Researchers report that these new stem-like cells do not express the same genes as embryonic stem cells and induced pluripotent stem cells (iPSCs) do. That explains why they don't produce tumors when they grow in the laboratory, as the other stem cells do, and why they are stable, producing the kind of cells researchers want them to.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151314.htmhttp://www.sciencedaily.com/releases/2012/11/121119151311.htm Chimpanzees and orangutans can experience a mid-life crisis just like humans, a study suggests.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151311.htmhttp://www.sciencedaily.com/releases/2012/11/121119151308.htm Pluripotent stem cells are nature's double-edged sword.

Natural disasters, climate change and the inability to adapt have all been proposed as theories to explain their disappearance. But now a Danish-Canadian research team has demonstrated the Norse society did not die out due to an inability to adapt to the Greenlandic diet: an isotopic analysis of their bones shows they ate plenty of seals.Mon, 19 Nov 2012 13:23:23 ESThttp://www.sciencedaily.com/releases/2012/11/121119132311.htmhttp://www.sciencedaily.com/releases/2012/11/121119132309.htm Hydrogen can easily dissolve and migrate within metals to make these otherwise ductile materials brittle and more prone to failures.

Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor?s topography on the various ?layers? of ocean water. At the American Physical Society?s (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe how the variation of density in ocean water can be used to cloak floating objects against incident surface waves.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104529.htmhttp://www.sciencedaily.com/releases/2012/11/121119104527.htm Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them.
