"Nanoparticles disguised as red blood cells could be used to deliver anti-cancer drugs directly to a tumour. So say researchers at the University of California at San Diego, whose new technique is unique in its approach to harnessing nanoparticles..." Via Gerd Moe-Behrens

A French doctor has completed the first-ever artificial blood transfusion after extracting stem cells from a patient's bone marrow, which were then used to grow the red blood cells under laboratory settings. "After five days, 94 to 100 percent of the blood cells remained circulating in the body. After 26 days, 41 to 63 percent remained, which is a normal survival rate for naturally produced blood cells." The cells carried oxygen throughout the patient's body, just as normal red blood cells would.
