With the technique of fluorescence microscopy single Rydberg atoms can be directly imaged. (sciencedaily.com)
Morphologically the majority of V + cells grown in the presence of LIF appear indistinguishable from their V − counterparts and the level of fluorescence in these morphologically normal V + cells is substantially lower than that observed in cells that either appear differentiated or have been differentiated in response to LIF withdrawal (Figure 2B).

The invention of lasers, a concentrated source of monochromatic and highly directional light, revolutionized photonics in the 1960s and brought us technological advancements such as bar code scanners, CD players, and, with fluorescence microscopes, the first taste of the power of biophotonics.
