LOS ALAMOS, New Mexico, February 28, 2011 — There’s an old saying that if you don’t like the weather in New Mexico, wait five minutes. Maybe it should be amended to 10,000 years, according to new research.
In a letter published recently in the jo…
HYDROPOWER — Fishy behavior . . .
Proposals to install hydrokinetic turbines — like underwater windmills — in rivers across the U.S. are prompting questions about the environmental impacts of this new hydropower energy source. In response, r…
Oak Ridge National Laboratory researchers Jeremy Busby, De-en Jiang and Sergei Kalinin are among 13 Department of Energy scientists to receive the Presidential Early Career Award for Scientists and Engineers, or PECASE.
The PECASE, one of the nat…
Hoping to track cancer as it spreads cell-by-cell through the body, Lawrence Berkeley National Laboratory researchers have developed a way to shape high-resolution microscopy images into three-dimensional renditions of tissue such as mammary ducts. The result is a microscopic look at the molecular and genetic underpinnings of cancer on a glandular scale. The system, which couples a computer-assisted microscope to powerful visualization programs, stacks two-dimensional microscopy images into a lifelike structure packed with genes, hormone receptors, and proteins.
Molecular wires are seen by scientists as one key to producing ever-smaller and faster electronic circuits and switches, like those used in computers and complex electronic devices. These “nanowires,” so called because they have dimensions on the order of a nanometer (a billionth of a meter), allow high rates of electron transfer and associated low resistance, or impedance to the flow of current. Now, research focused on finding good candidate materials for these wires is giving scientists a better understanding of how they work.
