Earlier this week, some of the world's leading astrophysicists came together at The Royal Society to question the very nature of our Universe. Does the Lambda Cold Dark Matter model, which explains the evolution of the cosmos and the Big Bang, need a rethink? Dr Chris North, an astrophysicist from the University of Cardiff, joins us in the studio to explain what this model says, and why it might need to be changed.
The last few weeks seem to have been a non-stop cycle of depressing climate stories, with floods in Pakistan, mass coral bleaching and last month being the hottest March ever recorded. It's perhaps no surprise that many people are anxious about the news. Vic Gill is joined by Prof Lorraine Whitmarsh, an environmental psychologist at the University of Bath, and Tom Rivett Carnac, an author, political strategist and co-host of the podcast Outrage + Optimism. Together they discuss climate anxiety, and how to stay engaged with the news without feeling overwhelmed.
And with all this wet weather, how are our precious insects faring? It turns out, bumblebees might have a trick up their fuzzy sleeves when the ground gets flooded - at least according to a new experiment led by Sabrina Rondeau from the University of Ottawa. We also get bumblebee expert Dave Goulson on the line to tell us more about these charismatic insects.
