• A change is in the air. The Fortune staff is starting in on our third annual Change the World list , which highlights companies that have made measurable progress addressing global social problems as part of their core business strategy. Among the companies we recognized last year: Salesforce, for closing its gender pay gap, and The Gap, for empowering its garment workers—most of whom are women—with life skills training. If you'd like to nominate a company for the list, please email Fortune senior writer Erika Fry (erika_fry@fortune.com) with a brief description of why it should be considered. You can also submit nominations (and learn more about the criteria) through the application portal here. • Margrethe vs. Goliath. While you were sleeping, European antitrust officials fined Google about $2.7 billion for unfairly favoring some of its own search services over those of rivals.

New York Times • An open secret.

Fortune • What's up with the docs? After three female Mayo Clinic doctors noticed they were frequently introduced at conferences by their first names—while their male colleagues were usually called "Doctor"—they decided to do a study to see how common the phenomenon is. Here's what they found after looking at videos of 321 speaker intros: Male introducers used professional titles for female doctors 49% of the time on first reference, but introduced male doctors by their titles 72% of the time. Washington Post • Not one drug fits all. In more medical news, a study out of the U.K. finds that research labs may be short-changing women by ignoring differences between male and female animals in experiments to discover new drugs. Looking at mice of both sexes, scientists found that gender differences could impact results in more than half of their experiments.
