Dr Krystal joins Dr Shane in the studio. In news, cure for River Blindness approved by FDA and a discussion on whale sharks

First guest is Dr Sarah Dunstan from the Peter Doherty Institute for Infection and Immunity. A study into the population and spread of tuberculosis-causing (TB) bacteria in Ho Chi Minh City, Vietnam, has found that more than half of cases can be attributed to one particular strain of the bacteria. A Melbourne-led international collaboration, sequenced the DNA from bacteria in TB patients Ho Chi Minh City. The findings concluded that the strain of TB-causing bacteria known as the Beijing lineage, was responsible for 59 per cent of infections. Second (and third) guests are Dr Mark Hulett and Dr Marc Kvansakul, from La Trobe Institute for Molecular Science. A team of scientists from Melbourne's La Trobe University has shown a protein found in a tobacco plant has the potential to fight life-threatening infectious diseases. The discovery could lead to the development of a new class of antibiotics and meet the challenge of rising antibiotic resistance. Third guest is Elaine Miles, Climate Data Analyst at the Bureau of Meteorology Melbourne Art conservationist and physicist with a PhD in Optics and Art Conservation, has monitored western style canvas paintings that were housed in the South East Asia region.
