Antimatter has been in the news lately since the ALPHA team at the European Organization for Nuclear Research (CERN) announced 38 antihydrogen atoms were trapped for about a sixth of a second, long enough to be studied.
It's a small step to reaching the levels of antimatter use in science fiction, but the world has a very long way to go. The amount of antimatter created is nowhere near the level needed to power space ships like those of science fiction. There's a good article by Mark Whittington on Yahoo! News called "Antimatter Rockets in Science Fiction" that discusses this. Click here for the article.
I also came across this video of Jeffrey Hangst, spokesperson of the ALPHA experiments and a physicist at the University of Aarhus. He talks about how the antimatter-creation process works. He's fairly technical but gives a lot of information. Below is the video.
