Verifying potential ETI signals and volcanoes destroyed Neanderthals

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 - Cassini has been monitoring clouds on Saturn's moon Titan since the spacecraft entered orbit. Now, scientists have released the first long-term study of Titan's weather. Studying Titan is of interest to astrobiologists because some scientists have theorized about the potential for unique life on the dynamic moon. See article.
g Life - Researchers at the University of California, Santa Cruz, have found that a species of lizard in the Mojave Desert lives in family groups and shows patterns of social behavior more commonly associated with mammals and birds. Their investigation of the formation and stability of family groups in desert night lizards (Xantusia vigilis) provides new insights into the evolution of cooperative behavior. See article.
g Intelligence - New research suggests that climate change following massive volcanic eruptions drove Neanderthals to extinction and cleared the way for modern humans to thrive in Europe and Asia. See article.
g Message - Most SETI programs scan the sky looking for strong radio signals. Any signals that are deemed interesting are put on a list for follow-up observations weeks, months — even years later. Long delays in verification of potential ET signals sometimes generate tantalizing, but ultimately frustrating, stories. See article. This article is from 2003.
g Cosmicus - China has successfully launched their second robotic mission, named Chang'E-2. The satellite is scheduled to reach the Moon in five days, where it will collect high-resolution imagery of future landing sites for China's Chang'E-3 lunar rover. See article.
