Where scientist meets machine: A fresh approach to experimental design at SLAC X-ray laser
Big leaps in technology require big leaps in design ­-- entirely new approaches that can take full advantage of everything the technology has to offer. That's the thinking behind a new initiative at the Department of Energy's SLAC National Accelerator Laboratory.

Machine learning dramatically streamlines search for more efficient chemical reactions
In theory, a catalytic reaction may follow thousands of possible paths, and it can take years to identify which one it actually takes so scientists can tweak it and make it more efficient. Now researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have taken a big step toward cutting through this thicket of possibilities.

Beyond femtoseconds
Hopefully you've discovered this week how femtosecond science provides revolutionary views of some of nature's fastest phenomena. You now know how mind-bogglingly fast a femtosecond passes, and you might be thinking things couldn't get much faster. Well, let's talk about the attosecond.

What can you study in femtoseconds? Materials
When Aaron Lindenberg was introduced to ultrafast science as a first-year grad student at UC Berkeley, he was immediately hooked. He knew he wanted to be part of a hot research field that explores nature's speediest processes and lets us see the world with different eyes.

How do you catch femtosecond light?
Gabriella Carini enjoys those little moments -- after hours and hours of testing in clean rooms, labs and at X-ray beamlines -- when she first sees an instrument work.

How do you make a femtosecond light source?
Agostino 'Ago' Marinelli first met pioneering accelerator physicist Claudio Pellegrini as an undergraduate student at the University of Rome. It was 2007, a couple of years before the Linac Coherent Light Source (LCLS) came online at SLAC, and people were abuzz about free-electron laser physics.

Why study in femtoseconds?
The text on this screen may appear stable enough, but every molecule, atom, and electron in it is in constant motion. The laws of quantum physics require that on the atomic scale nothing is ever truly at rest. Nano-sized motion also keeps us warm, cooks our food, lights our smartphones, and enables all of our senses of hearing, sight, smell, taste, and touch.

How X-rays pushed topological matter research over the top
Pioneering X-ray experiments at Berkeley Lab's Advanced Light Source (ALS) helped bring to life decades-old theories about exotic topological states of matter, and the ALS continues to play an important role in this flourishing field of research.

SLAC celebrates Femtosecond Week
Got a millionth of a billionth of a second? There's science that actually happens on this timescale. Join us online for a week of ultrafast science from April 17 to 21. Learn more about how scientists and engineers use electron beams and bright pulses of light from the Linac Coherent Light Source X-ray laser and other advanced lasers to capture some of nature's speediest processes that occur in just femtoseconds, or quadrillionths of a second.

New SLAC theory institute aims to speed research on exotic materials at light sources
A new institute at the Department of Energy's SLAC National Accelerator Laboratory is using the power of theory to search for new types of materials that could revolutionize society -- by making it possible, for instance, to transmit electricity over power lines with no loss.

Scientists watch a molecule protect itself from radiation damage
When DNA is hit with ultraviolet light, it can lose excess energy from radiation by ejecting the core of a hydrogen atom -- a single proton -- to keep other chemical bonds in the system from breaking. To gain insight into this process, researchers used X-ray laser pulses from the Linac Coherent Light Source (LCLS) at the Department of Energy's SLAC National Accelerator Laboratory to investigate how energy from light transforms a relatively simple molecule, 2-thiopyridone.

How did the proton get its spin?
Scientists once thought proton spin was simple to understand. However, after experiments in the 1980s proved their ideas wrong, researchers have been working to understand how the proton's components contribute to its spin. Scientists use the unique capabilities of the Relativistic Heavy Ion Collider and the Continuous Electron Beam Accelerator Facility, both DOE Office of Science user facilities, to explore this fundamental phenomenon.

New device produces hydrogen peroxide for water purification

Producing and distributing hydrogen peroxide is a challenge in many parts of the world. Now scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have created a small device for hydrogen peroxide production that could be powered by renewable energy sources, like conventional solar panels.

Physicists move closer to listening in on sub-atomic conversation
Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles' gab fests and learn more about how they stick together to build our visible universe. The first complex calculations of a particle called the sigma have been carried out and published in Physical Review Letters.
