X-ray laser acts as tool to track life's chemistry

Dec. 5, 2014- 
An international research team that includes researchers from Lawrence Livermore National Laboratory has captured the highest-resolution protein snapshots ever taken with an X-ray laser, revealing how a key protein in a photosynthetic bacterium changes shape when hit by light.Human biology is a massive collection of chemical reactions and all involve proteins, known as the molecules of life...

Lawrence Livermore researchers delve into airborne particulates

June 27, 2012- 
For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace. The structure of micron-size particulate matter is important in a wide range of fields from toxicology to climate science (tobacco smoke and oil smoke particles...

Graphite enters different states of matter in ultrafast experiment

May 15, 2012- 
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues...
