Jointless Tongue‐Like Bioactuator for Multidirectional Motion Through Directional Electrical Stimulation

open access: yesAdvanced Intelligent Systems, EarlyView.
A tongue‐like bioactuator is developed using orthogonally aligned cultured skeletal muscle tissues. By applying directional electrical stimulation of varying strengths, the actuator achieves jointless, multidirectional movements. The device features a fully soft, skeleton‐free design, enabling biomimetic deformation and functional actuation, and offers

Human‐driven habitat conversion is a more immediate threat to Amboseli elephants than climate change

open access: yesConservation Science and Practice, 2019
Global ecosystem change presents a major challenge to biodiversity conservation, which must identify and prioritize the most critical threats to species persistence given limited available funding.

Gene losses did not stop the evolution of big brains

open access: yeseLife, 2018
Elephants and fruit bats have evolved large brains even though they have lost a gene that is fundamental to the supply of energy to the brain when glucose is not available.

Is nonlinear propagation responsible for the brassiness of elephant trumpet calls? [PDF]

open access: yes, 2014
African elephants (Loxodonta africana) produce a broad diversity of sounds ranging from infrasonic rumbles to much higher frequency trumpets. Trumpet calls are very loud voiced signals given by highly aroused elephants, and appear to be produced by a ...

Programmable‐Stiffness Tensegrity Continuum Robot for Adaptive Multicurvature On‐Orbit Assembly

open access: yesAdvanced Intelligent Systems, EarlyView.
A bioinspired tensegrity‐based continuum robot (BTCR) with programmable stiffness enables adaptive multicurvature morphing via coordinated intra‐ and intermodule regulation. A unified energy‐based framework predicts self‐equilibrium and deformation for serial modules. Experiments and Simulations demonstrate reconfiguration into hexagonal, circular, and

Comparative cross-sectional survey on gastrointestinal parasites of captive, semi-captive, and wild Elephants of Sri Lanka

open access: yesJournal of Threatened Taxa, 2018
Parasites can influence the fitness of individuals particularly of small populations of endangered species.  An island-wide, cross sectional, coprological survey was carried out from 03 January to 30 October 2015, to determine the gastrointestinal (GI ...

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Measuring human–wildlife conflicts: Comparing insights from different monitoring approaches

open access: yesWildlife Society Bulletin, 2017
Studies investigating wildlife crop‐damage have been widely documented, but methods often vary and results can be difficult to compare across national and international regions.
