bitchville: Incredibly Colourful Magnified Grains of Sand Viewed at an astounding magnification of over 250 times, tiny grains of sand are surprisingly colorful and extremely unique. Each piece is either a fragment of crystals, spiral fragments of shells or crumbs of volcanic rock. To see these incredible images, Dr. Gary Greenberg goes through a painstakingly lengthy process. First he takes many photos from different points of focus. Then, he combines them using software to produce one spectacular image. “It is incredible to think when you are walking on the beach you are standing on these tiny treasures,” says Greenberg.” via http://sandgrains.com/ and ISI

Diatoms: The Evolution Of A New Species

Richard Dawkins explains how microscopic algae called Diatoms uniquely evolved in Yellowstone Lake.

During Richard Dawkins’ 2009 American tour, we visited Judy Diamond’s “Explore Evolution” exhibit at the University of Nebraska State Museum in Lincoln. This exhibit has now been replicated in six museums around the country. While visiting we filmed a collection of short unrehearsed and unscripted videos—just inspired by the “Explore Evolution” exhibit.

See the “Explore Evolution” web page here:

cwnl: One of life’s greatest questions finally answered: What came first, the chicken or the egg? “It had long been suspected that the egg came first but now we have the scientific proof that shows that in fact the chicken came first.” It turns out there’s a protein, ovocledidin-17 (OC-17), that’s only found in the ovaries of chickens that is crucial to the formation of an egg’s shell. OC-17 coverts calcium carbonate into calcite crystals, which in turn form the shell. No OC-17, no shell, and since OC-17 is only found in chicken ovaries, the chicken had to have come first.
