How to Spot An Engineered Plant

The European Union imposed restrictions on genetically-modified foods in 2018. But making tests to spot plants that flaunt the rules has been a serious challenge.

I first set up a little laboratory in the attic at home just to grow crystals or try experiments described in books, such as adding a lot of concentrated sulfuric acid to the blood from a nosebleed which precipitates hemotin from the hemoglobin in the blood. That was quite a nice experiment. I still remember it. -Dorothy Hodgkin
