Why do people get addicted to cigarettes? Should people use nicotine as a stimulant (without smoking it, of course)? What percent of people have a hard time quitting smoking once they start? What genetic factors predispose a person to nicotine addiction? How addictive is alcohol relative to nicotine? Is vaping less addictive and/or less negatively impactful on cardiovascular health than smoking? How can we train scientists to be better leaders? How valuable are graduate students to their advisors, mentors, and departments in various fields? How can researchers tell better stories about the data they've collected? Why are there fewer girls and women in science? Why can educators do to encourage more girls and women to work in scientific fields? Will increasing diversity in science improve science?
