Exascale’s New Frontier: WarpX

PI: Jean-Luc Vay, Accelerator Technology & Applied Physics Division at Lawrence Berkeley National Laboratory In 2016, the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (10¹⁸) or more calculations per second. That meant…

Advancing Nanoscience Through Largescale MD Simulations

Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to products with inherently…

New Insights Into a Shapeshifting Protein Complex

Transcription factor IIH, or TFIIH, pronounced “TF two H,” is a veritable workhorse among the protein complexes that control human cell activity. It plays critical roles both in transcription — the highly regulated enzymatic synthesis of RNA from a DNA template — and in the repair of damaged DNA. But…

Reaching a New Summit for Supernova Simulations

As a result of largescale 3D supernova simulations conducted on the Oak Ridge Leadership Computing Facility’s Summit supercomputer by researchers from the University of Tennessee and Oak Ridge National Laboratory, astrophysicists now have the most complete picture yet of what gravitational waves from exploding stars look like. This is critical…

Predicting the Future of Fission Power

As renewable sources of energy such as wind and sun power are being increasingly added to the country’s electrical grid, old-fashioned nuclear energy is also being primed for a resurgence. For the past 20 years, fission reactors have produced a nearly unchanging portion of the nation’s electricity: around 20%. But…

Distilling How Water Turns into Ice

Among the mysteries of science that continue to elude researchers, one stands apart in its vexing simplicity: ice. Yes, frozen water. Water’s transformation from liquid to solid is actually a complex process of nature that scientists have named—nucleation—yet do not fully understand. However, Princeton University researchers have taken trailblazing steps…
