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.

Origin of Milky Way's hypothetical dark matter signal may not be so dark
A mysterious gamma-ray glow at the center of the Milky Way is most likely caused by pulsars. The findings cast doubt on previous interpretations of the signal as a potential sign of dark matter.

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.

Researchers use world's smallest diamonds to make wires 3 atoms wide
Scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have discovered a way to use diamondoids -- the smallest possible bits of diamond -- to assemble atoms into the thinnest possible electrical wires, just three atoms wide.

New, detailed snapshots capture photosynthesis at room temperature
New X-ray methods at the Department of Energy's SLAC National Accelerator Laboratory have captured the highest resolution room-temperature images of the protein complex photosystem II, which allows scientists to closely watch how water is split during photosynthesis at the temperature at which it occurs naturally.

X-ray laser gets first real-time snapshots of a chemical flipping a biological switch
Scientists have used the powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to make the first snapshots of a chemical interaction between two biomolecules -- one that flips an RNA 'switch' that regulates production of proteins, the workhorse molecules of life.

SLAC's high-speed 'electron camera' films atomic nuclei in vibrating molecules
An ultrafast 'electron camera' at the Department of Energy's SLAC National Accelerator Laboratory has made the first direct snapshots of atomic nuclei in molecules that are vibrating within millionths of a billionth of a second after being hit by a laser pulse. The method, called ultrafast electron diffraction, could help scientists better understand the role of nuclear motions in light-driven processes that naturally occur on extremely fast timescales.

SLAC, Stanford gadget grabs more solar energy to disinfect water faster
Researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have created a nanostructured device, about half the size of a postage stamp, that disinfects water much faster than the UV method by also making use of the visible part of the solar spectrum, which contains 50 percent of the sun's energy.
