First scientific publication from data collected at NSLS-II
Just weeks after the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory, achieved first light, a team of scientists at the X-Ray Powder Diffraction (XPD) beamline tested a setup that yielded data on thermoelectric materials. The work was part of the commissioning activities for the XPD beamline, a process that fine-tunes the settings of beamline equipment to ready the facility for first scientific commissioning experiments in mid-March on its way to full user operations later in the year.

Scientists provide new data on the nature of dark matter
Recent research conducted by scientists from the University of Granada sheds light on the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.

Giant virus revealed in 3-D using X-ray laser
For the first time, researchers have produced a 3-D image revealing part of the inner structure of an intact, infectious virus, using a unique X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. The virus, called Mimivirus, is in a curious class of "giant viruses" discovered just over a decade ago.

Magnetic vortices in nanodisks reveal information
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Forschungszentrum Jülich (FZJ) together with a colleague at the French Centre National de la Recherche Scientifique (CNRS) in Strasbourg have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their method relies on measuring characteristic microwaves emanating from the vortices. The new knowledge about these signals could be used in the construction of extremely small components for novel memory technology or wireless data transmission. The results of the study appear in the current edition of the scientific journal Nature Communications.

Computer simulator will improve radiation therapy for cancer patients, experts say
A project to develop a computer simulator of dual foil scattering systems used in radiation therapy is underway. "The user user-friendly interface and real-time nature of the simulator also make it an effective educational tool for gaining a better understanding of the effects that various system parameters have on dose profiles," an author said. "In other words, it will help medical physicists and linear accelerator designers to better understand the physics behind the equipment with which they will be working."
