Prominent researcher Gerald Denis explains the tight relationship between medical research and progress in medical care. Recent abrupt cuts to research funding and science agencies such as NIH have disrupted research labs, frequently ending carefully designed studies and upending the training of future scientists. We learn how medical discoveries are developed and tested, how research leads to medical advances and dispels false beliefs, and how young scientists’ lab experience prepares them for their careers. Medical research is absolutely necessary for the protection of our health.
