Extractions: It is a well known story that I will only summarize for comparison to what happened in France. Johns Hopkins Medical School was the first institution to establish full-time clinical teaching, with special attention to research. The two persons largely credited with the innovation were William Osler and William Welch, a British and an American physicians, both of them trained in Germany. (German training was not unusual for Americans at the end of the 19th and beginning of the twentieth century. According to Rosemary Stevens, over 15,000 Americans studied medicine in Germany between 1870 and 1914.) The organizing principles of scientific medicine are simple (in theory). They consist in uniting under one roof: 1) Treatment (care of patients) 2) Training of doctors (bedside teaching) 3) Laboratories for clinical and basic research These were, in fact, the principle conclusions of the famous report from the Carnegie Foundation, by Abraham Flexner in 1910, on medical instruction in Europe and North America.

Extractions: John F. Kennedy ... Musik Verden - Nobelpriser Den svenske kemiker Alfred Nobel var blevet en velhavende mand, som følge af at han havde opfundet dynamitten. Ved sin død i 1896 efterlod han sig cirka 32 millioner kroner. Disse havde han testamenteret til en stiftelse. Renterne af de penge Nobelstiftelsen rådede over gik til en række priser. Disse priser var opdelt i følgende kategorier: Hvert år på Alfred Nobels dødsdag - 10. december - tildeltes priserne personer, som havde gjort sig fordelagtigt bemærket. I 1960erne modtog følgende Nobelprisen: Fredspris Albert Luthuli (Sydafrika) Dag Hammarskiöld (Sverige) Linus C. Pauling (USA) Den Internationale Røde Kors Komite Martin Luther King Jr.(USA) UNICEF Rene Cassin (Frankrig) ILO

Extractions: In 1932-1933 a grant from the Rockefeller Foundation enabled him to spend a year in Heidelberg in the laboratory of Otto Meyerhof . He studied haematin - a growth factor for the flagellates - the specificity of protohaematin, its quantitative effect on growth, and the part it played in the respiratory catalyst system. Then in 1936, again with the aid of a grant from the Rockefeller Foundation, Lwoff and his wife spent seven months in Cambridge in the laboratory of David Keilin; factor V, which is required by Haemophilus influenzae , was identified with cozymase and its physiological role for the bacterium was defined. The observation of isolated bacteria led him to the conclusion that lysogenic bacteria did not secrete bacteriophages, that the production of bacteriophages led to the death of the bacterium, and above all that this production must be induced by external factors. It was this hypothesis which, together with Louis Siminovitch and Niels Kjeldgaard, led Lwoff to discover the inductive action of ultraviolet irradiation (1950).

Extractions: Tetrahymena Whole-Genome Sequencing Project: A Concept Paper November 5, 2001 Preface . To facilitate access to the large diversity of information, this concept paper is organized into two components: Main and Appendix. The Main document contains the introductory overview of the case for sequencing the Tetrahymena genome, the concise description of the sequencing and annotation project, and the specific answers to the NonMammalian Models Committee questionnaire. The Appendix expands on the coverage of two topics in the main document: advanced molecular genetic tools and unique or very special studies that would be enabled by the availability of the genome sequence. The latter are grouped by topic into numbered tables for easy reference from the main document. All the cited references are listed in the Appendix, organized so that related references are generally clustered together. Page numbers in tables of contents (main and appendix) may be sensitive to software print settings and are therefore only approximate.

Extractions: Bacteriophage l is a prime example of how a virus can "vanish", i.e., become hidden within the cell only to reappear in later cell generations. The mechanism of l 's disappearance was the subject of much debate; figuring out how it happens earned a Nobel Prize. The mechanism parallels that of the regulation of the lac operon and took advantage of bacterial genetics. Within a few years of the discovery of the bacteriophage, lysogenic bacterial strains were found which appear to "carry" bacteriophages, in the sense that phage particles are always present in the culture fluid of such strains. It was soon realized that this association of phage and bacteria cannot be of a casual nature, since it is impossible to permanently free lysogenic strains from the phage they carry by methods whih ought to kill or remove the virus particles, such as heating, anti-phage serum neutralization, or single colony purification. The nature and significance of lysogeny then remained a subject of insense controvery for about 30 years... Nevertheless, a few bacteriologists... already envisioned that lysogeny represents an innate capacity of bacterial cells for phage production. The bacteriologists who believed that "lysogeny represents an innate capacity of bacterial cells for phage production" were Bordet, who said in 1925 that "The faculty to reproduce bacteriophages is inscribed into the hereditary weft of the microbe" and Burnet (of immunology fame) and McKie, who wrote in 1929 that "The permanence of the lysogenic character make it necessary to assume (that) the presence of bacteriophage...is a part of the hereditary constitution of the strain."

Extractions: Guide to the Records of Phyllis Margaret Rountree 'Well now, it was very nice having you here dear, but we don't employ women permanently'. This is how Phyllis Rountree recalled the attitude of her first boss, Professor James A. Prescott, to the end of Rountree's three-year CSIR fellowship in 1934 at the Waite Agricultural Institute in Adelaide. It was a time of shortage of scientific workers in Australia, not addressed until tertiary education was expanded under the Menzies Government well into the 1960s. However, in an environment where her all-male scientific colleagues did not even deign to chat with the young Phyllis at afternoon tea, employment opportunities for the outstanding graduate from Melbourne University were not straightforward. Rountree recounted that her work at the Institute had proceeded 'in a rather leisurely sort of way' and she 'thoroughly enjoyed' herself. Concluding her fellowship, Rountree presented a paper that embodied three years of research into the problem of soil salination to the fastidious Professor Prescott, and he accepted it without so much as an addition. Nonetheless, the Institute did not offer Rountree a continuing position, and later she reflected that 'if I'd been a man, they probably would have found me something'. Rountree was a pioneer from the periphery, like many of her Australian colleagues, in work of practical and theoretical importance. As a woman, she received belated recognition of her work, and did not always step forward as far as her male colleagues to take credit for her own valuable and painstaking work.
