Join Jesse and Sophie as they cast their net overboard to snag last fortnight's science news before heaving it aboard with their gelatinous biceps for us all to sort through. Here's the catch: they talk about how it is that we're able to remember (tens of) thousands of faces with relative ease, a new CSIRO algorithm that can model blood vessel growth to pre-empt tumours, the ancient origins of Homo sapiens (100 000 years older than expected), and, they speak with Robert Whyte, co-author of A Field Guide to  Spiders of Australia - the latest and most comprehensive guide to those wonderful eight-legged friends.
