This research, supported by the U.S. National Science Foundation, is an important step toward helping biologists understand ...

A study reveals how the Wingless signalling pathway shapes the embryonic intestine of the Drosophila fly, activating a mechanism involved in calcium transport. The finding redefines the role of ...

A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic tissues during the ...

The cephalic furrow is a linear bend in the tissue that can be seen in the side view (yellow asterisks, upper left) or in the cross-section view (yellow arrows, upper right) in a common fruit fly ...

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...
