DOE/SC-0147 Applications of New DOE National User Facilities in Biology Workshop Report Published: February 24, 2012 U.S. Department of Energy Office of Science Office of Biological and Environmental Research i ii U.S. Department of Energy Office of Science • Office of Biological and Environmental Research PREFACE his report represents the discussions and findings of a workshop held in May 2011 to consider the significance for biological science of five major Department of Energy DOE( ) national user facilities that either have recently begun full operations (Linac Coherent Light Source and Spallation Neutron Source), are under construction T(National Synchrotron Light Source-II), or are being designed (Advanced Photon Source Upgrade and Next Generation Light Source). The Office of Biological and Environmental Research (BER), a program office in DOE’s Office of Science, initiated support for researcher access to major user facilities for structural biology in 1990, when DOE was engaged in a similar program for constructing and upgrading these facilities. That initiative was focused on DOE synchrotron light sources and neutron beam facilities. The workshop took place May 9–11 in Rockville, Maryland. Two months before the meeting, leaders from each of the five facilities submitted papers describing the facilities and potential applications in biology (these papers are included in Appendices A–E of this report). A panel of experts in the design, operation, and management of these facilities, as well as in several key nonfacility technologies used in biological research and in major areas of biology supported by BER, read these reports prior to the meeting (see Appendix F for participants list). At the meeting, the entire panel separately heard presentations from and engaged in discussions with representatives of each facility and then developed outlines for the chapters of this report. The Executive Summary and the five chapters were prepared after the meeting by panel members and circulated to the entire panel for comments and editing prior to completion of the report. BER appreciates the involvement of all panel members, especially the co-chairs, Dagmar Ringe of Brandeis University and David Eisenberg of the University of California–Los Angeles. The appendices describing the five facilities were prepared by staff of the respective national laboratories. In some cases, comments from panel members led to revisions of a paper; however, the final version included in this report represents the views of the national laboratory, not the panel members. The efforts of national laboratory staff members to prepare their papers are very much appreciated. All of the written materials in this report were edited and prepared for publication by members of the Biological and Environmental Research Information System group at Oak Ridge National Laboratory. BER is indebted to the members of this group who devoted extensive time and much thought to preparation of all report components for publication. Comments on this report will be welcomed by Roland Hirsch and Susan Gregurick, the BER program managers involved in the workshop.

    Perché chiamiamo “fondamentale” la Cenerentola della ricerca? (di M. Brunori) Neanche nel Pnrr si trovano speranze di cambiamento e iniziative coraggiose per la ricerca di base. Ma nelle scienze della vita non sono rare le scoperte nate da progetti di ricerca curiosity driven che richiedono tempo per portare risultati Soci dell'Accademia dei Lincei. (a cura di Maurizio Brunori, Prof. emerito di Chimica e Biochimica, Sapienza Università di Roma, Presidente emerito della Classe di Scienze FMN dell’Accademia dei Lincei) Nelle scienze della vita non sono infrequenti le scoperte innovative nate da progetti di ricerca di base, iniziati per cercare di comprendere qualche importante proprietà di un essere vivente, misteriosa ma ovviamente necessaria se è stata conservata nel corso dell’evoluzione. Questi progetti sono quelli che si iniziano per curiosità intellettuale, ma richiedono libertà di iniziativa, impegno pluriennale e molto coraggio in quanto di difficile soluzione. Un successo straordinario noto a molti è quello ottenuto dieci anni fa da due straordinarie ricercatrici, Emmanuelle Charpentier e Jennifer Doudna; che a dicembre hanno ricevuto dal Re di Svezia il Premio Nobel per la Chimica con la seguente motivazione: “for the development of a new method for genome editing”. Nel 2018 in occasione di una conferenza magistrale che la Charpentier tenne presso l’Accademia Nazionale dei Lincei, avevo pubblicato sul Blog di HuffPost un pezzo per commentare l’importanza della scoperta di CRISPR/Cas9, un kit molecolare taglia-e-cuci che consente di modificare con precisione ed efficacia senza precedenti il genoma di qualsiasi essere vivente: batteri, piante, animali, compreso l’uomo.

