How to get oxygen in your atmosphere and invading aliens

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 - A switch from predominantly undersea volcanoes to a mix of undersea and terrestrial ones shifted the Earth's atmosphere from devoid of oxygen to one with free oxygen, according to geologists. See article. Note: This article is from 2007.
g Life - Extraterrestrial life is life originating outside of the Earth. It is the subject of astrobiology and its existence remains hypothetical, because there is no credible evidence of extraterrestrial life which has been generally accepted by the mainstream scientific community. See article.
g Intelligence - A research team has discovered a part of the brain crucial for counting and performing arithmetic. The new finding could lead to a better understanding of dyscalculia, a psychological disorder that makes it nearly impossible to deal with numbers, much less complicated math. See article. Note: This article is from 2006.
g Cosmicus - Quote of the Day: " our obsession with antagonisms of the moment, we often forget how much unites all the members of humanity. Perhaps we need some outside, universal threat to make us recognize this common bond. I occasionally think, how quickly our differences worldwide would vanish if we were facing an alien threat from outside this world." — President Ronald Reagan, United Nations General Assembly, (Sept. 21, 1987)
g Learning - Here’s a neat new set of afterschool activities for elementary school students: “Astrobiology.” This new resource guide from the American Museum of Natural History brings astrobiology activities to the afterschool arena. As part of an 18-month project, AMNH collected NASA materials originally developed for the formal education setting, and adapted them for use in afterschool programs for participants aged 5-12. Members of NAI's NASA Ames Research Center Lead Team served as science advisors to the guide.
g Imagining - What about the invading aliens from the X-Files: Are they plausible? A book released a few years ago that addresses the topic is “The Science of the X-Files” by Jeanne Cavelos.
