HANOVER, N.H. - April 14, 2021 - Scientists have searched for years to understand how cells measure their size. Cell size is critical. It's what regulates cell division in a growing organism. When the microscopic structures double in size, they divide. One cell turns into two. Two cells turn into four. The process repeats until an organism has enough cells. And then it stops. Or at least it is supposed to.
