Photo detail

This Jan. 29, 2011 photo provided by Zane Moore shows doctoral student at UC Davis Moore holding an albino redwoods branch in Henry Cowell Redwoods State Park, Calif. Moore may have figured out why albino redwoods turn white in the middle of deep green California redwood forests. Scientists know that albino redwoods are genetic mutations that attach themselves to the roots and branches of normal redwood trees and live by drawing sugars off the huge host trees. Moore, has analyzed the needles of the redwood leaves in a lab and found that they contain high levels of the toxic heavy metals nickel, copper and cadmium. (Steve Moore/Zane Moore via AP)
