Technology Research News April 6, 2005 Eric Smalley	Scheme Reverses Light Pulses Researchers have developed a method for accurately time-reversing electromagnetic pulses, making it possible to receive a light pulse and return a replica of exactly the same size, shape and wavelength.
Technology Research News April 6, 2005	Tough Material Gets Functional A University of California at San Diego researcher has made several useful versions of a metallic material that is as stiff as steel but only half as dense.
Technology Research News April 6, 2005	Water Shifts Rubber's Shape Researchers have developed a material that can be shaped, but changes back to a permanent shape when immersed in water.
Technology Research News April 6, 2005	Interference Scheme Sharpens Focus Researchers have found a way to improve the resolution of lithographic systems that could extend the lifetime of the manufacturing technique. Their proof-of-principal experiments show that the technique improves resolution by three times.
Technology Research News April 6, 2005	System Forms Light Necklace Researchers who are working with soliton clusters have come a step closer to all-optical computing. They have showed that it is possible to contain a lightwave as a soliton necklace -- a standing wave of light arranged as a ring of bright spots.
Technology Research News April 6, 2005	Trapped Light Pulses Interact Researchers at Harvard University have showed that light pulses can be trapped and held in a rubidium vapor and made to interact with one another. The method could eventually be used in quantum cryptographic and quantum computing schemes.
Technology Research News April 6, 2005	Optics Demo Does Quantum Logic Researchers from the University of Science and Technology of China and the University of Heidelberg in Germany have demonstrated a method of using four photons to form a logic gate that can be used for quantum computing.
Technology Research News April 6, 2005	Strained Material Cleans up Memory Researchers have found a way to make a promising type of flash computer memory that does not contain environmentally toxic lead.
Popular Mechanics April 2005 Tom Clynes	Playing With Fire When they burn space shuttle fuel, hit speeds of mach 2 and climb to 15,000 ft., do you still call them model rockets? Welcome to the world of extreme hobbies.
IEEE Spectrum April 2005 Alan Sullivan	3-Deep New displays render images you can almost reach out and touch. A few small companies are just now emerging to try to carve out a piece of a market for volumetric displays that could be worth $1 billion by 2006.
