Harpactus elegans is a species of hunting wasps in the tribe Bembicini. It is found in Europe.
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 whose research on the nematode worm Caenorhabditis elegans 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 spermatheca, also called receptaculum seminis, is an organ of the female reproductive tract in insects, e.g. ants, bees, some molluscs, Oligochaeta worms and certain other invertebrates and vertebrates. Its purpose is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. Spermathecae can sometimes be the site of fertilisation when the oocytes are sufficiently developed.
The Bembicini, or sand wasps, are a large tribe of bembecid wasps, comprising 20 genera. Bembicines are predators on various groups of insects. The type of prey captured tends to be rather consistent within each genus, with flies (Diptera) being the most common type of prey taken. Nests are typically short, simple burrows, with a single enlarged chamber at the bottom which is stocked with freshly paralysed prey items for the developing wasp larva; the egg may sometimes be laid before the chamber is completely stocked. It is common for numerous females to excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations, which tend to attract various species of parasitic flies and wasps, many of which are cleptoparasites; in some cases, the sand wasps prey on their own parasites (e.g.,), a surprisingly rare phenomenon in the animal kingdom. Although sand wasps are normally yellow and black, some are black and white with bright green eyes.
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.
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 Wyoming ground squirrel is a species of rodent in the family Sciuridae. It is endemic to the Northwestern United States.
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 and Nobel Laureate who discovered the first known microRNA (miRNA). He is a professor at the University of Massachusetts Medical School. He completed both his undergraduate and doctoral studies at the Massachusetts Institute of Technology. Ambros received the Nobel Prize in Physiology or Medicine in 2024 for his research on microRNA.
Gary Bruce Ruvkun is an American molecular biologist and Nobel laureate at Massachusetts General Hospital and professor of genetics at Harvard Medical School in Boston.
The western terrestrial garter snake is a western North American species of colubrid snake. At least five subspecies are recognized.
Chaetonotus elegans is a species of gastrotrichs in the genus Chaetonotus. It is found in freshwater of Europe.
In molecular biology mir-84 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
Hypericum elegans is a species of flowering plant in the St. John's wort family Ericaceae. It is native to Europe.
Harpactus is a genus of hunting wasps in the tribe Bembicini.
