Childbirth has long been assumed to be the key threat to women’s survival in ancient societies. This study confirms that reproductive women in Tang Dynasty China (618–907 CE) died significantly earlier, but it also shows that biology is only part of the story.

By comparing bureaucrats’ wives, eunuchs’ wives, and Buddhist/Daoist nuns, the research reveals that social roles within marriage, especially in later life, carried substantial survival costs.

Women who never married or who entered religious life lived longer, suggesting that the interplay of biological and social factors, including reproductive risks and the social expectations of marriage, shaped women’s mortality in the past. onlinelibrary.wiley.com/doi/…

Child development is biocultural, meaning both genetics and environment shape life history outcomes.

Middle childhood (ages 5-12) represents an especially unique phase of development, with significant shifts across physical, hormonal, cognitive, and social domains integrally tied to the ecocultural context.

To understand its evolution and role in shaping life history, we offer a set of recommendations for evaluating onset and progression of middle childhood, with attention to the eco-cultural context of maturation. onlinelibrary.wiley.com/doi/…

The study aimed to assess the changes (in the two decades of 21st century), in the skinfold thickness and fat distribution in children and adolescents (aged 8-18) from Kraków, Poland.

When analyzing the data, it was noted that there was a trend towards central fat allocation, despite a decrease in skinfold thickness in some groups. This is concerning as central adiposity is associated with an increased health risk.

There were also differences between sexes - perhaps girls more often control their body weight and boys exhibiting less favourable dietary habits. onlinelibrary.wiley.com/doi/…

Our world is marked by deep geopolitical sorrow — from Gaza to Sudan and Ukraine — with trauma that echoes across generations. New research explores how war-related trauma can be transmitted epigenetically, shaping lives long after conflict ends.
