New cell imaging method shines a light on blind spots

Cells are crowded, dynamic places where thousands of molecules interact in tight quarters. Until now, scientists lacked a reliable way to see many of these molecular interactions as they happen. Researchers at the University of Illinois Chicago have now developed a new imaging method that allows scientists to see previously hidden enzyme activities in small regions across the whole cell. The findings, published in the Proceedings of the National Academy of Sciences, open new possibilities for understanding how cells process information.
