Stem cell surprise for tissue regeneration

Audio-Plus Press Release
Scientists working at the Carnegie Institution’s Department of Embryology have overturned previous research that identified critical genes for making muscle stem cells. It turns out that the genes that make muscle stem cells in the embryo are surprisingly not needed in adult muscle stem cells to regenerate muscles after injury. The finding challenges the current course of research into muscular dystrophy, muscle injury, and regenerative medicine; it also favors using age-matched stem cells for therapy.

Merging Galaxies Create a Binary Quasar

Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies. Binary quasars, like other quasars, are thought to be the product of galaxy mergers. Until now, however, binary quasars have not been seen in galaxies that are unambiguously in the act of merging.  But images of a new binary quasar from the Carnegie Institution’s Magellan telescope in Chile show two distinct galaxies with “tails” produced by tidal forces from their mutual gravitational attraction.  Watch movie

Gene Function Discovery: Guilt by Association

Scientists, including Plant Biology's Sue Rhee, have created a new computational model that can be used to predict gene function of uncharacterized plant genes with unprecedented speed and accuracy. The network, dubbed AraNet, has over 19,600 genes associated to each other by over 1 million links and can increase the discovery rate of new genes affiliated with a given trait tenfold. It is a huge boost to fundamental plant biology and agricultural research.
