When you ran your fingers along its barbs and watched the disturbed parts return to their original positions? Researchers do, and they used the shape of the barbules of a feather to develop new adhesives and aerospace materials. It has been 20 years since the last time someone performed a detailed investigation of the overall shape of bird feathers that was not limited to a single species. The new study was conducted by a research team from the University of California San Diego (UC San Diego). Team leader Tarah Sullivan oversaw efforts to print 3D structures based on the various parts of feathers from multiple species of birds. The printed shapes underwent various tests that helped define their properties. One example is the difference between the underside and the top part of the feather. The underside can generate lift for flight by catching air, while the top can keep air out when the bird needs to land. Sullivan published her team’s findings in the scientific journal Science Advances. Her paper… Read full this story
