I Sing the Body Electric by Walt Whitman, certainly applies to newly discovered microbes that eat electricity in hostile habitats that truly boggle the mind. With this in mind, pardon the pun, it seems more than reasonable that life abounds everywhere given just how tough these organisms truly are.
Though eating electricity seems bizarre, the flow of current is central to life. All organisms require a source of electrons to make and store energy. They must also be able to shed electrons once their job is done. In describing this bare-bones view of life, Nobel Prize-winning physiologist Albert Szent-Györgyi once said, “Life is nothing but an electron looking for a place to rest.”
Awesome says it all.
