An opportunity exists for partial funding to support scientific exchange visits between institutions within the EU and associated counties. The aim of the initiative is to encourage academic participation at synchrotron and FEL facilities and to help develop the careers of beamline scientists.
The IA-SFS (Integrating Activity on Synchrotron and Free Electron
Laser Science) project administers the programme in this area and further
details, including an application web form, can be found at the IA-SFS website:

If you have any questions not answered by the website please let me know.

4GLS User MeetingThe purpose of the meeting is to inform and consult with, potential
users on the design of 4GLS, following the recent publication of the Conceptual
Design Report.
A number of international experts will give presentations describing the key
science that will be achieved.
Discussion sessions will ensure the the evolving aspirations of the user community
continue to be met as the detailed design parameters are confirmed.

SRS Station 9.5 HPT has been developed over the past year to provide a dedicated station for high pressure powder diffraction. The high pressure is generated by compressing a sample between two diamonds (the so-called diamond anvil cell). X-rays pass through the first diamond anvil, are diffracted by the sample, then pass through the second diamond to be collected using an image plate from which the intensity and diffraction angle are measured. An 80-fold increase in incident X-ray flux was achieved last year using a focusing monochromator developed in-house at Daresbury Laboratory by David Laundy. Now, a mar345 in-line image plate X-ray detector has been installed by Alistair Lennie (Station Scientist, Station 9.5 HPT), and within days has contributed to the discovery of a new high pressure phase.
Having increasing the incident flux, it was the data readout rather than data collection that was the rate limiting step, but because the mar345 detector speeds up data read-out by a factor of 20, the time taken for these two fundamental steps are now well matched. Combined with the increase in X-ray flux, rapid screening of sample structures is made possible by quickly collecting and analysing powder diffraction data after changes in pressure and/or temperature have been made. Diffraction patterns can be collected with exposures of less than two minutes, and reading the image now takes only 90 seconds. Integration of the powder pattern allows full use of all of the data collected.
Just days after the new detector was installed, researchers have taken advantage of these developments by screening structures of selected compounds crystallised under high pressure while contained within diamond anvil cells. This demonstrates how the rapid turnaround resulting from both enhanced X-ray flux and rapid data readout is expected to contribute to the characterisation of known and novel high-pressure phases.
The images show the mar345 camera located on Station 9.5 HPT, and the diffraction pattern of a sample contained in a diamond anvil cell. (click on the image to view larger version)

Molecular Biophysics Group make Front CoverIn a recent JMB paper (March 10th 2006, vol 356, 1152-1162) , we present data that support the possibility that in a cellular environment with low availability of free copper, Zn-Zn may be the preferred metallation state of SOD1 prior to its interaction with the copper chaperone. We obtained atomic resolution crystal structures (the highest is 1.07 Å, obtained using BL10.1) and biophysical data for human SOD1 in three metallation states: Zn-Zn, Cu-Zn and `as-isolated’. These data represent the first atomic resolution structures for human SOD1, the first structure of a reduced SOD1, and the first structure of a fully Zn-substituted SOD1 enzyme. The Zn-Zn SOD1 dimer appears to be as stable as the native Cu-Zn protein and would avoid problems associated with aggregation of apo-enzyme.
Human Cu-Zn superoxide dismutase (SOD1) protects cells from the effects of oxidative stress. Single point mutations of SOD1 are linked to the familial form of motor neuron disease, a fatal progressive neurodegenerative disorder for which there is currently no cure. Several hypotheses for SOD1 mutant toxicity involve the mis-metallation of the enzyme and our previous work has shown that amyloid-like filaments can be formed from metal depleted wild-type protein (J. Mol. Biol. 328, 887-891 2003).

SAXIER is an initiative of Europe’s main small angle X-ray scattering (SAXS) laboratories based at synchrotrons to explore novel scientific applications for the new generation of SAXS beamlines. The project is coordinated by the EMBL Hamburg Outstation as a Design Study under the Infrastructure programme of the EU Framework Programme 6 (FP6). The kick-off meeting consisted of reports from the five partner institutes involved in eight work packages. Also the EU project officer for this project gave advice and guidance in specific issues and provided insights into the changes between FP6 and the proposed FP7. A workshop for the dissemination of work done by the SAXIER consortium will be organized as a satellite meeting to the next ESRF User meeting in February 2007.
Partners of the SAXIER consortium gathered for the kick-off meeting at the EMBL Outstation in Hamburg on 30th January 2006.SAXIER people (right to left): Dimitri Svergun (EMBL Hamburg, co-ordinator), Manfred Roessle (EMBL Hamburg), Margret Fischer (EMBL Hamburg, project secretary), Oleg Konovalov (ESRF), Christian Riekel (ESRF), Maria Douka (EU project officer), Günter Grossmann (DL), Javier Perez (Soleil), Maxim Petoukhov (EMBL Hamburg), Heinz Amenitsch (IBR), Peter Laggner (IBR) and Samar Hasnain (DL)

Konstantinos Paraskevopoulos recently completed his Ph.D. viva at Liverpool John Moores University (LJMU).This is Professor Samar Hasnain's first PhD student from LJMU. Previous PhD students were registered at De Montfort University, Leicester. Professor Michael Brown, vice chancellor of Liverpool John Moore's University marked the occasion by congratulating Konstantinos Paraskevopoulos personally.
Dr. Konstantinos Paraskevopoulos begins his post doctoral career from March 2006 when he joins EMBL in Hamburg.
