Culture-independent high-throughput sequencing has provided unprecedented insights into microbial ecology, particularly for Earth’s most ubiquitous and diverse inhabitants – the viruses. A plethora of methods now exist for amplifying the vanishingly small amounts of nucleic acids in natural viral communities in order to sequence them, and sequencing depth is now so great that viral genomes can be detected and assembled even amid large concentrations of non-viral DNA. Complementing these advances in amplification and sequencing is the ability to (...) physically link fluorescently labeled viruses to their host cells via high-throughput flow sorting. Sequencing of such isolated virus–host pairs facilitates cultivation-independent exploration of the natural host range of viruses. Within the next decade, as these technologies become widespread, we can expect to see a systematic expansion of our knowledge of viruses and their hosts. (shrink)

Throughout evolution, there has been interaction and exchange between RNA pools in the environment, and DNA and RNA pools of eukaryotic organisms. Metagenomic and metatranscriptomic sequencing of invertebrate hosts and their microbiota has revealed a rich evolutionary history of RNA virus shuttling between species. Horizontal transfer adapted the RNA pool for successful future interactions which lead to zoonotic transmission and detrimental RNA viral pandemics like SARS‐CoV2. In eukaryotes, noncoding RNA (ncRNA) is an established mechanism derived from prokaryotes to defend (...) against viral attack through innate immunity and regulation of host‐derived mRNA. Transgenerational inheritance of ncRNA is evidence for feedforward adaptive immunity and epigenetically encoded environmental change across generations, which may explain the ‘‘missing heritability’’ of common disease. Causal graph theory and the Price Equation can model epigenetic inheritance involving dynamic internal and external RNA pools. Experimental designs should include metatranscriptomic analyses to understand how ncRNA responds to rapidly changing environmental conditions, within and between organisms, and across generations.

ABSTRACT Why did the popping of the housing bubble bring the financial system—rather than just the housing sector of the economy—to its knees? The answer lies in two methods by which banks had evaded regulatory capital requirements. First, they had temporarily placed assets—such as securitized mortgages—in off‐balance‐sheet entities, so that they did not have to hold significant capital buffers against them. Second, the capital regulations also allowed banks to reduce the amount of capital they held against assets that remained on (...) their balance sheets—if those assets took the form of AAA‐rated tranches of securitized mortgages. Thus, by repackaging mortgages into mortgage‐backed securities, whether held on or off their balance sheets, banks reduced the amount of capital required against their loans, increasing their ability to make loans many‐fold. The principal effect of this regulatory arbitrage, however, was to concentrate the risk of mortgage defaults in the banks and render them insolvent when the housing bubble popped. (shrink)

Charles Eisenmann, dans un compte-rendu critique de la Pensée juridique, publié dans la Revue de droit public en 1961, écrivait : " On voudrait proclamer d'abord sans réserves, les rares qualités de l'ouvrage, qui en rendent la lecture très recommandable, en particulier pour ceux qui, jeunes ou juristes déjà formés, n'ont pas encore ou n'ont plus commerce très assidu avec la théorie ou la philosophie du droit. Ils prendront contact avec une pensée vivante et chaude, qui cherche avec ardeur, souplesse (...) et agilité." Les qualités qui ont conduit la Pensée juridique à être un des ouvrages de base de la formation théorique de toute une génération de juristes, celle des décennies 60-70, demeurent encore aujourd'hui intactes. C'est pourquoi il nous a paru souhaitable d'ouvrir la nouvelle collection des introuvables des éditions Panthéon- Assas par une réédition de l'ouvrage de Michel Virally. (shrink)

We show how metagenomic analysis of the human gut antibiotic resistome, compared across large populations and against environmental or agricultural resistomes, suggests a strong anthropogenic cause behind increasing antibiotic resistance in bacteria. This area has been the subject of intense and polarized debate driven by economic and political concerns; therefore such recently available insights address an important need. We derive and compare antibiotic resistomes of human gut microbes from 832 individuals from ten different countries. We observe and describe significant differences (...) between samples from these countries in the gut resistance potential, in line with expectations from antibiotic usage and exposure in medical and food production contexts. Our results imply roles for both of these sources in increased resistance among pathogens in recent history. In contrast, other available metadata such as age, body mass index, sex, or health status have little effect on the antibiotic resistance potential of human gut microbes.Also watch the Video Abstract.

