Detecting ETI radio leakage and solar system older than we thought

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 - As the sun's energy rises and falls, so goes the Earth's atmosphere, a new study suggests. See article.
g Abodes - Timescales of early Solar System processes rely on precise, accurate and consistent ages obtained with radiometric dating. However, recent advances in instrumentation now allow scientists to make more precise measurements, some of which are revealing inconsistencies in the ages of samples. Seeking better constraints on the age of the Solar System, Arizona State University researchers analyzed meteorite Northwest Africa (NWA) 2364 and found that the age of the Solar System predates previous estimates by up to 1.9 million years. See article.
g Message - A low-frequency search could be a good first step in exploring the lower frequencies for leakage or non-intentional signals from ETI. See article.
g Cosmicus - NEI Corporation and the University of California, San Diego won a Phase II Small Business Technology Transfer contract from NASA to develop and implement high energy density cathode materials for lithium batteries. These lithium-ion (Li-ion) batteries could be used in a variety of NASA projects - and in a wide range of transportation and consumer applications. See article.
g Imagining - Like first contact stories? Then be sure to read David Bischoff’s "The Xaxrling of J. Arnold Boysenberry," anthologized in “First Contact,” edited by Martin H. Greenberg & Larry Segriff (published by DAW, 1997). See article.
