Astronomically Improving Stem Cell Creation

The efficiency of making "induced pluripotent stem cells" cells has leapt overnight from less than 10% to over 90%, according to The Nobel Prize-winning iPSC approach-which lets researchers create potent embryonic-like stem cells from ordinary adult cells-has suffered glitches, key among them inefficiency.
