Bees and Flowers
I don't know how many of you knew about this, so I figured i'd show you something cool. Humans have decent eyesight (well most of us do), but our vision encompasses just a tiny slice of the electromagnetic spectrum. We can't see ultraviolet or X rays, and we can't see infrared, microwaves, or radiowaves. When we look at a yellow flower, all we see is yellow. Bees can see into the ultraviolet spectrum, and many species of flowering plants have flowers with patterns only visible in UV. The leading theory is that these patterns serve to help guide bees to them.
