Technology Research News March 12, 2003 Kimberly Patch	Cheap solar power on deck Researchers from the University of California at Santa Barbara have come up with a new type of solar cell that may be much less expensive to manufacture than today's solar cells and can be improved to be nearly as efficient.
Technology Research News March 12, 2003 Kimberly Patch	Paper speeds video access A new device that uses paper transcripts as an interface to digital video could eventually make it quicker and easier to access video records, including those of historical figures, court trials and medical procedures.
Technology Research News March 12, 2003 Eric Smalley	Chip device gets to the point A major leap forward in science is the ability of researchers to manipulate matter atom by atom. The primary tool of this new trade is the atomic force microscope, an probe moved by a high-resolution positioner. Now researchers have made an inexpensive positioner-on-a-chip.
Technology Research News March 12, 2003	Warping yields better light chip Light can transmit information and it can sense chemicals and microbes. The critical device for controlling light for these uses is the resonator, which briefly stores light of a specific frequency, or color. A newly developed resonator is nearly 10,000 times more efficient than previous designs.
Technology Research News March 12, 2003	Supersensitive disk drives on tap Being able to move electrons from one place to another more efficiently translates to more sensitive electronics that can read information packed more closely on disk drives. New research paves the way for storage devices that hold several thousand gigabits per square inch. Today's hold 50.
Technology Research News March 12, 2003	Lasers tweeze every which way Researchers from the University of Glasgow in Scotland have found a way to use a pair of laser beams to rotate an object in three dimensions, turning it like a ball rather than a wheel.
Technology Research News March 12, 2003	RNA forms nanomotor Researchers from Purdue University have constructed a tiny motor from DNA and RNA molecules. The device, fueled by ATP, which powers our own movements, could eventually power nanomachines.
Technology Research News March 12, 2003	Cold logic promises speedy devices Researchers from the University of Cambridge and Hitachi Cambridge Laboratory have made a superconducting logic circuit that computes very quickly and requires little power.
Technology Research News March 12, 2003	Net has few degrees of separation Researchers have found that the average number of connections needed to get from one point to another in real-world networks like the Internet and social networks is smaller than the number needed for randomly-connected networks. The findings could lead to improved networks.
Popular Mechanics March 2003 Paul Eisenstein	World's Most Powerful Magnet The "magnetar," or magnetic neutron star known as Soft Gamma Repeater 1806-20, is the most powerful known magnetic object in the universe. While it's unlikely anything man-made will ever come close to the power of a magnetar, it's not for lack of trying.
