Riboviroxicnucleic Acid

Naturally occuring. Like DNA, except the number of riboviroxicnucleic acid structures increase as the biological organism ages. In other words, without these structures, we wouldn't be able to "grow up."

  • TNG: Rascals - Beverly noticed that several riboviroxicnucleic acid structures were missing in Picard, Ro, Guinan, and Keiko. Their original structures were taken from past physical exams and loaded into the Transporter Buffer to allow the four to regain their "adult" age.

  • TNG: Who Watches the Watchers - The Enterprises sensor were unable to locate Palmer, one of the scientists that was assigned to the Mintaka III duckblind. As a result of his falling out of the duckblind due to an explosion, he could not be found. Data speculated this could be due to thalium compound in the surrounding rock face.


Naturally occuring. Radioactive isotope by-product from the decay of thorium. Thorium is also known as radon-220.

  • DS9: If Wishes Were Horses - Elevated thoron emissions accompanied the appearance of aliens in the Denorios Belt.

The ultra-violet radiation that they produced was found to be sufficient only after Spock was blinded by the full spectrum radiation that McCoy was testing. Of course, Vulcans have an extra set of eyelids.

Trinimbic Turbulence

Naturally occuring. An atmospheric phenomenon. Disruptive to transporter technology, Federation targeting systems and apparently too "turbulent" for a shuttle. In real life, -nimbus is a meteorological suffix indicating that a cloud produces rain.

  • Voyager: The '37s - Prevents beaming to site of in-stasis humans; prevents use of shuttles, so Janeway decides to land Voyager instead. Prevents Voyager from assisting in a small-arms battle by interfering with the targeting systems.

  • TOS: Obsession - Kirk, Spock, and a security team (most of which ends up dead, natch) find a large deposit of it. Spock phasers off a sample, since it is too hard to cut with tools.


Naturally occuring. A radioactive isotope of hydrogen with atoms of three times the mass of ordinary light hydrogen atoms

  • TOS: Operation -- Annihilate! - (See trimagnesite.)
  • DS9: Q-Less - Used by Dax and O'Brien to trace the origins of the gravimetric disturbances.

  • Movie: The Undiscovered Country - Spock places a veridium patch on Kirk's shoulder so the Enterprise can find them upon emergence from the magnetic shield.


Artificially generated by aliens. Somehow damaging to sub-space equipment (not the same as 'vertion')

  • TNG: Force of Nature - A generator of these, disguised as a buoy, is used by environmentalists to incapacitate several ships, including the Enterprise.
  • DS9: Playing God - Threatened to destroy the proto-universe.
  • Voyager: Eye of the Needle - Captain Janeway pointed out that there were "...verteron emanations, tunneling secondary particles. It certainly looks like a wormhole..."
  • DS9: In The Hands of the Prophets - Keiko was explaining to her class at the beginning of the episode that this is what the Bajoran wormhole is made out of before Vedek Winn came in to complain about the absence of "creationist" theory in the classroom.

Victurium Alloy

Artificially generated by crew. A very dense metal alloy.

  • TNG: Hero Worship - Large amounts of it blocked the transporter.


Naturally occuring.

Warp Shell

Artificially generated by crew. A field generated by the Enterprise's engines to induce warp travel.

  • TNG: All Good Things - Picard used static warp shells to seal the temporal rifts in the three time instances.


Naturally occuring. A subspace bridge or tunnel between two points in "normal" time and space. Most wormholes are extremely unstable and their end points fluctuate widely across time and space. An improperly balanced warp drive system can create an artificial wormhole that can pose a serious danger to the ship and its crew.

  • DS9 - The only known stable wormhole, leading to the Gamma Quadrant, is right next to the station, lending DS9 its strategic importance to the Federation.
  • TNG: The Price - The Enterprise-D encountered one and their mission was to study it.
  • Movie: The Motion Picture - The Enterprise gets caught in a wormhole due to an warp engine imbalance.

Yominium Sulfide

Origin unknown. The name is derived from "Nimoy" spelled backwards.

  • Movie: The Voyage Home - Spock recalls the chemical formula for yominium sulfide [K4Ym3(SO73Es2)] during a memory test during his re-education of Vulcan. The formula is inconsistent with that of a sulfide.

Z Particle

Artificially generated by aliens; also a real type of particle. Can mess up sensor and/or visual records. In real life: today's understanding puts particles into two basic categories, matter and exchange particles. Exchange particles are thrown kind of like Frisbees between matter particles as the generators of the forces. Photons mediate the electromagnetic force, gluons mediate the strong force, the graviton is proposed (not observed) to mediate the gravitational force. The weak force is mediated by the W+, W-, and Z0 particles.

  • TNG: Devil's Due - Scientist on Ventax II station detected Z-particles coming from Ardra's ship.
  • TNG: Identity Crisis - LaForge initiated a scan for "Z-Particle emissions" on the video recording of the Tarchannen III mission.


Naturally occuring. A raw mineral from which a potent compound is derived by the Federation for use in stopping botanical plagues.

  • TOS: Cloud Minders - Zenite in its naturally found state causes temporary mental impairment when its dust is breathed. Such an effect had profound social implications in separating the Troglite miners from the Stratus city dwellers, an issue which the crew of the Enterprise had to deal with.
