Scientists Repurpose Adult Cells - "Scientists have transformed one type of fully developed adult cell directly into another inside a living animal, a startling advance that could lead to cures for a variety of illnesses and sidestep the political and ethical quagmires associated with embryonic stem cell research."

More cuckoo than cuckoos: mate two salmon, get a... trout! Just give the parents a sperm transplant. And the sperm stem cells work in females too:

...Injecting the male cells into female salmon sometimes worked, too, prompting five female salmon to ovulate trout eggs.... The stem cells were still primitive enough to switch gears from sperm-producers to egg-producers when they wound up inside female organs....

Canadian scientists heal spinal injuries with stem cells from skin (in rats). "Over the course of their research, the team found that skin-derived stem cells share characteristics with embryonic neural stem cells, which generate the nervous system. ... After 12 weeks, the rats were able to walk better, with more co-ordination." [more inside]

Sea Squirt Regrows Entire Body from One Blood Vessel. Most famous as the creature that settles down and eats its own brain (though that is not exactly correct), it appears the humble sea squirt has spectacular regenerative abilities as well, thanks to regeneration niches packed with stem cells. All glory to the sea squirt!

Thou shalt not make scientific progress. "Medical research is poised to make a quantum leap that will benefit sufferers from Alzheimer's, Parkinson's, muscular dystrophy, diabetes and other diseases. But George W. Bush's religious convictions stand in its way."
