********************************************** 1. FINAL DAY TO SUBMIT PROPOSALS – TODAY The Call for Proposals is open for beamtime during the January-June, 2009 period. Users have the option of submitting a new proposal or submitting a Beam Time Request against an Active Proposal. Allocation of shifts for this period will be based on the highest ranked proposals (both new and active). New GENERAL USER PROPOSALS received for 01B1-1 (Mid IR), 02B1-1 (Far IR), 06ID-1 (HXMA), 11ID-1 (SGM) and 11ID-2 (PGM) beamlines will be reviewed for safety and technical feasibility, and scored for scientific merit by the CLS peer review committee, on completion of the call for proposal. Research time is assigned through this process twice per year. General User research should result in the publishing of scientific findings. For more information please visit our website: http://www.lightsource.ca/uso/call_proposals.php or contact our office at clsuo@lightsource.ca or 306-657-3700 2. BEAMLINE DEVELOPMENT UPDATE CMCF2: On September 3, beam (up to 20mA) was let into Sections #1 and #2 of the CMCF II (08B1-1) beamline for the first time. We were able to see the beam on the beam viewers in both Sections. This also means we started conditioning the elements overnight at 20mA. The Kohzu DCM was installed recently, which means all optical components are now installed, and we have begun conditioning of the M1 mirror. REIXS/SM has started conditioning the variable aperture and M1 mirrors. REIXS M1A/B mirrors saw first light from the storage ring. The REIXS EPU has been enabled. 10ID has been setup to deliver EPU light to both SM and REIXS beamlines. The RSXS scattering chamber was also delivered. Assembling of the RSXS and XES endstations are underway. QMSC: One of the first Phase III beamlines, the Quantum Materials Spectroscopy Center, has begun its Concept Design Report. Modeling of the beamline is underway and the designs of the EPUs are being considered. 3. SCIENCE HIGHLIGHT: LOCALIZING ORGANOMERCURY UPTAKE AND ACCUMULATION IN ZEBRAFISH LARVAE AT THE TISSUE AND CELLULAR LEVEL Using synchrotron x-ray fluorescence mapping, the authors examined the uptake and localization of organic mercury in zebrafish larvae. Strikingly, the greatest accumulation of methyl and ethyl mercury compounds was highly localized in the rapidly dividing lens epithelium, with lower levels going to the brain, optic nerve, and various other organs. The data suggest that the reported impairment of visual processes by mercury may arise not only from previously reported neurological effects, but also from direct effects on the ocular tissue. This novel approach is a powerful tool for directly investigating the molecular toxicology of heavy metals, and should be equally applicable to the study of a wide range of elements in developing embryos.

PNAS 105 (34), 12108-12112. DOI: 10.1073/pnas.0803147105 4. SUMMER SCHOOL SUCCESS The third annual CLS Summer School (S4III) was another huge success. Highlights included a poster session competition, the winner of which was Wijdan Malik from Laurentian University, who is currently working on his Masters in Chemistry with Graeme Spiers. The expert speakers included several CLS scientists, as well as John Neville (University of New Brunswick), Robert McKellar (NRC), Jesse Smith (U. Ottawa), TK Sham (UWO) and Bruce Ravel (NIST/APS). 5. NEW PEER REVIEW COMMITTEE MEMBER CLS welcomes Dr. Thomas Trainor, University of Alaska Fairbanks, as the newest member of our peer review committee. The PRC evaluates and scores General User proposals for the use of CLS experimental facilities emphasizing the excellence of science based on the quality of scientific research in the context of the field (merit); the suitability of CLS resources being allocated, relative to the proposed research (suitability); and the quality and capability of the researchers based on their track record (capability). Each proposal is reviewed on some level by members and in detail by two committee members and at least one external reviewer. Committee members serve a two-year term and the Chair serves a three-year term. Details on the Peer Review Committee are available at: http://www.lightsource.ca/uso/peer_reviews.php 6. NEW STAFF AND NOW HIRING – SCIENCE AND RESEARCH ASSOCIATES Adam Janis, Mechanical CAD Technologist, joins CLS again after taking some time off to travel around Europe. Welcome back Adam! Scott Irvine is our new QMSC Beamline Scientist. He just moved here from Goettingen Germany, where he was doing a postdoc in super resolution microscopy. Scott did his PhD at the University of Alberta on laser acceleration of electrons. Gay Oldhaver is our new Chief Development Officer. Gay’s mandate is to help us secure necessary funding for ongoing infrastructure development, from different sources. She has extensive experience in the development field, having worked at the University of Saskatchewan, the Heart and Stroke Foundation, and as a consultant. We are currently accepting applications for the following positions:
