In this week's Nature, Heidi Ledford takes a look at what she calls "the 24/7 lab," one that is "renowned for [its] intense work ethic and long hours." In her article, Ledford discusses the types of researchers "who are drawn to these environments," details "what it is really like to work there," and considers "whether long hours lead to more or better science." Overall, Ledford says that researchers who thrive in such environments are generally attracted to the autonomy and freedom they afford.
