Allen Institute, put numbers on the internal organization of human cells — a biological concept that has proven incredibly difficult to quantify until now. All this to ask one seemingly straightforward question: How do our cells organize their interiors?The scientists wanted to know: How do all those tiny cellular structures arrange themselves compared to each other? Is “structure A” always in the same place, or is it random?The team ran into a challenge comparing the same structure between two different cells. In these two states, the scientists were able to find changes in internal organization correlating to the cells’ different environments or activities
