Flower of the chickweed

False-colour scanning electron micrograph of the flower of common chickweed, Stellaria media, a self- pollinating plant found on uncultivated ground in Europe. In the background are the five sepals or calyx (green), which serve a protective function. Next are the 5 notched petals or corolla (yellow), which attract insects by their bright colour. Calyx & corolla together form the perianth. Three stamens topped by pollen-bearing anthers (male organs) lie between the petals & the capsule. At centre are the tufts of the stigmas (female organs) supported on stalks called styles. These connect the pollen-receiving stigmas with the ovary. Magnification: x5 at 6x4.5cm size

Ussr-Russia-History-Coup-1991

River ships moor in front the Russian White House in Moscow on August 21, 1991, to support Boris Yeltsin. Russia marks on August 19-22, 2011, the 20th anniversary of the abortive 1991 coup against then Soviet president Mikhail Gorbachev. Tanks rolled through Moscow towards the Russian White House, where Boris Yeltsin, leader of the Soviet-era Russian republic at the time, gathered his supporters after denouncing the coup from the roof of a tank, what resulted later a collapse of the Soviet empire.
