Thanks to the miracles of
genetic engineering, one day vegetables may very well give off light of their own. At this very moment, post-doctoral students at the
University of Hertfordshire are attempting to cross the
pine tree with genes from
fireflies or fluorescent
jellyfish to get a self-illuminating Christmas tree (
just like the one Jesus had!). It would be a small step (I would imagine) to use the same technique on cucumbers or
eggplant.
Of course, whether or not this is a good thing is entirely a matter of opinion.
