Six for Science

Here we go:
1. Ice clouds on Mars are kind of weird.
2. Old ice in the Arctic is almost gone.
3. Old North America gets less natural every year.
4. Ba Ba Black Sheep have you any wool? No sir, no sir, because I no longer breed true.
5. Ant berries
6. Finally, video contacts

Yes, this image is of a rabbit wearing experimental contact lenses. Don't worry, I'm sure she will still make a fine hat.
