g ABODES - A new study of how climate conditions have affected the origin and evolution of life on Earth could provide clues to understanding how climates on alien planets might affect their potential for life. See article.
g INTELLIGENCE - It is inevitable. The muscles weaken. Hearing and vision fade. We get wrinkled and stooped. We can't run, or even walk, as fast as we used to. We have aches and pains in parts of our bodies we never even noticed before. We get old. It sounds miserable, but apparently it is not. A large Gallup poll has found that by almost any measure, people get happier as they get older, and researchers are not sure why. See article.
g MESSAGE - Its one thing to search for intelligent aliens, but it's another to actually talk to those we might find. This isn't just a matter of what language (if any!) to use, or even how to encode the information. Encoding for mutual understanding is merely a daunting technical challenge. For example, should we broadcast messages using pulse code modulation, AM radio, spread-spectrum techniques, or something we don't have a name for yet? Until we pick up a signal, we really haven't a clue. See article. Note: This article is from 2001.
g LEARNING - "How does the physical and biological world change over time? What causes these changes and how fast do they occur? What is the evidence for change in living and physical systems?" These are core questions posed in "Voyages through Time," a high school science curriculum from the SETI Institute that challenges students to consider the origin and development of the universe, our solar system, life on Earth, and us. See article. Note: This article is from 2003.
g AFTERMATH - Would dutiful American citizens trust the government to handle first contact with extraterrestrials and rush to get information to the public? See article. Note: This article is from 1999.
