LINDA WERTHEIMER, HOST:

Scientific research can be expensive, but a lack of funds did not stop one scientist in Buffalo from moving forward with his project. State University of New York professor Chris Lowry came up with a creative and cheap way to get measurements on stream levels across the state by crowdsourcing his research.

Chris Lowry joins us from member station WBFO in Buffalo, New York. Professor Lowry, thank you very much for coming in.

CHRIS LOWRY: Oh, thanks for having me.

More than a century after the invention of powered flight, birds are still teaching us something about how to fly airplanes, with the Air Force studying the V-shaped formation of airborne geese as a way to save fuel.

The technical term is "vortex surfing" and it's already well-known — NASCAR drivers and Tour de France cyclists use it to "draft" off competitors.

Eruptions on the Sun Set Off 'Solar Tsunamis'

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.

Just Like Van Gogh, Ocean Waves Paint Clouds In The Sky

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.

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: Too Much of a Good Thing?

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.
