    Slicing embryos gently with laser light sheets.Jan Huisken - 2012 - Bioessays 34 (5):406-411.
    Light sheet microscopy is an easy to implement and extremely powerful alternative to established fluorescence imaging techniques such as laser scanning confocal, multi‐photon and spinning disk microscopy. By illuminating the sample only with a thin slice of light, photo‐bleaching is reduced to a minimum, making light sheet microscopy ideal for non‐destructive imaging of fragile samples over extended periods of time. Millimeter‐sized samples can be imaged rapidly with high resolution and high depth penetration. (...)

    Phototoxicity in live fluorescence microscopy, and how to avoid it.Jaroslav Icha, Michael Weber, Jennifer C. Waters & Caren Norden - 2017 - Bioessays 39 (8):1700003.
    Phototoxicity frequently occurs during live fluorescence microscopy, and its consequences are often underestimated. Damage to cellular macromolecules upon excitation light illumination can impair sample physiology, and even lead to sample death. In this review, we explain how phototoxicity influences live samples, and we highlight that, besides the obvious effects of phototoxicity, there are often subtler consequences of illumination that are imperceptible when only the morphology of samples is examined. Such less apparent manifestations of phototoxicity are equally problematic, and (...)

    Watching the embryo: Evolution of the microscope for the study of embryogenesis.Sharada Iyer, Sulagna Mukherjee & Megha Kumar - 2021 - Bioessays 43 (6):2000238.
    Embryos and microscopes share a long, remarkable history and biologists have always been intrigued to watch how embryos develop under the microscope. Here we discuss the advances in microscopy which have greatly influenced our current understanding of embryogenesis. We highlight the evolution of microscopes and the optical technologies that have been instrumental in studying various developmental processes. These imaging modalities provide mechanistic insights into the dynamic cellular and molecular events which drive lineage commitment and morphogenetic changes in the developing (...)

    The Body Subject: Being True to the Truths of Experience.Maxine Sheets-Johnstone - 2020 - Journal of Speculative Philosophy 34 (1):1-29.
    This essay is divided into four sections, the communal aim of which is to provide essential pathways to experiential bodily truths, thereby bringing to light the essential nature of the first-person body, the body subject. The essential pathways are anchored in Husserlian insights concerning the animate nature of the body subject. To arrive at these insights, it is necessary first to clear the field of conceptual obstacles, notably those stemming from idiosyncratic notions of proprioception that fail to accord with (...)

    Animate Realities of Gesture.Maxine Sheets-Johnstone - 2022 - Studia Phaenomenologica 22:145-165.
    Section I details Husserl’s insight into style and how a person’s individual style is played out in affect and action and in the two‑fold articulation of perception and “the kinestheses,” both of which are integral to gestural communication. Section II details how the evolutionary perspectives of Darwin and linguistic scholars complement Husserl’s insights into the animate realities of gesture and bring to light further dimensions of human and nonhuman gestural practices and possibilities through extensive experiential accounts that document the (...)

    An empirical-phenomenological critique of the social construction of infancy.Maxine Sheets-Johnstone - 1996 - Human Studies 19 (1):1-16.
    Developmental and clinical psychological findings on infancy over the past twenty years and more refute in striking ways both Piaget's and Lacan's negative characterizations of infants. Piaget's thesis is that the infant has an undifferentiated sense of self; Lacan's thesis is that the infant is no more than a fragmented piece of goods — a corps morcelé. Through an examination of recent and notable analyses of infancy by infant psychiatrist Daniel Stern, this paper highlights important features within the radically different (...)

    “As thin as a sheet of light”: Jane Addams on Narrative and End-of-Life Care.Kelly Ann Cunningham - 2023 - Transactions of the Charles S. Peirce Society 59 (1):86-104.
    Abstract:Jane Addams’ short book The Long Road of Woman’s Memory, which has largely been ignored by philosophers, identifies two important powers of memory. In addition to consoling the elderly and enabling them to make meanings of their pasts, memories also have the power to calcify into stories that reinforce shared moral values and incite moral progress. These observations serve as the starting point for a conversation on narrative medicine and its potential for improving medical treatment for patients receiving end-of-life care. (...)

