The Large Hadron Collider might, just might, have found something that challenges the Standard Model of particle physics. The team hears why an anomaly concerning a quark could hint at a crack in our understanding of physics. They also find out whether the age-defying, rejuvenating properties of human embryos can help us reset the ageing process in adults. As the Perseverance rover has been on Mars for a month now, there is of course more news from our neighbouring planet, namely new recordings from the surface to listen to, and the upcoming launch of the Ingenuity helicopter. Also on the pod is the worrying story of vaccine hesitancy in the EU, and the team celebrates a microbe unlike anything seen before. On the pod are Rowan Hooper, Tiffany O’Callaghan, Layal Liverpool, Richard Webb, Chelsea Whyte and Leah Crane. To read more about the stories, subscribe at newscientist.com/podcasts.
