In the 1990s, a button-pushing New York artist took on a subject that cut him to the quick: HIV and AIDS.
Barton Benes had lost a lot of friends, including his boyfriend, and was himself HIV-positive when an everyday kitchen accident took on a surreal bent -- one that got ...
On certain nights, as helicopters settle on the sandy ground in Afghanistan, the air mysteriously bursts into loops of light that trace the path of the helicopter blades; no one's sure what causes this; no one knows what to call these dazzling light displays — but a war photographer has given them a name — and thereby hangs a tale.
If I say "meet me 28 miles from here," that doesn't seem very far, right? But what if the 28 miles is not on a road or a highway, but straight up? Take a trip with a space shuttle solid rocket booster as it tumbles back to Earth. Headphones on.
