Leukemia is a malignant disease of the bone marrow and blood. It is characterized by the uncontrolled growth of blood cells. The term leukemia has a Latin derivation. Leuko means white and heme is blood. Therefore the word leukemia literally means white blood. The common types of leukemia are div...

Stem cell research has been a very controversial subject for a very long time. Just this past November 2nd 2004 California voters approved a $3 billion Proposition to fund human embryonic stem-cell experiments. Proposition 71 became the largest state-wide research program to be approved in the coun...
