Tool use by a fish
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 - What is the potential habitability of the nearby star system Gliese 570? See article.
g Life - Scientists have captured the first video of tool use by a fish. The orange-dotted tuskfish was caught on film throwing a clam against a rock to crush it. Tool-use may be a deep-seated behavioral trait that evolved in wrasses, one of the largest and most diverse families of marine fishes. See article.
g Aftermath - In its simplest and shortest definition, astrobiology may be summed up as, “The study of life in the universe.” There's just one problem when it comes to studying life in the universe. So far, we're it.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
