Scientists have come up with a blue strawberry by splicing them with fish genes

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. Would you eat blue strawberries?
