Examining Antarctica to understand alien worlds and advertising our presence to ETI

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 - The Hot Zone recently discussed ocean acidification and what it could mean for the future climate of Earth. Earlier this month expert panels organized by the United Nations discussed ocean acidification and the future of Earth's marine ecosystems. See article.
g Life - There's not much in the ice-covered lakes in the McMurdo Dry Valleys to interest anglers looking to land the big one. But for scientists who want to know more about some of Earth's earliest organisms - and, by extension, to recognize what life may look like on other planets - those unique ecosystems represent a useful portal to the past. See article.
g Message - Just how does SETI work? Here’s a good primer for those looking to get a basic overview.
g Cosmicus - At times, NASA's attempts to launch a new Ares I-X rocket Tuesday seemed surreal — with bad weather, a stuck sensor sock and a wayward cargo ship offshore appearing to conspire to prevent the booster's liftoff. But believe it or not, there have been stranger things to pop up in NASA's launch history. See article.
g Aftermath - It is sometimes said that the best form of advertising is education. But what products would our global marketplace tolerate at the borders of an encounter with another, perhaps far different civilization? To get some perspective, an expert entertains the question of how to advertise our presence to a more universal demographic. See article. Note: This article came out in 2004.
