Machine learning method accurately predicts metallic defects

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

For the first time, Berkeley Lab researchers have built and trained machine learning algorithms to predict defect behavior in certain intermetallic compounds with high accuracy. This method will accelerate research of new advanced alloys and lightweight new materials for applications spanning automotive to aerospace and much more.

SLAC study helps explain why uranium persists in groundwater at former mining sites

DOE/SLAC National Accelerator Laboratory

A recent study led by scientists at the Department of Energy's SLAC National Accelerator Laboratory helps describe how uranium cycles through the environment at former uranium mining sites and why it can be difficult to remove.

Berkeley Lab gets $4.6 million in functional genomics catalog project

DOE/Lawrence Berkeley National Laboratory
Grant and Award Announcement

Berkeley Lab is set to receive nearly $4.6 million over four years as part of an ongoing, federally funded project to create a comprehensive catalog for fundamental genomics research. This latest expansion of the Encyclopedia of DNA Elements (ENCODE) project, or ENCODE 4, is funded by the National Human Genome Research Institute.

Simulations reveal the invisible chaos of superluminous supernovae

DOE/Lawrence Berkeley National Laboratory

To better understand the physical conditions that create superluminious supernova, astrophysicists are running 2-D simulations of these events using supercomputers at the Department of Energy's National Energy Research Scientific Computing Center and the Lawrence Berkeley National Laboratory (Berkeley Lab) developed CASTRO code.

High-resolution imaging reveals new understanding of battery cathode particles

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Using advanced imaging techniques, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have been able to observe what exactly happens inside a cathode particle as lithium-ion batteries are charged and discharged.

Scientists determine precise 3-D location, identity of all 23,000 atoms in a nanoparticle

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists used one of the world's most powerful electron microscopes to map the precise location and chemical type of 23,000 atoms in an extremely small particle made of iron and platinum. Insights gained from the particle's structure could lead to new ways to improve its magnetic performance for use in high-density, next-generation hard drives.

Taking down a giant: 699 tons of SLAC's accelerator removed for upgrade

DOE/SLAC National Accelerator Laboratory

For the first time in more than 50 years, a door that is opened at the western end of the historic linear accelerator at the Department of Energy's SLAC National Accelerator Laboratory casts light on four empty walls stretching as far as the eye can see. This end of the linac -- a full kilometer of it -- has been stripped of all its equipment both above and below ground.

Art Rosenfeld, California's godfather of energy efficiency, dies at 90

DOE/Lawrence Berkeley National Laboratory

Art Rosenfeld, a Lawrence Berkeley National Laboratory Distinguished Scientist Emeritus who is also known as California's 'godfather' of energy efficiency and who has been credited with being personally responsible for billions of dollars in energy savings, died Friday at his home in Berkeley, California. He was 90.

For this metal, electricity flows, but not the heat

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley scientists have discovered that electrons in vanadium dioxide can conduct electricity without conducting heat, an exotic property in an unconventional material. The characteristic could lead to applications in thermoelectrics and window coatings.

Images show cytofilaments linking cell nucleus to extracellular environment

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

New images are providing the first visual evidence of a long-postulated physical link by which genes can receive mechanical cues from its microenvironment. Created by integrating six different imaging techniques, the images show thread-like cytofilaments reaching into and traversing a human breast cell's chromatin-packed nucleus.