Metagenomics is an emerging microbial systems science that is based on the large-scale analysis of the DNA of microbial communities in their natural environments. Studies of metagenomes are revealing the vast scope of biodiversity in a wide range of environments, as well as new functional capacities of individual cells and communities, and the complex evolutionary relationships between them. Our examination of this science focuses on the ontological implications of these studies of metagenomes and metaorganisms, and what they mean for (...) common sense and philosophical understandings of multicellularity, individuality and organism. We show how metagenomics requires us to think in different ways about what human beings are and what their relation to the microbial world is. Metagenomics could also transform the way in which evolutionary processes are understood, with the most basic relationship between cells from both similar and different organisms being far more cooperative and less antagonistic than is widely assumed. In addition to raising fundamental questions about biological ontology, metagenomics generates possibilities for powerful technologies addressed to issues of climate, health and conservation. We conclude with reflections about process-oriented versus entity-oriented analysis in light of current trends towards systems approaches. (shrink)

Microbial genome sequencing has entered a new phase, where DNA sequence information is gathered from entire microbial communities (metagenomics or environmental genomics) rather than from individual microorganisms. By providing access to the genetic material of vast numbers of organisms, most of which are organisms that have never been isolated or cultivated, a new level of insight is being gained into the diversity and extent of the microbial processes that are presently occuring in environmental communities. By extending metagenomic‐based approaches to (...) the study of very complex and methodologically recalcitrant soil environments, a recent study has found that ammonia‐oxidizing archaea are more abundant in many soils than bacteria.1 These findings not only highlight the undoubtedly critical yet unknown roles that archaea play in global nutrient cycles but illustrate the importance of genomic studies for informing us about the functional capacity of life on Earth.

As the international genomic research community moves from the tool-making efforts of the Human Genome Project into biomedical applications of those tools, new metaphors are being suggested as useful to understanding how our genes work - and for understanding who we are as biological organisms. In this essay we focus on the Human Microbiome Project as one such translational initiative. The HMP is a new 'metagenomic' research effort to sequence the genomes of human microbiological flora, in order to pursue the (...) interesting hypothesis that our 'microbiome' plays a vital and interactive role with our human genome in normal human physiology. Rather than describing the human genome as the 'blueprint' for human nature, the promoters of the HMP stress the ways in which our primate lineage DNA is interdependent with the genomes of our microbiological flora. They argue that the human body should be understood as an ecosystem with multiple ecological niches and habitats in which a variety of cellular species collaborate and compete, and that human beings should be understood as 'superorganisms' that incorporate multiple symbiotic cell species into a single individual with very blurry boundaries. These metaphors carry interesting philosophical messages, but their inspiration is not entirely ideological. Instead, part of their cachet within genome science stems from the ways in which they are rooted in genomic research techniques, in what philosophers of science have called a 'tools-to-theory' heuristic. Their emergence within genome science illustrates the complexity of conceptual change in translational research, by showing how it reflects both aspirational and methodological influences. (shrink)

Metagenomics is a culture‐ and PCR‐independent approach that is now widely exploited for directly studying microbial evolution, microbial ecology, and developing biotechnologies. Observations and discoveries are critically dependent on DNA extraction methods, sequencing technologies, and bioinformatics tools. The potential pitfalls need to be understood and, to some degree, mastered if the resulting data are to survive scrutiny. In particular, methodological variations appear to affect results from different ecosystems differently, thus increasing the risk of biological and ecological misinterpretation. Part of (...) the difficulty is derived from the lack of knowledge concerning the true microbial diversity and because no approach can guarantee accessing microorganisms in the same proportion in which they exist in the environment. However, the variation between different approaches (e.g. DNA extraction techniques, sequence annotation systems) can be used to evaluate whether observations are meaningful. These methodological variations can be integrated into the error analysis before comparing microbial communities. (shrink)

Background: Microbiome biomarker discovery for patient diagnosis, prognosis, and risk evaluation is attracting broad interest. Selected groups of microbial features provide signatures that characterize host disease states such as cancer or cardio-metabolic diseases. Yet, the current predictive models stemming from machine learning still behave as black boxes and seldom generalize well. Their interpretation is challenging for physicians and biologists, which makes them difficult to trust and use routinely in the physician-patient decision-making process. Novel methods that provide interpretability and biological insight (...) are needed. Here, we introduce "predomics", an original machine learning approach inspired by microbial ecosystem interactions that is tailored for metagenomics data. It discovers accurate predictive signatures and provides unprecedented interpretability. The decision provided by the predictive model is based on a simple, yet powerful score computed by adding, subtracting, or dividing cumulative abundance of microbiome measurements. -/- Results: Tested on >100 datasets, we demonstrate that predomics models are simple and highly interpretable. Even with such simplicity, they are at least as accurate as state-of-the-art methods. The family of best models, discovered during the learning process, offers the ability to distil biological information and to decipher the predictability signatures of the studied condition. In a proof-of-concept experiment, we successfully predicted body corpulence and metabolic improvement after bariatric surgery using pre-surgery microbiome data. -/- Conclusions: Predomics is a new algorithm that helps in providing reliable and trustworthy diagnostic decisions in the microbiome field. Predomics is in accord with societal and legal requirements that plead for an explainable artificial intelligence approach in the medical field. (shrink)

