LANL offers tour of once-secret underground nuke vault
A tunnel and vault dug into a canyon wall in Northern New Mexico that for decades provided the federal government with a secret and secure place to store nuclear material and conduct research during the Cold War this week became a tour stop.
Los Alamos National Laboratory says the top-secret facility known as the “tunnel vault” has been declassified and is being shown on lab tours for the news media and for families of laboratory workers. Thetours are part of the lab’s celebration of its 70th anniversary. (full story)
Top-secret Los Alamos tunnel declassified
A secret tunnel recently revealed underneath Los Alamos has an important national security mission. Built into the side of the mountain, almost 250 feet deep into the rock, are five vaults of historical significance.
The heavily guarded chamber was the first place the U.S. stored nuclear waste materials during the Cold War. "It's weapons-grade nuclear material," Los Alamos National Lab buildings historian Ellen McGhee said. "(It's) definitely secure, very safe and very stable down here." (full story)

How Earth Accelerates Electrons to 99.9 Percent of Light Speed
As the Sun's churning surface letsloose a belch of white-hot flame, it sends out a storm of radiation that washes over the solar system. Luckily for us, Earth's magnetic field shields us from most of these deadly rays. But overhead, something strange and lethal is happening when the solar wind bombards the Earth. A band of radioactive particles circling the planet, called the outer Van Allen belt, starts to charge up like a rail gun. It whips electrons along on its circular racetrack at a breakneck pace—near light speed. The powerful band ebbs and flows with solar radiation, but until today, nobody could be sure how it was creating such swift and energetic particles.
"This is like watching a natural particle accelerator in space," says Geoffrey Reeves, a magnetic field researcher at Los Alamos National Laboratory. (full story)

Van Allen probes pinpoint driver of speeding electrons
Researchers believe they have solved a lingering mystery about how electrons within Earth’s radiation belt can suddenly become energetic enough to kill orbiting satellites. Thanks to data gathered from an intrepid pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, scientists have identified an internal electron accelerator operating within the belts.
“For years we thought the Van Allen belts were pretty well behaved and changed slowly,” said Geoffrey Reeves of Los Alamos National Laboratory’s Intelligence and Space Research Division. “With more measurements, however, we realized how quickly and unpredictably the radiation belts change, and now we have real evidence that the changes originate from within the belts themselves.” (full story)

International Team to Study Demand Response Impacts at New Mexico Utility
Toshiba and Landis+Gyr have teamed up with Japan's New Energy and Industrial Technology Development Organization (NEDO), the University of Kyoto, and Los Alamos County to study demand response pricing programs. Utilizing smart meters and customer volunteers, the partners will study how consumers respond to variable pricing per kilowatt hour and how this impacts their electric demand during the summer months. The research will begin in late July and run through September.
The demand response pricing research is a component of the U.S.-Japan Demonstration Smart Grid Project in Los Alamos. Constructed for a consortium of partners representing NEDO, Los Alamos County, and Los Alamos National Laboratory, the smart grid test bed demonstrates high penetration of renewable energy on an electric grid to meet a residential community’s needs. This includes understanding what influences customers to reduce electric consumption during peak-times when electricity is more expensive and not always available from renewable resources.

National labs studying hurricane season to identify vulnerabilities
As hurricane season in the U.S. builds, typically peaking between August and September, a research and analysis project jointly-housed by Sandia National Laboratories and Los Alamos National Laboratory is seeking to minimize the damage and maximize readiness.
The National Infrastructure Simulation and Analysis Center, operated by the Department of Homeland Security, studies how hurricanes and other disasters disrupt critical infrastructure such as roads, electricity and water systems. NISAC conducts annual analyses of probable impacts on the Gulf Coast and East Coast. Then, when hurricane threats become imminent, it provides analysis used in crisis response.
Researchers Shed New Light On Supraglacial Lake Drainage

Supraglacial lakes -- bodies of water that collect on the surface of the Greenland ice sheet -- lubricate the bottom of the sheet when they drain, causing it to flow faster. Differences in how the lakes drain can impact glacial movement's speed and direction, researchers from The City College of New York (CCNY), University of Cambridge and Los Alamos National Laboratory report in Environmental Research Letters.

Higher-strength, lighter-weight steels could be coming to a car near you in the near future as part of a U.S. Department of Energy advanced manufacturing initiative. Los Alamos National Laboratory and Colorado School of Mines (CSM) researchers are lending their expertise to a three-year, $1.2 million project to develop a new class of advanced steels for the automotive industry, materials that will be produced using cleaner manufacturing methods and eliminating the traditional heat-treatment and associated costs and hazards of the process.
Are Neutrinos Their Own Antiparticles?

A long-standing controversy among particle physicists looks to be settled—in the less exciting way—thanks to new data from an ultrasensitive particle detector deep underground. Physicists operating the GERmanium Detector Array (GERDA) 1400 meters down in Italy's Gran Sasso National Laboratory say that they see no signs of a hypothesized type of nuclear decay called neutrinoless double-beta decay that, were it conclusively observed, would almost certainly merit a Nobel Prize…
…The latest results are "very exciting," says Steven Elliott, a neutrino physicist at the Los Alamos National Laboratory in New Mexico, but they may not quite provide the final word on the matter. "The data indicate that the past claim is very unlikely to be correct," he says. "But there might still be some wiggle room due to the low statistics involved."
Enabling time travel for the scholarly web

An international team of information scientists has begun a two-year study to investigate how web links in scientific and other academic articles fail to lead to the resources being referenced.
This is the focus of the Hiberlink project in which the team from Los Alamos National Laboratory and the University of Edinburgh will assess the extent of “reference rot” using a vast corpus of online scholarly work. It is funded by a grant of $500,000 (£310,000) from the US-based Andrew W. Mellon Foundation, coordinated by EDINA, the designated online services center at the University of Edinburg, which serves the needs of universities and colleges across the UK.

The government of India honored former Los Alamos scientist and Laboratory Fellow Mudundi Raju with a Padma Shri award this year for his distinguished service in science and engineering, providing cancer radiation treatment to the poor of rural India.
“The aim of science is to improve the human condition,” said Nobel Laureate Ilya Prigogine, and Raju has taken this statement to heart. Raju works “with a hope to build a small bridge between rapid developments in medical advances and the life of a common man,” he said, and he is an internationally known scientist in the field of radiation treatments for cancer. He retired from the Laboratory in 1994 to devote himself to providing appropriate cancer radiation treatment to residents of rural India.
