New Mini Generator To Run Electronics - SpaceDaily  Left: The microgenerator produces useful amounts of electricity by spinning a small magnet above a mesh of coils fabricated on a chip. Credits: Georgia Tech. The microgenerator is about 10 millimeters wide, or about the size of a dime. When coupled with a similarly sized gas-fueled microturbine (or jet) engine, the system, called a microengine, has the potential to deliver more energy and last 10 times longer than a conventional battery. The device’s magnet spins at 100,000 revolutions per minute (rpm). Speed like that is capable of producing 1.1 watts of power, or enough juice to run a cell phone, with a 20-to-50-watt goal.   
Outside View: US Amnesia On Pakistan - SpaceDaily  Left: The PHALANX system (part of the $1.3 billion arms package for Pakistan) is meant to defend ships against fast incoming missiles and aircrafts, which terrorists are unlikely to have. Pakistan, rather, is likely to employ them on ships conducting operations against India. Even as Pakistan's leadership was expressing its unrestrained glee with President George W. Bush's thumping re-election, the new Bush administration wasted no time in making its first big move to reward Pakistan with advanced weaponry. The deal includes eight P-3C Orion naval reconnaissance planes possibly with anti-ship and anti-submarine missiles, 2,000 TOW-2A heavy anti-armor guided missiles and the deadly PHALANX Close-In Weapon Systems for ships.     

Purdue Researchers Align Nanotubes To Improve Artificial Joints - SpaceDaily  Left:  This image, taken with a scanning electron microscope, shows arrays of nanofibers that have been aligned by pouring them into grids of tiny channels. Because the channels are so narrow, the tubes can only fit lengthwise, causing them to become aligned, similar to the way in which collagen fibers and natural ceramic crystals are aligned in bones. Because the nanofibers are aligned like natural collagen, they might be used to create better artificial joints that last longer and attach better to human bones.
