Microalgae are single-cell plants that comprise nature's smallest and most efficient photosynthetic engines: all they need to thrive is water, light, and air.

JAP Materials and APL Materials to join the ranks of AIP's premier journals MELVILLE, N.Y., April 10, 2012 /PRNewswire-USNewswire/ -- Two new open-access journals

Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways.

By adding an incredibly thin coating of alumina to a metal surface, researchers at the Georgia Institute of Technology have doubled the rate that heat travels from a solid surface – such as a pot on a stove – into the liquid in the pot.

Ghost imaging (GI), and its even more oddly named cousin virtual ghost imaging (VGI), seem to contradict conventional wisdom by being able to image an object by simply counting photons in a "light bucket."
