On the scent of pleiotropy.
F rom bird songs to the great horn of the rhinoceros beetle, the gaudiest, and possibly most frequent, displays among animals occur in the context of sexual communication and reproduction.

متن کاملNeurobiology: Tracking the scent
Olfactory sensory neurons are believed to follow a ‘one-neuron-one-receptor’ rule to properly translate odor signals into the brain. However, the complexity of the olfactory system—which displays continuous neurogenesis, with more than 1,000 olfactory receptor genes expressed in several developmental stages—has limited detailed analyses. Two studies now report the application of single-cell tra...
