Science
While swapping bodies remains fictional as of 2012, scientific research points to the possibility of head transplants, a brain transplant or mind uploading somewhere in the future.
In 1973 a group of scientists from Case Western Reserve University School of Medicine in Cleveland Ohio, led by Dr. Robert White, a neurosurgeon inspired by the work of Vladimir Demikhov, transplanted the head of one monkey onto another monkey's body. The animal was still able to smell, taste, hear, and see. The animal survived for eight days after the operation, even at times attempting to bite some of the staff. Dr. White successfully repeated the operation on a monkey in 2001.
In 2002, other head transplants were also conducted in Japan involving rats. Unlike the head transplants performed by Dr. White, however, these head transplants involved grafting one rat's head onto the body of another rat that kept its head. Thus the rat ended up with two heads.

Famous quotes containing the word science:
“But don’t despise error. When touched by genius, when led by chance, the most superior truth can come into being from even the most foolish error. The important inventions which have been brought about in every realm of science from false hypotheses number in the hundreds, indeed in the thousands.”
—Stefan Zweig (18811942)
“There are two kinds of truth; the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art.... Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery.”
—Raymond Chandler (1888–1959)
“Religions die when they are proved to be true. Science is the record of dead religions.”
—Oscar Wilde (1854–1900)
