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 - What makes Earth habitable? This LiveScience original video explores the science of global warming and explains how, for now, conditions here are just right. See http://www.livescience.com/php/video/player.php?video_id=GoldilocksGreen.
g Life - Reef fish share genetic connections across what Darwin termed an 'impassable barrier', 5000km of deep ocean separating the eastern and central Pacific, according to a report by Smithsonian scientists in the Proceedings of the Royal Society B. See http://www.sciencedaily.com/releases/2006/07/060705184842.htm.
g Intelligence - Animal Controlled Computer Games, a graduation project by Wim van Eck, is a Pac-Man-style game in which humans can play against real insects. The project has been written up in a short paper submitted to the 2006 International Conference on Entertainment. His project parallels part of the plot of “Ender's Game”, the Hugo and Nebula award-winning novel by Orson Scott Card. See http://www.livescience.com/scienceoffiction/

g Cosmicus - Engineers are still assessing the health of two leading edge panels on Discovery's right wing, along with a protruding gap filler just in front of a propellant feedline access door on the orbiter's belly. Mission Management Team Chairman John Shannon said Friday it might take another day or two before engineers can either give Discovery a clean bill of health or show the "regions of interest" represent potentially serious problems.

The Drake Equation
This formula estimates the number of intelligent civilizations in our galaxy.N=(R*)(Ns)(Fp)(Ne)(Fl)(Fi)(Fc)(L)
Where:- N = Number of civilizations we can communicate with
- R* = Average star formation rate
- Ns = Percentage of stars capable of supporting earth-like planets
- Fp = Percentage of those stars with planets
- Ne = Average umber of planets in those stars' habitable zones
- Fl = Percentage of those planets where life begins
- Fi = Percentage of planets with life where an intelligent species evolves
- Fc = Percentage of those intelligent species that develop communication technology
- L = Average lifetime, in years, of a civilization that develops such technology
About Me
- Rob Bignell
- I'm the owner and chief editor at Inventing Reality Editing Service, which meets the editing and proofreading needs of writers both new and published. For more than two decades, I worked as an award-winning journalist, with half of those years spent as an editor. Several of my short stories in the literary and science fiction genres have been published, and I am the author of the nonfiction “Hikes with Tykes” series, a novel "Windmill", and a collection of poetry, "Love Letters to Sophie's Mom". For seven years I worked as an English teacher or a community college journalism instructor. I hold a master's degree in English and a bachelor's in journalism and English.
