A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.
Indeed, a Gallup poll this year reported that 46 percent of Americans (58 percent of Republicans, 41 percent of Democrats and 39 percent of independents) held a nonscientific belief in creationism, the religious-based view that humans were divinely created within the past 10,000 years.

We've been hearing a lot recently about how algorithms can predict just about anything. They find long-lost friends on Facebook and guess which books we'll buy next on Amazon. Algorithms hit the big time this month, when New York Times blogger Nate Silver used mathematical models and statistics to correctly forecast the outcome of every state in the presidential election.
At Analy High School in Sebastopol, Calif., three students are taking apart a bicycle that generates electricity. Another student is calibrating a laser cutter. They're all working in a cavernous building that once held the school's metal and electronics shop. Let's just say it has been updated.
"I'm thinking that I might make a quadrocopter and a tremolo. It's a type of guitar thing that uses light to change the volume. And a few other things; we'll see," says Gabe Cook-Spillane, a senior at Analy High.
Many teens aspire to have lean bodies and big muscles, like the professional athletes they so admire. But they don't always want (or know how) to sweat to get them. A new study finds a surprisingly high number of teens have used steroids to try to slim down and bulk up.
Six percent of teenagers say they've used steroid drugs in the past year, which is a lot higher than the 1.1 percent reported in a 2011 survey.

This round of Israeli-Palestinian fighting may seem almost identical to all the battles that came before. After all, the Israelis and Palestinians waged an intense fight over the Gaza Strip just four years ago, in December 2008 and January 2009.
But since then, the Arab Spring and its aftermath have radically altered the dynamics of the Middle East. Here are several reasons to look at this clash from a different perspective:

Just days before the movie's premiere, there's word that during the filming of director Peter Jackson's The Hobbit: An Unexpected Journey as many as 27 animals used in its production died at the farm in New Zealand where they were housed.
Animal wranglers tell The Associated Press that there were "bluffs, sinkholes and other 'death traps' " at the farm. Three horses died, along with "six goats, six sheep and a dozen chickens."

There are people (and I hear from them constantly) who think if a subject is sophisticated, like science, the language that describes it should be sophisticated, too.
If smart people say torque, ribosome, limbic, stochastic and kinase, then the rest of us should knuckle down, concentrate and figure out what those words mean. That's how we'll know when we've learned something: when we've mastered the technical words.
