Although aluminum is the most abundant metal in Earth's crust, no living organism has been known to utilize it. In fact, this ubiquitous element is often considered toxic: Aluminum-contaminated soil can dramatically reduce yields of many crops, for example.
Now, as a result of a chance encounter on a hike in Yellowstone National Park, a research group believes it has found a bacterium that requires aluminum to thrive.
Some scientists are less convinced, drawing caution from a history of unconfirmed claims of a biological role for the metal. "Skepticism is the best place to start," says microbiologist Simon D. Silver of the University of Illinois at ...
