Thirty million year old ice age and using cellulose microfibers to find extraterrestrial life

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 - New research shows that a 'brief' ice age in Earth's past actually lasted for 30 million years. During the ice age, global warming was curbed by the natural burial of organic carbon underground. The study is helping scientists understand the historical connections between the biosphere and the environment of Earth. See article.
g Life - A new study shows that abundant cellulose microfibers are present in t250 million year old halite and appear remarkably intact. This discovery points to cellulose as an ideal macromolecular target in the search for life on other planets in our Solar System. See article.
g Cosmicus - As the 21st century gets underway, the impact of space activities upon the welfare of humanity only will increase. See article.
g Learning - Here’s a neat Web site courtesy of NASA: “Future Flight Design”. Written for grades 3-7, kids can design air transportation and aircraft systems.
