She also had some impressive theater and film credits, among them a role in Arthur Miller’s Mr. Peter’s Connections, in which she performed (in the buff, no less) alongside actor Peter Falk. [More]

Bright Bugs Clue for Plant Medicinals [60-Second Science]
Lundi 14 Juillet 2008 - 22:01 - 4 mois, 2 semaines depuis - Cancer - Scientific American
[The following is an exact transcript of this podcast.]In the insect world, bright reds, oranges and yellows can be a warning: “Eat me at your own risk, pal.” Because colorful bugs can be toxic, they often get their chemical protection from nibbling poisonous plants. But these poisons can have a flip side for us--some fight cancer or tropical parasites that cause diseases like malaria. [More]

Is China's Pollution Poisoning Its Children? [Features]
Lundi 14 Juillet 2008 - 08:00 - 4 mois, 2 semaines depuis - Cancer - Scientific American
Editor's Note: This story will be published in the August issue of Scientific American.A few heaping piles of scrap metal and a rusty coal shed are all that is left of the power plant that until recently squatted like an immense, smoke-belching dragon in the middle of Tongliang, a gray city of 100,000 in south-central China. As we walk toward the shed, a Belgian Shepherd begins barking furiously, jerking its iron chain and baring sharp teeth. A brown-eyed face peeks out from the open doorway--it belongs to a girl in a stained shirt, holding a tabby cat that jumps away to hide under a slab of concrete as we approach. The girl is no more than six or seven years old and appears to be living in the shed with her father, who watches us warily from within. [More]

News Scan Briefs: Eating with Tension, Cancerous Marriage, Milk and Diabetes
Mercredi 09 Juillet 2008 - 05:58 - 4 mois, 3 semaines depuis - Cancer - Scientific American
Eating with TensionThe long, thin beaks of shorebirds called phalaropes are no good at sucking up water and any tasty crustaceans within. Instead they rely on the attractive force of liquid known as surface tension to ferry prey upward. The birds first swim in small, fast circles on the surface of the water, creating a vortex that pulls creatures up within their reach. They next peck at the water and then rapidly open and close their beaks. This scissoring motion both pulls and squeezes droplets, about two millimeters in size, and moves them from the tip of their beaks into their mouths. In experiments with mechanical beaks, scientists at the Massachusetts Institute of Technology and the French National Center for Scientific Research find that the droplets do not move well if the water contains oil, detergents and other pollutants that alter water’s surface tension. Draw in the findings from the May 16 Science. [More]
