Embryonic Research: It's More Than Just Cloning
Myrna Watanabe | Jan 6, 2002 | 7 min read
As some researchers pursue cloning and stem cell work, attracting media attention along the way, others concentrate on embryonic research that will help produce healthier babies. From esoteric work on genetic control mechanisms to studies of fetal nutrition, human genetics, and the effects of toxic substances on the fetus, scientists are trying to formulate a fuller picture of what occurs in utero. For example, scientists like Dennis Thiele and colleagues in the biological chemistry department a
Beyond Film: Laboratory Imagers
Jorge Cortese | Apr 1, 2002 | 9 min read
Years ago, researchers had only one data-imaging option: autoradiography. These scientists tagged samples—whether nucleic acid, protein, cell, or tissue—with radioactive labels, and captured images on film. Safety concerns, convenience, and sensitivity, spurred the development of alternative techniques, and today, researchers can choose from a range of options, including fluorescence, chemifluorescence, and chemiluminescence, in addition to autoradiography. Fluorescence occurs when
