Searching for ETI’s Dyson Spheres and how humanity drove the mammoth to extinction

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 - There are several potential niches for life elsewhere in the universe, as well as terrestrial niches that we consider extreme, that may not be at all extreme from either an evolutionary, or even a physiological point of view. UV radiation tolerance, acidophily (acid lovers), alkilophily (base lovers), thermophily (heat lovers), halophily (salt lovers), and anaerobiosis (oxygen haters) may all be cases in point. SO what the geochemical extremes of salinity and desiccation? See article. This article is from 2005.
g Life - Once thought to be "evolutionary leftovers," new research has shown that ostriches in fact use their feathered forelimbs as sophisticated air-rudders and braking aids. See article.
g Intelligence - A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks. See article.
g Cosmicus - NASA's space shuttle fleet will continue flying through at least early next year due to delays with the agency's final two missions. See article.
g Learning - A 100-foot tall rocket rolled into Houston last week to join the small collection of very large launch vehicles populating the rocket park at NASA's Johnson Space Center. See article.
