Technology Research News November 5, 2003 Eric Smalley	Crystal bends light back Being able to bend light backwards is extremely useful. This negative refraction is controversial in physics circles and has only been demonstrated using artificial materials containing metal loops. It turns out that a common natural crystal has harbored this capability all along.
Technology Research News November 5, 2003	Electrons spin magnetic fields Spintronics researchers are looking for ways to control and use electron spin. Researchers from Cornell University and Yale University have brought the field a step forward by showing that a flow of electrons that all have the same spin can transfer angular momentum to magnetic material.
Technology Research News November 5, 2003	Paired molecules store data Researchers from the University of California at Irvine have bonded a pair of molecules to form a molecule that has two states. The components are photochromic fulgimide and a dye molecule capable of florescence.
Technology Research News October 8, 2003 Kimberly Patch	Crystal slows and speeds light Playing tricks with light -- speeding, slowing and storing it -- is becoming a popular pastime among physicists. The effects could eventually be used to improve communications and data storage and help bring about quantum computing and quantum communications.
Industrial Physicist Eric Lerner	Briefs Penetrating the fog... Plasma self-organization... Stronger than spider silk... Slow light... etc.
Industrial Physicist	Reprise: Spin and Energy - Free? The news brief published in August/September drew quite a few reader letters.
Technology Research News September 24, 2003 Eric Smalley	Laser made from single atom The simplest possible laser -- a single atom -- has been on the drawing board for decades. Researchers have finally achieved the extremely precise control needed to make a laser from just one atom. The first demonstration of a single-atom laser showed that it's a different animal -- it produces quantum light.
Industrial Physicist Aug/Sep 2003 Eric R. Mueller	Terahertz radiation: applications and sources Today, with continuous-wave (CW) and pulsed sources readily available, investigators are pursuing potential terahertz-wavelength applications in many fields.
Wired August 2003 Michio Kaku	A User's Guide to Time Travel All it takes is a grasp of theoretical physics, control of the space-time continuum, and maybe a ball of cosmic string.
Industrial Physicist Rubin & Poate	Ion implantation in silicon technology Ion implanters are essential to modern integrated-circuit (IC) manufacturing. Doping or otherwise modifying silicon and other semiconductor wafers relies on the technology.
