Recreating the power of the sun, the dream of nuclear fusion - it’s a dream we’re inching ever closer to. A new breakthrough at a lab in the US has the team excited, and they catch up with Jeremy Chittenden, co-director of the Centre for Inertial Fusion Studies at Imperial College London, to get the latest. The team then see how evolution has proved, once again, that it is cleverer than we are, as an artificial ‘minimal cell’ created by scientists demonstrates its ability to adapt and evolve dramatically and rapidly. With the new school year not far away, fears are mounting over the covid-19 Delta variant, which threatens to sweep through our children - the team explains why the issue of ventilation must be a top priority. Things take a bizarre turn when the team finds out about a lab-grown mini human brain that has grown a pair of eyes. Also, following the IPCC report last week, and as COP26 approaches, the team checks in on the latest climate news. On the pod are Rowan Hooper, Penny Sarchet, Abby Beall and Mike Marshall.
