Speeding Toward the Future of Fusion

In 1934, physicist Ernest Rutherford and his colleagues produced the first fusion reaction—the fusing of light nuclei to release energy—in a laboratory by converting deuterium, a heavy hydrogen isotope, to helium. Since then, scientists have built increasingly efficient fusion energy devices with a goal to achieve net fusion energy, or…

Virtual Universes

Using Summit, the world’s most powerful supercomputer housed at Oak Ridge National Laboratory, a team led by Argonne National Laboratory ran three of the largest cosmological simulations known to date. They modeled nearly two trillion particles in each simulation to trace matter distribution and generated a total of eight petabytes…

New Geometric Model Improves Predictions of Fluid Flow in Rock

Deep beneath the Earth’s surface, oil and groundwater percolate through gaps in rock and other geologic material. Hidden from sight, these critical resources pose a significant challenge for scientists seeking to evaluate the state of such two-phase fluid flows. Fortunately, the combination of supercomputing and synchrotron-based imaging techniques enables more…
