Scientists are reporting that aliens are wiping out the animals in Florida's Everglades.

The aliens are Burmese pythons from Asia. They've been slithering around south Florida for decades. But scientists now say the constrictors are so bad, they're eating their way through the swamps. And the federal government has decided to take action to prevent their spread.

While the United States has mostly escaped winter, the opposite has been true in Eastern Europe. The AP reports that an intense freeze has killed at least 36 people throughout eastern Europe. In some places, temperatures dropped to negative 4 degrees Fahrenheit.

The AP adds:

In my family, we referred to them as "the brisket brigade" — those single ladies of a certain age who began bombarding my brother-in-law with casseroles and commiseration soon after my sister-in-law died. It's a cruel fact of life that nobody plies widows with months of home-cooked meals and baked goods; as Jonathan Swift might have modestly proposed, widows might as well eat each other — there's a surplus supply of them, anyway. But, a new widower gets the Crock-Pots and the romantic fantasies all fired up.

Many of the files stored by the millions of users of the cloud service Megaupload could begin losing their files on Thursday. The AP reports that federal prosecutors said Megaupload paid third parties to store data and now that authorities have freezed Megaupload's accounts, it can no longer pay those providers. The providers said they would begin deleting files as early as Thursday.

Stew's new album Making It is, in part, about his relationship with his ex-girlfriend and songwriting partner, Heidi Rodewald.

The two musicians, who still work together professionally, dated each other for years. They collaborated on songs for their band The Negro Problem, as well as on orchestrations for Passing Strange, their semi-autobiographical Broadway musical about a young African-American trying to understand himself while traveling around Europe. But during Passing Strange's initial run in Berkeley, Calif., Stew and Rodewald broke up.

Police say the combination of smoke from a brush fire and fog created a deadly environment with near-zero visibility early Saturday morning that caused a huge pileup that left at least 10 dead and 21 hospitalized on Florida's Interstate 75 near Gainesville.

In December, personal income climbed 0.5 percent, while disposable income rose 0.4 percent. New figures released today from the Commerce Department also show that consumer spending was flat, increasing 0.1 percent from the month before.

While the AP reports that rise in income was the most in nine months, the news is a mixed bag.

Gov. Andrew Cuomo wants New York City to stop requiring fingerprinting of its food stamp recipients, a stance that puts him at odds with the city's mayor, who favors the practice.

Cuomo says fingerprinting stigmatizes needy people and stops them from applying for help. In a recent State of the State speech, Cuomo pledged to stop fingerprinting food stamp recipients this year.

But New York City Michael Bloomberg says without fingerprinting, fraud would escalate.
