"We were stepping over all these dead trees on the ground that had been killed by the initial blast," Tim Mousseau, a professor of biology at the University of South Carolina, said in a statement. "Years later, these tree trunks were in pretty good shape. If a tree had fallen in my backyard, it would be sawdust in 10 years or so." [Images: Chernobyl, Frozen in Time]
Mousseau and Anders Møller of the Université Paris-Sud have made ongoing investigations into the biology of radioactive areas like Chernobyl and Fukushima, Japan.
