<li><strong>Virological characteristics of the SARS-CoV-2 BA.2.86 variant</strong> -
|
||
<div>
|
||
In late 2023, a lineage of SARS-CoV-2 emerged and was named the BA.2.86 variant. BA.2.86 is phylogenetically distinct from other Omicron sublineages identified so far, displaying an accumulation of over 30 amino acid mutations in its spike protein. Here, we performed multiscale investigations to reveal the virological characteristics of the BA.2.86 variant. Our epidemic dynamics modeling suggested that the relative reproduction number of BA.2.86 is significantly higher than that of EG.5.1. Experimental studies showed that four clinically-available antivirals were effective against BA.2.86. Although the fusogenicity of BA.2.86 spike is similar to that of the parental BA.2 spike, the intrinsic pathogenicity of BA.2.86 in hamsters was significantly lower than that of BA.2. Since the growth kinetics of BA.2.86 is significantly lower than that of BA.2 in both in vitro cell cultures and in vivo, it is suggested that the attenuated pathogenicity of BA.2.86 is due to its decreased replication capacity.

<li><strong>Leveraging a self-cleaving peptide for tailored control in proximity labeling proteomics</strong> -
|
||
<div>
|
||
Protein-protein interactions play an important biological role in every aspect of cellular homeostasis and functioning. Proximity labeling mass spectrometry-based proteomics overcomes challenges typically associated with other methods, and has quickly become the current state-of-the-art in the field. Nevertheless, tight control of proximity labeling enzymatic activity and expression levels is crucial to accurately identify protein interactors. Here, we leverage a T2A self-cleaving peptide and a non-cleaving mutant to accommodate the protein-of-interest in the experimental and control TurboID setup. To allow easy and streamlined plasmid assembly, we built a Golden Gate modular cloning system to generate plasmids for transient expression and stable integration. To highlight our T2A Split-link design, we applied it to identify protein interactions of the glucocorticoid receptor and SARS-CoV-2 nucleocapsid and NSP7 proteins by TurboID proximity labeling. Our results demonstrate that our T2A split-link provides an opportune control that builds upon previously established control requirements in the field.

<li><strong>Resistance mechanisms of SARS-CoV-2 3CLpro to the non-covalent inhibitor WU-04</strong> -
|
||
<div>
|
||
Drug resistance poses a significant challenge in the development of effective therapies against SARS-CoV-2. Here, we identified two double mutations, M49K/M165V and M49K/S301P, in the 3C-like protease (3CLpro) that confer resistance to a novel non-covalent inhibitor, WU-04. Crystallographic analysis indicates that the M49K mutation destabilizes the WU-04 binding pocket, impacting the binding of WU-04 more significantly than the binding of 3CLpro substrates. The M165V mutation directly interferes with WU-04 binding. The S301P mutation, which is far from the WU-04 binding pocket, indirectly affects WU-04 binding by restricting the rotation of 3CLpro's C-terminal tail and impeding 3CLpro dimerization. We further explored 3CLpro mutations that confer resistance to two clinically used inhibitors: ensitrelvir and nirmatrelvir, and revealed a trade-off between the catalytic activity, thermostability, and drug resistance of 3CLpro. We found that mutations at the same residue (M49) can have distinct effects on the 3CLpro inhibitors, highlighting the importance of developing multiple antiviral agents with different skeletons for fighting SARS-CoV-2. These findings enhance our understanding of SARS-CoV-2 resistance mechanisms and inform the development of effective therapeutics.

<li><strong>OASIS: An interpretable, finite sample valid alternative to Pearson’s X2 for scientific discovery</strong> -
|
||
<div>
|

