British chemist Humphry Davy once said that “nothing is so fatal to the progress of the human mind as to suppose that our views of science are ultimate … that there are no new worlds to conquer.” In that spirit, Science takes a look at trends and ideas that preoccupied the scientific community last year—and makes some guesses at what new themes are likely to take hold in 2015.
