    CLONING
    January 20, 1998 - United States

    American researchers announced they have cloned calves that may produce medicinal milk. Dr James Robl at the University of Massachusetts and Dr Steven Stice of Advanced Cell Technology were the first to clone cows from fetal cells in which human genes were spliced into cattle DNA. Creating two identical, genetically engineered calves are a step towards the mass production of human drugs in animals. Their goal was to turn cows into drug factories, mass producing milk that contains human proteins important for treating human diseases. The scientists used a variation on the techniques previously used in Edinburgh, Scotland, to create the cloned sheep Dolly. Cows would be better producers of the proteins than sheep because they make more milk.

    MOVIE
    January 20, 1929 - United States

    The first full-length motion picture in the U.S. filmed outdoors was released by Fox Film Corporation. Re-titled as In Old Arizona, it was adapted from a short story by O. Henry, “The Caballero's Way.” The black and white Western was a box-office hit, starring Oscar-winning Warren Baxter as “The Cisco Kid,” a carefree Mexican bandit who outwits the sheriff trying to capture him. A review in the New York Times referred to “the novelty of the Movietone,” listed various incidental sounds and particularly noted the welcome new consideration that the sound of galloping grew fainter and fainter in the distance. Film locations included Zion National Park, Bryce Canyon, the Mojave Desert in California and San Juan Capistrano mission.

ARTICLE INFORMATION :

A good placement in the web directory maximizes the chance of visibility your site.

ARTICLE CONTENT :

Search engine is the term with which we are accustomed with very much. But the web directory is not that same. The web directories are older than search engines according to the time of their invention. There are some similarities and some differences between search engines and web directories. Web directories were present before the invention of search engine. The popularity of web directories were also came before the search engines. Web directories are nothing but a directory form where different types of resources and information are gathered by human hand.

The resources are here various kinds of link which are arranged according to their names. It can be arranged alphabetically, name wise and differently. It is exactly like a directory setting where various collections of links to various site are collected or arranged maintaining some attributes and qualities. Web directories offer a search but it is not like the search of a search engine. If the search directories do not offer the search facility of some kind then it would be completely impossible to browse thousands of pages for computers. But it can not be a search engine in two ways.

Fundamentally most web directories are different from search engines as directories are edited by humans and URLs here are not collected by spiders but they are submitted by the site owners. The main advantage of Web directories is that no matter how clever spiders become, when there is a human to view and check the pages, there is a lesser chance that pages will be classified in the wrong categories. And the disadvantage with this difference is that the lists in web directories are sometime outdated because if there is no human being to edit and submit the directories then it will be outdated. You have to edit and check the submission unless it will be not working. But this is not that bad because search engines also deliver pages that do not exist anymore. And the other disadvantage with it is that sometimes you might have to wait half a year before being included in a search directory. Mainly these differences are occurred because it is not automatically maintained or mechanically maintained.

On the other hand the search engines are automatically maintained with out any help of human hand. As in web directories there is no hand of spiders that is why anyone should go there and submit the URLs to the search directories. The job of search engines is much easy and automatic but the job of web directories is not automatic but manually done. Once you are included in a particular directory, in most cases you can stay there as long as you wish to and wait for people and search engines to find you. The fact that a link to your site appears in a respectable Web directory is good because first, it is a backlink and second, you increase your visibility for spiders, which in turn raises your chance to be indexed by them.
