Brandeis Biophysicist Herman Epstein readily concedes that he really doesn't "give a damn" about euglena, the single-celled aquatic organisms whose elusive qualities he has been tracking most of his professional life. What keeps him at the job is the thrill of the chase and the fascinating fundamental questions about life that the pursuit raises. In 13 years of teaching science at Brandeis, Epstein was dismayed by the fact that the traditional textbook-and-lecture approach continually failed to convey his own excitement about science. The introductory biology course had become, he says, "the most disliked course...
...Euglena gracille, a simple, one-celled organism--used in the laboratory to measure the level of vitamin B-12 in the blood of anemic patients--is now being employed in studies to determine the effect of metal deficiencies on nucleic acid and protein metabolism...
...Apparently," Dr. Wacker concluded, "zinc may be required to maintain the functional and structural integrity of euglena...
...species of animals, which live parasitically off the food-making ability of the plant world, these little creatures contain chlorophyll and hence can synthesize food out of water, carbon dioxide in the presence of light. And unlike any of the 250,000 species of plants, one of these animals-Euglena rubra by name-changes its color, now red, now green, to control the amount of light it uses. This phenomenon was explained last week in Physiological Zoology by Leland P. Johnson of Drake University and Theodore Louis Jahn of the University of Iowa...
