Genetic EngineeringThe Basics:
In 1953 Watson and Crick illuminated the structure of DNA—the coded instructions for protein manufacture and crux of all living things. Since then enormous strides in genetic engineering research have enabled breakthroughs including the manipulation of bacteria DNA for the economical production of insulin, the engineering of the ultra-intelligent mind and the therapeutic engineering of cancer-fighting cells for melanoma patients. Current genetic engineering research serves to manipulate an organism’s genetic code in one of several ways: the damaging, or “knocking out” of genes, the augmentation or enhancement of certain genes, or the transference of genes from one organism to another. Once an alteration in a gene takes place, changes in protein production result. Scrupulous observations of these protein modifications and the subsequent physiological manifestations illuminate the precise function of the gene and implications of its removal, enhancement, or transferal. This process of gene identification, manipulation, and calculated observation greatly enhances our knowledge of the fundamental aspects of biological life. Genetic engineering will proceed with great advances in the future due to the enormous potential for altering the blueprints of biological life. With an understanding of our genetic makeup and the corresponding complex of proteins, genetic alteration offers the promise of fundamental improvement and advancement of the human condition. The Procedures:Specific enzymes serve as the genetic engineer’s tools. Restriction enzymes identify nucleotide sequences and cut DNA at specific sites while ligases rejoin portions of DNA. With these tools an engineer may add copies of a gene to a DNA strand, delete a gene, or transfer a gene from the DNA of one organism to another. The introduction of engineered DNA to a novel organism or gene therapy patient requires either the removal of the cells, introduction of new DNA, propogation, and reintroduction of cells with newly engineered DNA (a process that can prove extremely painful when applied to bone marrow transplants), or the employment of a virus. Retroviruses have been synthetically created to infect target cells with the genetically modified DNA without actually making the patient ill. Alternatively viruses similar to the common cold can achieve swifter results compared to retroviruses but lack the latter’s long-lasting effect and benignity. Relation to Terasem:Like nanotechnology, genetic engineering will prove immensely powerful in shaping the global society of tomorrow. As Terasem aims to provide a foundation for the geoethical pursuit and application of cyberconsciousness and related technologies, genetic engineering—and specifically genetic engineering that aims at enhancing human intellectual magnitude and longevity—will become increasingly integrated into our research and development projects.

A stem cell’s abilities to both divide abundantly while maintaining an undifferentiated state and differentiate into (in the case of embryonic stem cells) any cell in the body, make it an extremely valuable candidate for use in the treatment of myriad diseases. embryonic stem cells can differentiate into any type of human cell Provided a reliable source of stem cells becomes available and research less hindered by political maneuverings, improved techniques for the controlled differentiation, transplantation, and engraftment could facilitate the cell-based therapies for any disease that could be mitigated with a fresh supply of a specific type of cell. Currently stem cell therapies are used to treat leukemia, lymphoma, and blood disorders.
The Procedures:Human embryonic stem cells are derived from an embryo of approximate 4-5 days old. Give the proper conditions, they may be grown in the lab without induction of differentiation. Currently there are no human trials of embryonic stem cells but theoretically a therapy with these pluripotent cells could succeed if stem cells meet the following conditions:Adult stem cells prove less desirable from a therapy perspective simple because their potential for differentiation is limited to a small group of cells with similar lineage. They are however, harvested with much less controversy and have been successfully transplanted in leukemia patients. Relationship to Terasem:As the fields of stem cell research and genetic engineering advance, our concept of a species is already beginning to change form (see the species problem). Odd chimeric blends of species even from different phyla are now commonplace. As science and society become more and more comfortable with its’ procedures, like surgury itself stem cell manipulation will become commonplace and may even even be used for aesthetic purposes. It is not unlikely that engineered human bodies may be grown in the future. Together with nanotechnology, these bodies may be engineered to accept the mindfiles people had stored back in 2007 at lifenaut.com!

Anti Aging ResearchThe Basics:Anti-aging research pursues methods of combating the negative effects of aging so that humans may thrive physically and mentally for as long as possible. The further possibility of slowing or even reversing aging also motivates the field of anti-aging research. In general America has a collective successful history with anti-aging. Due to numerous factors, including preventing diseases and medical and sanitation advances, Americans are living longer, healthier lives compared to 100 years ago. Anti-aging research seeks to actively maintain or accelerate this trend in efforts to extend the amount of time one can enjoy life and contribute to society. Anti-aging researches work throughout a variety of realms including, genetic engineering, stem cells, mind-uploading, and nutrition. Procedures:Studies of centenarians and twin studies reveal that much of longevity depends on aspects of lifestyle. Not surprisingly then the anti-aging movement acts as a fountainhead for a range of nutritional supplements, herbal supplements, medical supplements, and extreme diets. However, to overcome the most profound of all the restrictions on healthy longevity will require somewhat more ambitious and invasive advances in the anti-aging arena. Stem-cell research that seeks to harvest, engraft, and integrate new cells to replenish aging and malfunctioning tissue offers an immensely but still largely theoretical option for anti-aging. To combat the inherent cell lifespan and cell DNA deterioration and make a stab at the fundamental parameters of aging, genetic engineering must address the healthy functioning and longevity of DNA. Enhancement of the gene that codes for telomerase, an enzyme that attaches specific nucleotide sequences to the ends of DNA strands and accordingly adds time to the cell’s life span, serves to manipulate these parameters directly. Although complications include the undesirable development of cancers, genetic engineering aimed at increased production of telomerase shows promising results in tested organisms.
