Deciphering the hidden interactions within biological networks of varying sizes
Researchers from the University of Tsukuba discovered that fish schools showed a significant change in behavior with varying school sizes. Using integrated information theory, they showed that a significant change in the interaction between the fish and the overall collective behavior occurred between three- and four-fish schools, including the emergence of leadership within the group. These findings help understand the dynamics of collective behavior. (2020-05-07)

Jurassic Park got it wrong: UW Oshkosh research indicates raptors don't hunt in packs
A new University of Wisconsin Oshkosh analysis of raptor teeth published in the peer-reviewed journal Palaeogeography, Palaeoclimatology, Palaeoecology shows that raptorial dinosaurs likely did not hunt in big, coordinated packs like dogs. Though widely accepted, evidence for this behavior is relatively weak. Recently, scientists have proposed a different model for behavior in raptors that is thought to be more like Komodo dragons, in which individuals may attack the same animal but cooperation is limited. (2020-05-06)

Cultivating cooperation through kinship
Extensive cooperation among biologically unrelated individuals is uniquely human. It would be surprising if this uniqueness were not related to other uniquely human characteristics, yet current theories of human cooperation tend to ignore the human aspects of human behavior. This paper presents a theory of cooperation that draws on social, cultural, and psychological aspects of human uniqueness for which current theories have little or no explanation. (2020-04-30)

Instagram and the male body image
In a new study among males depicted on Instagram, the majority of posts showed men with low body fat, while only a small fraction depicted men with high body fat. Sixty-two percent of posts showed men with low body fat and 41% showed high muscularity, whereas only 6% showed men with high body fat and 17% showed low muscularity. (2020-04-27)

(2020-04-13)

I won't have what he's having: The brain and socially motivated behavior
Monkeys devalue rewards when they anticipate that another monkey will get them instead. Researchers from the National Institutes of Natural Sciences in Okazaki, Japan showed that cells in the lateral hypothalamus mirror these changes in subjective value based on social observations. Further, temporary inactivation of this region prevented the behavior from occurring. The lateral hypothalamus might thus be involved in modulating socially motivated behaviors in primates, including humans. (2020-03-27)

Birds exposed to PCBs as nestlings show behavior changes as adults
According to a new study, Zebra Finches exposed to low levels of environmental PCBs as nestlings show changes in breeding behavior as adults. (2020-03-26)

Neither nature nor nurture: Behavioral individuality in fruit flies' neurodevelopmental origin
While some fruit flies wander, others prefer to walk the straight and narrow; the origin of these behavioral quirks in individual flies may be a product of random variation in how neural circuits are wired during brain development, a new study of fruit flies given 'lines to walk' finds. (2020-03-05)

Reducing problem behaviors for children with autism
Self-inflicted injury, aggression toward others and yelling are common problem behaviors associated with young children diagnosed with autism spectrum disorder.
