In a perspectives piece in the New England Journal of Medicine, Harvard Medical School's Jules Dienstag says that science has changed since medical school admission requirements were first devised and that today's medical students need to be prepared for healthcare that involves genomics and informatics as well as to appreciate how the different systems of the body affect one another. "We need to teach in ways that reflect this complexity and that stimulate students to synthesize information across disciplines," writes Dienstag.
