-Ome Sweet -Ome

We asked Evan Hepler-Smith, a historian of science whose work focuses on how chemists have used language, data, and method over the last hundred years, what the sort of questions he asks might reveal about contemporary science. He sent us the following guest post; you can find out more about his work here.

Recently, a small group of scientists has begun been laying the foundation of a new interdisciplinary field. Their ambitions include applying biological mechanisms to the synthesis of new drug candidates, integrating huge collections of biological and chemical data, and linking western pharmaceutical science with the study of traditional Chinese medicine at the molecular level. They call their new field “chemomics.”

So far, chemomics isn’t much more than a twinkle in the eye of a few pharmaceutical chemists, but it already has a catchy name, which makes one reflect on how, as Patrick McCray recently remarked, nearly everything seems to have an “-omics” these days.

In the life sciences, there’s the proteome, the microbiome, the interactome, and dozens more (not to mention the genome – more on this ur-ome in a minute). -Omes have colonized neuroscience (the connectome) and cultural studies (the culturome). Like other trends in scientific terminology and method – the “molecular” sciences, “computational” fields, neuro-everything, and the many faces of translational medicine – -omes can be easy to scoff at. But they’ve attained impressive cultural, institutional, and intellectual stature, and that makes the suffix1 worthy of historians’ attention.

The connectome: where “neuro-” meets “-omics.”(Source: http://www.nature.com/polopoly_fs/7.3435.1332258664!/image/brain.jpg_gen/derivatives/landscape_630/brain.jpg)
The scientists have certainly been paying attention. 

There are Wikipedia articles, a blog, and at least two journals dedicated to “-omics.” -Omes engage some of the most prominent themes in recent science, from Big Ideas to Big Data. In the inaugural issue of OMICS in 2002, the editor-in-chief explained that the mission of the journal was to “facilitate a forum for new voices, provide tools for networking researchers from diverse fields and industries, and act as a catalyst for innovative, perhaps even controversial positions.”2 The homepage of Nature’s now-defunct -Omics Gateway explains, with British candor, “Many of the emerging fields of large-scale data-rich biology are designated by adding the suffix ‘-omics’ onto previously used terms.”

The best-known -ome is the genome, and it seems safe to trace the explosion of -omes, beginning in the mid-90s, to the Human Genome Project. (For example, OMICS began its life as Genome Science and Technology, edited by Craig Venter.) Most of the younger -omes are the fruit of both the HGP’s successes (its totalizing vision and enthusiasm for public-private collaboration) and failures (the considerable gap between knowledge of the genome and knowledge of the organism).

-Omes also seem to share certain structural features. Let’s return to chemomics.

Chemomics, write its proponents, is the study of molecular subunits with a specific biological function. Each such subunit is a “chemoyl”; the set of all chemoyls is the “chemome.” Chemomics studies3 the chemome “using approaches from chemoinformatics, bioinformatics, synthetic chemistry, and other related disciplines.”4

On this basis, we might sketch a tentative picture of what’s in an -ome. First, the -omemaker carves up some portion of the world into a set of atom-like units (chemoyls, the “molecular interactions” that make of the interactome, the n-grams of culturomics). These units should be accessible to study using familiar methods from one or more disciplines, like chemistry and statistics. Their treatment as a significant level of organization, however, is usually something new. The -omicist reassembles these units to build up a picture of the world (proponents of the chemome hype it as a “biological periodic table”). Finally, collaborators from different disciplinary backgrounds start investigating this -omeland, usually by generating, collecting, and interpreting Big Data.

-Omes derive significant rhetorical and conceptual power from an easy slippage between the levels of the individual, the community, and the abstract ideal type. (The contributors to Keith Wailoo, Alondra Nelson, and Catherine Lee’s new volume on genetics and identity have explored some consequences of this slippage.) And they tend to make use of powerful metaphors (like the “biological periodic table”), often derived from traditional disciplines, to describe their entities and arguments.

From the genome to the microbiome, we are all -omebodies.

Interdisciplinarity is a challenging topic for historians of science used to arguments (and source bases) framed in disciplinary terms (though this hasn’t stopped Cyrus Mody, among others, from tackling it effectively). -Ome studies (-omework?) could be a productive route for advancing the study of interdisciplinarity, popularization, and Big Data in recent science. 

A careful look at chemomics, for example, could tell us something about the nexus of the multinational pharmaceutical industry, traditional therapeutics, state funding of science in China, the cultural authority of the life sciences, and the translation of computational methods and data between fields. The same could be said for better-known -omes, and for the other clusters of fashionable new fields mentioned above. At the very least, all those neologisms make tempting targets for some old-fashioned free-text-search culturomics.

