A GALAXY HAS BEEN OPTICALLY SIGHTED at the same apparent location as a gamma ray burst object. In February the new orbiting telescope BeppoSAX spotted one of the mysterious gamma bursts that have baffled astronomers; do the bursts originate in our own galaxy or much further away? But quick follow-up measurements by optical telescopes located a galaxy at what seems to be the same position. BeppoSAX expects to find one burst a month, so future searches at optical wavelengths may settle the issue of whether some bursts are extragalactic. ( Science News, 22 March 1997.) TENTH ANNIVERSARY OF THE WOODSTOCK OF PHYSICS. High-temperature superconductivity (HTSC) became famous at a late-night session at the March 1987 APS meeting. Paul Grant of the Electric Power Research Institute reviews the matter a decade along.First, HTSC wire is manufactured now in km lengths and should be ready to carry industrial electric power on a test basis within two years, Grant believes. Thin films of HTSC materials are used in SQUID detectors and communications devices. No HTSC theory has yet emerged victorious, and HTSC supercurrents may be both s-wave and d- wave in nature. Government spending on research is currently $150 million per year in the U.S. and $200 million in Japan. The highest confirmed transition temperature seen so far, 164 K, occurs in a Hg-based material under pressure. (Nature, 13 March 1997.)
