X ray microscopy is providing unique insights into the cycling of carbon in the environment, and the role of metals in cells. All of this stems from the very different interactions of X rays with matter compared to visible light interactions, and with faster-than-Moore's law increases in the brightness of x-ray sources. After a review of the basic physics, recent developments in x-ray nanofocusing and on applications in biology and environmental science are highlighted.
