Oak Ridge National Laboratory researchers demonstrated that an electrochemical sensor paired with a transmitter not only detects propane leaks within seconds, but it can also send a signal to alert emergency services.

Scientists at Oak Ridge National Laboratory are closer to unlocking the secrets to better soil carbon sequestration by studying the tiny, sand-like silicon deposits called phytoliths in plants.

Although more than 92,000 dams populate the country, the vast majority — about 89,000 — do not generate electricity through hydropower.

Science has taken Melanie Mayes from Tennessee to the tropics, studying some of the most important ecosystems in the world.

ORNL scientists identified four amino acids key to signaling pathways in the PAN protein domain. Mutating any of those four resulted in disruption of the signal that tells cancer cells to multiply and spread in humans. Credit: Andy Sproles/ORNL, U.S. Dept. of Energy

Researchers at ORNL have definitively linked the function of a specific domain of proteins important in plant-microbe biology to a cancer trigger in humans, knowledge that had eluded scientists for decades.

To solve a long-standing puzzle about how long a neutron can “live” outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe.
