Three‐Dimensional Hierarchical Nanowire‐Networks with Deep‐Focus Tolerance and Adhesion Robustness for Harsh‐Environment SERS Sensing

Advanced Functional Materials, EarlyView.
A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

Advanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

A reference genome for the Harpy Eagle reveals steady demographic decline and chromosomal rearrangements in the origin of Accipitriformes

Scientific Reports
The Harpy Eagle (Harpia harpyja) is an iconic species that inhabits forested landscapes in Neotropical regions, with decreasing population trends mainly due to habitat loss, and currently classified as vulnerable.

Gourd‐Inspired Design of Unit Cell with Multiple Gradients for Physiological‐Range Pressure Sensing

Advanced Functional Materials, EarlyView.
Gourd‐shaped micro‐dome arrays with coordinated modulus, conductivity, and geometric gradients co‐optimize sensitivity and linearity in piezoresistive tactile sensors. Under pressure, a solid upper dome embeds into a porous lower dome, triggering rapid contact‐area growth and series‐to‐parallel conduction, enabling unsaturated, intensity‐resolved ...
