Electron microscopes are amazing tools for getting detailed closeups of the things inside a cell that make it go, but when it comes to putting those things in the context of a whole organism, they're not such a great tool. A team at the University of Leden in the Netherlands
is helping microscope users focus on the bigger picture. They've created a nearly complete atlas of a zebrafish embryo that researchers can navigate
by zooming in and out through various levels of detail -- just like Google Earth
, except with the inside of a baby fish.
