ASCB Newsletter - October 2000

Society Partners with Celebrity Advocates for Stem Cell Research

ASCB President Richard Hynes was the lead witness in support of federal funding of stem cell research at a recent Senate hear- ing called by Senator Arlen Specter (R-PA) following the release of the NIH guidelines on funding stem cell research.

Hynes noted that opponents have claimed that embryonic stem cell research is “’illegal, unnecessary and immoral.’ We respectfully disagree on all counts,” he said. Hynes went on to argue that all promising “forms of stem cell research—embryonic, fetal and adult—should be pursued vigorously.”

Testifying with Hynes in support of stem cell research were actors Mary Tyler Moore and Michael J. Fox. Each delivered compelling testimony urging Congress to invest in any research which could lead to the prevention or cure of diabetes, Parkinson’s and other crippling diseases.


Young UK Cell Biologist Named

Matthew Howard, a graduate student in the laboratory of Clare Isacke in the Department of Biology at Imperial College of London, was named by the British Society for Cell Biology “Young Cell Biologist of the Year 2000.” Howard will participate in the 40th ASCB Annual Meeting by presenting his poster on A Novel Endocytic Receptor with a Role in ECM Remodelling.


International Affairs Chair Appointed

Enrique RodriguezBoulan of Cornell University Medical College was appointed Chair of the ASCB International Affairs Committee by President-elect Elaine Fuchs.

Rodriquez-Boulan, a native of Argentina, will succeed current Chair Kai Simons on January 1. A major interest of RodriquezBoulan is to work with the Committee to support cell biology in South America.


Goodenough to Chair Nominating Committee

Ursula Goodenough of Washington University will serve as 2001 Chair of the ASCB Nominating Committee. She was appointed by Society President-elect Elaine Fuchs.

Goodenough, who served as Society President in 1995, will appoint a committee to be charged with identifying and recruiting candidates to serve as Society officers in 2002.


An Interview with Keith Yamamoto

How to Use Electronic Publishing to Enhance Your Science
Molecular Biology of the Cell Editor and UCSF Cellular and Molecular Pharmacology Chair Keith Yamamoto was recently interviewed by the ASCB Newsletter about electronic publishing and how authors can take best advantage of publishing technologies to enhance the presentation of their science.

NL: Increasingly, journals are encouraging or requiring authors to put more and more of their content on the Web, and not in the printed version. This sounds like a business strategy by which publishers can save paper, printing and mailing costs. Why should scientists concern themselves with this?

KRY: If scientists allow decisions about the configuration of electronic publishing to be driven by economic considerations, we shall have abrogated an important responsibility and missed a great opportunity. First, we need to remind ourselves that communication of our findings is a crucial part of doing science—that we should regard publishing as part of the scientific process. Thus, just as working scientists make all decisions about the content of journals such as MBC, scientists should determine how the Web will be used to present their findings. Second, the Web, in combination with print, offers new ways to communicate science —in this sense, the Web could be viewed as a technological advance that can enhance our science in much the same way as a new lab procedure.

NL: You mention “the Web, in combination with print”. Will both media persist, and how might their content differ?

KRY: At least for now, both media will persist, but they may be increasingly distinct in purpose; that is, they may represent different “layers” of scientific communication. Today, perhaps for reasons that are driven partly by economics, some journals present little more than expanded abstracts, with little attention to methodological description, presentation of control experiments, or a thoughtful consideration of the findings. Electronic publishing offers the potential for authors to convey their full story, and to describe their studies in sufficient detail that they can be reproduced. This alone would facilitate the process of science. By this view, the print version of a paper would be accessible for general readers, and would also serve as a “road map” to the web version.

NL: As an example, what might be published electronically that would not appear on paper?

KRY: Materials and Methods is a simple but important example. Originally, publication standards required full descriptions. However, while the details are vitally important to specialists in the field, they are not of great interest to general readers. Hence, perhaps the print version should include only enough methodological description to maintain accessibility for general readers, while the Web version would include all the details. Indeed, we shall likely institute this policy soon in MBC.

NL: This sounds like good advice to marginally improve the dissemination of science. Are there opportunities to take advantage of electronic publishing for more dramatic contributions to the presentation of research?

KRY: Absolutely. In fact, Molecular Biology of the Cell was the pioneer among life science journals in offering the publication of peer-reviewed video content and large datasets. These are elements that simply cannot be published on paper. They are now becoming common if not standard features in life science journals, together with the capabilities for cross-referencing, linking to other articles, broad searches, transmission of alerts and so forth, that are so well suited to the Web.

