A local resident entertains visitors to the Kawah Kamojang geothermal field in West Java. He puts a length of bamboo to the steam coming from the ground to make a whistle, then throws soda cans into the vent, which shoots them high into the air.

While doctors and researchers put enormous efforts into developing new treatments, one group of veterans in Salt Lake City is finding relief in a very old tradition: a Native American sweat lodge.
