Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Advanced Sensor Research, EarlyView.Sports‐related traumatic brain injuries (TBIs) remain underdiagnosed, within amateur athletic cohorts. This review critically synthesises recent advancements in AI‐assisted neuroimaging, blood‐based biomarker profiling, wearable biosensing platforms for early detection, injury stratification, and longitudinal surveillance of TBIs.

A Skin‐Adherent Magneto‐Inertial Wearable for Real‐Time Joint Motion Analysis
Advanced Sensor Research, EarlyView.An imperceptible magneto‐inertial wearable couples a skin‐adherent PDMS‐NdFeB patch with a 9‐DoF IMU to track joint kinematics in real time and classify range‐of‐motion (Limited/Normal/Hypermobile) via a 1D‐CNN (95.3% accuracy). Wireless BLE streaming and a mobile app enable feedback.

Electrochemical Deoxygenation Electrolyzers Using an Organic Catalyst
Advanced Sustainable Systems, EarlyView.Conductive polymers offer a promising metal‐free route for the oxygen reduction reaction (ORR) in deoxygenation electrolyzers. The n‐type polymer demonstrates that BBL catalyzes ORR via a four‐electron pathway with high mass activity. A low‐voltage electrolyzer using BBL‐coated electrodes and catechol as a compensating redox additive efficiently ...

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice
Advanced Science, EarlyView.Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide
