Remote-Controlled Flies 216

Posted by timothy from the careful-with-that-stuff dept.
Rollie Hawk writes "This could be a huge development for the ultra-lazy (and ultra-stinky, for that matter). It seems that Yale scientists have managed to engineer a remote control system for flies. According to their study (recently featured in Cell), specific neurons can be stimulated by lasers to control basic functions in fruit flies such as jumping, walking, and flying. The study, of course, was performed with wider ranging applications in mind than bringing new meaning to the saying, "Shew, fly!" The overall goal was to determine whether isolated-neuron stimulation could be used to control basic motor activities and even more complex behavior. Everyone since the days of Mary Shelly has obviously known that there are connections between electrical current and muscle movement. What makes this study unique is that it does not use traditional electrodes, which lack the single-neuron specificity of lasers. Eventually, this could lead to mappings that will give humans knowledge and possibly control over not only complex movements but less-than desirable mental functions such as aggression and overeating."

    I once saw a fly racing competition where the contestants must get their flies to weave through a course.

    They used water pistols filled with fruit juice. Flies' response time was slow but accuracy was extremely high.

          The one thing about all those "pro MSG" sites was that they all refer to mono-sodium glutamate as simply "glutamate", saying it's found naturally in proteins and in out bodies. Glutamate is an essential and natural amino acid. That's fine, but is plain old "glutamate" the exact same as MSG? MSG might be based on glutamate, but chemicals can change drastically if you add or remove extra elements. Anyone know more?

              whilst true that high levels of glutamite can cause neuron death due to excitotoxicity, the brain does have defenses against it (in fact when glutamite levels shoot up high, the brain releases an NMDA-antagonist similar to ketamine, to protect against excitotoxicity).

              Glutamite is also coverted in the brain to GABA, another amino acid which acts as a primary inhibitory neurotransmitter, which counters glutamite and other excitory neurotransmitters. So it really isn't so cut and dry.

                I guess it's just cheaper than the flavour it replaces. That is, if you can replace e.g. half of all the flavour by cheaper MSG, then it's a win to do so.

            It's not removal most want, simply required labeling. Let the consumer decide, but give them the information to do so.

      A behaviour like over eating can't just be stopped without some kind of side effect. Behaviours need to be replaced carefully (ideally with something more constructive than over eating), as there will always be a side effect. If the behaviour is "removed" the outcome would be frustration or something else which is probably going to be negative. Whatever it is that triggered the feeling to overeat should be relearnt as something else, eg, read a book, do some exercise, etc. Eg, you can't just
