Episode 274
World leaders are in Colombia for the COP16 biodiversity summit. As delegates hash out a path forward, have we actually made any progress to protect global biodiversity since they last gathered?
What would a Trump presidency mean for the climate? With the US election taking place on 5th November, two climate experts weigh in with their concerns. Leah Stokes works on climate policy at the University of California, Santa Barbara and Naomi Oreskes is a professor of earth and planetary science at Harvard.
And in a special mega feature on the microbiome, take a deep dive into the science of our guts:
First up, we know that antibiotics wipe out good and bad bacteria alike, but until now we didn’t realise just how intense those effects were. Now researchers have uncovered how many species of bacteria in our guts are killed off by antibiotics - and the truth of how long those impacts last.
We also learn how our guts are battlegrounds, where microbes are in a constant state of war, fighting for resources and territory. Most surprising of all is how some microbes are turned traitors and end up killing off their own kind.
And we provide a one-stop shop for all the science-backed ways to care for your gut and learn how the balance of microbes impacts healthy ageing, mental health and inflammation.
Hosts Rowan Hooper and Penny Sarchet (yes, she’s back!) discuss with guests James Dinneen, Michael Le Page, Carissa Wong and Alison George.
