several versions of a crystal — one pure crystal and several others in which the crystallized mole­ cule is soaked in, or "doped" with, a different heavy metal, like mercury, platinum, or uranium. Because these heavy metal atoms contain many electrons, they scatter X-rays more than do the smaller, lighter atoms found in biological molecules.

Electron microscope - Wikipedia

An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved ...

A Dynamic Optical Signal in a Nocturnal Moth: Current Biology

Butterflies often produce wing colors that can switch on/off with viewing angle, but Kelley et al. report a nocturnal moth with patterns that change in shape and position with viewing angle. These effects are generated using specialized mirror-like nanostructures, yielding dynamic patterns that may facilitate signaling in dim light.
