Adult Brains Can Heal Themselves
Past research has established the remarkable capacity of young brains to change or adapt to deficits by creating new signaling routes, a phenomenon called plasticity. However, whether adult brains have that same capacity has remained controversial.
Results from a new study, published in the Sept. 5 online edition of the Journal of Neuroscience, suggest at least in one patient, the visual center of an adult brain can reorganize itself neurally to overcome damaged pathways and result in changes (and possibly improvements) in visual perception.
The new finding adds weight to suggestions made by other research about the ability of adult brains to morph.
This year, neuroscientists reported the adult mice could grow new neurons, a finding they said could have implications for the treatment of human neurodegenerative diseases such as Parkinson's. A similar finding was reported a couple of years ago in mice. In 2005, a brain-scan study of human adults with macular degeneration showed evidence of plasticity in the visual regions of their brains.

Yogis
When I first saw pictures in books of yogis sitting cross-legged in the woods in the forests of India, something would make me look twice. I'd notice their faces. And it wasn't the face of a man wasting time. It was the face of a man holding something that I not only wanted, but I didn't know about. I was drawn to it. There was such a presence of power and dignity -- and an absence of fear. Many of their countenances held playfulness or love, or power and strength.-- David Lynch, Catching the Big Fish: Meditation, Consciousness, and Creativity (2006)

Every society has a certain center of gravity, around which the culture's ethics, norms, rules, and basic institutions are organized, and this center of gravity provides the basic cultural cohesion and social integration for that society. This cultural center of gravity acts like a magnet on individual development. If you are below the average level, it tends to pull you up. If you try to go above it, it tends to pull you down.-- Ken Wilber, A Brief History of Everything

Scientists induce out-of-body sensation with virtual reality
Using virtual reality goggles, a camera and a stick, scientists have induced out-of-body experiences in healthy people, according to experiments being published in the journal Science. When people gaze at an illusory image of themselves through the goggles and are prodded in just the right way with the stick, they feel as if they have left their bodies.
The research reveals that "the sense of having a body, of being in a bodily self," is actually constructed from multiple sensory streams...Full story:

Transported by Peyote I saw that I had to defend what I am before I was born, and that my Self is merely the consequence of the battle I waged in the Supreme against the untruth of evil ideas. -- Antonin Artaud, The Peyote Dance21 August 2007

Walking damages environment more than driving?
Walking does more than driving to cause global warming, a leading environmentalist has calculated. Food production is now so energy-intensive that more carbon is emitted providing a person with enough calories to walk to the shops than a car would emit over the same distance.
"A chilled ready meal is a perfect example of where the energy is wasted. You make the meal, then use an enormous amount of energy to chill it and keep it chilled through warehousing and storage.” The ideal diet would consist of cereals and pulses. “This is a route which virtually nobody, apart from a vegan, is going to follow,” Mr Goodall said. But there are other ways to reduce the carbon footprint. “Don’t buy anything from the supermarket,” Mr Goodall said, “or anything that’s travelled too far.”
