2021 could well go down in history as the year we saved our planet… the alternative really doesn’t bear thinking about. Luckily the team brings news of a “rescue plan for nature”, with several initiatives launching this year including the UN Decade of Ecological Restoration. NASA’s Mars lander Perseverance has successfully touched down on the Red Planet. The team discusses its goals, and shares the latest on the two craft which entered Mars’ orbit last week, China’s Tianwen-1 and the UAE’s Hope. The team highlights a newly discovered covid-19 mutation which is a combination of the variants first found in Kent and California. And they answer the questions “why is ice slippery?”, “why do flames jump up and down?”, and “why aren’t people at the South Pole upside down?”. On the pod are Graham Lawton, Anna Demming, Caroline Williams, and Richard Webb. To read more about the stories, subscribe at newscientist.com/podcasts.
