Nothing to Sneeze at: the Allergenicity of GMOs

by Charles Xu figures by Krissy Lyon Summary: People are concerned about the potential of GMO food to cause allergies. However, the technology used for making GMO crops does not necessarily make us more vulnerable than conventional breeding. Comprehensive evaluation for market approval, food safety surveillance, and adequate labeling could minimize the health risks of food allergies. Moreover, further development of technology might even enable … Continue reading Nothing to Sneeze at: the Allergenicity of GMOs

GMOs and Pesticides: Helpful or Harmful?

by Jennifer Hsaio figures by Krissy Lyon Summary: Pesticides are ubiquitous. Because they are used in agriculture and food production, pesticides are present at low levels in many of our diets.  Less obvious is the fact that many people use pesticides around their homes, and even on their skin (i.e. in the form of insect repellents). According to the NIH, the health effects of pesticides … Continue reading GMOs and Pesticides: Helpful or Harmful?

Why Roundup Ready Crops Have Lost their Allure

by Jordan Wilkerson figures by Brian Chow Summary: In the history of agriculture, no technology has been adopted so quickly and completely as genetically engineered crops. Particularly useful crops are ones that have an engineered resistance to herbicides. These crops have alluring benefits: reduced crop damage when herbicides are sprayed, easier weed management, and even the potential for environmental benefits. So what’s the problem? Herbicide-resistant … Continue reading Why Roundup Ready Crops Have Lost their Allure

Same Science, Different Policies: Regulating Genetically Modified Foods in the U.S. and Europe

by Jessica Lau figures by Krissy Lyon Summary: Government regulations for genetically modified foods vary, from relatively relaxed policies in the U.S. that focus on the final food product to strict rules in the European Union that consider the genetic engineering process used to make the food. Despite these differences, the common goal of these regulations is to ensure the safety of the food supply. … Continue reading Same Science, Different Policies: Regulating Genetically Modified Foods in the U.S. and Europe

Feeding the World One Genetically Modified Tomato at a Time: A Scientific Perspective

by Christopher Gerry figures by Kristen Seim Summary: The human population has grown at a breakneck pace and threatens to further exacerbate a problem that has worsened in recent years: chronic hunger. Genetically modified crops could help to relieve this problem by providing increased yields and being more resistant to environmental stressors. In particular, the increasing prevalence of drought has prompted the development of crops … Continue reading Feeding the World One Genetically Modified Tomato at a Time: A Scientific Perspective

How to Make a GMO

by Chelsea Powell figures by Anna Maurer Summary: Genetically modified organisms (GMOs) are organisms that have been altered using genetic engineering methods. Although genetic engineering is a common and essential practice in biotechnology, its specific use in crops is controversial. The key steps involved in genetic engineering are identifying a trait of interest, isolating that trait, inserting that trait into a desired organism, and then … Continue reading How to Make a GMO

From Corgis to Corn: A Brief Look at the Long History of GMO Technology

by Gabriel Rangel figures by Anna Maurer Summary: To date, scientists have engineered bacteria that produce medication-grade drugs, crops with built-in pesticides, and beagles that glow in the dark. While these are all relatively recent advances in scientific technology, humans have been altering the genetics of organisms for over 30,000 years. How did the original practice of selective breeding evolve into the concept of genetically … Continue reading From Corgis to Corn: A Brief Look at the Long History of GMO Technology

GMOs in My Lifetime: How Genetically Modified Crops Have Transformed Rural America

by Adam Riesselman Summary: The advent of genetically modified organisms (GMOs) has rippled through the fields and homesteads of the United States, changing the way farmers conduct their operation. Fueling both the industrialization of agriculture as well as an organic food response, GMOs have pushed the culture of farming in new directions. — An Iowa sunset on the family farm. I’m one of the kids … Continue reading GMOs in My Lifetime: How Genetically Modified Crops Have Transformed Rural America

The long awaited and much debated discovery of the pentaquark

A few weeks ago, the LHCb, an experiment at the Large Hadron Collider, announced the discovery of a new particle, the pentaquark. What is a pentaquark? Well…it’s a particle, that’s made of five quarks. A quark is one of the smallest fundamental building blocks of matter. Quarks have not been observed alone in nature, and are only known to exist as composite particles. Most commonly, … Continue reading The long awaited and much debated discovery of the pentaquark

Epiboly

After the initial phase of rapid cell divisions, vertebrate embryos must go through a variety of cell movements to form the primary axis of the body and arrange cells to give rise to different tissues.  Here an embryo of the Discus fish (Symphysodon discus) is seen undergoing these essential cell movements in a process called epiboly, during which cells migrate from the top of the … Continue reading Epiboly
