It will be a long experimental haul before the great potential of quantum effects can routinely be exploited for technological ends. A sense of practical purpose among researchers will encourage progress.

A commonly used blue dye is more than just a pretty colour. This material and its relatives are semiconductors, and their magnetic properties can be controlled by engineering their crystal structure.

The life-histories of pike adjust quickly to shifts in the opposing forces of fishing and natural selection. Such rapid changes suggest that evolutionary dynamics must be incorporated into fisheries management.
