Professor’s research lands on cover of ‘Nature’

William Stein, right, associate professor of biological sciences, helps place two Eospermatopteris fossils, genus of plants known from fossil stumps discovered in the 1870s near Gilboa, N.Y., at the E.W. Heier Teaching and Research Greenhouse at Science 3. Stein believes the fossils are between 370- to 380-million years old.
