Inspired from Mother Nature: The body of the brittlestar Ophiocoma wendtii is studded with tiny crystalline lenses made of calcium carbonate. Microlenses like these are of great interest technologically, yet they have always been extremely expensive to produce. However, scientists from the Max Planck Institute of Colloids and Interfaces and colleagues from other institutes took their cue from biology and came up with a relatively simple and inexpensive method of producing calcium carbonate lenses packed together in a regular arrangement.

A variety of imaging technologies rely on light with short wavelengths because it allows very small structures to be resolved. However, light sources which produce short, extreme ultraviolet or x-ray wavelengths often have unstable emission wavelength and timing.

When accidents that involve traumatic brain injuries occur, a speedy diagnosis followed by the proper treatment can mean the difference between life and death.
