In the science-fiction/fantasy genre, most recent was IDW's 4-issue series of "Phoenix Without Ashes"; done true to the original story, and NOT the terrible attempt that Canada did for TV in the '70s!
Also, the Logan's Run series "Lastday" and "Aftermath" from Blue Water comics.
Otherwise, I still have quite a few 2000AD, Judge Dredd, and Robo-Hunter comics (both originals and reprints, dated back to the mid '80s).
And though not sci-fi, MAtt Wagner's "Mage" trilogy, and his Batman/Grendel and Dredd/Batman crossover comics...
