This study developed keratin-based hydrogels with improved water solubility and tunable properties, demonstrating excellent cytocompatibility, suggesting potential for biomedical applications.

This study introduces a new multiaxial bioreactor system that uniformly stretches tissue-engineered skin grafts and improves skin tissue maturation through enhanced cellular distribution and environmental monitoring.

In this study, researchers used atomic force microscopy to evaluate mechanical stiffness across different skin layers in six participants, finding the highest stiffness in the epidermis and lower stiffness as layers progress to subcutaneous tissue, enhancing understanding of skin's physical properties and aiding future research.

This study used multi-omics analysis to explore how wheat roots adapt to temperature stress, revealing that distinct hormonal signaling pathways are linked to iron homeostasis and drive root morphological changes, supporting the idea of an 'iron-dependent hormonal trade-off' model.

This study reports a method for fabricating biofunctional polymer fibers by using DNA-programmable cell-free protein synthesis integrated through solution blow spinning, enabling in situ protein production and potential applications in respirators, sampling swabs, and other advanced materials.

This study found that depleting fibroblasts in the skin does not affect the proliferative capacity of epidermal stem cells at various ages, suggesting robust compensatory mechanisms maintain skin functionality despite these cellular changes.

This study developed a model showing that keratin elasticity in skin may be influenced by electrostatic and bridging interactions between keratin filaments, contingent on the balance of charges in the surrounding medium.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.
