Profile of Bruce Alberts: the Education President PROFILE Profile of Bruce Alberts: The education president s Bruce Alberts steps down July 1 as one of the most accom- plished and distinguished presi- dents of the National Academy Aof Sciences (NAS), he is singularly fo- cused on education—specifically, teaching his students about real science. He has been brewing an idea for a new science course that he would like to teach to graduate students at the University of California, San Francisco (UCSF), the approach for which is partly inspired by the 3 years he spent in graduate school charging straight into an experimental dead-end. First, Alberts says, he would toss out the traditional classroom lectures and instead hand students a small stack of carefully selected scientific articles. Then he would have them argue among them- selves about which papers are outstanding and, most importantly, which are not. ‘‘We always talk about good papers, but we never talk about the substantial amount of mediocre work that’s done,’’ Bruce Alberts and children of staff of the Academy complex, National Academy of Sciences building, Alberts says.

OTA-BA-373 (Washington, DC: U.S. Government Printing Office, April 1988). Library of Congress Catalog Card Number 87-619898 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, DC 20402-9325 (order form can be found in the back of this report) Foreword For the past 2 years, scientific and technical journals in biology and medicine have extensively covered a debate about whether and how to determine the function and order of human genes on human chromosomes and when to determine the sequence of molecular building blocks that comprise DNA in those chromosomes. In 1987, these issues rose to become part of the public agenda. The debate involves science, technol- ogy, and politics. Congress is responsible for ‘(writing the rules” of what various Federal agencies do and for funding their work. This report surveys the points made so far in the debate, focusing on those that most directly influence the policy options facing the U.S. Congress, The House Committee on Energy and Commerce requested that OTA undertake the project. The House Committee on Science, Space, and Technology, the Senate Com- mittee on Labor and Human Resources, and the Senate Committee on Energy and Natu- ral Resources also asked OTA to address specific points of concern to them. Congres- sional interest focused on several issues: ● how to assess the rationales for conducting human genome projects, ● how to fund human genome projects (at what level and through which mech- anisms), ● how to coordinate the scientific and technical programs of the several Federal agencies and private interests already supporting various genome projects, and ● how to strike a balance regarding the impact of genome projects on international scientific cooperation and international economic competition in biotechnology.

  • The Gene Wars: Science, Politics, and the Human Genome
    8 Early Skirmishes | N A COMMENTARY introducing the March 7, 1986, issue of Science, I. Renato Dulbecco, a Nobel laureate and president of the Salk Institute, made the startling assertion that progress in the War on Cancer would be speedier if geneticists were to sequence the human genome.1 For most biologists, Dulbecco's Science article was their first encounter with the idea of sequencing the human genome, and it provoked discussions in the laboratories of universities and research centers throughout the world. Dul- becco was not known as a crusader or self-promoter—quite the opposite— and so his proposal attained credence it would have lacked coming from a less esteemed source. Like Sinsheimer, Dulbecco came to the idea from a penchant for thinking big. His first public airing of the idea came at a gala Kennedy Center event, a meeting organized by the Italian embassy in Washington, D.C., on Columbus Day, 1985.2 The meeting included a section on U.S.-Italian cooperation in science, and Dulbecco was invited to give a presentation as one of the most eminent Italian biologists, familiar with science in both the United States and Italy. He was preparing a review paper on the genetic approach to cancer, and he decided that the occasion called for grand ideas. In thinking through the recent past and future directions of cancer research, he decided it could be greatly enriched by a single bold stroke—sequencing the human genome. This Washington meeting marked the beginning of the Italian genome program.3 Dulbecco later made the sequencing

Oral History is a method of collecting historical information through tape-recorded interviews between a narrator with firsthand knowledge of historically significant events and a well-informed interviewer, with the goal of preserving substantive additions to the historical record. The tape recording is transcribed, lightly edited for continuity and clarity, and reviewed by the interviewee. The corrected manuscript is bound with photographs and illustrative materials and placed in The Bancroft Library at the University of California, Berkeley, and in other research collections for scholarly use. Because it is primary material, oral history is not intended to present the final, verified, or complete narrative of events. It is a spoken account, offered by the interviewee in response to questioning, and as such it is reflective, partisan, deeply involved, and irreplaceable. ********************************* All uses of this manuscript are covered by a legal agreement between The Regents of the University of California and Bruce Alberts on March 21, 2014.

  • Nucleosomal Barriers Can Accelerate Cohesin Mediated Loop Formation in Chromatin

All rights reserved. No reuse allowed without permission. The accidental ally: Nucleosomal barriers can accelerate cohesin mediated loop formation in chromatin Ajoy Maji1, Ranjith Padinhateeri2, Mithun K. Mitra1,*, 1 Department of Physics, IIT Bombay, Mumbai 400076, India 2 Department of Biosciences and Bioengineering, IIT Bombay, Mumbai 400076, India * [email protected] Abstract An important question in the context of the 3D organization of chromosomes is the mechanism of formation of large loops between distant base pairs. Recent experiments suggest that the formation of loops might be mediated by Loop Extrusion Factor proteins like cohesin. Experiments on cohesin have shown that cohesins walk diffusively on the DNA, and that nucleosomes act as obstacles to the diffusion, lowering the permeability and hence reducing the effective diffusion constant. An estimation of the times required to form the loops of typical sizes seen in Hi-C experiments using these low effective diffusion constants leads to times that are unphysically large. The puzzle then is the following, how does a cohesin molecule diffusing on the DNA backbone achieve speeds necessary to form the large loops seen in experiments? We propose a simple answer to this puzzle, and show that while at low densities, nucleosomes act as barriers to cohesin diffusion, beyond a certain concentration, they can reduce loop formation times due to a subtle interplay between the nucleosome size and the mean linker length.

  • Dear Student
    Dear Student: Welcome to Jefferson Medical College! From November through January of the first year, you will take the course Molecular and Cellular Basis of Medicine (MCBM), which contains topics from molecular biology, genetics, cell biology, cell physiology, and biochemistry. Courses in cell biology, genetics, or biochemistry are not a prerequisite for admission to Jefferson Medical College. MCBM is taught accordingly. However, we recognize that our course presents a special challenge to non-science majors, who sometimes find it challenging to learn the vocabulary and concepts, and to think in a scientific manner. If you are a non- science major and if you feel that you have a weak background in molecular biology and cell biology, we would like to recommend that you use a little bit of your time this summer to read about this material. This should help you get through November more comfortably. (Please note that this is not an across-the-board recommendation to study these topics. We make the following suggestions simply in response to students who struggled in the past and told us they wished they had known to study a little bit over the summer.) Following are comments from two students who finished the course in a previous year: One student wrote: "As a non-science major, just switching from anatomy, which is a fairly "verbal" science to biochem-style reading, diagrams, etc. was very difficult. I felt totally overwhelmed with the initial week's material on DNA, RNA, etc. as I simply felt totally unfamiliar with the "language." … “As I got more comfortable with reading scientific material, it all became easier, but initially it was very hard.
