Looking for Spanish content - something about natural science

As the title says.
I have read the GEO magazine in Spanish, but it was a little bit difficult.The content on LingQ, however, seems to easy, even the advanced things Unfortunately there is no Spanish online version of GEO. I thought about reading wikipedia content (random stuff about science), but apart from that, does anyone have a good magazine / blog which covers similar topics? I would appreciate it!
