Researchers have shown how different swimming formations may save fish energy and suggest that they only switch positions to save energy for the group when under pressure.
Georgia Tech researchers wanted to understand precisely how blackworms execute tangling and ultrafast untangling movements for a myriad of biological functions. To investigate, they linked up with mathematicians at MIT to understand the topology of the tangles. Their research could inform the design of fiber-like, shapeshifting robotics that self-assemble and move in ways that are fast and reversible. The study also highlights how cross-disciplinary collaboration can answer some of the most perplexing questions in disparate fields.
Body Copy * Cilia, microscopic hairlike structures found along the bronchi (air passages throughout the lungs), are the first line of defense against environmental pollutants, viruses and bacteria. But we know little about how they are arranged, how they move or even how they are oriented–all factors which likely impact how well they defend and protect our airways. With support from the National Institutes of Health, researchers from the USC Viterbi School of Engineering and the Keck School of Medicine of USC are working to bridge mathematical models of cilia behavior to biological and path...
