land and building stuff over their habitats. We're poaching and over hunting. Global warming

is shifting temperatures and migration patterns. I could go on and on. But instead, let's talk about

how we humans are using science to help bring some species back from the brink of extinction.

For Scientific American Science quickly, this is Rachel Feldman. To finish up our four-part

series about conservation science, which we're calling the new conservationists, we're talking about

our favorite kinds of animal stories, the comebacks. Our guide for this adventure is Ashley Pap,

an animal scientist turned storyteller.

And for this episode, she'll take us to Washington,

D.C., where just this past fall,

two fuzzy new VIPs arrived from China.

They're black and white and adorable all over.
