Although this doesn't really count as a science fiction invention, I can't resist the following video, which is both graphically interesting and clever in a way that sf fans can appreciate.
(Tyson, Superman, Krypton, Action Comics)
Tyson, the director of the Hayden Planetarium at the American Museum of Natural History and a generally awesome human, has a cameo in Action Comics No. 14, out Wednesday. In the comic, he helps Superman find Krypton on its final day in the universe. In order to get that location, and because he’s (again) awesome, Tyson and a team of scientists actually located a planet with Krypton-like characteristics.
I wouldn't have thought I had very many Superman-related stories lying around the site, but after you've done 3,800 science fiction in the news stories, you've probably got a few:
