Joseph Needham [4] was an embryologist and biochemist who is most noted in science for his studies on induction [5] in developing embryos. Needham worked with Conrad Hal Waddington [6] to attempt to identify the compound responsible for the organizer?s activity. Although he was not successful in discovering the chemical, he and Waddington learned much about the organizer [7]. Needham was a meti...

In 1920, F.A. entered Harvard Medical School, and graduated in 1924. He then worked as an intern at the Massachusetts General Hospital (M.G.H.) in the Department of Dr. J. Aub and W. Bauer where he was initiated into the field of the parathyroid glands and calcium metabolism. In 1927 and 1928, at Johns Hopkins Hospital in Baltimore, Albright together with Dr. R.

Viktor Hamburger [5] was an embryologist who focused on neural development [6]. His scientific career stretched from the early 1920s as a student of Hans Spemann [7] to the late 1980s at Washington University [8] resolving the role of nerve growth factor [9] in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he...

Recent observations of cod movement across stock boundaries are generally consistent with historical tagging data as well as information from other stock identification approaches. This working paper provides a historical context in which to consider recent tagging data for spatial delineation of cod stock assessments (TOR C). Introduction The objective of this report is to review the literatur...

Anterior temporal lobe resection controls seizures in 50–60% of patients with intractable temporal lobe epilepsy but may impair memory function, typically verbal memory following left, and visual memory following right anterior temporal lobe resection. Functional reorganization can occur within the ipsilateral and contralateral hemispheres. We investigated the reorganization of memory function ...

Nine species of the Parapolybia indica species-group in eastern parts of Asia are reviewed. Four new species are described: P. flava sp. nov. (Vietnam), P. crocea sp. nov. (Japan), P. nana sp. nov. (Vietnam), and P. albida sp. nov. (Vietnam). Parapolybia indica (de Saussure, 1854), P. bioculata van der Vecht, 1966 and P. tinctipennis (Cameron, 1900) are redescribed. The status is reinstanted fo...
