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.

X-rays reveal chirality in swirling electric vortices

Scientists used spiraling X-rays at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to observe, for the first time, a property that gives handedness to swirling electric patterns – dubbed polar vortices – in a synthetically layered material.

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...

ESnet's Petascale DTN project speeds up data transfers between leading HPC centers

(DOE/Lawrence Berkeley National Laboratory) A new Petascale Data Transfer Node project aims to to achieve regular disk-to-disk, end-to-end transfer rates of one petabyte per week between major supercomputing facilities, which translates to achievable throughput rates of about 15 Gbps on real world science data sets.

Studying gas mask filters so people can breathe easier

In research that could lead to better gas mask filters, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have been putting the X-ray spotlight on composite materials in respirators used by the military, police, and first responders, and the results have been encouraging.

Watching a quantum material lose its stripes

(DOE/Lawrence Berkeley National Laboratory) In quantum materials, periodic stripe patterns can be formed by electrons coupled with lattice distortions. To capture the extremely fast dynamics of how such atomic-scale stripes melt and form, Berkeley Lab scientists used femtosecond-scale laser pulses at terahertz frequencies. Along the way, they found some unexpected behavior.

'Holy grail' for batteries: Solid-state magnesium battery a big step closer

(DOE/Lawrence Berkeley National Laboratory) A team of Department of Energy scientists at the Joint Center for Energy Storage Research has discovered the fastest magnesium-ion solid-state conductor, a major step towards making solid-state magnesium-ion batteries that are both energy dense and safe.

Research becomes reality in study of fire impact on sonoma water resources

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) spent a decade developing world-class modeling and monitoring capabilities to pinpoint factors behind the success of Sonoma's riverbank filtration system. Show More Summary

How the Earth stops high-energy neutrinos in their tracks

(DOE/Lawrence Berkeley National Laboratory) In an analysis of data from an experiment embedded in Antarctic ice, a research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos -- particles that only very rarely interact with matter.

X-Rays Reveal the Biting Truth About Parrotfish Teeth

A study by scientists – including those at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) – has revealed a chain mail-like woven microstructure that gives parrotfish teeth their remarkable bite and resilience.

To find new biofuel enzymes, it can take a microbial village

A new study led by researchers at the Department of Energy's Joint BioEnergy Institute (JBEI), based at Lawrence Berkeley National Laboratory (Berkeley Lab), demonstrates the importance of microbial communities as a source of stable enzymes that could be used to convert plants to biofuels.

To find new biofuel enzymes, it can take a microbial village

(DOE/Lawrence Berkeley National Laboratory) In search of new plant enzymes? Try looking in compost. Researchers at JBEI have demonstrated the importance of microbial communities as a source of stable enzymes that could be used to convert plants to biofuels. This approach yields robust enzymes that researchers can't easily obtain from isolates.

Fuel cell x-ray study details effects of temperature and moisture on performance

(DOE/Lawrence Berkeley National Laboratory) To find the right balance of moisture and temperature in a specialized type of hydrogen fuel cell, Berkeley Lab scientists have used X-rays to explore the inner workings of its components at tiny scales.
