“In the 1970′s the Princeton physicist Gerard O’Neill with the help of NASA Ames Research Center and Stanford University held a series of space colony summer studies which explored the possibilities of humans living in giant orbiting spaceships. Colonies housing about 10,000 people were designed and a number of artistic renderings of the concepts were made.”

Human cortical neural stem cells
Cortical neurons are located in the cerebral cortex of the brain, a region responsible for memory, thought, language, and consciousness. Neural stem cells are “immature” cells committed to become neurons and helper cells of the brain. Neurons are the liaison between our brain and the world. When we eat a lemon, neurons connected to our taste buds tell the brain that it’s sour. Messages from the brain can also be sent elsewhere, as when neurons command muscles to contract while lifting a heavy object.
