Public Release: 19-Jan-2018 Superconducting X-ray laser takes shape in Silicon Valley
An area known for high-tech gadgets and innovation will soon be home to an advanced superconducting X-ray laser that stretches 3 miles in length, built by a collaboration of national laboratories. On Jan. 19, the first section of the machine's new accelerator arrived by truck at SLAC National Accelerator Laboratory in Menlo Park after a cross-country journey that began in Batavia, Ill., at Fermi National Accelerator Laboratory.

Nature Communications Scientists discover path to improving game-changing battery electrode
Researchers from Stanford University, two Department of Energy national labs and the battery manufacturer Samsung created a comprehensive picture of how the same chemical processes that give cathodes their high capacity are also linked to changes in atomic structure that sap performance.

Science Scientists get first close-ups of finger-like growths that trigger battery fires
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have captured the first atomic-level images of finger-like growths called dendrites that can pierce the barrier between battery compartments and trigger short circuits or fires. Dendrites and the problems they cause have been a stumbling block on the road to developing new types of batteries that store more energy so electric cars, cell phones, laptops and other devices can go longer between charges.
Public Release: 14-Sep-2017 SLAC-led project will use AI to prevent or minimize electric grid failures
A project led by the Department of Energy's SLAC National Accelerator Laboratory will combine artificial intelligence with massive amounts of data and industry experience from a dozen U.S. partners to identify places where the electric grid is vulnerable to disruption, reinforce those spots in advance and recover faster when failures do occur.

Nature Artificial intelligence analyzes gravitational lenses 10 million times faster
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have for the first time shown that neural networks -- a form of artificial intelligence -- can accurately analyze the complex distortions in spacetime known as gravitational lenses 10 million times faster than traditional methods.

Nature Astronomy Scientists create 'diamond rain' that forms in the interior of icy giant planets
In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe 'diamond rain' for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.

American Physical Society Division of Particles and Fields Meeting Standard model of the universe withstands most precise test by Dark Energy Survey
Astrophysicists have a fairly accurate understanding of how the universe ages: that's the conclusion of new results from the Dark Energy Survey (DES), a large international science collaboration, including researchers from the Department of Energy's SLAC National Accelerator Laboratory, that put models of cosmic structure formation and evolution to the most precise test yet.

Nature Scientists watch 'artificial atoms' assemble into perfect lattices with many uses
Some of the world's tiniest crystals are known as 'artificial atoms' because they can organize themselves into structures that look like molecules, including 'superlattices' that are potential building blocks for novel materials. Now scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first observation of these nanocrystals rapidly forming superlattices while they are themselves still growing.

Science Advances Atomic movies may help explain why perovskite solar cells are more efficient
Experiments with a powerful 'electron camera' at the Department of Energy's SLAC National Accelerator Laboratory have discovered that light whirls atoms around in perovskites, potentially explaining the high efficiency of these next-generation solar cell materials and providing clues for making better ones.

Science Scientists get first direct look at how electrons 'dance' with vibrating atoms
Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons move in sync with atomic vibrations rippling through an exotic material, as if they were dancing to the same beat.

Nature The world's most powerful X-ray laser beam creates 'molecular black hole'
When scientists at the Department of Energy's SLAC National Accelerator Laboratory focused the full intensity of the world's most powerful X-ray laser on a small molecule, they got a surprise: a single laser pulse stripped all but a few electrons out of the molecule's biggest atom from the inside out, leaving a void that started pulling in electrons from the rest of the molecule, like a black hole gobbling a spiraling disk of matter.

Nature X-ray study reveals long-sought insights into potential drug target
X-ray studies done in part at the Department of Energy's SLAC National Accelerator Laboratory have produced surprising insights into the workings of a hormone receptor associated with blood pressure regulation. Researchers believe it could be a target for new medicines related to cardiovascular conditions, neuropathic pain and tissue growth.
