Researchers found that prairie voles show empathy by grooming or consoling another individual that appears to be distressed. This could be a major breakthrough for better understanding of psychiatric disorders in humans, including autism spectrum disorder (ASD) and schizophrenia.
Most species avoid crowding but prairie voles seem to be the exception to the rule, say Duke University researchers who found that voles become less anxious and stressed when they have to share their personal space.
Japanese macaques are exposed to various stressful situations in the wild, including rank fights and mating competitions. Researchers recently took a closer look at how genetics ultimately control the release of stress hormones in these animals.
The feel-good hormones and other great results come from hanging around outdoors. Studies on this go back to a record 1984 finding that people with hospital room windows healed faster.
Researchers recently discovered that if elephants are born during times when their mothers are more stressed, they are likely to age faster and reproduce less during their lifetime.
