Determining details of attraction in mechanically-linked molecules allows chemists to fine-tune shapes, capabilities of supramolecules for improved and new polymers
Virginia Tech chemistry professor H.W. Gibson and his students have been able to take advantage of self assembly to create new chemical structures from mechanically-linked molecules. Gibson will give an invited talk in the Division of Polymer Chemistry at the 225th national meeting of the American Chemical Society March 2
A bacteriums ability to change its hairstyle may help in the effort to clean contaminated groundwater for drinking, according to Penn State researchers.
People are continually moving into places that are hot, sunny and arid where drinking water is in short supply, says R. Kramer Campen, Penn State graduate student in geosciences. “The imperative to find ways to clean groundwater is paramount,” he told attendees today (March 25) at the 225th American Chemical Society national meeting i
Researchers have discovered a gene that appears to be critical for maintaining a healthy sense of balance in mice. The study, led by a team at Washington University School of Medicine in St. Louis, appears in the April 1 issue of the journal Human Molecular Genetics and online March 24.
“Loss of balance is a significant problem in the elderly because it can lead to dangerous falls and injuries,” says one of the studys principal investigators, David M. Ornitz, M.D., Ph.D., professor of
One of the most powerful tools in today’s biological and medical science is the ability to artificially remove and add bits of DNA to an organism’s genome. This has helped scientists to understand problems caused by defective genes, for example, which have now been linked to thousands of human diseases. So far the technology has been limited to small segments of DNA. But four years ago, Francis Stewart and his colleagues at the European Molecular Biology Laboratory (Heidelberg) developed a new techn
Researchers hope to someday develop an enzyme to repair UV-damaged DNA in humans
Plants, pond scum, and even organisms that live where the sun doesnt shine have something that humans do not — an enzyme that repairs DNA damaged by ultraviolet (UV) light.
Cabell Jonas of Richmond, Va., an undergraduate honors student in biology at Virginia Tech, will report on the molecular details of the DNA-repair enzyme at the 225th national meeting of the American Chemical Society March
Finding an economical way to make a polyester commonly found in many types of bacteria into a plastic with uses ranging from packaging to biomedical devices is a long-held scientific goal. Such a polymer would be a “green” plastic, in that it would be biodegradable.
Geoffrey Coates, a professor of chemistry and chemical biology at Cornell University, Ithaca, N.Y., has partially achieved this goal by discovering a highly efficient chemical route for the synthesis of the polymer, known as po
