How about the obvious,
Science Magazine?

(From the publishers of
Science, the journal).
Physics Today (published by the APS) is the only one I read regularly. It's a great, general-physics exposition of interesting research, a lot of which is very relevant to real life ("Thermodynamics of Hurricanes", "Stability of Bicycles"). Then, there is a lot of general-audience science news in the first 20-30 pages of both
Science and
Nature, which are presitigious journals of a very broad scope.
After those, there are two decent popular magazines,
Discover, and
Scientific American. SciAm is somewhat inconsistent in quality, especially when they venture into theoretical physics; there they aim to impress and entertain, rather than inform.
Popular Science is mainly technology-oriented, so I won't mention it.
Finally you get sensationalist drivel like
New Scientist, which is a "non peer-revied journal" (

) and a regular forum for crackpottery.
