Carnivore Extinction Determined More By Biology Than Population Density - SpaceDaily Carnivores around the world are more at risk of extinction due to their own intrinsic biological attributes than from an increasing human population with whom they share their space, say scientists in a study published this week. Four traits in particular were associated with high extinction risk in carnivores: a small geographic distribution, low population density, high trophic level (position on the food chain), and long gestation period "This is a preliminary study, the first to examine a global level of extinction risk at the species level and at the same time consider biology's intrinsic influence. Now we intend to extend our methods to all 4,500 terrestrial mammals, to see if there are general predictors of extinction risk and that these rules apply between orders of animals." |

Mystery Of Nanoparticles Concealed In The Blink Of An Eye - SpaceDaily Quantum dots, also called nanocrystals, emit light in a rainbow of colors and are used in lasers, biological studies and other applications, but their tendency to blink hinders their technological value. Imagine the annoyance caused by a randomly flickering light bulb. "A quantum dot might blink for just a millionth of a second or it might blink for 15 minutes," said Matthew Pelton, a Research Associate at the University of Chicago's James Franck Institute. Pelton has found a way to measure the blinking that is simpler and faster than the conventional method. He will describe the measurements in the Aug. 2 issue of Applied Physics Letters with co-authors David Grier, now of New York University, and Philippe Guyot-Sionnest of the University of Chicago. |

Pressure Makes Pure Zirconium Glass - SpaceDaily Zirconium may not be a girl's best friend, but by squeezing the metal with roughly the same pressure needed to make diamonds, scientists at the University of California's Los Alamos National Laboratory made a pure glass that may prove nearly as valuable as real diamonds. The pure metallic glass formed by their high-pressure method holds promise for stronger, more stable materials for medical, sports and electronic products. "By using industrial pressure processes to make pure samples without the defects that appear in metallic glasses made the conventional way, we've identified a method with potentially important commercial applications." |
