The grooved band is one of three improvements that could significantly lower the cost of making solar power. Credit: Technology Review

Two Hubble Space Telescope storm watch images from late June and early September offer dramatically contrasting views of the martian surface. At left, the onset of smaller "seed" storms can be seen near the Hellas basin (lower right edge of Mars) and the northern polar cap. A similar surface view at right, taken over two months later, shows the fully developed extent of the obscuring global dust storm. Credit: J. Bell (Cornell), M.

Nanotube Self-Healing Power: Capsules holding carbon nanotubes can put the zazz back in broken circuits J. Mat. Chem./RSC Publishing 
In a carbon nanotube-based photodiode, electrons (blue) and holes (red) - the positively charged areas where electrons used to be before becoming excited - release their excess energy to efficiently create more electron-hole pairs when light is shined on the device. (Credit: Nathan Gabor)
One of the phototrophs used in the experiment was Chlorella vulgaris.
A baby killer whale surfaces near adults in Puget Sound. The calf was born in March 2009 to a pod that lives near the San Juan Islands off the coast of Washington State.
The Mars Society has examined copies of the cost projections being used by the Augustine Committee in currently considering the future of NASA's human spaceflight program. These estimates, generated by the Aerospace Corporation, a US Air Force funded policy oracle, have no scientific basis and have clearly been composed to make the case that human space exploration is unaffordable.
A copy of the Aerospace Corporation's bizarre cost estimates being used by the Augustine Committee is available here.