Exploratory experimentation and high-throughput molecular biology appear to have considerable affinity for each other. Included in the latter category is metagenomics, which is the DNA-based study of diverse microbial communities from a vast range of non-laboratory environments. Metagenomics has already made numerous discoveries and these have led to reinterpretations of fundamental concepts of microbial organization, evolution, and ecology. The most outstanding success story of metagenomics to date involves the discovery of a rhodopsin gene, named proteorhodopsin, in marine (...) bacteria that were never suspected to have any photobiological capacities. A discussion of this finding and its detailed investigation illuminates the relationship between exploratory experimentation and metagenomics. Specifically, the proteorhodopsin story indicates that a dichotomous interpretation of theory-driven and exploratory experimentation is insufficient and that an interactive understanding of these two types of experimentation can be usefully supplemented by another category, "natural history experimentation". Further reflection on the context of metagenomics suggests the necessity of thinking more historically about exploratory and other forms of experimentation. (shrink)

Viral modernity is a concept based upon the nature of viruses, the ancient and critical role they play in evolution and culture, and the basic application to understanding the role of information and forms of bioinformation in the social world. The concept draws a close association between viral biology on the one hand, and information science on the other – it is an illustration and prime example of bioinformationalism that brings together two of the most powerful forces that (...) now drive cultural evolution. The concept of viral modernity applies to viral technologies, codes and ecosystems in information, publishing, education and emerging knowledge systems. This paper traces the relationship between epidemics, quarantine, and public health management and outlines elements of viral-digital philosophy based on the fusion of living and technological systems. We discuss Covid-19 as a ‘bioinformationalist’ response that represents historically unprecedented level of sharing information from the sequencing of the genome to testing for a vaccination. Finally, we look at the US response to Covid-19 through the lens of infodemics and post-truth. The paper is followed by three open reviews, which further refine its conclusions as they relate to philosophy and the notion of the virus as Pharmakon. (shrink)

This paper addresses global bioethical challenges entailed in emerging viral diseases, focussing on their socio-cultural dimension and seeing them as symptomatic of the current era of globalisation. Emerging viral threats exemplify the extent to which humans evolved into a global species, with a pervasive and irreversible impact on the planetary ecosystem. To effectively address these disruptive threats, an attitude of preparedness seems called for, not only on the viroscientific, but also on bioethical, regulatory and governance levels. This paper (...) analyses the global bioethical challenges of emerging viral threats from a dialectical materialist (Marxist) perspective, focussing on three collisions: (1) the collision of expanding networks of globalisation with local husbandry practices; (2) the collision of global networks of mobility with disrupted ecosystems; and (3) the collision of viroscience as a globalised research field with existing regulatory frameworks. These collisions emerge in a force field defined by the simultaneity of the non-simultaneous. Evidence-based health policies invoke discontent as they reflect the normative logic of a globalised knowledge regime. The development of a global bioethics or macro-ethics requires us to envision these collisions not primarily as issues of benefits and risks, but first and foremost as normative tensions closely entangled with broader socio-economic and socio-cultural developments.

In late March of 2020, a new hashtag, #FilmYourHospital, made its first appearance on social media. The hashtag encouraged people to visit local hospitals to take pictures and videos of empty hospitals to help “prove” that the COVID-19 pandemic is an elaborate hoax. Using techniques from Social Network Analysis, this case study examines how this conspiracy theory propagated on Twitter and whether the hashtag virality was aided by the use of automation or coordination among Twitter users. We found that while (...) much of the content came from users with limited reach, the oxygen that fueled this conspiracy in its early days came from a handful of prominent conservative politicians and far right political activists on Twitter. These power users used this hashtag to build awareness about the campaign and to encourage their followers to break quarantine and film what is happening at their local hospitals. After the initial boost by a few prominent accounts, the campaign was mostly sustained by pro-Trump accounts, followed by a secondary wave of propagation outside the U.S. The rise of the #FilmYourHospital conspiracy from a single tweet demonstrates the ongoing challenge of addressing false, viral information during the COVID-19 pandemic. While the spread of misinformation can be potentially mitigated by fact-checking and directing people to credible sources of information from public health agencies, false and misleading claims that are driven by politics and supported by strong convictions and not science are much harder to root out.

