The human brain undergoes complex reorganization and changes during aging. Using graph theory, scientists can find differences in topological properties of functional brain networks between young and elderly adults. However, these differences are sometimes significant and sometimes not. Several studies have even identified disparate differences in topological properties during normal aging or i...

A machine that can read printed material to the blind became a priority at the end of World War II with the appointment of a U.S. Government committee to instigate research on sensory aids to improve the lot of blinded veterans. The committee chose Haskins Laboratories to lead a multisite research program. Initially, Haskins researchers overestimated the capacities of users to learn an acoustic...
