The nematode Caenorhabditis elegans is an important experimental organism, used in the research on the effects of aging, disease, and drug development. Its small size makes it easy to manipulate and maintain in the laboratory, and it is an inexpensive and versatile model for studying human biology. A variety of genes are involved in its development, and the organism has a short lifespan of a few weeks.

Several of the worm's proteins have been shown to promote oxidative stress and decrease the lifespan of C. elegans. These studies led to the discovery of a number of underlying molecules. As a result, researchers are looking into the role of these proteins in the aging process.

Many of the genes in the nematode's genome have functional counterparts in humans. This has allowed researchers to study age-related diseases, the genetic pathways associated with aging, and the chemical interventions that prolong the lifespan of the worm. Moreover, it has facilitated the mapping of a complete neural circuitry. In fact, it was the first animal to have this completely mapped.

This model organism is also a powerful tool for investigating the development of animals and plants. Its ability to reproduce hundreds of offspring in a short period of time has made it a highly popular model organism. Furthermore, its small size and ease of maintenance make it a good choice for researchers looking to generate large numbers of samples. Also, its high fertility rates and ease of mutagenesis has made it a powerful tool for researchers interested in studying the genetics of aging.

The worm has a simple cellular structure that makes it easy to study. Its gut and sexual organs, for example, can be easily manipulated, and its reproductive cycle can be observed at room temperature. Other features that can be observed include the presence of a pharynx, skin, and four main epidermal cords. Interestingly, the worm's gut granules are able to emit blue fluorescence when exposed to ultraviolet light.

Another advantage of using this worm is its ability to be used as a high throughput screening platform. Researchers can easily generate large numbers of specimens and use them to test for different compounds that can increase the lifespan of the worm. This allows researchers to conduct chemical intervention on aging at low costs.

Its complete genome sequence has allowed scientists to map the genes that are involved in the development of the worm, and the community that has formed around this worm has accumulated a great deal of scientific data. This data has been stored and published on publicly available databases, which have facilitated the study of specific behaviors. For instance, one such database is the Worm Breeder's Gazette, a semi-annual newsletter for the nematode research community.

One of the most significant developments in C. elegans research in the last few decades has been the invention of microfluidics biochips, which allow for precise developmental assays and manipulation. Using this technology, researchers have mapped the developmental fate of every somatic cell in an adult hermaphrodite. Moreover, they have developed long-lived mutants that are resistant to oxidative stress.
