Probing the geodynamo
Article Abstract:
Scientists relied primarily on simple theories to explain the geodynamo and its magnetic mysteries and have developed new ways to explore its detailed workings. Satellites are providing clear snapshots of the geomagnetic field at the Earth's surface, while new strategies for simulating Earthlike dynamos on supercomputers and creating physical models in the laboratory are orbital observations.

Probing high-temperature superconductivity
Article Abstract:
The Mar 1987 announcement of the discovery of a ceramic that superconducts at relatively high temperatures created an excitement in the scientific community that remains today. Research in the nine years since into how this material superconducts is described.

Heike Kamerlingh Onnes's discovery of superconductivity
Article Abstract:
Onnes's fascination with low-temperature research led him to discover the properties of superconductivity. Onnes's goal was to produce liquid hydrogen, and then liquid helium. He succeeded in bringing temperatures down low as 1.7 kelvins.
