Researchers from the University of Yale have now identified a huge obstacle to convert cells back to their original youthful form. Like the speed needed by the cell cycle or the time needed by a cell to divide.

The cell fate is a one-way street that is a fundamental axiom of biology as the cell starts merging with the blood, skin or muscles it remains the same. When a Japanese scientist introduced four easy factors into skin cells and then to an embryonic state be4comes almost like any type of cell in the body.

The scientists revolutionized the discovery by the Nobel Laureate Shinya Yamanaka in the year 2012 after using a patient’s own cells. The process was slow and not efficient and hard to discover a genetic explanation of how the cell should be.

The study by Shangqin Guo explained the implications of the bottleneck in re-programming that makes it hard to produce pluripotent cells individually for each stem cell for therapy and research. Guo noted that the human diseases are merged with abnormalities in establishing correct identification of cell as well as the abnormalities in cell cycle behavior of the human body.

The challenge of drawing the major sites of the web was mapped by Slovakian designer Martin Vargic. The challenge that fascinates many virtual cartographers was accepted by amateur graphic designer Martin Vargic making the challenge appear real and unique.

The project was started in December 2013 by using old National geographic maps for the visual inspiration and Alexa data of the popular websites in the world to scale the various landmasses. The fascinating fact is that that map was drawn by hand and directly into Photoshop.

The map is divided into two different parts: The eastern continent displays the Old World that shows the gaming companies, software companies and some of the real life websites. Whereas, the western part, New World, is made up of two major continents – the northern one shows the art websites, forums, blogs, video websites search websites and social networks.

All the main adult oriented sites are situated in the south-western continent in addition to torrent sites and several warez websites. The designer said that he was highly inspired by the previous map of the internet drawn by the artist Randal Munroe. He was the programmer behind the popular xkcd web-comic.
