Invisibility cloaks: Out of science fiction and into reality

iStock_000042489660LargeInvisibility cloaks are becoming one step closer to reality, thanks to cephalopods. Octopuses, squid, and cuttlefish have the ability to change the color and texture of their skin to match their surroundings, and by studying these animals, researchers at MIT and Duke University have created a material that can change color and texture on demand.

In cephalopods, muscle contractions change the shapes of pigment sacs and skin texture into a large variety of colors and patterns. This new octopus-inspired material works by using voltage changes to activate molecules in the elastomer. Essentially, you’d use a remote control to change color and texture. When you turn it off, it returns to its original state. Watch the video in the link here.

Besides being very popular with Harry Potter fans, this technology is really important. A system that can modify its camouflage with a touch of a button could be extremely useful, and even life-saving. Researchers are interested in developing anti-fouling coating for ships, and military camouflage could be revolutionized. Can you think of other applications where changing the texture or color of an object could be useful? Post your ideas in the comments below!

Octopuses are awesome. See why…

Not only can they camouflage themselves by changing colors and imitating other animals to blend into their surroundings, but they can teach researchers about the brain’s ability to store and recall memories. Studying the octopus has led to new understanding of linguistics (ever wonder what an octopus and your tongue have in common?), and the venom from some species of octopus has been important in the understanding of new opportunities in drug development. And their arms can detach, taste whatever they’re touching, and also act like penises.

Intrigued? I think I’ve found the ultimate octopus video that proves how much octopuses kick ass. I promise, watch this one, you won’t be sorry. And if you don’t laugh, you may want to have yourself checked out. Click here to watch it.

We can learn a lot from animals, and sometimes, a little bit of humor is all it takes to get people to remember that! And there’s no doubt: octopuses kick ass.
