How world’s axial tilt might prevent life and facial evolution

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 - Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into 'red and dead' elliptical galaxies, catching a large group of galaxies right in the middle of this change. See article.
g Abodes - Gravitational interactions between red dwarf stars and habitable planets could erase a world's axial tilt, which moderates global temperatures and creates seasons, before life gets a chance to develop. See article.
g Life - Scientists have revealed details about the life that inhabits one of the world's most extreme deep-sea volcanic vents. See article.
g Intelligence - UCLA biologists working as "evolutionary detectives" studied the faces of 129 adult male primates from Central and South America, and they offer some answers in research published Jan. 11, in the early online edition of the journal Proceedings of the Royal Society B. The faces they studied evolved over at least 24 million years, they report. See article.
g Cosmicus - New maps produced by the Lyman Alpha Mapping Project aboard NASA's Lunar Reconnaissance Orbiter reveal features at the Moon's northern and southern poles in regions that lie in perpetual darkness. See article.
