Watson and Crick saw the structure of DNA in a spiral staircase, and Newton understood gravity in the falling of an apple—but all human beings regularly experience flashes of inspiration, seemingly out of nowhere. Insight researchers want to know more about the nature of the so-called ‘a-ha moment’, so they are setting us a citizen science challenge. Find out what they know already, and how you can contribute to the science of creativity. And we hear from a neuroscientist whose recent research shows that the most creative people have superior connectivity between three distinct brain regions.
