	Description:		This week the UK Health secretary raised concerns over a new variant of SARS- CoV-2 currently spreading across Europe. Viruses mutate all the time so it’s no surprise that a new form of the one causing Covid -19 would emerge. However, virologist Ravi Gupta who analysed the new strain says we need to be weary in case future strains mutate in ways that could overcome vaccines. Immunologist Akiko Iwasaki is part of a team looking at the impact of Covid -19 on our immune system. Her research has uncovered autoantibodies linked to infection with the virus. These are responsible for a number of autoimmune diseases. The finding goes some way to explaining the symptoms seen by some people long after a Covid -19 infection. And how clever are ravens? According to behavioural scientist Simone Pika at the Max Planck Institute for Ornithology in many ways they are up there with chimps or young children. She found they performed well in tests designed for primates. Following the dinosaur destroying meteor strike where was the best place for life to develop a new? Geologists, David Kring and Tim Bralower, think they’ve found the answer hidden in plain sight. (Image: Getty Images) Presenter: Roland Pease Producer: Julian Siddle
