The low down: Superweed is a misleading term used to describe weeds that are resistant to an herbicide. It is conceptually possible that certain, herbicide-resistant GMOs could contribute to an increase in herbicide-resistant weeds; however, such concerns are not limited to GMOs, but are relevant for any crops used in conjunction with herbicides. The details: First of all, what is a superweed? According to the Weed Science Society of America (WSAA), there is “no science-based definition for superweed,” but the term is often used to describe herbicide-resistant weeds. Just as overuse of one particular antibiotic promotes the spread of bacteria resistant to that antibiotic, overuse of an herbicide can result in herbicide-resistant weeds. According to Rick Boydston of the USDA-ARS...

While Wood claims to have painted in appreciation of Midwestern culture, writers such as Gertrude Stein saw satire, and Iowans were outraged at their depiction as "pinched, grim-faced,...

Plant breeding and genetic engineering are incredibly useful tools. Like most tools, they serve distinct purposes. Plant breeding randomly combines the genes of two closely related plants. This is useful when both parents have several useful traits. Genetic engineering allows scientists to move specific genes between species. I used the following scenario to demonstrate the precision... Continue Reading →
Imagine if all the music on itunes was interrupted by blocks of white noise that you had to manually edit out every time you downloaded a song. Makes no sense right? Why would songs be recorded that way? Why not just remove the junk at the source, so you don’t have to waste time and energy? That’s... Continue Reading →
