Looking for ETI using near-infrared laser communications and intriguing times in the exploration of other solar-system bodies

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - Genetic information from an extinct species of bison preserved in permafrost for thousands of years could help improve modern agricultural livestock and breeding programs. See article.
g Message - What are the advantages of looking for ET using near-infrared laser communications? There’s a good explanation at a University of Kentucky Web site.
g Aftermath - These are intriguing times in the exploration of other solar-system bodies. Continuing discoveries about life on Earth and the return of data suggesting the presence of liquid water environments on or under the surfaces of other planets and moons have combined to suggest the significant possibility that extraterrestrial life may exist in this solar system. Similarly, not since the Viking missions of the mid-1970s has there been as great an appreciation for the potential for Earth life to contaminate other worlds. Current plans for the exploration of the solar system include constraints intended to prevent biological contamination from being spread by solar-system exploration missions. See article.
