In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists. To address criticism of the reliability of thermometer records of surface warming, Lawrence Livermore National Laboratory scientists analyzed satellite measurements of the temperature of the lower troposphere and saw a clear signal of human-induced warming of the planet.
American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low. The United States used more fossil fuels in 2010 than in 2009, while renewable electricity remained approximately constant, with an increase in wind power offset by a modest decline in hydroelectricity. There also was a significant increase in biomass consumption, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.
Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate the billowy air masses. But Lawrence Livermore National Laboratory scientists and international collaborators have developed a new tool that will help scientists better represent the clouds observed in the sky in climate models.
Lawrence Livermore National Laboratory (LLNL) issued a call to energy businesses of all sizes for proposals to collaborate with LLNL teams of experts in advancing energy technology through the use of high performance computing (HPC).
An international team has measured, for the first time, the spatial and temporal coherence of a single femtosecond X-ray pulse generated by the first hard X-ray free-electron laser (XFEL), the Linac Coherent Light Source, at the SLAC National Accelerator Laboratory.
Heavy-ion fusion, a special approach to creating fusion for electrical power production, has long been the choice of Lawrence Berkeley National Laboratory accelerator physicists. Now the near prospect of "burn and gain" at the National Ignition Facility, plus a forthcoming National Academies report on inertial confinement fusion energy, have spurred new interest in heavy-ion fusion.
Lawrence Livermore National Laboratory, working with Loyola University, has won a $3.5 million grant from the National Institutes of Health to help develop a new anthrax vaccine. The grant is the first major NIH-funded biodefense grant focused on LLNL's nanolipoprotein technology.
Researchers at Lawrence Livermore National Laboratory recently received $3 million from the National Institutes of Health to acquire a new biomedical accelerator mass spectrometry (bioAMS) instrument. The instrument will provide faster analysis for medical and other biological research.
Picture this: You've brought your sick child to the doctor's office. After checking her pulse and blood pressure, he takes a nasal or throat swab and inserts it into a mysterious black box. Before the doctor finishes his examination, the black box beeps, indicating that the pathogen that's making your child sick has been identified. This scenario is now closer to becoming a reality.
Using acceleration 1 trillion times faster than a jet fighter in a maximum turn, researchers have gained new insight into dynamic compression of aluminum at ultra-high strain rates. Controlled shock compression has been used for decades to examine the behavior of materials under extreme conditions of pressure and temperature.
Lawrence Livermore National Laboratory has received $890,000 from U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy to help accelerate geothermal energy technology. The main project, "Stochastic Joint Inversion for Integrated Data Interpretation in Geothermal Exploration," aims to reduce resource exploration costs by developing a processing technique for a variety of geophysical and geological parameters.
Researchers at Sandia National Laboratories have designed and built a mobile research facility to trace and identify the origin of greenhouse gases. In addition to pinpointing the chemicals' location, the unique mobile facility can help researchers learn whether the gases are biogenic (coming from plant sources) or anthropogenic (coming from man-made sources).
That old moon might not be as antique as we thought, some scientists think. In a new study regarding Apollo 16 moon rocks, they say it's possible that it isn't a day over 4.4 billion years old. But detractors stick to another number.
Designed to help determine the minimum energy needed to start the fusion process at the National Ignition Facility, Serrated Light Illumination for Deflection-Encoded Recording (SLIDER) deflects light beams at a rate of one resolvable spot per picosecond.
Lawrence Livermore National Laboratory, which is pursuing fusion research at its National Ignition Facility, has expanded the scope of its research by singing a memorandum of understanding to engage in joint research and exchange personnel with Spain's Instituto de Fusion Nuclear.
Lawrence Livermore National Laboratory has signed an agreement with the Clean Energy Research Institute in China to conduct joint research and development of clean energy technologies.
In an initiative that aims to boost the nation's economic competitiveness, Lawrence Livermore National Laboratory announced the opening of the High Performance Computing Innovation Center (HPCIC). The innovation center will facilitate national lab/industry collaboration, applying high performance computing to product design, development, and manufacturing; data management; and the operation of complex energy and communication systems.
An organic compound that smells like cabbage and has been called the "smell of the sea" could be more sensitive to global climate change than commonly believed. In a recent report, a Livermore researcher, along with colleagues from Los Alamos and Oak Ridge national laboratories and the New Mexico Institute of Mining and Technology, found through computer modeling that dimethyl sulfide (DMS) will increase significantly in certain parts of the ocean and decrease in others if the world continues with a business-as-usual fossil fuel dependency.
Livermore Lab has signed a memorandum of understanding with SWAY, a renewable energy company, that has developed floating towers for wind turbines located in deep water. Though California has not yet approved offshore wind turbines, SWAY will launch a 1/5 scale prototype of the technology off the coast of Norway on June 10 to demonstrate how the system could work in the Pacific Ocean.
Element numbers 114 and 116 have been officially recognized by an international committee of chemists and physicists. Going by the temporary monikers of ununquadium and ununhexium, the new elements were created in an accelerator by a team of Russian and American scientists. They hurtled calcium together with curium (forming Element 116) and plutonium (forming Element 114).
By combining high pressure with high temperature, Livermore researchers have created a nanocyrstalline diamond aerogel that could improve the optics for something as big as a telescope or as small as the lenses in eyeglasses.
Researchers at Lawrence Livermore National Laboratory (LLNL) have found that soldiers using military helmets one size larger and with thicker pads could reduce the severity of traumatic brain injury (TBI) from blunt and ballistic impacts.
A new computational study published in the Proceedings of the National Academy of Sciences reveals how hydrocarbons may be formed from methane in deep Earth at extreme pressures and temperatures.
Unlike many conventional chemical detectors that require an external power source, Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires, rather than traditional batteries.
When a NASA spacecraft goes into orbit around Mercury Thursday evening (March 17, 2011), a team of Lawrence Livermore National Laboratory researchers will be paying close attention. The researchers developed a germanium-based gamma ray spectrometer that has been winging its way aboard the Mercury MESSENGER for the past six-and-half years.
