It’s been half a year since coronavirus and covid-19 emerged and the world dramatically changed. Our understanding of the virus and the disease has also hugely changed in those six months, and it’s time to take stock on our understanding of how it spreads, its symptoms and how to tackle it.

In the pod this week are New Scientist journalists Rowan Hooper, Valerie Jamieson and Cat de Lange. They explore the various methods being used in the fight against coronavirus, why some countries have seen second waves while others haven’t, and explain why horror movie fans seem to be more mentally resilient during the pandemic.

The team also discusses yet another piece of evidence showing the world’s need to cut down on meat and dairy production, this time because of the industry’s massive contribution to global nitrogen emissions. They talk about the possibility of gravitational rainbows with the news that gravity itself may have a weight, celebrate the anniversary of the discovery of the Higgs boson, and share exciting news about two debut missions to Mars, one from United Arab Emirates, another from China.
