FORTRAN
September 20, 1954
September 20, 1954
The first successful test compilation and execution of a computer program using what became FORTRAN was run by Harlan Herrick at IBM. It took until 1957 to develop into a fully-operational, commercial product. As implied by its name (FORMula TRANslator), Fortran was designed as a high-level language for technical and scientific applications which primarily needed calculation, rather than working with characters. John Backus at IBM supervised the development of the programming language that would allow users to express their problems in commonly understood mathematical formulae. By 1958 the language was expanded to Fortran II, which included subroutines, functions and common blocks, and in 1962 IBM introduced the extended Fortran IV.
DNA
September 20, 1952 - U.S.A.
September 20, 1952 - U.S.A.
Alfred Hershey and Martha Chase published a report confirming DNA holds hereditary data. Their experiment used the T2 bacteriophage, which, like other viruses, is just a crystal of DNA and protein. It can reproduce when inside a bacterium such as E. coli. When the new T2 viruses are ready to leave the host E. coli cell (and go infect others), they burst the E. coli cell open, killing it (hence the name "bacteriophage"). Hershey and Chase were seeking an answer to the question, "Is it the viral DNA or viral protein coat (capsid) that is the viral genetic code material which gets injected into the E. coli?" Their results indicated that the viral DNA, not the protein, is its genetic code material.

All of us have a God in us
by Earth Day, Kenya
"...All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet. It must be this voice that is telling me to do something, and I am sure it'as the same voice that is speaking to everybody on this planet at least everybody who seems to be concerned about the fate of the world, the fate of this planet. Wangari Maathai-Noble Peace prize winner, Deputy Minister of Environment, founder Green Belt movement in Kenya...."

More vehicles
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?)
about Facts about Drugs
Facts about drugs can protect against drug abuse. Legal drugs, such as alcohol and tobacco, kill more people than illegal drugs. Tobacco (smoking cigarettes) kills more people than any other drug. Illegal drugs including heroin, cannabis, ecstasy and amphetamines can have unknown or dangerous ingredients. Mixing drugs, especially with alcohol, can be fatal.
