Dr Cat has a ribbiting conversation with Clarisse Sawyer about a pandemic that is decimating the amphibian world: chytrid fungus. Synthetic biology could be the solution – and she is researching ways to use alpacas to al-pack-a punch in the fight against this fungal infection. They also discuss how gene drives (a way of spreading manipulated versions of genes through an animal population) can tackle public health and other conservation challenges…and who should have a say in the use and control of this technology.
