g Abodes - How did the Earth stay warm 3.8 billion years ago when the young sun was 30% weaker? It's a mystery scientists have long been trying to solve, and it may come down to global warming. Ancient warming on Earth can also provide important clues concerning modern climate change. See article.
g Message - Should we modify the Drake Equation to account for civilizations which actually engage in deliberate interstellar transmission? See article.
g Imagining - Is there life on other planets? If so, does it look like the monstrous thing Sigourney Weaver battled in the “Alien” movie blockbusters? Could you kiss it the way Captain Kirk was so fond of doing on “Star Trek”? Or, could it be related to your houseplant? See article.
