Scientific research is an undertaking that requires a healthy dose of dedication. From the late nights in the lab to an inspired twist to a particular experiment, it could be argued that there is a bit of us in every scientific advance we make.

This is especially true when a new phenomenon, molecule, or species is discovered, earning us the privilege of naming it. While some discoveries are named in honour of the scientists themselves, like the “Hawking radiation” or the process of “pasteurization”, others draw their names from other sources of inspiration. Whether they allude to literary references or reference pop-music giants, these names are often memorable and show us a more personal side to the scientists who chose them. Here are 10 of the Offspring’s favourite names in science and the stories behind them.

1. Bug

Field: Computer Science

Today, the term “computer bugs” commonly refer to glitches or unexpected anomalies in programming. However, the term was inspired by an actual bug! In 1964, American computer scientist and U.S. Navy rear admiral Grace Hopper was working at the Harvard Computation Laboratory when her team found a trapped moth to be the cause of errors in the Harvard Mark II computer. The moth was removed and appended into their log book.

2. Cloche

Field: Developmental biology

Organism: Danio rerio (zebrafish)

This zebrafish gene was named after the word “cloche”, French for “bell”. The name was inspired by the bell-shaped hearts of zebrafish mutants that lacked this gene. The cloche gene directs the timing and onset of a developmental program responsible for blood and blood vessel formation. The gene is highly conserved in nature, having been found in birds and humans. Scientists studying cloche believe that, given the gene’s role in development, the human version may represent an opportunity for new applications in personalized stem cell therapies.

3. Gaga

Field: Taxonomy

In 2012, a genus of ferns have been named Gaga after the famous pop-star Lady Gaga. At one stage of its life, the new genus has somewhat fluid definitions of gender and bears a striking resemblance to one of Gaga's famous costumes that she wore during the 52nd Annual Grammy Awards. Furthermore, members of the new genus also bear a distinct DNA sequence spelling GAGA.

4. Pikachurin

Field: Neurobiology

In 2008, a research group in Japan described a new extracellular matrix-like retinal protein that was thereafter referred to as Pikachurin. The protein increases the transmission speed of visual information from the eye to the brain. In fact, this function inspired the name Pikachurin, which references Pikachu, a species of the Pokémon franchise known for his lightning-fast moves and shocking electric effects.

5. Quark

Field: Particle physics

In particle physics, quarks are elementary particles of matter and constituents of hadrons (protons and neutrons being the most stable). They were named inadvertently after the German term for a kind of cream cheese by Murray Gell-Mann, who took the name from the line in James Joyce’s Finnegans Wake:

“Three quarks for Muster Mark!
Sure he has not got much of a bark
And sure any he has it’s all beside the mark.”

Gell-Mann recalls in his book The Quark and the Jaguar: Adventures in the Simple and the Complex actually having the pronunciation “kwork” for the particle before coming across James Joyce’s work. He thought “quark” was fitting due to the way they are found in nature. Funny enough, the term “quark” can also mean “nonsense” or “rubbish” in German. The six types of quarks, with equally amusing and non-scientific names, are up, down, charm, strange, top and bottom.

6. Scaptia beyonceae

Field: Taxonomy

The American recording artist and actress Beyoncé was an inspiration for naming a species of horse fly found in northeast Queensland, Australia. Interestingly, the horse fly has a dense patch of golden hairs forming a golden patch on its abdomen that reminded the scientists of the famous Queen B. Coincidentally, the fly was first collected in 1981, the same year the singer was born.

7. Smaug and Glorund

Field: Developmental biology

Organism: Drosophila melanogaster (fruit fly)

A Drosophila (fruit fly) RNA-binding protein is named Smaug, after the treasure-loving dragon from JRR Tolkien’s The Hobbit. In the early fly embryo, Smaug (the protein) prevents translation of an mRNA called nanos (the Greek word for “dwarf”), much like how Smaug the dragon tried to prevent Thorin and the Company of Dwarves from reclaiming the Lonely Mountain. Ten years later, another RNA-binding protein was identified, which prevents nanos translation in the ovaries (before Smaug’s function in embryos). Continuing with the theme, this protein was named Glorund after the first dragon in Tolkien’s lore.

8. Sonic hedgehog

Field: Developmental biology

Organism: Homo sapiens (humans)

The mammalian gene and corresponding protein Sonic hedgehog was named after the SEGA video game character. It’s part of the so-called hedgehog family of signalling proteins which govern the organization and formation of the central nervous system and limbs in vertebrate embryos. The other genes/proteins in this family are Desert hedgehog and Indian hedgehog. The Drosophila version, named hedgehog, was the first one to be discovered. Whereas normal fly embryos have eight separate bands across their abdomen made up of neatly organized spikes called “denticles”, mutant embryos  lacking the hedgehog gene are covered all over with these spikes.

Field: Plant biology

Organism: Arabidopsis thaliana (thale cress)

This gene in the plant Arabidopsis thaliana is named after one of the most recognizable comic book superheroes, Superman. The SUPERMAN gene produces a protein that regulates flower development, and mutants lacking this gene develop extra stamens (the male fertilizing organ) and less pistils (the female fertilizing organ). The expression of this gene can be modified, leading to variations (epialleles) called CLARK KENT. And like Superman in the comics, expression of the SUPERMAN gene can be suppressed by the gene KRYPTONITE.

10. Swiss Cheese

Field: Neurobiology

Organism: Drosophila melanogaster (fruit fly)

Swiss Cheese is a transmembrane protein in Drosophila whose loss leads to a degeneration of neurons and glial cells, as well as increased apoptotic cell death. The name is inspired by the characteristic holes in the brains of adult flies that lack this protein. It regulates the process of glial wrapping in adult brain development, such that mutants show hyperwrapping of glial cells and increased apoptosis of neuronal cells. The vertebrate version of Swiss Cheese, also required for glial integrity and neuronal survival, is called Neuropathy Target Esterase - a rather ordinary name compared to its Drosophila counterpart.
