Video of Limbaugh mocking Fox & Fox's ad for a Republican
Nice try, Gov. wallace - but that particular right-wing talking point is easily dismissed via Wikipedia:
http://en.wikipedia.org/wiki/Stem_cell#Embryonic_Stem_Cells
Embryonic stem cells (ESCs) are stem cells derived from the inner cell mass of a blastocyst, which is an early stage embryo - approximately 4 to 5 days old in humans - consisting of 50-150 cells. Embryonic stem cells are pluripotent, meaning they are able to differentiate into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. In other words, they can develop into each of the more than 200 cell types of the adult body when given sufficient and necessary stimulation for a specific cell type. When given no stimuli for differentiation, ESCs will continue to divide in vitro and each daughter cell will remain pluripotent. The pluripotency of ESCs distinguishes them from adult stem cells or progenitor cells, the latter two only having the capacity to form a more limited number of different cell types.
Because of their unique combined abilities of unlimited expansion and pluripotency, embryonic stem cells are a potential source for regenerative medicine and tissue replacement after injury or disease. To date, no approved medical treatments have been derived from embryonic stem cell research. This is not unusual for a new medical research field; in this case, the first human embryonic stem cell line was only reported in 1998.

Daphne, that's not fair... how well can someone dance to Tom Jones "It's Not Unusual"? hehe
He always cracked me up when he danced to that.

8 of the 12 videos on that page are homegrown stuff and could not be classified in any sense viral, unless Jake is a plant for the Ukekele industry.
yes we do moderate and delete content that we don't feel is up to par. This is not unusual in a community site.
