How Much Does Life Weigh?

From earthworms and sunflowers to human beings, we are all made up of cells, so it’s no surprise that researchers are hard at work...
Coevolution

Understanding the Coevolving Web of Life as a Network

Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic...
