This simple broad based pipe pulls stories from 65 sources, like Scientific American, ScienceDaily, NewScientist, NSF, Eurekalert, TomsHardware, IEEE, EIN, Telegraph & BBC. The focus is on Science, Technology, Physics, Neurology, Computers and Nanotechnology. The filters drop most political, social network, music device, climate and sales/shopping stories. Duplicate stories are culled and the rest is sorted alphabetically. User may input desired timeframe; otherwise, it defaults to the last 26 hours. There is plenty of room to add additional news sources or filters.
