Americans place high value on butterfly royalty. A just-released study suggests they are willing to support monarch butterfly conservation at high levels, up to about $6.5 billion dollars if extrapolated to all US households. If even a small percentage of the population acted upon this reported willingness, the cumulative...

An unintended legacy of California's gold rush, which began in 1848, endures today in the form of mercury-laden sediment. New research by Michael Singer, associate researcher at UC Santa Barbara's Earth Research Institute, shows that sediment-absorbed mercury is being transported by major floods from the Sierra Nevada mountains...

Physical activity is being increasingly recognized as an effective tool to treat depression. Ph.D. candidate George Mammen's review published in the October issue of the American Journal of Preventive Medicine has taken the connection one step further, finding that moderate exercise can actually prevent episodes of depression...

Columbia Engineering researchers have developed a new approach to designing novel nanostructured materials through an inverse design framework using genetic algorithms. The study, published in PNAS's Oct. 28 Early Online edition, is the first to demonstrate the application of this methodology to the design of self-assembled...

In a pair of landmark studies that exploit the genetic sequencing of the "missing link" cold virus, rhinovirus C, scientists at the University of Wisconsin-Madison have constructed a three-dimensional model of the pathogen that shows why there is no cure yet for the common cold. Fuente :...

Psychology and behavioral economics have experimentally identified a laundry list of common biases that cause people to act against their own apparent interests. One of these biases -- the mere fact of possessing something raises its value to its owner -- is known as the "endowment effect." A new interdisciplinary study from...

A research team led by UC Riverside biogeochemists reports that oxygen-free and hydrogen sulfide-rich waters extended across roughly five percent of the ocean 93.9 million years ago -- far more than the modern ocean's 0.1 percent but much less than previous estimates for this event. Across this event, a major biological...

A University of Colorado Cancer Center study published in the journal PLoS One shows that when colorectal cancer is targeted by the drug bevacizumab (Avastin), tumors may switch dependence from VEGF-A, which is targeted by the drug, to related growth factors in including VEGF-C, VEGF-D and placental growth factor. This change...
