Methane sources on Mars and creating a believable alien species

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - New images of the Nili Fossae region are helping scientists understand unique geological features in the area. Methane in Mars' atmosphere is enhanced over Nili Fossae, leading some scientists to believe that the gas is produced there. The origins of the Mars methane could be geological or perhaps even biological. See article.
g Life - A new book outlines the history, origin and evolution of the nematode, or roundworm. Nematodes have been around for at least 400 million years, play a key role in soil biology and help support much of the planet and animal life on Earth. See article.
g Imagining - No longer can a science fiction writer create a goo-dripping alien just because a story line requires an adversary from another planet to drop in on our unsuspecting world. The average reader is not going to buy into the B-rated movies of old; it takes more than an actor in a rubber mask for them to suspend their disbelief and enjoy a story or novel. Bringing an alien species into a novel requires a bit of planning and thought on the part of the writer. See column.
