Virologist and infectious diseases expert Prof John Fazakerley details the myriad threats to the global food supply from pathogen infestations in crops and livestock, and how new genetic and surveillance technologies are lending hope to keeping them in check. Presented by Dr Andi Horvath.
In our annual PhD episode, two young science researchers discuss their investigations of microbes that threaten, respectively, human health and our food supply. We chat with Claire Gorrie about aspects of the drug-resistant bacterium Klebsiella pneumoniae, and how it's implicated in serious infections. And Rebecca Vandegeer tells us how the Barley Yellow Dwarf virus strips our wheat crops of their defences, posing a threat to food security. Presented by Dr Andi Horvath.

Fisheries scientists Dr Tim Dempster and Dr Reg Watson discuss the pressures on wild fish stocks and debate the role of aquaculture in feeding an increasingly populous world. With science host Dr Dyani Lewis.
Science historian Professor Naomi Oreskes explains why limits in the predictive capacity of climate models present a challenge to those favoring adaptation above emissions mitigation as a strategy in dealing with climate change. With host Eric van Bemmel.
