Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - New research, published in the Astrobiology journal, reveals that life might actually be able to survive on some of the many strange exoplanetary bodies. See article.
g Life - Johns Hopkins scientists report what is believed to be the first evidence that complex, reversible behavioral patterns in bees - and presumably other animals - are linked to reversible chemical tags on genes. See article.
g Intelligence - Positive emotions like joy and compassion are good for your mental and physical health, and help foster creativity and friendship. But people with bipolar disorder seem to have too much of a good thing. In a new article to be published in the August issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science, psychologist June Gruber of Yale University considers how positive emotion may become negative in bipolar disorder.

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
