Apr 17, 2014 — Scientists based their technique on the one used to create the sheep Dolly years ago. These cells might one day be useful in treating all sorts of diseases.
Apr 1, 2014 — The lead author of a recent "breakthrough study" fabricated the data and is guilty of scientific misconduct, according to a Japanese research panel. The scientist says she will appeal the judgment.
Jan 29, 2014 — Japanese scientists say they've figured out a fast, easy way to make the most powerful cells in the world: embryonic stem cells. The magic ingredient? Something akin to lemon juice. So far it's unknown whether the method would work with human cells or could be used for medical treatments.
Oct 21, 2013 — The new method might allow doctors to increase the quantity of hair on your head, instead of just moving it around. But don't get too excited. A cure for baldness is not around the corner. The method has been tested only in mice and can produce only a small amount of strange-looking hair.
Jul 3, 2013 — The tiny organs created from stem cells aren't complete, but they act like regular livers when transplanted into mice, Japanese scientists say. Still, it will be years before the synthetic organs could help people with liver problems, even if further research all works out as hoped.
Jun 12, 2013 — Since the 1970s, doctors around the world have reported cases in which young kids regrow fingertips if an accident leaves some of the fingernail. Now scientists have figured out how this lizard-like regeneration happens in mice and suspect the same mechanism works in young humans.
May 23, 2013 — Biologists said last week that they had overcome a major obstacle in stem-cell research by cloning human embryos. But several images in the published study were duplicated and labeled incorrectly, prompting questions about the authenticity of the results.
May 16, 2013 — The news that scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the creation of Dolly the sheep. It's a fight that has, over the past decade and a half, produced a lot of heat and light and not a lot of policy.
May 15, 2013 — After decades of trying, scientists say they've finally figured out how to make personalized embryonic stem cells. One day, these designer cells may help treat an array of diseases. A jolt of caffeine and and a little electric shock helped to do the trick.
May 15, 2013 — The achievement is a long-sought step toward harnessing the potential power of such cells to treat diseases. But the discovery raises ethical concerns because it brings researchers closer to cloning humans.
