Racial disparities exist, but what causes them can be complicated. Harvard anthropology student Jason Silverstein says it has to do with a lack of empathy. Host Michel Michel Martin talks with Silverstein about a Slate article he wrote titled, 'I Don't Feel Your Pain.'

To keep America's wilderness anything like it used to be when the country was truly wild takes the help of biologists. They have to balance the needs of wildlife with those of cattle-ranching and tourism, and even weigh the value of one species against another. Ultimately, they have to pick and choose who makes it onto the ark. And, as scientists in Montana's Centennial Valley have discovered, all that choosing can be tricky.
America is as much of a melting pot for dogs as it is for their human friends. Walk through any dog park and you'll find a range of breeds from Europe, Asia, even Australia and mutts and mixes of every kind.
But a few indigenous breeds in North America have a purer pedigree — at least one has genetic roots in the continent that stretch back 1,000 years or more, according to a new study. These modern North American breeds — including that current urban darling, the Chihuahua — descended from the continent's original canine inhabitants and have not mixed much with European breeds.

Unlike the dodo that sits next to it on an NPR Science Desk shelf, this year-and-a-half-old Twinkie is still around — but that doesn't mean you want to eat it.

We have to confess: When we heard that Twinkies will have nearly double the shelf life, 45 days, when they return to stores next week, our first reaction was — days? Not years?
Urban legend has long deemed Twinkies the cockroaches of the snack food world, a treat that can survive for decades, what humanity would have left to eat come the apocalypse. The true shelf life — which used to be 26 days — seems somewhat less impressive by comparison.

We open our hymnals to Hymn 379, and we begin to sing. "God is Love, let heav'n adore him / God is Love, let earth rejoice ..."
Lifting voices together in praise can be a transcendent experience, unifying a congregation in a way that is somehow both fervent and soothing. But is there actually a physical basis for those feelings?

Scientists in the National Oceanic and Atmospheric Administration are still trying to understand what exactly caused a tsunami to strike the East Coast in June. There was no seismic record of the incident. But a team of scientists came together to analyze tidal and weather data. They believe the tsunami may have been caused by a weather phenomenon known as a "derecho."
