An illustration of the dopamine transporter in its outward- (left) and inward-opening (right) state. Note that the inward opening has brought about an outward closing and change in the number of water molecules (blue, pink spheres) inside and outside the

In an era of instant communication, perhaps no message-passing system is more underappreciated than the human body. Underlying each movement, each mood, each sight, sound, or smell, an army of specialized cells called neurons relays signals that register in the brain and connect us to our environment.

A simulation of combustion within two adjacent gas turbine combustors. GE researchers are incorporating advanced combustion modeling and simulation into product testing after developing a breakthrough methodology on the OLCF’s Titan supercomputer.

In the United States, the use of natural gas for electricity generation continues to grow. The driving forces behind this development? A boom in domestic natural gas production, historically low prices, and increased scrutiny over fossil fuels’ carbon emissions. Though coal still acco...

Department of Energy national lab researchers found strain dramatically influences low-temperature oxygen electrocatalysis on perovskite oxides, enhancing bifunctional activity essential for fuel cells and metal–air batteries.

Catalysts make chemical reactions more likely to occur. In most cases, a catalyst that’s good at driving chemical reactions in one direction is bad at driving reactions in the opposite direction. However, a research team led by the Department of Energy’s Oak Ridge National Laboratory ...

Interpreting the results of collision induced dissociation (CID) experiments, simulations on Titan predict the formation of an unusually bonded uranium-nitrosyl molecule. Credit: J. Am. Chem. Society. DOI: 10.1021/jacs.5b02420
Radioactive materials have long been a part of American history—from the Manhattan Project to the development of nuclear power. The materials central to these innovations are actinides, or elements 89–103 on the periodic table that release large amounts of energy when atoms are spli...
In unbound calyx[4]pyrrole, two pyrrole “petals” are flipped up and two, down.

Atomic charges in chemical solutions are like Switzerland—they strive for neutrality. The tendency to balance charges drives dynamics when charged atoms or molecules, called ions, are present in solutions. Recently, researchers at the Department of Energy’s Oak Ridge National Laborat...

Lipid molecules have split personalities—one part loves water, whereas the other avoids it at all costs. Lipids make up cell membranes, the frontline defense in preventing cellular access to bacterial and viral invaders. Many researchers believe that the membrane is not just a scaf...
Oak Ridge National Laboratory researchers made a molecule that could selectively bind to metals in the middle of the lanthanide series.

Rare earth elements are metals used in technologies from wind turbines and magnetic resonance imaging agents to industrial catalysts and high-definition televisions. Most are lanthanides, elements with atomic number from 57 to 71, lanthanum to lutetium, in the periodic table. The la...

Oak Ridge National Laboratory researchers re-evaluated used nuclear fuel rods from a commercial reactor and reduced data uncertainties by an order of magnitude compared with previous measurements taken at a different lab.

Nearly 100 commercial nuclear reactors supply one-fifth of America’s energy. For each fuel rod in a reactor assembly, only 5 percent of its energy is consumed before fission can no longer be sustained efficiently for power production and the fuel assembly must be replaced. Power plan...

The global marketplace demands constant improvements in performance and efficiency of aircraft engines, power turbines and other modern mainstays of energy technology. This progress requires advanced structural materials, such as ceramic composites and metal alloys with higher-t...

Ask a biofuel researcher to name the single greatest technical barrier to cost-effective ethanol, and you’re likely to receive a one-word response: lignin. Cellulosic ethanol—fuel derived from woody plants and waste biomass—has the potential to become an affordable, renew...
