Senate Minority Leader Mitch McConnell, R-Ky., prepares to announce a debt ceiling deal in July 2011. That deal laid the foundation for the across-the-board spending cuts set to take effect on New Year's Day, 2013.
New Year's Day typically inspires hope and new beginnings. But this next one may be cause for trepidation. Tax cuts for all income levels expire on Jan. 1, 2013, and most federal programs will face a 10 percent haircut — because Congress failed to agree on a deficit-reduction plan.

Over the last three decades, diagnoses of early-stage breast cancers soared, largely due to routine mammogram screening. But the incidence of late-stage cancers declined only slightly. That leads some to question whether mammograms are really doing what they're supposed to — catching early cancers before they progress.
The endless debate over routine mammograms is getting another kick from an analysis that sharply questions whether the test really does what it's supposed to.
Dr. H. Gilbert Welch, coauthor of the analysis of mammography's impact, which was just published in The New England Journal of Medicine, tell Shots that the aim was to "get down to a very basic question."
Why people yawn is a mystery. But yawning starts in the womb.
Past studies have used ultrasound images to show fetuses yawning, but some scientists have argued that real yawns were getting confused with fetuses simply opening their mouths.
So Nadja Reissland, a researcher at the University of Durham in the United Kingdom, used a more detailed ultrasound technique to get images of fetal faces that could distinguish a true yawn from just an open mouth.
