Feng Zhang is a pioneer in the world of genome editing and optogenetics, a method used for the study of neural circuits in the brain. Zhang has discovered and invented tools to study, diagnose and treat diseases such as autism spectrum disorder. His molecular engineering tools have helped broaden our understanding of the nervous system. Zhang received the 2017 $500K Lemelson-MIT Prize for his work in genetic research.

Blissymbol Printer

Since the mid-1960s, people with severe disabilities have been learning to communicate by using a system of symbols called Blissymbolics. Charles Bliss, who aimed to create a universally understood method of communication, invented this international language, which uses pictures instead of words, in the 1940s. Canadian therapists began teaching cerebral palsy patients how to use it in the 1960s and its use among the disabled began to spread. However, until the 1980s, those users had been unable to use the system independently.

Electronic Television

One of the foremost figures in the complex history of television is Vladimir Zworykin (1889-1982), who invented the “iconoscope,” “kinemascope,” and “storage principle” that became the basis of TV as we know it.
