Metamaterials provide active control of slow-light devices

February 13, 2013 10:49 am | News | Comments

Wireless communications and optical computing could soon get a significant boost in speed, thanks to “slow light” and specialized metamaterials through which it travels. Researchers have made the first demonstration of rapidly switching on and off “slow light” in specially designed materials at room temperature. This work opens the possibility to design novel, chip-scale, ultrafast devices for applications in terahertz wireless communications and all-optical computing.

DOE, NASA demonstrate simple, robust fission reactor

November 27, 2012 11:18 am | News | Comments

A team of researchers have built a new type of nuclear reactor that is reliable enough to be used on space flights. The prototype, which has been used to generate 24 W of electricity, relies on heat pipe technology developed at Los Alamos National Laboratory in 1983. The fluid-based cooling system requires no moving parts and the reactor itself is based on a simply closed-loop Stirling engine.

Manhattan Project scientist Cowan dies at 92

April 23, 2012 8:29 am | by Susan Montoya Bryan, Associated Press | News | Comments

One of the few people to know the various components of the first atomic bombs, George Cowan would become one of the leading nuclear researchers in the country and a fixture at Los Alamos National Laboratory for nearly 40 years. Still working with nonprofit science institute he helped found, he died Friday as the result of a fall at his home.

Cyber security exercise puts laboratories to the test

April 13, 2012 4:40 am | News | Comments

Recently, Los Alamos National Laboratory hosted an information security exercise dubbed "Eventide" that put more than 100 participants from around the country into a maelstrom of sensitive data leaks and cracked network security. It’s hoped such trials by fire prepare the Department of Energy’s facilities to cope with eventual compromises of cyber integrity.

Magnetic field researchers achieve hundred-tesla goal

March 23, 2012 8:58 am | News | Comments

During a six-experiment pulse this week, the previous world record for laboratory-produced magnetic fields was broken by Los Alamos National Laboratory researchers. The hundred-tesla field, about 2 million times Earth’s magnetic field was produced with the help of a 1,200-MJ motor generator.

Oxygen detected in atmosphere of Saturn's moon Dione

March 5, 2012 3:40 am | News | Comments

Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. The research was made possible by instruments aboard NASA's Cassini spacecraft, which was launched in 1997.

LEDs go ultraviolet with nanocrystal core

February 27, 2012 3:49 am | News | Comments

A multinational team of scientists has developed a process for creating glass-based, inorganic light-emitting diodes (LEDs) that produce light in the ultraviolet range. If successfully integrated into biomedical devices, these would be the first robust, cheap to produce, and chemically stable LEDs to operate in the medically-useful UV spectrum.
