Kavli Affiliate: L. Mahadevan | First 5 Authors: Salem al-Mosleh, L. Mahadevan, , , | Summary: Growing a flat lamina such as a leaf is almost impossible without some feedback to stabilize long wavelength modes that are easy to trigger since they are energetically cheap. Here we combine the physics of thin elastic plates with […]
Kavli Affiliate: L. Mahadevan | First 5 Authors: S Ganga Prasath, L Mahadevan, , , | Summary: The physics of signal propagation in a collection of organisms that communicate with each other both enables and limits how active excitations at the individual level reach, recruit and lead to collective patterning. Inspired by the patterns in […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Paul B. Dieterle, Jenny Zheng, Ethan Garner, Ariel Amir, | Summary: Dynamic instability — the growth, catastrophe, and shrinkage of quasi-one-dimensional filaments — has been observed in multiple biopolymers. Scientists have long understood the catastrophic cessation of growth and subsequent depolymerization as arising from the interplay of […]
Kavli Affiliate: George M. Whitesides | First 5 Authors: Jovanna A. Tracz, Lukas Wille, Dylan Pathiraja, Savita V. Kendre, Ron Pfisterer | Summary: The control of pneumatically driven soft robots typically requires electronics. Microcontrollers are connected to power electronics that switch valves and pumps on and off. As a recent alternative, fluidic control methods have […]
Kavli Affiliate: George M. Whitesides | First 5 Authors: Lauryn Whiteside, Savita V. Kendre, Tian Y. Fan, Jovanna A. Tracz, Gus T. Teran | Summary: Developing soft circuits from individual soft logic gates poses a unique challenge: with increasing numbers of logic gates, the design and implementation of circuits leads to inefficiencies due to mathematically […]

Kavli Affiliate: Robert Wood | First 5 Authors: Kaitlyn Becker, Clark Teeple, Nicholas Charles, Yeonsu Jung, Daniel Baum | Summary: Grasping, in both biological and engineered mechanisms, can be highly sensitive to the gripper and object morphology, as well as perception, and motion planning. Here we circumvent the need for feedback or precise planning by […]

Kavli Affiliate: L. Mahadevan | First 5 Authors: Siheng Chen, Fabio Giardina, Gary P. T. Choi, L. Mahadevan, | Summary: Geometric graph models of systems as diverse as proteins, robots, and mechanical structures from DNA assemblies to architected materials point towards a unified way to represent and control them in space and time. While much […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Ella M. King, Zizhao Wang, David A. Weitz, Frans Spaepen, Michael P. Brenner | Summary: Despite significant advances in particle imaging technologies over the past two decades, few advances have been made in particle tracking, i.e. linking individual particle positions across time series data. The state-of-the-art […]
