...influence of wrongly interpreted genetics research on social and political attitudes may result in an eugenics movement to eliminate defective members from society, Jonathan R. Beckwith '57, professor of Microbiology and Molecular Genetics at Harvard Medical School said yesterday...
...rigidity of the disease, patients could suffer partial paralysis and loss of speech. Now, most Parkinson's victims can be relieved by a drug known as levodihydroxyphenylalanine, or L-dopa. First used successfully by George Cotzias of the Brookhaven National Laboratory, L-dopa provides a classic example of molecular chemistry at work. Normal movement depends in large part upon the action of dopamine, one of the brain's most important chemical transmitters. Parkinson's disease results from a degeneration of the cells that help produce this chemical. By boosting the level of dopamine in the brain...
...ever succeeds in reaching this goal, most neuroscientists today agree that much of the credit will belong to the author of that statement, Dr. Francis Otto Schmitt, a professor at the Massachusetts Institute of Technology. Although he is a skilled researcher in molecular biology, Schmitt is best known in his profession as a scientific impresario. He is the founder, chairman and most enthusiastic member of the M.I.T.-sponsored Neurosciences Re search Program. It is from the work of this group that a comprehensive theory of brain function could well emerge...
Schmitt pioneered the use of X-ray diffraction and polarization optics to explore the inner workings of cells, and studied molecular biology before the term was invented. Head of the team that was first in the U.S. to use an electron microscope for studying biological tissues, he is also well known for his work on collagen, the clear protein material that fills the spaces between cells...
...them up for silage." In her recent book on the subject, Power Over People (Oxford University Press; $7.50), Physicist Louise B. Young gives one possible reason: the discharge of high voltages into the air can produce ozone, a form of oxygen with three (rather than two) atoms in its molecular makeup, and oxides of nitrogen. Ozone can oxidize or "burn" healthy tissue, and nitrogen oxides form nitrous acid and one of the major components of smog. All of these might well affect people and plants that live near the lines...
