The development of the new method, which was reported January 10 on the Web site Science Express, drew on Baltimore's pioneering research in the genetic makeup of viruses. Baltimore is now the president of Caltech.
In the Caltech experiments, the researchers stripped anHIV virus of its disease-causing elements and used it to virally infect single-cell embryos of mice with a gene from a jellyfish.
Any number of different genes could have been selected. For the purpose of the studies, the researchers chose a specific jellyfish gene that could serve as a "marker" to indicate whether the gene transfer was successful. The gene produces a protein that gives the jellyfish a green fluorescence.
When the mice were born, they carried the jellyfish gene in their own genes. Under fluorescent light, all their major tissues and organs—including skin, bones, muscles, lungs, liver, kidney, stomach, brain, and retina—emitted a green glow.
The trait became a permanent feature of the mice's genome and was passed along to many of their offspring.
Some of the mice glowed more than others, depending on how many copies of the jellyfish gene they acquired. But 80 percent of the original mice (14 out of 17) that received the gene transfer carried at least one copy of the gene, and most of them, 90 percent, showed a high level of fluorescence.

That was awesome.
My question is:
Were they implying there at the end that it wasn't the octopus that was changing its form, it was the octopus that was changing the way we perceive its form?
What a bizarre creature.
I think they said after studying it frame by frame, they came to the conclusion we should be able to see it but we can't?
Even though they are colored blind, I think they were the first to develop complex eyes? I think they suggested that the octopus knows something a little more to objective reality, at least visually, than we do. It's goal isn't to simple blend in, but to take away any information that would reach the potential predator's eyes.
Other animals are good at camouflage, but it looks like the octopus is the master of disguise.
ETA: It's colored blind and takes it's cues from pattern recognition, but it somehow knows the colors around it to match perfectly right?, so perhaps that is what they meant at the end? It's picking up some kind of information someway, or distorting it... I'm at a loss for words on how to explain...edit on 13-9-2011 by AMANNAMEDQUEST because: (no reason given)
