Six weighty facts about gravity
Gravity: we barely ever think about it, at least until we slip on ice or stumble on the stairs. To many ancient thinkers, gravity wasn't even a force -- it was just the natural tendency of objects to sink toward the center of Earth, while planets were subject to other, unrelated laws.

World's fastest electron diffraction snapshots of atomic motions in gases
Scientists have made a significant advance toward making movies of extremely fast atomic processes with potential applications in energy production, chemistry, medicine, materials science and more. Using a superfast, high-resolution 'electron camera,' a new instrument for ultrafast electron diffraction (UED) at the Department of Energy's SLAC National Accelerator Laboratory, researchers have captured the world's fastest UED images of nitrogen molecules rotating in a gas, with a record shutter speed of 100 quadrillionths of a second.

New catalyst is 3 times better at splitting water
With a combination of theory and clever, meticulous gel-making, scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of Toronto have developed a new type of catalyst that's three times better than the previous record-holder at splitting water into hydrogen and oxygen -- the vital first step in making fuels from renewable solar and wind power.

New satellite with superior X-ray vision launched
Although the star-covered night sky is regarded by many as a synonym of serenity, the cosmos is in fact a rather hostile place. It hosts many extreme environments that would instantaneously eradicate any life nearby. A new space mission is about to reveal this violent nature in greater detail than ever before: on Feb. 17, the Japan Aerospace Exploration Agency launched its ASTRO-H satellite -- a very precise and sensitive eye for X-rays emerging from hot and energetic processes in space.

Three ways to bust ghostly dark matter
Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth's surface, underground and in space. Researchers from the Department of Energy's SLAC National Accelerator Laboratory will take part in a discussion of the global search for dark matter particles at this year's AAAS Annual Meeting, to be held Feb. 11-15 in Washington, D.C.

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.

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.

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.

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.

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.

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.
