University of Manchester researchers have transformed fat tissue stem cells into nerve cells -- and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life. In a study published in October's Experimental Neurology, Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration (UKCTR) isolated the stem cells from the fat tissue of adult animals and differentiated them into nerve cells to be used for repair and regeneration of injured nerves. They are now about to start a trial extracting stem cells from fat tissue of volunteer adult patients, in order to compare in the laboratory human and animal stem cells.

Hugh Pickens writes "Researchers at Dartmouth University have recently discovered that infrequent anonymous contributors, so called "Good Samaritans," are as reliable as registered users who update constantly and have a reputation to maintain. A graph from page 31 of the group's original paper (pdf file) shows that the quality of contributions of anonymous users goes down as the number of edits increases while quality goes up with the number of edits for registered users."
