TODAY’S STUDY: A Plan To Help Utilities Perform Better

State Performance-Based Regulation Using Multiyear Rate Plans for U.S. Electric Utilities Mark Newton Lowry, Matt Makos, and Jeff Deason, July 2017 (Grid Modernization Consortium/Lawrence Berkeley National Laboratory/U.S. DepartmentShow More Summary

Making polymer chemistry 'click'

(DOE/Lawrence Berkeley National Laboratory) A team including Berkeley Lab scientists has developed a faster and easier way to make a class of sulfur-containing plastics that will lower the cost of large-scale production.

'Hindcasting' study investigates the extreme 2013 Colorado flood

(DOE/Lawrence Berkeley National Laboratory) Using a publicly available climate model, Berkeley Lab researchers 'hindcast' the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colo. and found that climate change attributed to human activity made the storm much more severe than would otherwise have occurred.

Berkeley Lab to lead multimillion-dollar geothermal energy project

(DOE/Lawrence Berkeley National Laboratory) The Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) will lead a new $9 million project aimed at removing technical barriers to commercialization of enhanced geothermal systems (EGS), a clean energy technology with the potential to power 100 million American homes.

A way to speed up reaction discoveries using automation

(—A pair of researchers with the University of California and Lawrence Berkeley National Laboratory has found a way to automate reaction discoveries, thereby speeding up the process. In their paper published in the journal Science, Konstantin Troshin and John Hartwig describe their process, how well it works, and a discovery they have already made using it.

Shading and lighting retrofits slash energy use in New York 'Living Lab' office demonstration

By using advanced lighting and automated shades, scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas.

New Berkeley lab algorithms extract biological structure from limited data

(DOE/Lawrence Berkeley National Laboratory) A new Berkeley Lab algorithmic framework called multi-tiered iterative phasing (M-TIP) utilizes advanced mathematical techniques to determine 3-D molecular structure of important nanoobjects like proteins and viruses from very sparse sets of noisy, single-particle data.

New studies of ancient concrete could teach us to do as the Romans did

(DOE/Lawrence Berkeley National Laboratory) A new look inside 2,000-year-old Roman concrete has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time.

Study on human skin microbiome finds archaea abundance associated with age

It turns out your skin is crawling with single-celled microorganisms—and they're not just bacteria. A study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Medical University of Graz has found that the skin microbiome also contains archaea, a type of extreme-loving microbe, and that the amount of it varies with age.

What's on your skin? Archaea, that's what

(DOE/Lawrence Berkeley National Laboratory) It turns out your skin is crawling with single-celled microorganisms -- and they're not just bacteria. A study by the Department of Energy's Lawrence Berkeley National Laboratory (BerkeleyShow More Summary

Record-setting seismic simulations run on the Cori supercomputer

Record-setting seismic simulations run earlier this year on the Cori supercomputer at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) were the subject of two presentations at the ISC High Performance conference in Frankfurt, Germany this week.

X-ray technique provides a new window into exotic properties of an atomically thin material

An international team of researchers, working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, fabricated an atomically thin material and measured its exotic and durable properties that make it a promising candidate for a budding branch of electronics known as "spintronics."

New class of 'soft' semiconductors could transform HD displays

A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites is capable of emitting multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers.

Researchers find new mechanism for genome regulation

(DOE/Lawrence Berkeley National Laboratory) The mechanisms that separate mixtures of oil and water may also help the organization of a part of our DNA called heterochromatin, according to a new Berkeley Lab study. Researchers found that...Show More Summary

New prototypes for superconducting undulators show promise for more powerful, versatile X-ray beams

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Argonne National Laboratory have collaborated to design, build and test two devices that utilize different superconducting materials and could make X-ray lasers more powerful, versatile, compact and durable.

Sound waves direct particles to self-assemble, self-heal

(DOE/Lawrence Berkeley National Laboratory) Berkeley Lab scientists have demonstrated how floating particles will assemble and synchronize in response to acoustic waves. Their simple experiment provides a new framework for studying how seemingly lifelike behaviors emerge in response to external forces. Show More Summary

Keeping California's natural gas system safe

(DOE/Lawrence Berkeley National Laboratory) The massive natural gas leak at Aliso Canyon shined a light on California's aging natural gas infrastructure. And five years of extreme drought also exacted its toll on transmission pipelines. Show More Summary

A seaweed derivative could be just what lithium-sulfur batteries need

(DOE/Lawrence Berkeley National Laboratory) Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists...Show More Summary

Researchers find a surprise just beneath the surface in carbon dioxide experiment

(DOE/Lawrence Berkeley National Laboratory) An X-ray technique, coupled with theoretical work, revealed how oxygen atoms embedded very near the surface of a copper sample had a more dramatic effect on the early stages of the reaction with carbon dioxide (CO2) than earlier theories could account for.
