Spring has sprung and… ACHOO!! Yep, hay fever is back with a vengeance. This week the team has some bad news for hay fever sufferers, as allergies are set to get worse (in every way imaginable) because of climate change. The team then ramps up the excitement with the news that there may be an ancient black hole sitting on the edge of our solar system, which might actually be within our reach! They discuss vanilla’s attempts to break free of its ‘boring’ stereotype, as growers begin to experiment with new and exciting flavours of the classic taste. As countries around the world prepare for a third wave of covid-19 infections, the team explains how the vaccine rollout will impact hospitalisation and death rates. And they also celebrate the Octopus, as new research suggests they might be able to dream. On the pod are Tiffany O’Callaghan, Graham Lawton, Stuart Clark and Clare Wilson.
