Moral enhancement and cheapened achievement: Psychedelics, virtual reality and AI.

A prominent critique of cognitive or athletic enhancement claims that certain performance-improving drugs or technologies may 'cheapen' resulting achievements. Considerably less attention has been paid to the impact of enhancement on the value of moral achievements. Would the use of moral enhancement (bio)technologies, rather than (solely) 'traditional' means of moral development like schooling and socialization, cheapen the 'achievement' of morally improving oneself? We argue that, to the extent that the 'cheapened achievement' objection succeeds in the domains of cognitive or athletic enhancement, it could plausibly also succeed in the domain of moral enhancement-but only regarding certain forms.

Endothelial c-Src Mediates Neovascular Tuft Formation in Oxygen-Induced Retinopathy.

Vascular retinopathy, characterized by abnormal blood vessel growth in the retina, frequently results in vision impairment or loss. Neovascular tufts, a distinctive pathologic feature of this condition, are highly leaky blood vessel structures, exacerbating secondary complications. Despite their clinical significance, the mechanisms underlying tuft development are not fully elucidated, posing challenges for effective management and treatment of vascular retinopathy.

Cognitive Enhancement, Hyperagency, and Responsibility Explosion.

Hyperagency objections appeal to the risk that cognitive enhancement may negatively impact our well-being by giving us too much control. I charitably formulate and engage with a prominent version of this objection due to Sandel (2009) -viz., that cognitive enhancement may negatively impact our well-being by creating an "explosion" of responsibilities.

c-Src-induced vascular malformations require localised matrix degradation at focal adhesions.

Endothelial cells lining the blood vessel wall communicate intricately with the surrounding extracellular matrix, translating mechanical cues into biochemical signals. Moreover, vessels require the capability to enzymatically degrade the matrix surrounding them, to facilitate vascular expansion. c-Src plays a key role in blood vessel growth, with its loss in the endothelium reducing vessel sprouting and focal adhesion signalling.

Tyrosine-protein kinase Yes controls endothelial junctional plasticity and barrier integrity by regulating VE-cadherin phosphorylation and endocytosis.

Vascular endothelial (VE)-cadherin in endothelial adherens junctions is an essential component of the vascular barrier, critical for tissue homeostasis and implicated in diseases such as cancer and retinopathies. Inhibitors of Src cytoplasmic tyrosine kinase have been applied to suppress VE-cadherin tyrosine phosphorylation and prevent excessive leakage, edema and high interstitial pressure. Here we show that the Src-related Yes tyrosine kinase, rather than Src, is localized at endothelial cell (EC) junctions where it becomes activated in a flow-dependent manner.

Signatures of adaptive decreased virulence of deformed wing virus in an isolated population of wild honeybees ().

Understanding the ecological and evolutionary processes that drive host-pathogen interactions is critical for combating epidemics and conserving species. The mite and deformed wing virus (DWV) are two synergistic threats to Western honeybee () populations across the globe. Distinct honeybee populations have been found to self-sustain despite infestations, including colonies within the Arnot Forest outside Ithaca, NY, USA.

An E-cadherin-actin clutch translates the mechanical force of cortical flow for cell-cell contact to inhibit epithelial cell locomotion.

Adherens junctions (AJs) allow cell contact to inhibit epithelial migration yet also permit epithelia to move as coherent sheets. How, then, do cells identify which contacts will inhibit locomotion? Here, we show that in human epithelial cells this arises from the orientation of cortical flows at AJs. When the leader cells from different migrating sheets make head-on contact with one another, they assemble AJs that couple together oppositely directed cortical flows.

PET-RAFT Polymerization of Star Polymers with Folded ortho-Phenylene Cores.

ortho-Phenylenes are one of the simplest classes of aromatic foldamers, adopting helical geometries because of aromatic stacking interactions. The folding and misfolding of ortho-phenylenes are slow on the NMR timescale at or below room temperature, allowing detection of folding states using H NMR spectroscopy. Herein, an ortho-phenylene hexamer is coupled with a RAFT chain transfer agent (CTA) on each repeat unit.

Macrophage ACE2 is necessary for SARS-CoV-2 replication and subsequent cytokine responses that restrict continued virion release.

Macrophages are key cellular contributors to the pathogenesis of COVID-19, the disease caused by the virus SARS-CoV-2. The SARS-CoV-2 entry receptor ACE2 is present only on a subset of macrophages at sites of SARS-CoV-2 infection in humans. Here, we investigated whether SARS-CoV-2 can enter macrophages, replicate, and release new viral progeny; whether macrophages need to sense a replicating virus to drive cytokine release; and, if so, whether ACE2 is involved in these mechanisms.

Pharmacological cognitive enhancement and the value of achievements: An intervention.

Pharmacological cognitive enhancements nontherapeutically improve cognitive functioning, though recent critics have challenged their use by claiming that cognitive success, aided by the use of cognitive enhancement, is less valuable than otherwise. We criticize two recent responses to this objection, due to Carter and Pritchard and Wang, and propose a different response on behalf of proponents of cognitive enhancement that is shown to be more promising.

