Scientists capture the elusive structure of essential digestive enzyme (JACS)

By Tien Nguyen, Department of Chemistry Using a powerful combination of techniques from biophysics to mathematics, researchers have revealed new insights into the mechanism of a liver enzyme that is critical for human health. The enzyme, phenylalanine hydroxylase, turns the essential amino acid phenylalanine – found in eggs, beef and many other foods and as … Continue reading Scientists capture the elusive structure of essential digestive enzyme (JACS)

Theorists smooth the way to solving one of quantum mechanics oldest problems: Modeling quantum friction (J. Phys. Chem. Letters)

By: Tien Nguyen, Department of Chemistry Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters. “It was truly a most … Continue reading Theorists smooth the way to solving one of quantum mechanics oldest problems: Modeling quantum friction (J.

PPPL scientists challenge conventional understanding and improve predictions of the bootstrap current at the edge of fusion plasmas (Physics of Plasmas)

By John Greenwald, PPPL Office of Communications Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have challenged understanding of a key element in fusion plasmas. At issue has been an accurate prediction of the size of the “bootstrap current” — a self-generating electric current — and an understanding of what … Continue reading PPPL scientists challenge conventional understanding and improve predictions of the bootstrap current at the edge of fusion plasmas (Physics of Plasmas)
