Control of organ size: development, regeneration, and the role of theory in biology [PDF]

open access: yesBMC Biology, 2015
How organs grow to be the right size for the animal is one of the central mysteries of biology. In a paper in BMC Biology, Khammash et al. propose a mechanism for escaping from the deficiencies of feedback control of growth as a mechanism.

Biomimetic Design of Biocompatible Neural Probes for Deep Brain Signal Monitoring and Stimulation: Super Static Interface for Immune Response‐Enhanced Contact

open access: yesAdvanced Functional Materials, EarlyView.
Ultrathin, flexible neural probes are developed with an innovative, biomimetic design incorporating brain tissue‐compatible materials. The material system employs biomolecule‐based encapsulation agents to mitigate inflammatory responses, as demonstrated through comprehensive in vitro and in vivo studies.

Temporal Dynamics and Heterogeneity of Cell Populations during Skeletal Muscle Regeneration

open access: yesiScience, 2020
Summary: Mammalian skeletal muscle possesses a unique ability to regenerate, which is primarily mediated by a population of resident muscle stem cells (MuSCs) and requires a concerted response from other supporting cell populations.

Dynamic Micromechanical Characterization of 3D Printed Bone In Vitro Models Manufactured via Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel approach to designing and fabricating high‐porosity 3D‐printed scaffolds using a customized resin. Scaffold geometry, cellular interactions, and mechanical properties are analyzed to demonstrate these engineered bone models.

Reconsidering regeneration in metazoans: an evo-devo approach

open access: yesFrontiers in Ecology and Evolution, 2015
Regeneration of body structures is an ability widely but unevenly distributed amongst the animal kingdom. Understanding regenerative biology in metazoans means understanding the multiplicity of the cellular and molecular mechanisms that lead to the ...

Topology-Aware Node Selection for Data Regeneration in Heterogeneous Distributed Storage Systems [PDF]

open access: yesarXiv, 2015
Distributed storage systems introduce redundancy to protect data from node failures. After a storage node fails, the lost data should be regenerated at a replacement storage node as soon as possible to maintain the same level of redundancy. Minimizing such a regeneration time is critical to the reliability of distributed storage systems.

Material Composition Gradient Controls the Autonomous Opening of Banksia Seed Pods in Fire‐Prone Habitats

open access: yesAdvanced Functional Materials, EarlyView.
The seed pod valves of Australian Banksia attenuata plants are not simply bi‐layers which bend when dry. These experiments and models reveal complex mechanics, which allow seed release only after several steps of seed pod opening. Stiffness gradients prevent delamination of the valves during loading, and a shape‐memory function protects the seeds ...
