#109: Ukraine war stokes energy crisis; emergency sounded over Amazon rainforest; secular intelligent design; mammalian virgin birth
from The World, the Universe and Us · host New Scientist
The war in Ukraine has sparked an energy crisis, as European countries attempt to cut ties with Russia. The team discusses what this means for the future of energy production and how it may speed up our pivot to renewable energy. They also explore the growing concerns at various nuclear sites in Ukraine, as some have been seized by the Russians, while others have been damaged during the conflict. For the first time a virgin birth has taken place in a mammal - a female mouse has given birth without any input from a male. The team explains how CRISPR gene editing has been used to create embryos from unfertilised eggs. As the Amazon rainforest becomes less resilient to drought, there are fears it may be passing a tipping point that could turn the whole system from forest into savannah. Earth system scientist Tim Lenton of the University of Exeter explains the devastating global impact this would have. Taking a much-needed trip off the planet, the team discusses two stories from Mars, one from NASA’s Perseverance rover and another from China’s Zhurong rover. We also present an audio space-quiz you can take part in! Thanks to NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaéro for the audio clips. And legendary cosmologist Martin Rees shares his thoughts on the existence of extraterrestrial intelligence in the universe and the fascinating concept of ‘secular’ intelligent design. On the pod are Rowan Hooper, Penny Sarchet, Matt Sparkes, Adam Vaughan and Richard Webb. To read about these stories and much more, subscribe at newscientist.com/podcasts.
