New research by genetic epidemiologist, Bjarke Feenstra of Statens Serum Institute, will help solve the puzzle of birth. In this episode Bjarke tells us about the new piece of the puzzle that he and his team have discovered. As a world first, they’ve been able to pinpoint a certain location in the genome of the unborn child that affects when the child is born. Here cytokine proteins seem to work as a sort of telegraph sending word along the wire, from child to mother. Signaling that the child is ready to come into the world.
