Invader star clusters and ETI behavior

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 - As many as one quarter of the star clusters in our Milky Way - many more than previously thought - are invaders from other galaxies, according to a new study. The report also suggests there may be as many as six dwarf galaxies yet to be discovered within the Milky Way rather than the two that were previously confirmed. See article.
g Abodes - Though comets are thought to be some of the oldest, most primitive bodies in the solar system, new research on comet Wild 2 indicates that inner solar system material was transported to the comet-forming region at least 1.7 million years after the formation of the oldest solar system solids. See article.
g Life - Fossils of a previously undiscovered species of dinosaur have been found in slabs of Utah sandstone that were so hard that explosives had to be used to free some of the remains. See article.
g Intelligence - UCLA's Jeffrey Brantingham works with the Los Angeles Police Department to analyze crime patterns. He also studies hunter-gatherers in Northern Tibet. If you tell him his research interests sound completely unrelated, he will quickly correct you. See article.
g Cosmicus - Princeton engineers have made a breakthrough in an 80-year-old quandary in quantum physics, paving the way for the development of new materials that could make electronic devices smaller and cars more energy efficient. See article.
g Aftermath - What role will extraterrestrials play in humanity’s future? Click here for a paper by University of Toronto Professor Allen Tough. Though written almost 20 years ago, the paper contains plenty of useful ideas that are fresh (and ignored) today, especially those about extraterrestrial behavior and help.
