First 'One-way Roads' For Light Could Lead To Simpler Lightwave Technology Oct 10, 2009
"Loosely speaking the waveguide acts as a perfect cloak of the defect or obstacle in the path of the light" said Professor Joannopoulos, "the only difference is a phase shift of the guided light.". While the focus of the present work is in the microwave regime, in conventional optics, light reflections present a major roadblock to light-driven circuits reaching the same level of sophistication as widely used microelectronic circuits.

Ouchless wildlife plague vaccine, shipwrecks and coral reefs and more Aug 4, 2009
Coral reefs can undergo fast changes in their dominant life forms, a phenomenon referred to as phase shift. Scientists have speculated on many possible causes of phase shift, but this study is the first one to clearly show that a rapid change in the dominant life forms on a coral reef is associated with man-made structures ... Even though phase shifts can have long-term negative effects for coral reefs, eliminating organisms responsible for phase shifts can be difficult, particularly if they... (EurekAlert!)

"The homogenous infusion of nanoparticulate causes the bait to exhibit a unique spectral phase shift when subjected to the simultaneous combination of water and light.". That is enough to make your eyes glaze over. (ESPN -- Outdoors)
Tech revolution: Innovation is the key Jun 16, 2009
Cool Clean's phase shift liquid carbon dioxide extraction technology could remove the oil without relying on fossil fuels and damaging the environment. This technique also theoretically allows people to convert the leftover algae into high-end animal feed. (Bismarck Tribune, ND)
In The Turf War Against Seaweed, Coral Reefs More Resilient Than Expected Jun 4, 2009
Researchers also found overall "phase shift severity" decreased in the Caribbean, did not change in the Florida Keys and the Indo-Pacific, and increased slightly on the Great Barrier Reef due to moderate coral loss ... Said Sweatman: "I hope this study leads to clearer definition of what coral-algal phase shifts are and broadens our perspective on the serious loss of corals in many parts of the world. Australian reefs have been relatively lucky so far, but there is no reason for complacency.". (Science Daily)
Supercooled Silicon: Liquid-liquid Phase Transition In Silicon Confirmed Mar 23, 2009
Like water, it has been hypothesized that supercooled silicon liquid silicon that has its temperature lowered to below the freezing point without crystallizing and becoming a solid experienced a liquid-liquid phase shift ... The computations revealed that a liquid-to-liquid phase shift, evidenced by the presence of a van der Waals loop, occurred when silicon was supercooled to 1200 degrees Kelvin; silicon normally freezes at 1700 degrees Kelvin.

Materials Science Mystery Of 'Hidden Order' Solved: How A New Phase Arises And Why Feb 24, 2009
There are several materials that evince a clear phase shift in all thermodynamic properties when the temperature falls below a certain transitional temperature, but no one has been able to explain the new collective order in the material. Until now, it has been called the hidden order. (Science Daily)
Freescale's Su: Simplify DFM Feb 24, 2009
Among the elements in ''litho-induced complexity'' include optical proximity correction (OPC), phase shift masks, and, more recently, source-mask optimization (SMO). SMO is an element of computational lithography, which is geared for the 22-nm node. (EETimes)
