A classic study from more than 60 years ago suggesting that males are more promiscuous and females more choosy in selecting mates may, in fact, be wrong, say life scientists who are the first to repeat the historic experiment using the same methods as the original. (more…)
Pity the poor Neon light – for so long the king of illuminated displays, the Las Vegas favourite, the flickering indicator of all that was exciting, glamorous and sleazy. But now Neon’s time in the limelight (pardon the pun) is over – environmental concerns, expense and impracticality have all led to a reduction in the requirement for Neon’s services. But the main culprit responsible for Neon’s demise is the rise in the quality and variety of electroluminescent lighting options available. In particular, the versatility of electroluminescent (or EL) wire means that it’s now possible to create lighting designs and displays of a quality and intricacy that Neon can’t compete with. (more…)
A coating of selenium nanoparticles significantly reduces the growth of Staphylococcus aureus on polycarbonate, a material common in implanted devices such as catheters and endotracheal tubes, engineers at Brown University report in a new study.
PROVIDENCE, R.I. [Brown University] — Selenium is an inexpensive element that naturally belongs in the body. It is also known to combat bacteria. Still, it had not been tried as an antibiotic coating on a medical device material. In a new study, Brown University engineers report that when they used selenium nanoparticles to coat polycarbonate, the material of catheters and endotracheal tubes, the results were significant reductions in cultured populations of Staphylococcus aureus bacteria, sometimes by as much as 90 percent.

Synopsis
Peter Parker, an outcast high schooler who was abandoned by his parents as a boy, leaving him to be raised by his Uncle Ben and Aunt May. Like most teenagers, Peter is trying to figure out who he is and how he got to be the person he is today.

James Watson, a UA anthropologist, has published chapters describing how long-term environmental trends encourage stable adaptations within local environments.
Human/environment interactions have a history as long as the existence of our species on the planet.
Hominid ancestors began polluting their environment nearly 700,000 years ago with the control of fire, and humans have not looked back since.
The modern phenomenon of global warming is very likely the direct result of human pollution and destruction of the environment, said James Watson, a University of Arizona assistant professor in the School of Anthropology. (more…)

Researchers at Yale School of Medicine have zeroed in on a set of neurons in the part of the brain that controls hunger, and found that these neurons are not only associated with overeating, but also linked to non-food associated behaviors, like novelty-seeking and drug addiction.
Published in the June 24 online issue of Nature Neuroscience, the study was led by Marcelo O. Dietrich, postdoctoral associate, and Tamas L. Horvath, the Jean and David W. Wallace Professor of Biomedical Research and chair of comparative medicine at Yale School of Medicine.
In attempts to develop treatments for metabolic disorders such as obesity and diabetes, researchers have paid increasing attention to the brain’s reward circuits located in the midbrain, with the notion that in these patients, food may become a type of “drug of abuse” similar to cocaine. Dietrich notes, however, that this study flips the common wisdom on its head. (more…)
