********************************************** 1. 12th ANNUAL CLS USERS' MEETING - ONLINE REGISTRATION OPEN! The Canadian Light Source Annual Users' Meeting will be held in Saskatoon, on June 17-18, 2009. The meeting is a great opportunity to learn about the progress of the Canadian Light Source, present your recent synchrotron work and meet fellow users. Register online now, before the May 1st early registration deadline! This year’s meeting will feature a day of workshops on exciting new topics and scientific presentations including a beamline and facility update, latest results from the CLS, young scientists talks as well as a presentation from a high school Students on the Beamline group. Other events include a vendor exhibition, poster session, facility tour, and a banquet. You are invited to submit posters about your recent or planned synchrotron work. Submit your abstract before May 15: http://www.lightsource.ca/uac/meeting2009/abstract.php The Canadian Institute for Synchrotron Radiation will again offer a prize for the best synchrotron-related poster presented by a graduate student or post-doctoral fellow. The prize will be $1000 to support travel by the winner to attend a conference of their choice in the coming year and present their work. Funding is available to provide travel subsidies to students or post-docs attending the meeting plus attendees of the Annual Users' Meeting presenting a poster. Visit our website for program and registration information: http://www.lightsource.ca/uac/meeting2009 2. UAC CALL FOR NOMINATIONS The UAC is seeking nominations for both industrial and academic positions on the Users’ Advisory Committee. Please send the names of nominees to Helen Nichol, UAC chair (h.nichol@usask.ca) by June 19th. Nominees will be asked to submit a paragraph outlining his or her background in synchrotron science, as well as their vision for the UAC. 3. NEXT GENERATION X-RAY SOURCES WORKSHOP- MONTREAL, MAY 1, 2009 Around the world, several next generation X-ray sources are either under construction or being proposed. The Canadian Institute for Synchrotron Radiation (CISR) is hosting a workshop to inform the Canadian community about the status and the exciting new science being proposed to take advantage of these new sources. One goal of the workshop is finding out about the community in Canada interested in such projects. This workshop will highlight the energy recovery linacs (ERL), X-ray free electron lasers (XFEL), and laser induced X-ray sources. Topics will feature the science behind the new sources, source properties and the proposed new science they allow. The workshop will be held Friday, May 1, 2009 in the Rutherford Physics Building, McGill University, Montreal, Quebec. For further information, please visit http://www.physics.mcgill.ca/ngxs/ or contact Mark Sutton at mark@physics.mcgill.ca or phone: 514-398-6523. 4.

********************************************** 5. SCIENCE HIGHLIGHT: FERRITIN IS USED FOR IRON STORAGE IN BLOOM-FORMING MARINE PENNATE DIATOMS Primary productivity in 30–40% of the world's oceans is limited by availability of the micronutrient iron. Regions with chronically low iron concentrations are sporadically pulsed with new iron inputs by way of dust or lateral advection from continental margins. Addition of iron to surface waters in these areas induces massive phytoplankton blooms dominated primarily by pennate diatoms. Here we provide evidence that the bloom-forming pennate diatoms Pseudo-nitzschia and Fragilariopsis use the iron-concentrating protein, ferritin, to safely store iron. Ferritin has not been reported previously in any member of the Stramenopiles, a diverse eukaryotic lineage that includes unicellular algae, macroalgae and plant parasites. Phylogenetic analyses suggest that ferritin may have arisen in this small subset of diatoms through a lateral gene transfer. The crystal structure and functional assays of recombinant ferritin derived from Pseudo-nitzschia multiseries reveal a maxi-ferritin that exhibits ferroxidase activity and binds iron. The protein is predicted to be targeted to the chloroplast to control the distribution and storage of iron for proper functioning of the photosynthetic machinery. Abundance of Pseudo-nitzschia ferritin transcripts is regulated by iron nutritional status, and is closely tied to the loss and recovery of photosynthetic competence. Enhanced iron storage with ferritin allows the oceanic diatom Pseudo-nitzschia granii to undergo several more cell divisions in the absence of iron than the comparably sized, oceanic centric diatom Thalassiosira oceanica. Ferritin in pennate diatoms probably contributes to their success in chronically low-iron regions that receive intermittent iron inputs, and provides an explanation for the importance of these organisms in regulating oceanic CO2 over geological timescales.

SASKATOON SYNCHROTRON SUMMER SCHOOL IV - JUNE 13-18TH, 2009 Held in conjunction with the CLS Users’ Meeting, the fourth annual Saskatoon synchrotron summer school (S4IV), will include case studies and practical sessions designed for researchers specializing in Environmental Science to be able to utilize CLS synchrotron techniques. The users meeting, poster session, and associated workshops are included in fees. Case studies include:

CLS TO HOST INTERNATIONAL WORKSHOP – PCAPAC 2010 The Personal Computers and Particle Accelerator Controls (PCAPAC) Workshop occurs every two years and rotates between Asia, Europe and North America. PCAPAC 2010 will be hosted by the CLS in October 2010. PCAPAC originally concentrated on the use of lower cost personal computers for accelerator control and in recent years has expended to also include the use of PCs in beamlines and experimental end-stations as well as emerging technology such as FPGA and Web 2.0 technology. An EPICS collaboration meeting will be held jointly with PCAPAC. EPICS is widely used by many synchrotrons facilities including the CLS as well in other accelerator, astronomy and data acquisition applications. 8. NEW STAFF AND NOW HIRING Ward Wurtz, Jr. Accelerator Physicist, has bachelor degrees in Engineering Physics and Mathematics from the University of Saskatchewan. Ward is currently finishing a PhD in nuclear physics at the U of S. Welcome aboard Ward! Grant Bilbrough, Jr. Accelerator Physicist, has been working in the Boston area for the past three years, at an ion implant and source company. Grant was hoping to come home to Canada and the skills he has developed over the past few years in ion beams and sources was his ticket back to Saskatchewan. Welcome back Grant. We are currently accepting applications for the following positions:
