Why did The Atlantic publish this piece trying to link miRNAs and GMOs?

A study from a Chinese group led by Chen-Yu Zhang of Nanking University and published in Cell Research, has uncovered the fascinating result that when people eat rice, they can absorb microRNAs (miRNAs)–tiny sequences of RNA–from the rice into the blood. These rice-originating miRNAs turn up in blood and tissues of people who eat rice and…here’s the kicker…one type of rice miRNA interacts with human proteins that are responsible for removing LDL (“bad” cholesterol) from the blood (!). It’s the first report of plant miRNAs ending up in people by way of diet and the finding that at least one of them alters an important process in the body.

The implications could extend in many a direction, but not as far as writer Ari Levaux would like to take them in this remarkably confusing article published on the Atlantic Website. Before taking on the errors and the overstretch that are that piece, let’s look at something far more interesting: miRNAs themselves.

Precautionary Principles and the Cost of Caution

She felt terrible, with a horrible pain in her gut that cut like a knife, and nausea and fever to match. Usually stoic in the face of pain, my daughter was doubled over and gasping.

When we took her to the hospital, the doctor took one look at her and immediately ordered a scan. Within hours she was in the operating room to have her ruptured appendix removed. After the operation, the surgeon showed us pictures of the process, including a glossy photo of the inflamed appendix and the staple he had used to close off the end from which it had been removed. Almost immediately after surgery, my daughter’s fever diminished. Her post-surgical pain was minimal compared to the searing pain that brought us to the hospital in the first place. As I write this, she is still in the hospital where she will remain for a few more days. But the crisis is over and there is improvement by the hour. By the time you read this, she will probably be home again in her own bed.

Planting for a Greener Yield

Over the last 15 years, agriculture has been changing technologically at an amazing pace. It is something that is truly fun to look back at and realize where we have come. As a producer of corn, soybeans, wheat, seed corn, and popcorn over many of those years it has truly changed what we are able to do and what we will be able to do in the future.

Equipment technology has created a way for us to be able to be better stewards of our ground and resources. Biotechnology has allowed us to push the food, feed, and fuel production to levels that only a few short years ago, many people would not have thought possible. Plus, we are utilizing fertilizer at a better rate.

Non-traditional Comestibles Suitable for Holiday-specific Ingestion

Before Thanksgiving break, my plant systematics professor told us that if we handed her a list of the scientific names of every plant species we consumed over the holidays we would get extra credit. I toyed with the idea of simply rewriting a recipe to include the latin names but considered that too easy. Instead, I’d have to go all out and write a full-on academic paper of my holiday experience. Since this would also be my first Thanksgiving away from home, I had cause to experiment. What follows, then, is my extra credit assignment:

The Right to Know: Why GMO Labeling Law Isn’t So Black and White

Consumer advocacy groups are a strange animal. It seems that for every influential lobbying group with a senator’s ear, there are hundreds or thousands with only vague mission statements and no clear agenda for attaining their stated goals. I once spent a summer working for the latter type. A hallmark of this kind of crew is the use of the petition (bonus points if it’s online and has been circulating for more than a year). Issue-specific petitions almost never work when directed at agencies; they are often unsophisticated (in a legal sense) and rife with ambiguous language and emotional rhetoric. If I were more cynical, I might point out the possibility that many people in charge of these groups are aware of their petitions’ minuscule chances for success and instead use them to gin up controversy and interest in their cause, which is always a great way to get a few email addresses or financial contributions–some petitions even have a convenient donate button right next to where you “sign” your name!

A quick google search for “gm labeling petition” pulls up, well, more petitions than I really care to count. Most make seemingly modest demands about the “right to know,” consumer education, and truth in advertising. Is that an accurate view of the debate: Consumer education versus corporate secrecy? Truth is, the legal reality is a little more complex than these petitions would seem to indicate. Below, I’ve written a short synopsis of the government’s current stance on GMO labeling. It’s written for people without any legal training, so it’s only a sketch. I’ve also listed a few helpful resources at the bottom for anyone who wants to dig a little deeper. This is exclusively about U.S. law, but in future posts, I’ll discuss recent developments in the biotech laws of Canada, the European Union, and Japan.
