There is potential for use in many fields if this study could go more in-depth. Think public transportation lines that follows a branched network now.

Although a loop network might not work(for instance the roads around city), there could be a more sophisticated loop network that is yet to be invented that can potentially solve many problems of human’s flow(in a general sense) today.

Tree branches have inspired efficient transit networks, but a new study finds inspiration in leaves. The curvy, connected leaf veins found in some plants are an efficient way to circumvent damaged areas and channel nutrients, report researchers led by Eleni Katifori of the Rockefeller University in New York City.

“It’s obvious that if you look at leaves, they have a lot of loops,” Katifori says. To find out how the looped networks may be beneficial for the plants, the researchers created a computer model to compare how efficiently different branching patterns could do the job of leaf veins, which move water and nutrients around. “The question we’re asking is, what’s the best network we can build?” Katifori says.

In the simulations, the looped network performed better than nonlooped ones in several important ways, the team reported Jan. 29 in Physical Review Letters. Damage from hungry insects, cold weather or parasites can interrupt leaves’ normal venation patterns. Connected circular veins allowed the flow of water and minerals to circumvent areas where veins were destroyed, the team shows. The looped network also allowed leaves to easily adjust the flow rate of water through veins, which can help leaves conserve water on a hot day, Katifori says.

Loop networks aren’t found just in tree leaves. Blood vessels in the retina, structural veins in insect wings and the architecture of certain corals are all based on loops, the researchers write. Understanding the benefits of such networks might lead to more efficient man-made network designs.
