The notion of sharing your grandmother’s new sexual partner might seem unappealing to us, but a study of wild greater horseshoe bats reveals that female relatives regularly share male mates, yet nearly always avoid their blood relatives.
The study, published in this week’s Nature, was led by Dr Stephen Rossiter as part of a long-term collaboration between scientists at Queen Mary, University of London, and the University of Bristol. The study used genetic analysis to look at breeding patterns over 10 years in a colony of around 40 greater horseshoe bats, Rhinolophus ferrumequinum, one of Britain’s rarest bats, from Gloucestershire.
The team, funded by the Natural Environment Research Council, found that while a female might mate with the same male as her grandmother, she won’t mate with her own grandfather. As you might expect, things quickly get very confusing, for example, the study revealed several cases in which a female and her maternal half-aunt were also half-sisters on their father’s side!

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...