NL: You indicated that the print and Web versions of a paper represent different layers of information. Besides Materials and Methods, what else might distinguish these layers?

KRY: The Web of course is an ideal vehicle for presenting information in a multilayered fashion. A wellconstructed article would allow readers to “enter” at their own selected levels of expertise and interest, and to navigate freely from there. Here’s a nice example of layering from the print format: Science magazine uses “Notes,” in which a comment, caveat, provocative detail, or side issue that might well be interesting, but would interrupt the flow of the narrative, can be relegated to a note in the References and Notes list. Everyone who writes papers encounters the opportunity to include such points, but at present most often exclude them on the basis of word limits, interruption of flow of the main point, or lack of a format (except in Science) for citing this information as a sidebar to the article. Such sidebars could readily be presented in their own layer on the Web, in considerable detail and length if appropriate. These could add considerably to the scope, range and interest level of an article.

NL: Would citations differ between Web and paper?

KRY: Faced with space limitations, authors are hard-pressed to cite primary references on paper. And with the explosion of review journals, reference lists in research articles are threatening to become little more than brief compendia of recent minireviews. This erosion of scholarliness and historical perspective in our field makes it increasingly difficult for students (and experienced investigators, for that matter) to discern the origin, evolution and progression of ideas and discoveries. I’m not saying that we all have to cite Mendel and Darwin in every paper we write, but a small nod to how we got here is important. Hence, I would like to see journals require citation of relevant primary literature, including key initial discoveries and key subsequent advances, in their Web versions, while the print versions could maintain general accessibility with an appropriate mix of citations to reviews and to primary literature.

NL: So, generally, how can publishing electronically advantage authors and readers?

KRY: Electronic publishing represents an opportunity to change the way we write and read papers and to add value to the publication process. The reader can control the level of expertise and depth; authors, by organizing their work differently, can include the desired amount of content without conflicting with the reviewer’s obligation to eliminate “sidebar” content for clarity and to satisfy the space constraints of paper. In the bargain, authors will be able to appeal to general readers while also satisfying the needs of specialists.

NL: As you know, much controversy surrounds Pub Med Central, the project launched by the National Library of Medicine under Harold Varmus’ NIH directorship, to make life science journal content freely available on the Web. Publishers are crying foul because they fear that they will lose subscription income if their content becomes available without charge. Many publishers—both Society-based and commercial—claim that if successful, PMC will shut them down. What do you think?

KRY: Electronic publishing is here to stay, to the benefit of all scientists and the community at large. And despite the predictions of those who are fearful of PMC, I believe that paper publication will also be with us for a good long time. The challenge is to find a business model that encourages publishers to provide quality review and publication while also opening electronic access to content. Most or all of the current PMC journals have adopted a scheme in which they provide their journal’s content to PMC after a short delay—from days to months—allowing the publisher to capture revenue from those willing to pay a premium for prompt delivery of content. Of course, publishers also provide the traditional paper journal to individuals and institutions, which PMC has no intention of doing. For its part, PMC can offer not only broad access, but also archival content, which is not cost-effective for individual publishers. This will be enormously valuable to the scientific community. So while we don’t yet know how the final picture will look, it appears that there is room in the scientific-publishing marketplace for publishers to continue to publish while also expanding the scope of their service to the community by participating in PMC.

NL: How could Molecular Biology of the Cell justify jumping into electronic publishing and participating in PMC before these issues have played out?

KRY: MBC was founded on the notion that the publication of scientific experiments is an extension of the experiments themselves, and that scientists should therefore govern that process. If we don’t communicate information in the most innovative and effective ways, we’re not doing the experiments right.

WWW.Cell Biology Education

The ASCB Education Committee calls attention each month to Web sites of educational interest to the cell biology community. The Committee does not endorse nor guarantee the accuracy of the information at any of the listed sites. If you wish to comment on the selections or suggest future inclusions please send a message to Robert Blystone.

  1. Molecular Expressions: Images from the Microscope
    The National High Magnetic Field Laboratory has an extensive educational outreach program. The lab operates from Florida State University and is supported by the National Science Foundation, Los Alamos Laboratory, and the State of Florida. One may reach its main educational outreach URL at http://k12.magnet.fsu.edu>. The Molecular Expressions project is the focus of this review. The purpose of the site is expressed in its first paragraph: “We are going where no microscope has gone before by offering one of the Web’s largest collections of color photographs taken through an optical microscope (commonly referred to as ‘photo-micro-graphs’). Visit our Photo Gallery for an introductory selection of images covering just about everything from beer and ice cream to integrated circuits and ceramic superconductors. These photographs are available for licensing to commercial, private, and non-profit institutions, or for personal use on the Web.” This site is simply amazing; thanks to Education Committee member Bob Bloodgood for pointing it out. Be prepared to spend a very long time here; this is a complete educational site. You will need the latest browsers, Java version, Flash player, and T-internet connection speed to take advantage of all that is available at this site.

