As recently as 1993, when Dr. Sherwin Nuland wrote the best seller "How We Die," the conventional answer was that it was his cells that had died. The patient couldn't be revived because the tissues of his brain and heart had suffered irreversible damage from lack of oxygen. This process was understood to begin after just four or five minutes. If the patient doesn't receive cardiopulmonary resuscitation within that time, and if his heart can't be restarted soon thereafter, he is unlikely to recover. That dogma went unquestioned until researchers actually looked at oxygen-starved heart cells under a microscope. What they saw amazed them, according to Dr. Lance Becker, an authority on emergency medicine at the University of Pennsylvania. "After one hour," he says, "we couldn't see evidence the cells had died. We thought we'd done something wrong." In fact, cells cut off from their blood supply died only hours later.
But if the cells are still alive, why can't doctors revive someone who has been dead for an hour? Because once the cells have been without oxygen for more than five minutes, they die when their oxygen supply is resumed. It was that "astounding" discovery, Becker says, that led him to his post as the director of Penn's Center for Resuscitation Science, a newly created research institute operating on one of medicine's newest frontiers: treating the dead.
Biologists are still grappling with the implications of this new view of cell death—not passive extinguishment, like a candle flickering out when you cover it with a glass, but an active biochemical event triggered by "reperfusion," the resumption of oxygen supply. The research takes them deep into the machinery of the cell, to the tiny membrane-enclosed structures known as mitochondria where cellular fuel is oxidized to provide energy. Mitochondria control the process known as apoptosis, the programmed death of abnormal cells that is the body's primary defense against cancer. "It looks to us," says Becker, "as if the cellular surveillance mechanism cannot tell the difference between a cancer cell and a cell being reperfused with oxygen. Something throws the switch that makes the cell die." -
ok, so we can make zombies and stuff? ^_^

It's about the Mitochodrion. If we could alter some of the propeties, maybe we could save more life..

A) i don't care about how human dies
B) i am more interested in cloning, think of this for a moment, imagine, that you can gain eternal life just by cloning yourself, forever
as for the memory, if i was a scientist, i will find a way, to retrieve my old memory, and implant into a temporary vessel, and when my 'new' body is ready, i will implant back my old memory again, plus i get to have a new body
its a way to redefine nature -
do u really think that by cloning a copy of u in front of you, that means u are now the new body. assuming the new body is in front of you, are you still you? or the new body? The new body may have same things as you but the new body is still himself. you are standing at position A and he is B. you will still grow old and die and he will do his own things and be himself still.Originally posted by allentyb:A) i don't care about how human dies

cloning an external new body outside yourself is not going to make be the new body. you still belong to the body u are in now.
the best shot at staying alive is ability to repair your cells, organs by replacement or cloning new organs and put in ur body and all this are still not mastered yet.
Human is still likely to die one way or another given our current medical technology and knowledge, which makes me feel abit sads sometimes to noe that i am going to die one day. -

does it really matter, whether the new body is me or not, to achieve semi immortality is beyond anybody imagination,Originally posted by january:do u really think that by cloning a copy of u in front of you, that means u are now the new body. assuming the new body is in front of you, are you still you? or the new body?

question is, will i be happy if i have obtain a new body?
in the current biotechnology, cloning have proven to be realistic enough that human can play as the hand of god.
i am referring to embryo cloning and Human genetic engineering.

are you seriously thinking, that i think too much or i didn't read enough in the news bulletin, before i make my statementOriginally posted by gigabyte14:don't think too much 
i am not a person who bull s h i t, without finding article to proof my statement
neither am i ignorant nor naive,
the question is, are you ready to mess around with the hand of god, if the technology is successfully enough to be commercialise
and do you think, there is no one in this world, does not want to achieve semi immortality? -
