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...

CCSI scientist Jiafu Mao, of the Terrestrial Systems Modeling group in the Environmental Sciences Division, parlayed his interest in physics and mathematics as a student in China into a field of study he has always found interesting

Ramakrishnan “Ramki” Kannan loves the excitement and challenge of working at Oak Ridge National Laboratory, home to Titan.

Supercomputers like Oak Ridge National Laboratory’s Titan are advancing science at a frenetic pace and helping researchers make sense of data that could have easily been missed, says Ramakrishnan “Ramki” Kannan. Kannan, a computer scientist who came to ORNL in March 2016 after ...

Award-winning mammalian geneticist Lee Russell (right, in a 2014 photo) is the namesake of the Liane B. Russell Fellowship for early career scientists at ORNL.
The famed mouse colony once housed at the Department of Energy's Oak Ridge National Laboratory had a prominent role in groundbreaking autoimmune disease research recently recognized with an award from the Royal Swedish Academy of Sciences. The academy recently awarded its prest...
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...
Kai Xiao
Kai Xiao's work as a staff scientist at ORNL’s Center for Nanophase Materials Science gives him access to some of the world’s most powerful tools to investigate materials as small as one-billionth of a meter, or at the nanoscale. He joins multidisciplinary teams to explore a va...

At the confluence of energy and ecology is where Henriette “Yetta” Jager has found her calling. A senior scientist in the Environmental Sciences Division, Yetta uses models to look for win-win opportunities to produce more energy without harming fish and wildlife. Yetta’s research for the US D...

The Transforming Additive Manufacturing through Exascale Simulation project (ExaAM) is building a new multi-physics modeling and simulation platform for 3D printing of metals

Oak Ridge National Laboratory experts are playing leading roles in the recently established Department of Energy’s (DOE’s) Exascale Computing Project (ECP), a multi-lab initiative responsible for developing the strategy, aligning the resources, and conducting the R&D necessary to achieve the nation’s imperative of delivering exascale computing by 2021.
