Windows Media Center

Windows Media Center is an application with a 10-foot user interface designed to serve as a home-entertainment hub for the living-room TV. Windows XP Media Center Edition, premium editions of Windows Vista (Vista Home Premium and Vista Ultimate) and Windows 7 (all editions, except Starter and Home Basic) comprise it. The Media Center is controlled by special remote controls or remotes. At the same time it can be operated with a mouse and/or a keyboard, too. The Media Center plays the computer user’s pictures, videos, and music from local hard drives, optical drives, and network locations. All this is then categorized by name, date, tags, and other file attributes.

Media managed through the Media Center can also be relayed via a home network to standard TV sets via the specially designed Windows Media Center Extender or the Xbox 360. This allows to use the Media Center and its features (such as view photos, videos, listen to music, watch live television, watch recorded TV, etc.) on the television set or other display device.

The advantage with these devices is that the household’s primary computer (hosting the Media Center) can be physically set up in a location more appropriate for its role, instead of being in the living room. Furthermore, the Media Center with an Extender can be accessed at the same time by several users. The Xbox 360 gaming console is a very popular example of a Media Center Extender. By the way, Xbox 360 is the only device that can work as an extender with both Windows XP Media Center as well as Windows Vista Media Center.

Windows 7 Media Center comprises all prosperous characteristics of its forerunners and brings new possibilities. Thus the performance improvement on Extenders is immediately apparent especially with the play functions like fast forward, rewind, and skip. The menus are also more manageable. The other big improvement concerns EPG (Electronic program guide), which makes utilities like Guide Tool possible. The Guide Tool is a Windows Media Center guide management application, which apart from other things enables local and remote guide management and other funny functions (see Guide Tool).

The new guide is visually better, it includes images throughout, as well as provides new ways to navigate. Moreover, all the tuners can be combined per channel to help resolve conflicts and give you control over which tuners are used for which channels. Additionally, new APIs (Application programming interface) are available there which permits to inject logos for each channel and create utilities to edit the line-up. Further, it offers the best of all around DVR (Digital video recorder) solution available today. It is even possible to import custom data, but regrettably you can´t easily backup them. At the same time it is actually extremely stable. (See for more details Windows 7 Media Center review ).

The Windows 7 Media Center undoubtedly exceeds the Vista Media Center. Microsoft has again raised the bar and has manufactured something which moves everybody beyond, even if the competition is still exists. Nevertheless, unluckily this Center isn’t for everyone. The upfront cost with the potential maintenance expenses is the most outstanding barrier to overcome.

For all that, the extant experience with Microsoft products make us believe that prices will come down and common people will afford to have Windows 7 Media Center.

Story of cloning

Composed by P. B                    

We study English discussing actual professional problems

Scientists and researchers have been working on cloning for above 100 years only. Below the short history of cloning is depicted.

1894     The first interesting research – Hans Dreisch isolated blastomeres from 2- and 4-celled sea urchin embryos and observed their development into small larvae.

At the beginning of the 20th century the German embryologist Hans Spemann was the leader in the field of the investigation:

• 1901 Spemann split a 2-celled newt embryo into two parts, resulting in the development of two complete larvae;
• 1902 Spemann split a 2-celled salamander embryo and each cell grew up on an adult, providing proof that early embryo cells carry necessary genetic information;
• 1914 and 1928 Spemann conducted an early nuclear transfer experiment (the second one was successful);
• 1938 Spemann published the results of his 1928 primitive nuclear transfer experiments involving salamander embryos in the book “Embryonic Development and Induction”.

1950     First successful freezing of a bull semen at -79°C for later insemination of cows was accomplished.

1952     First animal cloning: Robert Briggs and Thomas J. King cloned northern leopard frogs in the Institute for Cancer Research in Philadelphia.

1970     Howard Temin and David Baltimore from the National Cancer Institute (NCI), USA independently of each other isolated the first restriction enzyme. This capability led to the future manipulation of DNA.

1973     Stanley Cohen and Herbert Boyer of the University of California at San Francisco created the first recombinant DNA organism using recombinant DNA techniques.

1977     Karl Illmensee and Peter Hoppe at Jackson Laboratory in Maine, USA created mice having had only a single parent.

1978     A well respected science fiction writer David Rorvik published the novel “In His Image: The Cloning of a Man”. It was about a millionaire who had let him clone.

1979     Karl Illmensee at Jackson Laboratory in Maine, USA claimed to have cloned three mice.

1983     The first human mother-to-mother embryo transfer was completed. This procedure was performed at the Harbor Medical Center of University of California at Los Angeles (UCLA).

1984     Steen Willadsen in the Royal Veterinary College of Copenhagen cloned a sheep from embryo cells, the first verified example of mammal cloning based on nuclear transfer.

1986     Steen Willadsen in the Royal Veterinary College of Copenhagen cloned a cow.

1993     Human embryos were first cloned by a team at Newcastle University.

1996     Dolly, the sheep, the first organism cloned from adult cells was born. Ian Wilmut and Keith Campbell at the Roslin Institute in Scotland created the world first ever cloned mammal. They announced the birth in the following year, on February 23, 1997, and the worlds press beat a path to their door since then.

1997     President Clinton in the USA proposed legislation to ban the cloning of humans for 5 years.

1997     Thousands of biologists and physicians signed the voluntary five-year moratorium on human cloning in the United States.

1997     Richard Seed intended to clone a human before federal laws could effectively prohibit the process.

1998     19 European countries signed a ban on human cloning.

1998     Ryuzo Yanagimachi, Toni Perry, and Teruhiko Wakayama from the University Hawai announced that they had cloned 50 mice from adult cells since October, 1997.

During the last decade many animals (mammals) were cloned:

2000     Researchers working together in Japan and New York reported that they had cloned a pig named Xena;

2001     The first cloned cat in the United States (name Little Nicky);

2003     The Utah State University research team is the first worldwide to clone a member of the horse family, a mule;

2004     Researchers in Japan announced that a bull was cloned from a previously cloned bull – serial cloning;

2009     Camels joined the list of cloned mammals – in Dubai.

Despite a success rate in most experiments makes less than 5 percent, I think the progress is very fast and every year the result will be better and better.
