Graphene-based system could lead to improved information processing Jun 21st 2013, 13:56 Researchers have proposed a new system that combines ferroelectric materials -- the kind often used for data storage -- with graphene, a two-dimensional form of carbon known for its exceptional electronic and mechanical properties. The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less power-hungry. | New method 700 times faster than the norm for magnifying digital images Jun 21st 2013, 13:55 Scientists have developed new methods for improving two of the most widespread means used in digital image processing: magnification and thresholding. The new algorithm to magnify images stands out not only due to the quality obtained but also due to the time it takes to execute, which is 700 times less than other existing methods that obtain the same quality. | A battery made of wood?
