Call for pitches: Nature, geology, flora, fauna, glaciers, fossils! I’ve just taken over Discover Magazine’s Planet Earth column, which means I’m in need of your ~1200-word stories exploring any topic from “the field.” Discover delivers entertaining, relevant, and thought-provoking science content that feeds the mind and fuels the imagination. The magazine is aimed at the general public, covering topics ranging from global warming and black holes to Neanderthals and robots. Before applying, review submission guidelines. Email all questions and submissions to Marisa Sloan, Assistant Editor at Discover Magazine, at: msloan@discovermagazine.com.
