gip and today's cool thing that scientists got to do

[firecat]

Via 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.

Also it contains an image I couldn't resist iconifying.

Thanks for the link - that is pretty cool. (Aside: before reading it, I winced, thinking "What are they doing to the poor mice now?" I'm a bit squicked by people creating phosphorescent rabbits, and so forth. But it doesn't appear that any harm has been done to these mice.)

One of the comments intrigued me, where the commenter asks if, due to the fact that trichromatic vision has been gained and lost throughout vertebrate and mammalian evolution, our brains have collectively preserved the ability to process it, so when the mice were bred for tricolor vision, presto, their brains switched on to process the three color channels? Makes you wonder what other potential capabilities our brains have, that we lack sensory organs to activate?

Yeah! I vote that they inject some reptile or bee genes into some humans to find out...

(...and then we could make an entirely different movie called "Killer Bees"...)

Are you volulnteering? :) (I know, you'll wait until they inject whisker and tail genes into humans before volunteering. :))

What's "gip", by the way?

I think that the genes have to be injected before birth, otherwise I wouldn't mind volunteering. Just think, night vision without the need for those expensive goggles!
