Thomas Edison famously said that genius is 1 percent inspiration and 99 percent perspiration — words that could well apply to a new machine promoted by UNICEF that turns human sweat into drinking water.
The Sweat Machine extracts moisture from worn clothes by spinning and heating them, then filters the resulting liquid so that only pure water remains. It was built by Swedish engineer and TV personality Andreas Hammar, and uses a technology developed by Sweden's Royal Institute of Technology and the water purification company HVR.

Fish oil may have some benefit for the heart. But a study in the Journal of the National Cancer Institute links higher blood levels of the omega-3 fatty acids in fish oil to a higher risk of prostate cancer. Study author Alan Kristal says the potential mechanism is unclear, but he warns that supplements can sometimes increase the risk of the very diseases they're meant to prevent.
Astronomers have detected a previously unseen moon orbiting Neptune, bringing the planet's moon count to 14. Mark Showalter, an astronomer at the SETI Institute, describes how he spotted the 12-mile moon while combing through old images taken by the Hubble Space Telescope.
Researchers at the University of Puerto Rico have developed a system that can automatically record and analyze sound clips from the field. Mitch Aide, lead researcher on the project, describes how the system can improve biodiversity monitoring.
In 2009, Alaska's Redoubt volcano erupted and sent plumes of ash miles into the air. But underground, there was even more activity. In a study published in Nature Geoscience, researchers say the volcano experienced a large number of pre-eruption earthquakes that created a "scream."
In the penultimate edition of the podcast, NPR's Ken Rudin and Ron Elving summarize the political fallout of the Zimmerman verdict and the Senate deal reached on filibusters and also update the latest on the Wyoming and Montana Senate races. They also try to define the word "penultimate."

Around the world, hundreds of millions of Muslims are fasting from sunrise to sunset. The Muslim holy month of Ramadan began last week and continues until Aug. 7. That's 30 days of avoiding food and drink all day. But in many families, someone still has to prepare a hearty, and sometimes festive, dinner every night.
"Ramadan is a big change in routine," says Jehad Outteneh, a Palestinian in Jerusalem who shops and cooks for her family of eight.
U.S. Secretary of State John Kerry announced a last-minute trip to the West Bank this morning that's intended to jump-start stalled peace talks between Israelis and Palestinians.
The trip comes just hours after the Palestinians said they would not return to the negotiating table unless Israel agreed to begin talks using the borders that existed before 1967, when Israel captured the West Bank, Gaza Strip and east Jerusalem.
Good morning. I'm Renee Montagne. Even if you have been bored watching paint dry or grass grow or water boil, you have nothing on these scientists. An experiment that began in 1944 at Trinity College in Ireland just now has a definitive result - to test whether a thick substance called pitch flowed and dripped. A funnel with the stuff was placed over a jar. Seventy years later students saw a drip forming, set up a camera, and witnessed the drip drop. It's MORNING EDITION.
