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."

Turn 50, and you can pretty much count on an invitation to join the AARP and a referral to the gastroenterologist to be screened for colon cancer.
Two-thirds or less of people ages 50-75, the target range for colorectal cancer screening, are up-to-date on testing, according to the Centers of Disease Control and Prevention.
That's better than it used to be, but still isn't up to par. The national screening goal is 70.5 percent of eligible people in 2020.