Longitudinal Testing of Antibodies in Horses Located near a Leptospirosis Outbreak in Alpacas.

The objectives of this study were to determine if horses located near an outbreak of leptospirosis in alpacas had titres indicative of a previous or current infection and, if so, to determine the magnitude in change of titres over time. Further, the objective was to determine if horses with high titre results were shedding in their urine. Blood samples were collected from twelve horses located on or next to the farm with the outbreak in alpacas, on day zero and at four subsequent time points (two, four, six and nine weeks).

Stochastic Local Breakdown of Oxide Film on Ni from Identical-Location Imaging: One Single Site at a Time.

The electrochemical breakdown of a metal oxide film can directly affect the performance of functional electrochemical devices. However, revealing the structural insight into the breakdown sites is challenging because of heterogeneity: different breakdown sites are spatially distributed over the surface. Herein, we combine scanning electrochemical cell microscopy with identical-location microscopies to reveal the heterogeneity in the breakdown of NiO film on Ni in a site-by-site manner.

Improved Durability to SARS-CoV-2 Vaccine Immunity following Coimmunization with Molecular Adjuvant Adenosine Deaminase-1.

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines have demonstrated strong immunogenicity and protection against severe disease, concerns about the duration and breadth of these responses remain. In this study, we show that codelivery of plasmid-encoded adenosine deaminase-1 (pADA) with SARS-CoV-2 spike glycoprotein DNA enhances immune memory and durability in vivo. Coimmunized mice displayed increased spike-specific IgG of higher affinity and neutralizing capacity as compared with plasmid-encoded spike-only-immunized animals.

Nanoscale Colocalized Electrochemical and Structural Mapping of Metal Dissolution Reaction.

Understanding the structure-activity relationship in electrochemical metal dissolution reactions is fundamentally important, from designing higher density batteries to mitigating corrosions. The kinetics of metal dissolution reaction is highly dependent on surface structures, including grain boundaries and local defects. However, directly probing the electrochemical activity at these sites is difficult because the conventional bulk electrochemistry measures an averaged kinetics, obscuring the structure-activity correlation.

What makes administrative data "research-ready"? A systematic review and thematic analysis of published literature.

Introduction: Administrative data are a valuable research resource, but are under-utilised in the UK due to governance, technical and other barriers (e.g., the time and effort taken to gain secure data access).

Cognitive enhancement and authenticity: moving beyond the Impasse.

In work on the ethics of cognitive enhancement use, there is a pervasive concern that such enhancement will-in some way-make us less authentic (e.g., Bublitz and Merkel 2009; Juth 2011).

Formation of styrene maleic acid lipid nanoparticles (SMALPs) using SMA thin film on a substrate.

Despite the important role of membrane proteins in biological function and physiology, studying them remains challenging because of limited biomimetic systems for the protein to remain in its native membrane environment. Cryo electron microscopy (Cryo-EM) is emerging as a powerful tool for analyzing the structure of membrane proteins. However, Cryo-EM and other membrane protein analyses are better studied in a native lipid bilayer.

Plasma pharmacokinetics, pulmonary disposition, and safety of subcutaneous gamithromycin in alpacas.

The study objective was to determine the disposition of gamithromycin in plasma, peripheral blood polymorphonuclear cells (PMNs), pulmonary epithelial lining fluid (PELF), and bronchoalveolar lavage (BAL) cells in alpacas. A single subcutaneous injection of gamithromycin (6.6 mg/kg) was administered to six healthy adult alpacas.

Pre-vaccination frequency of circulatory Tfh is associated with robust immune response to TV003 dengue vaccine.

It has been estimated that more than 390 million people are infected with Dengue virus every year; around 96 millions of these infections result in clinical pathologies. To date, there is only one licensed viral vector-based Dengue virus vaccine CYD-TDV approved for use in dengue endemic areas. While initially approved for administration independent of serostatus, the current guidance only recommends the use of this vaccine for seropositive individuals.

Virtual Reality and Technologically Mediated Love.

An emerging line of research in bioethics questions whether enhanced love is less significant or valuable than otherwise, where "enhanced love" generally refers to cases where drugs (e.g., oxytocin, etc.

Endothelial cells are not productively infected by SARS-CoV-2.

Objectives: Thrombotic and microvascular complications are frequently seen in deceased COVID-19 patients. However, whether this is caused by direct viral infection of the endothelium or inflammation-induced endothelial activation remains highly contentious.

Methods: Here, we use patient autopsy samples, primary human endothelial cells and an model of the pulmonary epithelial-endothelial cell barrier.

Life-threatening diarrhea in neuroendocrine tumors: two case reports.

Background: Neuroendocrine tumors are rare, heterogeneous neoplasms that produce a wide variety of clinical symptoms. Diarrhea in neuroendocrine tumors is incredibly common and is usually benign in nature. We report two extreme cases of diarrhea in metastatic neuroendocrine tumors that threatened fatality and provide evidence for steroids as a novel agent in the management of vasoactive intestinal peptide tumors.
