Researchers report a game-changing advance in stem cell science: the creation of long-term, self-renewing, primitive neural precursor cells from human embryonic stem cells (hESCs) that can be directed to become many types of neuron without increased risk of tumor formation.

IMHO,this is the single most important breakthrough in science since the sequencing of the human genome. The ability to create millions of stable, implantable, neurological "building blocks" opens the doors for all the "magic" science you've been dreaming of - from repairing nerve sheaths in Multiple Sclerosis sufferers, to repairing the brains of Alzheimer's patients. In fact, what we are now seeing is a shift from chemical based treatments to biologically active treatments, and this single breakthrough now makes HUGE amounts of research possible. Regenerative medicine just entered the 21st century. Things are about to get very interesting...
