here's an old saying that if you don't like the weather in New Mexico, wait five minutes. Maybe it should be amended to 10,000 years, according to new research.

In a letter published recently in the journal Nature, Los Alamos National Laboratory researchers and an international team of scientists report that the Southwest region of the United States undergoes "megadroughts"—warmer, more arid periods lasting hundreds of years or longer. (

os Alamos National Laboratory, New Mexico: In 1943, the U.S. established a secre
t laboratory in northern New Mexico with the goal of producing an atomic weapon to end World War II. Just two years later, researchers actually did it.

The making of the atomic bomb changed the course of the war and history; Los Alamos National Laboratory (LANL) changed, too. Today LANL also pursues bioscience, chemistry and environmental science, but maintaining nuclear security is still the lab's chief focus. (

ight now we don't know enough to predict the dynamics of the ice sheets," said ORNL scientist Kate Evans, who leads the SEACISM project. Included in the team are other scientists from Los Alamos National Laboratory, Sandia National Laboratories, and academia. (

e are very fortunate to have caught this star in its early rapid cooling epoch. It has been known for sometime that the neutrino production rates are sensitive to the existence of neutron superfluidity inside the neutron star," says astrophysicist Sanjay Reddy of the Energy Department's Los Alamos National Lab, commenting on the study.

Intel team steps into the light

For a brief moment last week, the Department of Energy pulled back the curtain – ever so slightly – on a clandestine team that’s used to operating under the radar inside Los Alamos National Laboratory and across the globe. (Full Story)