    The initial page currently gives over 50 choices of things to do at the site. Each choice is better than the last. It begins with a fluorescence microscopy digital image gallery. Beautiful images of dog tick, bird lung, fava bean root tip mitosis, house fly face, compact bone, and obelia hydroid are but a few of the possible selections. Teachers looking for biological images will find this to be a goldmine. The next choice is a tutorial on image formation. Using java scripts one can explore numerical aperture and image resolution and then move on to interactive conoscopic imaging of periodic gratings. The next choice moves into a subject called pond life. One can obtain movies of topics such as amoebae phagocytosis; another goldmine for a teacher looking for excellent time lapse movies to demonstrate biological phenomena. Some of the clips were difficult to download; specific compression software is necessary to open several of the movies. There is a selection that allows stereoscopic zoom microscopy in real time through a virtual microscope. Another choice provides clear explanations of digital imaging cameras and technology. A “Museum of Microscopy” follows the history of microscopy through pictures of instruments. One can even obtain a Windows-based screen saver image file with up to 80 images of historical microscopes. Another location has a Power of Ten animation. Photomicrography is covered thoroughly including discussions and demonstrations of color temperature, filters, and film basics. A whole course of information resides in this part of the Web site. Of course, there are the image galleries. All those gee whiz type photomicrographs are here. There are pictures of black grape rot, amino acids, beer, dinosaur bones, DNA, moon rocks, neurotransmitters, soft drinks, andwine. This is a fascinating site that provides endless educational possibilities. It is a real treasure.

  2. BioLogica
    The first page of this URL states as it purpose: “BioLogica enables students to manipulate processes at different, but dynamically related levels of life function ... that embody increasingly elaborate models of cellular and molecular processes.² BioLogica is being developed by The Concord Consortium (http://www.concord.org) with National Science Foundation funding. The main Concord site describes a large array of activities of which BioLogica is one. The BioLogica site uses a “Web Lab” metaphor and has two Java-based examples that work over the web. The first is Dragon Genetics which allows one to chose dragon genotype alleles to produce variations in phenotype. The graphics are fun and the science is good. The second interactive model is titled “Mendel’s Peas.” One can rerun Mendel’s experiments over the web. If these examples spark your interest, the good news is that there is free software that will allow a much deeper exploration of the genetic principles exhibited by the two examples. The software works on either Mac or PC; however, it requires a relatively recent vintage machine upon which to run. The software also requires a good amount of disk space and RAM. There are instructions on how to acquire and run the software. It will take a little time to download and set everything into motion. There is also older and less space-intensive software available called GenScope. For instructors looking for interactive computer software exploring principles of genetics, this is an interesting site. The larger Concord site has other resources that an instructor may wish to explore.
These sites were checked September 22. Previous ASCB columns reviewing Educational Web sites with the links to the sites may be found online.


Letters To The Editor

Evolution Position Defended

Dear ASCB Newsletter:
We are grateful for Robert Blystone’s recent mention of our institute in his list of evolution teaching resources [ASCB Newsletter, July 2000]. His description of our institute, however, is inaccurate in a few details. Our Center for the Renewal of Science and Culture (CRSC) is a separate program within Discovery Institute. The CRSC’s purpose is not to “explore the intelligent design approach to creationism” but rather to explore the evidence for intelligent design in biology, physics and chemistry.

While creationists generally base their views on biblical texts, the scientists associated with the CRSC see intelligent design as an inference motivated from scientific evidence, indeed, particularly evidence from molecular and cell biology. Additionally, many design theorists do not accept many of the other distinctives of creationism, such as a commitment to a young earth.

Additionally, Mr. Blystone describes our site as promoting “anti-evolution” views. Our fellows are not necessarily opposed to evolution in the broad sense of evidence of change in the history of life, but they are opposed to neo-Darwinism and specifically its denial of any evidence of actual design (as opposed to apparent design) in living organisms.

Again, we appreciate your interest in our site and thought we would offer these points of clarification for your readers.

Yours sincerely,
Stephen C. Meyer
Director, Center for the Renewal of Science and Culture
