Experimentally activating individual worker immune responses in Bombus terrestris colonies results in reduced social unity and collective earlier reproduction. This suggests that key elements of immune defense are retained through evolutionary sociality.
A review of sociological research on family relationships highlights two dominant accounts: one emphasizing family breakdown and moral decline, while the other focuses on transformation and democratization. Despite this, a third perspective argues that there has been little substantial change in personal ties and obligations.
A new study in rats reveals that gene activity plays a significant role in brain aging and cognitive impairment. The research identified 146 genes associated with age-related changes in memory performance, including those involved in inflammation, oxidative stress, and neuronal function.

Adverse experiences in early childhood can lead to changes in brain structure, gene expression, and neurotransmitter function, increasing sensitivity to stress. This increased stress sensitivity is a significant risk factor for mood disorders and medical diseases.
A researcher challenges the idea that generations drive attitude changes in America, arguing instead that individual life experiences, aging, and historical events play a significant role. Alwin's study suggests that social change is more complex than previously thought, with multiple factors contributing to generational differences.
A study in Denmark found that pregnant women's attitudes toward drinking during pregnancy exist independently of their knowledge of the subject. A majority of women considered some alcohol acceptable, mostly on a weekly level, while binge drinking was deemed harmful. The research highlights the need for targeted health information stra...
Climate change is projected to increase extreme weather events, displacing millions and fueling conflict in low-lying countries. Biogeographical redistribution of pathogens and organisms via globalization poses a growing threat to global security.
Researchers found that repeatedly exposing people to positive images of stigmatized groups, such as African Americans and the elderly, can alter their nonconscious attitudes towards those groups. This strategy may help reduce prejudices and improve social welfare.
The study found that value messages in American primary schools primarily focus on orderliness and hard work, with modern values like cultural diversity and choice also present. Schools' organizational interests influence the interpretation of value terms, such as citizenship and self-esteem.
