A new study reveals that beers could influence people's social and sexual perception, making them happier and more friendly.
New research suggests that the immune system can produce what one might call a "social molecule" that facilitates pro-social behavior... and blocking it can cause a personality disorder.
Despite huge increases in life expectancy in both groups, rich people's lives are still extending faster, academics from Cass Business School and the International Longevity Centre-UK (ILC-UK) found.
Male bluebirds benefit from spending a year at home before moving out to build a nest of their own, according to a new study from Cornell University and the Santa Fe Institute. Researchers say the cooperative behavior, or rather helping out around mom's nest, improves the birds' life span and increases genetic diversity of offspring, as females prefer mating with older males.
Strange green flatworms, also known as "mint-sauce worms," collect together in shallow waters along much of Europe's Atlantic coast, forming what researchers call a "superorganism." It is believed that this social behavior helps protect the animals and aids in their photosynthetic feeding.
Killer whales have been studied for the first time in their North Atlantic range. Compared to their Pacific Northwest counterparts that feast on Chinook salmon, the Atlantic dwellers prefer preying on minke whales.
Like bees, ants organize their colonies based on social rank. It appears trap-jaw ants engage in antenna-boxing matches to dictate who guards the colony and who goes out into the world to forage.
Chimpanzees are less inclined to groom one another with numerous bystanders lingering about. This challenges the long-held belief that such cooperative behaviors are based on trust, suggesting they revolve more around immediate benefits.
When shown pictures of an unfamiliar human with a threatening facial expression, horses become stressed and view the image using their left eye. While similar behaviors have been documented in domestic cats and dogs, this is the first time researchers have found horses can interpret the different emotions of their handlers, too.
Aggression is fairly common among primates, but a lethal attack among Bornean female orangutans was documented for the first time in a recent study.
A recent study on Eurasian Siskins proves that smaller birds prefer to travel in groups like their larger counterparts, swans, geese and crows.
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.
Researchers found domestic dogs can tell the difference between a threatening and pleasant facial expression by gazing into one's eyes. This is similar to a human's social gazing behavior.
Human friendship is not as unique as previously thought, say researchers who tested chimpanzees and found that they are more likely to share with those they trust and consider friends.
Fish chatter with each other in order to stay close to one another and better their chances of safety. While contact calls are generally used for mating purposes or to defend one's territory, this is the first time researchers have observed fish communicating to maintain group cohesion.
