Fluorite - Mt Blanc Massif, Chamonix, Haute-Savoie, Rhone-Alpes, France
"Fine partly transparent to translucent pink octahedral fluorite crystal measuring 2.8 cm across set nicely on matrix. In excellent condition damage-wise and quite pretty. Size: 5.0 x 3.1 x 2.0 cm. Ref: The Mineralogical Record: 41: 35-49. Ex Lloyd Tate collection."
"The locust borer beetle is native to North America. It attacks only black locust trees of the genus Robinia, which originally grew only in the Allegheny and Ozark mountain regions. Due to its ability to thrive in poor soils, the black locust has been widely used as a shade tree and in reclaiming land damaged by farming and strip mining. The locust borer beetle has extended its range as a result. It is now found over most of the U.S. and southern Canada. This is one magnificent insect - about 1" long, stately and impressive. I'd never seen one before I stumbled across this guy. The whole time I was shooting, I was saying, "What the hell is this thing!? What a COOL bug!" (Yes, I frequently talk to myself and my subjects when photographing them. Passersby must think me crazy).
Locust borer larvae tunnel into a tree's trunk and branches, weakening the tree and making it susceptible to wind breakage. The damage from borer tunneling and wind breakage often results in deformed trees or clumps of sprout growth."
"Two spiral arms emerge from the gas-rich disk around SAO 206462, a young star in the constellation Lupus. This image, acquired by the Subaru Telescope and its HiCIAO instrument, is the first to show spiral arms in a circumstellar disk. The disk itself is some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system.
This recent discovery of a star with spiral arms startled researchers using the Subaru telescope in Hawaii. SAO 206462 is more than four hundred light years from Earth in the constellation Lupus, the wolf."
