Hey,

I'm looking for a magazine, a website or other, where new achievements or opportunities are presented.

Well, let's say this: in principle everything is interesting, (at least for me) any new development, including breakthroughs or other. New things that came up or new ideas ...
I'm really interested in many aspects, but especially on the technical side, as may soon be usable new technologies, no matter what aspect (weapons, robotics, aerospace, automotive, motors, ...) but also things like medicine (new drugs, treatment options, implants) well, so almost everything in the natural sciences area.
However, I do not care about any gossip magazines or something like that, it just has to be serious.

Thanks in advance for any replies
