Without any way to see into the blowout preventer, engineers had essentially been operating blind, using the rate of oil flow, for example, to deduce the conditions inside. Help came from Scott Watson, an expert in gamma ray imaging at Los Alamos National Laboratory. Gamma rays, a form of electromagnetic radiation similar to X-rays but higher in energy, might at least penetrate a few inches into the blowout preventer’s thick steel walls.

1998 by the Liquid Scintillator Neutrino Detector at LANL’s LANSCE facility was the first evidence for neu- trino mass. LANL photo.

The MiniBooNE results in particular, however, could come as a delayed vindication for LSND, an anti-neutrino experiment at Los Alamos National Laboratory that in the mid-1990s found a strange anomaly. In that experiment, a type of neutrino appeared at a level that suggested the neutrino family as whole might have to grow to include "sterile neutrinos" -- which would have been a radical new member of the particle zoo, beyond physicists' Standard Model.

An unending mission to contain the stuff of nuclear nightmares

T
he task at the core of nonproliferation efforts remains what it has been for decades: keeping track of nuclear materials and sites to ensure that countries do not make bombs, either in secret or under the pretext of developing nuclear power. It's a daunting scientific and technological challenge.


Since the 1960s, Los Alamos National Laboratory has spearheaded the development of safeguards aimed at preventing another Hiroshima. "It is an enduring mission that has become increasingly important," says William Rees, principal associate director for global security at LANL. "With commercial reactors making a comeback, it's vital that we have foolproof systems in place to insure that the nuclear materials don't fall into the wrong hands." (

LANL and nation need new research facility

In the last month, we have seen dramatic steps toward the emergence of a national consensus on our nation's nuclear-security strategy and the investments needed to support it. That is good for our nation, and for New Mexico.


Los Alamos has a proud history of working on both of these issues. Today, we are home to the nation's only plutonium-processing capability. Unfortunately, the facilities where our scientists, researchers and engineers conduct this critical work date as far back as the Manhattan Project, and the signs of age and decay are becoming more apparent every day.

Tauscher: Quick U.S. Senate Nod for START Unlikely

The administration of U.S. President Barack Obama would like the new nuclear arms reduction treaty to be ratified by the Senate this summer, but a senior State Department official conceded June 9 that seems increasingly unlikely.


Rounding up the 60 votes needed to pass anything has proven extremely difficult in the polarized Senate. And the treaty needs 67 votes for ratification, said Ellen Tauscher, undersecretary of state for arms control and international security.

In remarks to a gathering of scientists from three U.S. nuclear laboratories, she touted progress that Obama's administration has made on nuclear matters so far this year: the START treaty signed by the United States and Russia in April; release of a new nuclear posture review that emphasizes reducing the number of nuclear weapons; and a nuclear summit in which 47 nations agreed to keep nuclear weapons out of the hands of terrorists. "It has been quite a nuclear spring," Tauscher said, but "we may run out of days for a summer ratification." (Full Story)

Model suggests slick could zoom up East Coast

New supercomputer studies suggest it is "very likely" ocean currents will carry oil from the Deepwater Horizon spill in the Gulf of Mexico around the tip of Florida and thousands of miles up the U.S. East Coast this summer, researchers announced Thursday. "It is truly a simulation, not a prediction," said Terry Wallace, principal associate director for science, technology and engineering at the Los Alamos National Laboratory in New Mexico, which collaborated on the project. "But it shows that when you inject something into the Gulf, it is likely to have much larger consequences." (full story)

Oil could reach Atlantic coasts
F
or weeks there have been discussions about the potential for the spreading Gulf of Mexico oil slick to slip around Florida and flow up the East Coast. Now a suite of simulations, run by an international team of ocean and climate scientists, including Mat Maltrud at Los Alamos National Laboratory, shows this is a likely outcome should the flow remain unabated this summer.


The researchers stress there are caveats and uncertainties, most notably related to the state of the gulf’s highly variable loop current in coming weeks. (The Department of Energy put out its own fact sheet stressing that the simulations are highly uncertain.) (full story)

Also in The New York Times:

Nuclear option on Gulf oil spill? No way, U.S. says

Stephanie Mueller, a spokeswoman for the Energy Department, said that neither Energy Secretary Steven Chu nor anyone else was thinking about a nuclear blast under the gulf. The nuclear option was not — and never had been — on the table, federal officials said. Along with the kibbitzers, the government has also brought in experts from around the world - including scores of scientists from the Los Alamos National Laboratory and other government labs - to assist in the effort to cap the well.

LANL works on oil computer simulations
Researchers say spill could spread across Atlantic Ocean within months

Oil from the gushing Deep Horizon well in the Gulf of Mexico could travel around Florida and up the U.S. eastern seaboard, spreading across the Atlantic within months, according to simulations by scientists from Los Alamos National Laboratory and the National Center for Atmospheric Research.

The team's maps, generated this week using the state of New Mexico's Encanto supercomputer, show the possibility of oil getting caught up in a current that swirls around the Gulf of Mexico, then moving rapidly through the gap between Florida and Cuba and into the Atlantic.

The simulations show oil hugging the East Coast as far north as North Carolina before heading out into the Atlantic as it follows the path of the warm Gulf Stream waters.

Scientists cautioned that the simulations are not forecasts, but rather a series of "what if" scenarios useful in exploring the risks as the damaged well continues spewing oil, said Terry Wallace, head of science programs at Los Alamos.

Bomb squads sharpen skills in robot rodeo

Bomb squads from around New Mexico got a chance to sharpen their skills by using a remote-controlled robot — not to blow things up, but to make pancakes. The Robot Rodeo was held last week at a tech site at Los Alamos National Laboratory. The three-day event offered hours of hands-on training at the controls of $225,000 robots used for bomb and hazardous waste detection and disposal. (full story)




Wrangling in the robots

Six teams included The Albuquerque Police Department, the Santa Fe Police Department, the New Mexico State Police, the Farmington Police Department, LANL and the New Jersey State Police competed in 10 different events. Other challenges included an obstacle course performed in the dark, using explosive tools and power tools. "The main purpose of the rodeo," said Robert Clark, a LANL hazardous devices technician, "is we come up with scenarios that are a challenge to both robot and to the operator." (full story)
