Awareness of the environmental issues surrounding petroleum-based materials and glass fibers has been increasing. At the same time, there is a growing interest in eco-friendly materials, such as cellulose nanofibers, which are lightweight, recyclable, biodegradable, and renewable. Therefore, more efforts have been directed towards developing cellulose nanofiber-based composites, especially for industrial use. However, replacing traditional synthetic fibers is a challenge, and extensive research is still needed in order to overcome the various drawbacks, such as high moisture absorption, poor adhesion, incompatibility, and shape irregularity.

This Collection aims to showcase the latest advances on types, sources, and processing of natural fibers, as well as the physical and mechanical properties, and high-performance applications, of natural fiber composites and cellulosic-fiber composites.

The number of people aged 60 years or over has doubled since 1980 and it is expected to double again, with projections expecting over 2 billion of such persons by 2050. The need to study and understand processes underlying aging - but also involved in many age-related conditions - has therefore never been greater. One of these processes is neuroinflammation which is known to be involved in the etiology of Alzheimer's disease, Parkinson's disease, some forms of dementia and so on. This Collection will focus on the molecular and cellular mechanisms behind this process, but also its contribution to various pathological conditions.

Understanding human development is of fundamental biological and clinical importance. Yet, the mechanisms underlying the cellular division and differentiation, that lead to the establishment and growth of a human embryo, remain elusive. Recent technological advances—such as innovations in iPSC and CRISPR technology—have enabled the development of novel three-dimensional, in vitro embryo models of unprecedented sophistication, opening up new avenues of research and promising deeper insight into the early beginnings of life. This Collection welcomes submissions investigating all aspects of early human development, including new techniques that advance our understanding of the fascinating first stages of life.

Cell death is essential for homeostasis, as it provides a means to eliminate damaged cells, which may otherwise lead to tissue damage, or tumorigenesis. The best characterized, and most evolutionarily conserved form of programmed cell death is apoptosis. Recently however, multiple other programmed cell death pathways—such as entosis, methuosis, paraptosis, ferroptosis, pyroptosis, necroptosis mitoptosis, parthanatos—have emerged. The dysregulation of these cell death programs has been implicated in diverse human pathologies, yet, much is still unknown about the mechanisms underlying these alternative pathways. In addition, non-apoptotic cell death modes may offer new opportunities to manipulate cell death in a therapeutic context. This Collection invites articles that provide insight into the molecular pathways that compose non-apoptotic cell death modalities as well as submissions outlining their roles in vivo and in disease.

The cytoskeleton exists in all cells, and comprises a highly dynamic and versatile network of filamentous proteins, that includes actin, microtubules, intermediate filaments, and septins. Through this cytoskeletal network, the cell is able to integrate various signals in order to coordinate its behavior, communicate with other cells, and adapt to its environment. The cytoskeleton is involved in virtually every cellular process, and aberrations of its component proteins are associated with many pathologies. A greater understanding of mechanisms underlying these disease etiologies will lead to new diagnostic and therapeutic applications. This Collection aims to collate research that advances our understanding of the components of the cytoskeleton and their function in human disease.

Recent developments in biophysical analytical approaches have provided greater insight into cellular macromolecule condensates, a class of membrane-less organelles. These condensates are formed by liquid-liquid phase separation (LLPS). Many biomolecules undergo LLPS, forming liquid-like condensates that mediate various physiological processes, including the acceleration of specific enzymatic reactions and the quick storage or release of biomolecules. As more studies reveal that many of the membrane-less organelles observed in cells are formed by LLPS, detailed information on how these bodies form, as well as their role in both health and disease start to emerge. This Collection is dedicated to research with a focus on LLPS, and welcomes work that approaches this topic from diverse angles, including thermodynamics, biophysics, molecular biology, cellular biology, and structural biology.

As single cell sequencing technologies started coming of age, we are increasingly better placed to probe the heterogeneity of multicellular biological system. These techniques over the last decade have shed light on developmental processes, cancer etiology, plant biology, and more. This Collection will focus on further methodological advances in the area of single cell sequencing and single cell omics, as well as on the applications of these new techniques to gain further insights into biological processes.

In February 2021, the Royal Society launched a new research initiative to foster interdisciplinary research on “animate materials,” i.e., a new class of human-made materials mimicking biology or living systems. Whilst biologically-inspired materials have long been on the rise, this emerging notion aims to combine multiple concepts in materials science (smart, self-healing, self-reporting, etc.), to identify new ways of making materials that are, at the same time, active, adaptive, and autonomous. Able to sense the environment and autonomously adapt to it to maintain their functions, these materials have the potential not only to make manufacturing and engineering more sustainable, but also to transform the concept of engineering. In the spirit of the Royal Society’s call to action, this Collection aims to facilitate interdisciplinary collaboration and gather original research focused on the development of materials with lifelike properties. Submissions that demonstrate examples of sustainable applications in the field of engineering and manufacturing are particularly welcome.
