C. O. Whitman and the American Society of Zoologists

C. O. Whitman (1842–1910) studied under Louis Agassiz,Anton Dohrn, and Rudolph Leuchart. Under the influence of E.S. Morse, Whitman served as the second professor of zoologyat the University of Tokyo (1880–81). For three yearshe was assistant to Alexander Agassiz at the Museum of ComparativeZoology. Between 1883 and 1886 Whitman was editor of the Departmentof Microscopy for the American Naturalist. He became the firstdirector of the Marine Biological Laboratory at Woods Hole,serving until 1908, and built that institution into an internationallyfamous center for education and research. He also became firstprofessor of Zoology at the University of Chicago where he remainedfor life. In 1887 he founded the Journal of Morphology, andlater Biological Lectures, and Zoological Bulletin which becamethe Biological Bulletin. His own research was in the fieldsof embryology, heredity, and evolution. In 1890 he, with colleagues,founded the American Morphological Society which became theAmerican Society of Zoologists over a period of 13 years (1901–13)by the union of regional groups. Whitman played a leading rolein the founding and early history of the Society.     

Finding a suitable system scale to optimize program performance on software DSM systems

Recently, software distributed shared memory systems have successfully provided an easy user interface to parallel user applications on distributed systems. In order to prompt program performance, most of DSM systems usually were greedy to utilize all of available processors in a computer network to execute user programs. However, using more processors to execute programs cannot necessarily guarantee to obtain better program performance. The overhead of paralleling programs is increased by the addition in the number of processors used for program execution. If the performance gain from program parallel cannot compensate for the overhead, increasing the number of execution processors will result in performance degradation and resource waste. In this paper, we proposed a mechanism to dynamically find a suitable system scale to optimize performance for DSM applications according to run-time information. The experimental results show that the proposed mechanism can precisely predict the processor number that will result in the best performance and then effectively optimize the performance of the test applications by adapting system scale according to the predicted result.

Biochemical contacts and collaborations between China and the U.K. since 1911

Scientific contact lies at the heart of research and that between China and the U.K. is an important example of how it can come about. In 1911, when the Biochemical Society began, U.K. science was developing fast with profound discoveries in physics (the Rutherford atomic model) and biochemistry (the discovery of vitamins). In China, however, there was great social and political instability and a revolution. Since then, the turbulence of two world wars and a variety of deep global political tensions meant that the contacts between China and U.K. did not reflect the prodigious growth of biochemistry. There was, however, one particular and remarkable contact, that made by Joseph Needham, an outstanding biochemist. He visited China between 1943 and 1946, contacting many Chinese universities that were severely dislocated by war. Showing remarkable diplomatic abilities, Needham managed to arrange delivery of research and teaching equipment. His activities helped the universities to carry out their functions under near-impossible conditions and reminded them that they had friends abroad. Most remarkably, Joseph Needham developed an extraordinary grasp of Chinese culture, science and history and he opened the West to the extent and importance of Chinese science. Formal scientific and intellectual contacts between the scientific academic bodies in China and U.K., notably the Chinese Academy of Science and the Royal Society, resumed after British recognition of the Chinese Communist government in 1950. The delegations included outstanding scientists in biochemistry and related disciplines. Research activities, such as that concerning influenza, were soon established, whereas institutions, such as the Royal Society and the Wellcome Trust, acted a little later to support research. The outcomes have been long-term collaborations in such areas as insulin structure and function. There are now numerous joint activities in biochemistry and biomedicine supported by the MRC (Medical Research Council), BBSRC (Biotechnology and Biological Sciences Research Council), NERC (Natural Environment Research Council), EPSRC (Engineering and Physical Sciences Research Council) and UKRC (UK Research Councils). The present contacts and the associated research are very considerable and growing. It is clear that biochemistry in both countries has much to offer each other, and there is every reason to believe that these contacts will continue to expand in the future.     

