Study of fraternity hazing reveals little connection to group solidarity

Credit: Pixabay/CC0 Public Domain Even though it reaches deep into human history, hazing remains a puzzling behavior for social scientists. Why would people systematically abuse their own future allies by making them participate in extremely unpleasant group initiation practices? For colleges and universities, hazing has been a pressing safety issue for decades, so much that … Read more

What is the best way to group students?

Researchers from the University of Rochester and the University of Nevada have developed, for the first time, a mathematical approach to grouping theory. They compares different grouping methods and shows the best way to group individuals for teacher-led instruction.

Using renormalization group methods to study how the brain processes information

This is a snapshot taken from a numerical simulation of the two-dimensional Wilson-Cowan model with stochastic input (Eq. (3) in our paper). Yellow (blue) pixels represent high (low) activity.
