Since the Covid-19 pandemic began, scientists studying the virus have become targets of online harassment, and more recently, death threats. Roland speaks to Dr Angela Rasmussen, virologist at the Vaccine and Infectious Disease Organization at the University of Saskatchewan, about her experiences.

Spyros Lytras, PhD candidate at the University of Glasgow, talks Roland through the evolutionary history of the virus that causes Covid-19 and how there isn鈥檛 just one ancestor, but several.

Anti-Asian sentiment has seen a big increase since the pandemic. Dr Qian He, Postdoctoral Research Associate at Princeton University, looked into how US-China relations have influenced how Americans view Chinese today.

And we hear from scientists on board the RRS Discovery, which is currently located near St Helena and Ascension Island, surveying the health of the surrounding ocean. On board documentary filmmaker Lawrence Eagling talks to Shona Murray, pelagic ecologist from the University of Western Australia, and Gareth Flint, mechanical engineer at British Antarctic Survey, about their work and findings.

Why don鈥檛 we fall out of bed when we鈥檙e asleep? That鈥檚 the question that鈥檚 been keeping CrowdScience listener Isaac in Ghana awake, and presenter Alex Lathbridge is determined to settle down with some experts and find an answer.

Once our sleep experts are bedded in, we鈥檒l also be wondering why some people laugh in their sleep, why others snore and how some people can remember their dreams.

And Alex takes a trip to the zoo to meet some animals that have very different sleep patterns to humans. It鈥檚 his dream assignment.
