Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - Researchers have resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli bacteria. The experiment is helping scientists observe evolution in action. See article.
g Intelligence - The diet of Australopithecus anamensis, a hominid that lived in the east of the African continent more than 4 million years ago, was very specialized and, according to a scientific study whose principal author is Ferran Estebaranz, from the Department of Animal Biology at the University of Barcelona, it included foods typical of open environments (seeds, sedges, grasses, etc.), as well as fruits and tubers. See article.
g Cosmicus - Research on the behavior of foams in microgravity has caught the attention of private industry. After performing experiments on parabolic flights, low-Earth orbit could be the next step in studying the science of foams. See article.

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
