Science: What bees and gold nanoparticles can do to cancer

Science commentator Allan Blackman joins Kathryn for a look at a new study that's found honeybees can detect the subtle scents of lung cancer in the lab - even from a patient's breath. And researchers have been looking at the benefits of gold nano-particles in fighting cancer cells - how what's been found could fuel further research and a flexible solution for separating gases could make the process less energy-intensive and cheaper. Allan Blackman is a Professor of Chemistry, School of Science, Auckland University of Technology
