Iris of the eye, SEM

Iris of the eye. Coloured scanning electron micrograph (SEM) of the inner surfaces of the iris and adjoining structures in the human eye. At far right (blue) is the edge of the pupil, the hole that allows light into the eye. Coloured mauve is the iris which controls the size of the pupil and therefore how much light will enter. The band of folds down the centre (red) are the ciliary processes. These secrete fluids that nourish neighbouring parts of the eye. They are also the sites of attachment for the long, thin zonule filaments (yellow and green) which are responsible for suspending the lens (unseen). Magnification: unknown

China-School-Education-Population

In a picture taken on January 21, 2015, children dressed in uniform sing after raising the national flag at the Beichuan Red army elementary school in Beichuan, southwest China's Sichuan province. China's push to encourage more couples to have a second child after decades of restrictive family planning policies has fallen short of expectations in the first year, state media reported in January. The world's most populous country has restricted most families to a single child since the late 1970s, but the Communist Party has started easing controls, allowing couples to have two offspring so long as one of the parents is an only child, rather than both.
