Sci-fi movies have shown us what it might be like to shrink down to the size of an ant, or to blow a grasshopper up to the size of a skyscraper. And while a shrink ray may never be a scientific reality, a team led by MIT’s Edward Boyden has actually found a way to expand biological tissue to several times its original size – giving researchers a more detailed look than ever at microscopic structures within the body.
