No direct link found between rising inequality and reduced trust

Does rising economic inequality causes trust to fall in society and thus endanger social cohesion? Recent academic research appears to support this notion.

Cancer fear and discomforting thoughts impact colorectal cancer screening uptake

Men and women who worry about cancer are more likely to want to get screened for colon cancer, but feeling uncomfortable at the thought of cancer makes them less likely to actually go for the test…

The research, published in Behavioral Brain Research, was conducted by Pilar Segura and Ignacio Morgado (coordinators), Laura Aldavert and Marc Ramoneda, psychobiologists of the Institute of…

MRIs link impaired brain activity to inability to regulate emotions in autism

UNC researchers find that the bigger the differences in brain activity related to emotion regulation, the more severe the autismMRI data composite: the yellow indicates the prefrontal cortex…

Psychopaths’ brains unable to fully process punishment

Using MRI scans, researchers have revealed multiple abnormalities in the brains of psychopaths that could hinder their ability to learn from being punished.
