All aboard! In the May issue of Discover, you'll check in with a team of engineers designing a plasma rocket that could taxi humans to Mars in under 40 days. Back on Earth, a gruesome facial cancer is threatening populations of Tasmanian devils, and it could destabilize an entire ecosystem. You'll also see how Mother Nature is exposing New York City's ecological weaknesses. 

This month's issue also features a bearded woman's medical mystery, nocturnal "vampire steroids" and one man's simple plan to feed the world. So dig in! There's more than enough to satiate your science appetite in May.
