Happy 19th Birthday TACC!June 1st marked the 19th anniversary of the founding of the Texas Advanced Computing Center. We couldn't have made it this far without the talented, dedicated, and hardworking team that continues to overcome whatever challenges we face in our mission to power discoveries that change the world. | ||||
 Getty Images | How Supercomputers Are Getting Us Closer to a COVID-19 Vaccine"Supercomputers are enabling a vastly accelerated pace by which scientists can conduct research and collect and analyze data. Never have they proven their value to society more than during this COVID-19 pandemic." Writing in The Hill, TACC Executive Director Dan Stanzione shares his perspective on efforts to combat the virus. | |||

They identified the 600 most likely to be effective at disrupting SARS-CoV-2, which are currently being tested at high-containment labs at Boston University, Texas A&M, and UT Medical Branch. | |||

Researchers at the University of Utah are using supercomputers at TACC to model more accurate force fields and predict the characteristics of novel drugs that can disrupt the COVID-19 virus. | |||

UT Austin social science researchers are using the dataset to explore misinformation and racist messaging on Twitter, and to understand how communities share (or don't share) information. | |||

Simulations of the spike proteins on TACC supercomputers show there are significant behavioral differences between the two strains, which could have major implications for how we treat the virus. | |||
 A computational pipeline to screen drugs for cardiotoxicity has been developed with the use of TACC supercomputers. [Credit: Yang et al., Circulation Research] | Supercomputing Drug Screening for Deadly Heart ArrhythmiasScientists have developed a new way to screen drugs for induced arrhythmias by computationally analyzing their chemical structures. Simulations on TACC supercomputers and other systems around the country helped scientists study interactions of drug molecules with an ion channel protein embedded in a hydrated lipid bilayer. The research could help make safer pharmaceuticals. | |||
 Texascale Days Showcases Potential of Frontera for Large-Scale Simulation and ModelingIn March, seven research teams were provided exclusive access to Frontera, TACC's leadership-class supercomputer, to solve large problems in astronomy, biology, and physics. The event is a stepping stone to the science problems of tomorrow and the HPC resources required to investigate them. |  Welcome to TACC's Frontera Fellowship AwardeesThe Frontera Fellowship program provides a year-long opportunity for talented graduate students to compute on the most powerful academic supercomputer in the world and collaborate with experts at TACC. From simulations of black holes to hurricane storm surge models, these up-and-coming scientists will have an opportunity to conduct research at a scale rarely accessible to students. |  Work @ TACCWorking at TACC means being part of a dynamic and exciting environment, where talented individuals pursue their interests, engage their imaginations, and work at the forefront of computational research. Working with us also means living in Austin, an exceptional city that thrives on innovation, culture, and creativity. | ||||
