Today we continue our series Single Best, where we ask top science writers and editors to give us their single best piece of advice, given or taken; or their single best idea, reporting trip or memorable experience. Here, longtime science journalist and author Dan Ferber talks about the detective skills needed to spin a good science yarn. After many years of freelancing for publications such as Science, Reader’s Digest, HHMI Bulletin, and others. Ferber is now a science writer for Harvard University’s Wyss Institute for Biologically Inspired Engineering. He is also the co-author of Changing Planet, Changing Health: How the Climate Crisis Threatens our Health and What We Can Do About It. Follow him on Twitter @danferber.