In this thought-provoking work, Tony D. Sampson presents a contagion theory fit for the age of networks. Unlike memes and microbial contagions, _Virality_ does not restrict itself to biological analogies and medical metaphors. It instead points toward a theory of contagious assemblages, events, and affects. For Sampson, contagion is not necessarily a positive or negative force of encounter; it is how society comes together and relates. Sampson argues that a biological knowledge of contagion has been universally distributed by way of (...) the rhetoric of fear used in the antivirus industry and other popular discourses surrounding network culture. This awareness is also detectable in concerns over _too much connectivity_, such as problems of global financial crisis and terrorism. Sampson’s “virality” is as established as that of the biological meme and microbe but is not understood through representational thinking expressed in metaphors and analogies. Rather, Sampson interprets contagion theory through the social relationalities first established in Gabriel Tarde’s microsociology and subsequently recognized in Gilles Deleuze’s ontological worldview. According to Sampson, the reliance on representational thinking to explain the social behavior of networking—including that engaged in by nonhumans such as computers—allows language to overcategorize and limit analysis by imposing identities, oppositions, and resemblances on contagious phenomena. It is the power of these categories that impinges on social and cultural domains. Assemblage theory, on the other hand, is all about relationality and encounter, helping us to understand the viral as a positively sociological event, building from the molecular outward, long before it becomes biological.

Viruses are major drivers of global biogeochemistry and the etiological agents of many diseases. They are also the winners in the game of life: there are more viruses on the planet than cellular organisms and they encode most of the genetic diversity on the planet. In fact, it is reasonable to view life as a viral incubator. Nevertheless, most ecological and evolutionary theories were developed, and continue to be developed, without considering the virosphere. This means these theories need to (...) be to reinterpreted in light of viral knowledge or we need to develop new theory from the viral point-of-view. Here we briefly introduce our viral planet and then address a major outstanding question in biology: why is most of life viral? A key insight is that during an infection cycle the original virus is completely broken down and only the associated information is passed on to the next generation. This is different for cellular organisms, which must pass on some physical part of themselves from generation to generation. Based on this premise, it is proposed that the thermodynamic consequences of physical information (e.g., Landauer’s principle) are observed in natural viral populations. This link between physical and genetic information is then used to develop the Viral Information Hypothesis, which states that genetic information replicates itself to the detriment of system energy efficiency (i.e., is viral in nature). Finally, we show how viral information can be tested, and illustrate how this novel view can explain existing ecological and evolutionary theories from more fundamental principles. (shrink)

The global response to managing the spread of HIV has recently undergone a significant shift with the advent of ‘treatment as prevention’, a strategy which presumes that scaling-up testing and treatment for people living with HIV will produce a broader preventative benefit. Treatment as prevention includes an array of diagnostic, technological and policy developments that are creating new understandings of how HIV circulates in bodies and spaces. Drawing on the work of Michel Foucault, we contextualize these developments by linking them (...) to systems of governance and discursive subjectivation. The goal of this article is to problematize the growing importance of viral suppression in the management of HIV and the use of related surveillance technologies. For people living with HIV, we demonstrate how treatment-as-prevention’s emphasis on individual and collective viral load is transforming the performative dimensions of embodied risk, affect, subjectivity and sex.

We are experiencing a historical moment characterized by unprecedented conditions of virality: a viral pandemic, the viral diffusion of misinformation and conspiracy theories, the viral momentum of ongoing Hong Kong protests, and the viral spread of #BlackLivesMatter demonstrations and related efforts to defund policing. These co-articulations of crises, traumas, and virality both implicate and are implicated by big data practices occurring in a present that is pervasively mediated by data materialities, deeply rooted dataist ideologies that entrench (...) processes of datafication as granting objective access to truth and attendant practices of tracking, data analytics, algorithmic prediction, and data-driven targeting of individuals and communities. This collection of papers explores how data is figuring in the making of the discourses, lived realities, and systemic inequalities of the uneven impacts of the coronavirus pandemic. (shrink)

