Is ET out there, capable of phoning home?

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 new study shows that Earth's core formed in the presence of more oxidizing conditions than previously thought. The study is helping scientists understand the distribution of planet-forming materials in the early Solar System. See article.
g Life - A new study shows that multicellular cyanobacteria arose much earlier than previously believed. Multicellularity developed in cyanobacteria at almost the same time as the oxygenation of Earth's atmosphere, and around one billion years earlier than eukaryotes. See article.
g Intelligence - Microbes on Mars might be impressive, but the average Earthling would really be wowed by news of a full-blown, advanced civilization on a planet beyond our own. What’s the likelihood that such a civilization exists in our galaxy? Explore the arguments over whether ET is out there, capable of phoning home. See article.
