The E. coli long-term evolution experiment ( LTEE) is an ongoing study in experimental evolution begun by Richard Lenski at the University of California, Irvine, carried on by Lenski and colleagues at Michigan State University, [2] and currently overseen by Jeffrey E. Barrick at the University of Texas at Austin. [3]

Escherichia coli. Escherichia coli ( E. coli) is a Gram-negative, rod-shaped, facultative anaerobic bacterium. This microorganism was first described by Theodor Escherich in 1885. Most E. coli strains harmlessly colonize the gastrointestinal tract of humans and animals as a normal flora.
In fact, the end result of E. coli morphogenesis is a cylindrical tube with hemispherical caps. It is argued that physical principles affect biological forms. In this view, genes code for products that contribute to the production of suitable structures for physical factors to act upon. After introduction of a physical model, the discussion is ...
The Beulé Gate is a fortified gate leading to the Propylaia of the Acropolis of Athens, Greece.It was constructed largely of repurposed material taken from the 4th-century BCE Choragic Monument of Nikias and integrated into the Post-Herulian Wall, a late Roman fortification built around the Acropolis in the years following the city's sack by the Germanic Heruli people in 267 or early 268 CE.
For Escherichia coli in molecular biology, see Escherichia coli (molecular biology). Escherichia coli ( / ˌɛʃəˈrɪkiə ˈkoʊlaɪ / ESH-ə-RIK-ee-ə KOH-ly; commonly abbreviated E. coli) is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
The discussion of bacterial morphology has been dominated by questions about how a cell manages to create a rod shape, which, of course, is but one example of the more general question of how a cell constructs any shape. The expectation is that by answering this (deceptively) simple question we may acquire knowledge that will point us to a ...
