Brandeis University researchers have created an organic gel that, despite being lifeless, seems to move of its own volition. While the movements are too small to be seen with the naked eye, when viewed under a microscope, microtubules in the gel flow of their own accord, moving like living cells viewed on a slide. You can take a look at the surprisingly soothing motion of this groundbreaking goo after the break.
Taking turns seems like an easy enough concept (though lets be honest, it's not.) But for the thousands of Emperor Penguins (Aptenodytes forsteri) that call Antarctica's vast ice sheets home, taking turns to stay warm is a highly complex affair.
A team of researchers, led in part by scientists from the Department of Physics at the University of Erlangen-Nuremberg in Germany, set up a time lapse camera to track the movements of a pack of penguins near the Neumayer Antarctic Research Station. When sped up, the video showed subtle movements that hadn't been noticed through observation of the pack with the naked eye. The penguins, in their own way, do a version of the wave with coordinated movements that radiate through the group.
