Washington, Sept 23 : Ever wondered why a song sounds sexy sometimes and annoying at other times? Well, a study on songbirds has shed new light on this question, showing that a change in hormone levels may affect the way we perceive social cues.

Emory University’s Donna Maney, who used white-throated sparrows for the study, says that the changes in hormone levels affect the perception by altering a system of brain nuclei, common to all vertebrates, called the ‘social behaviour network.’

"Social behaviours such as courtship, parenting and aggression depend primarily on two factors: a social signal to trigger the behaviour, and a hormonal milieu that facilitates or permits it," said the study leader.

Washington, September 23 : A long-term study of mammal fossils spanning a 5-million-year period in northern Pakistan has suggested that two species of giraffe, several rhinos and five elephant relatives, along with multitudes of rodents, bush pigs, horses, antelope and apes, once inhabited the region.

University of Michigan paleoecologist Catherine Badgley and coworkers conducted the study.

Washington, September 23: Paper wasps can remember their meeting with an individual for at least a week, even after interacting with many others in the meantime, say University of Michigan researchers.

The discovery made by graduate student Michael Sheehan and assistant professor of ecology and evolutionary biology Elizabeth Tibbetts suggests that the social interaction among wasps may be based on memories of past encounters, instead of on rote adherence to simple rules.

Writing about their findings in the journal Current Biology, the researchers agree that honeybees, too, can remember where they have found nectar.