Contribution of late Professor T. C. Tung to the experimental embryology of Amphioxus

Professor T. C. Tung (Fig. 1) was a prominent experimental embryologist in China. He was born in Jin County, Zhejiang Province, China in 1902. After he obtained his Bachelor's degree from the Department of Biology, Fudan University, Shanghai in 1927, he was appointed as a teaching assistant in that department until he moved to Belgium in 1930. He studied as a graduate student in Professors A. Brachet and A. M. Dalcq's laboratory at the Universite Libre de Bruxelles, Belgium and obtained his Doctor of Science degree there in 1934. During that period, he made two short working visits to the Institute of Marine Biology in France and took one training course at Cambridge University (UK). In 1934, he was invited to return to China as a Full Professor to teach at several Chinese universities, (Shandong University in Qingdao, Shandong Province; the National University in Nanjing; and Fudan University in Shanghai). He spent 1 year at Yale University (USA) between 1948 and 1949 as an invited scientist in a joint research project and finally returned to China in 1949. He was Chairman of the Department of Zoology, Shandong University in Qingdao (1949-1952), Vice-President of Shandong University (1952-1960), Director of the Marine Biological Institute, the Chinese Academy of Sciences (CAS) in Qingdao (1949-1958), Director of the Institute of Oceanology (CAS) in Qingdao (1959-1966), Director of the Institute of Zoology (CAS) in Beijing (1960-1962), member of CAS since 1955, Vice-Chairman of the Biological and Geographical Division of CAS (1955-1958), Chairman of the Biological Division of CAS (1959-1979) and Vice-President of CAS in Beijing (1978-1979). In spite of his administrative duties, he spent most of his life conducting bench work in his laboratories at the Institutes of Oceanology and Zoology, CAS, respectively, until he passed away in March 1979. Professor Tung's main research interest was with classic experimental studies on the determination of the egg axis and symmetry planes of fertilized eggs, early differentiation and organizing substances of egg cytoplasm, induction between embryonic cells and cytoplasm in embryogenesis, immunological studies on nuclear transplanted eggs, and cell fusion etc., in several types of animals. He conducted his experiments on a number of invertebrates (ascidians and Amphioxus) and vertebrates (fish and amphibians) by means of very skillful microsurgical operations and the nuclear transplantation method. Among these topics, his studies on the organization and developmental potency of Amphioxus eggs were unique. His important contribution to this research field involved not only establishing a practical method for collecting and using this rare animal for experimental purposes, but also clarifying controversy about the nature and early development of its eggs. He also provided conclusive evidence to determine its evolutionary position between invertebrates and vertebrates. The present article briefly reviews the main results obtained by Professor Tung and his colleagues on Amphioxus. Although their original articles were written both in Chinese and English, many international readers may not even know those original works because they were only published in scientific journals inside China from the 1950s. Comments and discussion on the experimental results of Amphioxus research by Tung's group and those from other earlier authors are also included.     

His Own Synthesis: Corn, Edgar Anderson, and Evolutionary Theory in the 1940s

Tracing the contributions of Edgar Anderson (1897--1969) of the Missouri Botanical Garden to the important discussions in evolutionary biology in the 1940s, this paper argues that Anderson turned to corn research rather than play a more prominent role in what is now known as the Evolutionary Synthesis. His biosystematic studies of Iris and Tradescantia in the 1930s reflected such Synthesis concerns as the species question and population thinking. He shared the 1941 Jesup Lectures with Ernst Mayr. But rather than preparing his lectures as a potentially key text in the Synthesis, Anderson began researching Zea mays -- its taxonomy, its origin, and its agronomic role. In this study, Anderson drew on the disciplines of taxonomy, morphology, genetics, geography, anthropology, archaeology, and agronomy among others in his own creative synthesis. Though his maize research in the 1940s represented the most sustained work of his career, Anderson was also drawn in many directions during his professional life. For example, he enjoyed teaching, working with amateurs, and popular writing. This revised version was published online in July 2006 with corrections to the Cover Date.     

