In 2009 the publisher notified collegiate libraries that yearly subscription prices for the magazine would increase by nearly 500% for print and 50% for online access to $1,500 yearly. In 2013, Danielle N. Lee, a female scientist who blogged at Scientific American, was called a "whore" in an email by an editor at the science website Biology Online after refusing to write professional content without compensation. When Lee, outraged about the email, wrote a rebuttal on her Scientific American blog, the editor-in-chief of Scientific American, Mariette DiChristina, removed the post. DiChristina cited legal reasons for removing the blog. The editor at Biology Online was fired after the incident. The controversy widened in the ensuing days. The magazine's blog editor, Bora Zivkovic, was the subject of allegations of sexual harassment by another blogger, Monica Byrne. Although the alleged incident had occurred about a year earlier, editor Mariette DiChristina informed readers that the incident had been investigated and resolved to Byrne's satisfaction.

He apologized to Byrne, and referred to the incident as "singular", stating that his behavior was not "engaged in before or since". Zivkovic resigned from the board of Science Online, the popular science blogging conference that he co-founded with Anton Zuiker. Following Zivkovic's admission, several female bloggers, including other bloggers for the magazine, wrote their own accounts, alleging additional incidents of sexual harassment, although none of these accounts were independently investigated. A day after these new revelations, Zivkovic resigned his position at Scientific American.
