Limbaugh's a KNOWN drug addict, so he should expect to be given extra scrutiny going through airports.

'Virgin birth' stem cells bypass ethical objections

Early human embryos grown from unfertilised eggs are not viable - but this means that their stem cells could be used to treat disease without upsetting religious sensibilities.


"VIRGIN-BIRTH" embryos have given rise to human embryonic stem cells capable of differentiating into neurons. The embryos were produced by parthenogenesis, a form of asexual reproduction in which eggs can develop into embryos without being fertilised by sperm. The technique could lead to a source of embryonic stem (ES) cells that could be used therapeutically without having to destroy a viable embryo.

Human eggs have two sets of chromosomes until fertilisation, when the second set is usually expelled. If this expulsion is blocked but the egg is accidentally or experimentally activated as if it had been fertilised, a parthenote is formed (see Diagram).

Because some of the genes needed for development are only activated in chromosomes from the sperm, human parthenotes never develop past a few days
. This means that stem cells taken from them should bypass ethical objections of harvesting them from embryos with the potential to form....
