Removal of old nest material decreases reuse of artificial burrows by burrowing owls

open access: yesWildlife Society Bulletin, 2015
Artificial burrows are considered an important management and conservation tool for burrowing owls (Athene cunicularia). This species regularly adorns natural and artificial burrows with mammal dung and other materials, which remain between years so that

Has the Australian Endemic Grey Falcon the Most Extreme Dietary Specialization among all Falco Species?

open access: yesAnimals, 2022
A clear understanding of a species’ diet is crucial in understanding its spatio-temporal dynamics, and is, therefore, pertinent to conservation considerations.

CTNS mutations in publicly-available human cystinosis cell lines

open access: yesMolecular Genetics and Metabolism Reports, 2015
Patient samples play an important role in the study of inherited metabolic disorders. Open-access biorepositories distribute such samples. Unfortunately, not all clinically-characterized samples come with reliable genotype information.

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

open access: yesAdvanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Nest box use by American Kestrels and other cavity-nesting birds during the nonbreeding season

open access: yesAvian Conservation and Ecology, 2017
Nest boxes are posted to provide breeding sites for cavity-nesting birds but less is known about their function in the nonbreeding season, when nest boxes may become important roost sites.

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

BLOC1S1 Attenuates B. Melitensis 16M LPS‐Triggered Autophagy by Spatial Confinement of TDP‐43

open access: yesAdvanced Science, EarlyView.
This study explores how B. melitensis 16M LPS and BLOC1S1 regulate autophagy in goat spermatogonial stem cells. The 16M LPS is activating AMPK‐dependent autophagy, increasing LC3B‐II/I ratios and lysosomal genes, while Escherichia coli LPS shows no effect.

A study of the correlation between the serum Latexin levels and the mTORC subunits Raptor and Rictor in the molecular pathogenesis of chronic lymphocytic leukemia

open access: yesMedicine Science, 2021
Hematopoietic stem cells (HSCs) ensure the lifelong production of blood cells throughout a lifetime. Latexin (Lxn) is thought to have a tumor suppressor role and endogenously down-regulate the number of HSCs via increased apoptosis.

Muscle Organoids Reveal Exercise‐Like Contractions Rapidly Promote Muscle Health Via Lamtor1's Signaling to Both AMPK and mTOR

open access: yesAdvanced Science, EarlyView.
This study develops a novel 3D human skeletal muscle organoid platform to study the immediate molecular effects of exercise‐like contractions. The model uncovers rapid proteomic and transcriptomic responses, resolving a fundamental paradox by demonstrating how exercise‐induced Lamtor1 coordinately activates both AMPK and mTORC1. Lamtor1 is a compelling

Critically assessing the utility of portable lead analyzers for wildlife conservation

open access: yesWildlife Society Bulletin, 2018
Lead (Pb) exposure in wildlife is a widespread management and conservation concern. Quantitative determination of Pb concentrations in wildlife tissues is the foundation for estimating exposure and risk.
