Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek caeno- (recent), rhabditis (rod-like) and Latin elegans (elegant). In 1900, Maupas initially named it Rhabditides elegans. Osche placed it in the subgenus Caenorhabditis in 1952, and in 1955, Dougherty raised Caenorhabditis to the status of genus.
Howard Robert Horvitz ForMemRS NAS AAA&S APS NAM is an American biologist best known for his research on the nematode worm Caenorhabditis elegans, for which he was awarded the 2002 Nobel Prize in Physiology or Medicine, together with Sydney Brenner and John E. Sulston, whose "seminal discoveries concerning the genetic regulation of organ development and programmed cell death" were "important for medical research and have shed new light on the pathogenesis of many diseases".
Sir John Edward Sulston was a British biologist and academic who won the Nobel Prize in Physiology or Medicine for his work on the cell lineage and genome of the worm Caenorhabditis elegans in 2002 with his colleagues Sydney Brenner and Robert Horvitz at the MRC Laboratory of Molecular Biology. He was a leader in human genome research and Chair of the Institute for Science, Ethics and Innovation at the University of Manchester. Sulston was in favour of science in the public interest, such as free public access of scientific information and against the patenting of genes and the privatisation of genetic technologies.
The crimson rosella is a parrot native to eastern and south eastern Australia which has been introduced to New Zealand and Norfolk Island. It is commonly found in, but not restricted to, mountain forests and gardens. The species as it now stands has subsumed two former separate species, the yellow rosella and the Adelaide rosella. Molecular studies show one of the three red-coloured races, P. e. nigrescens, is genetically more distinct.
The ring-tailed vontsira, locally still known as the ring-tailed mongoose is a euplerid in the subfamily Galidiinae, a carnivoran native to Madagascar. It is the only species in the genus Galidia.
John Graham White is an Emeritus Professor of Anatomy and Molecular Biology at the University of Wisconsin–Madison. His research interests are in the biology of the model organism Caenorhabditis elegans and laser microscopy.
In molecular biology lin-4 is a microRNA (miRNA) that was identified from a study of developmental timing in the nematode Caenorhabditis elegans. It was the first to be discovered of the miRNAs, a class of non-coding RNAs involved in gene regulation. miRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give a 21 nucleotide product. The extents of the hairpin precursors are not generally known and are estimated based on hairpin prediction. The products are thought to have regulatory roles through complete or partial complementarity to mRNA. The lin-4 gene has been found to lie within a 4.11kb intron of a separate host gene.
The elegant water shrew is a species of mammal in the subfamily Soricinae of the family Soricidae. It is the only species within the genus Nectogale. It lives in Sikkim and China.
Victor R. Ambros is an American developmental biologist who discovered the first known microRNA (miRNA). He is a professor at the University of Massachusetts Medical School in Worcester, Massachusetts.
Gary Bruce Ruvkun is an American molecular biologist at Massachusetts General Hospital and professor of genetics at Harvard Medical School in Boston. Ruvkun discovered the mechanism by which lin-4, the first microRNA (miRNA) discovered by Victor Ambros, regulates the translation of target messenger RNAs via imperfect base-pairing to those targets, and discovered the second miRNA, let-7, and that it is conserved across animal phylogeny, including in humans. These miRNA discoveries revealed a new world of RNA regulation at an unprecedented small size scale, and the mechanism of that regulation. Ruvkun also discovered many features of insulin-like signaling in the regulation of aging and metabolism. He was elected a Member of the American Philosophical Society in 2019.
Mutinus elegans, commonly known as the elegant stinkhorn, the dog stinkhorn, the headless stinkhorn, or the devil's dipstick, is a species of fungus in the Phallaceae (stinkhorn) family. A saprobic species, it is typically found growing on the ground singly or in small groups on woody debris or leaf litter, during summer and autumn in Japan, Europe, and eastern North America. The fruit body begins its development in an "egg" form, resembling somewhat a puffball partially submerged in the ground. As the fungus matures, a slender orange to pink colored stalk emerges that tapers evenly to a pointed tip. The stalk is covered with a foul-smelling slimy green spore mass on the upper third of its length. Flies and other insects feed upon the slime which contains the spores, assisting in their dispersal. Due to their repellent odor, mature specimens are not generally considered edible, although there are reports of the immature "eggs" being consumed. In the laboratory, Mutinus elegans has been shown to inhibit the growth of several microorganisms that can be pathogenic to humans.
Cunninghamella elegans is a species of fungus in the genus Cunninghamella found in soil.
mir-48 microRNA is a microRNA which is found in nematodes, in which it controls developmental timing. It acts in the heterochronic pathway, where it controls the timing of cell fate decisions in the vulva and hypodermis during larval development.
In molecular biology mir-84 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.

Mariannaea elegans an anamorphic fungus. It is mainly found on rotting wood and soil. M. elegans is not pathogenic to humans, animals, or plants.
Cytochrome P450, family 14, also known as CYP14, is a nematoda cytochrome P450 monooxygenase family. The first gene identified in this family is the CYP14A1 from the Caenorhabditis elegans. The function of most genes in this family is unknown.