Cancer cells exploit mechanisms to evade immune detection triggered by aberrant self‐nucleic acids (NA). PARP7, a key player in this immune evasion strategy, has emerged as a potential target for cancer therapy. PARP7 inhibitors reactivate NA sensing, resulting in type I interferon (IFN) signaling, programmed cell death, anti‐tumor immunity, and tumor regression. Cancer cells with elevated IFN‐stimulated gene (ISG) scores, representing a viral mimicry‐primed state, are particularly sensitive to PARP7 inhibition. This review focuses on the endogenous sources of NA (...) in cancer and the potential to exploit elevated aberrant self‐NA in cancer therapy. We describe strategies to increase cytoplamic NA levels, including targeting epigenetic control, DNA damage response, and mitochondrial function. We also discuss targeting RNA processing pathways, such as splicing and RNA editing, to enhance the immunostimulatory potential of existing NA. Combining PARP7 inhibitors with NA elevating strategies may improve cancer immunotherapy, especially for tumors with high ISG scores. (shrink)

This chapter argues that the human, all too human vulnerability to mimesis (imitation) is a central and so far underdiagnosed element internal to the Covid-19 pandemic crisis. Supplementing medical accounts of viral contagion, the chapter develops a genealogy of the concept of mimesis – from antiquity to modernity to the present – that is attentive to both its pathological and therapeutic properties. If an awareness of the pathological side of mimetic contagion is constitutive of the origins of philosophy, in (...) Plato’s Republic, and crowd psychology called attention to the mirroring dynamic of affective contagion among crowds and publics in the modern period, the Covid-19 pandemic crisis highlights the pathological implications of hypermimetic conspiracies reloaded by new media, while also revealing the human ability to develop therapeutic patho-logies – that is, critical discourses (or logoi), on the contagious dynamic of mimetic pathos. Like a Janus-faced mirror, then, this genealogy of homo mimeticus calls attention to both the contemporary dangers of affective contagion and to the urgency of transformations or metamorphosis to counter future pandemic and environmental threats that loom large in the Anthropocene.

Controversial taboo appeals as an executional cue in viral advertising have commonly been used by advertisers. In this context, the study investigates the role of medium context on the effectiveness of controversial taboo ads. By implementing a tightly controlled experiment which deals with controversial taboo ads embedded in a press article and in a viral context, the study finds that the viral medium context does not lead to a more positive attitude toward the embedded brand or to (...) more positive purchase intentions. In addition, a viral medium context triggers ‘unintended consequences’ that lead consumers to undermine the level of tabooness of the viral advertising and subjective norms. To increase the external validity of the research, the results were replicated for two kinds of controversial taboo appeals; one related to sexuality, and the other to death. The results provide useful implications for theory and practice. Extending viral advertising research, a different angle on controversial viral advertising has been taken, shifting from an advertiser and brand focus, to a societal and social one. The work leads to a better understanding of the ethics of controversial viral advertising, and demonstrates its role in the trivialization of taboo behaviors and imagery. The results confirm the need for more regulation of online buzz communication and encourage regulatory bodies to extend policies of viral advertising regulation. (shrink)

As companies increasingly communicate CSR initiatives through social media, viral message propagation has become a crucial prerequisite for CSR success. Evidence from two experimental studies, one based on a national representative online sample, shows that social media peers’ endorsement of a CSR message in terms of number of shares, likes and positive replies contributes to an individual’s intention to share it on the social network and thereby participate in message propagation, and that this process can be explained by normative (...) influences exerted by the social media community through the activation of injunctive and descriptive norms, as well as social identity motives. Findings further confirmed that the norm-activating effects of social media endorsement are moderated by the empowering qualities of the CSR message, the sharing source of the message by affecting CSR credibility, and the recipient’s interdependent self-construal. Corporate communication managers are advised to achieve a high degree of initial social media endorsement of their CSR message, for recipients of the message to perceive social pressure motivating message sharing with their social media peers.

Stereotypes about exotic peoples and animals of the Orient shaped popular origin stories about COVID-19 in media reports. Outbreak narratives centred on the seafood market in Wuhan began to fall apart as new evidence was published by medical doctors, virologists, and epidemiologists. No viruses in bats or pangolins have been found that are direct ancestors of SARS-CoV2, the virus responsible for COVID-19 symptoms. Viruses are also being transformed as they interact with the human institutions, infrastructures and behaviours that facilitate their (...) spread. Epidemiological growth curves are shaped by national and foreign capital, cosmopolitanism, aspirations for independence and ongoing interdependence, the discourse of power and the discourse of resistance, as well as coexistence and violence. In reckoning with SARS-CoV2, we need to anticipate disruptive surprise of viral emergence rather recursively search for origins. Departing from Foucault’s foundational insights, this article gestures towards genealogies of possible viral futures. (shrink)

