On the Cover

Photographs of a phase transition in a new class of liquid crystals (tetrapode oligomers). The right column shows a uniaxial nematic phase in a free-standing film; as the temperature is lowered, a new biaxial nematic phase is observed (left column). The transition is accompanied by a change in the texture (top images) and by a splitting of the isogyres (bottom).
