Designers of high-speed silicon chips have often had to compromise on performance levels for their integrated circuit designs because of physical weaknesses appearing during design verification or
Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond.
Magnetized plasmas occupy a large fraction of our cosmic universe; they exist on our sun, in the earth's magnetosphere, and in astrophysical plasmas.
LOS ALAMOS, New Mexico, October 29, 2009 -- Very tiny wires, called nanowires, made from such metals as silver and gold, may play a crucial role as electrical or mechanical switches in the develop
Lack of health insurance might have led or contributed to nearly 17,000 deaths among hospitalized children in the United States in the span of less than two decades, according to research led by th
LOS ALAMOS, New Mexico, October 26, 2009 -- Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physic
After over a month of research and exploration of our topic, we have broke ground on our simulation.
Up to this point we have:

Whiter paper and better color reproduction are examples of important competitive advantages on an international market. But how white is a paper? And why do vacation photos turn out so dark if you don't buy expensive photo paper?
(PHILADELPHIA) Migraine sufferers, beware. You may be more prone to an alcohol-induced headache after a night of drinking, according to researchers from the Jefferson Headache Center. The research will be presented at Neuroscience 2009, the Annual Meeting of the Society for Neuroscience, in Chicago.
Recently, I have been on a conference of young scientists in Warsaw. These were great three days of meeting people, eating, drinking, sightseeing, and, occasionally, watching some presentations. I didn't prepare anything myself, but it was still a good opportunity to see what other PhD students work on, and how they handle all the difficulties caused by the imperfect system of higher education in Poland (mainly related to money). One of the precious observations I have made during the conference is that engineers are not as fond of the finite element method as I had imagined. This is a great news for me because I want to put a lot of effort to improve the FEM by making it easier to use, and, this way, available for more people. Let me share with you some of my thoughts.
OAK RIDGE, Tenn., Oct. 9, 2009 -- For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming.
The National Institute for Computational Sciences' (NICS's) Cray XT5 supercomputer -- Kraken -- has been upgraded to become the first academic system to surpass a thousand trillion calculations a second, or one petaflop, a landmark achievement that will greatly accelerate science and place Kraken among the top five computers in the world.
Some stars are lonely behemoths, with no surrounding planets or asteroids, while others sport a skirt of attendant planetary bodies. New research published this week in The Astrophysical Journal Letters explains why the composition of the stars often indicates whether their light shines into deep space, or whether a small fraction shines onto orbiting planets.
ST. PAUL, Minn. -- Drivers with mild to moderate Parkinson's disease may be at higher risk of crashes on foggy days and other times of low visibility. The research, involving a driving simulation test, is published in the October 6, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.
Summary: A new analysis of climate risk, published by researchers at MIT and elsewhere, shows that even moderate carbon-reduction policies now can substantially lower the risk of future climate change.
