2007 A discovery of human genome mapping and changes
The human genome is the genome of Homo sapiens, which is stored in 23 pairs of chromosomes. Given that there is a sequence the genome of the order of all DNA bases in a genome, a genome map identifies points of reference. A genome map is less detailed than the genome sequence and AIDS in the navigation of the genome. While working at the National Institute of Health, Craig Venter has discovered a technique to quickly identify all mRNA present in a cell, and began to use it to identify the genes in the human brain. The sequence short cDNA fragments discovered by this method are called expressed sequence tags. Thanks to his scientific research to the world one step closer to medicine personalized, Craig Venter was included in Time magazine in 2007 and 2008 Time 100 list of the most influential people in the world.
2007 Discovery of the di-positronium
Di-positronium is a molecule composed of two atoms of positronium. He expected to exist in 1946 by John Archibald Wheeler, and later studied in theory, but has not been observed until 2007 in an experiment of David Cassidy and Allen Mills of the University of California at Riverside.
