In-flight brain recordings from fruit flies
CALTECH (US)—The first recordings of brain-cell activity in a flying fruit fly suggest that at least part of its brain “is in a different and more sensitive state during flight than when the fly is quiescent,” says researcher Michael Dickinson. (more…)

What’s the new story on fruit flies?
CALTECH (US)—For decades, science texts have told a simple and straightforward story about a particular protein—a transcription factor—that helps the embryo of the fruit fly, Drosophila melanogaster, pattern tissues in a manner that depends on the levels of this factor within individual cells. (more…)

Fruit flies killed by nanoparticles
Microscopy shows a clean foot and leg of a fruit fly (top), and a foot and leg covered with carbon nanostructures (bottom). Adhering nanostructures may have impeded movement, respiration and vision in adult flies but did not appear toxic to fly larvae that ingested it.

Pumping up (the proteins) to get the girl
CORNELL (US)—When it comes to wooing females, males of all species—even fruit flies—try to gain a competitive edge. A new study shows that in the presence of another competitor, male fruit flies pack more proteins into their seminal fluid, boosting their reproductive success. (more…)
