Advanced Materials, EarlyView.Memristors offer tunable resistance and intrinsic instability, making them promising tunable noise sources. We propose a spiking‐rate‐programmable probabilistic neuron using a Ru/TaOx/Pt memristor, where resistance‐dependent noise enables frequency‐selective encoding.

The optimum fire window: applying the fire–productivity hypothesis to Jurassic climate states [PDF]
BiogeosciencesPresent-day fire frequency is related to a productivity–aridity gradient on regional and global scales. Optimum fire conditions occur at times of intermediate productivity and aridity, whereas fire is limited at the high productivity (moisture) and ...

Contemporary Fire Regimes of the Subtropical Everglades
Scientific DataAbstract Fire is a fundamental force that shapes ecosystems by influencing vegetation composition, succession, and structural diversity. Fire regimes, defined by fire frequency, intensity, and seasonality, vary across ecosystems and are critical in fire-dependent landscapes.

Advanced Materials, EarlyView.Micro‐topographical cues applied through temporally controlled microscale confinement improve the reproducibility, spatial organization, and neurosensory‐associated features of pluripotent stem cell‐derived inner ear organoids. Integration with a vascularized organoid platform further enables controlled investigation of vascular‐epithelial interactions

Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing
Advanced Materials, EarlyView.Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration
Advanced Materials, EarlyView.Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Restoring fire regimes through rewilding
Current BiologyAccelerating anthropogenic changes to climate and landscapes have degraded ecosystems globally; these include changes to naturally occurring disturbances, such as fires. Rewilding - the restoration of ecological processes to yield complex and resilient ecosystems - is a proposed strategy to maintain biodiversity in increasingly novel systems.

Advanced Materials, EarlyView.Using a bottom‐up approach, we engineered a human neuromuscular microchip to investigate distinct adaptive responses to neural stimulation and metabolic stress. Further integration of endothelial cells revealed their critical role in modulating neuromuscular excitability, establishing a comprehensive neurovascular‐muscular model.
