A study comparing wild and zoo-housed Sumatran orangutans reveals that orangutans living in zoos engage in more frequent, more diverse, and more complex exploration than their wild counterparts. Zoo-housed orangutans show a richer repertoire of actions and are more likely to use tools or manipulate multiple objects at the same time.
Researchers found that dopamine signals in two key brain areas respond differently to negative experiences, helping the brain adapt based on predictability and controllability. This study sheds light on how excessive avoidance can lead to decreased quality of life and why the 'dopamine detox' trend is too simplistic.

The research team discovered a colour-dependent bias in learning speed, with chicks exposed to a deep blue mother learning faster than those raised by mothers with other colours.
Researchers re-analyzed historical data from a classic displacement experiment and found that young starlings migrated independently, using their own direction. Adult starlings adjusted their migratory orientation to reach their normal wintering areas, while local conspecifics influenced the route of relocated young starlings.

A new study reveals that praising and petting dogs enhances their learning success by reducing stress. Dogs who received a 'permissive' training style with praise and petting performed better than those in a 'controlling' style, which induced greater stress.
A study found that adult chimpanzees continue to learn and refine their tool-using skills well into adulthood, suggesting a prolonged learning capacity is key to the evolution of complex tool use in chimps and humans. Chimpanzees developed motor skills for handling sticks by age six, but continued to hone techniques until age 15.
