For two molecules on blind date, new method predicts potential for attraction or repulsion Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs. The research is reported as a communication in the April 27 issue of the...

A controversial idea that sense of smell can be explained by quantum physics is gaining traction in the science world, according to researchers. Researchers, reporting at the American Physical Society meeting in Dallas, say the key to proving how such a theory would work revolves around tiny packets of energy -- or quanta -- lost by electrons. The scientists performed experiments using tiny wires and showed that as electrons move on proteins within the nose, odor molecules could absorb...

Protein molecules inside cells are constantly reorganizing themselves, driven by very tiny forces exerted by all the other molecules in their crowded environment. Most experimental techniques and theoretical/computational models are necessarily built around much greater driving forces. A new theoretical model reported in the Journal of Chemical Physics investigates the unfolding of fibronectin under gentler conditions. "Typical models study very fast processes and consume a lot of CPU time,"...

A new paper by University of Notre Dame physicist Boldizsár Jank³ and colleagues offers an important new understanding of an enduring mystery in chemical physics. More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in Bohr's...

Research reported in The Journal of Chemical Physics, which is published by the American Institute of Physics, provides the first real-time measurements of the time dependence of the individual steps of dissociation of a complex consisting of two rare gas atoms and a halogen molecule. "The goal of this work is to provide a test case for quantum dynamics theory," says author Kenneth C. Janda of the University of California, Irvine. "It is a problem that is easy, but not too easy, in the sense...

Word of the Day
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
