It's not the first study that finds the lowly aspirin may protect against the deadliest kind of skin cancer, but it is one of the largest.

And it adds to a mounting pile of studies suggesting that cheap, common aspirin lowers the risk of many cancers — of the colon, breast, esophagus, stomach, prostate, bladder and ovary.

If you've had wrist and shoulder pain from clicking a mouse, relief may be in sight. This spring, a new motion sensing device will go on sale that will make it possible for the average computer user to browse the Web and open documents with a wave of a finger.

The Leap Motion Controller is on display at the South by Southwest Interactive conference in Austin, Texas, for the first time. It's one of the most talked about startups at the conference, where some 26,000 people have gathered to see emerging tech companies.

Of all the posters plastered around Facebook's Silicon Valley headquarters — "Move Fast and Break Things," "Done Is Better Than Perfect" and "Fail Harder" — Chief Operating Officer Sheryl Sandberg has a favorite: "What Would You Do If You Weren't Afraid?"

Greg, Tom, and Liz talk with Jenny Brown, co-founder & director of the Woodstock Farm Animal Sanctuary.  Brown explains how a childhood bout with cancer and the companionship of a cat awakened her awareness to the inner lives of animals.  As an adult, Brown did undercover investigations of factory farms to try to expose the abuses at these facilities.  Brown also talks about trying to convince people that there really is no difference between our beloved companion animals and the animals at factory farms who eventually end up on our grocery shelves as bacon or ground beef.  www.woodstocksanctuary.org

The American conservative movement has its homecoming this week: the Conservative Political Action Conference, where everyone from politicians to peddlers is out to inspire the faithful.

Last year, one of the headline speakers was former vice presidential candidate Sarah Palin, who harked back to the second-ever CPAC in 1975, when Ronald Reagan laid out a vision for a conservative Republican Party.

She invoked his image of a banner of bold colors, not pale pastels.
