Issues

Two experimental groups have detected the distinctive pitter‐patter of quasiparticles with charge e/3 tunneling across a narrow region of a fractional quantum Hall system.

Like the pea that disturbed the sleep of the fairy‐tale princess, a Josephson tunneling experiment upset the consensus favoring a d‐wave pairing of the electrons in high‐temperature superconductors. Further studies of the tunneling behavior have now resolved the discrepancy.

As the small test accelerator for the proposed 20‐km electron‐positron collider nears completion, SLAC and KEK have drafted a memorandum of understanding.

The same photoconducting materials that made photocopying possible in the 1960s are now poised to provide a basis for convenient, fully digital radiography.

Microkelvin variations in the cosmic microwave background encode a wealth of information about the origin and composition of the universe.

Though all but forgotten, the Austrian physicist Marietta Blau was a pioneer in the field of nuclear emulsions. Her life and career tragically disrupted by World War II, she maintained a lifeline to the physics community through the simple, portable technique she helped to create.
