3. Science Highlight: Understanding quinoa at the genetic level

A team of researchers from the University of Guelph and the CLS Synchrotron is using a combination of nanoscale imaging techniques to show both chemical and structural information about individual quinoa chromosomes at an extremely fine level of detail. The results were recently published in Nanoscale Research Letters.

4. News Release: Seeing a solution to cleaner oil

Scientists from the CLS and Alberta Innovates Technology Futures have embarked on a research project that is changing what we know about oil recovery and could result in more environmentally efficient methods of getting oil.

Several important factors involved in the process of oil recovery were observed – oil, sand and water specifically. Through a unique live imaging experiment at the CLS, scientists were able to see how the three materials interacted with one another in a dynamic way. As most processes for heavy oil are more complicated and involve the addition of solvents, steam, and other things, scientists were hoping a simpler recovery process is possible.

5. Science Highlight: Perennially and annually frozen soil carbon differ in their susceptibility to decomposition: Analysis of Subarctic earth hummocks by bioassay, Xanes and pyrolysis

Earth hummocks are the most common patterned ground feature in the Subarctic region and subduction of organic matter by cryoturbation (i.e., mixing of soil layers by repeated freezing–thawing) physically protects soil organic carbon (SOC) from decomposition. Climate models predict that Subarctic regions will experience disproportionate rates of warming, which may accelerate rates of decomposition of stored SOC and thus cause increased release of CO2. Our objectives in this study were to characterize and develop relationships between the chemistry and bioavailability of SOC in the horizons of Subarctic earth hummocks. Biodegradability was assessed in a controlled mineralization study in the laboratory. The chemical composition of soil organic matter (SOM) was characterized by X-ray absorption near-edge structure (XANES) spectroscopy at the carbon (C) K-edge and its thermal stability was determined by Rock-Eval pyrolysis.

Horizon classification is in accordance with the Canadian System of Soil Classification (Soil Classification Working Group, 1998). Horizons with ‘y’ suffix are affected by cryoturbation and those with ‘z’ suffix are permanently frozen.

7. Mx Data Collection School: June 9-13

The Canadian Macromolecular Crystallography Facility is pleased to announce the 4th Annual CLS Mx Data Collection School, being held at the CLS June 9 – 13. This is an intensive hands-on data collection school intended to equip participants to effectively collect macromolecular crystal diffraction data both at the synchrotron and remotely.

This year's special topic will include the molecular replacement method, making effective use of COOT and structure validation, with invited speaker Dr. Trevor Moraes (U. of Toronto). Given enough interest, an optional introductory crystallography review will be offered on Sunday June 8. Attendance is limited so early application is encouraged.

Application deadline is April 11. Visit the school website at cmcf.lightsource.ca/school for more information and to apply.

Contact Dr. Pawel Grochulski pawel.grochulski@lightsource.ca for more information.

9. Applications of Synchrotron Imaging for Crop Improvement: June 10-12

The Application of Synchrotron Imaging for Crop Improvement Workshop will explore the application of synchrotron light for imaging plants, which will support the selection and development of superior crop lines.

The workshop will look at ways plants can be structurally and functionally imaged, in-vivo to in-situ, and applying this information to aid in the development and selection of higher yielding crop varieties. It will also focus on imaging all components of the plant, from root to stem. It is believed that imaging will be a key tool in achieving the substantial increases in crop productivity to feed the world’s growing population.

Join researchers and industry partners for presentations, exhibitor booths, a poster session, networking events and a tour of the CLS. You will have opportunities to meet some of the world’s leading innovators in this industry, in both research and commercialization.

10. Spectromicroscopy beamline upgrade passes a major milestone

The detailed design of a new cryo-cooled scanning transmission X-ray microscope (STXM) was completed on Feb. 12. It is a component of a CFI Leading Edge fund project, "Enhancing the Spectromicroscopy Beamline and Endstations at the Canadian Light Source” (U of S; S.G. Urquhart, Project Leader), with support from the AFCC Automotive Fuel Cell Cooperation Corp. This microscope will allow CLS users to study a wider range of materials, especially biological, medical and other soft matter through spectromicroscopy and spectro-tomography techniques on cryogenically cooled samples.

The core design team consists of Kyle Epp, Darwin Taylor, Adam Leontowich, Chris Regier, Russ Berg, John Swirsky, Chithra Karunakaran, Adam Hitchcock (McMaster) and Stephen Urquhart (U of S). External reviewers Tolek Tyliszczak (ALS) and Chris Jacobsen (Northwestern U/APS) and many other CLS staff also made significant contributions to the design.

The procurement and assembly phase is now underway, and installation in the SM hutch is expected this summer.



11. Canadian Synchrotron Summer School (CS³): July 20-25

The Canadian Synchrotron Summer School (CS³) will focus on providing theory and practical experience for researchers interested in improving their imaging capabilities. This school will provide background theory and practical experience from proposal writing to sample prep through data collection, reconstruction and visualization. We invite scientists who have some experience with synchrotron based imaging to apply. Participation is limited at 20 to ensure everyone is able to gain hands-on experience. The deadline for early application is May 15th. If you are accepted, payment of the registration fee ($500 + GST, $350 + GST for students) is required to hold your spot.
