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.
Superstorm Sandy sparked a lot of interest in rising sea levels when it swept across the Northeast last month and flooded parts of the coast. Over the next century, more water — and higher sea levels — could come from melting ice in Greenland and Antarctica. How much has been unclear.
But now scientists have developed a much clearer view of how quickly that ice has been melting over the past two decades. And that will help researchers forecast the rate of sea-level rise in the years to come.
Before Secretary of State Hilary Rodham Clinton passes the reins to her successor, she's got a few loose ends to tie up. One of them is mapping out the U.S.'s continuing efforts to combat AIDS around the world.

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.
Blues is so much a part of the fabric of American music and American culture — not only as a defined musical form, but also as a springboard for all kinds of creativity — that it seems crazy to try to encapsulate it in any way. Bear Family Records, though, has just released a 12-disc survey of electric blues called Plug It In! Turn It Up! that does a great job of illuminating one particular aspect of the blues.

Yes, he talked about the negotiations over taxes and spending cuts. Yes, it was a holiday photo op. But what really struck us about Vice President Joe Biden's this morning to Washington, D.C.'s first Costco store was how, once again, he just seems to have so much fun.
