New Light Always Creates New Science & Technology 16 June 2010 The 4th Yamada Conference on Advanced Photons and Science Evolution 2010
Synchrotron Radiation (SR) Synchrotron radiation is electromagnetic radiation generated by a synchrotron. It is similar to cyclotron radiation, but generated by the acceleration of ultrarelativistic (i.e., moving near the speed of light) charged particles through magnetic fields. This may be achieved artificially in synchrotrons or storage rings, or naturally by fast electrons moving through magnetic fields in space. The radiation produced may range over the entire electromagnetic spectrum, from radio waves to infrared light, visible light, ultraviolet light, X-rays, and gamma rays. It is distinguished by its characteristic polarization and spectrum.

Structure of Rhodopsin, a G Protein-Coupled Receptor ◆ G Protein-coupled receptors (GPCRs) play a role of switch to control the operation and fate of cells as receptors for a variety of hormones and neurotransmitters. ◆ Many kinds of drugs targeting GPCRs such as antasthmatic and psychotropic have been developed. ◆ Rhodopsin, one of GPCRs, is a membrane protein in retina of eye, and acts as a very sensitive molecular switch. ◆The structure of bovine rhodopsin was determined using RIKEN Structural Biology I beamline (BL45XU). ◆ The findings from the structural analysis of rhodopsin elucidated a variety of visual functions of rhodopsin. ◆ This achievement was published in Science on 4 August 2000, and the image of rhodopsin has adorned the cover. ◆The number of citing articles is 2746, current as of May 14, 2010.
