Pioneering SESAME light source circulates first beam
Allan, Jordan, 12 January 2017. A beam circulated for the first time in the pioneering SESAME synchrotron at 18:12 (UTC+3) yesterday. The next step will be to store the beam.

Electron diffraction locates hydrogen atoms
Diffraction-based analytical methods are widely used in laboratories, but they struggle to study samples that are smaller than a micrometer in size. Researchers from the Laboratoire de cristallographie et sciences des matériaux (CNRS/Ensicaen/Unicaen), the Laboratoire catalyse et spectrochimie (CNRS/Ensicaen/Unicaen), and the Academy of Sciences of the Czech Republic have nevertheless been successful in using electron diffraction to reveal the structure of nanocrystals2. Their method is so sensitive that it has even located the position of hydrogen atoms for the first time, which is crucial in accessing the morphology of the molecules or the size of cavities in porous materials. This research, published on January 13, 2017, has made the front page of the journal Science.

Major step forward in theoretical description of two key properties of hot nuclei
In work published in Physical Review Letters, researchers from the RIKEN Nishina Center for Accelerator-Based Science and two universities in Vietnam—Duy Tan University and University of Khanh Hoa—have made a major breakthrough by proposing, for the first time, a unified and consistent microscopic approach capable of describing simultaneously two important quantities for understanding the statistical properties of nuclei—the nuclear level density and the emission probability of gamma-rays from hot nuclei—which play essential roles in stellar nucleosynthesis.

Stanford physicist suggests looking for dark matter in unusual places
For decades, particle physics has been the domain of massive colliders that whip particles around at high speeds and smash them into one another while teams of thousands observe the results. These kinds of experiments have produced great insights into forces and particles that make up the physical world.

Gamma rays will reach beyond the limits of light
Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits, and pave the way towards new fundamental studies.

The blob that ate the tokamak: Physicists gain understanding of bubbles at edge of plasmas
Scientists have completed new simulations that could provide insight into how blobs at the plasma edge behave. The simulations performed kinetic simulations of two different regions of the plasma edge simultaneously.
