One of the most magnificent websites that I have ever seen, ScientificAmerican.com, Unlike all the magazine's website, advertising for their magazine and trying to convince you to pay for the subscription, offers you a widespread range of services on its website; As a matter of fact, the magazine is just a tiny part of their service.
The most interesting part of the website, which I want to present, is the Podcasts section. This part comprises four different categories which are 60-second science, science talk, 60-second earth and 60-second psych.
In 60-second parts you can listen to news or different pieces of information just in one minute. Besides gaining useful info about different aspects of science, earth and psychology, it is of use to English learners, who want to get to know and cultivate their American accent. The concepts are mostly broad and not too technical so that everyone, having general knowledge, can grasp them readily.
Science talk consists of interviews with science experts, but this part, being lengthy, doesn't have scripts and might not be as useful for learners as 60-second parts, in which you can have access to the exact transcript of podcast.
At the end, Scientific American is worth visiting and exploring for either technical and general purposes.