What is viral law? In order to being my discussion, I note that the last two years have been extremely difficult to understand and that we, meaning those who have lived through the pandemic, have struggled to make sense. Thus, I make the argument that the virus has impacted upon not only the individual’s ability to make sense in a world where every day routines have been upended, but also social and political structures that similarly rely on repetition to (...) continue to function. According to this thesis, Covid-19 is more than simply a biological organism, but also a cultural virus that undermines the organisation of social, political, and economic systems and requires new ways of thinking about how we might move forward into a post-Covid world. In the name of beginning this project of making sense of Covid-19, I track back in history to the comparable reference point of the Spanish flu pandemic of 1918–1920 and, in particular, a reading of Freud’s Beyond the Pleasure Principle, which the founder of psychoanalysis wrote in the shadow of the virus. In reading Freud’s attempt to write a psychology of death in the context of this funereal period of history, I argue that he set out first, a mythological theory of viral law concerned with the death drive, before turning to second, a techno-scientific, biological theory of the same law characterised by microbial immortality. Beyond this exploration of Beyond the Pleasure Principle, in the third part of the article I turn to a reading of Lacan’s interpretation of Freud’s work, where viral law becomes a story of cybernetics and nihilistic mechanisation. Here, perfect mechanisation, and the endless oscillation between message and noise, looks a lot like living death. Finally, I take up Derrida’s critique of Jacob’s molecular biology and, by extension, Freud’s theory of microbial immorality, that he thinks privileges an idea of repetitive sameness and opens up a space for cultural politics concerned with immunity against otherness. Derrida’s key point here is that this biological fantasy ignores the reality of viral sex that enables evolution to happen. What this means is that the other, even in its microbial form, is ever present, and that we must recognise the importance of difference to the possibility of social, political, and economic change.

Social media can indirectly have a great influence on the current law enforcement system. In principle, public participation through social media has a positive impact arising from community control on social media, one of which is as an effort in law enforcement to be more transparent and accountable. Regarding cases of domestic violence, in fact, until now, there are still many victims of domestic violence who do not speak up to voice their suffering. Even though the case has gone (...) class='Hi'>viral on social media and has received much public attention, the cases will likely be quickly processed by law enforcement officials and escorted by the community on social media, so it is hoped that the victim will get justice. The research method used is descriptive analysis, which describes or provides an overview of the object being researched, either through data or through samples collected as they are. A form of analysis is carried out, and a conclusion is made that applies to the general public. The materials used in this study are literature, consisting of primary, secondary, and tertiary materials. The phenomenon of domestic violence (KDRT) has been increasing lately. Data collected from January to August 2024 recorded 15,490 cases of violence. Domestic violence cases dominated the report, with a total of 9,503 cases. One of the law enforcement processes in tackling domestic violence cases is also triggered by the virality that arises in social media. (shrink)

In a number of membrane-bound viruses, ion channels are formed by integral membrane proteins. These channel proteins include M2 from influenza A, NB from influenza B, and, possibly, Vpu from HIV-1. M2 is important in facilitating uncoating of the influenza A viral genome and is the target of amantadine, an anti-influenza drug. The biological roles of NB and Vpu are less certain. In all cases, the protein contains a single transmembrane α-helix close to its N-terminus. Channels can be formed (...) by homo-oligomerization of these proteins, yielding bundles of transmembrane helices that span the membrane and surround a central ion-permeable pore. Molecular modeling may be used to integrate and interpret available experimental data concerning the structure of such transmembrane pores. This has proved successful for the M2 channel domain, where two independently derived models are in agreement with one another, and with solid-state nuclear magnetic resonance (NMR) data. Simulations based on channel models may yield insights into possible ion conduction and selectivity mechanisms. BioEssays 20:992–1000, 1998. © 1998 John Wiley & Sons, Inc. (shrink)

This research aims to gain insight on the perception that minors have of viral challenges as an entertainment format and the motivations behind their participation in this digital entertainment phenomenon.

