Sexual behaviour: Courting dissatisfaction
A nuclear receptor, the product of the dissatisfaction gene, has been found to regulate Drosophila sexual behaviour, probably via its action in a small subset of neurons. The results shed new light on the genetic determination of sexual behaviour.
متن کاملCourting Multidisciplinary Illiteracy
REQUIRED) This study examines the possibility that our undergraduates may become multidisciplinary illiterates as a result of the increasing breadth of content introduced into the IS field. An analysis of the top IS journals finds IS education isolated and detached from its research. Without a clear body of knowledge built within a succinct codified framework for students, the IS field will con...

The Moroccan state has long attempted to maintain tight control on “its” subjects living in Europe. Since the 1960s, the state has actively discouraged migrants’ social and political integration because this was seen as endangering the flow of remittances and creating political opposition from outside. However, the failure of these remote control policies and an ominous stagnation in remittance...
متن کاملCourting bird sings with stridulating wing feathers.
In birds and other vertebrates, most acoustic signals are produced pneumatically by moving air through a vocal apparatus. Here we describe a unique mechanism used to produce a tonal acoustic signal in vertebrates. Video recordings of the courtship displays of male Club-winged Manakins, Machaeropterus deliciosus, reveal that males produce sustained harmonic tones through interactions among oscil...
متن کاملMolecular evolution of GPCRs: Melanocortin/melanocortin receptors.
The melanocortin receptors (MCRs) are a family of G protein-coupled receptors that are activated by melanocortin ligands derived from the proprotein, proopiomelanocortin (POMC). During the radiation of the gnathostomes, the five receptors have become functionally segregated (i.e. melanocortin 1 receptor (MC1R), pigmentation regulation; MC2R, glucocorticoid synthesis; MC3R and MC4R, energy homeo...