  11. ABERRATION-CORRECTED ELECTRON MICROSCOPY.Thomas Vogt - 2020 - In Between Making and Knowing. pp. 513 - 525.
    Microscopy allows us to observe objects we cannot see with our eyes alone. With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, suggested that the resolution of a microscope would improve by using some yet-unknown radiation with shorter wavelengths than visible light, that is, below 390 nanometers (1 nm = 10−9 m). Electrons can (...)

    Transmission electron microscopy investigation of an ordered metastable phase in Zr-N alloys.S. Sharma, K. Moore & J. Howe - 2003 - Philosophical Magazine 83 (1):31-51.
    Supersaturated hcp f -Zr alloys containing 22-28 at.% N were prepared by nitriding sheets of Zr in an atmosphere of high-purity N 2 , followed by homogenization under high-purity Ar gas. Quenching and isothermal ageing of the alloys for various times between 500 and 650°C resulted in precipitation of a metastable phase, rather than the equilibrium phase ZrN. This investigation focused on determining the structure, orientation relationship, habit plane, morphology, growth kinetics and atomic growth mechanism of this non-equilibrium precipitate using (...)

    Lighting up gap junction channels in a flash.W. Howard Evans & Patricia E. M. Martin - 2002 - Bioessays 24 (10):876-880.
    Gap junction intercellular communication channels permit the exchange of small regulatory molecules and ions between neighbouring cells and coordinate cellular activity in diverse tissue and organ systems. These channels have short half‐lives and complex assembly and degradation pathways. Much of the recent work elucidating gap junction biogenesis has featured the use of connexins (Cx), the constituent proteins of gap junctions, tagged with reporter proteins such as Green Fluorescent Protein (GFP) and has illuminated the dynamics of channel assembly in live cells (...)

    The Frankfurt School and the authoritarian personality: Balance sheet of an insight.Geoff Boucher - 2021 - Thesis Eleven 163 (1):89-102.
    Frankfurt School critical theory is perhaps the most significant theory of society to have developed directly from a research programme focused on the critique of political authoritarianism, as it manifested during the interwar decades of the 20th century. The Frankfurt School’s analysis of the persistent roots – and therefore the perennial nature – of what it describes as the ‘authoritarian personality’ remains influential in the analysis of authoritarian populism in the contemporary world, as evidenced by several recent studies. Yet the (...)

    Puts forward an account of the printing and publishing history of the second edition of Leviathan—an edition that has the same date as the first, is known to be a later production, but has never hitherto been dated with any accuracy. With the help of bibliographical evidence and details drawn from the archives of the Stationers’ Company, a fairly detailed account of the history of this edition can be constructed. What the evidence shows is that this so‐called ‘Bear’ edition was (...)

    The main topics of this second part of a two-part essay are some consequences of the phenomenon of vacuum polarization as the most important physical manifestation of modular localization. Besides philosophically unexpected consequences, it has led to a new constructive “outside-inwards approach” in which the pointlike fields and the compactly localized operator algebras which they generate only appear from intersecting much simpler algebras localized in noncompact wedge regions whose generators have extremely mild almost free field behavior. -/- Another consequence of (...)

    New approaches for low phototoxicity imaging of living cells and tissues.Wiktoria Kasprzycka, Wiktoria Szumigraj, Przemysław Wachulak & Elżbieta Anna Trafny - 2024 - Bioessays 46 (5):2300122.
    Fluorescence microscopy is a powerful tool used in scientific and medical research, but it is inextricably linked to phototoxicity. Neglecting phototoxicity can lead to erroneous or inconclusive results. Recently, several reports have addressed this issue, but it is still underestimated by many researchers, even though it can lead to cell death. Phototoxicity can be reduced by appropriate microscopic techniques and carefully designed experiments. This review focuses on recent strategies to reduce phototoxicity in microscopic imaging of living cells and tissues. (...)

