THis Day In History (1939): First Nylon Stockings Sold
In 1939, nylon stockings went on sale in the U.S. for the first time to employees at DuPont's Wilmington, Delaware nylon factory. Nationwide sales began on 15 May 1940.
The modern materials revolution began in 1938 with DuPont's commercialization of their nylon product, which was the first man-made fibre to be made exclusively from mineral sources. “Nylons,” as they were soon called, eventually replaced silk stockings. link

Martian Meteorites Found To Contain Methane
An international team of researchers has discovered traces of methane in Martian meteorites.
The researchers examined samples from six meteorites of volcanic rock that originated on Mars. The meteorites contain gases in the same proportion and with the same isotopic composition as the Martian atmosphere. All six samples also contained methane, which was measured by crushing the rocks and running the emerging gas through a mass spectrometer. The team also examined two non-Martian meteorites, which contained lesser amounts of methane.
The discovery hints at the possibility that methane could be used as a food source by rudimentary forms of life beneath the Martian surface. On Earth, microbes do this in a range of environments.
