In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, located beneath the Antarctic ice -- will finally be completed after two decades of planning. A new article provides a comprehensive description of the observatory, its instrumentation, and its scientific mission
Silicon oxide circuits break barrier: Nanocrystal conductors could lead to massive, robust 3-D storage

With a loud roar and mighty column of flame, NASA and ATK Aerospace Systems successfully completed a two-minute, full-scale test of the largest and most powerful solid rocket motor designed for flight. The motor is potentially transferable to future heavy-lift launch vehicle designs.
High-speed filter uses electrified nanostructures to purify water at low cost

Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.

I cannot forecast to you the action of Russia. It is a riddle wrapped in a mystery inside an enigma: but perhaps there is a key. That key is Russian national interest.
Success usually comes to those who are too busy to be looking for it.
Go and wake up your luck.
