New Discovery by Physicists Changes Thoughts on Human Sight

Isomerization of retina

"A discovery by a team of researchers led by a Syracuse University physicist sheds new light on how the vision process is initiated," according to MedicalNewsToday. "For almost 50 years, scientists have believed that light signals could not be initiated unless special light-receptor molecules in the retinal cells first changed their shape in a process called isomerization. However, the SU research team, which includes researchers from Columbia University, has demonstrated that visual signals can be initiated in the absence of isomerization." Read more.
