A large-scale experiment found that punishment consistently increases cooperation, but its effect on collective welfare varies depending on factors such as communication, contribution framing, and interaction duration. The study suggests that these elements interact in complex ways, with communication being the most influential factor.
A new analysis from UC San Francisco argues that diagnostics are being overlooked, slowing progress against major diseases despite advances in targeted therapies. The study suggests that nearly half of the world's population lacks adequate access to diagnostics due to inadequate investment and insurance reimbursement.
Researchers at the University of Texas at Austin observe permanent fission in wild chimpanzees, resulting in sustained intergroup violence. The findings suggest that relational dynamics can drive polarization and lethal conflict in chimps without language, ethnicity, or ideology.
