g STARS - Only recently has the idea of habitable planets around red dwarf stars taken hold. But it's a fascinating one, especially if you take a look at the potential window for life to develop on such worlds. M-class red dwarfs live anywhere from 50 billion up to several trillion years, a vast stretch compared with our own Sun's projected ten billion years. And with 75 percent of main sequence stars thought to be red dwarfs, the hunt for life can be expanded enormously if we add red dwarfs to the mix. See article.
g ABODES - Researchers are studying life in an extreme environment not typically known for extremes. The dense, salty water of sinkholes in Lake Huron supports bizarre ecosystems composed of purple cyanobacteria mats and other strange microorganisms. See article.
g MESSAGE - Extraterrestrial civilizations may find it more efficient to communicate by sending material objects across interstellar distances rather than beams of electromagnetic radiation. See article. Note: This article is from 2004.
