Old Articles: <Older 521-530 Newer>

BusinessWeek December 15, 2003 Catherine Yang	Beyond Wi-Fi: A New Wireless Age Three technologies will boost the capacity of our airwaves -- and innovation, too
Geotimes December 2003 Wellmer & Kosinowski	Sustainable Development and the Use of Nonrenewable Resources Given enough time and with enough ingenuity, people can find long-term solutions for responsibly developing Earth's resources.
Geotimes December 2003 Hatheway et al.	Applied Geology in Service of the Public Welfare Engineering geologists play a crucial role in providing geological information to the public.
Technology Research News December 3, 2003 Eric Smalley	Biochip puts it all together Researchers have made all manner of microfluidic machines, but have yet to come up with cheap, mass-producible biochips for handheld medical and environmental testing. A simple plastic chip puts the necessary pieces together. The $7 device tests blood samples for the presence of E. coli bacteria.
Technology Research News December 3, 2003 Kimberly Patch	DNA assembles nanotube transistor Scientists have caused a transistor to self-assemble from a test tube concoction of DNA, proteins, antibodies, carbon nanotubes and minuscule specks of silver and gold. The feat shows that it is possible to assemble the smallest of machines and electronic devices by harnessing DNA's properties.
Technology Research News December 3, 2003 Eric Smalley	Chaotic lasers lock messages Researchers from Advanced Telecommunications Research Institute International in Japan have found a way for two people in different locations to work out a cryptographic key using the signal from the rapidly and randomly fluctuating light signal of a chaotic laser.
Technology Research News December 3, 2003	Nanotubes detect nerve gas Naval Research Laboratory researchers have found that carbon nanotubes are sensitive to extremely small concentrations -- less than one part per billion -- of chemical nerve agents.
Technology Research News December 3, 2003	Layers promise cheap storage Princeton University and Hewlett-Packard Laboratories researchers have constructed a very low cost data storage device from plastic and silicon that can potentially store one hundred megabits of information per square centimeter.
Technology Research News December 3, 2003	Molecule does two-step Duke University researchers have found a way to make a molecule react only when it has been hit by two photons of ultraviolet light, making the molecule a controllable switch. The molecule could eventually be used in optical storage devices and in biochips.
Technology Research News December 3, 2003	Spin material handles heat Researchers from the Royal Institute of Technology in Sweden have doped, or mixed the semiconductor zinc oxide with the metal manganese to make a ferromagnetic semiconductor material that retains its magnetic properties at temperatures as high as 177 degrees Celsius.
