Bright lights are part of a city's ecosystem. Think of Times Square or the Las Vegas Strip or right outside your bedroom window.
Electric lighting is ubiquitous in most urban and suburban neighborhoods. It's something most people take for granted, but appreciate, since it feels like well-lit streets keep us safer. But what if all this wattage is actually causing harm?
"We're getting brighter and brighter and brighter," warns Paul Bogard, author of the upcoming book, End of Night: Searching for Natural Darkness in an Age of Artificial Light.
Margaret Bonds, who died in 1972, is perhaps near the top of the very short list of African-American female composers. Thanks to her partnerships with Langston Hughes and soprano Leontyne Price and others, she's remembered in some circles as an important figure in American composition. But, mostly, she's been forgotten.
"It's amazing that people don't know who she was, although she was quite well known in her time," says Louise Toppin, an opera singer and a voice professor at the University of North Carolina at Chapel Hill.
