Our panel of editors reviewed more than 160 research summaries from scientists all over the globe. They selected for publication 30 stories that they felt most clearly communicated breakthroughs of interest to the optics community. Some of the summaries have related multimedia. Thanks to all who submitted summaries, as well as to our panel of guest editors: Robert D. Guenther, the panel chair, and guest editors Mihaela Dinu, Dmitry Dylov, Alexandre Fong, Andrew Forbes, Nicholas J. Frigo, G. Groot Gregory, Brooke Hester, Bob Jopson, Nick Lambert, Arlene Smith, Yanina Shevchenko, Zuleykhan Tomova and Stephen R. Wilk.
