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. The Dutch colonial government drilled Indonesia's first geothermal wells at Kamojang in 1926, when the country was still known as the Dutch East Indies.

Geysers puffing steam and bubbling, sulfurous hot springs are plentiful in the Kawah Kamojang geothermal field in West Java. The field is located in a caldera, the crater of a volcano that has erupted and collapsed.
Indonesia, the country with the world's largest number of active volcanoes, is betting that all the hot rocks will provide a clean and reliable energy source for the future.
The country is believed have 40 percent of the world's geothermal energy resources. But making geothermal energy economically feasible will require adjusting the country's heavily subsidized energy prices. And that issue is a political hot potato.
Forget the calendar. With The Avengers, Battleship, and Men In Black already battling aliens at the multiplex, Hollywood's summer has arguably been under way for weeks.
No doubt, the tent-pole blockbusters — Ridley Scott's Prometheus, The Amazing Spider-Man, The Bourne Legacy, and the rest — will offer plenty of entertainment value, but there are a couple of hardy, resourceful little girls you might want to attend to, too.
Substance abuse. Violence. Even thoughts of suicide. These are some of the problems that many veterans returning home from the wars in Iraq and Afghanistan are struggling with.
Today it's called post-traumatic stress disorder, or PTSD, but it has affected veterans going back much farther. 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.
Let's turn to another story we've been following in recent weeks: African-Americans and same-sex marriage. When President Obama came out in support of gay marriage, some African-American religious leaders protested. But according to new polling data, African-Americans are no less supportive or, for that matter, opposed to gay marriage than any other group in the country.
Every few weeks on the program, we've been running an occasional series called Why Music Matters, where we bring you the stories of music fans in their own words, about how certain songs or even bands have changed their lives. Today's story comes from a young artist in Seattle. Her name is Vivi Perez, and she almost gave up on high school, that is until a community activist group called El Centro de la Raza introduced her to the music business.
VIVI PEREZ: I felt kind of, like, I didn't know where I was going a lot in high school.
We hear from veterans about their memories of those who died in combat. Stories are from Jill Knappenberger, who served in the American Red Cross during World War II; former Nebraska Sen. Chuck Hagel, a Vietnam veteran; and Butch Bracknell, an Afghanistan and Iraq serviceman.
The Associated Press recently reported on the growing numbers of veterans filing new disability claims after returning from war. Close to one out of two veterans who've served in Iraq or Afghanistan have now filed disability claims for service-related injuries — more than double the rate of previous wars. Marilynn Marchione of the AP offers her insight.
