Optimize carbon dioxide sequestration, enhance oil recovery

Los Alamos researchers and collaborators from the University of Utah have created a generic integrated framework simulation to optimize carbon dioxide (CO2) sequestration and enhance oil recovery (CO2-EOR) based on known parameter distributions for a depleted oil reservoir in Texas.

CO2-EOR is a technique in use for over 40 years to produce oil from depleted reservoirs by injecting CO2 along with water. Because a large portion of the injected CO2 remains in place, CO2-EOR is an option for permanently sequestering CO2. (Full Story)

Superconducting materials exhibit unexpected behaviors when subjected to magnetic fields or high pressures according to two studies at Los Alamos National Laboratory with collaborators in Switzerland and South Korea.

Superconductivity in Cerium-Colbalt-Indium5, discovered nearly a decade ago at Los Alamos, may be the Rosetta Stone that many of us have been looking for" says Joe Thompson, a collaborator in both studies. (Full Story)

New coalition defends U.S. nuclear complex

The Strategic Deterrent Coalition’s inception comes at a time of tight federal budgets that threaten to crimp nuclear weapons spending at Los Alamos and Sandia national laboratories in New Mexico.

The Strategic Deterrent Coalition bills itself as nonprofit and non-partisan and funded by donations. Nearly two dozen politicians and ex-military and nuclear weapons officials, including Linton Brooks, a former director of the National Nuclear Security Administration, and former U.S. Sen. Pete Domenici of New Mexico, have endorsed the organization. (Full Story)

Researchers make predictions on how climate shifts will affect the planet

The amount of moisture in the air during the warm months of the year and rain and snowfall in the winter accounts for 82 percent of droughts, according to a tree-ring study by Park Williams, with Los Alamos National Laboratory in New Mexico and presented at a recent conference in Flagstaff. The researchers studied a massive set of tree ring records that showed rainfall patterns for the past 1,000 years. (Full Story)

NASA’s Swift catches X-ray action at Milky Way’s center

Recent observations by NASA’s Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy. The Swift collaboration includes NASA Goddard, Los Alamos National Laboratory and others.

Scientists presented their research into images captured by Swift, explaining how these images will help decipher the physical nature of X-ray flares and enabled their discovery of a rare subclass of neutron star. (Full Story)

Tuition aid for northern students

Northern New Mexico students aiming to pursue four-year college degrees are eligible for tuition help ranging from $1,000 to $30,000 from the Los Alamos Employees’ Scholarship Fund.

The fund, which has awarded $3.7 million since 1998, is administered by the Los Alamos National Laboratory Foundation. (Full Story)
