plasmacutter writes "The Video Lan dev team has recently come forward with a notice that the number of active developers for the project's MacOS X releases has dropped to zero, prompting a halt in the release schedule. There is now a disturbing possibility that support for Mac will be dropped as of 1.1.0. As the most versatile and user-friendly solution for bridging the video compatibility gap between OS X and windows, this will be a terrible loss for the Mac community. There is still hope, however, if the right volunteers come forward."

Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

Sockatume writes "Shingo Maeda and colleagues at Waseda University have created a polymer gel that walks under its own chemical power. The team exploited the oscillating Belousov-Zhabotinsky reaction to create periodic changes in the size of the polymer, and built a tensed structure that would amplify those small movements into a horrifically potent gait. The current version only walks across a notched surface, but the team are working on a terrible new form that will cross smooth surfaces like a snail. The team say they intend to apply it in the self-assembly of small structures. Suddenly, I can't stop screaming."
