Technology Research News September 24, 2003	Rapid Process Shapes Aluminum Rapid prototyping processes are routinely used for plastics and some metals, but aluminum has proved elusive. Researchers in Australia have come up with a rapid manufacturing process for aluminum that infiltrates an aluminum alloy powder with a liquid aluminum alloy.
Technology Research News September 24, 2003	3D display goes deeper Researchers from Seoul National University in Korea have found a way to deepen one type of three-dimensional display method -- integral imaging -- that has historically suffered from relatively shallow depth, but does not require users to wear glasses.
Technology Research News September 24, 2003	Artificial DNA stacks metal atoms In recent years, researchers have replaced some of DNA's natural bases with those that attach to metal atoms in order to coax DNA to organize metal ions into tiny structures. Researchers in Japan have tapped the method to form stacks of single metal ions.
Technology Research News September 24, 2003	Teamed lasers make smaller spots Researchers from Boston University have tapped the properties of polarization in order to focus a laser beam more tightly in space. The method could be used to scan objects in finer detail and to make finer features in processes like rapid prototyping and photolithography.
Technology Research News September 24, 2003	Glow shows individual DNA Researchers have made a type of artificial DNA of that glows when it combines with a specific sequence of natural DNA. In principle, the method could be used to develop DNA chips that directly sense individual DNA molecules.
BusinessWeek September 29, 2003	Sanjay Sarma: Mighty Smart Labels The MIT researcher says radio-frequency ID tags are almost here -- and their uses will be mind-blowing, perhaps lifesaving.
Technology Research News September 10, 2003 Kimberly Patch	Display brighter than film Computer screens can't hold a candle to film where dynamic range is concerned, but that could change. A display with 10 times the brightness range of film and 300 times that of the average LCD promises to dramatically liven up medical images, video games and eventually even television.
Technology Research News September 10, 2003 Kimberly Patch	Sponges grow sturdy optical fiber Primitive sea creatures from the murky depths are providing tips on how to improve one of the fundamental technologies of the information age -- optical fiber. Sea sponge spines act like fiber optics, but with some key advantages.
Technology Research News September 10, 2003 Eric Smalley	Electron teams make bigger qubits Making quantum computers from electronic chips rather than cumbersome laboratory equipment requires control over individual electrons. A scheme that has a string of electrons acting as one could ease the task by expanding the target to a whopping 250 millionths of a millimeter.
Technology Research News September 10, 2003 Eric Smalley	Vision chip shines Robot eyes that are comparable to biological eyes are a long way off, but chips that work like retinas are sprouting up in laboratories around the world. An artificial retina that gives what it receives -- light -- is ready to plug into superfast all-optical circuits.
