Ribosome Research Takes Shape at SLAC

In a new state-of-the-art lab at SLAC National Accelerator Laboratory, components of ribosomes – tiny biological machines that make new proteins and play a vital role in gene expression and antibiotic treatments – form crystals in a liquid solution.

Signs at the lab's entryway warn of the potential for contamination – these delicate samples can be damaged by human touch, a sneeze or a dust particle.

Annual SSRL Award Honors Former Stanford Grad Student

Jonathan Rivnay, a former Stanford graduate student who is now a postdoctoral fellow at the Center of Microelectronics in Provence, France, will receive this year's William E. and Diane M. Spicer Young Investigator Award in recognition of his synchrotron studies of organic semiconductors.

SPEAR-heading X-ray Science for 40 Years

Last Saturday marked the 40th anniversary of an historic event: In 1973, a team of research pioneers extracted hard X-rays for the first time from SLAC's SPEAR accelerator. Like X-rays from an X-ray tube, the radiation generated by SPEAR can deeply penetrate a large variety of materials and probe their inner structures. However, SPEAR's X-rays are significantly more intense and unlock the possibility for brand new science.

Research Paints New Picture of 'Dinobird' Feathers

The first complete chemical analysis of feathers from Archaeopteryx, a famous fossil linking dinosaurs and birds, reveals that the feathers were patterned—light in color, with a dark edge and tip—rather than all black, as previously thought.

SLAC X-rays Resurrect 200-year-old Opera

At first glance the beautifully bound 1797 Luigi Cherubini opera Médée looks like an impeccably preserved relic of opera's golden age. However, flip to the final pages of the aria "Du trouble affreux qui me dévore" ("The terrible disorder that consumes me") and you see the problem: Thick smudges of carbon completely black out the closing lines.

Printing Innovations Provide 10-fold Improvement in Organic Electronics

Through innovations to a printing process, researchers have made major improvements to organic electronics – a technology in demand for lightweight, low-cost solar cells, flexible electronic displays and tiny sensors. The printing method is fast and works with a variety of organic materials to produce semiconductors of strikingly higher quality than what has so far been achieved with similar methods.

X-ray Laser Explores How to Write Data with Light

Using laser light to read and write magnetic data by quickly flipping tiny magnetic domains could help keep pace with the demand for faster computing devices.

Now experiments with SLAC's Linac Coherent Light Source (LCLS) X-ray laser have given scientists their first detailed look at how light controls the first trillionth of a second of this process, known as all-optical magnetic switching.

Unexpected Allies Help Bacteria Clean Uranium From Groundwater

Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. Their initial goal was to discover how the bacteria do it and determine the best way to help, but during the course of their research the team made an even more important discovery: Nature thinks bigger than that.

An Impressive and Growing Array of Lasers at SLAC

In less than a decade, SLAC has built up an impressive array of dozens of laser systems – and a team of laser scientists and engineers – with capabilities that make it one of the most cutting-edge national laboratories under the U.S. Department of Energy.
