A new research and training facility at Imperial that will construct DNA at industrial levels has been announced today by the Universities Minister. Designing‚ constructing and testing DNA is a crucial element of synthetic biology‚ an area of science which combines biology and engineering to create new biologically based devices that will help solve a range of different global challenges. These devices are made from harmless cells‚ such as yeast cells. Manmade yeast genes could then be used to

Beauty contests are bad for body image • Beauty competitions‚ or as some people call them‚ beauty pageants‚ degrade women and present a bad body image.

GRAPHICAL PASSWORD AUTHENTICATION WITH SOUND INTEGRATION ABSTRACT: Here‚ a graphical password system with a supportive sound signature to increase the remembrance of the password is discussed. In proposed work a click-based graphical password scheme called Cued Click Points (CCP) is presented. In this system a password consists of sequence of some images in which user can select one click-point per image. In addition user is asked to select a sound frequency or time which he wants to be played
