One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards. By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern the positions of atoms within molecules without the restrictions imposed by X-ray diffraction (XRD) and...

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...

A paper by researchers at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful"”but tricky"”diagnostic technique for cell biology. The paper,* appearing this week in the Biophysical Journal, demonstrates that with improved hardware and better signal processing, a powerful form of molecular vibration spectroscopy can quickly deliver detailed molecular maps of the contents of cells without damaging them. Earlier studies have...
