For decades, biologists have believed a key enzyme in plants had one function—produce amino acids, which are vital to plant survival and also essential to human diets. But for Wellington Muchero, Meng Xie and their colleagues, this enzyme does more than advertised. They had run a series of experiments on poplar plants that consistently revealed mutations in a structure of the life-sustaining enzyme that was not previously known to exist.

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.

As part of the Next-Generation Ecosystem Experiments Arctic project, scientists use a hydraulic rig to extract soil samples from the frozen soil in Utqiaġvik, Alaska.

Digging into the Arctic tundra, scientists at Oak Ridge National Laboratory have uncovered new insights into how quickly microorganisms break down organic matter in warming Arctic soil—a process that releases stored carbon as carbon dioxide and methane. The team studied soil extracted...

New exascale earth modeling system for energy
A new earth modeling system will use advanced computers and have weather scale resolution to simulate aspects of Earth’s variability and anticipate decadal changes that will critically impact the United States’ energy sector. The Energy Exascale Earth System Model, or E3SM, relea...
