Feb. 17, 2008—When you check into a hospital, the odds are one in ten that you will become infected with a strain of antibiotic-resistant bacteria as a result of your stay. That is because the problem of drug-resistance has become endemic in today\'s hospitals despite the best efforts of the medical profession. In the United States alone this currently causes about 100,000 deaths per year.
Feb. 7, 2008—Shrews are tiny mammals that have been widely characterized as simple and primitive. This traditional view is challenged by a new study of the hunting methods of an aquatic member of the species, the water shrew.
Dec. 18, 2007—A team of Vanderbilt researchers has demonstrated for the first time that a new type of gene therapy, called RNA interference, can heal a genetic disorder in a live animal.
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.
