List of Star Trek Starfleet starships ordered by class

This is a list of the fictional Star Trek universe's Starfleet ships organized by ship class. These vessels appear or are mentioned in the original series Star Trek (TOS), Star Trek: The Next Generation (TNG), Star Trek: Deep Space Nine (DS9), Star Trek: Voyager (VOY), Star Trek: Enterprise (ENT), the Star Trek films, or the Star Trek games. Many of the ship names, classes, or registry numbers are not identified on screen and instead are derived from The Star Trek Encyclopedia. This listing does not include ships mentioned in fan fiction related to Star Trek.

Starships

Akira class

Ambassador class

Andromeda class

Named for Greek mythological figure and nearby Andromeda galaxy.

Antares class

Named for star Antares.

Apollo class

Named for the ancient Greek solar deity and the American Apollo program (NASA).

Bradbury class

Name honors science fiction author Ray Bradbury.

Centaur class

Challenger class

Presumably named after the famed British sailing ship or the ill fated NASA space shuttle.

LSm

In molecular biology, LSm proteins are a family of RNA-binding proteins found in virtually every cellular organism. LSm is a contraction of 'like Sm', because the first identified members of the LSm protein family were the Sm proteins. LSm proteins are defined by a characteristic three-dimensional structure and their assembly into rings of six or seven individual LSm protein molecules, and play a large number of various roles in mRNA processing and regulation.

The Sm proteins were first discovered as antigens targeted by so-called Anti-Sm antibodies in a patient with a form of Systemic lupus erythematosus (SLE), a debilitating autoimmune disease. They were named Sm proteins in honor of Stephanie Smith, a patient who suffered from SLE. Other proteins with very similar structures were subsequently discovered and named LSm proteins. New members of the LSm protein family continue to be identified and reported.

Proteins with similar structures are grouped into a hierarchy of protein families, superfamilies, and folds. The LSm protein structure is an example of a small beta sheet folded into a short barrel. Individual LSm proteins assemble into a six or seven member doughnut ring (more properly termed a torus), which usually binds to a small RNA molecule to form a ribonucleoprotein complex. The LSm torus assists the RNA molecule to assume and maintain its proper three-dimensional structure. Depending on which LSm proteins and RNA molecule are involved, this ribonucleoprotein complex facilitates a wide variety of RNA processing including degradation, editing, splicing, and regulation.

Mexican Sign Language

Mexican Sign Language (“lengua de señas mexicana” or LSM, also known by several other names), is the language of the Deaf community in the urban regions of Mexico. It is the primary language of 87,000 to 100,000 people (1986 T. C. Smith-Stark).

Geographic distribution and variation

Core signing populations are found in Mexico City, Guadalajara and Monterrey, with a number of smaller cities containing signing communities. Some regional variation is found (80%-90% lexical similarity across the country according to Faurot et al. 2001).

Variation is high between age group and people of completely different religious backgrounds.

Relationship of LSM to Spanish

LSM is quite distinct from Spanish, with completely different verb inflections, different discourse structure and preferences for word order, and little use of the verb to be. However, there is extensive use of initialised signs with one study finding 37% of a 100-word list are initialised, compared to 14% for American Sign Language (Faurot et al. 2001). The same authors suggest that the Deaf community's comprehension of the Spanish language is very low.
