Probing DNA for cancer therapies

Intercalators can change the structure of DNA and lead to genetic abnormalities that cause cell death. They also play an important role in anti-cancer drugs. A group of researchers are investigating intercalators and their effect on DNA using computational simulations and experiments. Through XSEDE, the researchers can perform molecular dynamics to capture details that can't be seen with experimentation, using advanced computing resources like Stampede, Comet, and Bridges. The researchers are now extending their research to another cancer drug to better understand the fundamental mechanisms of a cancer drug on DNA structure and cell death. Read more

Wild Things

The tropical Sumatran rhino almost certainly has a lot to tell us about evolutionary survival. Its closest relative is the Ice Age wooly rhinoceros of Eurasia. Almost certainly, its ancestors started out as a cool-weather grassland species that adapted to a warmer and wetter climate. The Narcissus flycatcher, meanwhile, is a bird with multiple personalities—part of its population would migrate, the rest wouldn't. A team led by Herman Mays and Jim Denvir of Marshall University decided to apply advanced sequencing techniques on XSEDE resources to create the first genetic sequence for both species. Their aim is to understand how climate changes, evolutionary bottlenecks and genes interact to make profound changes in behavior and habitat. Read more

XSEDE helps researcher read echoes

Meers Oppenheim's research team discovered that "radar echoes" appear at an altitude of about 150 kilometers, and fall to about 20 km during the day, before going back up again. Oppenheim used XSEDE's Stampede—one of the fastest supercomputers in the world housed at Texas Advanced Computing Center. And he also used Extended Collaborative Support Service (ECSS), a help service within XSEDE that partners researchers with computational science experts for periods of time ranging from a few months to a year.

'Hurricane hunter' data improves hurricane intensity predictions

Yonghui Weng used XSEDE and convection-permitting ensemble data assimilation to understand "hurricane hunter" data to improve hurricane intensity forecasts. Some of the techniques have already been adopted by NOAA and other federal agencies. Read more

Achieving innovation through collaboration – and diversity

Dr. Pamela McCauley, an internationally recognized ergonomics and biomechanics expert and tenured professor who leads the Ergonomics Laboratory at the University of Central Florida, has one message for today's scientists and engineers: innovation is the key to our collective future but it cannot be done without collaboration that truly embraces diversity.

NSF awards $15M to create SGCI

The NSF has awarded a five-year $15 million grant to establish a Science Gateways Community Institute. The institute will accelerate the development and application of highly functional, sustainable science gateways that address the needs of researchers across the full spectrum of NSF directorates. "We see the services offered by SGCI dovetailing nicely with those offered by XSEDE," said XSEDE co-PI Nancy Wilkins-Diehr. Read more

Diversity shines at XSEDE16 conference

The first five years of the NSF-funded XSEDE project culminated in an exciting and enlightening week's worth of technical talks and presentations about high-performance computing (HPC) services and resources. The XSEDE16 conference where these were showcased also gave underrepresented groups an opportunity to be exposed to HPC and a plethora of experts in nearly every field of research. Read more
