Power plants that burn fossil fuels release carbon dioxide as well as a complex soup of chemicals, including nitrogen and sulfur. These chemicals in the air actually help keep global warming in check by reflecting sunlight back into space and by interacting with carbon dioxide. Above, the Bruce Mansfield Power Plant in Shippingport, Pa.
Cleaning up the air, while good for our lungs, could make global warming worse. That conclusion is underscored by a new study, which looks at the pollutants that go up smokestacks along with carbon dioxide.
These pollutants are called aerosols and they include soot as well as compounds of nitrogen and sulfur and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air.

Italian Premier Silvio Belrlusconi holds a pen on a note he wrote during Democratic party leader Pierluigi Bersani's speech on Tuesday.
On Tuesday, Italy's Parliament cast a vote on a measure to approve the 2010 state finances. But it was no ordinary vote: It laid bare the fact that Italian Prime Minister Silvio Berlusconi had lost a majority. That vote would eventually lead to Berlusconi offering his resignation on Wednesday.
In all the news, we missed this interesting picture:

Wilson Ramos of the Washington Nationals appears to be the first Major League Baseball player to have fallen victim to what's become an alarming trend in Venezuela: the kidnapping and holding for ransom of the rich. He was grabbed Wednesday by gunmen and hasn't been seen since.
But he's not the first major leaguer to have been touched by the epidemic of kidnappings-for-ransom in Venezuela.
'Tis almost the season, and what would the holidays be without our favorite foods?
There are the traditional standbys — like turkey and cranberry sauce at Thanksgiving, or latkes for Hanukkah. But many people also have a specialdish they eat only during the holidays. For example, one NPR reader raves about lefse, which she says is a potato-based staple for any traditional Norwegian-American holiday dinner. It's "best served hot with butter. Or cold with butter and sugar. Butter is key," she writes.
Perhaps Wild Flag's burgeoning success is due to the fact that each member is a valued veteran of the indie rock scene, with collective stints in The Minders, Sleater-Kinney, Stephen Malkmus and the Jicks, The Spells and Helium.
