Sandia supercomputers offer new explanation of Tunguska disaster

DOE/Sandia National Laboratories
Peer-Reviewed Publication

The stunning amount of forest devastation at Tunguska a century ago in Siberia may have been caused by an asteroid only a fraction as large as those postulated in previously published estimates, Sandia supercomputer simulations suggest. Because there are more smaller asteroids than larger ones, the need to guard against such impacts may be greater than previously thought.

Collaboration yields 'the right glasses' for observing mystery behavior in electrons

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

An international team of researchers has, for the first time, viewed on a nanoscale the formation of mysterious metallic puddles that facilitate the transition of an electrically insulating material into an electrically conducting one.

Did early Southwestern Indians ferment corn and make beer?

DOE/Sandia National Laboratories
Peer-Reviewed Publication

The belief among some archeologists that Europeans introduced alcohol to the Indians of the American Southwest may be faulty. Ancient and modern pot sherds collected by New Mexico state archeologist Glenna Dean, in conjunction with analyses by Sandia National Laboratories researcher Ted Borek, open the possibility that food or beverages made from fermenting corn were consumed by native inhabitants centuries before the Spanish arrived.

Inexpensive 'adaptive optics' achieved by Sandia's optical clamp

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories has received a US patent for a new tool that efficiently but inexpensively uses a single mirror to achieve some of the same effects as adaptive optics, where individually angled mirrors correct distortions in laser beams.

Sandia supports development of US Army's new cannon system

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Researchers at Sandia National Laboratories in California have emerged as key players in a state-of-the-art program for the US Army that focuses on the design and manufacturing of a lightweight, high-caliber, self-propelled cannon system.

A safer food supply -- Sandia and FDA to make it so

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A team from Sandia National Laboratories research team led the effort to computerize a new FDA program so that it will be distributed as widely as possible.The downloadable program, called "CARVER + Shock," provides a series of interactive questions. The program helps companies of any size determine vulnerabilities along their food-processing chain.

Nanoparticles unlock the future of superalloy metals

DOE/Sandia National Laboratories
Peer-Reviewed Publication

As part of Sandia's nanoscale research, a group of experts specializing in inorganic synthesis and characterization, modeling and radiation science have designed a radical system of experiments to study the science of creating metal and alloy nanoparticles.

Extreme environment biology research may help solve lignocellulosic ethanol puzzle

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Beneath a sulfurous cauldron in European seas lies a class of microorganisms known as extremophiles. These organisms and their associated enzymes could somehow unlock the key to a new transportation economy based on a renewable biofuel, lignocellulosic ethanol. That's the concept behind a research program at Sandia National Laboratories.
