18-Mar-2015 Scientists watch quantum dots 'breathe' in response to stress
Researchers at the Department of Energy's SLAC National Accelerator Laboratory watched nanoscale semiconductor crystals expand and shrink in response to powerful pulses of laser light. This ultrafast 'breathing' provides new insight about how such tiny structures change shape as they start to melt -- information that can help guide researchers in tailoring their use for a range of applications.
10-Mar-2015 Possible rare dwarf galaxies found orbiting Milky Way
Researchers have discovered a set of eight celestial objects orbiting our home galaxy, the Milky Way, that appear to be rare dwarf satellite galaxies. Dwarf galaxies are the smallest known galaxy structures and may hold the key to understanding dark matter.
9-Mar-2015 Scientists gather at SLAC to prepare for Large Synoptic Survey Telescope
When the Large Synoptic Survey Telescope begins in 2022 to image the entire southern sky from a mountaintop in Chile, it will produce the widest, deepest and fastest views of the night sky ever observed -- and a flood of 6 million gigabytes of data per year that are expected to provide new insights into dark matter, dark energy and other cosmic mysteries.
2-Mar-2015 Giant virus revealed in 3-D using X-ray laser
For the first time, researchers have produced a 3-D image revealing part of the inner structure of an intact, infectious virus, using a unique X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. The virus, called Mimivirus, is in a curious class of 'giant viruses' discovered just over a decade ago.
26-Feb-2015 SLAC assumes a leading role for SuperCDMS SNOLAB
Deciphering the nature of dark matter -- the mysterious substance that makes up about 85 percent of the matter in the universe yet has never been directly seen -- is one of the most important quests in particle physics today. As the lead laboratory in the Department of Energy for the SuperCDMS SNOLAB project, SLAC National Accelerator Laboratory is playing an important role in tracking it down.
25-Feb-2015 SLAC-led research team bends highly energetic electron beam with crystal
An international team of researchers working at the Department of Energy's SLAC National Accelerator Laboratory has demonstrated that a bent silicon crystal can bend the paths of focused, very energetic electron beams much more than magnets used today. The method could be of interest for particle accelerator applications such as next-generation X-ray lasers that will help scientists unravel atomic structures and motions in unprecedented detail.
20-Feb-2015 New programs enhance SIMES role in studying exotic new materials
