Is there a single scientific publication aimed at a general audience which does not tend towards triviality or nonsense? If so, what is the foremost example?

SciAm used to fill that niche; serious science, by serious scientists or good science journalists, explained for, and entertaining, the everyman.

What I'm seeing now is not serious or good or science.

Agreed. I have attempted to contact them multiple times and asked them to stop this. They never reply. They've turned 180 degrees from what they used to be. I've not researched this but I assume they must have been acquired by somebody.

Or entertaining.

I recommend Science News. It tends to follow conference proceedings and journal articles, and seems to weed out most of the crap news.

That means that the top news is often not all that important -- it's not as if earth-shaking discoveries happen every week. But it means that what they report is true and given the appropriate emphasis. They're trying to inform you rather than thrill you.

Probably IEEE Spectrum?

Knock on wood.
