About two-thirds of the world's grasslands have turned into desert. Allan Savory has devoted his life to stopping it. He now believes that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.
Psychologist Barry Schwartz takes aim at a central tenet of western societies: freedom of choice. In Schwartz's estimation, choice has made us not freer but more paralyzed, not happier but more dissatisfied.
Trout fishing is a magnet that draws people from around the world to places like Ovando, Mont. Just ask the owner of Blackfoot Angler and Supplies, Kathy Schoendoerfer.
"Every state in the nation has been through this little shop in Ovando, Montana, population 50," says Schoendoerfer with a mix of pride and perhaps a little fatigue. "And we've also had everybody from Russia, Latvia. We get a lot of Canadians, France, Finland, Brazil, Scotland, Germany, South Africa. We get a lot of business out here. You know, fly-fishing is huge."

Scientists have used some new tricks and old dogs to show that thousands of years ago, wolves may have first become man's best friend in Europe.
Researchers extracted DNA from ancient wolf or dog fossils and compared it with DNA from modern dog breeds and wolves. Until recently, labs didn't have the kind of genetic tools they'd need to work with such old dog DNA and do this kind of detailed comparison.
