19 vaccines is constantly evolving. In today’s programme Professor Beverley Hunt looks at the emerging evidence.How have the restrictions due to Covid 19 affected how we grieve? Professor Claire White, an expert in grief and mourning, is investigating what it means to the grief process when the traditional ways of acknowledging death are changed.Sascha Fruholz has the unenviable task of listening to people scream all day, but he has made some surprising discoveries about which types of scream people are best able to identify.

In 2016, an accelerator physics centre called Fermilab acquired a massive circular 50 foot magnet from a lab in New York. Too big for the roads, the magnet had to take a 2000km detour via New Orleans to get to its new home. This was the start of the “muon g-2” experiment. Last week, Fermilab announced some of their results, and they don’t quite add up. UK experiment lead Professor Mark Lancaster from Manchester University tells us what they have discovered about the tiny particle that is disobeying the laws that govern how our entire universe fits together.Mountain gorillas are among the most impressive and powerful primates alive today. Living in the dense forests of eastern and central Africa, they are able to communicate with other gorillas a mile away by cupping their hands and beating their chests. Primatologist Edward Wright and colleagues have been studying male silverback gorillas and explains how gorillas use chest beating to attract potential mates and suss out competitors. And Professor Corey Bradshaw from Adelaide, South Australia sheds light on a more fearsome animal: sharks. His research has investigated the likelihood of shark attacks around the Australian coast into the future, up to 2066, and asked what would happen to those figures if everyone wore an electrical emitter that interferes with the sharks electrical senses. He finds that shark attacks are remarkably low already, but these emitters could reduce bites by up to 3000 over the next 50 years. Super fans around the world have learned to speak fluent Klingon, a fictional language originating from Star Trek. In a quest to understand the science behind these languages often dismissed as gobbledygook, Gaia Vince has been speaking to some of the linguists responsible for creating these languages. It’s time for her to relax the tongue, loosen those jaw muscles and wrap her head around the scientific building blocks embedded in language and what languages like Klingon tell us about prehistoric forms of communication.Presented by Marnie Chesterton Produced by Rory Galloway