For minors, viral challenges represent a form of entertainment in an interactive context, perceived as innocuous, ephemeral content from which nothing more is required than for the (...) user to have a good time. This appears to lead the minors interviewed to ignore the meaning and origin of the viral challenges they visualise and share, neither do they regard this to be necessary. It is also important to underline the relativisation of risk and danger in favour of spectacularisation and virality. (shrink)

From Editors' Introduction: "With our invitation to turn over (re-turn) hospitality in these times Marietta Radomska’s response combines her own research within the emerging field of Queer Death Studies6 with a detailed reading of the coronavirus disease pandemic. In her essay, “Viral queerings, amplified vulnerabilities”, Marietta seeks to subvert normative and simplified understandings of our present. Following the thread that the pandemic affects some bodies more than others, Marietta highlights how “the exploitation and degradation of nature mixed with intensifying (...) socio-economic inequalities directly contribute to the emergence of zoonoses”. Untangling the myth of the containable body and human-exceptionalism, Marietta challenges which lives are considered grievable drawing our attention to “more-than-human necropolitics”. In queering the pandemic she asks us to “reimagine the ways we relate to human and nonhuman others, perhaps in a more hospitable register”." Edited by Yvonne Billimore and Jussi Koitela. (shrink)

It is becoming clear that the post‐translational modification of histone and non‐histone proteins by acetylation is part of an important cellular signaling process controling a wide variety of functions in both the nucleus and the cytoplasm. Recent investigations designate this signaling pathway as one of the primary targets of viral proteins after infection. Indeed, specific viral proteins have acquired the capacity to interact with cellular acetyltransferases (HATs) and deacetylases (HDACs) and consequently to disrupt normal acetylation signaling pathways, thereby (...) affecting viral and cellular gene expression. Here we review the targeting of cellular HATs and HDACs by viral proteins and highlight different strategies adopted by viruses to control cellular acetylation signaling and to accomplish their life cycle.

Early in the COVID-19 pandemic, when the novel coronavirus SARS-CoV-2 spilled into the United States and spawned devastating outbreaks in Albany, Georgia, and multiple other cities, news media organizations served an important public health function. Journalists gathered and reported information about a new infectious disease peril, and they used increasing tolls of cases, hospitalizations, and deaths as a shorthand form of risk communication. However, there were ample reasons from the start to question the completeness, accuracy, and fairness of the information (...) that local news sources provided, and reporters repeated in numerous accounts of the Albany hotspot from March to July 2020. The story that went viral adhered to and supported a standard but strikingly deficient explanation of how novel infectious diseases wreak widespread havoc. The conventional outbreak narrative, exemplified by the Albany news coverage, frames causality, spread, and repercussions in ways that implicate personal behaviors while diminishing or disregarding population-level drivers of epidemics and the contribution of institutional lapses in healthcare safety. A second, closely related ramification of this responsibility framing is stigmatization of specific individuals or groups when they are singled out on the basis of an attribute, such as their race/ethnicity, religion, or sexual orientation, and identified as bearers and spreaders of a communicable disease. As the COVID-19 pandemic once again demonstrated, and the Albany story epitomizes, the conventional outbreak narrative sends strong stigma cues while leaving large gaps in the information needed to contend more equitably and effectively with emerging infectious diseases.

Polioviruses of reduced neurovirulence contain point mutations in the viral RNA that are responsible for the attenuated phenotype. Two such point mutations have been identified in the genomes of the Sabin live oral vaccine strains, one in the 5′‐noncoding region of the viral RNA, and one in capsid polypeptide VP3.

In plants, virus‐derived double‐stranded RNA is processed into small interfering (si)RNAs by RNAse III‐type enzymes. siRNAs are believed to guide an RNA‐induced silencing complex (RISC) to promote sequence‐specific degradation (or ‘slicing’) of homologous viral transcripts. This process, called RNA silencing, likely involves Argonaute (AGO) proteins that are known components of plant and animal RISCs. Plant viruses commonly counteract the silencing immune response by producing suppressor proteins, but the molecular basis of their action has remained largely unclear. A recent study (...) by Zhang and colleagues1 now shows that the 2b suppressor of Cucumber mosaic virus directly interacts with Arabidopsis AGO1 and inhibits its slicing activity, suggesting that AGO1 might be a component of the elusive plant antiviral RISC.

This has proved successful for the M2 channel domain, where two independently derived models are in agreement with one another, and with solid-state nuclear magnetic resonance (NMR) data. Simulations based on channel models may yield insights into possible ion conduction and selectivity mechanisms. BioEssays 20:992–1000, 1998. © 1998 John Wiley & Sons, Inc. (shrink)

Whereas telomeres protect terminal ends of linear chromosomes, telomerases identify natural chromosome ends, which differ from broken DNA and replicate telomeres. Although telomeres play a crucial role in the linear chromosome organization of eukaryotic cells, their molecular syntax most probably descended from an ancient retroviral competence. This indicates an early retroviral colonization of large double-stranded DNA viruses, which are putative ancestors of the eukaryotic nucleus. This contribution demonstrates an advantage of the biosemiotic approach towards our evolutionary understanding of telomeres, telomerases, (...) other reverse transcriptases and mobile elements. Their role in genetic/genomic content organization and maintenance is no longer viewed as an object of randomly derived alterations (mutations) but as a highly sophisticated hierarchy of regulatory networks organized and coordinated by natural genome-editing competences of viruses.

