The Very Real Danger of Genetically Modified Foods - Ari LeVaux

The Very Real Danger of Genetically Modified Foods - Ari LeVaux
New research shows that when we eat we're consuming more than just vitamins and protein. Our bodies are absorbing information, or microRNA. Update 1/12: Thanks to science and biology bloggers, Christie Wilcox and Emily Willingham at the Scientific American blog network and The Biology Files, respectively, we've learned of the scientific inconsistencies made in Ari LeVaux's most recent Flash in the Pan column, which is syndicated by a number of newspapers and magazine websites. This column has been expanded and updated for AlterNet, with LeVaux discussing specific improvements in the comments. Chinese researchers have found small pieces of rice ribonucleic acid (RNA) in the blood and organs of humans who eat rice. The Nanjing University-based team showed that this genetic material will bind to receptors in human liver cells and influence the uptake of cholesterol from the blood. The type of RNA in question is called microRNA (abbreviated to miRNA) due to its small size. And:

How Genetically Modified Foods Could Affect Our Health in Unexpected Ways January 11, 2012 | Like this article?

GMO Myths and Truths Genetically modified (GM) crops are promoted on the basis of a range of far-reaching claims from the GM crop industry and its supporters. They say that GM crops: Are an extension of natural breeding and do not pose different risks from naturally bred crops Are safe to eat and can be more nutritious than naturally bred crops Are strictly regulated for safety Increase crop yields Reduce pesticide use Benefit farmers and make their lives easier Bring economic benefits Benefit the environment Can help solve problems caused by climate change Reduce energy use Will help feed the world.

What is MicroRNA? MicroRNAs are a class of post-transcriptional regulators. They are short ~22 nucleotide RNA sequences that bind to complementary sequences in the 3’ UTR of multiple target mRNAs, usually resulting in their silencing. MicroRNAs target ~60% of all genes, are abundantly present in all human cells and are able to repress hundreds of targets each. These features, coupled with their conservation in organisms ranging from the unicellular algae Chlamydomonas reinhardtii to mitochondria, suggest they are a vital part of genetic regulation with ancient origins. MicroRNAs were first discovered in 1993 by Victor Ambros, Rosalind Lee and Rhonda Feinbaum during a study into development in the nematode Caenorhabditis elegans (C. elegans) regarding the gene lin-14.

So what is blended learning and how can it help English Language Learners? Regulators Discover a Hidden Viral Gene in Commercial GMO Crops by Jonathan Latham and Allison Wilson How should a regulatory agency announce they have discovered something potentially very important about the safety of products they have been approving for over twenty years? In the course of analysis to identify potential allergens in GMO crops, the European Food Safety Authority (EFSA) has belatedly discovered that the most common genetic regulatory sequence in commercial GMOs also encodes a significant fragment of a viral gene (Podevin and du Jardin 2012). This finding has serious ramifications for crop biotechnology and its regulation, but possibly even greater ones for consumers and farmers. This is because there are clear indications that this viral gene (called Gene VI) might not be safe for human consumption.

A Look Inside - Flipped Posted By Meris Stansbury On February 9, 2012 @ 2:39 pm In Curriculum,eClassroom News,school reform,School Reform News,Top News | Teachers say that even though the pilot is over, they won’t go back to the old way of teaching. There have been many school reform trends over the past few years: student response systems, video games for math, mobile phones for learning—but none have completely transformed the notion of learning like the flipped classroom. Flipped learning [2], in essence, turns the idea of traditional classroom instruction on its head by asking students to watch videos of teacher lectures for homework, then apply the lesson with the teacher in the classroom. Using this method, proponents say, teachers have the opportunity to help students learn as individuals, and students can learn concepts more quickly.

GMO Salmon Can Reproduce: Meet the Terrifying Offspring It doesn’t happen often in nature, but now and then, a wild Atlantic salmon (yes, there are still a few left) mates with a brown trout and has hybrid offspring. This ability to reproduce between species had some Canadian scientists curious: If a genetically modified Atlantic salmon were to come in contact with a brown trout, would it too be able to have little transgenes babies? The answer is yes, according to a new study published in the Proceedings of the Royal Society B . And it turns out that those offspring carry the genetically inserted trait that allows them to grow faster than their Mother-Nature-made cousins. Much faster. In fact, the hybrid offspring outgrew their genetically tweaked parents as well.
