Fast Hydrogel Micro‐Actuators Driven by Electric Fields

Advanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

Short‐term trends in great ape density in a community‐based conservation area in the eastern Democratic Republic of the Congo

Ecological Solutions and Evidence
The forests of eastern Democratic Republic of the Congo (DRC) constitute a biodiversity hotspot and provide habitat to two globally threatened great apes, the Grauer's gorilla Gorilla beringei graueri and eastern chimpanzee Pan troglodytes schweinfurthii.

Functionality in Tool Use in Western Lowland Gorillas (Gorilla gorilla gorilla) [PDF]

Animal Behavior and Cognition, 2015
Nonhuman primates are known to use objects as tools. Amongst the great apes, gorillas seem to be the least proficient tool users. Previous research has shown that the western lowland gorillas (Gorilla gorilla gorilla) at the Buffalo Zoo use buckets ...

An Autonomous Large Language Model‐Agent Framework for Transparent and Local Time Series Forecasting

Advanced Intelligent Discovery, EarlyView.
Architecture of the proposed large language model (LLM)‐based agent framework for autonomous time series forecasting in thermal power generation systems. The framework operates through a vertical pipeline initiated by natural language queries from users, which are processed by the LLM Agent Core powered by Llama.cpp and a ReAct loop with persistent ...

The Human-Fostered Gorilla Koko Shows Breath Control in Play with Wind Instruments

Biolinguistics, 2012
Breath control is critical to the production of spoken language and commonly postulated as a unique human adaptation specifically for this function. In contrast, non-human primates are often assumed to lack volitional control over their vocalizations ...

Individual distinctiveness in call types of wild western female gorillas. [PDF]

PLoS ONE, 2014
Individually distinct vocalizations play an important role in animal communication, allowing call recipients to respond differentially based on caller identity.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

The Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Visitation patterns of endangered grey parrots (Psittacus erithacus) in a forest clearing in the Democratic Republic of the Congo

Ecology and Evolution
The grey parrot (Psittacus erithacus), once abundant, has become increasingly threatened due to the combined effects of capture for the global pet trade and habitat loss. Although grey parrots are well studied in captivity, effective conservation efforts

Social Vigilance of Friends and Foes in Western Lowland Gorillas (Gorilla gorilla gorilla) [PDF]

Animal Behavior and Cognition, 2020
In social species, such as many primate species, conspecifics can pose a threat and individuals that are socially vigilant can prevent harassment. Many previous studies have focused on the role of agonistic interactions on social vigilance.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
