BALTIMORE & OHIO RAILROAD
February 28, 1827 - Baltimore & Ohio USA
The Baltimore & Ohio Railroad became the first U.S. railway chartered for the commercial transportation of freight and passengers. Investors hoped that a railroad would allow Baltimore, the second largest U.S. city at that time, to successfully compete with New York for western trade. New Yorkers were profiting from easy access to the Midwest via the Erie Canal.
DNA STRUCTURE DISCOVERED
February 28, 1953 - Cambridge, MA, U.S.A.
James Watson, from early on this Saturday, spent his time at the Cavendish Laboratory in Cambridge, shuffling cardboard cutout models of the molecules of the DNA bases: adenine (A), guanine (G), cytosine (C) and thymine(T). After a while, in a spark of ingenuity, he discovered their complementary pairing. He realized that A joined with T had a close resemblance to C joined with G, and that each pair could hold together with hydrogen bonds. Such pairs could also neatly fit like rungs meeting at right-angles between two anti-parallel helical sugar-phosphate backbones of DNA wound around a common axis. Such structure was consistent with the known X-ray diffraction pattern evidence. Each separated helix with its half of the pairs could form a template for reproducing the molecule. The secret of life!

about Stolen On New Year's
More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)
