[4] In years past, nine cartoon characters, known as the Muses, appeared in the margins throughout the magazine as well as in the Kokopelli & Company comic strip.

[8] Past issues have included articles about vegetarianism, pie throwing, extraterrestrial life, naked mole-rats, the origin of the Moon, pirates, urban legends, insects, mummies, tenrecs, New Zealand's exploding trousers, Rube Goldberg inventions, The Lord of the Rings, and blind cavefish.

Among them, only Urania was one of the original Greek muses; Kokopelli, a trickster, is a god in many Native American tribes.

In addition, Devil, Kokopelli's dog, and Angel, Mimi's cat, were occasionally featured, more so in older issues.

As of September 2015, the Muses have been removed from the magazine, replaced with a new comic called "Parallel U" drawn by Caanan Grall.
