What is déjà vu?  Many of us know the feeling. You’ll be going about your day, minding your own business, folding some laundry…nothing out of the ordinary.

Suddenly a sensation of familiarity washes over you, and you’re completely aware that it’s happening. I’ve been here before. Except you haven’t. Or have I? You might try to think back and pinpoint when you’d experienced this moment before. But just as quickly as the feeling hits you, it’s gone again.

Did you predict the future? Were you seeing something from a past life? What is déjà vu, anyway?

A recurring theme in science fiction is the ability to modify an organism’s genetic material. The goal is usually to give the modified person or creature amazing characteristics — super speed, super strength, or mind control, to name a few.

I haven’t met anyone with these features yet, but the future is already here. Scientists can modify the genomes of animals and plants with ease, though for an entirely different reason. You may be familiar with the term already: “GMOs.”

A genetically modified organism (GMO) is any living thing that has had its genome (its genetic material) modified. In general, GMOs fall into two major categories—organisms modified for research purposes and those modified for consumption.

You may be familiar with the advocacy work of the Non-GMO Project, Chipotle’s new G-M-Over It campaign, or seen social media postings from friends and family about the dangers of GMO food. But what’s the real science behind the science fiction?
