A new study finds that the age of a mother has no bearing on the risk for autism or schizophrenia in her offspring. According to the study, the genetic risks for these disorders originate in the sperm, not the egg, and are directly linked to paternal age. How might the finding reshape our perception of male-female biological clocks?
