Emergent Cooperation
Category: cooperation
My good friend and labmate just published an awesome paper: "Emergent cooperation in microbial metabolism." His experiment started with 46 strains of E. coli that had mutations in their metabolic pathways that prevented them from being able to grow without...

Wireless Cellular Communication
Category: bacteria
Cells are constantly jibber jabbering, sending messages to each other to coordinate behavior, both within a population of single-celled organisms or between cells of an individual multicellular organism. Most of these signals are chemicals that float around in the liquid...

Cooperation and Experimental Evolution
Category: evolution
Cooperation and altruism are widespread in biology, from molecules and genes working together in a cell, to bacterial communities that require coordinated behavior to survive in a tough environment, to human relationships and societies. Our human cultural perspective (perhaps even...
