However soon reached a different conclusion and reasoned that “animal electricity” was a physical phenomenon Invention of “voltaic pile” (a.k.a., battery) inspired by (disprove) Galvani’s work to show that a steady electric current could be generated by two dissimilar metals between an electrolyte What if Galvani and Volta had worked together?

Sydney Brenner provided experimental evidence for the codon Francis Crick proposed the “adaptor hypothesis” involving a molecule ferrying the amino acids around, and putting them in the correct order corresponding to the nucleic acid sequence. These “ferrying” molecules were later found by Robert Holley and named it transfer RNAs.

    DATA BASE LEGISLATION IN THE DIGITAL AGE: BALANCING THE PUBLIC GOOD AND THE OWNERS' RIGHTS By Lynn M. Kennedy A Dissertation submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey In partial fulfillment of the requirements For the degree of Doctor of Philosophy Graduate Program in Communication, Information and Library Studies Written under the direction of Montague Kern, Ph. D. and approved by ________________________ ________________________ ________________________ ________________________ New Brunswick, New Jersey May 2013 Abstract of the Dissertation DATA BASE LEGISLATION IN THE DIGITAL AGE: BALANCING THE PUBLIC GOOD AND THE OWNERS' RIGHTS By Lynn M. Kennedy Dissertation Director: Montague Kern, Ph. D. This dissertation is a study of the impact of federal legislative proposals considered between 1997 and 2004 that offer protection to databases. It investigates the effect that the proposals had on the balance between the economic interests of owners and the right of the public to unfettered access to information. This identified legislation included proposed amendments to copyright law and laws that were proposed to specifically protect databases via misappropriation or unfair trade practices. The legislative proposals originated in the U.S House of Representatives, Committee on the Judiciary and Commerce Committee. ii The study identifies approaches to protection proposed by different constituent groups. For this work, witnesses testifying at Congressional hearings are categorized and associations are made between these categories and positions on the bills, views of the issue, and potential solutions are presented. The testimonies are analyzed by extracting the witnesses‘ descriptions of the issue, the source of the issue and recommended policy solutions.

Any opinions expressed in this memoir are those of the authors and do not necessarily reflect the views of the National Academy of Sciences. LESLIE ELEAZER ORGEL January 12, 1927–October 27, 2007 Elected to the NAS, 1990 Leslie Eleazer Orgel was a theoretical chemist and inves- tigator of the origins of life who made deep and lasting contributions in both of these scientific areas. He was born in London, England, on January 12, 1927, the second of three children of Simon and Deborah (Gnivisch) Orgel. His older brother Nevill was born on July 2, 1922, and died on December 28, 1957. His younger sister Delia was born on June 19, 1933, and currently resides in Silver Spring, Maryland. Leslie Orgel died on October 27, 2007, in San Diego, California, from pancreatic cancer. He is survived by his wife of 57 years, Alice (Levinson) Orgel; by his three children, Vivienne (b. April 4, 1955), Richard (b. November 29, 1956), and Robert (b. June 25, 1968); and by five By Jack D. Dunitz grandchildren. and Gerald F. Joyce After attending Dame Alice Owen’s School in London, which was evacuated during World War II to Bedford, England, Orgel studied chemistry at the University of Oxford, graduating in 1948 as BA with First Class Honours in Chem- istry. He then undertook graduate research with Leslie Sutton, senior chemistry tutor at Magdalen College and himself a distinguished physical chemist. Orgel’s1 first publication (1951) dealt with the semi-empirical calculation of electric dipole moments of conjugated heterocyclic molecules, and can be of no more than historical interest today.

It is now accepted that 1,25(OH)2D3 mediates its rapid actions on the control of phosphate homeostasis through its membrane receptor 1,25D3-MARRS (membrane associated rapid response steroid binding) protein.
