Are plasma crystals alive? Cosmic dust can, in the presence of plasma, creates formations known as plasma crystals. An international team of researchers published a study in the Aug.14, 2007, issue of the New Journal of Physics (PDF here, abstract here) that indicates that these crystals may be more sophisticated than anyone realized. In simulations involving cosmic dust, the researchers witnessed the formation of plasma crystals displaying some of the elementary characteristics of life -- DNA-like structure, autonomous behavior, reproduction and evolution.

For most of us, science arrives in our lives packaged neatly as fact. But how did it get that way? Science is an active process of observation and investigation. Evidence: How Do We Know What We Know? [HTML version, Flash version also available] examines that process, revealing the ways in which ideas and information become knowledge and understanding. In this case study in human origins, the folks from the Max Planck Institute for Evolutionary Anthropology explore how scientific evidence is being used to shape our current understanding of ourselves: What makes us human—and how did we get this way?
