    DNA
    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.

    FORTRAN
    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.

    about Eyesight Myth and Fact

    Myth: Staring at a computer screen all day is harmful to the eyes. Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.

Many people most of the time travel. It's not a great think but when you are traveling with your pet that time you need to concentrate more on your pet which may disturb you to enjoy your vacation.

If your pet is very young or old, or is ill, pregnant, injured recovering form surgery then avoid to take them with you as is such time they need more concentration and if you really wish to carry your pet in your vacation then consult with pet sitter rather than take a chance on injuring your pet by taking it with you. If you are in doubt, ask your veterinarian. If your pet has not traveled before, try a short overnight or weekend trip first.

Before you leave inform your veterinarian where you will be traveling to, for how long, as well as whether your pet will be traveling by air or car. Ask about any flea, heartworm, or tick risks for areas you will be traveling to. If your pet becomes carsick or restless when traveling, ask veterinarian about appropriate medications or treatments.

Many times while traveling it happen we get separated from our pet and they get panic so try to avoid such type of situation for traveling safely with your pet. Your pet should wear a safety collar all the time with a tag showing proof of rabies vaccination and your name address, phone number in case your pet becomes separated from you.

To take care of your pet when away from home try to keep fresh water available and don think of changing their die all of a sudden. Make sure your pet is accustomed to the crate before you begin your trip.
