Flow Mastersby Michael Keller

Over the last decade, materials scientists have been trying really hard to keep from getting wet. To that end, they’ve made huge strides developing coatings that so thoroughly repel dirt and water, they seem almost magic. Their secret? Recreating the nanoscale structures that some organisms employ to stay clean and dry and to redirect liquid flow.

Among researchers’ muses from the natural world are the stenocara beetle, lotus and nasturtium leaves, and the wings of butterflies. The National Science Foundation has compiled some compelling visual examples of natural and synthesized superhydrophobic surfaces. See the full video below.

Interesting story…but what???

Colombian grad student faces jail for sharing a thesis onlineDiego Gómez Hoyos, a Colombian biologist studying for a master’s degree in conservation and wildlife management, faces up to 8 years in prison for posting a copy of another scientist’s thesis online. Colombia, like many other countries, grants strong protections to authors. In 2006, its law was revised to bring it into agreement with a free trade agreement with the United States, lengthening jail times and increasing fines.

“What worries our community is how a relationship of colleagues turned into a tremendous legal affair, with these horrible consequences,” writes Ángela Suárez-Mayorga of the University of the Andes in Bogotá, to

ScienceInsider in an e-mail. “Nobody believes that Gómez should go to jail for sharing a document.”

Revolutionary Telescope Gets Green LightAn 82-foot telescope boasting ten times the resolution of the Hubble Space Telescope has successfully passed design reviews and is ready to be constructed.

The Giant Magellan Telescope will use a light-collecting mirror surface more than six times the area of current instruments to hunt for distant, potentially habitable planets and let astronomers time travel back to a billion years after the Big Bang.

Despite Appearances, this creature, the

Wolf Eel, is one of the natural worlds true wonders - they are remarkably friendly.Wolf eels having never seen a human diver before will not fear it, not attack it, but investigate and most likely come to the conclusion that this human can help scratch its back.

They are the worlds friendliest animals!

Taylor Series ApproximationsA Taylor series is a way to represent a function in terms of polynomials. Since polynomials are usually much easier to work with than complicated functions, Taylor series have numerous applications in both math and physics.

There are many equations in physics — like the one describing the motion of a pendulum — that are

impossibleto solve in terms of elementary functions. “Approximations using the first few terms of a Taylor series can make [these] otherwise unsolvable problems” solvable for a restricted area of interest [1].The GIF above shows the five-term Taylor series approximation of a sine wave about
