Charles Darwin quotation

Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science

Jean-Baptiste Colbert quotation

L'art de l'imposition consiste à plumer l'oie pour obtenir le plus possible de plumes avec le moins possible de cris

Somebody quotation

El miedo es la via perfecta hacia el lado oscuro. El miedo lleva a Windows, Windows a la desesperacion, esta al odio hacia Bill Gates y ese odio lleva a LINUX

We report the design, synthesis, and assembly of the 1.08-Mbp Mycoplasma mycoides JCVI-syn1.0 genome starting from digitized genome sequence information and its transplantation into a Mycoplasma capricolum recipient cell to create new Mycoplasma mycoides cells that are controlled only by the synthetic chromosome. The only DNA in the cells is the designed synthetic DNA sequence, including "watermark" sequences and other designed gene deletions and polymorphisms, and mutations acquired during the building process. The new cells have expected phenotypic properties and are capable of continuous self-replication.
