Scientists based in Palo Alto, California, have accomplished a major feat: They have produced brilliant X-ray light from a device just a fraction of the standard size. The advance could transform numerous fields of biomedical research by vastly improving access to a key resource for studying the properties of molecules.
Researchers who want to know the structures of molecules, such as proteins, use synchrotrons--facilities as big as football stadiums that produce intense X-ray beams. But because of the size and cost of synchrotrons, only a few exist. To make the technology more widely available, scientists at Lyncean Technologies, Inc., have been constructing a synchrotron prototype since 2004 that would produce X-ray beams in the space of a small office and that could be installed at many research institutions. The prototype, called the Compact Light Source (CLS), demonstrated its feasibility by generating its first X-ray beam on February 23, 2006.
The scientists soon will begin using the prototype to collect experimental data. The first Beta CLS will be installed at the Scripps Research Institute in La Jolla, California, as part of a Protein Structure Initiative (PSI) center aimed at accelerating the determination of protein structures.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
