The environment has a more formidable opponent than carbon dioxide. Another greenhouse gas, nitrous oxide, is 300 times more potent and also destroys the ozone layer each time it is released into the atmosphere. Luckily, nature has a larger army than previously thought combating this greenhouse gas—according to a study by Frank Loeffler, Governor’s Chair for Microbiology, and his colleagues.
Oak Ridge National Laboratory News
UT’s supercomputer, Beacon, may not be the fastest but it is the greenest. It was listed at the top of the Green500 which ranks the most energy-efficient supercomputers in the world.
An article co-authored by UT’s Joint Institute of Computational Sciences and oak Ridge National Laboratory researchers has earned recognition from IOP Science. The article conveys details of the research team’s investigation of a physics-based method of DNA sequencing, which is intended to read the hereditary traits coded in human DNA.
Jack Dongarra, distinguished professor in the electrical engineering and computer science department, was written about in the Wall Street Journal. Dongarra’s Top500 list which ranks the world’s fastest supercomputers was released this week listing Oak Ridge National Laboratory’s Titan at the top.
It’s official. UT researchers have access to the world’s fastest supercomputer enabling them to tackle the world’s toughest challenges. The “TOP500″ list ranking the world’s fastest supercomputers was released today, listing Oak Ridge National Laboratory’s massive new system, named Titan, as the fastest computer. The list is published twice yearly by a collaboration between Jack Dongarra, distinguished professor in the Department of Electrical Engineering and Computer Science, and colleagues at Lawrence Berkeley National Laboratory and the University of Mannheim.
A team of three professors has combined high-tech experiments with supercomputing to probe the function of critical enzymes called cytochrome P450s. Understanding the various internal motions these enzymes undergo to bind different drugs will aid in the design of medicines.
The U.S. Department of Energy’s Oak Ridge National Laboratory unveiled their new flagship computer, Titan, on Monday. The Department also announced its latest round of Innovative and Novel Computational Impact on Theory and Experiment award recipients. Titan is ten times more powerful than its predecessor, Jaguar, with a theoretical peak performance of twenty petaflops, or 20,000 trillion calculations per second.
Power from nuclear fusion reactors has the promise to be safe, sustainable, and limitless. But science has not been able to bring fusion energy to the commercial energy market. This is partly because the operating limits of the reactor materials are not known. A team of researchers at UT Knoxville and Oak Ridge National Laboratory, in collaboration with seven other institutions, is trying to solve this challenge.
The Knoxville News Sentinel looked at where scientists from Oak Ridge National Laboratory received their doctorates and found a majority of world-renowned scientists studied at the University of Tennessee.
Speculation over the nuclear ambitions of countries like Iran and North Korea and debate over proposed nuclear reactors in the US and abroad make it apparent that the need for nuclear security experts did not end with the Cold War. For this reason, UT Knoxville has launched the UT Institute for Nuclear Security.
