What are cells? How are they related to each other and to the organism as a whole? These questions have exercised biology since Schleiden and Schwann (1838–1839) first proposed cells as the key units of structure and function of all living things. But how do we try to understand them? Through new technologies like the achromatic microscope and the electron microscope. But just as importantly, through the metaphors our culture has made available to biologists in different periods and places. These two new volumes provide interesting history and philosophy of the development of cell biology. Reynolds surveys the field's changing conceptual structure by examining the varied panoply of changing metaphors used to conceptualize and explain cells – from cells as empty boxes, as building blocks, to individual organisms, to chemical factories, and through many succeeding metaphors up to one with great currency today: cells as social creatures in communication with others in their community. There is some of this approach in the Visions edited collection as well. But this collection also includes rich material on the technologies used to visualize cells and their dialectical relationship with the epistemology of the emerging distinct discipline of cell biology. This volume centres on, but is not limited to, ‘reflections inspired by [E.V.] Cowdry's [1924 volume] General Cytology’; it benefits from a conference on the Cowdry volume as well as a 2011 Marine Biological Lab/Arizona State University workshop on the history of cell biology.

So far in this volume we have considered the nature of living things and some of their key building blocks and capabilities. This has set the stage for the current section and the next where we will describe some exemplar integrated biomimetic and biohybrid systems—living machines. To place these contributions in some additional context this introduction briefly reviews the history of life and of its variety, noting some of the critical branching points in the phylogenetic tree, identifying some of the organisms that have been the focus of research on biomimetic systems, and exploring why they might be seen to be important or pivotal. We begin with the first replicators, then consider bacterial colonies, the emergence of multicellularity and of bilateral symmetry, and conclude with a brief discussion of biomimetics applied to vertebrate brain and body plans including those of humans.

Based on research literature, the article reviews the history of Hebrew popular literature since the 1930s, its connections with Yiddish Schund literature and its effects on the development of Modern Hebrew literature and Israeli identity, especially in light the New Hebrew ethos. The article features the research collection of Hebrew pulps at Arizona State Univeristy, demonstrates the significance of collecting popular materials in research libraries, and suggests possible new study directions. An appendix lists some of the materials available at the IsraPulp Collection.

For centuries, cell biology has been based on light microscopy and at the same time been limited by its optical resolution. However, several new technologies have been developed recently that bypass this limit. These new super-resolution technologies are either based on tailored illumination, nonlinear fluorophore responses, or the precise localization of single molecules. Overall, these new approaches have created unprecedented new possibilities to investigate the structure and function of cells.

As a mutually-illuminating contrast to the academic exploration in the previous article of the potential of CD-ROM as a means both of teaching a ‘classical’ playtext and of analyzing the multiple choices involved in its performance, the two following pieces explore the potential of the new technologies in the creation and documentation of live art. Focusing upon her performance Push the Boat Out, given as part of the Jezebel Season at the Institute of Contemporary Arts in 1995, Leslie Hill first outlines the thinking behind her use of the Internet and the Web – as yet more economic than CD-ROM – both for creating ‘live art’ and for rendering its conventionally ‘unprintable’ form as a ‘text’ with its own integrity. The scripted element of her performance follows. Leslie Hill is a writer and performer, currently a resident artist fellow at the Institute for Studies in the Arts, and a senior lecturer in the Theatre Department at Arizona State University. Along with Helen Paris, she is co-artistic director of the ‘curious.com’ multimedia performance company.

Present-day cellular systems biology is producing data on an unprecedented scale. This field has generated a renewed interest in the holistic, “system” character of cell structure-and-function. Underlying the data deluge, however, there is a clear and present need for a historical foundation. The origin of the “system” view of the cell dates to the birth of the protoplasm concept. The 150-year history of the role of “protoplasm” in cell biology is traced. It is found that the “protoplasmic theory,” not the “cell theory,” was the key 19th-century construct that drove the study of the structure-and-function of living cells and set the course for the development of modern cell biology. The evolution of the “protoplasm” picture into the 20th century is examined by looking at controversial issues along the way and culminating in the current views on the role of cytological organization in cellular activities. The relevance of the “protoplasmic theory” to 21st-century cellular systems biology is considered.

Research on gecko-based adhesion has become a truly interdisciplinary endeavour, encompassing many disciplines within the natural and physical sciences. Gecko adhesion occurs by the induction of van der Waals intermolecular (and possibly other) forces between substrata and integumentary filaments (setae) terminating in at least one spatulate tip. Gecko setae have increasingly been idealized as structures with uniform dimensions and a particular branching pattern. Approaches to developing synthetic simulacra have largely adopted such an idealized form as a foundational template. Observations of entire setal fields of geckos and anoles have, however, revealed extensive, predictable variation in setal form. Some filaments of these fields do not fulfil the morphological criteria that characterize setae and, problematically, recent authors have applied the term ‘seta’ to structurally simpler and likely non-adhesively competent fibrils. Herein we briefly review the history of the definition of squamate setae and propose a standardized classificatory scheme for epidermal outgrowths based on a combination of whole animal performance and morphology. Our review is by no means comprehensive of the literature regarding the form, function, and development of the adhesive setae of squamates and we do not address significant advances that have been made in many areas (e.g. cell biology of setae) that are largely tangential to their classification and identification. We contend that those who aspire to simulate the form and function of squamate setae will benefit from a fuller appreciation of the diversity of these structures, thereby assisting in the identification of features most relevant to their objectives.

The importance of this research leads to the emerging technologies of libraries. The library is one of the most important places in any academic institution and remains the primary source of information for students, teachers, and many others. The researcher aims to suggest an option for the state university and colleges in the Province of Sulu on the technological advancement in the managing library. The breakthrough of technologies can help the library in various ways. Libraries need to adopt new technology that will allow them to operate and function efficiently and effectively, increasing their productivity and improving their user services without adding personnel. The main objective is to show that an automated library system using the latest technology is more beneficial. The present scenario demands an updated technology for faster, affordable, and user-friendly in providing various library services. Fortunately, new technologies have developed Barcode, Digital libraries, Quick Response codes, and RFID systems. Consequently, applying these technologies provides an end-to-end solution for easy library operation, such as borrowing and returning books, finding and locating books, and maintaining book records. The need to develop and enhance library services to meet users' demands is necessary.
