Contraception and castration linked to longer lifespan

A new study published in Nature found that contraception and castration increase life expectancy in both males and females. In males, castration extends lifespan, while in females, various forms of sterilization are associated with increased life expectancy due to reduced energetic costs of pregnancy and lactation.

Rethinking climate migration

A new concept, tethered resilience, challenges the traditional 'move' or 'stay' dichotomy in climate migration. Individuals and families are drawn to alternative strategies that balance economic, social, and cultural factors. This approach recognizes the importance of social infrastructure and networks in enabling adaptation and future...

MIT researchers identified three cognitive skills we use to infer what someone really means

Researchers at MIT have identified three clusters of pragmatic skills that are based on the same kinds of inferences and may have similar underlying neural processes. These skills include interpreting social conventions, understanding physical world knowledge, and distinguishing between tones to convey emphasis or emotion.
