Computer Models Reveal Quantum Effects in Biological Oxygen Transport

July 18, 2014 3:41 pm | by Trinity College | News | Comments

Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well-characterized protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the team has shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.

Auto Industry Gets Serious about Lighter Materials

June 10, 2014 2:09 pm | by Dee-Ann Durbin, AP Auto Writer | News | Comments

While hybrids and electrics may grab the headlines, the real frontier in fuel economy is the switch to lighter materials. Automakers have been experimenting for decades with lightweighting, as the practice is known, but the effort is gaining urgency with the adoption of tougher fuel efficiency standards. To meet the U.S. government's goal of nearly doubling average fuel economy to 45 mpg by 2025, cars need to lose some serious pounds.

Like a Formula One race car stuck in a traffic jam, HPC hardware performance is frequently hampered by HPC software. This is because some of the most widely used application codes have not been updated for years, if ever, leaving them unable to leverage advances in parallel systems. As hardware power moves toward exascale, the imbalance between hardware and software will only get worse. The problem of updating essential scientific ...
