ORNL is a multiprogram science and technology laboratory managed
for the U.S. Department of Energy by UT-Battelle, LLC. Scientists
and engineers at ORNL conduct basic and applied research and development
to create scientific knowledge solutions that strengthen the nation's
leadership in key areas of science; increase the availability
of clean, abundant energy; restore and protect the environment;
and contribute to national security.
ORNL also performs other work for the Department of Energy, including
isotope production, information management, and technical program
management, and provides research and technical assistance to
Researchers from Washington University in St. Louis and ORNL are using neutrons to study what happens when cyanobacteria cell samples are starved for nitrogen. They are especially interested in how this process affects phycobilisomes, large antenna protein complexes in the cells that harvest light for photosynthesis.
Researchers from ORNL's Neutron Sciences Directorate are conducting a series of experiments to better understand how resistant bacteria use enzymes called beta-lactamases to break down the beta-lactam class of antibiotics.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
