Science_is_Flat Video Lectures (1) --- Max Perutz interview
sunon77 2009-3-16 06:27
Max Perutz: interview http://www.vega.org.uk/video/programme/1 A young man in his 17 claimed that only winning a Nobel prize can justify his career change from inheriting his father's textile factory to studying Chemistry. A researcher spent 22 years to elucidate one protein's structure, which has several thousands of atoms and was quite beyond any scientist's imagination at that time. A man finally proved that oxygen carrying ability of Haemoglobin comes from its structure and relevant chemical bonds. A pioneering biophysicist finally earned his Nobel prize in 1962, and was the founder of the Laboratory for Molecular Biology in Cambridge, the birthplace of modern molecular biology. It is nobody but Max Perutz. He also gave some useful tips how to run a scientifically active research group, how to choose a research topic and how to run a seminar to reward everybody. I am quite surprized to find that this great man had a unforgetable experience of being in prison of citizens of enemy countries in Canada for several years during the World War II. Amazingly, he, united with other scientists, opened a prison university to give bright kids a education even in such a distressing time. END

[译]投资与科研:闪着影响因子金光的发现
eloa 2009-2-23 09:51
Mickey Liu 发表于 2009-02-22 8:18 Ben Goldacre, 本译文已得到《卫报》授权,译者: lei, 原文 我在这个专栏是要讲业已腐败的医学研究,而不是着重于腮腺炎联合疫苗。由于本周关于疫苗的话题满载,所以希望你们不要误解。 Brian Deer 在《星期日泰晤士报》表示, Andrew Wakefield 发表于 1998 年的论文在出版前,报道的病历记录曾被修改过。而在过去七年以来的时间中,流行病学数据显示麻疹的发病率上涨了 20 倍,而且还在继续以指数形式增长。 在本周五,美国 Autism Omnibus 法庭召开的听证会指出,一项为期两年有 5000 名儿童参与的大规模项目显示,没有证据表明腮腺炎混合疫苗可以导致孤独症(与含汞的防腐剂工汞硫代水杨酸钠无关)。 腮腺炎联合疫苗(MMR) 本来就没有理由去相信腮腺炎混合疫苗会导致孤独症。但反对疫苗的运动人士还在并将继续误导群众,扼杀不同声音甚至抹黑疫苗研究。尽管抗议者只是着墨于疫苗坏的例子(可能也是过于简单化),但疫苗研究中的确存在林林总总的问题,所以坚持己见不被别人的愚蠢所左右是很重要的。 这星期的英国医学杂志发表了一篇复杂的研究报告,而这篇报告成了有史以来发表的最具颠覆性的研究。研究分析了关于流感疫苗现有的所有文章,试图发现研究资金的来源是否影响到课题的质量、概述的准确性和发表期刊的层次。尽管研究结果用到其他领域也很合理,但这篇报告着重于投资来源和研究的关系。 而在我设想的理想社会中,无论研究发表在何种杂志,也不管文章的概述写的有多差,都应该以愉快的心情和殷勤的态度去面对每一篇学术论文。但返回现实看个例子,据统计每个月仅仅和 GP care 组织相关的各种学术杂志就刊登包括论文,通讯和社论在内,超过 7000 篇的文章。新的研究发现很重要,而客观评价这一周的研究就需要熟悉流行病学的临床医生们超过 600 小时的时间。因此人们必然会只去读读有名的期刊或者文章概述,即文章的重点。 我们已经知道的是,产业资助的课题通常会得出对赞助药商有利的结果,而在今天疫苗的例子一样符合上述的规律,政府资助的研究往往很少会得出力挺疫苗的结论。另一个已知的现象是,质量差的研究往往更容易得到阳性结果,无论是药物、顺势疗法还是什么。我们得到的数据是 70% 阳性结果的研究,本身的质量都不怎么样。 但 Tom Jefferson 和及其同仁,第一次把文章发表在什么杂志这个因素考虑在内了。学术界用期刊的影响因子来评价这本杂志的学术水平:即依靠这本期刊的文章平均被其他研究引用多少来评价这本期刊。 92 本政府资助的研究期刊平均影响因子是 3.74 ,而 52 本由产业全部或半资助的研究期刊平均影响因子是 8.78 。制药工业资助的研究报告更容易被更大、更有名的期刊采用。 由于我们无法解释上述的现象,这个问题变得很有趣。比较政府资助和产业资助的研究,两者的研究方法都是一样的严谨;两者的数据采集规模也不相上下。更重要的是发表文章的人都抱着一样的信念;每个人都极尽全力想把自己的文章投到更有名的杂志中去。 一个颇具恶意的猜测可能解决我们对于产业资助研究更为成功的疑惑。原因就是,期刊也是大型国际公司经营的商业,他们不光依靠产业的广告来赚钱。期刊更可以通过销售印刷精美的单行本获取巨额利润,再加上优雅的翻译,那些关于药物的文章就走向世界了。但想到这种鬼主意的人们可能需要为现有的数据找到一个标新立异的解释。 英国医学杂志刊登的研究是一个很好的例子来证明一个事实,即整个学术界不仅在用统计学和数量分析的工具打造出了一个恶心的政治、文化问题,而且他们通过这样的方式蜷起奔跑的双腿固步自封起来。而学术研究本来可以将人类行为的全部领域都包容进去,也应该可以走得更远。 但更大的悲剧也许是, Jefferson 等人揭露出的问题能够被很轻易的解决。在理想世界里,所有药物研究都应该在商业上和药物的生产与销售分离开来,而且所有的杂志都应该是开放、免费的。但直到现在,学术界总是饱含感激的表示所有的学术研究经费来自药厂的赞助,而且由于编辑和出版社的决策实在是太有影响力了,所以让他们每年公开期刊所有收入来源与开销去处这个要求,并不过分。因为现在,最有意思的事情是我们甚至不知道科学期刊是如何运作的。 摩西:『汝当遵从 Impact Factor 为唯一真神!』 Frankenstein:『吾等信受奉行,至死不悔。』

人生是用来享受的,以享受的心态去学习,念书就不会是累事儿,以享受的心态去工作,科研就是充满乐趣的时光。每每和学生、和同事谈起培养兴趣,享受人生,享受研究带来的美好的时候,总是有很多人无法进行沟通,在一些人的字典里头,玩就是吃喝玩乐;我们对享受的定义不一样,对人生的理解有差异哈。在无限的乐趣中工作、生活,于是人生的意义就不再仅仅是评职称,当博导,开心的生活,就是人生的成功。

Do science like ina competition. Champion is only one in an campetition event. Only a few successful professional athletes guard their positions in the end. When they lose physical strength, they gain experience andchange role to become a coach going on to screen out champions. This is the great life of a scientist.

Science:Preparing Your Manuscript for Initial Submission
ibnsmm 2008-12-21 13:16
