Well, I thought that Science 2.0 would be enough for my needs, whatever that means. But then I found Science 3.0, made probably because 2.0 was already taken. Science 3.0 has different aims, it is not about outreach, but about collaboration between scientists. Intersting, but one can safely say in its starting phase. But then - when typing science3 in the address field of the browser, the thing suggested science360, with no numerical points - http://science360.gov/Science is never out of style and there's never a "final frontier".
So I visited
science360, there are many videos there. There are also news there.
