A physicist at the University of Maryland, Richard L. Greene, developed a type of microscope that utilizes superconducting wire that is supersensitive to magnetic fields. Known to physicists as Superconducting Quantum Interference Devices, the superconducting filaments in the microscope zero in on magnetic fields with great accuracy when passed over an object. The technology has medical, military, and industrial applications. (The Sun, Oct. 26/92)
