Water without windows: Capturing water vapor inside an electron microscope
(PHYSorg.com Physics)

The inside of an electron microscope, which requires vacuum levels similar to those encountered in outer space, can be an extremely inhospitable place for organic materials. Traditionally, life scientists have circumvented this problem by freezing their specimens so that that they can be safely loaded into a microscope. Now, researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have devised a new approach to imaging organic compounds.
