But what do floods mean for mosquito-borne diseases? 00:36:10 By studying sleepless flies, scientists have identified a gene that puts them to sleep when they need it the most. And interestingly, it doubles as part of their immune system. 00:42:32 From our immune system to taste and even our emotions - our guts have a big influence on our brains. And now new research shows that gut bacteria can affect our our mental health. Dr. Cameron Webb is a medical entomologist from the University of Sydney and NSW Health Pathology primarily interested in mosquitoes, mosquito-borne disease management, insect repellents and wetland rehabilitation. This episode contains traces of Abigail Fraeman, Mars Exploration Rover (MER) deputy project scientist at JPL.
