Ken-ichi Noma, a geneticist at The Wistar Institute in Philadelphia, stands at a bench in his lab and squirts a sample of Saccharomyces pombe onto a microscope slide. He adjusts the microscope focus knobs, and an image of green, globular cells wavers on the monitor attached to his microscope. "How are you doing?" he asks the cells. "Are you happy?" Noma says that coddling his yeast cells is the key to success in the field of yeast genetics.
