This is a close up of a llama eye. The strange "ruffles" are called 'iridic granules' (corpora nigra) and they are used to to shade the eye from bright sunlight. In bright light these iridic granules can actually interlock to completely cover the centre of the pupil. This leaves just two holes open on either end of the pupil, reducing the amount of light that can enter the eye. These odd looking structures are also found in horses, cattle and sheep.

This is very cool: two planets have been found around the Sun-like star Kepler-62, both roughly the size as Earth (40% and 60% bigger, so in the same category as Earth), and both orbit the star at the right distance to allow liquid water on their surfaces!

It turns out that ants are capable of making career moves.

Computer tracking of ants shows that colonies have three main occupations: nursing the queen, cleaning, and foraging for food. Younger ants typically stay near the queen, but as they get older, they make the transition to foraging. This transition with regards to age was an exciting discovery, giving more insight into ant behavior.

The coelacanth is known as a “living fossil” because it looks very much like its ancestors from 300 million years ago. Its genome has been sequenced, and it, in fact, has been found to be evolving at a very slow rate. The genetic sequence also might help give some insight into the transition from fins to limbs.

Imagine a battery the size of the one in your cell phone with enough juice to jump-start a car. It's actually not too far-fetched. Scientists at the University of Illinois have been developing microbatteries. Only a few millimeters long, these batteries may pave the way for electronics to become smaller and thinner, while still providing enough energy to be highly effective. The best part is that it recharges 1000 times faster than current batteries. Good things do come in small packages Slight Smile [ ... ]
