Small, Laser-Beam Box Detects Clandestine Nuclear Materials
More bad news today for bad guys. The scientific brain trust at the Los Alamos National Laboratory in New Mexico has discovered a powerful new method for detecting clandestine nuclear materials.
In February, an international team of researchers used laser-driven neutrons to confirm the presence and quantity of nuclear material inside of a closed container. The experiment is likely to lead to table-top-sized or truck-mounted neutron generators that could be used to catch nuclear smugglers. (full story)

HPC geeks ponder 100 petafloppers and quantum supercomputers
The next big barrier for supercomputing is punching through 100 petaflops peak performance, which frankly could be done in a heartbeat if someone had a few hundred millions dollars lying around. And now that Google and NASA are monkeying around with a quantum computer, thoughts are turning to how a QC might be deployed to replace some of the work done by traditional supercomputer clusters.
And, as it turns out, the RFP for NERSC-8 will also include a second system called "Trinity" that is expected to be installed at Los Alamos National Laboratory to help manage the US government's stockpile of nuclear weapons. The exact floppage of Trinity has not been divulged, but this is a winner-take-all deal and it looks like Trinity will be about twice the size of NERSC-8. So that should be in the range of 200 petaflops. (full story)
Electric automakers address battery anxiety
Ever wish you had a clone or a replacement to handle those more anxiety-riddled moments in life? The electric car industry is building off that premise by offering replacement batteries to solve the biggest issue car buyers have in considering electric vehicles: range anxiety.
Earlier this month, it was reported that researchers at Los Alamos National Laboratory discovered a way to manufacture low cost electric vehicle batteries, which at upwards of $10,000, are the single largest cost of an electric vehicle. (full story)
Bragging rights: A Gates scholar and kudos from Capitol Hill
In light of 2013 being the 10th anniversary of the state Legislature designating UNM-Taos a branch of the state’s flagship university, we have already seen some events worthy of celebration, or at least a little bragging.
After several years of setting aside funds, resources are being applied to student amenities such as indoor social and study areas, outdoor seating in the Pueblo Hall patio, and what will likely be one of the safest outdoor camera monitoring systems in the county, covering the bulk of the Klauer Campus.
The University of New Mexico-Taos campus is a prime example of the public and private sectors working together to employ cleaner energy. Their campus is home to one of the largest solar arrays in the state — a project that was successful thanks to a partnership with Los Alamos National Labs and Kit Carson Electric Cooperative.

Park Williams, a young bioclimatologist and postdoctoral fellow at Los Alamos National Laboratory, has teamed up with other specialists at the U.S. Geological Survey and the University of Arizona to wring new insight from the data set spanning the years 1000 to 2007. Driving recently into the Jemez Mountains near his office, we pass rust-red pines, dead or dying from drought. Later, kneeling next to a freshly cut stump, he points to a ring near the bark. “That thick ring right there is probably 1998,” he says, a wetter El Niño year. (Full Story)
Quantum cryptography promises un-hackable industrial communications

Our view: Science matters for New Mexico
Senator Martin Heinrich.
In Northern New Mexico, we understand how important federal spending is through Los Alamos National Laboratory. Budget cuts — especially the unwise ones from the automatic spending reductions caused by the so-called sequester — are damaging New Mexico’s economy and our scientific progress.
But it’s not just about economic stability, the spending on science can make a difference to our world — particularly, as Sen. Martin Heinrich pointed out in his first speech last week in the Senate, in developing the United States’ energy independence. (Full Story)

Muon scattering at the Fukushima nuclear reactors
Muon radiograph. From Physics Today.
A team from Los Alamos National Laboratory hopes to hasten the dismantlement and remediation efforts by remotely imaging the damaged reactor cores with atmospheric muons produced by cosmic rays.
The particles' penetrating power would produce an x-ray-like image that includes shadows from the denser regions. But because muons are strongly scattered by uranium and other heavy elements, the researchers plan to use their recently developed method that tracks both incident and transmitted particles using two muon detectors, fore and aft of the building.