Contingency tables, data represented as counts matrices, are ubiquitous across quantitative research and data-science applications. Existing statistical tests are insufficient however, as none are simultaneously computationally efficient and statistically valid for a finite number of observations. In this work, motivated by a recent application in reference-free genomic inference (Chaung et. al. 2022), we develop OASIS (Optimized Adaptive Statistic for Inferring Structure), a family of statistical tests for contingency tables. OASIS constructs a test-statistic which is linear in the normalized data matrix, providing closed form p-value bounds through classical concentration inequalities. In the process, OASIS provides a decomposition of the table, lending interpretability to its rejection of the null. We derive the asymptotic distribution of the OASIS test statistic, showing that these finite-sample bounds correctly characterize the test statistic’s p-value up to a variance term. Experiments on genomic sequencing data highlight the power and interpretability of OASIS. The same method based on OASIS significance calls detects SARS-CoV-2 and Mycobacterium Tuberculosis strains de novo, which cannot be achieved with current approaches. We demonstrate in simulations that OASIS is robust to overdispersion, a common feature in genomic data like single cell RNA-sequencing, where under accepted noise models OASIS still provides good control of the false discovery rate, while Pearson’s <span class="math inline"><em>X</em><sup>2</sup></span> test consistently rejects the null. Additionally, we show on synthetic data that OASIS is more powerful than Pearson’s <span class="math inline"><em>X</em><sup>2</sup></span> test in certain regimes, including for some important two group alternatives, which we corroborate with approximate power calculations.

Making accurate forecasting of COVID-19 cases is essential for healthcare systems, with more than 650 million cases as of 4 January,1 making it one of the worst in history. The goal of this research is to improve the precision of COVID-19 case predictions in Russia, India, and Brazil, a transformer-based model was developed. Several researchers have implemented a combination of CNNs and LSTMs, Long Short-Term Memory (LSTMs), and Convolutional Neural Networks (CNNs) to calculate the total number of COVID-19 cases. In this study, an effort was made to improve the correctness of the models by incorporating recent advancements in attention-based models for time-series forecasting. The resulting model was found to perform better than other existing models and showed improved accuracy in forecasting. Using the data from different countries and adapting it to the model will enhance its ability to support the worldwide effort to combat the pandemic by giving more precise projections of cases.

Both viral infection and vaccination affect the antibody repertoire of a person. Here we demonstrate that the analysis of serum antibodies carries information not only on the virus type that caused the infection, but also on the specific virus variant. We developed a rapid multiplex assay providing a fingerprint of serum antibodies against five different SARS-CoV-2 variants, based on a microarray of virus antigens immobilized on the surface of a label-free reflectometric biosensor. We analyzed serum from plasma of convalescent subjects and vaccinated volunteers and extracted individual antibody profiles of both total immunoglobulin Ig and IgA fraction. We found that Ig level profiles were strongly correlated with the specific variant of infection or vaccination and that vaccinated subjects displayed larger quantity of total Ig and lower fraction of IgA relative to the population of convalescent unvaccinated subjects.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">

Protection against SARS-CoV-2 wanes over time, and booster uptake has been low, in part because of concern about side effects. We examined the relationships between local and systemic symptoms, biometric changes, and neutralizing antibodies (nAB) after mRNA vaccination. Data were collected from adults (n = 364) who received two doses of either BNT162b2 or mRNA-1273. Serum nAB concentration was measured at 1 and 6 months post-vaccination. Daily symptom surveys were completed for six days starting on the day of each dose. Concurrently, objective biometric measurements, including skin temperature, heart rate, heart rate variability, and respiratory rate, were collected. We found that certain symptoms (chills, tiredness, feeling unwell, and headache) after the second dose were associated with increases in nAB at 1 and 6 months post-vaccination, to roughly 140-160% the level of individuals without each symptom. Each additional symptom predicted a 1.1-fold nAB increase. Greater increases in skin temperature and heart rate after the second dose predicted higher nAB levels at both time points, but skin temperature change was more predictive of durable (6 month) nAB response than of short-term (1 month) nAB response. In the context of low ongoing vaccine uptake, our convergent symptom and biometric findings suggest that public health messaging could seek to reframe systemic symptoms after vaccination as desirable.

This paper explores differences in mortality dynamics between urban and rural areas of 20 European countries during the two pandemic years 2020 and 2021. The link between population density and the spread of communicable diseases is a well-established phenomenon, yet to what extent this results in a mortality gap after years of ongoing epidemics is a less explored question. We find pronounced and significant differences, with urban areas being harder hit by COVID-19 mortality in most countries.