    Visualizing and quantifying cell phenotype using soft X‐ray tomography.Gerry McDermott, Douglas M. Fox, Lindsay Epperly, Modi Wetzler, Annelise E. Barron, Mark A. Le Gros & Carolyn A. Larabell - 2012 - Bioessays 34 (4):320-327.
    Soft X‐ray tomography (SXT) is an imaging technique capable of characterizing and quantifying the structural phenotype of cells. In particular, SXT is used to visualize the internal architecture of fully hydrated, intact eukaryotic and prokaryotic cells at high spatial resolution (50 nm or better). Image contrast in SXT is derived from the biochemical composition of the cell, and obtained without the need to use potentially damaging contrast‐enhancing agents, such as heavy metals. The cells are simply cryopreserved prior to imaging, and (...)

    Dorsal closure in Drosophila: cells cannot get out of the tight spot.Carl-Philipp Heisenberg - 2009 - Bioessays 31 (12):1284-1287.
    Dorsal closure (DC), the closure of a hole in the dorsal epidermis of Drosophila embryos by the joining of opposing epithelial cell sheets, has been used as a model process to study the molecular and cellular mechanisms underlying epithelial spreading and wound healing. Recent studies have provided novel insights into how different tissues function cooperatively in this process. Specifically, they demonstrate a critical function of the epidermis surrounding the hole in modulating the behavior of the amnioserosa cells inside. These findings (...)

    The Prehistoricity of Cinema: Werner Herzog's Cave of Forgotten Dreams.Daniel Spaulding - 2023 - Film-Philosophy 27 (2):282-300.
    This article argues that Werner Herzog's 2010 film Cave of Forgotten Dreams both enacts and undermines a desire for origins that was characteristic of 20th century modernist discourse. I argue that the aim of the film is literally to embody the origin of cinema, as figured in the recurring motif of projected light playing across the darkened walls of Chauvet Cave, the earliest known site of prehistoric painting. Drawing on texts by Wilson Harris, Giorgio Agamben, Jean-Luc Nancy, and Maxine (...)

    A Causal-Pluralist Metatheory of Observation.Osvaldo Pessoa - 2019 - Open Philosophy 2 (1):657-667.
    An extended definition of “observation” is developed in order to account for the usage in the physical sciences and in neuropsychology. An observation is initially defined as a perception that has a focus of attention and is guided by theoretical considerations. Since the focus may change, one adopts a pluralist position according to which the object of perception may involve any stage of the causal chain that leads to perception, such as the source of light or sound, the obstructions, (...)

    The purpose of this paper is to contribute to shed some light on the early Stoics' practice of managing platonic suggestions to construct their epistemology. Instances of such a practice, which scholars have recently focussed on, are the Stoic reassessment of the account of phantasia Plato offers in the Sophist and the image of the wax block as discussed in the Theaetetus. In this work I put forward a comparison between the simile of the soul-book, as presented by Socrates (...)

    Translocation through the nuclear pore: Kaps pave the way.Reiner Peters - 2009 - Bioessays 31 (4):466-477.
    Transport through the nuclear pore complex (NPC), a keystone of the eukaryotic building plan, is known to involve a large channel and an abundance of phenylalanine–glycine (FG) protein domains serving as binding sites for soluble nuclear transport receptors and their cargo complexes. However, the conformation of the FG domains in vivo, their arrangement in relation to the transport channel and their function(s) in transport are still vividly debated. Here, we revisit a number of representative transport models—specifically Brownian affinity gating, selective (...)