ABSTRACT The metaphor of ‘viral modernity’ denotes an era characterized by communal experiences of how viruses, be they in the shape of physical, virtual or symbolic forms, permeate and shape social and cultural life. To think educative justice in viral modernity thus require a radical move beyond the surfaces of conventional paradigms in order to reach at a deep-seated understanding of the phenomena of education and justice itself. Motivated by this ambition, I here present a Badiouan reading of (...) educative justice in relation to the aims and mission of philosophy of education. I start by briefly mapping out current educational philosophical paradigms and their ways of treating the issue of justice. Next, I contrast these orthodoxies to a Badiouan model. My overall ambition is to promote a philosophy of education that avoids philosophical doctrines, old and new, while simultaneously carrying a potential for unveiling the phenomenon of justice as educative truths-in-worlds.

Two different kinds of collections have been used to anticipate influenza pandemics: viral strains and bird specimens. These collections have been organized in museums and data banks to fill the gaps when specimens were decaying or when viral strains were missing. This article asks how collecting practices changed when such collections integrated specimens from China, considered a reservoir of influenza viruses and bird species, following a recurrent critical trope that Chinese specimens were missing. The article shows that techniques (...) for hunting viruses and birds were used to accumulate information so as to mitigate the global threat of species extinction. It suggests that in sentinel territories, museums transform samples and specimens into signs and images of future catastrophic events. (shrink)

Since the outbreak of the COVID-19 pandemic, there has been countless debate about the virus. The role discourse plays in this pandemic is tightly associated with the impact of pandemic on society....

Public intellectuals today must be understood in relation to the concept of ‘viral modernity’, characterised by viral and open media and technologies of post-truth that reveal the dramatic transformations of the ‘public’, its forms and its future possibilities. The history, status and role of the public intellectual are constituted by both the network of law in liberal society and above all the primacy of the concept of freedom of expression. The task of public intellectuals was to define, analyse (...) and protect these rights by speaking truth to power. Both Wittgenstein and Foucault as exemplary intellectuals distinguished themselves by problematising truth and showing that truth-telling is an aspect of self-transformation and the intellectual form of life.

Throughout the COVID-19 pandemic the use of the term “hero” has been widespread. This is especially common in the context of healthcare workers and it is now unremarkable to see large banners on hospital exteriors that say “heroes work here”. There is more to be gleaned from the rhetoric of heroism than just awareness of public appreciation, however. Calling physicians and nurses heroes for treating sick people indicates something about the concept of medicine and medical professionals. In this essay, I (...) will examine three aspects of the social role of medicine exposed by the language of heroism. One, if a hero is someone who goes above and the call of duty, then does that mean exposing oneself to risk of infection is no longer a duty of physicians? If so, does that mean the “profession” of medicine is much like any other business? Two, physicians and nurses are not the only “heroes” this go-around. Anyone deemed essential to the US “infrastructure” is designated by the US government as having “special responsibilities” to remain at their posts for the public good, which explicitly puts physicians in the same category as sewage workers and grocery store cashiers. Three, what does it mean to belong to a profession that does have self-sacrifice and risk-taking as part of its mission—especially a profession that rarely gets called upon to practice these obligations?

pseudo-Master's thesis Since Jacques Derrida’s 1989 essay “Force of Law: the Mystical Foundations of Authority,” Carl Schmitt has been a perennial subject of Derrida’s political critique. I will argue that Derrida’s concept of auto-immunity is uniquely applicable to Derrida’s interpretation of Schmitt’s political philosophy. Therefore, my argument will consist of two interrelated but equally divergent parts; the digressive structure will attempt to mimic Derrida’s complex style of weaving opposed concepts into a coherent whole. First, I will demonstrate the many forms (...) of Derrida’s concept of auto-immunity. Second, I will exhibit how this schema uniquely applies to Derrida’s criticisms of Schmitt and the contemporary state of politics. (shrink)

November 4th-5th, 2012 at Kyoto University. Organizers: Hisashi Nakao & Pierre-Alain Braillard.

The authors of this insightful and urgent collection both use the metaphor of evil as a virus or contagion and conceptualize the COVID-19 virus as a manifestation of evil to reconsider the purpose of philosophy in and for a pandemic.
