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."
