Scientists are genetically modifying strawberries in order to allow them to resist freezing temperatures better. They're doing it by artificial transfer of genes from a species of fish called the Arctic Flounder Fish. The Arctic Flounder Fish produces an anti-freeze that allows it to protect himself in freezing waters.
They isolated the gene that produces this anti-freeze and introduced it to the strawberry. The result is a strawberry that looks blue and doesn't turn to mush or degrade after being placed in the freezer. While they're not in production, research is ongoing. Let us know in the comments, would you eat blue strawberries?
