Fruit Flies Aerial Stunts Inspire Brain Study

Budding engineers often take apart common devices, such as toasters, and put them back together again to learn how the parts make up a working system.

But budding biologists have a harder time using this approach—once a living organism is taken apart it usually can’t be made to function again.

Now, using modern genetic engineering techniques, researchers are able to turn biological components on and off, in effect removing parts to see how each one affects the whole system.
