Engineering Aging: Approaches to Model and Deconstruct Biological Complexity
Advanced Materials, EarlyView.The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

On the valves of the heart [PDF]
Abstracts of the Papers Communicated to the Royal Society of LondonThe paper contains observations upon the structure and connections of the auriculo-ventricular and arterial valves of the human heart, which the author thinks will assist in explaining their nature and functions. The relation of the “four orifices” in the base of the heart is examined, and it is shown that the aortic and left auriculo-ventricular ...

Multimodal In‐Sensor Computing with Dual‐Phase Organic Synapses for Wearable Fitness Monitoring
Advanced Materials, EarlyView.A dual‐phase organic synaptic sensor detects human respiration and ambient UV light, enabling a wearable neuromorphic system for real‐time exercise monitoring. Abstract With the advancement of wearable and mobile devices, demand for the real‐time, low‐power processing of physiological and environmental signals is growing rapidly.

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics
Advanced Materials, EarlyView.Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Advanced Materials, EarlyView.We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m
