2002 FEB 4 - (NewsRx.com & NewsRx.net) -- Biologists have observed, for the first time, a protein gradient in developing fruit fly embryos believed to trigger the division of the embryo into nervous system and different types of epidermis within complex organisms such as humans.
The scientists demonstrate visually and in experimental detail the molecular process by which an embryo begins partitioning itself for subsequent development into neural and distinct forms of epidermal tissue.
Their experiments provide final confirmation of an elegant hypothesis proposed during the 1950s by mathematician Alan Turing, who suggested that chemicals generated ...