Govindjee at 80: more than 50 years of free energy for photosynthesis

We provide here a glimpse of Govindjee and his pioneering contributions on the two light reactions and the two pigment systems, particularly on the water–plastoquinone oxido-reductase, Photosystem II. His focus has been on excitation energy transfer; primary photochemistry, and the role of bicarbonate in electron and proton transfer. His major tools have been kinetics and spectroscopy (absorption and fluorescence), and he has provided an understanding of both thermoluminescence and delayed light emission in plants and algae. He pioneered the use of lifetime of fluorescence measurements to study the phenomenon of photoprotection in plants and algae. He, however, is both a generalist and a specialist all at the same time. He communicates very effectively his passion for photosynthesis to the novice as well as professionals. He has been a prolific author, outstanding lecturer and an editor par excellence. He is the founder not only of the Historical Corner of Photosynthesis Research, but of the highly valued Series Advances in Photosynthesis and Respiration Including Bioenergy and Related Processes. He reaches out to young people by distributing Z-scheme posters, presenting Awards of books, and through tri-annual articles on “Photosynthesis Web Resources”. At home, at the University of Illinois at Urbana-Champaign, he has established student Awards for Excellence in Biological Sciences. On behalf of all his former graduate students and associates, I wish him a Happy 80th birthday. I have included here several tributes to Govindjee by his well-wishers. These write-ups express the high regard the photosynthesis community holds for “Gov” and illuminate the different facets of his life and associations.     

Cell volume regulation and ischemic tissue damage

Over years of friendly meetings with Professor Aharon Katzir-Katchalsky, many topics of mutual interest were discussed. He was the ideal person to come to with a problem. After being subjected to his critical, analytic mind, most research problems seemed simple, more clearly defined and understandable. His broad biologic and scientific background grew from an apparently insatiable interest in all natural phenomena. He generously shared his knowledge and imparted his wisdom with a share of his own infectious excitement. He was quick to sense the significance of understanding of biological processes to their practical application. For this reason it seems appropriate to relate the progress made in the understanding of cell volume regulation, which had been discussed on several occasions with him, to its possible significance as a factor in disease processes.Dr. Frega is a Fellow of the National Kidney Foundation, Inc., 1972–73.     

High Affinity of the 5'-Upstream Region of a Winged Bean Chymotrypsin Inhibitor Gene for Nuclear Matrix

The 5'-upstream region of a winged bean chymotrypsin inhibitorgene (WCI-3b) was found to have a high affinity for nuclearmatrix. The region, named WCI-3b MAR (matrix attachment region),is highly A+T-rich and contains multiple sites interacting withnuclear matrix. A MAR was also found in the corresponding regionof the WCI-x gene, another active gene of the WCI family. SeveralMAR-binding proteins were detected in the wheat nuclear matrix. ⁴Present address: Friedrich Miescher Institute, P.O.

He has also played an important role in the establishment of history and philosophy of biology as viable professional disciplines.     

Science and society: Asilomar and after: A decade of the new biology

In February 1975, in Pacific Grove, California, the Asilomar Conference took place, sponsored by the U.S. National Academy of Sciences and convened by the Academy's Committee on Recombinant DNA Molecules, of which Paul Berg was the Chairman. This conference recommended guidelines for recombinant DNA research, and the history of subsequent sets of guidelines formed the major theme of six articles that appeared in Vol. 1 of BioEssays, authored by Dewitt Stetten, Jr, with the collaboration of William Gartland and Bernard Talbot and entitled ‘The Road to Asilomar: Reminiscences of the Recombinant DNA Story’.¹ The U.S. National Research Council recently commissioned for its News Report (volume XXXV, March 1985, 1A–16A) a retrospective article on Asilomar, written by Susan Walton. That article is exerpted here with the permission of the National Research Council.

