The first images from the brand new Vera C. Rubin Observatory have finally been unveiled, and they show us the cosmos like never before. The camera captures so much detail that its first complete image contains about 10 million galaxies. Host Flora Lichtman talks with Dr. Federica Bianco about our dazzling new view of the night sky, how the camera works, and what cosmic mysteries it may reveal.See images from the telescope on our website.Guest: Dr. Federica Bianco is an astrophysicist at the University of Delaware and the deputy project scientist for the Vera C. Rubin Observatory.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

Last month, scientists reported a historic first: they gave the first personalized gene-editing treatment to a baby who was born with a rare life-threatening genetic disorder. Before the treatment, his prognosis was grim. But after three doses, the baby’s health improved. So how does it work? What are the risks? And what could this breakthrough mean for the 30 million people in the US who have a rare genetic disease with no available treatments?To help get some answers, Host Flora Lichtman is joined by the physician-scientists who led this research: geneticist Dr. Kiran Musunuru and pediatrician Dr. Rebecca Ahrens-Nicklas.Guests: Dr. Rebecca Ahrens-Nicklas is an assistant professor of pediatrics and genetics at the Children's Hospital of Philadelphia and the University of Pennsylvania.Dr. Kiran Musunuru is a professor of translational research at the University of Pennsylvania.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Australia is known for its unusual animal life, from koalas to kangaroos. But once upon a time, the Australian landscape had even weirder fauna, like Palorchestes azael, a marsupial with immense claws and a small trunk. There was Protemnodon mamkurra, a massive, slow-moving, kangaroo-like creature. And Zygomaturus trilobus, a wombat the size of a hippo. They’re all extinct now, and researchers are trying to figure out why. Host Flora Lichtman talks with researcher Carli Peters about ZooMS, a technique that allows researchers to use collagen from ancient bone fragments to identify species, offering clues to those ancient extinction events. Peters recently described using the technique in the journal Frontiers in Mammal Science.And, a recent study in the journal Nature Astronomy hints that our own Milky Way galaxy may not be doomed to collide with Andromeda after all. Till Sawala, an astrophysicist at the University of Helsinki, joins Flora to talk about the finding.Guests: Dr. Carli Peters is a postdoctoral researcher at the Interdisciplinary Center for Archaeology and the Evolution of Human Behavior at the University of Algarve in Faro, Portugal.Dr. Till Sawala is an astrophysicist at the University of Helsinki.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
