Earth-sized planet may be diamond world

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 - New research suggests that a rocky planet twice the size of Earth and orbiting a nearby star is a diamond planet. It may be the first glimpse of a rocky world with a fundamentally different chemistry than our own planet. See article.
g Life - A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions - that survival is based on a change's functional advantage if it is to persist. Stuart A. Newman, Ph.D., professor of cell biology and anatomy, offers an alternative model in proposing that the origination of the structural motifs of animal form were actually predictable and relatively sudden, with abrupt morphological transformations favored during the early period of animal evolution. See article.
g Message - Two new research grants are supporting projects that bleed into science fiction. The first could help identify advanced civilizations powered by massive, orbiting solar power stations. The second study will look for ways of detecting universes other than our own. See article.
