LONDON (Reuters) - What would you give for a simple injection that would stop your lover from cheating?
Well, at least it works for meadow voles.
A single gene inserted into the brain can change promiscuous male rodents into faithful, monogamous partners, scientists said on Wednesday.
It may not be quite that simple to rein in human philanderers -- many genes as well as other factors are probably involved in relationships among people.
But researchers at the Yerkes National Primate Research Centre of Emory University and Atlanta's Centre for Behavioural Neuroscience (CBN) in the United States said their rodent results could help to explain the neurobiology of romantic love.
