Biologists Marin Moravec, Professor Nancy Burley and Professor Georg Striedter conducted the study, which was published in Ethology in early November. The study also found that males that paired with more similar-sounding females gave more help to the females when they were nesting.
Budgerigars, small Australian parrots commonly kept as pets, produce highly variable contact calls. Previous research showed that male budgerigars spontaneously imitate the calls of females that are potential mates. In addition, females were known to prefer males that had been trained to produce calls similar to theirs. The current study is important because it shows that female budgerigars preferentially pair with males that sound like them at their first meeting, before any imitation has occurred.
Parrots display a gift, rare among most animals, of learning new vocalizations throughout their lifetime. A highly social, monogamous species, the budgerigar likely uses multiple aspects of vocalizations when choosing mates and maintaining long-term relationships. This study adds to our understanding of the social functions of vocal learning. It also provides an interesting avian example of a familiar mate choice strategy: choosing a mate with whom you have something in common.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
