The mysterious expulsion of Steven Mosher

A detailed account is presented of information that has been provided by Stanford University and by unnamed "knowledgeable" sources on the events that led to Steven Mosher's expulsion from the Stanford anthropology department's doctoral program. The department will only say that, while in China, Mosher engaged in "illegal and seriously unethical conduct...and in doing so endangered his research subjects." Mosher contends that he was ousted because he had published an article in a Taiwanese magazine about third-trimester abortions in the Chinese village where he conducted his research.     

3 种生防细菌 2种药剂剂型对芒果 炭疽病菌的拮抗作用初探

3 种生防细菌短短芽孢杆菌（Br evi baci l l us br evi s）HAB-5、枯草芽孢杆菌（Baci l l ussubt i l i s）A178、萎缩芽 孢杆菌（Baci l l usat r ophaeus ）HAB-1、对多种植物病原菌具有较好的拮抗作用。通过优化条件培养、将 3种生防细菌制 备成胶悬剂（SC）和微胶囊（CS）两种剂型、以芒果炭疽病菌（Col l et ot r i chum gl oeospor i oi desPenz. ）C7-2 菌株为靶标病 菌、测试两种剂型对 3种菌拮抗能力的影响。 结果表明、在制备的 3 种生防菌的胶悬剂中、只有 A178 胶悬剂在稀释 10倍和 800倍时抑菌效果好于原始菌株、 其他的均弱于原始菌株、HAB-1 胶悬剂甚至失去了抑菌能力曰3种生防菌 微胶囊剂型中、A178 的 100~800 倍稀释浓度下抑菌效果好于原始菌株、 抑菌能力分别提高 0. 49% 、0. 29% 、3. 04% 曰 HAB-5的微胶囊剂型 10、100、400、800、1 000倍的稀释度下、 抑菌效果都高于原始菌株、 分别提高 5. 00% 、3. 30% 、 5. 11% 、2. 22% 、1. 74% 、4. 25% 、但 HAB-1 微胶囊剂型抑菌效果较其原始菌株减弱、说明微胶囊剂型能够增强 HAB-5 和 A178菌株对病原菌的抑菌作用。

植物甾醇营养强化剂在菜籽油中添加量的研究

对植物甾醇营养强化剂在菜籽油中添加方法进行了研究。结果表明,当油温度达到植物甾醇的熔点范围后,甾醇极易溶于菜籽油中,但冷却后部分甾醇又会以结晶形式析出;最终植物甾醇添加量与植物甾醇种类及其比例有关。在生产过程中,应边添加甾醇边适当搅拌以防止发泡与暴沸。     

Marston Warns of Threat to NIH

A direct sense of alarm for the future of the National Institutes of Health is evident in the farewell speech of former director Robert Q. Marston. Associates of Marston, who was abruptly dismissed this January, say he was told by the White House that the decision was for neither personal nor institutional reasons. Others have suggested that Marston was dismissed simply because he was appointed by a Democratic Administration. However this may be, Marston's valedictory, delivered on 27 April, is concerned not about his own situation, but that of the NIH.     

Three-dimensional structure identified from single sections

Errors in the identification of objects have been made frequently because of faulty interpretation of their flat images or sections. Such errors are perpetuated through a strange psychological chain reaction. 1) The first author who observes sections of an object, although presenting faithful pictures of sections of it, identifies its shape incorrectly. Such an initial mistake may be due to identification of the flat image with the object itself or to failure to consider the shape of the image as a function of the shape of the real object and the angle and level of cutting. 2) The first author describes verbally his personal concept of the object. 3) The reader reads the text of a publication before or without examining the pictorial evidence. 4) The reader's belief in the authority of the printed word immunizes him against critical evaluation of the evidence. 5) The reader regards a published opinion as a "fact." 6) A mechanism of suppression of new evidence is set up in the brain of the reader in favor of previously published, verbalized concepts. His brain unconsciously rejects new concepts that might arise intracerebrally. The printed word supersedes visual evidence. 7) A secondary mechanism parallels steps 3 to 6. An observer notices an unfamiliar figure in the microscope. Following established procedures for scientific investigations, he refrains from forming an opinion about his observation. Instead he rushes to the library searching for similar, published observations. If he finds a previous report about a similar shape, he accepts it as a "fact" and he "confirms" the previously printed viewpoint. Let me interject a personal experience concerning this mechanism. I investigated the arrangement of blood vessels in the human liver by means of corrosion preparations. The work was divided between an assistant and me. He was assigned the task of preparing drawings of two specimens. In his drawings he showed a structure which was absent from the specimens but had been described in a previous publication. This article shows simple ways for correct initial identification of shape and structure and for the breaking of the reverberating circuit of erroneous thinking.     

超干处理对蓝桉种子发芽及生理生化特性的影响

采用热空气恒温（50℃）干燥法对蓝桉种子进行超干处理,将蓝桉种子含水量由自然干燥的9．8％分别降至9％、8％、7％、6％、5％、4％、3％、2％、1％,研究超干燥处理对蓝桉种子发芽及生理生化特性的影响。结果表明:蓝桉种子耐脱水性较强,脱水至5％时,未发现种子活力明显下降,细胞膜能保持较好完整性,电导率最低,α—淀粉酶和脱氢酶活性高,各发芽能力指标在9个超干处理中最好。对各测定指标综合分析表明,蓝桉种子超干处理是完全可行的,最适含水率为5％,为蓝桉种子超干燥处理和贮藏提供了依据。     

Portraits of science. "The most versatile physicist of his generation"

P. M. S. Blackett (1897-1974) entered Cambridge University and the Cavendish Laboratory as a young veteran of the first world war. His innovative research with the Wilson cloud chamber resulted in photographic evidence of nuclear transformation and the existence of the positron. In the 1950s and 1960s, he helped to pioneer the use of paleomagnetic evidence in support of the theory of continental drift. A leader of operational research during the second world war, Blackett became an outspoken critic in the postwar period of American atomic policy and British development of nuclear weapons, taking on a public role for which he was sometimes criticized.

Three-dimensional structure of cholera toxin penetrating a lipid membrane

Two-dimensional crystals of cholera toxin bound to receptors in a lipid membrane give diffraction extending to 15 A resolution. Three-dimensional structure determination reveals a ring of five B subunits on the membrane surface, with one-third of the A subunit occupying the center of the ring. The remaining mass of the A subunit appears to penetrate the hydrophobic interior of the membrane. Cleavage of a disulfide bond in the A subunit, which activates the toxin, causes a major conformational change, with the A subunit mostly exiting from the B ring.

Free radicals in the stratosphere: a new observational technique

A new approach to in situ observations of trace reactive species in the stratosphere is described. A balloon-borne system, floating 40 kilometers above the earth's surface, successfully lowered and then retracted a cluster of instruments a distance of 12 kilometers on a filament of Kevlar. This instrument cluster is capable of detecting gas-phase free radicals at the part-per-trillion level. The suspended instrument array has excellent stability and has been used to measure atomic oxygen concentrations in the stratosphere.
