Time, Newsweek, Popular Science, and other magazines serve the purpose of summarizing your topic. This is reporting, not scholarly research. Look through theses articles for names of researchers and institutes that are working on the project. These names may help you narrow your topic if there is too much information. These articles often include useful websites, but these are frequently are biased in one direction or another. Corporate or product websites are biased in favor of the company. Trade journals cover the news of particular industries and the latest technological developments. Scholarly articles can review the literature, comment on the research, and report the latest research and developments. These articles will tell you what the engineering world is doing. These are starter databeses for these levels of information. Your research for engineering classes should not stop here.
