An egg-shaped fullerene, or "buckyball egg" has been made and characterized by chemists at UC Davis, Virginia Tech and Emory and Henry College, Va. The unexpected discovery opens new possibilities for structures for fullerenes, which could have a wide range of uses.

The experiment was actually part of a project to find new, more predictable ways to make fullerenes, Beavers said. The researchers were trying to make fullerenes with atoms of terbium, a metal from the lanthanide series of the periodic table, trapped inside. Metals similar to terbium are used as contrast agents for some medical scanning procedures. By putting these metals inside fullerenes, the researchers hope to make compounds that could be both medically useful and well-tolerated in the body.
