London, Apr 30 : Buying an e-reader but not sure if you''d like reading the dim screen? Well, then get ready for e-book reading experience that will be as close to printed media as possible.

Scientists have announced, what is known as Electrofluidic Display Technology (EFD)- the first technology to electrically switch the appearance of pigments in a manner that provides visual brilliance equal to conventional printed media.

The work by an international collaboration of the University of Cincinnati, Sun Chemical, Polymer Vision and Gamma Dynamics, could offer better than 85 percent "white-state reflectance."

Washington, Apr 30 : Humans have an inherent ability to recognize faces and other objects with just a glimpse, and now researchers have found that this ability to visually process images is much faster than it is believed.

Taking advantage of brain mapping in patients about to undergo surgery for epilepsy, researchers at Children''s Hospital Boston, have for the first time showed that the brain, at a very early processing stage, can recognize objects under a variety of conditions very rapidly.

Washington, April 30 : Scientists have used a genome engineering tool they developed to make a model crop plant herbicide-resistant without significant changes to its DNA, which could help provide sustainable food, fuel and fiber.

The research team was from the University of Minnesota and Massachusetts General Hospital in the US.

Washington, April 30 : Engineers at the Ohio State University, US, have designed control system software that can effectively guide a hypersonic experimental "scramjet", which is faster than the speed of sound.

Government agencies have been developing faster-than-sound vehicles for decades.

The latest supersonic combustion ramjets, called scramjets, burn air for fuel, and could one day carry people to space or around the world in a matter of hours.
