Optical microscopes can be adapted to measure the mass of individual cells.

Measurements with live retinal rod cells reveal their capacity for detecting the statistical properties of different light sources.

A new method of imaging with second harmonic light allows more general studies of molecules with different orientations.

An alternative to a needle for penetrating cells may be found in the precise and forceful fluid jet created by two bubbles expanding and collapsing in tandem.

The answer to why the wings of certain butterflies diffract light in a reverse rainbow spectrum is found in the structure of the wing scales.

Simulations suggest that a set of cells in the eye can act like optical fibers to guide light through obscuring layers to the cells that detect light.

A film of bacterial protein can slow the speed of light to less than a tenth of a millimeter per second.

A new imaging technique provides nanometer-scale resolution by using light to sense molecular vibrations.