Rationale: Sophisticated prognostic scores have been proposed for SARS-CoV-2 but do not always perform consistently. We conducted these meta-analyses to uncover why and to investigate the impact of vaccination and variants. Methods: We searched the PubMed database for the keywords: SARS-CoV-2 with biomarker and mortality. All studies published from 01/12/2020 to 31/03/2023 were surveyed. To aggregate the data, the meta library in R was used, and a random effects model fitted to obtain pooled AUCs and 95% confidence intervals for the European/North American, Asian, and overall datasets. Results: Biomarker effectiveness varies significantly in different continents. Admission CRP levels are a good prognostic marker for mortality in Asian countries, with a pooled area under curve (AUC) of 0.83 (95%CI 0.80-0.85), but only an average predictor of mortality in Europe/North America, with a pooled AUC of 0.67 (95%CI 0.63-0.71, P<0.0001). We observed the same pattern for D-dimer and IL-6. This variability explains why the proposed prognostic scores did not perform evenly. Notably, urea and troponin had pooled AUCs ≥0.78 regardless of location, implying that end-organ damage at presentation is a key prognostic factor. Very little data is available for vaccinated and variant cohorts but it appears that inflammatory biomarkers are performing less well. We note a significant lag from the pandemic advent to data availability and this has no doubt impacted on patient care. Conclusions: Biomarker efficacies vary considerably by region. It is imperative that the infrastructure for collecting clinical data should be put in place ahead of a future pandemic.

<li><strong>A preliminary mindsponge-based analysis of Generation Z’s relationship with technologies</strong> -

<div>
|

In terms of human-machine relationship, Gen Z, those who were born between 1997-2012, is the first generation who becomes productive members of society under so much technological disruption in a short period of time. For example, as a consequence of remote work caused by the COVID-19 pandemic, the global industry of emotional AI is forecasted to almost double from $19.5 in 2020 to $37.1 billion by 2026, at the compound annual growth rate of 11.3% in this period, according to Markets and Markets (Madhumita, 2021). Consequently, as Gen Z is poised to become the largest demographics for entry-level jobs (Pichler, Kohli & Granitz, 2021), they are expected to confront with a so much uncertain time of the various effects of emotion auto-tracking practices on mental and physical health, productivity, security, etc., have only gathered research interests in recent years. In this essay, using the mindsponge framework (Vuong and Napier, 2015), I reflect on the relationship of Gen Z with emotional AI technologies.

<li><strong>Learnings From The Case of Maple Refugees: A Story of Loot Boxes, Probability Disclosures, and Gamer Consumer Activism</strong> -
|
||
<div>
|

The article synthesises what we learned from reviewing the player activism of the “Maple refugee” incident and applies the insights to the European video game industry and commercial context. The Maple Refugee incident was perhaps one of the most disruptive video game incidents that occurred in South Korea in recent years. It saw tens of thousands of Korean players from the game Maple Story (Nexon, 2003) mobilised in unprecedented online and offline protests in Spring 2021. Together with players from other free-to-play (F2P) games, Maple Story players rallied against the industry norms of monetising with loot boxes and the industry self-regulatory approach to probability disclosures to address potential harms. This culminated in the social phenomenon of the proxy activism method of ’truck protests,’ rallies of crowdfunded rented trucks displaying protest messages instead of people mass-gathering in public during the COVID-19 pandemic. Based on the English timeline of the incident collated by Park et al. (2023), we dive deeper into the case with a multidisciplinary group of experts from game studies, law, and human-computer interaction and highlight various issues present in this case: the regulation of loot boxes and probability disclosures, the social pillars of player activism, player trust and theorycrafting, and game production. The paper contributes to the deepening of the industry’s understanding of F2P game business while diversifying the Western-centric discourse of the game research landscape by calling for further cross-cultural and cross-disciplinary inquiries into current video game issues.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|

