Cell Biology by the Numbers - BioNumber of the month
Cell biology is constantly being enriched by an influx of quantitative data on a host of critical quantities. In the vignettes below, that also serve as the basis for a book on “Cell Biology by the Numbers” written by Ron Milo and Rob Phillips, we explore how a knowledge of key numbers that characterize the behavior of cells can be used to make useful inferences in molecular cell biology. One of the ways we try to make sense of these numbers is by making back of the envelope calculations (so called Fermi problems) in biology. These estimates aim to connect the complexity of many problems in biology and the kinds of clear-cut deductions often used potently in the physical sciences.
