The spectrum of a frequency comb, commonly generated by a mode-locked femtosecond laser, consists of several hundred thousand precisely evenly spaced spectral lines. Such laser frequency combs have revolutionized the art of measuring the frequency of....

Eric Betzig shared the 2014 Chemistry Nobel prize with fellow American William E. Moerner and Romanian-German Stefan W. Hell for revolutionising science through the development of super-resolved fluorescence to exceed the accepted limits of tradition....

It has been a hundred years since molecules were first visualized directly by using x-ray crystallography. That gave us our first look at molecules as simple as common salt to one as complex as the ribosome that has almost a million atoms. In the las....

Throughout the 20th century it was widely accepted that a light microscope relying on conventional optical lenses cannot discern details that are much finer than about half the wavelength of light (200-400 nm), due to diffraction. However, in the 199....

Biological research and medicine were transformed by the invention and improvement of the optical microscope. Since the early 1990s, there has been another revolution in optical imaging, and manipulation of individual biological molecules and bio-mo....

Crystallography has been one of the mature sciences.  Over the years, the modern science of crystallography that started by experimenting with x-ray diffraction from crystals in 1912 has developed a major paradigm Ð that all crystals are ordered an....
