The Search for Weird Life

The search for life in the universe is expanding. A National Academy of Sciences panel is recommending that NASA and the National Science Foundation support searching for forms of life that are different than those which we have experienced. So called weird life would be based on a fundamentally different chemistry than known life forms, silica instead of carbon, arsenic instead of phosphorous or RNA instead of DNA.

Most interesting to me, this weird life could exist on Earth and have been overlooked because it is so unusual.