    The Exocyst: Dynamic Machine or Static Tethering Complex?Hisayo Nishida-Fukuda - 2019 - Bioessays 41 (8):1900056.
    The exocyst is a conserved octameric complex that physically tethers a vesicle to the plasma membrane, prior to membrane fusion. It is important not only for secretion and membrane delivery but also, in mammalian cells, for cytokinesis, ciliogenesis, autophagy, tumorigenesis, and host defense. The combination of genome editing and advanced light microscopy of exocyst subunits in living cells has recently shown the complex to be much more dynamic than previously appreciated, and exposed how little we still know about (...)

    The Virtue of Being Too Early: Paul A. Weiss and 'Axonal Transport'.Sabine Brauckmann - 2004 - History and Philosophy of the Life Sciences 26 (3/4):333 - 353.
    The essay introduces how Paul A. Weiss (1898-1989) analyzed his data on neuronal outgrowth and axonal transport, supported by constriction experiments of thousands of living mature nerve fibers. At the University of Chicago his group measured the steady proximo-distal flow of nerve fibers. To visualize the data he used tissue culturing, light microscopy, radioactive tracers, time-lapse motion pictures and electronmicroscopy. The work resulted in the discovery of fasciculation of outgrowing nerves and a computation of the rate of axonal (...)

It starts with a description of the early use of electron microscopy in biology, showing that electron microscopy was used as an extension of former light microscopical studies. Thus, the pictures produced by electron microscopy are interpreted as describing the micro-texture of those structures already seen in light microscopy. That was done irrespective from the specific problems of tissue preparation for electron microscopy. The (...)

    Structure suggests function: the case for synaptic ribbons as exocytotic nanomachines.David Lenzi & Henrique von Gersdorff - 2001 - Bioessays 23 (9):831-840.
    Synaptic ribbons, the organelles identified in electron micrographs of the sensory synapses involved in vision, hearing, and balance, have long been hypothesized to play an important role in regulating presynaptic function because they associate with synaptic vesicles at the active zone. Their physiology and molecular composition have, however, remained largely unknown. Recently, a series of elegant studies spurred by technical innovation have finally begun to shed light on the ultrastructure and function of ribbon synapses. Electrical capacitance measurements have provided (...)

    Unraveling docking and initiation of mRNA export through the nuclear pore complex.Mark Tingey & Weidong Yang - 2022 - Bioessays 44 (8):2200027.
    The nuclear export of mRNA through the nuclear pore complex (NPC) is a process required for the healthy functioning of human cells, making it a critical area of research. However, the geometries of mRNA and the NPC are well below the diffraction limit of light microscopy, thereby presenting significant challenges in evaluating the discrete interactions and dynamics involved in mRNA nuclear export through the native NPC.

    B Flach! B Flach!Myroslav Laiuk & Ali Kinsella - 2023 - Common Knowledge 29 (1):1-20.
    Don't tell terrible stories—everyone here has enough of their own. Everyone here has a whole bloody sack of terrible stories, and at the bottom of the sack is a hammer the narrator uses to pound you on the skull the instant you dare not believe your ears. Or to pound you when you do believe. Not long ago I saw a tomboyish girl on Khreshchatyk Street demand money of an elderly woman, threatening to bite her and infect her with syphilis. (...)

    The Greate Invention of Algebra: Thomas Harriot's Treatise on Equations.Jacqueline A. Stedall - 2003 - Oxford University Press UK.
    'The Greate Invention of Algebra' casts new light on the work of Thomas Harriot, an innovative thinker and practitioner in several branches of the mathematical sciences, including navigation, astronomy, optics, geometry, and algebra. Although on his death Harriot left behind over four thousand manuscript sheets, much of his work remains unpublished. This book focuses on one hundred and forty of Harriot's manuscript pages, those concerned with the structure and solution of equations. The original material has been carefully ordered, translated, (...)

