Just finished this one - the toes of Geckos have millions of these tiny spatula-tipped hairs called setae which is what allows them to stick to and climb almost any surface with ease. It's all due to what scientists call "van der Walls" forces which create a kind of electromagnetic pull on an object... it's all to do with how densely packed and teeney tiny the little hair things (setae) on thier feet are.
Cant stop watching the Science Network and TED talks... so I use sketching as an excuse. Here's a couple. The first two are from a video on the Science Network called "Robots and the Illusion of free will" apparently some recent findings in neuroscience have created a large debate about whether we have free will at all - namely because in controlled experiments it's been shown that our neurons are firing impulses that drive certain actions (like whether to push the red button or blue button) before we're even aware of having made the decision. Craziness. The other one is a pretty rough take on Noam Chomsky - the video quality wasn't the greatest, and the speech I was watching was really discipline-specific and kind of lackluster, which maybe led to me be less enthused about the drawing process itself.
It's been a little while since I've updated, so I figured I'd toss something up - finished this one a while ago - it's about some of the dangers facing the Indian Elephant, namely deforestation and of course poachers. My thought here was to make it look like there were peices missing from the picture, and use that to convey the concept.
