New York Medical College researchers publish new findings on the spread of lyme disease bacteria
The results of a five-year study, published this week in the Annals of Internal Medicine by researchers at New York Medical College, reveal intriguing new data on the spread of the Lyme disease bacteria through the blood stream. The ability to find the Lyme spirochete--the tick-borne agent responsible--in the blood is itself an achievement because existing methods of culturing blood were not sensitive enough to detect its presence until College researchers developed a new technique, which they used in the study.
Leading the study was Gary P. Wormser, M.D., professor of medicine, director of the Division of Infectious Diseases and vice chairman of the Department of Medicine. "If Lyme disease stayed in the skin it would be a completely different and rather inconsequential infection--but it doesnt," Dr. Wormser explained. "The causative agent of Lyme disease can spread from its entry point at the tick bite site through the blood to distant sites such as the brain, heart, and joints. This study answers questions that have never been answered before and raises others that will likely stimulate future studies on Lyme disease."

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
