(Phys.org) -- Researchers at the SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard.

Scientists working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and opening the door to a new range of scientific discovery.

Researchers working at the SLAC National Accelerator Laboratory have used the world's most powerful X-ray laser to create and probe a two-million-degree piece of matter in a controlled way for the first time. This feat, reported today in Nature, takes scientists a significant step forward in understanding the most extreme matter found in the hearts of stars and giant planets, and could help experiments aimed at recreating the nuclear fusion process that powers the sun.

Tiny particles are making a big difference in the world of cancer therapy. And SLAC physicists—experts in particle transport—are using computer simulations to make those therapies safer.

(PhysOrg.com) -- By finding a clever way to use the Earth itself as a scientific instrument, members of a SLAC-led research team turned the Fermi Gamma-ray Space Telescope into a positron detector – and confirmed a startling discovery from 2009 that found an excess of these antimatter particles in cosmic rays, a possible sign of dark matter.

The great thing about SLAC’s Linac Coherent Light Source is that it churns out incredible volumes of data about things no one has ever seen before, such as snapshots of individual viruses.

(PhysOrg.com) -- A new x-ray microscopy technique that allows scientists to make images 60 times faster than before has been developed by an Australian research team including Garth Williams, who is now an instrument scientist at SLAC’s Linac Coherent Light Source. The method, called polychromatic coherent diffractive imaging, or polyCDI, will also enable sharper and more accurate images of floppy biological molecules and fast-moving materials structures.

(PhysOrg.com) -- As conventional accelerators like CERN's Large Hadron Collider grow ever more vast and expensive, the best hope for the high-energy machines of the future may lie in "tabletop" accelerators like BELLA (the Berkeley Lab Laser Accelerator), now being built by the LOASIS program at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab)
