This is TELL ME MORE from NPR News. I'm Michel Martin. Our coverage of the George Zimmerman trial verdict drew many strong reactions. Coming up, we will hear some of them. We'll dig into listener e-mail and comments in BackTalk. But first, it's time for Faith Matters. That's where we talk about matters of faith and spirituality in times of crisis, whether personal or involving the country. Many people in this country turn to faith for comfort or understanding.
Two recent eruptions on the sun sent solar tsunamis sweeping across its surface. Physicist David Long reported on the tsunamis in the journal Solar Physics, and he says the waves allowed him to calculate the magnetic field of a "quiet" area on the solar surface, which is 10 times weaker than a fridge magnet.
If you can't get to a beach this weekend, you can still see waves. Just look up.
Clouds, after all, are sculpted by waves of air. These clouds, in Birmingham, Ala., were formed when two layers of air — one fast, the other slow — collided at just the right speed to create rises and dips that caused the clouds to curl in on themselves and crash, just like waves on a beach.
Photographer Kirk Crippens says you can't. But that hasn't stopped him from trying. Since 2009, he has been documenting the city of Stockton, Calif., which last year became the largest city in American history to file for bankruptcy — until Detroit filed yesterday. Before bankruptcy, Stockton was the epicenter of the foreclosure crisis. But before that, Crippens says, it "was an all-American city — Boomtown, USA — housing going up everywhere."
With each season of AMC's Breaking Bad, Dean Norris' character, DEA agent Hank Schrader, has evolved from a knuckleheaded jock into a complex, sympathetic and even heroic counterpoint to the show's anti-hero, high-school chemistry teacher turned meth cook Walter White. And to further complicate matters, Schrader and White (played by Bryan Cranston) are brothers-in-law.

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.
Ever tried to make your own sunscreen? A water bottle rocket? How about a cardboard canoe? Eric Wilhelm, founder of Instructables, and Mike Szczys, managing editor at Hackaday.com, discuss their favorite do-it-yourself summer projects. And Bon Appetit's Andrew Knowlton suggests some cooking hacks, like "cooler corn" and turning your BBQ into a smoker.
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."
