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."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
