Over five million people in the U.S. claim some form of Native American identity, according to the U.S. Census Bureau. As part of Tell Me More's series on Native American Heritage Month, host Michel Martin speaks with author Anton Treuer about America's first people and how they're reflected in pop culture.
Scientists may have finally solved a problem that has plagued beer drinkers for ages: Insufficient foam resiliency.
As any beer drinker can tell you, a tall glass of lager without a white, foamy head on top just doesn't look right. And even if you start out with one, it can dissipate fast. And that's just sad.
Now, microbiologists have identified the specific gene in yeast responsible for a beer's head and they say this discovery can lead to stronger, longer lasting, more aesthetically pleasing foam on your favorite brews.

"PIGS" are a hot topic in Germany's capital.
Attend any press briefing about how German Chancellor Angela Merkel is going to solve the European debt crisis, and you're likely to hear that acronym, which stands for "Portugal, Ireland (or Italy), Greece and Spain."
But recently, pigs of an altogether different variety made headlines in Berlin.
Brian Shaffer tests an exoskeleton developed by researchers at Vanderbilt University at a rehabilitation center in Franklin, Tenn. The exoskeleton locks around the legs and feet. To stand up, a paralyzed person simply leans forward.
