11. Groups move efficiently: army ants
"By forming three lanes of traffic during hunting expeditions, army ants in Panama come close to achieving the maximum possible rate of traffic flow. Given that army ants are blind, and that a hunting party might consist of 200,000 ants marching i...

Email12. Functioning with efficiency and innovation: ecosystems
"Richard Pascale, author of 'Surfing the Edge of Chaos: The Laws of Nature and the New Laws of Business,' suggests that businesses emulate living systems…employ self-organization. Rather than keep the system in check through strict manageme...
13. Individuals avoid contact: mosquitofish
"We identify three key rules for the social interactions of mosquitofish (Gambusia holbrooki): (i) Attraction forces are important in maintaining group cohesion, while we find only weak evidence that fish align with their neighbor’s orientat...
15. Colonies self-assemble: bacteria
"Stromatolites are colonies of bacteria that self-assemble into rock formations in tidal salt flats. Each stromatolite can make independent decisions, while maintaining communication with the colony. The workload is shared among all colony individ...
16. Cartilage cells evidence a mechanotransduction system that sends a nanotopographic signal that may help the cells to organize in an ordered arrays. Nanoprinting may be an important mechanism in cell interaction and signalling.
“The observations on the actin and vinculin distributions in the cell show that there is an internal response of the cell to the topography organized on the print master. Several cell types react to growth on nanotopographical surfaces by change...
17. Thermophilic microbes derive energy from hydrogen.
“We draw together three lines of inference to propose that the main energy source for these communities is H2.O2 and, to a lesser extent, oxidized sulfur species serve as the main terminal electron acceptors. Sulfide, long considered an impo...

I have recently heard of use of gradient in Drosophila Melanogaster segmentation during a Development Biology course. It is really interesting to discover how a whole functional organism can self-organize its morphology with only a few chemical a...

20. Bacteria turn flagella motor with light energy.
“The proton motive force (pmf) is the electrochemical potential of protons across the membrane, maintained under aerobic conditions by oxidative phosphorylation. Bacteria use the pmf to synthesize ATP, drive chemiosmotic reactions, and power...
