Chaos has erupted in Egypt this week as protests calling for the removal of the president Hosni Mubarak turned violent. I do not mean to say that the conflict is as simple as pro or anti government groups, I know it is a complex issue. But as a disclaimer, I’m not a political writer, or an international relations writer.

From Novelist to Lepidopterist
My first encounter with Vladimir Nabokov was in my high school AP English class. My teacher Mr. Kaplow (author of Me and Orson Welles, which fun fact: is a movie starring High School Musical’s Zac Efron) kept a movie poster of Lolita (based on Nabokov’s most well known novel) hanging on the classroom wall.
I next encountered Nabokov while working through my undergraduate English major. Due to his Russian roots, Nabokov fit nicely into the course materials for my international literature class. I read his memoir Speak, Memory which talks a lot about Nabokov’s interest in lepidoptery, the study of butterflies.

I bring up Nabokov and his butterfly hobby because I just read an article on Nabokov’s scientific theories in the New York Times. Nabokov’s theories were dismissed by lepidopterists during his lifetime, but genetic analysis has shown that he was exactly right about the origin of a group of butterflies known as the Polyommatus blues. Nabokov theorized that the butterflies had originated in Asia and come to the United States in waves, but in the 1960’s and 1970’s no one took him seriously.
Researchers at Harvard University (where Nabokov was curator of lepidoptera at the Museum of Comparative Zoology) decided to do a genetic analysis on the butterflies to test Nabokov’s 30-year-old theory. The results showed that Nabokov was right all along, Polyommatus blues are genetically linked to butterflies in Asia. Genetic analysis has also been used to validate Nabokov’s hypothesis that Karner Blue Butterflies are a distinct species.
By this point you might be wondering why it matters that this long dead Russian novelist has been vindicated as a legitimate scientist by new technological advances, so I’ll get to my point. Nabokov is an example of how members of the scientific community can be quick to dismiss the work of anyone who isn’t an expert.
If we hold anyone who does scientific research to the same standard of peer review (analysis by other scientists, and the ability to replicate a study or experiment and get the same results as the original researcher) then even people who don’t have their doctorate in a specific science can still contribute new knowledge.
Please note that I’m not advocating that any quack with a theory should be taken seriously by the scientific community. But if promising research or theories are developed by people who might not call science their profession, their value should still be evaluated.
Revising Taxonomy
Very few people in the United States give a damn about the Egyptian Jackal. While I have nothing to offer as proof of this, I stand by my hunch that this specific canid isn’t high on the list of most popular animals, because really, who has even heard of it before? (I hadn’t until today…)

Why then should people care that genomic analysis has revealed that the Egyptian Jackal is actually a wolf, not a jackal at all? Well, because even if you don’t find the power of genomic analysis fascinating (like I do) this revision of current taxonomy (the classification of species based on how they are related to each other) is a great example of how science is a fluid thing that continually changes as new things are discovered. I think that understanding how even accepted scientific information can change is a hurdle that many people have to clear before they can really start to follow science in the news.
For years, the Egyptian Jackal (Canis aureus lupaster) was believed to be a subspecies of the Golden Jackal (both species that call parts of Africa home.) Researchers from the University of Oslo (Norway) noticed physiological differences (ie: differences in the way it looked) between Egyptian Jackals and other Golden Jackals, which led them to pursue a genetic analysis.
Sequencing the Egyptian Jackal’s genome has shown that it is a closer evolutionary relative to wolves found in India and the Himalayas (even to the United States’ Grey Wolf) than to Golden Jackals. Revising the taxonomy could have important impacts on conservation efforts. If Canis aureus lupaster (now renamed the African Wolf — and the only wolf now known to live in Africa) is a distinct species, an evaluation needs to be done to see how many members of this species there are, to determine if it is endangered.
I like this story because its a great example of how scientists are constantly revising accepted information the more they learn. However, I think when you tell people that science is constantly changing it is important to distinguish between making a revision and being flat out wrong. Scientists weren’t just wrong in their taxonomy. The Egyptian Jackal/African Wolf is a canid, so that part of the taxonomy was and still is correct. The genetic analysis enabled research to put the species into an even more specific category.
So when we say that science changes, we mean that it gets more specific and thus more accurate. But that doesn’t mean that the scientists who came before had everything all wrong. Often when scientists revise information their predecessors/colleagues were close, but didn’t have the necessary tools to learn enough to get things exactly right. There is always more that scientists can learn, and as they do, they fine tune, which is the case with the Jackal/Wolf taxonomy.
For more on the Jackal/Wolf revision, the research paper was published in PLoS One.
Can Journalists Be Celebrities?
I’ve been thinking a lot lately about the distinction between television news personalities, and print/internet journalists. I feel pretty strongly that being a TV news anchor, doesn’t necessarily make you a journalist. But then what does make someone a journalist?
To Test, Or Not To Test: A Regulatory Question
My internship with BioTechniques dumped me headfirst into the world of genome sequencing. One of the hottest (and by that I mean most talked about, funded, and hyped up) biotechnology fields, genome sequencing has a lot of power. The media loves genome sequencing because it attracts a lot of public interest, so its no wonder the technology is a headline maker.
For those who are unfamiliar with the term, genome sequencing is a process by which a machine takes a sample of your DNA (from saliva or blood) and “reads” it by identifying the nucleotide bases (Adenine, Guanine, Cytosine, or Thymine) that make up your personal DNA sequence. By comparing this sequence to the human draft sequence (a previously “read” and studied human DNA strand) researchers can tell if anything in your DNA sequence is out of place, indicating a chance for genetic disease.
I tried looking into personal genome sequencing companies for an article for my J800 class last semester. While I did come up with an article eventually, I decided not to pitch it on the grounds that none of the personal genome sequencing companies would make a representative available to talk to me, therefore my article was slightly off kilter. Apparently, no one wants to bother with helping a student, and if you don’t have a definite place to publish you just aren’t important enough for the corporate world to give a damn.
But, I still find personal genomics incredibly interesting, which is why the New York Times article Heavy Doses of DNA Data, With Few Side Effects caught my eye. The article takes a look at research from the Scripps Translational Science Institute that shows that people who pay money to have their genome analyzed often did nothing with the data, and even when the results indicated a higher risk for disease people didn’t feel any extra anxiety.
The results are interesting because they go against what you would think the common reaction to obtaining your genetic data would be. There has been controversy about public access to genetic information on the grounds that people won’t understand it and will thus act rashly or misunderstand their results. The new research shows that most people either didn’t do anything with the information they obtained, or consulted a medical professional before acting.
The new research doesn’t close the door on the issues surrounding personal genomics by any means. The idea that the technology and service should be regulated, and by who, and how strictly are all still prominent concerns. However, the study could serve to help policy makers decide how to regulate the industry.
