Blood Helps Us Think
As it is pumped through blood vessels and delivers oxygen to brain cells, blood may actually help us think.
Research done by scientists at MIT suggests that in addition to providing nutrients and oxygen to the body's cells, blood may affect the activity of neurons in the brain as it flows through, changing how they transmit signals to each other and regulating the flow of information through the brain.
"We hypothesize that blood actively modulates how neurons process information," said researcher Christopher Moore in an invited review in the Journal of Neurophysiology. "Many lines of evidence suggest that blood does something more interesting than just delivering supplies. If it does modulate how neurons relay signals, that changes how we think the brain works."
This relationship between blood flow and brain function has implications for understanding neurological diseases, such as Alzheimer's disease, schizophrenia, multiple sclerosis and epilepsy.

Blood Helps Us Think
Although he is more revered for his role as an author, Clarke has well deserved the title of futurist for his groundbreaking thinking on space exploration.
In October 1945, he published a paper in the magazine Wireless World called “Extra-Terrestrial Relays: Can Rocket Stations Give Worldwide Radio Coverage?” In it, he predicted that geostationary satellites would soon become the basis of global communications. And in his 1979 novel, The Fountains of Paradise, he describes a space elevator that would ferry passengers and cargo to a docked space station, a concept that is currently undergoing its first primitive implementations.
Sympathy of 'Souls'
Telepathy, more often known, today, as ESP - is thought of as the most common of all paranormal phenomena. Yet, at the same time, it is also one of the most problematic, in being contrary to what science tells us about mind and the universe.
To science the mind is disconnected from other minds and the universe. Hence, any ability for mind to mind contact is impossible. The nearest such instant communication will come is, they advise, text messaging.
