Dead or alive: microorganisms in soil shape the global carbon cycle

March 3, 2022- 
Whether dead or alive, soil microorganisms play a major role in the biogeochemical cycling of carbon in the terrestrial biosphere. But what is the specific role of death for the bacteria, fungi and microfauna that make up the soil microbiome? That is the topic of a new review by Lawrence Livermore National Laboratory (LLNL) scientists and collaborators. The article, appearing in Nature...

Putting the pedal to the metal crossing the solid-liquid interface

Feb. 24, 2022- 
Most metal alloys are prone to corrosion, which costs hundreds of billions of dollars of damage annually in the U.S. alone. Accurately predicting corrosion rates is a long-standing goal of corrosion science, but these rates depend strongly on the specific operating environment. At the atomic scale, these environmental factors are associated with how quickly and easily metal ions dissolve and...

Researchers take closer look at stimulated Brillouin scattering

Feb. 18, 2022- 
A major cost of running the National Ignition Facility (NIF) is managing and mitigating laser-induced damage to optics as the laser beams propagate to the target.  Another damage mechanism stems from stimulated Brillouin scattering (SBS) as light travels back from the target and with nearly the same wavelength as the incoming light. This SBS has the potential to cause additional damage...

Understanding the mystery of why particles cluster in turbulent flows

Feb. 16, 2022- 
New research conducted at Lawrence Livermore National Laboratory (LLNL) analyzes three-dimensional particle-laden, isotropic turbulence to develop an understanding of inertial particle dynamics from a kinetic energy perspective. Particle-laden flows are found in a variety of applications such as rain droplets in clouds, wind-driven sand dune sprays, fluidized bed reactors and soot...

LLNL team models COVID-19 disease progression and identifies risk factors

Feb. 15, 2022- 
A Lawrence Livermore National Laboratory (LLNL) team has developed a comprehensive dynamic model of COVID-19 disease progression in hospitalized patients, finding that risk factors for complications from the disease are dependent on the patient’s disease state. Using a machine learning algorithm on a dataset of electronic health records (EHRs) from more than 1,300 hospitalized COVID-19...

Where on Earth did the water come from?

Feb. 14, 2022- 
Earth’s supply of water is incredibly important for its ability to sustain life, but where did that water come from? Was it present when Earth formed or was it delivered later by meteorites or comets from outer space? The source of Earth’s water has been a longstanding debate and Lawrence Livermore National Laboratory (LLNL) scientists think they have the answer — and they found it by...
