Camillo Golgi studied the central nervous system [2] during the late nineteenth and early twentieth centuries in Italy, and he developed a staining technique to visualize brain cells. Called the black reaction, Golgi's staining technique enabled him to see the cellular structure of brain cells, called neurons, with much greater precision. Golgi also used the black reaction to identify structure...

At the turn of the twentieth century, William Bateson [3] studied organismal variation and heredity of traits within the framework of evolutionary theory in England. Bateson applied Gregor Mendel's work to Charles Darwin [4]'s theory of evolution [5] and coined the term genetics for a new biological discipline. By studying variation and advocating Mendelian genetics, Bateson furthered the field...

any matrix f can be expressed as a function of the variables a,, instead of p, q, just as in classical theory we can use (6) as well as (7). The correspondence principle then follows from the asymptotic agreement of classical and quantum canonical transformations. It seems, nevertheless, of interest to have proved the correspondence principle as directly as possible without appeal to iterated t...

canopy density is linked to weaker or no thermophilisation. By offering more shadow, it appears, the trees are shielding the ground vegetation from the temperature rise. “We believe that the effect of the tree canopy is to moderate changes in temperature at the lower levels in the wood — particularly where, as is the case in much of Europe, woods have been becoming denser and shadier in recent ...

David Hunter Hubel studied the development of the visual system and how the brain processes visual information in the US during the twentieth century. He performed multiple experiments with kittens in which he sewed kitten?s eyes shut for varying periods of time and monitored their vision after reopening them. Hubel, along with colleague Torsten Wiesel, received the 1981 Nobel Prize in Physiolo...

Zanvil Alexander Cohn, an editor of this Journal since 1973, died suddenly on June 28, 1993. Cohn is best known as the father of the current era of macrophage biology. Many of his scientific accomplishments are recounted here, beginning with seminal studies on the granules of phagocytes that were performed with his close colleague and former editor of this Journal, James Hirsch. Cohn and Hirsch...
