Some species of mammals can delay the implantation of their embryos until conditions are better for bearing and rearing offspring. This enigmatic reproductive strategy can help improve the odds of survival. Researchers have found some of the biological mechanisms behind this suspension of embryonic development. Similar reversible dormant states are also found in some cancer tumors.
University of Southern California and University of Chicago sociologists propose new indicators to estimate how common it is for mothers to have experienced the death of a child. In contrast to traditional measures of infant and child mortality, their results capture the cumulative impact of child loss through a mother's lifetime.
