Quantum Dots That Produce White Light Could Be The Light Bulb's Succes
Coat a blue LED with a thin layer of microscopic beads called quantum dots of a particular size and the resulting hybrid LED gives off white light, similar to that produced by an incandescent lamp. The discovery that quantum dots can spontaneously produce white light in addition to a rainbow of individual colors could hasten the day when conventional lights are replaced by more efficient and more durable solid state lighting. NIST Method Improves Reliability Of GPS Clocks
A statistical method, developed by the National Institute of Standards and Technology (NIST) and tested and implemented with the help of several collaborators, has made the job of analyzing the accuracy and reliability of Global Positioning System time signals significantly faster and easier. The method will help ensure that GPS clocks produce accurate location and distance measurements and remain closely synchronized with official world time.
Sony PFR-V1 Personal Field Speakers (aka Headphones) Look Cooler Than
Sony's new headset looks great, but doesn't perform very well for most kinds of music. Gallery: Deep-Space Art
A new exhibit translates out-of-this-world radio signals into abstract visuals. Marines Use MySpace to Recruit
High school campuses must not yield enough catch -- the latest military recruiting tactic has the U.S. Marine Corps trawling the MySpace community looking for young converts. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. 3-D Seismic Technology Locates Natural Gas In Fractured Reservoirs
Large volumes of natural gas are being tapped from the tight rocks of the San Juan Basin in New Mexico's Rio Arriba County using a new technology developed in a project sponsored by the U.S. Department of Energy (DOE). Abandoned Bones Suggest TB Wiped Out Leprosy In Battle Of Killer Disea
The spread of tuberculosis may have killed off leprosy in Europe in the Middle Ages, according to research published in the latest issue of the Royal Society Proceedings B. Advance Helps Explain Stem Cell Behavior
Biochemists at Oregon State University have developed a new method to identify the "DNA-binding transcription factors"that help steer stem cells into forming the wide variety of cells that ultimately make up all the organs and parts of a living vertebrate animal. The research is an important step towards understanding stem cell behavior and how cellular development is controlled. Diagnosis By Patterned Paper: Photoprinted Paper Supports Simultaneous
G. Whitesides and his team at Harvard University have developed a prototype for an inexpensive, highly practical rapid test that can be used to carry out several biological tests simultaneously on a single drop. As they describe in the journal Angewandte Chemie, their tests are based on tiny pieces of paper onto which defined, millimeter-sized channels are printed.
