*1949* Archaeology

A diver spots amphoras (Greek storage jars) on the sea bottom off the tiny island of Grand Congloué a few kilometers outside the harbor at Marseilles, France. In 1952 the site is determined to be the wrecks of two ships from classical times.

Mexican archaeologist Alberto Ruz Lhuillier [b. Paris, January 27, 1906, d. Montreal, Canada, August 25, 1979] excavates the previously untouched tomb of Pacal, eighth-century ce Maya ruler of Palenque. The tomb is filled with rich jade jewelry. The body wears a dramatic jade burial mask, reminding archaeologists of that of Tutankhamen.

Astronomy
Fred Lawrence Whipple [b. Red Oak, Iowa, November 5, 1906] suggests (correctly) that comets are "dirty snowballs," consisting of ice or ammonia ice and rock dust. See also 1577 Astronomy.

William Albert Hiltner [b. 1914, d. 1991] and John Scoville Hall [b. Old Lyme, Connecticut, June 20, 1908, d. October 15, 1991] discover polarization of light by interstellar matter. See also 1819 Astronomy.

Ralph Belknap Baldwin [b. 1912] formulates his meteor theory of the lunar surface. Before Baldwin, the most common explanation of the lunar craters had been volcanism. Baldwin demonstrates convincingly that the craters have been caused by impacts and not by volcanoes. See also 1921 Astronomy.

Biology
In Die Polarisation des Himmelslichtes als orientierender Faktor bei den Tänzen der Bienen ("the polarization of sky light as a means of orientation during the bee's dances", Karl von Frisch shows that bees orient themselves during dances, which they use to communicate the location of food to other bees, by observing how sunlight is polarized by reflection. See also 1950 Biology.

Belgian cytologist Christian René de Duve [b. Thames Ditton, England, October 2, 1917] discovers signs of a cellular structure that in 1955 he names the lysosome. See also 1945 Biology; 1974 Biology.

Kenneth Stewart Cole [b. Ithaca, New York, July 10, 1900, d. April 18, 1984] and George Marmont invent the "voltage clamp" for controlling the cell membrane potential. This will become the most important tool for investigating transmission of signals from nerves. The method is based on using the clamp to adjust the electric potential of a cell part, such as the axon of a squid (used because of its large size), to a desired amount and then to use the same apparatus to change the potential. See also 1952 Biology.
