Prof John Helliwell joins Structural Dynamics Editorial Advisory Board
Congratulations to John Helliwell, recipient of the 2014 ACA Patterson Award
Structural Dynamics welcomes John Helliwell in its Editorial Advisory Board. John R. Helliwell (University of Manchester, UK) has been selected to receive the 2014 ACA Patterson Award for his pioneering contributions to the development of the instrumentation, methods and applications of synchrotron radiation in macromolecular crystallography. A longtime member of ACA and Professor of Structural Chemistry at the University of Manchester, UK, his career is dedicated to exploring new applications of synchrotron radiation and he has worked tirelessly to improve synchrotron and neutron facilities worldwide. Always driven by the desire to innovate and overcome existing limits, John expanded the use of anomalous dispersion techniques to explore new challenges in structural biology. He contributed to solving the phase problem by, among other things, introducing longer wavelength radiation to expand anomalous scattering applications for phasing to a wider range of scatterers. He is also recognized for having pushed forward the development of Laue methods for time-resolved studies and other applications, both in x-ray and neutron crystallography.
The truly innovative nature of his work is demonstrated by the large number of "firsts" encountered in a synopsis of his career. He led the design and realization of the first dedicated synchrotron radiation x-ray source (SRS) instrument for protein crystallography (1981) and of the first protein crystallography synchrotron radiation wiggler instrument (1984).
With US scientists, notable initiatives were in longer wavelength anomalous dispersion (Howard Einspahr), weakly scattering crystals (Steve Ealick), microcrystal diffraction (Britt Hedman and Keith Hodgson), virus crystal diffraction (Michael Rossman) and Laue diffraction (Keith Moffat). His work at SRS-Daresbury was highlighted in Scientific American. In the late 80s and into the 90s, he led the European working group for macromolecular crystallography for the ESRF Foundation Phase report and became Vice Chair and then Chair of the ESRF Science Advisory Committee.
From 1979 to 1999 he developed two-wavelength anomalous-dispersion phasing techniques using synchrotron radiation, particularly important for their applications in radiation sensitive cases. In 1995 he first demonstrated sharpened crystal mosaicity in microgravity grown protein crystals and in 1998 he conducted one of the first time-resolved Laue protein crystallography studies harnessing fast readout CCD detectors. In 2001-2002 he determined the first de novo structure of apocrustacyanin A1, solved with softer x-rays. In 2005 he initiated ab initio structure determination by MAD phasing of powder diffraction data and discussed the potential for extending the method to structures of large molecules containing anomalous scatterers.
He is the author of a classic book on protein crystallography Macromolecular Crystallography with Synchrotron Radiation, published by Cambridge Univ. Press in 1992 (available in paperback since 2005). He is a founding editor of the Journal of Synchrotron Radiation and was president of the European Crystallographic Association (2006 - 2009). He served as Editor-in-Chief of the IUCr journals (1996 - 2005) during which period Acta Crystallographica Section E and Section F were launched.

Structural Dynamics welcomes Ahmed Zewail to join the Editorial Advisory Board. Ahmed Zewail is the Linus Pauling Chair professor of chemistry and physics, and director of the Center for Physical Biology at Caltech. He is the sole recipient of the 1999 Nobel Prize in Chemistry, and his other honors include fifty Honorary Degrees, orders of merits, postage stamps and more than hundred international awards. Dr. Zewail has published some 500 articles and 10 books and is known for his effective public lectures and writings. For his leadership role in world peace, he received the “Top American Leaders Award” from The Washington Post and Harvard University. In 2009, President Barack Obama appointed him to the Council of Advisors on Science and Technology, and in the same year he was named the first U.S. Science Envoy to the Middle East. In 2011, the Egyptian government established “Zewail City of Science and Technology” as the national project for scientific renaissance.
