Scientists tinkering around with the creation of synthetic life have taken a significant step forward. The team explains how synthetic cells could one day be implanted in humans. Alongside this is the news that researchers have used frog skin cells to create a microscopic living robot, which can heal and power itself. As levels of CO2 in the atmosphere reach a record high, the team looks at ways to join up global efforts in tackling both the climate and biodiversity emergencies. They discuss another challenge to the Standard Model of particle physics, as Fermilab’s muon g-2 experiment threatens to shake up everything we thought we knew. And finally the team explains how the asteroid that killed the dinosaurs gave rise to the Amazon rainforest, and explore news of rare blood clots linked to the AstraZeneca coronavirus vaccine. On the pod are Rowan Hooper, Tiffany O’Callaghan, Layal Liverpool, Richard Webb and Krista Charles. To read about these and much more, subscribe at newscientist.com/podcasts.
