Science correspondent Dr Jen Martin joins Kathryn to talk about three new studies.
One looked at what happens in the brain when someone blushes - the study used an innovative means of getting participants to blush that involved Mariah Carey!
Another study looked at whether our memory for music diminishes with age and a new test for sepsis could help save patients from dying with the condition and curb the use of antibiotic over-use.
Dr Jen Martin founded the science communication program at the University of Melbourne, runs the espressoscience.com blog and is also the author of 'Why Am I Like This?: The Science Behind Your Weirdest Thoughts and Habits'.
