In science news around the world, a new biomedical "golden triangle" dubbed MedCity launches in London, NASA suspends scientific collaborations with Russia, pro-life groups in Europe launch a new attack against E.U. funding for stem cell research, and more.
Science talks with Saudi prince and science enthusiast Sultan Bin Salman Bin Abdul-aziz Al-Saud about archaeology and Arabia's prehistoric past. And a bird flu scientist-turned-member of the Italian Parliament is allegedly under investigation for trafficking in flu viruses.
A new exhibit on pterosaurs at New York City's American Museum of Natural History features life-size models of the largest and smallest known species of the flying reptiles, an interactive flying pterosaur exhibit, and even a trading card game.

Scientists have come up with a gallery of rogues to explain an epidemic of kidney disease in Central America. But the culprit has stayed one step ahead.
Jon Cohen
Starting in the 1950s, researchers hunted for the cause of an unusual chronic kidney disease afflicting farming communities in the Balkans. It took a mishap with Chinese herbal medicine in Belgium and the dogged sleuthing of molecular epidemiologists to arrive at the culprit.
