A seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly’s circadian clock, an innovative technique has revealed.
The flight of insects may look effortless but, as with any animal, their movements would be wildly uneven without an intricate system of neural signaling and muscle response to stabilize and steer the...

2021/8/6
Individuals are likely to prioritize food over sex after being deprived of both, according to researchers who studied this behavioral conflict in fruit flies. A new study pinpointed the precise neuro...
Now, new research from Caltech provides the first understanding into how so few muscles produce such complex flight.The findings, an advance at the intersection of biomechanics and neurobiology, are d...

Background: The recent literature indicates that a high vegetable intake and not a high fruit intake could be associated with decreased steroid hormone receptor–negative breast cancer risk.
Fruit Flies Modulate PassiveWing Pitching to Generate In-Flight Turns
In-Flight Turns PassiveWing Pitching
2015/8/25
Flying insects execute aerial maneuvers through subtle manipulations of their wing motions. Here, we
measure the free-flight kinematics of fruit flies and determine how they modulate their wing pitch...
