New Scientist: Researchers led by Derrick Rossi of the Children’s Hospital Boston have created induced pluripotent stem cells (iPSCs) from adult skin cells; the resulting iPSCs have the same capacity as primordial embryonic stem cells to turn into almost every tissue of the body, but don’t involve the use of embryos. The group’s research was published in the journal Cell Stem Cell. Robert Lanza, chief scientific officer at Advanced Cell Technology in Worcester, Massachusetts, called it a game-changer. “If repeatable, it would solve some of the most important problems in the field,” he said. The announcement comes as the future of federal funding for embryonic stem-cell research hangs in doubt.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
