Just like watching animals in the wild can reveal more about their behavior than watching them in a zoo, watching protein molecules in their natural environment can reveal how they function. Researchers Xavier Darzacq and Robert Tjian are using microscopes to study single protein molecules in live cells. The lines in this image are the motion paths of molecules. 🟪 is faster than 🟩 By observing how proteins move and interact with each other, they hope to gain new insights into how the tiny doers of our cells keep us alive and healthy. #innovation #discovery #biology #microscopy #imaging #BioImaging #DynamicImaging #science
