Looking for ETI in all the wrong places and how ecosystems ‘reset’ after mass extinctions

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 - Supermassive black holes at the hearts of galaxies have phenomenal cosmic jets. So do small stellar black holes. Now a baby star – one that's still forming – has been found to rely on the same mechanism to produce its own jets. See article.
g Life - A new study demonstrates that the extinction of the dinosaurs paved the way for a dramatic increase in the size of mammals. The work provides new information about how ecosystems “reset” after mass extinctions. See article.
g Intelligence - Neuroscientists at MIT and Harvard have made the surprising discovery that the brain sees some faces as male when they appear in one area of a person's field of view, but female when they appear in a different location. See article.
g Message - In pursuit of an answer to that formidable question, scientists have for decades been searching the skies with radio waves to pick up any signs of alien life. They may be looking in the wrong place. See article. This article is from 2004.
