Technology Research News November 3, 2004	Photonic Crystal Lasers Juiced Researchers have made a photonic crystal laser that is driven by electric current. The device could eventually be used as a source of single photons for quantum cryptography and communications devices.
Technology Research News November 3, 2004	Lasers Move Droplets Labs-on-a-chip promise inexpensive and portable biological and chemical analysis. The key to making the tiny labs work is finding ways to move and mix minuscule amounts of substances.
Technology Research News October 20, 2004	Crystal links ultraviolet photons Researchers from Tohoku University in Japan have moved the quest to control entanglement forward with a method that uses the energy from a pair of photons to produce a pair of entangled photons that have the same energy state as the original photons
Geotimes October 2004 Naomi Lubick	Dynamo in a Box Dan Lathrop is building a planet in his lab. If everything goes as planned, his 3-meter-tall metal sphere will self-start its very own dynamo, a process where heat and motion establish a magnetic field.
Technology Research News October 6, 2004	Gas flow makes electricity Gas flows at speeds as low as a few meters per second over semiconductor materials and carbon nanotubes have produced electricity. The phenomenon could lead to small, inexpensive, accurate gas flow sensors in less than two years, according to the researchers.
Industrial Physicist Oct/Nov 2004 Eric J. Lerner	News Democrats & Republicans: What's the record on physical science?
Technology Research News September 22, 2004 Eric Smalley	Bank Transfer Demos Quantum Crypto As quantum cryptography nears practical application, researchers are working on the next generation of the technology, which includes the weird quantum phenomenon of entanglement.
InternetNews September 2, 2004 Susan Kuchinskas	Scientists Set Internet2 Speed Record Caltech, CERN transfer seemingly inconceivable amounts of data at blazing speed. The feat will help boost science and commerce.
Technology Research News August 25, 2004 Eric Smalley	Five Photons Linked Researchers have entangled five photons - a key step in quantum computing which would make it possible to check computations for errors and teleport quantum information within and between computers.
Technology Research News August 25, 2004	Photosynthesis Drives Solar Cell Researchers have mixed biology and electronics in solar cells that use photosynthetic spinach leaf molecules or photosynthetic bacteria to convert light to electricity.
