That webpage serves as visual representation of the moment in time when there was exactly 7 billion people in existence, which was on October 31, 2011 at 5:49:16 GMT. It represents human beings as they relate to the planet earth, and all the philosophical and symbolic attributes that entails. Click over to 7 Billion World to find yourself. Each stick figure has a number on it, so you can see how far down the list you are as you are scrolling. All I can say is wow!

With its complex interweaving of symbols, structure, and meaning, human language stands apart from other forms of animal communication. But where did it come from? A new paper suggests that researchers look to bird songs and monkey calls to understand how human language might have evolved from simpler, preexisting abilities.

Immune cells are like the Hatfields and McCoys of our bodies--once wronged, they never, ever forget. This is how we gain immunity, and it’s why vaccines work: Immune cells develop a memory of an invading pathogen, and they build an alert system to find and fight it should it ever return. But a new study by Stanford researchers adds a new wrinkle to this long-held immune theory. It turns out immune cells can develop this memory-like state even for pathogens they’ve never met. This may come from exposure to harmless microbes -- or the memories may actually be borrowed from other, more experienced cells.

This eight second video is extracted from a set of test recordings that have been collected within the Auroral Acoustics project (2000-2012). During this time period high-quality audio recordings were made during approximately 100 geomagnetically opportune nights at different locations in Finland. These recordings form a database that is half a terabyte in size. This short clip has been selected from some video recording experiments that were performed during some nights simultaneously and independently of the main activities

Unbelievable these tiny little devils. Whatever we forget on the kitchen table, these guys take it. Now we tried it with a dead gecko we found in garden and an observation camera. Looks like time is money for this little workers and Geico needs a new mascot to tell you how much money you can save with their insurance. With this spirit, we would get rich in no time. This is really crazy.

In a paper published in the January 8 print edition of the Proceedings of the National Academy of Sciences, the research team demonstrates that a synthetic system can reconfigure itself through a combination of chemical communication and interaction with light. Balazs and her team developed a 3D gel model to test the effects of the chemical signaling and light on the material. They found that when the gel pieces were moved far apart, they would automatically come back together, exhibiting autochemotaxis—the ability to both emit and sense a chemical, and move in response to that signal. “This study demonstrates the ability of a synthetic material to actually ‘talk to itself’ and follow out a given action or command, similar to such biological species as amoeba and termites,” says Balazs.

Human collective behavior can vary from calm to panicked depending on social context. Using videos publicly available online, we study the highly energized collective motion of attendees at heavy metal concerts. We find these extreme social gatherings generate similarly extreme behaviors: a disordered gas-like state called a mosh pit and an ordered vortex-like state called a circle pit. Both phenomena are reproduced in flocking simulations demonstrating that human collective behavior is consistent with the predictions of simplified models.

One consequence of the fundamental difference between flat surfaces and spherical surfaces, such as the Earth, is that any planar depiction of the Earth – such as a map on the wall, in an atlas, or on Google Maps – will necessarily have some distortions.

Watch a time-lapse video showing the Museum's smallest workers, flesh-eating beetles, preparing the skeletons of a great green macaw, tawny owl and mountain peacock-pheasant for our collections. Chemical preparation of skeletons can cause damage to the bones so a special beetle species, Dermestes haemarrhoidalis, is used to strip off the flesh while leaving the bones and collagen untouched.

Where are our mass-produced robot butlers already, the Rosies of our Jetsons families? Still a ways off, unfortunately, but here's the next best thing: 'Roboy,' a child-like service bot that researchers are billing as “one of the most advanced humanoid robots." Roboy, which the inventors are trying to create in nine months, is tendon-based, and it's modeled on people. Young ones, in this case. The idea is for it to help out with duties usually reserved for humans, depending on what the user needs. The robot, or at least similar robots, could help care for the elderly a la Robot & Frank, the researchers say. Roboy will also get so-called "soft skin," a layer of something to make it "safer and more pleasant." All of that sounds very human-like and, presumably, the team is trying to avoid the uncanny valley, that point where robots are just human enough to give us the creeps without passing for actual humans. The glimpses of Roboy we see right now are pretty charmingly cartoonish, so we'll have to wait and see just how the real-boy-versus-'bot balance plays out in the final version. The team, from the University of Zurich, is already five months into the nine-month project and planning on unveiling Roboy in March. In the meantime, you can check out the researchers' pagefor more info, and watch the promotional video above. It even has a sort of mad-scientist-ish Goethe quote! Via FutureCast
