Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

Fungal ‘Bouncers’ Patrol Plant-Microbe Relationship

By Stephanie Seay, ORNL A new computational framework created by Oak Ridge National Laboratory researchers is accelerating their understanding of who's in, who's out, who’s hot and who's not in the soil microbiome, where fungi often act as bodyguards for plants, keeping friends close and foes at bay. The research…

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…

ORNL Supercomputing Resources Support Simulation of Influenza Virus Showing Universal Vaccine Promise

According to the World Health Organization, each year influenza infects an estimated 1 billion people worldwide. Between 3 and 5 million of these cases are severe, and up to 650,000 cases result in influenza-related respiratory deaths. Seasonal flu vaccines are reformulated each year to match the dominant strains, and when…

Predicting Protein Targets and the Molecules that Bind with Them

When the COVID-19 pandemic brought the world to a standstill in 2020, pharmaceutical companies countered with remarkable speed to develop mRNA vaccines by the end of that year. Creating new antiviral drugs to treat those who became infected by the deadly coronavirus took about another year of work—astoundingly quick compared…

Solving the Protein Puzzle

A simple scoop of soil or water can hold an entire ecosystem–potentially millions or more microscopic organisms and the countless proteins they rely on to survive. Computations performed at the U.S. Department of Energy’s Oak Ridge National Laboratory could help count, sort and catalog each of those proteins in record…

Supercomputing for Swift Protein Modeling

Uncovering the molecular structures of proteins can help scientists elucidate biological functions of proteins and search for drug candidates for diseases. To better understand proteins, scientists can use imaging techniques to probe their molecular structures. However, many imaging techniques fall short of capturing details at the atomic level. That’s why…
