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.
The elegant crested tinamou or martineta tinamou is a medium-sized tinamou that can be found in southern Chile and Argentina in shrubland.
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 European Union itself does not issue ordinary passports, but ordinary passport booklets issued by its 28 member states share a common format. This common format features a coloured cover emblazoned—in the official language(s) of the issuing country —with the title "European Union", followed by the name(s) of the member state, its coat of arms, the word "PASSPORT", together with the biometric passport symbol at the bottom centre of the front cover.
Chonetes is an extinct genus of brachiopods. It ranged from the Late Ordovician to the Middle Jurassic.
Paxilline is a potassium channel blocker. Paxilline is a toxic, tremorgenic indole alkaloid produced by Penicillium paxilli . Paxilline was found to significantly extend the lifespan healthspan and mobility of C. elegans aged worms, but had no such effect on young worms.
