X-rays show how periods of stress changed an ice age hyena to the bone
Researchers mapped trace elements within Pleistocene fossils to learn about the life of a long-extinct subspecies of spotted hyena.
Researchers create most complete high-res atomic movie of photosynthesis to date
In a major step forward, SLAC’s X-ray laser captures all four stable states of the process that produces the oxygen we breathe, as well as fleeting steps in between. The work opens doors to understanding the past and creating a greener future.
Shunned by Microbes, Organic Carbon Can Resist Breakdown in Underground Environments
A new study reveals that organic matter whose breakdown would yield only minimal energy for hungry microorganisms preferentially builds up in floodplains, illuminating a new mechanism of carbon sequestration.
New Device Produces Hydrogen Peroxide for Water Purification
Scientists at SLAC and Stanford have identified active carbon catalysts and developed an electrochemical cell designed to purify water in small villages.
SLAC Study Helps Explain Why Uranium Persists in Groundwater at Former Mining Sites
The contaminant binds to organic matter in sediments, which increases persistence in groundwater.
Eureka Moment Leads to New Method of Studying Environmental Toxins
A technique for probing the surface of particles revealed how toxins move from the soil to groundwater.
SLAC, Stanford Gadget Grabs More Solar Energy to Disinfect Water Faster
Researchers at SLAC and Stanford have created a nanostructured device, about half the size of a postage stamp, that harnesses more of the sun's spectrum of light to disinfect water much faster than with ultraviolet rays alone.
Stanford, SLAC Play Key Role in New DOE Battery Consortium
The White House announced $50 million in funding for ‘Battery500’, a five year effort, as part of a package of initiatives to accelerate adoption of electric vehicles in the U.S.
SLAC Scientists Search for New Ways to Deal with U.S. Uranium Ore Processing Legacy
In an important step toward handling the nation’s uranium milling legacy, researchers try to understand why contamination at remediated uranium processing sites continues to persist at dangerously high levels.
