A primal mechanism in bacteria that keeps them in their personal Goldilocks zones — that is, just right — appears to depend on two random means of regulation, growth and division, that cancel each other out. The same mechanism may give researchers a new perspective on disease, including cancer.
The “minimal model” by Kolomeisky, Rice postdoctoral researcher and lead author Hamid Teimouri and Rupsha Mukherjee, a former research assistant at Rice now at the Indian Institute of Technology Gandhinagar, appears in the American Chemical Society’s Journal of Physical Chemistry Letters.
“Everywhere we see bacteria, they more or less have the same sizes and shapes,” Kolomeisky said. “It’s the
