Climate and energy scientists at Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise.

“For the first time, we were able to apply data at a high enough resolution to be relevant,” said ORNL’s Melissa Allen, co-author of “Impacts of Climate Change on Sub-regional Electricity Demand and Distribution in the Southern United States,” published in Nature Energy.

Allen and her team developed new algorithms that combine ORNL’s unique infrastructure and population datasets with high-resolution climate simulations run on the lab’s Titan supercomputer. The integrated approach identifies substations at the neighborhood level and determines their ability to handle additional demand based on predicted changes in climate and population.

The new, high-resolution capability can explore the interconnections in complex systems such as critical infrastructure and weather and determine potential pathways to adapt to future global change, a press release said. [Read more…]

The American Physical Society on Monday honored the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory as an APS Historic Physics Site.

It’s the first designated APS Historic Physics Site in Tennessee. The APS is one of the world’s top professional societies for scientists.

APS President-elect Laura Greene presented a plaque marking the historical designation of the now-decommissioned physics research facility to kick off the Nuclear Structure 2016 conference and Neutrinos in Nuclear Physics workshop being held this week in Knoxville. ORNL Deputy for Science and Technology Thomas Zacharia accepted the plaque for ORNL.

ORNL is a U.S. Department of Energy laboratory.

“In naming the Holifield Radioactive Ion Beam Facility as a Historic Physics Site, the American Physical Society took into consideration the half century of nuclear and atomic physics research performed there, as well as the scores of scientists who performed experiments with its unique capabilities,” Greene said. “The Holifield Facility has indeed been an important contributor to the physical sciences history.” [Read more…]

Environmental scientists can more efficiently detect genes required to convert mercury in the environment into more toxic methylmercury with molecular probes developed by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory. The research could help the cleanup work at the Y-12 National Security Complex.

“We now have a quick and easy-to-use tool that we can employ in any environment to test for the presence of microorganisms capable of methylating mercury and determine how abundant they are,” said ORNL’s Geoff Christensen, a post-doc and lead author of a paper published in Applied and Environmental Microbiology.

In 2013, ORNL researchers reported in Science on the discovery of two genes known to transform inorganic mercury into its highly toxic organic form. Development of the newly validated probes further advances research to protect human health, a press release said.

For this study, researchers tested the probes against 31 strains of microorganisms for which they know the ones that produce methylmercury and scored a 94 percent confirmation rate, the press release said. This validation procedure is critical to the next step of moving the probes into the field to help determine the amount of methylmercury likely to be generated in any given environment. [Read more…]

The U.S. Department of Energy announced Friday that it is investing $19 million to improve the efficiency of the nation’s homes, offices, schools, hospitals, restaurants, and stores. The projects will develop advanced building technologies that will help American consumers and businesses save money on their utility bills, reduce greenhouse gas emissions, and create jobs, a press release said.

Oak Ridge National Laboratory received four of the 18 awards.

Buildings are the largest energy consumer in the nation—accounting for more than 40 percent of the nation’s total energy demand and greenhouse emissions, and resulting in an annual energy bill totaling $430 billion, the press release said. On average, nearly a third of this energy is wasted. It’s estimated that if the U.S. reduced energy use in buildings by 20 percent, the nation could save nearly $80 billion annually on energy bills.

The 18 innovative projects announced Friday will develop sensors and energy modeling tools to make buildings smarter, reduce refrigerant leaks and improve the efficiency of heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems, and produce a low-impact, gas-powered heat pump that can operate efficiently in colder climates. The projects will also support renewable energy market penetration through energy storage, pinpoint air leaks and reduce energy losses through the building envelope, and cut electricity use by transmitting sunlight to building interiors, the press release said.

Oak Ridge National Laboratory and its Titan supercomputer are helping the U.S. Department of Energy fight cancer through a national initiative called Cancer Moonshot.

U.S. Energy Secretary Ernest Moniz wrote about the use of DOE supercomputers to fight cancer in an article posted on Medium.com on Friday.

