Can we produce packaging that isn't going to seriously harm the environment? The answer may lie with bioplastics but, there is a great deal of confusion about what alternatives there are. Unlike conventional plastics that are made from petroleum, bioplastics are made from plants or other biological material. But it's worth having a good look at the different types - as some have greener credentials than others.

11:45 Safe sex talks, unhatched chick bonds and stickier plaster

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.
