Theorists have used string theory and nonperturbative objects known as D‐branes to count the quantum microstates of black holes. This major step forward in our understanding of quantum gravity may resolve the longstanding “paradox” of information loss in black hole evaporation.

Articles

Physics Today 50 (3), 27–32 (1997); https://doi.org/10.1063/1.881691

The next generation of data security systems may thwart counterfeiters and eavesdroppers by employing new systems and devices based on optical information processing.

Physics Today 50 (3), 34–40 (1997); https://doi.org/10.1063/1.881692

Nowadays we can intercept a spreading sound wave, time‐reverse it and send it back to the source. That should greatly enhance our ability to locate gallstones and submarines.

Physics Today 50 (3), 42–47 (1997); https://doi.org/10.1063/1.881752

Novel approaches to the creation of unusual electronic materials may result in more efficient thermoelectric refrigerators and power sources with no moving parts.