[1] An etymological tangent, per the OED: the Greek -oma, a generic suffix for converting verbs into neuter nouns (e.g. diploma), made its way into English mainly in the form of Greek medical terminology, particularly swellings and tumors (carcinoma, sarcoma, lymphoma). In part through the influence of French and German forms, the variant -ome began to pop up, and got attached to the names of specific structural elements of plants or animals (rhizome, chromosome). “Biome” and “genome” were coined in the early twentieth century, and in somewhat different ways, both expanded the sense of -ome from “part” to “part-that’s-also-a-whole.”

The resemblance of –ome and –omics to the -nomy and -nomics of economics is an etymological coincidence but surely didn’t hurt the popularity of either suffix.

[3] -omics literature seems to be rife with pseudo-passive constructions like this; there are “-omes” and “-omicses” but not many “-omicists." What are the stakes of choosing a name for a practice that does or doesn’t lend itself to a name for practitioners?

  1. Nice analysis. Two comments:
    -- Do you know Josh Lederberg's essay, "'Ome Sweet 'Omics: A Genealogical Treasury of Words." The Scientist 15, no. 7 (2001)?
    -- You might historicize this further by looking at the trends in trendy science disciplinary labels, from "biology" to "molecular biology" through to the whateverome. Your essay suggests you think these are more than merely fads. I'd say, somewhat cynically, that if that's true, there is a quest for power (money, influence) behind it. Can you tease out the power relationships in the omics fad?

    1. Thanks, Nathaniel.

      I don't know the essay (I should have noticed it cited on the "Omics" wikipedia page!) - I'll certainly check it out. He's square in the middle of a number of the trends I mentioned above: apart from his advocacy of the "microbiome" concept, he was an important figure in the early stages of life sciences computing (DENDRAL), and was part of the tangled and interesting world of federally funded interdisciplinary research at Stanford. Joe November wrote about Lederberg and DENDRAL in his 2012 _Biomedical Computing_, and Carsten Reinhardt also discusses Lederberg in his 2006 book on physical instruments and methods in chemistry.

      I absolutely agree that there's "social stuff" (money, a symbolic currency of credibility and prestige, etc.) behind trendy scientific labels, and there are no doubt some general processes that we can trace through, to pick a few examples, the "biophysics bubble" (as Rasmussen put it), molecular biology, molecular everything, neuro-everything, and "translational medicine" (which implicates public and private interests in especially interesting ways, I think). Scientists are people, embedded in institutions, pursuing interests (financial and otherwise), and we'd be crazy to forget it. I suspect that once can follow the -omics money back to some familiar characters - academic medical centers, biotech VC, pharmaceutical firms - following the HGP blueprint (the "success" of the HGP, and how different parties have defined it, is another very important question).

      Still, I'm pretty committed to the belief that there are intellectual conditions and consequences of the particular terms in which they choose to pursue these interests. What makes "-omics" (and not some other term) the current trend? Surely the HGP has a lot to do with it, but there seems to be a lot more conceptual baggage carried over from genomics than there was, for example, with the "Manhattan Project for X, Y, and Z" of the cold war era.

  2. I noted this briefly in my blog post but the Obama administration launched a "materials genome project" last year: http://materialsinnovation.tms.org/genome.aspx

    It draws on concepts from the HGP, of course, as well as the national nanotech initiative -- all done with the intent to speed up and foster more "innovation." A nice confluence of trendy ideas and recent "big tech" initiatives.

    1. Do you think that there's more to be gained by reflecting on the metaphorical logic of the "materials genome project"?

      Like evolutionary computation, the MGP seems to fall into a category of double-reverse metaphor.

      In the case of evolutionary computing: DNA is like information --> DNA is information --> hey, since DNA is information, how we can use it to improve our information technology?

      In the case of the materials genome project: genes correlate with material sections of DNA --> genes are DNA, and we can map both at the same time --> hey, since can we mapped our genome, can we map the relationships among other important materials? (Or something like that.)

      Or perhaps, as you suggest, the materials genome project is better understood as an effort to bring together independent initiatives like nanotech and the HGP into a kind of interdisciplinary supergroup. Call it the Traveling Wilburys of technology?

  3. It seems chemomics would be the next progression in pharmaceuticals. People are looking for a fusion of medical and natural science and this would help to deliver it.
