Mutchler, Andrew J. Steffl Buie, Marc W., William J. Merline, John Spencer R., F. Eliot Young and Leslie A. Young.
2005 Discovery of Nix
Nix is a satellite Pluto's natural. It was found, along with Hydra in June 2005 by Pluto Hubble Space Telescope to search team, composed by Hal Weaver, A., S. Alan Stern J. Max Mutchler, Andrew J. Steffl Buie, Marc W., William J. Merline, John Spencer R., F. Eliot Young and Leslie A. Young.
2007 discovery of the human genome and assignment changes
The human genome is the genome of Homo sapiens, which is stored in 23 pairs of chromosomes. Whereas the genome sequence shows the order of each DNA base in a genome, a map genome identifies benchmarks. A genome map is less detailed than the sequence of the genome and aid in navigation of the entire genome. While working at the Institute NHS, Craig Venter discovered a technique for rapid identification of all mRNA present in a cell, and began to use it to identify human brain genes. The short DNA sequence fragments discovered by this method are called expressed sequence tags. Through its research to bring the world one step closer to personalized medicine, Craig Venter was listed 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. Is expected to exist in 1946 by John Archibald Wheeler, and later studied in theory but not observed until 2007 in an experiment conducted by David Cassidy and Allen Mills of the University of California, Riverside.
