Where did covid-19 really come from? Well, the team explains why the wet market in Wuhan is back on top as the most likely place of origin. They also look ahead to the future of the pandemic, as the delta variant continues to run rampant across the globe. In eyesight news, forget carrots - if you want to improve your vision all you need (maybe) is some red light. The team digs into new research which shows that red light can boost mitochondrial activity in cells - but will it prove useful? The team get a little self conscious when the topic of body odour comes up. But this story is actually about an odourless chemical that we emit, that seems to influence human behaviour - affecting men and women differently. They also touch on an innovative new climate-saving method of making plastic, and they find out why NASA is sending a rocket to smash into an asteroid. On the pod are Rowan Hooper, Penny Sarchet, Clare Wilson and Michael Le Page. To read about these stories and much more, subscribe at newscientist.com/podcasts.
