The Chinvat Bridge (Avestan: 𐬗𐬌𐬥𐬬𐬀𐬙𐬋 𐬞𐬈𐬭𐬈𐬙𐬏𐬨 Cinvatô Peretûm, "bridge of judgement" or "beam-shaped bridge") [1] or the Bridge of the Requiter [2] in Zoroastrianism is the sifting bridge, [3] which separates the world of the living from the world of the dead. All souls must cross
Cytological markers of BFB-cycle-mediated chromosomal instability: "budding" nuclei (A, C, D) and partly fragmented nucleus with double nucleoplasmic bridge (B). [1] Breakage-fusion-bridge (BFB) cycle (also breakage-rejoining-bridge cycle) is a mechanism of chromosomal instability, discovered by Barbara McClintock in the late 1930s. [2] [3]
Brahms composed the two motets based on Biblical texts and chorales but without a liturgical occasion in mind. He first wrote O Heiland, reiß die Himmel auf as individual settings of the five stanzas of Friedrich von Spee's Advent song "O Heiland, reiß die Himmel auf", possibly in 1863/64. [2]
Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic (road bridge), a pipeline (Pipe bridge) or waterway for water transport or barge traffic. An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height.
Chromatin bridge is a mitotic occurrence that forms when telomeres of sister chromatids fuse together and fail to completely segregate into their respective daughter cells. Because this event is most prevalent during anaphase , the term anaphase bridge is often used as a substitute.
Golden Gate assembly involves digesting DNA sequences containing a type IIS restriction enzyme cut site and ligating them together. Golden Gate Cloning or Golden Gate assembly [1] is a molecular cloning method that allows a researcher to simultaneously and directionally assemble multiple DNA fragments into a single piece using Type IIS restriction enzymes and T4 DNA ligase.

The slime mold shows how intercellular communication with a small molecule (e.g., cyclic AMP) allows a simple organism to form from an organized aggregation of single cells. [3] Research into cell signalling investigated a receptor specific to each signal or multiple receptors potentially being activated by a single signal. [ 4 ]
