Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

.... “Climate change will drive animals to move to new places,?says Lauren Buckley, a postdoctoral fellow at the Santa Fe Institute who is a visiting scholar at UCSD and the other co-author of the study. “Our research suggests that those animals that move to islands can strongly affect the sensitive anim...

Novel system developed to turn data into real-time, interactive 3-D images

Master regulatory gene of epithelial stem cells identified

...sloughs off is controlled by a variety of genes. A new study from Harvard Medical School published in the May 4 issue of Cell, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenital tract. This ma...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...id these findings, if confirmed in humans, open up new avenues for the development of non-desensitizing drugs not only for heart failure and asthma but also for other conditions such as pain and high blood pressure. "We demonstrated that when one of the systems goes awry, so does the other," said Stam...
