In this undated photo made available by journal Nature on January 15, 2014, a northern bald ibis (Geronticus eremita) flies in Tuscany, Italy. A new study released Wednesday, January 15, 2014 says the birds choreograph the flapping of their wings, getting a boost from an updraft of air in the wake of the flapping wings by flying behind the first bird and off to the side. When a flock of birds take advantage of these aerodynamics, they form a V. (Photo by Markus Unsöld/AP Photo)

“Exactly one year before the long awaited Sochi Olympics, Vladimir Putin went to Sochi personally to see how the construction is going.

Good job”, and then fired the vice president of the Olympic committee. Russian artist Vasily Slonov painted his view of the upcoming games, giving a new interpretation to the adored Russian mascot Cheburashka, and combining officially endorsed stereotypes of Russia with grimmer and less accepted ones”. – Ruskie.info.
