Clues about planet-forming processes, new dino killer fingered and best time to pick up a broadcast from intelligent aliens

Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Abodes - Observations and models for extrasolar planet formation can be compared with clues about planet-forming processes in the Solar System to answer the question: how typical are the processes that formed our Solar System? See article.
g Life - Instead of being driven to extinction by death from above, dinosaurs might have ultimately been doomed by death from below in the form of monumental volcanic eruptions. See article.
g Message - Our best chance of picking up a broadcast from intelligent aliens is when the Earth is closest to being directly between our Sun and the transmitting alien star. See article. Note: This article is from 2002.
