#28: Origin of life on Earth; second wave of coronavirus; science of miscarriage

How did life spring up on planet Earth? What happened to turn sterile, lifeless rock into cells that could harness energy, grow and reproduce?

In the pod this week are New Scientist journalists Rowan Hooper, Valerie Jamieson, Adam Vaughan and Alice Klein. They discuss the origin of life itself, and how we need a rethink of the processes that form life. Scientists are attempting to make a proto-living cell self-assemble and operate without the biochemical machinery it would usually need. 

The team also discusses the threat of a second wave of coronavirus, how we’ve reached the upper limit in terms of reopening society, and explain why transmission rates in schools should be manageable. Also, Val and Alice share honest and moving accounts of their experiences with miscarriage, as they explain the science behind why it happens, providing a new level of understanding and comfort to the 60% of women who go though pregnancy loss. In the mix too is an analysis of the shocking extent of the ongoing Arctic heatwave, and news with implications for the possibility of past life on Mars.
