Oak Ridge National Laboratory launches Summit supercomputer.

The U.S. Department of Energy’s Oak Ridge National Laboratory today unveiled Summit as the world’s most powerful and smartest scientific supercomputer.

Kaushik Biswas is a mechanical engineer in the Building Envelope & Urban Systems Research Group at Oak Ridge National Laboratory.

Inspiration often strikes in the unlikeliest of places and for Kaushik Biswas, a mechanical engineer in ORNL’s Building Envelope & Urban Systems Research Group, a moment spent enjoying entertainment led to the idea of developing self-healing vacuum panels for buildings. “I was ...

Radiochemical technicians David Denton and Karen Murphy use hot cell manipulators at Oak Ridge National Laboratory during the production of actinium-227.

The Department of Energy’s Oak Ridge National Laboratory is now producing actinium-227 (Ac-227) to meet projected demand for a highly effective cancer drug through a 10-year contract between the U.S. DOE Isotope Program and Bayer.