While waning protection from vaccination and natural infection against SARS-CoV-2 infection is well-documented, recent analyses have also found waning of protection against severe COVID-19. This highlights a broader need to understand how different frequency of COVID-19 booster vaccines may mitigate the risk of severe COVID-19, while accounting for waning of protection and differential risk by age and immune status. Here we show that more frequent COVID-19 booster vaccination (every 6-12 months) in older age groups and the immunocompromised population would effectively reduce the burden of severe COVID-19, while frequent boosters in the younger population may only provide modest benefit against severe disease. Analyzing United States COVID-19 surveillance and seroprevalence data in a microsimulation model, we estimated that in persons 75+ years, annual and semiannual boosters would reduce annual absolute risk of severe COVID-19 by 199 (uncertainty interval: 188-229) and 368 (344-413) cases per 100,000 persons, respectively, compared to a one-time booster dose. In contrast, for persons 18-49 years, the model estimated that annual and semiannual boosters would reduce annual absolute risk of severe COVID-19 by 14 (11-19) and 26 (21-35) cases per 100,000 persons, respectively, compared to a one-time booster dose. Persons with prior infection had lower benefit of more frequent boosting, while immunocompromised persons had larger benefit. Scenarios with emerging variants with immune evasion increased the benefit of more frequent variant-targeted boosters. This study underscores the benefit of considering key risk factors to inform frequency of COVID-19 booster vaccines in public health guidance, and ensuring at least annual boosters in high-risk populations.

<li><strong>Neglected consequences of spatio-temporal heterogeneity and dispersal: Metapopulations, the inflationary effect, and real-world consequences for public health</strong> -
|
||
<div>
|
||
The metapopulation perspective is an important conceptual framework in ecology, biogeography, and evolutionary ecology. Metapopulations are spatially distributed populations linked by dispersal. Both metapopulation models and their community and ecosystem level analogues, metacommunity and meta-ecosystem models, tend to be more stable regionally than locally and display an enhancement in abundance because of the interplay of spatio-temporal heterogeneity and dispersal (an effect that has been called the "inflationary effect"). We highlight the essential role of spatio-temporal heterogeneity in metapopulation biology, sketch empirical demonstrations of the inflationary effect, and provide a mechanistic interpretation of how the inflationary effect arises and impacts population growth and abundance. The spread of infectious disease is used to illustrate how this effect, emerging from the interplay of spatiotemporal variability and dispersal, can have serious real-world consequences. Namely, failure to recognize the full possible effects of spatio-temporal heterogeneity likely enhanced the spread of COVID-19, and a comparable lack of understanding of emergent population processes at large scales may hamper the control and eradication of other infectious diseases. We finish by noting how the effects of spatio-temporal heterogeneity, including the inflationary effect, have implicitly played roles in many traditional themes in the history of ecology. The inflationary effect is implicit in processes explored in subdisciplines as far ranging as natural enemy-victim dynamics, species coexistence, and conservation biology. Seriously confronting the complexity of spatiotemporal heterogeneity has the potential to push many of these subdisciplines forward.

<li><strong>Experiencing herd immunity in virtual reality increases COVID-19 vaccination intention: Evidence from a large-scale field intervention study</strong> -
|
||
<div>
|
||
This study investigates the impact of an immersive virtual reality (VR) simulation of herd immunity on vaccination intentions and its potential underlying mechanisms. In this preregistered field study, N = 654 participants were randomly assigned to one of the three VR conditions: (1) Gamified Herd Immunity; (2) Gamified Herd Immunity + Empathy (with additional narrative elements); (3) Control (gamified with no vaccination-related content). In the Gamified Herd Immunity simulation, participants embodied a vulnerable person and navigated the wedding venue trying to avoid getting infected. A total of n = 455 participants with below maximum intentions to take a novel vaccine and without severe cybersickness symptoms were included in the analyses. The Gamified Herd Immunity + Empathy and the Gamified Herd Immunity conditions increased vaccination intentions by 6.68 and 7.06 points on a 0-100 scale, respectively, compared to 1.91 for the Control condition. The Gamified Herd Immunity + Empathy condition enhanced empathy significantly more than the Gamified Herd Immunity condition but did not result in higher vaccination intentions. The results suggest that immersive VR vaccination communication can effectively increase COVID-19 vaccine intentions; the effect is not solely a consequence of the technological experience itself and does not depend on empathy.
