    A quick summary: Silica deposits in the Gusev crater that look like small cauliflowers are theorized to have been formed by microbes, indicating the presence of life on mars.

    And a few notes:

    - while on earth microbes are known to form such deposits, this might be a naturally-occurring phenomenon

    - the presence of microbes in the past to shape the deposits does not imply any current life

    - of course, further study is needed; the Gusev crater is on the short-list for landing sites for NASA's 2020 mars rover