Information on acceptable lengths of papers in various categories can be found on our general information for authors page. One page in the journal contains approximately 1000 words and one small figure. Use double-spacing throughout the text, references and notes, tables, and figure legends; leave margins of at least 1.25 inches (~3 cm). Electronic files should be formatted for standard U.S. letter paper (8.5 11). Here are some things to keep in mind in crafting a manuscript for a typical Science Research Article, Report, or Review submission: Titles should be no more than 90 characters. One-sentence summaries capturing the most important point should be submitted for all papers. Authors and their affiliated institutions , linked by superscript numbers, should be listed beneath the title on the opening page of the manuscript. Subheadings are used only in Research Articles, Reviews, and invited special-issue articles. Use descriptive clauses, not full sentences. Two levels of subheadings may be used if warranted; please distinguish them clearly. Abstracts explain to the general reader why the research was done and why the results are important. They should start with some brief BACKGROUND information: a sentence giving a broad introduction to the field comprehensible to the general reader, and then a sentence of more detailed background specific to your study. This should be followed by the RESULTS, or if the paper is more methods/technique oriented an explanation of OBJECTIVES/METHODS and then the RESULTS. The final sentence should outline the main CONCLUSIONS of the study, in terms that will be comprehensible to all our readers. The abstract should be 125 words or less. Text starts with a brief introduction describing the paper's significance, which should be intelligible to readers in various disciplines. Technical terms should be defined. Symbols, abbreviations, and acronyms should be defined the first time they are used. All tables and figures should be cited in numerical order. References and notes (see examples of Science reference style ) are numbered in the order in which they are cited, first through the text and then through the references and the table and figure legends. Each reference should have a unique number; do not combine references or embed references in notes (this is a change from previous Science style). Any references to in-press manuscripts or personal communications should be given a number in the text and placed, in correct sequence, in the references and notes. Such references should not, however, be used to support claims or conclusions. We do not allow references to unpublished data in support of claims or conclusions; necessary data should be included in the manuscript, its Supporting Online Material, or an approved archival database. Do not use op. cit. or ibid in references. Acknowledgments , including all funding information, accession numbers, and any clarification regarding conflicts of interest of the authors, should be gathered into a brief statement at the end of the references and notes. Tables should be included after the references and should supplement, not duplicate, the text. Each table should be presented with its legend double-spaced above the table. The first sentence of the legend should be a brief descriptive title. Every vertical column should have a heading consisting of a title with the unit of measure in parentheses. Units should not change within a column. Figure legends should be double-spaced in numerical order. No single legend should be longer than about 200 words. Nomenclature, abbreviations, symbols, and units used in a figure should match those used in the text. The figure title should be given as the first line of the legend. Any individually labeled figure parts or panels (A, B, etc.) should be specifically described by part name within the legend. Schemes (e.g., structural chemical formulas) can have very brief legends or no legend at all. Schemes should be sequentially numbered in the same fashion as figures. Supporting online material is posted permanently on Science Online, is linked to the manuscript, and is freely available. Supporting online material includes materials and methods, plus extra text, figures, tables, and