(PhysOrg.com) -- Researchers at Oregon State University have discovered a way to make a low-cost material that might accomplish negative refraction of light and other radiation – a goal first theorized in 1861 by a giant of science, Scottish physicist James Maxwell, that has still eluded wide practical use.

(PhysOrg.com) -- Advanced imaging technology from the Brookhaven Labs and the European Synchrotron Radiation Facility (ESRF) in Grenoble has revealed an authentic Rembrandt self-portrait in an art authenticity effort involving leading art historians and scientists at the two labs. The hunt for authenticity all began when a private collector showed art historians in Amsterdam a small panel “Old Man with a Beard” from about 1630.

In a paper published Nov. 2 in Nature Communications, a team of researchers led by University of Maryland's Ichiro Takeuchi, in collaboration with Stanford Synchrotron Radiation Lightsource's Apurva Mehta, reported the discovery of large magnetostriction in an iron/cobalt alloy — in other words, the alloy shows a mechanical strain when a magnetic field is applied.

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully produced a first beam of X-ray laser light with a wavelength of 1.2 Angstroms.

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully produced a beam of X-ray laser light with a wavelength of 1.2 Angstroms, the shortest ever measured.

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have cut the ribbon on a new cutting-edge X-ray Free Electron Laser (XFEL) facility in Harima, the first such facility in Japan and only the second in the whole world. Nicknamed "SACLA" (SPring-8 Angstrom Compact Free Electron Laser), the new XFEL's intense beams will open a unique window onto the minuscule structure of molecules and rapid reaction of chemical species.

Emergency workers were scrambling at the troubled nuclear power plant in Japan after false radiation levels were initially reported. But, as Lucy Craft reports, the radiation levels are still far higher than normal.

By Gwyneth Dickey Zakaib One thing is certain about the human costs of the radiation leaking from the Fukushima Daiichi nuclear plant in Japan: they will pale in comparison to the catastrophic consequences of the March 11 earthquake and tsunami that triggered the crisis. [More]
