Coronaviruses don’t usually produce a strong “immune memory”, and that has been worrying scientists, because it spells trouble for long-term immunity and the development of a vaccine. But, thankfully, the coronavirus that causes covid-19 doesn’t seem to be typical.In the pod this week are New Scientist journalists Rowan Hooper, Penny Sarchet and Graham Lawton. They explore new research that suggests people are developing immunity to the disease.The team also discusses how CRISPR gene editing has been used to treat two inherited genetic diseases in humans for the first time, they reveal the startling news that some snakes can fly (sort of), and from Donald Trump to Jacinda Ardern, they hear about possible evolutionary reasons behind the two types of leader in today’s world. All that, and positive news about some nearby exoplanets.
