Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

North China Plain threatened by deadly heatwaves due to climate change and irrigation

open access: yesNature Communications, 2018
North China Plain is the heartland of modern China. This fertile plain has experienced vast expansion of irrigated agriculture which cools surface temperature and moistens surface air, but boosts integrated measures of temperature and humidity, and hence

Astrocyte Enrichment of 3D Cortical Constructs Enhances Brain Repair

open access: yesAdvanced Science, EarlyView.
This study highlights the role of astrocytes in supporting neural progenitor cell survival and differentiation after traumatic brain injury. Astrocytes enhanced neuronal differentiation, improved cell survival in co‐cultures, and promoted integration of microfluidics‐based implants with host tissue following implantation. Additionally, increased axonal

A reinforcement learning approach to irrigation decision-making for rice using weather forecasts

open access: yes, 2021
Improving efficiency with the use of rainfall is one of the effective ways to conserve water in agriculture. At present, weather forecasting can be used to potentially conserve irrigation water, but the risks of unnecessary irrigation and the yield loss ...

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.

Deciphering and Targeting the Schwannoma‐Neuron‐Macrophage Crosstalk for the Treatment of Schwannomatosis and Associated Pain

open access: yesAdvanced Science, EarlyView.
We established patient‐derived SWN cell lines and orthotopic PDX models that recapitulate patient pain phenotypes, alongside a novel intravital DRG imaging platform to track macrophage infiltration and neuronal pain responses. Using these models, we define HMGB1–CCL2–IL‐6 signaling crosstalk driving pain and identify EGF signaling as a key regulator of
