Digging deep: Harnessing the power of soil microbes for more sustainable farming

(DOE/Lawrence Berkeley National Laboratory) How will the farms of the future feed a projected 9.8 billion people by 2050? Berkeley Lab's 'smart farm' project marries microbiology and machine learning in an effort to reduce the need for chemical fertilizers and enhance soil carbon uptake, thus improving the long-term viability of the land while increasing crop yields.

Mapping battery materials with atomic precision

(DOE/Lawrence Berkeley National Laboratory) An international team led by researchers at Berkeley Lab used advanced techniques in electron microscopy to show how the ratio of materials that make up a lithium-ion battery electrode affects its structure at the atomic level, and how the surface is very different from the rest of the material.

Chemical sleuthing unravels possible path to forming life's building blocks in space

(DOE/Lawrence Berkeley National Laboratory) Scientists have used experiments at Berkeley Lab to retrace the chemical steps leading to the creation of complex hydrocarbons in space. They showed pathways to forming 2-D carbon-based nanostructures in a mix of heated gases.

Combination of old and new yields novel power grid cybersecurity tool

(DOE/Lawrence Berkeley National Laboratory) An innovative R&D project led by Berkeley Lab researchers that combines cybersecurity, machine learning algorithms and commercially available power system sensor technology to better protect the electric power grid has sparked interest from US utilities, power companies and government officials.

Can strongly lensed type 1a supernovae resolve cosmology's biggest controversy?

(DOE/Lawrence Berkeley National Laboratory) Astrophysicists at Lawrence Berkeley National Laboratory (Berkeley Lab) and University of Portsmouth discovered how to control the 'micolensing' effects of strongly lensed Type 1a Supernovae with supercomputers at NERSC. Show More Summary

Imaging individual flexible DNA 'building blocks' in 3-D

(DOE/Lawrence Berkeley National Laboratory) A team of researchers from Lawrence Berkeley National Lab (Berkeley Lab) and Ohio State University have generated 3-D images from 129 individual molecules of flexible DNA origami particles. Their work provides the first experimental verification of the theoretical model of DNA origami.

Berkeley Lab 'minimalist machine learning' algorithms analyze images from very little data

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach 'learns' much more quickly and requires far fewer images.

Solving the dark energy mystery: A new assignment for a 45-year-old telescope

(DOE/Lawrence Berkeley National Laboratory) Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.

Several Berkeley Lab scientists to present talks at 2018 AAAS Annual Meeting

(DOE/Lawrence Berkeley National Laboratory) Several scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) will present talks at the annual meeting of the American Association for the Advancement of Science, to be held Feb. Show More Summary

Scientists discover 'chiral phonons' -- atomic rotations in a 2-D semiconductor crystal

(DOE/Lawrence Berkeley National Laboratory) A research team has found the first evidence that a shaking motion in the structure of an atomically thin material possesses a naturally occurring circular rotation that could become the building block for a new form of information technology and molecular-scale machines.

Gene enhancers are important despite apparent redundancy

(DOE/Lawrence Berkeley National Laboratory) Scientists answered a long-standing question about the role of enhancers. And by better linking the genomic complement of an organism with its expressed characteristics, their work offers new insights that further the growing field of systems biology, which seeks to gain a predictive understanding of living systems.

Applying machine learning to the universe's mysteries

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab physicists and their collaborators have demonstrated that computers are ready to tackle the universe's greatest mysteries -- they used neural networks to perform a deep dive into data simulating the subatomic particle soup that may have existed just microseconds after the big bang.

New discovery could improve organic solar cell performance

(DOE/Lawrence Berkeley National Laboratory) Scientists who are members of a new energy materials-related science center based at Berkeley Lab have solved a mystery that could lead to gains in efficiency for organic solar cells.

Scientists discover material ideal for smart photovoltaic windows

(DOE/Lawrence Berkeley National Laboratory) Researchers at Berkeley Lab discovered that a form of perovskite, one of the hottest materials in solar research currently due to its high conversion efficiency, works surprisingly well asShow More Summary

Coupling experiments to theory to build a better battery

(DOE/Lawrence Berkeley National Laboratory) A Berkeley Lab-led team of researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles.

X-rays reveal 'handedness' in swirling electric vortices

(DOE/Lawrence Berkeley National Laboratory) Scientists used spiraling X-rays at Berkeley Lab to observe, for the first time, a property that gives left- or right-handedness to swirling electric patterns -- dubbed polar vortices -- in a layered material called a superlattice.

Ingredients for life revealed in meteorites that fell to Earth

(DOE/Lawrence Berkeley National Laboratory) A detailed study of blue salt crystals found in two meteorites that crashed to Earth -- which included X-ray experiments at Berkeley Lab found that they contain both liquid water and a mix of complex organic compounds including hydrocarbons and amino acids.

Real world native biocrusts: Microbial metabolism

(DOE/Lawrence Berkeley National Laboratory) Specific compounds are transformed by and strongly associated with specific bacteria in native biological soil crust (biocrust) using a suite of tools called 'exometabolomics.' Understanding how microbial communities in biocrusts adapt to harsh environments could shed light on the roles of soil microbes in the global carbon cycle.

Star mergers: A new test of gravity, dark energy theories

(DOE/Lawrence Berkeley National Laboratory) Observations and measurements of a neutron star merger have largely ruled out some theories relating to gravity and dark energy, and challenged a large class of theories.

Beta of Neurodata Without Borders software now available

(DOE/Lawrence Berkeley National Laboratory) Neuroscientists can now explore a beta version of the new Neurodata Without Borders: Neurophysiology (NWB:N 2.0) software and offer input to developers before it is fully released next yea...
