Nature : That young scientists are generally considered to be at the forefront of new ideas in their fields is a widely held belief throughout the sciences. Now, Mikko Packalen of the University of Waterloo in Canada and Jay Bhattacharya of Stanford University and their colleagues have found proof to back that up. They wrote a computer program to look for the most commonly used 1-, 2-, and 3-word phrases in the titles and abstracts in the MEDLINE database of biomedical research. To determine which articles were the most innovative, they looked at when the terms first appeared. By calculating the ages of the contributing authors, the researchers found that scientists are significantly more likely to cite innovative ideas in the first 10–15 years of their career than they are later in life. They also found that the most innovative papers had an early-career first author and a mid-career last author. The numbers might shift somewhat depending on the particular field of study, or if the full text of the articles were analyzed.
