Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics

open access: yesAdvanced Science, EarlyView.
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

open access: yesAdvanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

Bioinspired Hierarchical Architecture with Water Transport Channels for Strong Adhesion at the Sweating Interface

open access: yesAdvanced Science, EarlyView.
To address adhesion failure in sweaty epidermal electronics, this study proposes a cross‐species, multi‐scale biomimetic interface. By modeling staged wet adhesion, it integrates self‐regulating liquid bridges with directional drainage. This design ensures stable, high‐performance flexible sensing in complex physiological environments, offering a ...
