How distribution of chemicals affects evolution and astrobiology at the Pavilion Lake Research Project

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 - In the search for life beyond Earth, scientists 'follow the water' to find places that might be hospitable. However, every home gardener knows that plants need more than water, or even sunshine. They also need fertilizer – a mixture of chemical elements that are the building blocks of the molecules of life. Scientists at Arizona State University are studying how the distribution of these elements on Earth – or beyond – shapes the distribution of life, the state of the environment and the course of evolution. See article.
g Life - To approach the empirical question of how far we can test the earliest stages of biological evolution in our own solar system, we should decide first whether we should expect any form of convergence in the exo-microorganisms that we might encounter, possibly close to the surface of icy worlds, such as Europa. See article. Note: This article is from 2003.
g Cosmicus - By using a combination of remotely operated vehicles, autonomous underwater vehicles, SCUBA divers and DeepWorker submersibles, the Pavilion Lake Research Project is blending cutting-edge science and technology to advance our knowledge of astrobiology and to help us learn how to explore with humans on the Moon and Mars. See article.
g Learning - If science communications in astrobiology is about researchers sharing their results, the audience for new findings may well turn out to be a surprising finding in itself. John Horack, one of the principal Internet architects for how a Webby-award winning NASA site found its audience, explains new ways to view the problem of sharing science. See article. Note: This article is from 2004.