references that are important for the integrity of the paper. Online sound files, video clips, and more complex data may also be acceptable, as described in our detailed instructions for preparing and submitting supporting online material . Figures should be submitted electronically as part of the manuscript file upload . For initial submission, figures may be embedded directly in the manuscript file; allowable formats for manuscript files are .pdf, .ps, .eps, .prn, .doc, .wpd, as discussed below . Do not send irreplaceable artwork; we will not return submitted figures or disks. Authors submitting revised manuscripts after peer review will receive more specific information about electronic submission of art for publication; at the initial-submission stage, we ask that authors consult our tips for preparing efficient figures to assure a smooth manuscript upload. Most figures will not be relabeled by Science . The size of figures, when printed, will usually be 5.5 cm (2.25 inches or 1 column) or 12.0 cm (4.75 inches or 2 columns) in width. Bar graphs, simple line graphs, and gels may be reduced to a smaller width. Symbols and lettering should be large enough to be legible after reduction. Avoid wide variation in type size within a single figure. In the printed version of the figure, letters should be about 7 points (2 mm) high. High-resolution images can be included as supporting online material. Science does not allow certain electronic enhancements or manipulations of micrographs, gels, or other digital images. Figures assembled from multiple photographs or images must indicate the separate parts with lines between them. Linear adjustment of contrast, brightness, or color must be applied to an entire image or plate equally. Nonlinear adjustments must be specified in the figure legend. Selective enhancement or alteration of one part of an image in not acceptable. In addition, Science may ask authors of papers returned for revision to provide additional documentation of their primary data. If possible, use scale bars in place of, or in addition to, magnification numbers; the scale bar units should be specified in the figure legend. In gels, the lanes should be numbered and identified by number in the figure legend. Graphs should be labeled on the ordinate and abscissa with the parameter or variable being measured, the units of measure, and the scale. Scales with large or small numbers should be presented as powers of 10. Definitions of symbols should usually appear in the figure legend and not in the figure. Simple solid or open symbols ( , , , , , , , and ) reproduce well. Avoid the use of light lines and screen shading . Instead, use black-and-white, hatched, and cross-hatched designs for emphasis. Use heavy lines or boxes for emphasizing or marking off areas of the figure. Additional design guidelines can be found in our tips for preparing efficient figures . Composite figures should be labeled A, B, C, etc. Digital color art should be submitted as CMYK (Cyan, Magenta, Yellow, Black) rather than RGB (Red, Green, Blue). Composite figures should be labeled A, B, C, etc. Authors are charged $650 for publication of the first color figure and $450 for each additional color figure. There is an additional charge for color figures in the reprints. Lettering in Helvetica font is preferable for figures. Use boldface type for axis labels and for part labels (A, B, etc.) in composite figures; use italic type only as it would be used in the text (e.g., for variables and genes). The first letter of each entry should be uppercase; otherwise, use uppercase letters as they would be used in the text (e.g., for acronyms). Sequences may be reduced considerably, so the typeface in the original should be clear. There should be about 130 characters and spaces per line for a sequence occupying the full width of the printed page and about 84 characters and spaces per line for a sequence occupying two columns. Units should be metric and follow SI convention.
