Predicting the perfect predator

Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has created a computer model that in combination with quarantined research tests he believes will be able to predict the perfect predator -- a pest that can be introduced into a forested area that will help reduce the garlic mustard population.

   In the timeless quest for healthier, younger looking skin, scientists made an important discovery with implications ranging from helping doctors develop more natural looking bioengineered skin grafts to helping cosmetics companies develop new products for the "perfect" sunless tan. The research study, published in The FASEB Journal's September print issue, shows for the first time how to manipulate skin tone and color using cells previously thought to play no significant role in this function.

3. Pressured by predators, lizards see rapid shift in natural selection
   11-16-2006 · EurekAlert!
   Countering the widespread view of evolution as a process played out over the course of eons, evolutionary biologists have shown that natural selection can turn on a dime -- within months -- as a population's needs change. In a study of island lizards exposed to a new predator, the scientists found that natural selection dramatically changed direction over a very short time, within a single generation, favoring first longer and then shorter hind legs.

   According to a recent study, predicting the impact of climate change on organisms is more complicated than simply looking at species northern and southern range limits. Studying the California Sea Mussel -- Mytilus californianus, Brian Helmuth (University of South Carolina) and colleagues from the University of California-Santa Barbara, the University of British Columbia-Vancouver and Oregon State University measured body temperatures of this mussel along most of its range, from Washington to Southern California.

8. Taming tiny, unruly waves for nano optics
   10-08-2007 · EurekAlert!
   Nanoscale devices present a unique challenge to any optical technology -- there's just not enough room for light to travel in a straight line. As light waves are pressed through surfaces only a few nanometers apart (smaller than their wavelength), they become unstable and difficult to predict. But Georgia Tech researchers have discovered a method of predicting the behavior of light on the nanoscale during radiation heat transfer, opening the door to the design of a spectrum of new nanodevices and technologies.

10. The dark side of nature: The crime was almost perfect
    12-20-2006 · EurekAlert!
    Nature has again thrown astronomers for a loop. Just when they thought they understood how gamma-ray bursts formed, they have uncovered what appears to be evidence for a new kind of cosmic explosion. These seem to arise when a newly born black hole swallows most of the matter from its doomed parent star.
