29-Jan-2016 Tiniest particles shrink before exploding when hit with SLAC's X-ray laser
Researchers assumed that tiny objects would instantly blow up when hit by extremely intense light from the world's most powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. But to their astonishment, these nanoparticles initially shrank instead -- a finding that provides a glimpse of the unusual world of superheated nanomaterials that could eventually also help scientists further develop X-ray techniques for taking atomic images of individual molecules.

Stan Brodsky, a professor of particle physics and astrophysics at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, has received the 2015 Pomeranchuk Prize from the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, Russia. He shares the award with Russian physicist Victor Fadin.
4-Jan-2016 Q&A: Biologist describes milestone toward a universal flu vaccine
Scientists from The Scripps Research Institute and the Crucell Vaccine Institute have now designed a protein fragment called mini-HA that stimulates the production of antibodies against a variety of influenza viruses. A key part of the work took place at the Stanford Synchrotron Radiation Lightsource, a DOE Office of Science User Facility at SLAC National Accelerator Laboratory, where the scientists used a technique called X-ray crystallography to look at the atomic structure of the mini-HA at each stage of its development.
14-Dec-2015 LUX experiment draws best picture yet of what dark matter particles cannot be
The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now scientists have significantly enhanced its ability to look for WIMPs, or weakly interacting massive particles, which are among the leading candidates for dark matter.
9-Dec-2015 To get more oomph from an electron gun, tip it with diamondoids
They sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning equipment and particle accelerators, to name a few important uses. Now scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have figured out how to increase these electron flows 13,000-fold by applying a single layer of diamondoids -- tiny, perfect diamond cages -- to an electron gun's sharp gold tip.
8-Dec-2015 Innovation boosts study of fragile biological samples at SLAC's X-ray laser
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a simple new way to study very delicate biological samples -- like proteins at work in photosynthesis and components of protein-making machines called ribosomes -- at the atomic scale using SLAC's X-ray laser.
23-Nov-2015 Atom-sized craters make a catalyst much more active
Bombarding and stretching an important industrial catalyst opens up tiny holes on its surface where atoms can attach and react, greatly increasing its activity as a promoter of chemical reactions, according to a study by scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory.
18-Nov-2015 Q&A: SLAC theorist Lance Dixon explains quantum gravity
In this Q&A, Particle Physics and Astrophysics Professor Lance Dixon of Stanford University and the Department of Energy's SLAC National Accelerator Laboratory explains one approach to developing such a theory, called quantum gravity.
17-Nov-2015 SLAC's Helen Quinn to receive 2016 Compton Medal
Helen Quinn, a professor emerita at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, will receive the 2016 Karl Taylor Compton Medal for Leadership in Physics for her contributions to science education and theoretical physics.
16-Nov-2015 X-ray microscope reveals 'solitons,' a special type of magnetic wave
Researchers used a powerful, custom-built X-ray microscope at the Department of Energy's SLAC National Accelerator Laboratory to directly observe the magnetic version of a soliton, a type of wave that can travel without resistance. Scientists are exploring whether such magnetic waves can be used to carry and store information in a new, more efficient form of computer memory that requires less energy and generates less heat.
11-Nov-2015 SLAC goes to bat for science at Discovery Day
The annual Discovery Day at AT&T Park was yet again a grand slam for science: About 35,000 visitors flocked to the ballpark of the San Francisco Giants on Nov. 7 to attend the fifth edition of the family-friendly science fair. With 150 exhibits and activities, science and technology organizations from across the Bay Area made science fun and accessible to the public.
3-Nov-2015 A record-setting way to make transparent conductors: Spread them like butter on toast
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have shown they can make flexible, transparent electrical conductors with record-high performance for use in solar cells, displays and other devices by spreading polymers on a clear surface with a tiny blade, like a knife spreading butter on toast.
2-Nov-2015 First neutrino sightings by MicroBooNE
The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter's dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
29-Oct-2015 Scientists get first glimpse of conductivity that could break size barriers for memory
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have made the first direct images showing that electrical currents can flow along the boundaries between tiny magnetic regions of a material that normally doesn't conduct electricity. The results could have major implications for magnetic memory storage.
22-Oct-2015 Stanford and SLAC celebrate Arthur Bienenstock
Arthur 'Artie' Bienenstock, professor emeritus at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, was honored with an all-day symposium in recognition of his outstanding contributions to science, academia, graduate student education and US science policy.

The American Physical Society has honored two key figures of the BABAR particle physics experiment at the Department of Energy's SLAC National Accelerator Laboratory with the 2016 W.K.H. Panofsky Prize in Experimental Particle Physics: SLAC Director Emeritus Jonathan Dorfan and California Institute of Technology Professor David Hitlin. They share the award with Stephen Olsen and Fumihiko Takasaki, two lead researchers of the Belle experiment in Japan.
