#180 Maximum human lifespan; a twist on a classic physics experiment; saving the kākāpō

How long can a human live for? The world record is 122 years, and while some people believe our bodies aren’t capable of surpassing that, a new theory suggests we could see the record broken in a decade’s time. The team explains how this could be possible. An upgraded version of the classic double-slit experiment has observed how light interacts through differences in time rather than space. Researchers used a special type of material in the experiment, which the team says could be used to make time crystals. Nutritional deficiencies, tuberculosis and self harm - child asylum seekers in Australian detention centres have experienced dire living conditions. The team finds out about the impact of these centres on their health and lessons that other countries could learn. The incredible kākāpō is our life form of the week. The team explains how researchers are trying to save this endangered, flightless bird by looking at the preserved poo of their ancestors. And it’s been discovered that giving your brain a good work-out can ramp up its waste disposal system - something we thought only happened when we sleep. The team explains how this finding may be useful for preventing neurological conditions like Alzheimer’s. On the pod are Penny Sarchet, Sam Wong, Leah Crane, Alice Klein and Clare Wilson.
