Story summary

Researchers at the Earth-Life Science Institute in Tokyo introduced global constraint principle to explain why growth slows as nutrient availability increases.
The principle integrates Monod equation and Liebig's law of the minimum, presenting a 'terraced barrel' model that shows growth limits.
Simulations of Escherichia coli show that when a nutrient is abundant, other constraints like enzyme capacity emerge, with implications for biotechnology, agriculture, and ecology across life forms.
