New research reveals reveals the hidden struggles experienced by the brothers and sisters of people with Prader-Willi syndrome.

The rare genetic disorder causes growth and learning challenges and requires lifelong care to prevent serious health issues. It is known for causing constant hunger, which can lead to over-eating and obesity.

Researchers at the University of Basel have developed a tool that measures when people engage in dialog across political divides. The results show that personal factors play a greater role in people’s willingness to engage in dialog than the controversial nature of a topic.
