How do flies determine their escape paths? Scientists have answered this question by studying video footage of a wingless fly attempting to take to the air. The question of whether a fly will move ...

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 ...

One way to investigate the evolution of flight-associated behaviours is to monitor an animal’s response to weightlessness generated by the parabolic-flight method used for astronaut training.

The Drosophila embryo's midgut forms with an endodermal layer (green) encased by visceral mesoderm (blue). Three constrictions divide the gut, with Wingless (magenta) shaping the middle one. "We knew ...
