suzimoses, I learn that scientists have created mouse-human hybrids...well OK, the only hybrid part is a set of genes coding for human-type trichromatic color vision, otherwise they are mice.
Carl Zimmer's blog The Loom (syndicated at
carlzimmer) contains an interesting discussion of the result - the mice's brains can actually interpret what they are seeing, even though their brains aren't specifically designed to interpret the extra color information.
