Humans echolocation is possible by making clicking sounds and listening for the echoes. A PLoS ONE study of two blind people showed that a part of the brain usually associated with sight was activated when listening to echoes.

Cultural Carpal Tunnel

A study recently released by Isam Atroshi at Hassleholm Hospital in Sweden shows large differences in the number of carpal tunnel diagnoses between countries. The Swiss are diagnosed with the syndrome far less than people in the United States. "What accounts for the differences is still unclear, but both medical and social factors could be at play," Atroshi noted. "For instance, it could be related to obesity or to different types of work," he added.
