It would be ideal if anthropology students had access to the world's oldest artifacts for their studies. But many of those objects are locked away in museums and private collections. That's why Northern Arizona University professor Francis Smiley makes epoxy replicas of knives, blades and spear points, so his students have hands-on training with Stone Age tools.

Rollie-polies, book lice and bugs called springtails are among the 10 newly discovered insects that live only on the remote Easter Island in the Pacific Ocean. Northern Arizona University Ecologist Jut Wynne and his colleagues found eight of these creatures. They're eking out an existence in the limited entrances and skylights of caves.
