Did you know that the human overbite may have evolved after people began using forks and knives? In Consider the Fork, author Bee Wilson traces how kitchen tools--from knives to pots to gas stoves--have changed over time, and how they have influenced what, and how, we eat.

Vowing to stop smoking, curb spending or exercise more this January 1? Nearly half of U.S. adults will make year-end resolutions to change for the better in the coming year. Clinical psychologist John Norcross talks about how to increase the odds of success.

In time for New Year's Eve, Science Friday examines the chemical reactions that transpire in fluted glassware. Ira Flatow and Richard Zare, a chemist at Stanford University, pore over the science of bubbles — from how to keep that open champagne fizzy (forget the cork) to why beer tastes better from a glass rather than a bottle.

Move over, CSI and NCIS, there's a new game in town. Authors Eric and Natalie Yoder share some of their 'One Minute Mysteries' that can be solved with logic and knowledge of science — and without the aid of a magically fast DNA lab or improbable photo enhancement software.

What's the secret to making a fluffy omelet or the perfect pie dough? Jack Bishop, chef and editorial director at America's Test Kitchen, stops by to debunk cooking myths and highlight some of the surprising finds from the show's new cookbook, The Science of Good Cooking.

Got milk? Ancient European farmers who made cheese thousands of years ago certainly had it. But at that time, they lacked a genetic mutation that would have allowed them to digest raw milk's dominant sugar, lactose, after childhood.

Today, however, 35 percent of the global population — mostly people with European ancestry — can digest lactose in adulthood without a hitch.

Once upon a time, there was one screen that TV broadcasters needed to fill. These days, it's all about the two-screen experience.

People have been watching television with their laptops, smartphones and tablets in hand for a while now. But this year, big business tried harder than ever to bring television to a second screen.

For the Druids, mistletoe was sacred. For us, it's a cute ornament and maybe an excuse to steal a kiss. And of course it's a Christmas tradition.

But for a forest, mistletoe might be much more important. It's a parasite, shows up on tree branches and looks like an out-of-place evergreen bush hanging in the air.

Who hasn't turned a camera around at arm's length to snap a picture to send to friends or family? It always seems like it takes a few tries to frame the shot just right to capture both you and that awesome mountain summit behind you.
