Conceptual art connects the atomic underpinnings of the neutron-rich calcium-48 nucleus with the Crab Nebula, which has a neutron star at its heart. Zeros and ones depict the computational power needed to explore objects that differ in size by 18 orders o
An international team led by Gaute Hagen of the Department of Energy’s Oak Ridge National Laboratory used America’s most powerful supercomputer, Titan, to compute the neutron distribution and related observables of calcium-48

Inspections will play a crucial role in the decisions to extend operating licenses for many of the nation’s aging nuclear power plants, and Oak Ridge National Laboratory has a tool that could help. “The question that needs to be answered is whether the concrete structures th...

High-resolution imaging of materials produces complex, copious data. Researchers at Oak Ridge National Laboratory are developing a visual analytics system that could essentially “look over a scientist’s shoulder,” learning from human actions and improving its predictions of ...

Award-winning author Richard Rhodes, who wrote the book “The Making of the Atomic Bomb,” told an Oak Ridge audience that despite new forms of clean energy being developed, coal is still the world’s primary producer of energy, listing several reasons. “In a world...

Harvesting oil, mitigating subsurface contamination, and sequestering carbon emissions share a common thread—they deal with multiphase flows, or situations where materials are flowing close together in different states (solids, liquids, or gases) or when the flow is comprised ...
With a nano-ring-based toroidal trap, cold polar molecules near the gray shaded surface approaching the central region may be trapped within a nanometer scale volume.
Single atoms or molecules imprisoned by laser light in a doughnut-shaped metal cage could unlock the key to advanced storage devices, computers and high-resolution instruments. In a paper published in Physical Review A, a team composed of Ali Passian of the Depa...

When it’s up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other hand, will be small and very cold. Pellets of frozen gas will be shot int...

Viruses are tiny—merely millionths of a millimeter in diameter—but what they lack in size, they make up in quantity.
