16-Feb-2017 Protein structure solved from smallest crystals yet
An international team of scientists used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to determine the structure of an insect virus's crystalline protein 'cocoon.'
31-Jan-2017 Taking down a giant: 699 tons of SLAC's accelerator removed for upgrade
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.
11-Jan-2017 Sketching out magnetism with electricity
In a proof-of-concept study published in Nature Physics, researchers drew magnetic squares in a nonmagnetic material with an electrified pen and then 'read' this magnetic doodle with X-rays.
4-Jan-2017 SLAC study: Light can switch on topological materials
Theoretical physicists at the Department of Energy's SLAC National Accelerator Laboratory used computer simulations to show how special light pulses could create robust channels where electricity flows without resistance in an atomically thin semiconductor.
30-Nov-2016 Q&A: Simon Bare catalyzes new chemistry effort at SLAC
Simon Bare, who joined the Department of Energy's SLAC National Accelerator Laboratory in April, spent 30 years as an industrial chemist investigating how catalysts work. Now, as co-director of the Chemistry and Catalysis Division at the lab's Stanford Synchrotron Radiation Lightsource (SSRL), his goal is to build on research strengths at SLAC and Stanford University to create a West Coast center for catalyst research and define new research directions.
28-Nov-2016 'Brighter than a billion suns': SLAC studies featured in TEDx Talk
Phil Manning and his colleagues have used synchrotron light for nearly a decade to help interpret the chemical signatures locked within fossilized life. Bright X-rays have allowed them to study fossilized worm burrows, recreate pigment patterns in ancient bird feathers, see how Jurassic dinosaur bones heal and image the living chemistry of 50-million year old plant fossils.
3-Nov-2016 SLAC, Berkeley Lab researchers prepare for scientific computing on the exascale
Researchers at the Department of Energy's SLAC National Accelerator Laboratory are playing key roles in two recently funded computing projects with the goal of developing cutting-edge scientific applications for future exascale supercomputers that can perform at least a billion billion computing operations per second -- 50 to 100 times more than the most powerful supercomputers in the world today.
28-Oct-2016 Peek behind the scenes at SLAC's Stanford Synchrotron Radiation Lightsource
Engineering teams at the Department of Energy's SLAC National Accelerator Laboratory took advantage of the lull in experiments to make important upgrades during a recent routine beam shutdown at the Stanford Synchrotron Radiation Lightsource (SSRL). The newly outfitted beamlines will help visiting researchers and SLAC scientists run experiments using the synchrotron's extremely bright X-ray radiation.
12-Oct-2016 X-rays reveal artistry in an ancient vase
Under beams of X-rays, the colors of art become the colors of chemistry. The mysterious blacks, reds and whites of ancient Greek pottery can be read in elements -- iron, potassium, calcium and zinc -- and art history may be rewritten.
Theoretical physicist James D. 'BJ' Bjorken, a professor emeritus at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, will share the 2017 Robert R. Wilson Prize for Achievement in the Physics of Particle Accelerators for groundbreaking theoretical work that helped researchers understand and cope with an important constraint on the intensity and focus of particle beams in accelerators.
7-Oct-2016 Q&A: SLAC cosmology research featured in Terrence Malick's 'Voyage of Time'
Terrence Malick's science documentary 'Voyage of Time' features two scenes contributed by visualization expert Ralf Kaehler and astrophysicist Tom Abel from the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), a joint institute of Stanford University and the Department of Energy's SLAC National Accelerator Laboratory.
2-Sep-2016 SLAC Summer Institute students envision a new energy frontier
Over a hundred physicists from around the world came to the Department of Energy's SLAC National Accelerator Laboratory for two weeks in August to attend the 44th SLAC Summer Institute (SSI) on 'New Horizons on the Energy Frontier.'
30-Aug-2016 A virtual flight through a catalyst particle finds evidence of poisoning
Merging two powerful 3-D X-ray techniques, a team of researchers from the Department of Energy's SLAC National Accelerator Laboratory and Utrecht University in the Netherlands revealed new details of a process known as metal poisoning that clogs the pores of catalyst particles used in gasoline production, causing them to lose effectiveness.
29-Aug-2016 Poof! The weird case of the X-ray that came out blank
Imagine getting a medical X-ray that comes out blank -- as if your bones had vanished. That's what happened when scientists cranked up the intensity of the world's first X-ray laser, at the Department of Energy's SLAC National Accelerator Laboratory, to get a better look at a sample they were studying: The X-rays seemed to go right through it as if it were not there.
26-Aug-2016 Undergraduate interns learn from summer research
Thirty undergraduate students from around the country conducted hands-on research at SLAC this summer through the Department of Energy's Science Undergraduate Laboratory Internship (SULI) program.
23-Aug-2016 Aleksandra Vojvodic named MIT Tech Review Innovator Under 35
Aleksandra Vojvodic has been named one of MIT Technology Review's 2016 Innovators Under 35, which honors exceptionally talented technologists whose work has great potential to transform the world. A staff scientist at the Department of Energy's SLAC National Accelerator Laboratory, she has spent the past six years working at the SUNCAT Center for Interface Science and Catalysis, where she uses theory and computation to help design better catalysts for reactions that generate and store clean energy.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