    Trainable watershed-based model for cornea endothelial cell segmentation.Ahmed Saifullah Sami & Mohd Shafry Mohd Rahim - 2022 - Journal of Intelligent Systems 31 (1):370-392.
    Segmentation of the medical image plays a significant role when it comes to diagnosis using computer aided system. This article focuses on the human corneal endothelium’s health, which is one of the filed research interests, especially in the human cornea. Various pathological environments fasten the extermination of the endothelial cells, which in turn decreases the cell density in an abnormal manner. Dead cells worsen the hexagonal design. The mutilated endothelial cells can no longer revive back and that gives room for (...)

    How to Accommodate to the Invisible? The 'halo' of 'nano'.Vincent Karim Bontems - 2011 - NanoEthics 5 (2):175-183.
    Nanotechnologies produce many different types of images but are characterized by the ones that allow us to ‘see the atoms’ despite the fact that objects at the nanoscale are smaller than the wavelength of light and hence are ‘invisible’. Images from scanning probe microscopy (SPM), like ‘The Beginning’, have played an emblematic role in the constitution of the field and are also more likely to be used in communication outside the scientific field. These images are made, selected, modified (...)

  45. Hydrogeny.Evelina Domnitch & Dmitry Gelfand - 2011 - Continent 1 (3):156-157.
    Nature's simplest atom and mother of all matter, hydrogen feeds the stars as well as interlaces the molecules of their biological descendants – to whom it ultimately whispers the secrets of quantum reality. Hydrogen’s most prevalent earthly guise lies within the composition of water. A slight electrical disturbance can split water into hydrogen and oxygen gas, resulting in diaphanous bubble clouds slowly rising towards the liquid’s surface. Though the founding fathers of electrochemistry posited that the mass of liberated bubbles is (...)

  46. The Official Catalog of Potential Literature Selections.Ben Segal - 2011 - Continent 1 (2):136-140.
    continent. 1.2 (2011): 136-140. In early 2011, Cow Heavy Books published The Official Catalog of the Library of Potential Literature , a compendium of catalog 'blurbs' for non-existent desired or ideal texts. Along with Erinrose Mager, I edited the project, in a process that was more like curation as it mainly entailed asking a range of contemporary writers, theorists, and text-makers to send us an entry. What resulted was a creative/critical hybrid anthology, a small book in which each page opens (...)

  47. The Gravity of Pure Forces.Nico Jenkins - 2011 - Continent 1 (1):60-67.
    continent. 1.1 (2011): 60-67. At the beginning of Martin Heidegger’s lecture “Time and Being,” presented to the University of Freiburg in 1962, he cautions against, it would seem, the requirement that philosophy make sense, or be necessarily responsible (Stambaugh, 1972). At that time Heidegger's project focused on thinking as thinking and in order to elucidate his ideas he drew comparisons between his project and two paintings by Paul Klee as well with a poem by Georg Trakl. In front of Klee's (...)

    Bridging the gap between writing and cognition.Marcin Trybulec - 2013 - Pragmatics and Cognition 21 (3):469-483.
    The claim that the invention of literacy has cognitive consequences, so-called Literacy Theory, is subject to the criticism that it implies a form of technological determinism. This criticism, however, assumes an outdated Cartesian model of mind, a mind independent of the body and the external world. Such an internalistic framework leaves unexplored the cognitive consequences of the material dimension of writing. Therefore, in order to dismiss the accusations of technological determinism, the Cartesian model of mind and cognition needs to be (...)

    Hierarchy of organization in eukaryotic chromosomes (a review).Norman S. Cohn - 1971 - Acta Biotheoretica 20 (1-2):41-70.
    Several models of macromolecular arrangements in eukaryotic chromosomes have been proposed during the past fifteen years. Many of the models are consistent with physical and chemical data on the molecular components of chromosomes, and a few have the appearance of meeting the requirements for cytological organization in chromosomes. However, one of the most frustrating problems in developing a working model is to provide a scheme that fits genetic function while satisfying the structural parameters. This has not yet been achieved.Although emphasis (...)
