EDITORIAL
Enabling the Future In the June editorial, I wrote about the US National Academies undertaking an update of its 1998 study, Harnessing Light: Optical Science and Engineering for the 21st Century. Now SPIE, the international society for optics and photonics, which pushed for a second study, has launched a blog, “Harnessing Minds,” to provide the photonics community with an open online forum to offer input...

LIGHT SPEED
From a cold start, Brazilian science and technology heat up In a country where basic educational needs have gone unmet for decades, you might not expect a thriving photonics industry. In Brazil, however, light-based efforts are steadily climbing toward prominence. As recently as the beginning of the century – this one, not the 19th or even the 20th – only half of Brazil’s children finished primary school, and 75 percent of adults were...

GREENLIGHT
Solar Power Without Semiconductors A magneto-optical effect that has been overlooked for more than 100 years may one day be harnessed to create semiconductor-free solar cells. It sounds implausible – using sunlight to generate an electric charge without the use of semiconductors, or, at the very least, metals. But professor Stephen C. Rand and graduate student William M. Fisher of the University of Michigan, Ann Arbor, claim...
