A Genetically Engineered Fly That Can Smell Light

An anonymous reader writes "It sounds like a cool — if somewhat pointless — super-powered insect: a fly that can smell light! Researchers added a light-sensitive protein to a fruit fly's olfactory neurons, which caused the neurons to fire when the fly was exposed to a certain wavelength of blue light. Adding the protein specifically to neurons that respond to good smells, like bananas, makes for a light-seeking fly."

    They could've made them think a wavelength smells terrible and then sold fly repellant lightbulbs.

      No, you see the trick is to get them attracted to light. THEN they will land on those inefficient 80W bulbs attempting to eat it and burn their 'mouths' and feet in the process.

      Right, and all they have to do is genetically engineer all the flies in the world, or at least every population of them.

      Well think about it. How many generations does it take for a favorable gene to spread trough the population? Give the flies another favorable gene as well as the smell gene, then set them loose to make babies. I read somewhere that it takes 3000-5000 years for humans, but fly generations are much shorter, so maybe we could reap the advantages in our lifetime.

      That's for favorable genes. I believe that, from the fly's point-of-view, believing that blue light is food (and potentially causing it to fly into a human-produced trap) would be all that favorable.

      You're thinking about it all wrong.

      You set up fly traps that repel the genetically modified flies. What you end up with is flies that are genetically predisposed to stay away from the areas we designate. Assuming the genetic modifications don't have any other adverse affects I would say it would be a great idea. We could have a situation develop where flies stay away from us and yet are still part of the environment and the food chain.

    Finally, we have been able to achieve what we always needed: flies that can compete with human art critics.

    On the other hand these flies are not as advanced as Arizona lawmakers, who apparently can feel if one is an illegal alien by 'looking at brands of shoes' (incidentally, will this not force the cops to hire a disproportional number of gays into service?)
