Most of us do everything possible to avoid mosquitoes. But one Italian researcher literally sacrifices her right arm to keep the lowly insects alive.
Chiara Adolina is studying a new malaria drug, and she needs the little suckers for her experiments. So she feeds them each day with her own blood.
She extends her arm into a mosquito cage to give the insects "breakfast." Several dozen mosquitoes spread across her forearm and jam their proboscises into her skin. "Can you see how fat they become?" she says. "Look at that tummy."
The millions of Americans who make New Year's resolutions to lose weight often have pictures in mind.
They're pictures that have been repeatedly supplied by the health and beauty magazines at supermarket checkout lines. They feature skinny models in bikinis, or toned guys with six-pack abs, and captions about how you could look like this by summer.
Some people go so far as to tape these pictures onto their refrigerators and cupboards. When they're tempted to reach for a cookie, they reason, the sight of that toned model might dissuade them from breaking their resolutions.
The U.S. Navy version of the F-35 Joint Strike Fighter conducts a test flight on Feb. 11, 2011, over the Chesapeake Bay in Maryland. The F-35 is the fighter jet of the future for the U.S. military, but its high cost and many delays have raised questions.
After years on the drawing boards and in testing labs, a new fighter plane is entering the U.S. arsenal. The F-35 Joint Strike Fighter is supposed to help the Air Force, the Navy and the Marines replace their fleet of aging aircraft.
But this plane has become the most expensive military procurement program in history. While critics continue to carp about the cost, the plane is now in the skies, and the military says it's the lynchpin for future defense strategies.
For those dearly devoted of you who paid attention to me in September, I noted that the best bet in the NFL had proven to be whenever a West Coast team played an East Coast team at night, because the Pacific players had their body clocks better set.
