Genetically driven gut feelings help female flies choose a mate

Genetically driven gut feelings help female flies choose a mateResearchers at Rockefeller University have determined that the Abdominal-B (Abd-B) gene, previously known as the gene that sculpts the posterior parts of the developing fly, is also important for a complex courtship behavior, at least in the case of female flies.

New faculty member wants to know how flies make decisions

Gaby Maimon, who will join the university on January 1, has developed a unique system for studying the neural basis for decision-making in fruit flies. By using fluorescence microscopy and glass capillaries pulled to ultrafine tips, Maimon records the electrical activity of specific neurons in the fly brain as it flies, allowing him to understand what’s going on as the fly is exposed to — and reacts to — various stimuli.

New cell death pathway involved in sperm development

Good swimmers, like healthy sperm, are sleek and light. They shed extra pounds, shape their body and even shave their legs to move efficiently and fast. Sperm also remove excess baggage to function optimally, and caspases, proteins involved in apoptosis, or programmed cell death, facilitate this process. New research from Rockefeller University and the Howard Hughes Medical Institute uncovers a new pathway that regulates caspase activity in Drosophila sperm, a finding that represents a new and promising drug target for therapeutic purposes.
