In studies of rapidly growing fruit fly larvae, they've traced this developmental phenomenon to the activity of a gene called Anaplastic Lymphoma Kinase (ALK). "ALK breaks the link between dietary nutrients and neural growth," said Alex Gould of the Medical Research Council's National Institute for Medical Research in London.
