Dec. 6, 2007—It‘s a rare case of all light and no heat: A new study reports that a laser can be used to switch a film of vanadium dioxide back and forth between reflective and transparent states without heating or cooling it.
Nov. 21, 2007—There is a new twist on the question of how biological clocks work. In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery.
Nov. 2, 2007—Vanderbilt‘s Writing Studio will host a public lecture by Sally Adee, a science writer who lives in Baltimore, Md., and specializes in reporting on geology, solid-state physics, nuclear energy and defense technology.
Oct. 31, 2007—Two Vanderbilt faculty members √± Peter T. Cummings and Ellen H. Fanning √± have been elected as fellows of the American Association for the Advancement of Science (AAAS), an honor bestowed upon them by their peers.
Oct. 5, 2007—There are two aspects to creating an effective drug: finding a chemical compound that has the desired biological effect and minimal side-effects and then delivering it to the right place in the body for it to do its job.
Sep. 27, 2007—Dramatic daily variations in the cockroach's learning ability were discovered by a new study performed by Vanderbilt University biologists and published online this week in the Proceedings of the National Academy of Sciences.
Sep. 20, 2007—When biological molecules kiss, a new kind of biosensor can tell. A new and deceptively simple technique has been developed by chemists at Vanderbilt University that can measure the interactions between free-floating, unlabeled biological molecules including proteins, sugars, antibodies, DNA and RNA.
Sep. 11, 2007—For several months last spring, the Vanderbilt greenhouse held more members of a rare species of native sunflower than are known to exist in the wild.
Aug. 30, 2007—By mapping a specialized sensory organ that the malaria mosquito uses to zero in on its human prey, an international team of researchers has taken an important step toward developing new and improved repellants and attractants that can be used to reduce the threat of malaria, generally considered the most prevalent life-threatening disease in the world.
Jun. 7, 2007—In a way, nanotubes are nature's smallest candles. These tiny tubes are constructed from carbon atoms and they are so small that it takes about 100,000 laid side-by-side to span the width of a single human hair.
May. 24, 2007—Fast forward to a civilization about three trillion years in the future. Astronomers at that time equipped with instruments equal to those of today would likely come to a much different conclusion about the basic nature of the universe, one that harks back to static models that were popular at the turn of the century.
