Super-size Mars rover blasts off

NASA’s Mars Science Laboratory (MSL) Curiosity rover lifts off from Launch Complex 41 at Cape Canaveral.

Surrounded by 50 American and French members of his team, Los Alamos National Laboratory's Roger Wiens, a planetary scientist in charge of Curiosity's laser blaster, called ChemCam, shouted, "Go, Go, Go!" as the rocket soared into a cloudy sky.

The 1-ton Curiosity — as large as a car — is a mobile, nuclear-powered laboratory holding 10 science instruments that will sample Martian soil and rocks, and analyze them right on the spot. There’s a drill as well as the laser-zapping device. (Full Story)


The most capable robot geologist ever built now heads to Mars

From a distance of nearly 25 feet, the ChemCam laser zaps material from the surface of a rock, dusting it off and ablating weatherized surfaces, creating a plasma that can be analyzed using the instrument’s telescope. For just five nanoseconds, the laser directs the energy of a million light bulbs into the area the size of a pinhead, said Roger Wiens, the instrument’s principal investigator, based at Los Alamos National Laboratory.

“ChemCam is supposed to be a workhorse for the rover in identifying unique samples for the other instruments to spend more time on,” he said. “The ability to reach out and touch the rock from almost 25 feet away is a real advantage.” (Full Story)


From New Mexico to Mars

The ChemCam laser, developed by researchers from Los Alamos National Laboratory and put into use by scientists at the University of New Mexico, is one of several connections between the car-size rover named Curiosity and the Land of Enchantment.

The ChemCam laser will maximize the efficiency of the other instruments by working like a long-range tentacle to study the chemistry of surrounding areas and help the scientists determine where to send the slow-moving rover, traveling at a top speed of 10 feet per minute, said Los Alamos scientist Roger Wiens, ChemCam’s principal investigator.

Sustainability has not only become a science in the past 25 years, but it is one that continues to be fast-growing, according to new research from Los Alamos National Laboratory and Indiana University.

The findings, recently published in the Proceedings of the National Academy of Sciences, were assembled from a review of 20,000 academic papers written by 37,000 distinct authors representing 174 countries and over 2,200 cities. Authors of the paper are Los Alamos research scientist Luís M. A. Bettencourt and Jasleen Kaur, a Ph.D. student in Indiana University. (Full Story)

McMillan was so confident in the upgrades that he remarked “I must stress that PF-4 even without its recent upgrades is among the most robust structures in the region if not the state. In the event of a major earthquake, I believe I would rather be in PF-4 than in my own home. (Full Story)

Fusion energy is the future; but the future might be quite a long ways off


It’s hard not to get excited listening to Wurden explain the process they’re using at Los Alamos called Magnetized Target Fusion. Wurden and his team are working with an Air Force research lab in nearby Albuquerque.


“We built a plasma injector, and they built a can-crusher, and you put the plasma into that aluminum canister, and then you crush the aluminum can, with the huge current produced by the capacitor bank,” Wurden began.


"You put 11 million amps of current, and that produces a big magnetic field on the outside; that crushes the can very smoothly and uniformly (full story)."


Researchers unravel mystery of quantum-dot blinking


Research by Los Alamos scientists developed a novel spectro-electrochemical experiment that allowed them to controllably charge and discharge a single quantum dot while monitoring its blinking behavior. These experiments facilitated the discovery of two distinct blinking mechanisms.


"Our work is an important step in the development of nanostructures with stable, blinking-free properties for applications from light-emitting diodes and single-photon sources to solar cells," said Victor Klimov (full story).

What are you working on today, Roadrunner?


Roadrunner belongs to the Department of Energy via Los Alamos National Lab. That means it often spends its processing time on rather ominous problems like nuclear weapons modeling and simulation to “assure the safety, security, and effectiveness of the U.S. nuclear deterrent.” In other words, Roadrunner’s work is super top-secret classified.


But Roadrunner was willing to tell us--whilst glancing over both shoulders and dropping its voice slightly--that “models and simulations could include hydrodynamic mixing and turbulence of exotic materials under extreme conditions - temperatures at the core of the sun, time scales in the microseconds, and velocities of millions of miles per hour (full story).”


Secret security supercomputer Cielo, what are you working on today?

Maintaining America's nuclear deterrent is a 24x7 job, but Cielo isn't complaining


Installed this year, Cielo is Los Alamos National Labs’ newest nuclear weapons modeling and simulation platform. As such, specifics on what it’s working on at any given time are closely held. Cielo works for three national laboratories: Los Alamos National Laboratory, Sandia National Laboratories, and Lawrence Livermore National Laboratory.


Like its sister system Roadrunner, it performs advanced physics and predictive simulations to assure the safety, security, and effectiveness of the U.S. nuclear deterrent (full story).

Advanced supercomputer models supplant real-world nuclear weapons tests


After live nuclear testing ended in 1992, supercomputers supplanted explosions so scientists could continue studying how they work. The nation’s stockpile stewardship program, run by the NNSA at three national laboratories, checks the nation’s nukes for any problems.


Supercomputers at Los Alamos, Sandia and Lawrence Livermore national labs conduct tests that can in some ways go beyond the detail of any live explosion (full story).


Supercomputers offer tools for nuclear testing — and solving nuclear mysteries

The simulation of the B-83, a device designed and developed by Livermore in the late years of the Cold War, marked the first time such a major fault in a nuclear weapon was detected largely by computer simulation, Goodwin said. “We have a more fundamental understanding of how these weapons work today than we ever imagined when we were blowing them up,” he added (full story).

Scientist: Global warming 'is real'


Los Alamos National Laboratory senior scientist Manvendra Dubey expressed similar sentiments Tuesday. "The uncertainties are big enough that I don't think we should be talking catastrophe," said Dubey, a co-chairman of this week’s Global and Regional Climate Change conference in Santa Fe (full story).

LANL wins grant for antibody research


From the ABQ Journal - Researchers at Los Alamos National Laboratory will be getting a financial boost as they work to unravel the secrets of how many human genes function. The lab’s bioscience division has been awarded a grant worth more than $4 million from the NIH for the Antibody Library Project.


One way to expose a gene’s function is to take the protein it produces and generate specific antibodies. That’s usually done by vaccinating mice or rabbits (full story).


With improved cybersecurity, Los Alamos moves to cloud, wireless


The Energy Department's Los Alamos National Laboratory has done a yeoman's job in fixing its cybersecurity problems from a decade ago, and now is moving into the cloud and going wireless.

LANL wins cyber security award

The SANS Institute announced Monday that Los Alamos National Laboratory has won the 2011 U.S. National Cybersecurity Innovation Award for their innovative use of vShield and other defense tools that represent a breakthrough model for securing virtual computing and private cloud deployments.
