Planetary Society’s Cosmos 1 Solar Sail Ready for Flight - Space.com  A clicking countdown clock has started, leading to a liftoff of the orbital mission of Cosmos 1 -- billed as the world’s first solar sail spacecraft. "It’s been a long road…four years of development," said Louis Friedman, Executive Director of The Planetary Society and Project Director of Cosmos 1 at a briefing today from the group’s facilities. "This is very much a citizen’s supported project," he adds. Once the solar sail spacecraft is in Earth orbit, a set of 8 triangular sail blades are to be deployed by inflatable tubes, Friedman said. Several days to perhaps a week of checkout is likely before the blades are in position, he added. "Then we will begin to fly what we hope is controlled solar sail flight within the second week of the mission…and declare victory," Friedman noted.   
Cassini Spots Possible Ice Volcano On Titan - SpaceDaily  A strikingly bright feature that is consistent with an active geology has been seen in one of Cassini's first radar images of Saturn's moon Titan. There are many possibilities for what it is but one of the leading candidates is that it may be a 'cryovolcanic' flow or 'ice volcano'. "It may be something that flowed," said Cassini radar team member Dr. Ralph Lorenz of the University of Arizona, Tucson. "Or it could be something carved by erosion. It's too early to say. But it looks very much like it's something that oozed across the surface. It may be some sort of cryovolcanic flow.

Returning rhythm How stem cells could lead to a biological pacemaker  - BBC  Left:  Engineered stem cells could return the rhythm.  Ira Cohen, of the State University of New York at Stony Brook, US, says the pacemaker manufacturer Guidant is funding the project to see whether immature cells from the bone marrow can be genetically engineered to create pulsations that drive the human heart. A heartbeat is initiated by an electrical pulse generated by the pacemaker cells. As the current hits neighbouring cells, they too release charge, and a wave of electrical activity perfuses the heart tissue, triggering muscle contraction as it passes by.
