Release: ‘Smart’ sunglasses feature lenses that change color on demand EMBARGOED FOR RELEASE: Tuesday, March 27, 9:30 a.m., Central Time Lenses of ‘smart’ sunglasses can change color on demand. Get ready for the coolest, most colorful shades on the planet: Chemists at the University of Washington in Seattle say they are developing ‘smart’ sunglasses that will allow the wearer to instantly change the color of their lenses to virtually any hue of the rainbow by tuning a control knob on the glasses. The research will be presented in March at the American Chemical Society national meeting in Chicago.

Release: Contrast agent puts new light on diagnosing breast cancer EMBARGOED FOR RELEASE: Monday, March 26, 10:00 a.m., Central Time Hydroxyapatite crystals (pseudo-colored in purple), like those found in human breast cancer, are detected with high sensitivity using an optical contrast reagent and invisible near-infrared fluorescent light. Scientists in the laboratory of Dr. John Frangioni, M.D., Ph.D., associate professor of medicine and radiology at Harvard Medical School, have developed a contrast agent that selectively targets and highlights malignant micro-calcifications in the breast, while ignoring similar micro-calcifications found in benign breast conditions. The new, simpler way to detect malignant tumors will be described in March at the 233rd national meeting of the American Chemical Society in Chicago. (Photo courtesy of Dr. John Frangioni) |

Release: MRI contrast agent can detect heart attack in the making EMBARGOED FOR RELEASE: Tuesday, March 27, 8:00 p.m., Central Time An imaging-enhancement technique improved cholesterol detection by 79 percent in animal studies. Scientists at New York’s Mount Sinai Medical Center and the New York University School of Medicine have developed a new imaging technique that allows physicians to peer directly into patients' blood vessels and find dangerous cholesterol-filled plaques before they rupture and cause a heart attack. In animal tests, the new technique improved cholesterol detection by 79 percent. The research will be presented in March at the American Chemical Society national meeting in Chicago.

Release: MRI contrast agent can detect heart attack in the making EMBARGOED FOR RELEASE: Tuesday, March 27, 8:00 p.m., Central Time Schematic of a new heart disease contrast agent — a disc-like structure with 37pA peptides on the outside of a phospholipids bilayer. Scientists at New York’s Mount Sinai Medical Center and the New York University School of Medicine have developed a new imaging technique that allows physicians to peer directly into patients' blood vessels and find dangerous cholesterol-filled plaques before they rupture and cause a heart attack. In animal tests, the new technique improved cholesterol detection by 79 percent. The research will be presented in March at the American Chemical Society national meeting in Chicago.

Release: Molecular tools make the cut EMBARGOED FOR RELEASE: Sunday, March 25, 9:30 a.m., Central Time The scissor-like molecular machine extendsor folds in response to different wavelengths of light. Researchers in Japan have developed a pair of molecular-scale scissors that open and close in response to light. The tiny scissors are the first example of a molecular machine capable of mechanically manipulating molecules by using light, the scientists say. The scissors measure three nanometers in length, small enough to deliver drugs into cells or manipulate genes and other biological molecules. The research will be presented in March at the American Chemical Society meeting in Chicago. (Photo Courtesy of Takuzo Aida) |

Release: Ladybugs may be cute, but watch out when they get near wine EMBARGOED FOR RELEASE: Sunday, March 25, 2:00 p.m., Central Time Researchers have recently identified several chemicals produced by ladybugs that can taint the aroma and flavor of wine. Ladybugs produce a foul-smelling liquid that can be inadvertently processed along with grapes and taint the aroma and flavor of wine. Researchers at Iowa State University say they have identified several compounds that are responsible for the noxious odor, a finding that could lead to new strategies to eliminate the offensive compounds and improve wine quality. The study will be presented in March at the American Chemical Society national meeting in Chicago.(Courtesy of USDA Agricultural Research Service) |
