| STUDY OF FOSSILS FOUND IN ARCTIC SHOWS PLANTS MORE DEVELOPED AT EARLIER TIME |
| Along with Canadian colleagues, a University of North Carolina at Chapel Hill scientist has discovered fossils of plants dating back some 420 million years. |

| UNDERGRAD FINDS CLUES TO 400- MILLION-YEAR-OLD MYSTERY |
| Steven Porter, a Johns Hopkins University senior from Cherry Hill, N.J., has conducted original research that adds new and potentially decisive evidence to a debate about the identity of one of the first organisms to make the epochal leap from the sea to dry land approximately 400 million years ago. |

| THE GENETICS BEHIND MINIATURE PLANTS |
| How do organisms maintain their size and shape despite varying environmental conditions? Unlike animals, plants are sessile and cannot maintain their internal body temperatures during ambient temperature changes. Thus, plants have evolved complex genetic pathways to maintain normal growth patterns during temperature changes. |
