Nature was cool enough to endow squid and octopi with measures to change their colors to hide from predators. They do it through sensitive pigment and light reflecting cells called chromatophores. Now, add a dash of modern science and hip hop as the stimuli for these cells and you'll get to see an squid light show that could blow your mind.
It's a momentous occasion for cephalopods everywhere as the first ever squid in space is now, uh, in space. The celebration will be short lived, however, as NASA plans to have the astronauts about Endeavour kill the squid in just a matter of hours, before it can break out of its tube of seawater and turn the battle lasers of the ISS on us. Or something.
Who would have thunk that the secret to invisibility might be within that of the multi-armed squid? The U.S. Navy is pumping $5 million into a team of scientists at Duke University over the next five years to see if they can tap into the squid's special "light sensitive organs" for use on the battlefield.
