"Beautiful Vivisection", painted in 2009 by artist Vincent Castiglia, is seen prior to the opening of his gallery show "Resurrection", at Sacred Gallery in New York October 3, 2012. Many artists claim to put their blood, sweat and tears into their work, but Castiglia means it: he paints with his own blood. "Resurrection" features a number of Castiglia's paintings from the last 10 years. His process includes making a preliminary pen or graphite sketch and extracting just enough "paint" in the privacy of his studio. Picture taken October 3.

Yale University physician, professor and researcher Hugh Taylor holds a mouse inside a laboratory at Yale University in New Haven, Connecticut, May 21, 2010. His research has shown that the chemical BPA (Bisphenol A) alters the way genes react to estrogen, and could open the door for infants in utero to develop cancer much later in life. To study the way BPA may affect children in utero, Taylor injected pregnant mice with high doses of the chemical five days into their 21-day gestation cycle. He found that the mice exposed to BPA in the womb lacked the "gate" on their DNA receptors and were more susceptible to estrogen for the rest of their lives.
