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…
Exosome-mediated chemotaxis optimizes leader-follower cell migration
Louis González, Andrew Mugler
Cells frequently employ extracellular vesicles, or exosomes, to signal across long distances and coordinate collective actions. Exosomes diffuse slowly, can be actively degraded, a…
Moo-ving mountains: grazing agents drive terracette formation on steep hillslopes
Benjamin Seleb, Louis Gonzalez, Atanu Chatterjee +1
Terracettes, striking, step-like landforms that stripe steep, vegetated hillslopes, have puzzled scientists for more than a century. Competing hypotheses invoke either slow mass-wa…
Quantifying cellular autonomy in multi-cue environments
Louis Gonzalez, Hogyeong Gwak, Bumsoo Han +1
A cell routinely responds to one of many competing environmental cues. A fundamental question is whether the cell follows the cue prioritized by its internal signaling network or t…
Collective effects in flow-driven cell migration
Louis González, Andrew Mugler
Autologous chemotaxis is the process in which cells secrete and detect molecules to determine the direction of fluid flow. Experiments and theory suggest that autologous chemotaxis…
