Relationships + face recognition, chimp self-medication

Science correspondent Jen Martin joins us to talk about how your ability to recognise faces might be affected by how many high-quality close relationships you have. Chimpanzees have been observed going out of their way to find plants with medicinal qualities when they're ill. And a study in rats has found that a key brain signal linked to memory formation deteriorates after broken sleep. 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.
