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.

For Superionic Material, Smaller is Better

A material that could enable faster memory chips and more efficient batteries can switch between high and low ionic conductivity states much faster than previously thought, SLAC and Stanford researchers have determined. The key is to use extremely small chunks of it.

Surprising Competition Found in High-Temperature Superconductors

A team led by SLAC and Stanford scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures.

The materials in question are high-temperature superconductors, which conduct electricity perfectly with no resistance when cooled below minus 100 degrees Celsius. 

Study Provides Recipe for 'Supercharging' Atoms with X-ray Laser

Menlo Park, Calif. — Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low.

Stanford-SLAC Team Uses X-ray Imaging to Observe Running Batteries in Real Time

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost.

X-ray Laser Probes Biomolecules to Individual Atoms

An international team led by the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory has proved how the world's most powerful X-ray laser can assist in cracking the structures of biomolecules, and in the processes helped to pioneer critical new investigative avenues in biology.
