Some scientists looking to preserve vulnerable species have turned to a controversial technique: synthetic biology. This catchall term often means genetic engineering – introducing new genes to an organism. And a recent narrow vote by the International Union for Conservation of Nature on using the technology shows how divided scientists are on the issue of releasing genetically altered species. Science correspondent Nate Rott wades into the debate with us and reveals whether or not the Union voted to place a moratorium on releasing gene-edited species.Read more of Nate’s reporting on the topic.

I'm Rachel Martin. If you're tired of small talk, check out the Wild Card podcast. I invite influential thinkers to open up about the big topics we all think about but rarely talk about. Tune in this fall to hear Mel Robbins, Malala Yousafzai, and Brene Brown talk about everything from grief and God to ambition and forgiveness.
Watch or listen on the NPR app, YouTube, or wherever you get your podcasts. You're listening to Shortwave from NPR. Hey, short wavers, Emily Kwong here. Today, we're going to focus on an emerging field that could help the natural world, but is also a little controversial.
Yes, controversial because it gets at an almost like philosophical question, Emily, about what our role should be in the natural world.
Science correspondent Nate Rott, ever the philosopher.
And I'm a pretty poor excuse for a philosopher. But, you know, I think the easiest way to explain this technology that we're going to be talking about is to start with an effort that's going on to save something we all know and love. Frogs.
Frogs are little wet things that run around in the mud. They should be absolutely just covered in infections at all times. And the reason they're not is they produce antibiotics.
This is Anthony Waddell, a researcher at Macquarie University in Australia. It's just chytrid is too good. Chytrid fungus, which is like this horrendous and deadly skin disease affecting amphibians that, you know, the antibiotics they have often can't fix. And this disease is now found on every continent except Antarctica.
It's considered the worst pandemic ever, worst invasive species ever in terms of biodiversity loss.
Anthony has been focused on protecting frog populations from chytrid pretty much his entire scientific career. And he started with the type of desert frog that lived near his hometown, Las Vegas.
