Science correspondent Siouxsie Wiles joins Kathryn to talk about a new study which suggests having the sex talk with your kids won't delay them having sex - but it's more likely to be safe.
Unhatched chicks communicate with their siblings, vibrating their egg shells to warn their brothers and sisters of danger, and researchers have developed a stickier plaster inspired by the seamless and scar-free healing process seen in animal embryos.
Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
