While much of the world is still on lockdown and with global cases of coronavirus now over two million, one positive thing that’s come out of this crisis is that we’re paying more attention to our physical fitness. In the pod this week are New Scientist journalists Rowan Hooper, Penny Sarchet and Cat de Lange. They discuss the latest UK and US government advice on fitness that emphasises how muscle strengthening is just as important as aerobic activity, and how you can do this kind of exercise even in a confined space. The team also hear what could be the first climate change song (from 1927!), explore how bats are capable of mimicking sound, discuss an on-going cosmic explosion which is the biggest ever seen, and investigate newly-invented vibrating clothing which claims to instil calmness and confidence.
