the fatty network of connective tissue that fills the cavities of bones
Opponents say the promise of embryo research has been oversold, and they point to the cures that have been derived from adult stem cells from bone marrow and umbilical cords; supporters retort that adult stem cells are still of limited use, and to fully realize their potential we would need to know more about how they operate--which we can learn only from studying leftover fertility-clinic embryos that would otherwise be thrown away.
Opponents of ESC research--starting with Bush--argue that you can't destroy life in order to save it; supporters argue that an eight-cell embryo doesn't count as a human life in the first place--not when compared with the life it could help save.
membranous duct connecting the fetus with the placenta

a person with advanced knowledge of empirical fields
Scientists who are having surprising success with adult stem cells find their progress being used by activists to argue that embryo research is not just immoral but also unnecessary.
a collection of facts from which conclusions may be drawn
Stem-cell research has joined global warming and evolution science as fields in which the very facts are put to a vote, a public spectacle in which data wrestle dogma.
sequence of events involved in the development of a species