  • High Resolution Spectroscopy with the Neutron Resonance Spin Echo Method
    High Resolution Spectroscopy with the Neutron Resonance Spin Echo Method vorgelegt von Diplom-Physiker Felix Groitl aus Erlangen von der Fakultät II - Mathematik und Naturwissenschaften der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktor der Naturwissenschaften Dr. rer. nat. genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. M. Kneissl Gutachter: Prof. Dr. D. A. Tennant Gutachter: Prof. Dr. P. Böni Gutachter: Dr. K. Habicht Tag der wissenschaftlichen Aussprache: 18.12.2012 Berlin 2013 D 83 Abstract The first part of this thesis is dedicated to explore new territory for high resolution Neu- tron Resonance Spin Echo (NRSE) spectroscopy beyond measuring lifetimes of elementary excitations. The data analysis of such experiments requires a detailed model for the echo amplitude as a function of correlation time. The model also offers guidance for planning NRSE experiments in terms of a sensible choice of parameters and allows predicting quan- titatively the information content of NRSE spectroscopy for line shape analysis or energy level separation. Major generalizations of the existing formalism, developed in this thesis, allow for violated spin echo conditions, arbitrary local gradient components of the dispersion surface and detuned parameters of the background triple axis spectrometer (TAS) giving rise to important additional depolarizing effects, which have been neglected before. Fur- thermore, the formalism can now be applied to any crystal symmetry class. The model was successfully tested by experiments on phonons in a high quality single crystal of Pb and the results demonstrate the stringent necessity to consider second order depolarization effects. The formalism was subsequently extended to analyze mode doublets. As a major step for- ward, detuning effects for both modes are taken into account here.

The LCLS, with proposed construction in the 2003-2006 time frame, has been designed to utilize the last third of the existing Stanford Linear Accelerator Center (SLAC) linac. The linac produces a high-current 5- 15 GeV electron beam that is bunched into 230 fs slices with a 120 Hz repetition rate. When traveling through a sufficiently long (of order of 100 m) undulator, the electron bunches will lead to self amplification of the emitted x-ray intensity constituting an x-ray free electron laser (XFEL). If funded as proposed, the LCLS will be the first XFEL in the world, operating in the 800-8,000 eV energy range. The emitted coherent x-rays will have unprecedented brightness with 1012-1013 photons/pulse in a 0.2-0.4% energy bandpass and an unprecedented time structure with a design pulse length of 230 fs. Studies are under way to reduce the pulse length to tens of femtoseconds. This document presents descriptions of the early scientific experiments selected by SAC in the spring of 2000.

  • 2017 Nobel Prize in Chemistry Awarded to Prof. Joachim Frank
    2017 Nobel Prize in Chemistry Awarded to Prof. Joachim Frank October 4, 2017 Columbia University congratulates Joachim Frank, PhD, professor of biochemistry and molecular biophysics and of biological sciences, a winner of the Nobel Prize in Chemistry 2017, shared with Richard Henderson and Jacques Dubochet “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution.” Joachim Frank's Bio Joachim Frank, PhD, is a professor of biochemistry and molecular biophysics at Columbia University Medical Center and biological sciences at Columbia University. Dr. Frank helped pioneer the development of cryo-electron microscopy, a technique used to reveal the structures of large organic molecules at high resolution. Dr. Frank developed the necessary computational methods for reconstructing the three- dimensional shape of biological molecules from thousands of two-dimensional images of molecules, methods employed today by most structural biologists who use electron microscopy. Cryo-electron microscopy is commonly used by structural biologists to study the molecular processes inside cells that drives protein synthesis. Using this technique, Dr. Frank has made important discoveries about the interactions between ribosomes (complex molecules that serve as the ‘factories’ of the cell) and other proteins in the cell. In a 2013 paper in Nature, Dr. Frank uncovered unique details about ribosomes from the parasite that causes African sleeping sickness that could lead to the development of new drugs for this disease. In another Nature paper later that year, he revealed how viral RNA commandeers the ribosome of the virus’s host to produce new viruses. Dr. Frank was born in Germany during World War II.
