A nuclear density map of the bacterial enzyme HpMTAN’s active site reveals the locations of the hydrogen atoms, including the unexpected observation of a hydrogen ion positioned midway between adenine and D198 residue.
Neutron analysis at the Department of Energy’s Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer. Understanding the details of this enzyme, and thus the Helicobacter pylori bacteria’s metabolis...
ORNL researchers have discovered a new type of quantum critical point, a new way in which materials change from one state of matter to another. Featured here are researchers Lekh Poudel (left), Andrew Christianson and Andrew May.
When matter changes from solids to liquids to vapors, the changes are called phase transitions. Among the most interesting types are more exotic changes—quantum phase transitions—where the strange properties of quantum mechanics can bring about extraordinary changes in curious way...
