A new computed tomography (CT) scanner from Imatron Inc. could eliminate 20 to 40 % of the 2 million angiograms performed annually in the U.S. It uses electron beam technology (EBT) that is based on a scanning electron beam that scans at speeds of once every 50 to 100 milliseconds. Unlike angiograms, EBT is non-invasive. It allows doctors to see coronary arteries without the unpleasant procedure of inserting a tube into the patient's artery. "The EBT scanner provides a very focused image," says Ray Rand, an Imatron physicist. Other possible applications for EBT include scanning luggage for bomb detection at airports.

Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
