‘Intelligent Life in the Universe’ and technological manifestations that would make an advanced extraterrestrial civilization detectable

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 Intelligence - Book alert: “Intelligent Life in the Universe”, by Peter Ulmschneider, addresses all scientists and others interested in the origins, development and fate of intelligent species in the observable part of our universe. In particular, the author scrutinizes what kind of information about extraterrestrial intelligent life can be inferred from our own biological, cultural and scientific evolution and the likely future of mankind. The first part of the book provides the necessary background information from space and life sciences, thus making the book also accessible to students and the scientifically educated public.
g Message - What technological manifestations would make an advanced extraterrestrial civilization detectable? See article. Note: This paper was written in 1992.
g Cosmicus - Long-term thinking is always a tough sell, particularly in an age as frenetic as ours, but missions like EPOXI fit into the gradual accretion of exoplanetary knowledge that will build the foundation for far more remarkable discoveries. See article. Note: This article is from May 2008.
g Learning - To be sure, researchers have long studied the origins of life on Earth and searched for signs of it on other planets. But until recently those enterprising scientists lurked at the fringes of their fields. No longer. See article. Note: This article is from 2004.
