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…

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…
