Scientists verify world's largest single crystal piece of gold

By - April 16, 2014 2 Pictures
Scientists at Los Alamos National Laboratory (LANL) in the US have confirmed a 7.68 oz (217.78 g) piece of gold is in fact a singular crystal, increasing its value from around US$10,000 to an estimated $1.5 million. The specimen, the largest single crystal piece of gold in the world, was discovered in Venezuela decades ago, but it is only by using advanced probing instruments that experts can now verify its authenticity.

ATHENA "desktop human" for drug and toxic agent screening gets a liver

By - March 26, 2014 1 Picture
A five-year, US$19 million multi-institutional effort is working on developing a "desktop human" that could reduce the need for animal testing in the development of new drugs. The "homo minitus" is a drug and toxicity analysis system that would comprise four human organ constructs interconnected to mimic the response of human organs. The project has now reported success in the development of its first organ construct, a human liver construct that responds to exposure to a toxic chemical much like a real liver. Read More

LANL pulsed magnet smashes the 100 Tesla magnetic pulse barrier

By - March 26, 2012 5 Pictures
Round performance numbers aren't necessarily important milestones, but they do exude an undeniable aura of accomplishment. This was the case when researchers at Los Alamos National Laboratory (LANL) used their largest pulsed magnet to crack the 100 Tesla mark (roughly 2 million times larger than the Earth's magnetic field) by generating a 100.75 Tesla magnetic pulse without damaging the magnet.

New transparent, light-harvesting material could lead to power generating windows

By - November 3, 2010 3 Pictures
While rooftops are the obvious place to put solar cells to generate clean electricity for the home, we’ve seen a number of technologies aimed at expanding the potential solar collecting area to include windows using transparent solar cells. These include Octillion Corp’s NanoPower Window technology, RSi’s semi-transparent photovoltaic glass windows, and EnSol’s transparent thin film. In this latest development, U.S. scientists have fabricated a new type of self-assembling transparent thin film material that could boost the cost effectiveness and scalability of solar window production.

Self-healing materials could lead to safer nuclear reactors

By - March 30, 2010 1 Picture
One of the key challenges when designing nuclear reactors is finding materials that can withstand the massive temperatures, radiation, physical stress and corrosive conditions of these extreme environments. Exposure to high radiation alone produces significant damage at the nanoscale, so scientists at Los Alamos National Laboratory, New Mexico, have been working on a mechanism that allows nanocrystalline materials to heal themselves after suffering radiation-induced damage. This gives hope for materials that will improve the reliability, safety and lifespan of nuclear energy systems. Read More

World’s faster supercomputer models origins of the unseen universe

By - October 30, 2009 1 Picture
Scientists have for some time postulated that "dark matter" could partially account for evidence of missing mass in the universe, while the hypothetical form of energy known as "dark energy" is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate and accounts for 74 percent of the total mass-energy of the universe according to the standard model of cosmology. To better understand these two mysterious cosmic constituents scientists at the Los Alamos National Laboratory (LANL) are using Roadrunner, the world’s fastest supercomputer, to model one of the largest simulations of the distribution of matter in the universe.
