JoVE also publishes Science Education collections aimed at instructing scientists in fundamental concepts and methods in a range of fields including biology, chemistry, physics, psychology, and practical subjects like laboratory safety, cell culturing, and care of "Drosophila" flies. Some experiments can be difficult to replicate if they involve techniques that are unfamiliar or unusually sensitive, and a short written description of the original scientific methods might not be sufficient. "JoVE" videos are a step-by-step visual guide of the actual experiment so that the minute hand movements and other
