Science commentator Dr Jen Martin joins Kathryn to discuss three studies.
The first looks at what researchers found by studying the microbiome of the world's oldest known person - including that her gut was as diverse as someone much younger - so what was she eating?
Does playing a musical instrument help children learn to read? And why do cats eat grass?

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.
