An article at ScienceDaily (found via Transhumanity) discusses a new potential cancer cure currently in the labs: number 18 since we started keeping count in late 2002. The cancer therapy field is poised for a real explosion in effectiveness and range of therapies. This one is especially novel: stem cells seek out cancer cells and produce biological killing agents on site. It is even capable of attacking metastasized cancer - an amazing breakthrough in the field if verified. Defeating cancer is vital to healthy life extension, and enormous strides are being made.
