Signatures of Selection Inscribed on Poplar Genomes
— One aspect of the climate change models researchers have been developing looks at how plant ranges might shift, and how factors such as temperature, water availability, and light levels might come into play. Forests creeping steadily north and becoming established in the thawing Arctic is just one of the predicted effects of rising global temperatures.

Catalytic Gold Nanoclusters Promise Rich Chemical Yields
— Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive.

Long-term success
— In the early 1980s, the Department of Energy’s Oak Ridge National Laboratory was just beginning to explore transfer of technology from the lab to industry. Now it's the norm, and one historical example illustrates the long-term benefits.

Nobel Laureate speaks on antibiotics and drug resistance
— Many antibiotics work by blocking protein production in the ribosomes of bacteria. But irresponsibly or incorrectly using antibiotics can contribute to bacterial immunity to antibiotics. Monday's Eugene P. Wigner Distinguished Lecturer, Dr.

A record-breaking month for ORNL’s Spallation Neutron Source
— The Spallation Neutron Source at the Department of Energy’s Oak Ridge National Laboratory broke records for sustained beam power level as well as for integrated energy and target lifetime in the month of June.

Students Learn to Use Neutrons and X-rays at Oak Ridge and Argonne
— The 16th National School on Neutron and X-ray Scattering, or NXS 2014, at Argonne and Oak Ridge National Laboratories came to an end on June 27. A whirlwind 14-day experience jointly conducted by Oak Ridge and Argonne, NXS immerses graduate students in national user facilities to learn in a hands-on environment how to use neutrons and X-rays in their research.

“Take my word for it"
The late Sen. Howard H. Baker was a friend to the Department of Energy's Oak Ridge National Laboratory, which is in the state he represented in Washington. The Tennessee "favorite son" was invited to present the annual Alvin Weinberg Lecture in June 2000. The following is a story on Sen. Baker's talk.

Understanding heat flows is focus of DOE Early Career Award winner Delaire
— Olivier Delaire, a scientist at the Department of Energy’s Oak Ridge National Laboratory, has won a prestigious Early Career Award from DOE’s Office of Science to study how heat propagates, or moves, through matter at an atomic level.

The Smithsonian and ORNL partner to advance science, education
— The Smithsonian Institution and the Department of Energy’s Oak Ridge National Laboratory have announced a new partnership to support collaborative research programs and science education efforts. This is the first partnership between Oak Ridge National Laboratory and the Smithsonian, which was formalized during the signing of a memorandum of understanding June 12.

More than Just Food for Koalas
— From antiseptic oils to the construction of didgeridoos, the traditional Australian Aboriginal wind instrument, the eucalyptus tree serves myriad purposes, accounting for its status as one of the world’s most widely planted hardwood trees.

More than 400 attend American Conference on Neutron Scattering
— The American Conference on Neutron Scattering returned to Knoxville this week, 12 years after its inaugural meeting there in 2002. Coordinated by the Neutron Scattering Society of America and hosted by Oak Ridge National Laboratory, the four-day conference drew 440 attendees and featured oral and poster presentations from the world’s leading experts in neutron science.

UGA, ORNL research team engineers microbes for the direct conversion of biomass to fuel
— New research from the University of Georgia and the Department of Energy’s Oak Ridge National Laboratory has overcome a major hurdle to cost-effective biofuel production by enabling the direct conversion of switchgrass to fuel.

Neutrons and X-rays Reveal Structure of High-temperature Liquid Metal Oxides
— By levitating a bead of ceramic oxide, heating it with a 400-watt carbon dioxide laser, then shooting the molten material with X-rays and neutrons, scientists with the Department of Energy’s Oak Ridge and Argonne national laboratories have revealed unprecedented detail of the structure of high-temperature liquid oxides.

A tipping point for lignin
— Led by Art Ragauskas, the newly appointed Oak Ridge National Laboratory-University of Tennessee Governor's Chair in Biorefining, a multi-institutional team of researchers offers a new view of an organic polymer often dismissed as a worthless by-product. Their perspective appears in Science magazine as Lignin Valorization: Improving Lignin Processing in the Biorefinery.

New ORNL-GE Appliances project aims to revolutionize residential refrigerators
— Not much has changed in refrigeration technology in the past 100 years, until now. Researchers with Oak Ridge National Laboratory’s Building Technologies Program have partnered with General Electric (GE) Appliances through a cooperative research and development agreement (CRADA) to revolutionize home refrigerators using magnetocaloric cooling.

ORNL Researchers Contribute to Report on Impacts of Climate Change in U.S.
— Scientists at the Climate Change Science Institute (CCSI) at the Department of Energy’s Oak Ridge National Laboratory (ORNL), including Thomas Wilbanks, Steve Fernandez, Peter Thornton, Virginia Dale, and Benjamin Preston, were among the 240 authors who contributed to the Third National Climate Assessment (NCA) report.

Bredesen Center Graduates First Class, Sees Phenomenal Growth
— Two students will be the first to earn a new doctoral degree Thursday from the Energy Science and Engineering program founded by former Gov. Phil Bredesen in partnership with the University of Tennessee, Knoxville, and Oak Ridge National Laboratory.

How to create nanowires only three atoms wide with an electron beam
— Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today’s integrated circuits.
