30-Apr-2002
Designing electronic devices using supercomputers A proposed molecular memory cell that would allow laptop computer batteries to last 100 times longer than today’s batteries is being modeled computationally on an IBM supercomputer at ORNL. This machine is also being used to simulate electron transport in carbon nanotubes in contact with other components, for future nanoscale electronic devices. Contact: Billy Stair
11-Feb-2002
International effort to sequence the first tree genome Cottonwoods, hybrid poplars, and aspens could play a role in improving the environment, displacing imported oil and creating domestic jobs, but first scientists from the Department of Energy, Oak Ridge National Laboratory, and around the world must sequence the Populus genome. Contact: Ron Walli
1-Jan-2002
Present at the Creation When they synthesized elements 114 and 116, Russian and Livermore scientists confirmed decades-old predictions of the existence of superheavy elements with comparatively long lifetimes. Contact: Dave Leary
31-Dec-2001
From the stone age to the lego block age of computing The Center for Component Technology for Terascale Simulation Software (CCTTSS), another of ORNL's projects to receive funding from DOE's Scientific Discovery through Advanced Computing (SciDAC) Program, may well revolutionize the way terascale software simulations are developed. Contact: Billy Stair
31-Dec-2001
Computer modeling and homeland security ORNL researchers have developed computer-based products that could provide information to help Americans better protect themselves from natural, accidental, or deliberate threats. Contact: Billy Stair
31-Dec-2001
Car crash simulations may improve vehicle efficiency ORNL researchers are building computer models of vehicles made of aluminum, regular steel, high-strength steel, and carbon-fiber composites. This research could lead to safer, energy-efficient cars. Contact: Billy Stair
31-Dec-2001
Computer modeling aids understanding of plasma physics ORNL fusion researchers are using supercomputers to understand plasma turbulence, design a device that could eliminate plasma disruptions, and find ways to get radio waves to not only heat but also control the plasma to allow sustained energy-producing fusion reactions. Contact: Billy Stair
31-Dec-2001
Chemical experiments and predictions by computer Supercomputers can be used to simulate chemical reactions, saving time and money and increasing safety. Contact: Billy Stair
31-Dec-2001
Retaining and retrieving data more effectively ORNL is a co-developer of and customer for the computer industry’s leading data-storage system in terms of capacity and transfer speed. The ORNL data-storage program also includes the Probe Storage Research Facility. Contact: Billy Stair
31-Dec-2001
Developing computer tools for scientists ORNL researchers and their university and national lab colleagues are developing tools to enable scientists to run simulation codes more efficiently on massively parallel supercomputers and clusters of personal computers. Contact: Billy Stair
31-Dec-2001
The science grid Science grids are being established to connect scientists, instruments, computing, and data. Contact: Billy Stair
12-Nov-2001
IBM and DOE pool supercomputing talents to examine disease At the heart of the agreement is IBM's Blue Gene research project, which combines advanced protein science with IBM's next-generation cellular architecture supercomputer design. Contact: Ron Walli
22-Oct-2001
SciDAC DOE initiative targets heart of fusion machine Fusion energy, evident in the sun and stars, is the ultimate source of power because it provides an environmentally acceptable alternative to energy generated by fossil fuels. To achieve fusion energy requires that the fuel material be heated to hundreds of millions of degrees, much hotter than the sun. Contact: Ron Walli
22-Oct-2001
Cancer-detecting microchip clever technique for detecting proteins by inducing them to stick to and bend a microscopic cantilever—essentially a diving board the size of a hair—is sensitive enough to serve as a diagnostic assay for the protein markers characteristic of prostate cancer, a team of scientists report in the September issue of the journal Nature Biotechnology. Contact: Robert Sanders
15-Oct-2001
Spinach protein could offer new hope for the blind Spinach, touted in the Popeye cartoon for its ability to strengthen the body, may prove even more valuable for restoring vision to people who are legally blind. People who suffer from age-related macular degeneration or retinitis pigmentosa, diseases that are leading causes of blindness worldwide, may find hope in this research. Contact: Ron Walli
1-Oct-2001
Supercomputers look to the stars for answers To people like astrophysicist Tony Mezzacappa at DOE's Oak Ridge National Laboratory, this work is about more than just satisfying their curiosity. The project is aimed at answering some basic questions about the origin of life. Contact: Ron Walli

Mauna Loa CO2 measurements are the longest continuous record in the world The Mauna Loa atmospheric CO2 measurements, which began in 1958, constitute the longest continuous record of atmospheric CO2 concentrations available in the world. The Mauna Loa site is considered one of the most favorable locations for measuring undisturbed air because possible local influences of vegetation or human activities on atmospheric CO2 concentrations are minimal and any influences from volcanic vents may be excluded from the records. Contact: Robert M. Cushman

Keeping trucks and the nation on the road to prosperity The 21st Century Truck Partnership aims to secure the future of the nation's trucking industry by developing technologies to increase safety, fuel economy, performance, and to lower emissions. It combines the resources and capabilities of the Department of Energy, Department of Transportation, Department of Defense, Environmental Protection Agency, and 16 industrial partners. Contact: Ron Walli
19-Jun-2001
