Science: Wavy wounds heal faster, loathing legalese, foamy beer

Science correspondent Allan Blackman joins Kathryn to talk about a discovery by researchers in Singapore that wavy wounds heal faster than straight wounds. What implications might that have for surgery? A new study has found even lawyers hate legalese, and a frothy beer is actually better for you - don't tip that glass to avoid beer head! Allan Blackman is a Professor of Chemistry, School of Science, Auckland University of Technology.
