stau

Stau is a term with several distinct meanings in different contexts. In German, the most common usage refers to a traffic jam, a situation in which vehicle flow on roads or highways is slowed or halted due to congestion, accidents, or bottlenecks. The word can also denote an obstruction or bottleneck more generally, and in civil engineering or hydrology it may describe a barrier such as a dam or weir that holds back water to create a reservoir or to regulate floodwaters. The concept of stau thus encompasses both everyday congestion and engineered water-control structures, depending on the context.

In biology, Stau (often written as Staufen) refers to a family of RNA-binding proteins. In Drosophila melanogaster,
