Large, long range tensile forces drive convergence during [PDF]

open access: yes, 2018
Indirect evidence suggests that blastopore closure during gastrulation of anamniotes, including amphibians such as Xenopus laevis, depends on circumblastoporal convergence forces generated by the marginal zone (MZ), but direct evidence is lacking.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Water‐Efficient Smart Drip Irrigation Enabled by a Low‐Power and High‐Efficiency Flexible Electromagnetic Actuator

open access: yesAdvanced Science, EarlyView.
Water scarcity poses a critical threat to global food security. A low‐power, flexible electromagnetic actuator is presented for smart drip irrigation systems. The device achieves precise, wide‐range flow modulation (0.05–5.8 mL/min) in response to real‐time plant demands, reducing water consumption compared to conventional flood irrigation.
