Facebook has a long history of upsetting its users by suddenly announcing a change to its privacy settings. In 2009, as a way to quiet the critics, Facebook set up a system for its customers to vote on changes. If enough of them were unhappy, the company would back down. Now, Facebook wants to get rid of the voting.
The Senate Judiciary Committee approved legislation to make old emails a little more private on Thursday. The legislation also applies to old Facebook posts, Google documents and anything else you might be hiding online behind a password.

There's a greenhouse boom around the country, thanks in part to the "buy local" movement. Paul Mock grows tomatoes, herbs and other veggies year-round in his Berkeley Springs, W.Va., greenhouse and sells to groceries and restaurants in the Mid-Atlantic.

"This is unprecedented, the level of opportunity," says Mock, whose business is booming.
It may sound like an oxymoron: a delicious local, winter tomato — especially if you happen to live in a cold climate.
But increasingly, farmers from West Virginia to Maine and through the Midwest are going indoors to produce tomatoes and other veggies in demand during the winter months. "There's a huge increase in greenhouse operations," Harry Klee of the University of Florida tells us.
Mercury is not the first planet to come to mind if you were searching for ice in the solar system. After all, the surface temperature across most of the planet is hot enough to melt lead.
But at the poles on Mercury it's a different story. Almost no sun reaches the poles, and as a result, temperatures can drop to less than -100 degrees Fahrenheit. Now, three papers in the journal Science suggest there really is ice at the bottom of craters near the poles on Mercury.
The explosion in world popularity of quinoa in the past six years has quadrupled prices at retail outlets. But for all the demand from upscale grocery stores in America to keep their bulk bins filled with the ancient grain-like seed, almost no farmers outside of the arid mountains and coastal valleys of Peru, Bolivia, Ecuador, and Chile grow it.
But plant breeders and scientists who study the biology and economics of quinoa say that is about to change.
Spinach has lots of opportunities to pick up E. coli and other bugs during harvest and growing. Here, a Mexican migrant worker cuts organic spinach during the fall harvest at Grant Family Farms in Wellington, Co.
Salad producers haven't succeeded in banishing E. coli and other dangerous microbes from fresh greens, though they've tried hard. As we've reported before, it's a major challenge to both growers and the environment. But one scientist thinks he's making progress – with a spinach spa that zaps bad bugs with ultrasound.
