Before most women know they're pregnant, an embryo has already begun organizing itself into the structures that will shape a developing body. Scientists have few opportunities to study those earliest stages of human development, making many of life's first steps difficult to obse
Before most women know they're pregnant, an embryo has already begun organizing itself into the structures that will shape a developing body. Scientists have few opportunities to study those earliest stages of human development, making many of life's first steps difficult to observe directly.

Scientists expected these Galápagos sea turtles to wander. They stayed put
Yellow-morph green sea turtles in the Galápagos surprised scientists by staying remarkably close to home instead of making the long journeys typically associated with sea turtles. Satellite tracking showed that none left the marine reserve during the study, revealing just how imp
