Pick your poison. It can be deadly for good reasons such as protecting crops from harmful insects or fighting parasite infection as medicine — or for evil as a weapon for bioterrorism. Or, in extremely diluted amounts, it can be used to enhance beauty.

The 75th anniversary of the final voyage of the USS Indianapolis and her brave crew is Thursday, July 30. The US Navy warship was on a top-secret mission across the Pacific Ocean to deliver war materials that marked the conclusion of the Manhattan Project.

ORNL researchers are leading virtual STEM outreach activities, such as an Internet of Things demonstration in which participants in ORCSGirls control an LED board remotely.

COVID-19 has upended nearly every aspect of our daily lives and forced us all to rethink how we can continue our work in a more physically isolated world.

Recent research involving Oak Ridge National Laboratory’s Spallation Neutron Source demonstrates crystal-like heat conduction in a solid-liquid hybrid, AgCrSe2.

Research by an international team led by Duke University and the Department of Energy’s Oak Ridge National Laboratory scientists could speed the way to safer rechargeable batteries for consumer electronics such as laptops and cellphones.

Biological membranes, such as the “walls” of most types of living cells, primarily consist of a double layer of lipids, or “lipid bilayer,” that forms the structure, and a variety of embedded and attached proteins with highly specialized functions, including proteins that rapidly and selectively transport ions and molecules in and out of the cell.

Scientific discovery can come from anywhere, but few researchers can say the answers to their questions would come from the pea-sized bones in the head of a six-foot-long, 200-pound prehistoric freshwater fish. In a unique pairing of biology and neutron science, researchers from...

Unexpected results from a neutron scattering experiment at the Department of Energy’s Oak Ridge National Laboratory could open a new pathway for the synthesis of novel materials and also help explain the formation of complex organic structures observed in interstellar space. I...
A team from ORNL, Indiana University and Max Planck Institute in Germany has implemented a technique with Wollaston prisms to expand the capabilities currently available at ORNL’s High Flux Isotope Reactor instrument HB-1.
For the first time since 2011, scientific users of Oak Ridge National Laboratory’s High Flux Isotope Reactor were able to take advantage of a seventh cycle, allowing for 25 extra days of neutron production and available time for new experiments on HFIR’s 12 beam lines in fiscal ye...
