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…

Learning With the Flow

The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…

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…

Lab Experiments Support the COVID-19 Bradykinin Storm Theory

A new paper published in Nature Communications adds further evidence to the bradykinin storm theory of COVID-19’s viral pathogenesis—a theory that was posited 2 years ago by a team of researchers led by Systems Biologist Dan Jacobson at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL). At…

Weaving wonders

Ounce for ounce, carbon fiber could quickly become the wonder material of the future. The material, already used in a variety of products, boasts densities comparable to plastic, strengths comparable to steel and versatilities comparable to rubber under the right conditions. Its fibers, spun from organic carbon polymer strands thinner…
