X-rays in 3-D show nanosized details

High-resolution microscope technique exposes a material’s insides

A new X-ray microscope technique gives a super-detailed look inside small samples, and does it in 3-D.

NEW VIEW A new X-ray microscopy technique reveals fine details inside a bone sample, such as holes housing bone cells. A detector measures changes in X-rays (depicted by colored dots, left) to create 2-D pictures that are combined into one 3-D image.
