Nobody expected a great surprise. Genetic testing of the little finger of an early hominin child found in the Siberian Denisova Cave, Kostenki, in the middle of archeological remains pertaining to Upper Paleolithic culture, would almost for sure confirm DNA similar to ours. There was a slim change that the pinky belonged to a Neanderthal from the neighborhood that got lost, but everything pointed at a an unequivocal member of the advanced group of hominins responsible for introducing symbolic art all over the world, the so-called anatomically modern humans (AMH). The collection of personal adornments and artifacts suggestive of symbolic behavior from the Early Upper Paleolithic deposits of Denisova Cave, Altai, is one of the earliest and the most representative of the Upper Paleolithic assemblages from Northern and Central Asia.

Nanotechnology Basics
What is Nanotechnology? Answers differ depending on who you ask, and their background. Broadly speaking however, nanotechnology is the act of purposefully manipulating matter at the atomic scale, otherwise known as the "nanoscale."
Artificial Robotic Hand Transmits Feeling To Nerves | BotJunkie
Writing by Evan Ackerman on Tuesday, 20 of October , 2009 at 12:50 am DEKA’s prosthetic robot arm is commonly referred to as the “Luke” arm, but this new robotic hand may be more appropriate for that title, at least as far as the movie goes. Not only is this artificial hand, called the SmartHand, controlled directly by the brain (as opposed to actuated by muscle movements), but it provides some degree of feedback to the nerves of the user, including pressure and even texture (!). So this guy can actually feel things through the robot hand. It’s a neural interface.
Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here. But to understand what all of that means, you'll really want to read on.

List of common misconceptions - Wikipedia, the free encyclopedia
This incomplete list is not intended to be exhaustive. This is a list of current, widely held, erroneous ideas and beliefs about notable topics which have been reported by reliable sources from around the world. Each has been discussed in published literature, as has its topic area and the facts concerning it. In ancient Rome , the architectural feature called a vomitorium was the entranceway through which crowds entered and exited a stadium, not a special room used for purging food during meals. [ 1 ] Although wealthy gluttons and emperors with excessive appetites might be accused of binging and purging, vomiting was not a regular part of Roman dining customs . [ 2 ]
and, It also made me feel a little young becuase i didn't care about some of these also, about the ages, that is just really retarded, Who cares what age cartoon were???

The planets that survived being inside a star (Apr 3, 2012) Two small planets found orbiting KIC 05807616 may be fragments of a much larger world that was swallowed up when the star became a red giant . A massive super-Jupiter, a new theory suggests, broke apart in the intense heat leaving behind the fragments we now see circling around the star after its surface receded. Is nature natural? (Apr 2, 2012) In the Standard Model of particle physics, the mass of the Higgs boson has to be fantastically fine-tuned.

Although it would be impossible to do this on earth, you actually could do this on the moon . The moon has a cold core and it also doesn't have any oceans or groundwater to mess things up. In addition, the moon has no atmosphere, so the tunnel would have a nice vacuum in it that eliminates aerodynamic drag . So, imagine that the tunnel through the moon is 20 feet (7 meters) in diameter. Down one side is a ladder.
That’s what I said – you can print skin . Not print on skin, print the skin itself, cell layer by layer. Bioprinting custom skin grafts means you can customize a graft’s depth to treat severe burns – using the patient’s own cells to avoid rejection. Update: Jason at the Thoughtful Animal just sent me a 2008 minireview on this process by Henmi et al, “New approaches for tissue engineering: three dimensional cell patterning using inkjet technology.” It appears to have been sponsored in part by Epson.
If you reload an inkjet cartridge with human cells, can you print skin? YES! : bioephemera
Why are past, present, and future our only options?
In this week's "Ask a Physicist," we're going to figure out why the universe we inhabit isn't Flatland, Tesseractland, or Doubletimeland. Or, at very least, we're going to figure out why those worlds would suck at harboring complex life. It is a stoner question, but that won't stop me from answering it.Robert Lanza, M.D.: Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone
Recent discoveries require us to rethink our understanding of history. "The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history." Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future -- and may even depend on actions that you haven't taken yet. In 2002, scientists carried out an amazing experiment, which showed that particles of light "photons" knew -- in advance −- what their distant twins would do in the future.Public release date: 13-Oct-2004 [ Print | E-mail | Share ] [ Close Window ] New Scientist Boston office The cosmos was born in a churning fluid 300 million times hotter than the sun. We've recreated this hell, and it's not just hot, it is also very, very strange, says Amanda Gefter ( science writer based in London).
