21 h. ago The tech behind genetically modified babies is getting a reboot

A Chinese scientist, He Jiankui, made a shocking announcement to the world in 2018: He had secretly engineered the birth of the first gene-edited babies. The birth of the twins was seen as reckless and unethical by the scientific community. That’s because, among other things, the CRISPR gene-editing technique Jiankui used was so new. NPR science correspondent Rob Stein has been following the controversial world of gene-editing and human reproduction, including some companies’ recent quests to push gene-editing technology forward.Read more of Rob Stein’s reporting on the topic here.Interested in more science news?

45 h. ago Did life start on the ocean floor — and what does that mean for alien life?

How did life start on Earth? The answer is a big scientific mystery scientists are actively investigating. After talking with many scientists, host Regina G. Barber found that an abundance of water on Earth is most likely key, in some way, to the origin of life — specifically, in either deep sea hydrothermal vents or in tide pools. It's for this reason some scientists are also exploring the potential for life in so-called "water worlds" elsewhere in the solar system, like some of the moons of Jupiter and Saturn. This episode, Regina digs into two water-related hypotheses for the origin on life on Earth — and what that might mean for possible alien life.Have another scientific mystery you want us to cover on a future episode?

7 d. ago 'Zombie' cells have scientists rethinking how we age — and what to do about it

It’s no secret that stress isn’t good for you. But just how bad is it? Well, in the last few decades, scientists have linked psychological stress to changes in our DNA that look a lot like what happens on the molecular level as we age. Today on the show, host Regina G. Barber talks to freelance science journalist Diana Kwon about the latest research on stress and aging, including a new hypothesis for how your brain handles aging — and what science could do about all of it.Interested in more aging science?
