Why some aphids can't stand the heat

Researchers found that a single gene in symbiotic bacteria determines aphid thermal tolerance. The gene's mutation affects heat-shock protein production, leading to reduced reproduction and survival in hot conditions. This discovery highlights the critical role of symbiotic bacteria in insect ecology.

Lemurs' fur color may not define species

A recent study published in BMC Evolutionary Biology found that lemurs with strikingly different coat colors are genetically related and belong to the same species. The research analyzed mitochondrial genes from 70 mouse lemurs, showing they all belong to Microcebus griseorufus, regardless of their geographical location.

High-status monkeys ignore the interests of riff-raff

A study found that high-status male macaques took longer to follow the gaze of other dominant monkeys compared to low-status individuals. The researchers suggest that testosterone levels in high-status males may suppress social vigilance, a trait often seen in low-status males.
