Technology Research News April 20, 2005 Kimberly Patch	Summarizer Ranks Sentences Researchers have developed a multi-document summarization technique that compares sentences and has the effect of sentences voting for the most important among them.
Technology Research News April 20, 2005	Ultraviolet Shifts Plastic's Shape Researchers have concocted a polymer material that can be switched from one shape to another in the presence of the right wavelengths of ultraviolet light.
Technology Research News April 20, 2005	Spiral Laser Beam Demoed Researchers have found a way to generate helico-conical, or spiral-shaped light beams. The unusual-shaped beams are potentially useful in trapping and manipulating particles in biological and medical devices, including biochips.
Technology Research News April 20, 2005	Nanotube Chemical Sensor Gains Speed Researchers have made single-walled carbon nanotube chemical sensors that transmit information by measuring the charge in the nanotubes' capacitance, or ability to store electric charge.
Technology Research News April 20, 2005	Trapped Cells Make Micromotors Researchers have showed that it is possible to make live Chlamydomonas reinhardtii cells rotate while pinned in a laser trap. The energy of a light beam can be used to manipulate and trap cells much like the way wind moves objects a larger scale.
BusinessWeek April 25, 2005 Cliff Edwards	Intel's WiMax: Like Wi-Fi On Steroids The chipmaker's ultrafast "Wi-Fi on steroids" could transform the broadband landscape.
Scientific American April 18, 2005 Charles Q. Choi	Qubit Twist Bending nanotubes as mechanical quantum bits.
National Defense May 2005 Joe Pappalardo	Casualties of War Leading research at the Department of Veterans Affairs is aimed at helping soldiers who lost limbs in combat. At the core of this program are new technologies meant to seamlessly fuse prosthetics with the human body.
National Defense May 2005 Sandra I. Erwin	Military Researchers Launch War Against Hidden Explosives At least 75 Navy scientists have been assigned to work full-time on technologies to detect and neutralize the improvised explosives devices that have killed and maimed hundreds of U.S. troops in Iraq.
National Defense May 2005 Joe Pappalardo	Soldiers Teaching Robots Battlefield Duties An Army Research Lab is working to instill robots with complex behaviors, thus making them suitable for the battlefield.
