Researchers dish the dirt on soil microbes

May 16, 2019- 
Soil microbes are wild, unpampered and uncultured. But to understand their ecology, don't look in laboratory cultures, look in the soil. That’s exactly what Lawrence Livermore National Laboratory (LLNL) and Northern Arizona University (NAU) scientists did. Relationships between microbial genes and performance are often evaluated in the lab in pure cultures, with little validation in nature...

The research appears in the May 13 online edition of the Applied Physics Letters and it is highlighted as a cover and...

Giant lasers crystallize water with shockwaves, revealing the atomic structure of superionic ice

May 8, 2019- 
Scientists from Lawrence Livermore National Laboratory (LLNL) used giant lasers to flash-freeze water into its exotic superionic phase and record X-ray diffraction patterns to identify its atomic structure for the very first time — all in just a few billionths of a second. The findings are reported today in Nature. In 1988, scientists first predicted that water would transition to an exotic...

Human impact on droughts goes back 100 years

May 1, 2019- 
Observations and climate reconstructions using data from tree rings confirm that human activity was affecting the worldwide drought risk as far back as the early 20th century. New research from NASA Goddard Institute for Space Studies (GISS), Lawrence Livermore National Laboratory (LLNL) and Columbia University shows that greenhouse gas emissions in the first half of the century (1900-1949)...

U.S. energy use rises to highest level ever

April 11, 2019- 
Americans used more energy in 2018 than in any other year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Overall total energy consumption rose to 101.2 quadrillion BTU (or "quads"). The prior record, set in 2007, was 101.0 quads. Energy use went up by 3.6 percent from 2017, which also is the largest annual increase since 2010. Each...

Lab scientists use radioactive tracers to determine the ages of streamflow

April 8, 2019- 
Watersheds store water underground in soils and weathered bedrock. How long it takes for water to flow through the subsurface to feed streams is difficult to measure but important for understanding how watersheds function. Lawrence Livermore National Laboratory (LLNL) researchers and their collaborators have studied the mixture of water ages in Providence Creek, a stream in the southern...

Diving into untouched lunar treasures

March 27, 2019- 
Nearly 50 years ago, some very special materials were transported from outer space to Earth — unopened lunar treasures rocketed back by Apollo moonwalkers between 1971 and 1972. Nine "special samples" were collected in containers during the Apollo 15, 16 and 17 missions that had indium knife-edge seals to maintain a lunar-like vacuum. Apollo mission planners devised these special sample...

International collective of scientists seeks refined understanding of climate system

March 25, 2019- 
Climate scientists at Lawrence Livermore National Laboratory (LLNL) announced today the release of new data sets that will provide fresh insights into past and future climate change. Some of these data sets come from model simulations performed at LLNL, one of the more than 40 climate research centers and consortia engaged in next-generation climate change simulations. These results have...

Solving a 50-year-old beta decay puzzle with advanced nuclear model simulations

March 19, 2019- 
For the first time, an international team including scientists at Lawrence Livermore National Laboratory (LLNL) has found the answer to a 50-year-old puzzle that explains why beta decays of atomic nuclei are slower than expected.   The findings fill a long-standing gap in physicists’ understanding of beta decay (converting a neutron into a proton and vice versa), a key process stars use to...

New climate model evaluation method can help to predict more accurate future change

March 18, 2019- 
Combining a new evaluation technique for climate models with observations could reduce the uncertainty in predicting future change. That is the result of a new study by a Lawrence Livermore National Laboratory (LLNL) scientist and collaborators who investigated the evaluation technique (called emergent constraints or ECs) in Earth System Models and found that this method may improve the...

Lab will play key role in neuro conference

March 15, 2019- 
Ten Lawrence Livermore National Laboratory (LLNL) employees will play key roles in this weekend’s 16th annual World Congress for the Society for Brain Mapping and Therapeutics (SBMT) in Los Angeles. But for two of those employees, Innovation and Partnerships Office (IPO) Deputy Director Roger Werne and computer scientist Mike Piscotty, the conference stirs strong emotions because of brain...

Biosensor may provide better cancer diagnosis

March 14, 2019- 
Lawrence Livermore National Laboratory (LLNL) researchers have developed a new biological sensor that could help clinicians better diagnose cancer and epilepsy. Biological sensors monitor small molecules, ions and protons and are vital as a medical diagnostic. Even the simplest signals, such as intracellular pH level, can provide important information for the medical community. For example...

Lab research helps uncover how beetle gut microbes serve as reactor for fuel production

March 8, 2019- 
When most people think of wood-eating insects, they imagine termites that can destroy a home or business. However, as part of a Lawrence Livermore National Laboratory (LLNL) bioenergy study, project scientist Jennifer Pett-Ridge and collaborators have learned how the digestive system of a wood-eating beetle serves as a natural mini-reactor for biofuel production. Led by Javier Ceja-Navarro...

Climate change science marks 40th anniversary of three key events that signified turning point

Feb. 25, 2019- 
During the same decade that saw the Beatles breakup, the Watergate scandal, the first Earth Day and the opening of the movie Star Wars, efforts to identify human-caused climate change were in their infancy. Three key events in the 1970s heralded the end of that infancy. The year 2019 marks the 40th anniversary of those three events. Lawrence Livermore National Laboratory (LLNL) scientists...

Death of the dinosaurs: Extreme volcanism played pivotal role in extinction, research shows

Feb. 21, 2019- 
Not by meteorite alone did the dinosaurs die off. Lawrence Livermore National Laboratory (LLNL) research scientist Kyle Samperton and colleagues present the most compelling evidence yet that massive volcanic eruptions in the Deccan Traps region of India contributed to the fall of the dinosaurs — also known as the end-Cretaceous mass extinction — approximately 66 million years ago. The...
