New CO2 Removal Technique Produces Green Fuel, Offsets Ocean Acidification
2013-05-29 10:31:52

April Flowers for redOrbit.com - Your Universe Online A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists at the Lawrence Livermore National Laboratory (LLNL). The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification. At laboratory scale, the team demonstrated a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral...

Scientists at Lawrence Livermore National Laboratory (LLNL)  and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Methane is a substantial driver of global climate change, contributing 30 percent of current net climate warming. Concern over methane is mounting, due to leaks associated with rapidly expanding unconventional oil and gas extraction, and the potential for large-scale release of...

US Navy Wants Laser Weapon System On Ships By 2014
2013-04-09 11:26:45

Michael Harper for redOrbit.com — Your Universe Online [ Watch the Video: Laser Weapon System On USS Dewey ] The US Navy believes the time to embrace the future is now as it looks to mount a weaponized laser on one of its ships. The laser weapon system, or LaWS, has been in testing for several years and now the pentagon believes it can effectively be used to bring down slow-flying drones and injure nearby ships. The Navy says it plans to have the laser installed by fiscal 2014,...

Roadrunner Supercomputer Decommissioned On Sunday
2013-04-01 04:29:31

redOrbit Staff & Wire Reports - Your Universe Online The first supercomputer to complete one quadrillion calculations per second has been officially decommissioned, going offline Sunday after being operational for the past five years. The computer, which was known as Roadrunner, was built by IBM and went online in 2008. The $120 million Roadrunner quickly became the fastest supercomputer on Earth (a title it held until November 2009). Its success was largely due to technology that...

NRL Nike Laser Focuses On Nuclear Fusion
2013-03-20 15:20:24

U.S. Naval Research Laboratory Researchers at the U.S. Naval Research Laboratory have successfully demonstrated pulse tailoring, producing a time varying focal spot size known as 'focal zooming' on the world's largest operating krypton fluoride (KrF) gas laser. The Nike laser is a two to three kilojoule (kJ) KrF system that incorporates beam smoothing by induced spatial incoherence (ISI) to achieve one percent non-uniformity in single beams and 0.16 percent non-uniformity for 44...

Record Simulations Performed On Lawrence Livermore Supercomputer
2013-03-20 08:30:42

Lawrence Livermore National Laboratory Researchers at Lawrence Livermore National Laboratory have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world. Sequoia, based on IBM BlueGene/Q architecture, is the first machine to exceed one million computational cores. It also is No. 2 on the list of the world's fastest supercomputers, operating at 16.3 petaflops (16.3 quadrillion floating point operations per second). The simulations are...

Human activities are not the primary cause of arsenic found in groundwater in Bangladesh. Instead, a team of researchers from Lawrence Livermore National Laboratory, Barnard College, Columbia University, University of Dhaka, Desert Research Institute and University of Tennessee found that the arsenic in groundwater in the region is part of a natural process that predates any recent human activity, such as intensive pumping. The results appear in the March 4 edition of the Proceedings...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
