All you anatomy and physiology brainiacs out there! (no pun intended.) Anyone know how to easily find the central sulcus on the human brain and possibly the sheep's brain? I know where it is on the diagrams but its a b*itch trying to find it on the real thing. HELP?!

The basic idea is to use the body as the basis for hardware, and the skin-covered surface of your body as an interface. As technologists have discovered, interfaces take up space; why not use your most intimate space to connect.

Here are some details:

To achieve absolute personal identification, the hardware would capture DNA from the user’s body, enabling direct participation in the political and cultural landscape. The technology would link remote users through engagement with their areas of interest...
Users view, test-drive, and select their product from a variety of options, both functional and aesthetic. They also set the lifecycle of the product, to be utilized for a few hours or a much longer amount of time. Once users are satisfied with their specific configurations, they have this fully-functioning circuitry - including all UI-interactive and display functions - “printed” onto recommended areas of their skin. Energy would be pulled from the human body to run the programs. At the end of the day, users would simply wash the Dattoos off, beginning anew the following day.
Although this is a very far-fetched idea, the first steps have already been taken. IBM pioneered research in the area of using a living person's skin as a computer network in 1996 with a system that could successfully transmit data across skin at low speeds. Microsoft was granted a patent in 2004 for "a method and apparatus for transmitting power and data using the human body."

More recently, NTT has developed a technology called RedTacton, which can send data over the surface of human skin at speeds of up to 2Mbps -- the equivalent of a fast broadband data connection. The transmission is achieved by minutely modulating the electrical body field in the same way that a radio station wave is modulated to carry broadcast data.

1) How much to the life, if he translates through the space fidget of atoms attracted by the biogenética formation of the species; that it is unicellular or multicellular until reaching the biogenética human being. 2) E how much to death - that it seems to be a body that if it loses, is, in the truth, a body that to the disconnect of the vital energy, vanishes to excuse the chemistry of atoms in the feeding of the nature.

be making the men turn gay? This question is with humour because I am not homophobic, but more seriously, I understand the effects of increased estrogen could be harmful to the eco system. Example male fish have been found with female organs. Could this be happening to humans in the gay sense???

A recent scientific paper which appeared in Nature in December 2006 has caused a furore in intellectual circles. Professor Heinz Stahl's work on Racial Divergence in Genetic Heritage shows us that Whereas Northern Europeans share 97% of their genes with the common Grasshopper, the average white (caucasian) American's DNA is exactly the same as the garden wasp. Are people in the U.S. threatened by this fact or do they see it as a liberating truth?
