I realize that people are against cloning just to retrieve stem cells, but how can they argue so vehemently about the subject when most do not even fully comprehend it? Stem cells are cells which are unspecialized. That is to say they can develop into any of the 220 different types of cells in your body. Embryonic stem cells can only be found within the first 10 days after fertilization and removing them means immediate death for the embryo. The other type of stem cells, called adult stem cells, exist in everyone, but can only differentiate into certain types of cells. That's right, everyone has stem cells in them, which, by using newly developed techniques, could be cultured to produce living tissue which could be replaced into the body. Stem cells and, obviously, stem cell research can only result in cures for diseases such as Alzheimer's, Parkinson's and a ton of other of conditions. So why is everyone so against stem cell research when it can only do us good?

We can all agree that sound is created when the partivcles around the moving (or vibrating) object, vibrate, right? Now, why when you move or "clap with one hand' why is there no sound created? Aren't you moving paricles? I know this is probably a really simple question to answer.. but.. hey.. i don't know. lol
