Why shaking faster does not untangle: frequency-selective extraction of filaments from tangled matter
Ishant Tiwari, Sutikshan Bansal, Rosalind Huang +4
Tangles of soft filaments are ubiquitous, from living worm blobs to the cables in a desk drawer. How do such tangles, held together by friction and entanglement, respond when one e…
A developmental switch from capillary rectification to elastic catapult enables honeydew ejection in the spotted lanternfly
Nami Ha, Elio J. Challita, Jacob S. Harrison +4
Plant sap-feeding insects must dispose of excess fluid, yet at millimeter scales droplet release is constrained by capillary adhesion and contact-line pinning. How phloem-feeding i…
Seabird trajectories map onto a reduced optimal-control bound for dynamic soaring
Louis González, John P. Y. Arnould, Saad Bhamla
Dynamic soaring allows seabirds to harvest mechanical energy from vertical wind shear, yet there is no common benchmark for comparing flight performance across species based on the…
Collecting Particles in Confined Spaces by Active Filamentous Matter
R. Sinaasappel, K. R. Prathyusha, H. Tuazon +4
Biological and robotic systems often operate in confined environments where material must be gathered without centralized control. Inspired by the effective collection strategies o…
