Technological advances are being made every day, making many of our lives easier and allowing information to be more accessible and available. However for some people, such as the aging population, technological progress can in fact be more limiting. http://www.physorg.com/news176571539.html Medicine & Health Wed, 04 Nov 2009 16:40:01 EST news176571539 (PhysOrg.com) -- Finally, an optical frequency comb that visibly lives up to its name.

For blue light, nitride diodes achieve external quantum efficiencies in excess of 65%, i. e., one photon is emitted for approx. 2/3 of the electron-hole pairs injected into the diode. For red light, phosphor diodes achieve efficiencies of approx. 50%. However, so far no highly efficient monochromatic LEDs have been available for the `yellow gap` at around 560 nm. Now researchers with Philips Lumileds have developed a monochromatic nitride diode that closes this gap. http://www.physorg.com/news167555795.html Physics Thu, 23 Jul 2009 08:17:44 EST news167555795 (PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other type of lighting device is capable of producing this wide a span of sunlight-style illumination, which could make the new technology an attractive future high-quality lighting source. http://www.physorg.com/news166945490.html Physics Thu, 16 Jul 2009 09:00:01 EST news166945490 Variations in how people perceive colors and how those same colors appear on TV, computers and other media have confounded broadcasters, Web designers and printers trying to reproduce lifelike hues. http://www.physorg.com/news165513181.html Other Sciences Mon, 29 Jun 2009 17:10:01 EST news165513181 Kodak is taking Kodachrome away.

While the vitamin is best known for helping build strong bones and absorb calcium, a vitamin D deficiency can raise the risk of everything from immune disorders to colds and flu, according to recent research. http://www.physorg.com/news157295715.html Medicine & Health Thu, 26 Mar 2009 14:15:40 EST news157295715 More and more information is being gathered about how human genes influence medically relevant traits, such as the propensity to develop a certain disease. The ultimate goal is to predict whether or not a given trait will develop later in life from the genome sequence alone (i.e. from the sequence of the bases that make up the DNA strands that store genetic information in every cell of the body). http://www.physorg.com/news155819821.html Biology Mon, 09 Mar 2009 12:20:09 EST news155819821 (PhysOrg.com) -- A University of Arizona research team recently completed a study looking at the DNA blueprint of almost 1,000 individuals and comparing that to detailed measurements of their hair, skin and eye color. http://www.physorg.com/news155239299.html Chemistry Mon, 02 Mar 2009 18:03:01 EST news155239299 (PhysOrg.com) -- Large, perfect diamonds are precious to almost all of us but to some scientists, it is the defects that really matter. This is because defects can form nanoscopic color centers, which play a key role in the development of both quantum computing and quantum cryptography. A research team at the Max Planck Institute for Biophysical Chemistry in Göttingen has now probed these color centers inside the crystal with unprecedented resolution using an optical microscope. Using STED microscopy, the scientists identified even densely packed color centers and determined their position inside the crystal with a precision better than 0.15 nanometers, corresponding to the dimension of an atom.
