I read an article about three people, two American cell biologists and a German biochemist who won the 2013 prize for physiology or medicine. The Americans names were James Rothman and Randy Schekman and the German man’s name was  Thomas C. Südhof. James Rothman of Yale, Schekman of the University of California and Südhof of Standford.

The winning discovery of theirs was the discovery of vesicles. Vesicles are bubbles surrounding  membranes that transport  things from cell to cell. They carry out every day sort of processes like delivering chemicals throughout your brain when ever you think a thought. Vesicles also deliver hormones through your body. They didn’t discover this all at once they all worked towards this amazing discovery in different parts of the world.

Schekman discovered how the transportation system was organized. He did this by experimenting with the well-known genetics of yeast as a model. These experiments help lead to the discovery of three mutant genes that the cellular delivery system to break down.

Rothman discovered how the cell delivers to the correct place every time. This he was able to find by doing experiments with proteins and mammalian cells.

Südhof discovered how the cell delivers on time. He worked on experiments with nerve cell communication, his specialty. He observed that the trigger was calcium ions.

In my opinion it is surprising that even now people are discovering different parts of cells and entirely

 different cells. It gives you hope for future scientific discoveries of importance involving the human 

 body.
