Scientific American today
Still the best printed source of science news for the general public. It's certainly not the serious scientific journal it was in its heyday, nor even the definitive layman's resource for developments in science that it was before the Web took the wind (and the advertisers) out of print journalism's sails. But if you want to stay current on the state of cosmology, physics, and biology via a format you can roll up or easily view two pages at a time, there are no better options.