“Cancer is a worldwide public health problem, and the second-leading cause of death in the United States,” Moniz said. “Although cancer mortality has declined in recent years, there is no one who hasn’t been touched by cancer personally. So when President Obama announced that Vice President Biden would lead the Cancer Moonshot during his State of the Union address and asked for all hands on deck, I was eager to join the Cancer Moonshot Task Force and lend the support of the Department of Energy and our 17 national laboratories.”

As part of the initiative, the U.S. Department of Energy is launching three pilot projects in partnership with the National Cancer Institute, ORNL spokesperson Morgan McCorkle said. The projects will bring together nearly 100 cancer researchers, care providers, computer scientists, and engineers to apply the nation’s most advanced supercomputing capabilities to analyze data from preclinical models in cancer, cancer surveillance data, and molecular interaction data for RAS genes, McCorkle said. (About one third of all human cancers, including a high percentage of pancreatic, lung, and colorectal cancers, are driven by mutations in RAS genes, according to the National Cancer Institute.)

A new 200-petaflop supercomputer will succeed Titan at Oak Ridge National Laboratory, and it could be available to scientists and researchers in 2018, a spokesperson said this week.

The new IBM supercomputer, named Summit, could about double the computing power of what is now the world’s fastest machine, a Chinese system named Sunway TaihuLight, according to a seminannual list of the world’s top supercomputers released in June.

Sunway TaihuLight is capable of 93 petaflops, according to the list, the TOP500 list. A petaflop is one quadrillion calculations per second. That’s 1,000 trillion calculations per second.

Summit, which is expected to start operating at ORNL early in 2018, is one of three supercomputers that the U.S. Department of Energy expects to exceed 100 petaflops at three U.S. Department of Energy laboratories in 2018. The three planned systems are:

  • the 200-petaflop Summit at ORNL, which is expected to be available to users in early 2018;
  • a 150-petaflop machine known as Sierra at Lawrence Livermore National Laboratory near San Francisco in mid-2018; and
  • a 180-petaflop supercomputer called Aurora at Argonne National Laboratory in Chicago in late 2018.

Frank Munger, U.S. Department of Energy reporter for the Knoxville News Sentinel, received a Muddy Boot Award from the East Tennessee Economic Council during a retirement celebration on Wednesday.

Munger is retiring today (June 30) after 35 years covering DOE for the News Sentinel. Many consider him to be the best DOE reporter in the DOE complex. It’s not clear if he will be replaced. Some have said he is irreplaceable.

Among those who praised Munger’s work and “shoe-leather” journalism on Wednesday, even if DOE wasn’t always pleased with his stories, were current and former DOE and contractor officials Gerald Boyd, Sue Cange, Dave Keim, Thom Mason, Billy Stair, and Jim Alexander. They recalled humorous moments; his pocket-sized voice recorder, which he was carrying Wednesday; the occasional arguments; and his ability to translate stories about complex subjects such as the Spallation Neutron Source into language that people without scientific training could understand. They also presented Munger with mementos, including a framed collection of photos from Oak Ridge National Laboratory showing Munger at work over the years, reporting at the lab.

“I can say without reservation that you were always accurate and fair in your reporting—mostly,” said Boyd, a former DOE Oak Ridge Office manager who was unable to attend but delivered his message through a sometimes-humorous letter to Munger. “You always tried to tell all sides of each story, and we all appreciated that even when the story was hard to accept. Your studied approach to reporting on things DOE Oak Ridge always kept the important issues visible and in the forefront, forcing us to have to deal with them. I believe that made us a better operation. In particular, your in-depth articles on various Oak Ridge programs, projects, and activities were excellent tutorials for the general public and helped us explain the value of the Oak Ridge missions. We will miss that.” [Read more…]

A multinational team led by the U.S. Department of Energy’s Oak Ridge National Laboratory Climate Change Science Institute has found the first positive correlation between human activity and enhanced vegetation growth.

The research team, led by Jiafu Mao of the Ecosystem Simulation Science group in the Environmental Sciences Division, used new environmental data and strict statistical methods to discover a significant human-vegetation interaction in the northern extratropical latitudes, the section of the planet spanning 30 to 75 degrees north, roughly between the Tropic of Cancer and the North Frigid Zone above the Arctic Circle.

“This is the first clear evidence of a discernible human fingerprint on physiological vegetation changes at the continental scale,” Mao said. [Read more…]
