    ANIMAL-TO-HUMAN HEART TRANSPLANT
    January 23, 1964 - University of Mississippi, U.S.A.

    The first animal to human heart transplant was made. Dr. James Hardy at the University of Mississippi transplanted the heart of a chimpanzee (named Bino) into the chest of Boyd Rush (age 68) in a last-ditch effort to save the man's life because no human was heart available. The newly-transplanted heart beat on its own; but it was too small to maintain independent circulation and Rush died after 90 minutes. Hardy had to endure some severe criticism. (This was three years before Christiaan Barnard performed the first successful human heart transplant). Hardy also made the first human lung transplant in 1963 and a double-lung transplant that left the heart in place in 1987.

    FIRST EXTINCT-ANIMAL CLONE
    January 23, 2009 - Aragon, Spain

    The birth and 7-minute life of the first extinct-animal clone was described in the journal Theriogenology. A clone of the Pyranean ibex, or bucardo, was created using DNA from frozen skin samples taken in 1999 from the last individual before it died (6 Jan 2000). The mother was a closely-related subspecies of the Spanish ibex. The surrogate goat was implanted with an egg into which the bucardo's DNA had been inserted to replace the original genetic material. The research effort was the work of a team of scientists at the Center for Agro-Nutrition Research and Technology in Aragon, Spain. The team had implanted 208 embryos in different goats, of which seven became pregnant. Of those, just one resulted in a live birth, a clone that died within 7 minutes of respiratory failure due to lung defects. The bucardo thus went extinct a second time.

A wedding ring is the partner of your lifetime, therefore you should always choose your wedding ring according to your taste, and it should be such so that you can wear it all the time for your whole life. The custom of the exchange of the ring is a traditional one. According to the historians this custom of the exchange of the wedding rings during the time of wedding dates back to the ancient Egyptian civilization. The custom which started in the deserts of Africa gradually spread throughout the world and in the present day context in almost every country and in almost all the cultures this is a common custom that the bride and the groom exchange their wedding ring at the time of their wedding.

As the tradition came across the ages there came several changes in the tradition. But still the basic concept remains the same. It is believed that with the exchange of the wedding ring the souls of the couple are united with each other. Therefore, the wedding is considered as the event of the union of the two souls. However, there are several myths and beliefs associated with the custom of the exchange of the wedding rings.

One of such belief regarding the custom of the wedding ring is that it is believed that the wedding ring should be worn on the fourth finger of the left hand. And even a logic is presented in the support of this belief. It is believed that there is a nerve on that very finger which grows from the left hand ring finger and goes straight to the heart and therefore wearing the wedding ring on that very finger means keeping your beloved closest to your heart.

However, this is logic does not have any factual base as according to the medical science and the scientific view point there is no existence of any such vein and therefore the belief is also baseless. But that does not stop men from wearing the ring on the ring finger of the left hand. There is rather a different logic which can be presented in this respect. And the logic is that it is better to wear the ring on the left hand ring finger as the this is the finger of our both hands which is the least used.

And therefore wearing the wedding ring on that finger means that the ring would be much safer there. There is less chance of the ring or the precious stone in it getting damaged. Thus most of the people prefer to wear their wedding ring on the fourth finger of the left hand. This is a better idea of keeping the ring is safer condition.

There are several materials by which the wedding ring can be made. As in the most common cases the gold is the most favored choice for the metal for the wedding ring but other than that there are other metals also like platinum and titanium. Even the white gold rings are quite favorite these days.
