A comic from a few years ago, that was recently published in an issue of Space Squid (a great nerdy read specializing in sci-fi humor). This comic dealt with bacteria that is constantly forced with the dilemma of killing itself after it asexually reproduces. I think this may be called Parthenogenesis.
When I was living in Ithaca, NY a couple years ago, I was introduced to two physics majors at Cornell University, Robert Hovden and Rob Barton, and over time our love for all things nerd-related brought us to creating a comic together that enabled us to spread our dorky jokes and drawings to a very specific crowd. We worked on it diligently for a few months until we started to produce work we felt confident enough in to mail to magazines. We have just started to get a good amount of responses from 'zines that are happy to print our comics in their pages. We are also currently working on a website where we will upload comics on a more consistent basis. Until then I've included a few samples that have had the fortune of being printed/shown on websites such The Daily Crosshatch and The Cornell Lunatic.
