A genetically modified organism (GMO) is an organism whose genetic material has been altered using recombinant DNA [[genetic engineering]] techniques.  In most cases, genes are cut using the [[escherichia coli]] bacteria.  Other gene sequences are then inserted into the gap created, and the gene parts are reconnected.

The '''Fisher Space Pen''' is a writing implement designed specifically for use in zero-gravity environments with variable atmospheric pressure. It is a gas-charged ball-point pen with replaceable ink cartridges.

Before this pen was developed, there were some issues with fine writing.  Traditional pens depended somewhat on gravity, and even though ballpoint pens were self-contained, the ball could run dry while writing.  Extreme temperatures, and even wet surfaces were also concerns.  Pencils were the obvious choice, therefore, since they are durable, reliable and cheap.  However, those didn't come without issue either. The graphite tip could break off, but even more problematic was the dust released into the air while writing.  Without the affects of gravity, dust and debris poses a real threat to on-board equipment.  Therefore, felt-tipped markers were safer often considered a better option.

During the early days of NASA's space missions, Paul C. Fisher of the Fisher Pen Co set about developing a better pen, which could deal with the known problems of writing in space.
