Carbon nanostructures -- elixir or poison?

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A Los Alamos National Laboratory toxicologist and a multidisciplinary team of researchers have documented potential cellular damage from "fullerenes" -- soccer-ball-shaped, cage-like molecules composed of 60 carbon atoms. The team also noted that this particular type of damage might hold hope for treatment of Parkinson's disease, Alzheimer's disease or even cancer.

Safer nuclear reactors could result from Los Alamos research

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Self-repairing materials within nuclear reactors may one day become a reality as a result of research by Los Alamos National Laboratory scientists. In a paper appearing today in the journal Science, Los Alamos researchers report a surprising mechanism that allows nanocrystalline materials to heal themselves after suffering radiation-induced damage.

HIV vaccine strategy expands immune responses

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Two teams of researchers -- including Los Alamos National Laboratory theoretical biologists Bette Korber, Will Fischer, Sydeaka Watson, and James Szinger -- have announced an HIV vaccination strategy that has been shown to expand the breadth and depth of immune responses in rhesus monkeys. Rhesus monkeys provide the best animal model currently available for testing HIV vaccines.

Julia Phillips to speak on solid-state lighting's contributions to national energy efficiency

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Solid-state lighting and its potential as a near-term generator of energy efficiencies will be the topic of a presentation by Julia Phillips, director of the Physical, Chemical, and Nano Sciences Center at Sandia National Laboratories, at the 2010 AAAS annual meeting.

Fueling the future with fish tank residue: Sandia scientist discusses use of algae as a biofuel

DOE/Sandia National Laboratories
Peer-Reviewed Publication

As Americans demand new and cleaner ways to meet the country's energy needs, researchers are turning to algae as a promising new fuel source. The approach has the potential to significantly reduce the nation's reliance on imported oil while contributing to rural economic development and lowering greenhouse emissions.

Supercomputer flexibility increased by virtualized operating system

DOE/Sandia National Laboratories
Business Announcement

New work on Sandia National Laboratories' Red Storm supercomputer -- the 17th fastest in the world -- is helping to make supercomputers more accessible, in effect removing them from the solitary confinement of their specialized operating systems.

Glitter-sized solar photovoltaics produce competitive results

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used.

Sandia's Battery Abuse Testing Laboratory awarded $4.2 million in stimulus funds

DOE/Sandia National Laboratories
Grant and Award Announcement

Sandia National Laboratories will use $4.2 million in American Recovery and Reinvestment Act funds to modify and enhance its existing Battery Abuse Testing Laboratory, with the goal of developing low-cost batteries for electric and plug-in hybrid electric vehicles.

Stopping MRSA before it becomes dangerous is possible, Sandia/UNM researchers find

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Most scientists believe that staph infections are caused by many bacterial cells that signal each other to emit toxins. The signaling process is called quorum sensing because many bacteria must be present to start the process. But the Jeff Brinker research group has determined that the very first stage of staph infection, when bacteria switch from a harmless to a virulent form, occurs in a single cell and that this individual process can be stopped by the application of a simple protein.
