Researchers reveal how microbes cope in phosphorus-deficient tropical soil

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A team led by the Department of Energy's Oak Ridge National Laboratory has uncovered how certain soil microbes cope in a phosphorus-poor environment to survive in a tropical ecosystem. Their novel approach could be applied in other ecosystems to study various nutrient limitations and inform agriculture and terrestrial biosphere modeling.

ORNL researchers use Titan to accelerate design, training of deep learning networks

DOE/Oak Ridge National Laboratory
Business Announcement

For deep learning to be effective, existing neural networks to be modified, or novel networks designed and then 'trained' so that they know precisely what to look for and can produce valid results. This is a time-consuming and difficult task, but one that a team of ORNL researchers recently demonstrated can be dramatically expedited with a capable computing system.

New study visualizes motion of water molecules, promises new wave of electronic devices

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics. Oak Ridge National Laboratory used a high-resolution inelastic X-ray scattering technique to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, which determines a liquid's resistance to flow or to change shape.

Neutrons track quantum entanglement in copper elpasolite mineral

DOE/Oak Ridge National Laboratory

A research team including Georgia Institute of Technology professor Martin Mourigal used neutron scattering at Oak Ridge National Laboratory to study copper elpasolite, a mineral that can be driven to an exotic magnetic state when subjected to very low temperatures and a high magnetic field.
