Leaking away essential resources isn’t wasteful, actually helps cells grow

Experts have been unable to explain why cells from bacteria to humans leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites — substances involved in the chemical processes to sustain life with the production of complex molecules and energy — may provide cells […]