Introduction and Institutionalization of Genetics in Mexico Ana Barahona,Susana Pinar and Francisco J. Ayala

We explore the distinctive characteristics of Mexico’s society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934–1940), which was primarily directed towards improving the condition of small Mexican farmers. Taboada is the first Mexican post-graduate investigator in phytotechnology and phytopathology, trained at Cornell University and the University of Minnesota, in 1932 and 1933, respectively. He was the first investigator to teach plant genetics at the National School of Agriculture and wrote the first textbook of general genetics, Genetics Notes, in 1938. Taboada’s most important single genetics contribution was the production of “stabilized” corn varieties. The extensive exile of Spanish intellectuals to Mexico, after the end of Spain’s Civil War (1936–1939), had a major influence in Mexican science and characterizes the second stage. The three main personalities contributing to Mexican genetics are Federico Bonet de Marco and Bibiano Fernández Osorio Tafall, at the National School of Biological Sciences, and José Luis de la Loma y Oteyza, at the Chapingo Agriculture School. The main contribution of the Spanish exiles to the introduction of genetics in Mexico concerned teaching. They introduced in several universities genetics as a distinctive discipline within the biology curriculum and wrote genetics text books and manuals. The third stage is identified with Alfonso León de Garay, who founded the Genetics and Radiobiology Program in 1960 within the National Commission of Nuclear Energy, which had been founded in 1956. The Genetics and Radiobiology Program rapidly became a disciplinary program, for it embraced research, teaching, and training of academics and technicians. The Mexican Genetics Society, created by de Garay in 1966, and the development of strains and cultures for genetics research were important activities. One of de Garay’s key requirements was the compulsory training of the Program’s scientists for at least one or two years in the best universities of the United States and Europe. De Garay’s role in the development of Mexican genetics was fundamental. His broad vision encompassed the practice of genetics in all its manifestations.     

Exploiting redundancy to boost performance in a RAID-10 style cluster-based file system

While aggregating the throughput of existing disks on cluster nodes is a cost-effective approach to alleviate the I/O bottleneck in cluster computing, this approach suffers from potential performance degradations due to contentions for shared resources on the same node between storage data processing and user task computation. This paper proposes to judiciously utilize the storage redundancy in the form of mirroring existed in a RAID-10 style file system to alleviate this performance degradation. More specifically, a heuristic scheduling algorithm is developed, motivated from the observations of a simple cluster configuration, to spatially schedule write operations on the nodes with less load among each mirroring pair. The duplication of modified data to the mirroring nodes is performed asynchronously in the background. The read performance is improved by two techniques: doubling the degree of parallelism and hot-spot skipping. A synthetic benchmark is used to evaluate these algorithms in a real cluster environment and the proposed algorithms are shown to be very effective in performance enhancement.

Ivan Djaja (Jean Giaja) and the Belgrade School of Physiology

The founder of physiology studies in the Balkans and the pioneer of research on hypothermia, Ivan Djaja (Jean Giaja) was born 1884 in L'Havre. Giaja gained his PhD at the Sorbonne in 1909. In 1910 he established the first Chair of Physiology in the Balkans and organized the first Serbian Institute for Physiology at the School of Philosophy of the University of Belgrade. He led this Institute for more than 40 subsequent years. His most notable papers were in the field of thermoregulation and bioenergetics. Djaja became member of the Serbian and Croatian academies of science and doctor honoris causa of Sorbonne. In 1952 for the seminal work on the behavior of deep cooled warm blooded animals he became associate member of the National Medical Academy in Paris. In 1955 the French Academy of Sciences elected him as associate member in place of deceased Sir Alexander Fleming. Djaja died in 1957 during a congress held in his honor. He left more than 200 scientific and other papers and the golden DaVincian credo "Nulla dies sine experimento". His legacy was continued by several generations of researchers, the most prominent among them being Stefan Gelineo, Radoslav Andjus and Vojislav Petrovi?.
