How long-duration space travel affects living organisms and the fictional alien seaswallower

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of Ez Aquarii ABC, a star about 11 light years from Earth? See article.
g Abodes - Earth's magnetic field has flipped its polarity many times throughout history. Based on geologic and fossil records, it seems that such a polarity reversal would have no dramatic effects for life on Earth. See article.
g Cosmicus - New research shows that in space, a microscopic worm develops from egg to adulthood in the same way as it does on Earth. The results could help astrobiologists understand how long-duration space travel affects living organisms. See article.
g Imagining - In Prof. Joan Slonczewski’s “Biology 103: Biology in Science Fiction” class at Kenyon College, her students, using astrobiological principles, attempted to create a number of plausible alien civilizations and worlds as a class project. Here’s one, called the seaswallower.
