Stem cells not unique in ability to regenerate?
NYU (US)—A quality thought only to exist in stem cells, may occur in ordinary cells, too. Findings by researchers at New York University’s Center for Genomics and Systems Biology and Utrecht University in the Netherlands indicate that some roles of stem cells in organ regeneration may be shared by other types of cells.

Two-armed nanorobot captures DNA molecules
NYU (US)—Scientists from the United States and China have designed one of the world’s smallest robots. The programmable two-armed device could be used to create new DNA structures, serving as a factory of sorts for assembling the building blocks of new materials. Applications range from developing new synthetic fibers to improving data encryption.

Cassini maps weather on Saturn’s massive moon
JOHNS HOPKINS (US)—The rippled sand dunes on Titan tell a story of wind and weather. After four years of data collection by NASA’s Cassini spacecraft, scientists have mapped the dune fields on Saturn’s largest moon. The results could prove significant for planning future Titan explorations that might involve balloon-borne experiments.

Gamers want the challenge not the gore
U. ROCHESTER (US)—Video gamers, it turns out, don’t crave carnage and may actually be turned off by graphic violence. The thrill of mastering a skill or rising to a challenge are the elements that keep players coming back for more. Those findings come from a series of online surveys and experiments conducted by investigators at the University of Rochester and Immersyve Inc. (www.immersyve.com), a player-experience research firm.
