Here, the authors systematically assess interrater variability among expert pathologists reviewing histopathological images and clinical metadata of melanoma-suspicious lesions collected at eight German hospitals.

This study explores the use of quantum computing to address multi-objective optimization challenges. By using a low-depth quantum approximate optimization algorithm to approximate the optimal Pareto front of multi-objective weighted max-cut problems, the authors demonstrate promising results—both in simulation and on IBM Quantum hardware—surpassing classical approaches.

CD123 expression on leukemic stem and progenitor cells (LSPCs) and leukemic blasts representing a promising therapeutic target. However previous CD123-targeting approaches had limited efficacy and safety concerns. The authors here evaluate the bispecific CD123/CD16A innate cell engager AFM28 and manifest its efficacy both in vitro and in vivo, which is mediated by NK cells.

Gut microbiota contribute to the pathogenesis of ulcerative colitis (UC), but the molecular mechanisms are still unclear. Here the authors show that colonic fluid from patients with UC is enriched for bacteria extracellular vesicles (BEV) coated with host IgA, and that these IgA-coated BEV may activate CD89⁺ immune cells to aggravate inflammation and colitis in mouse models.

The bat sarbecovirus RaTG13 is a close relative of SARS-CoV-2, but its spike protein doesn’t efficiently bind human ACE2. Here, the authors show that exchange of spike residue 403 between RaTG13 and SARS-CoV-2 spike proteins affects binding to human ACE2 and entry of pseudotyped viruses.

Mass gathering events represent a risk for transmission of SARS-CoV-2. Here, the authors describe an experimental indoor test event in which individual contacts were measured and use aerosol and epidemiological modelling to evaluate transmission risks of different types of restrictions in the arena.

Using multi-ancestry genome-wide association study and fine-mapping, 298 loci and 36 credible genes are identified in the aetiology of bipolar disorder.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

In this Stage 2 Registered Report, Buchanan et al. show evidence confirming the phenomenon of semantic priming across speakers of 19 diverse languages.

Remembering Emil von Behring, one of the founders of immunology, 100 years after his death.

Authors utilise a murine model of infection to provide mechanistic insight into how antimicrobial therapy may be a predisposing risk factor for hospital-acquired pneumonia. They show that antibiotic-induced microbiota perturbations compromise inflammatory monocytes and thereby impair antibacterial defence.

Femtosecond laser spectroscopy has contributed to our understanding of structure and function of matter. Here, the authors explore the applicability of superfluid helium nanodroplets as a sample preparation method that allows investigation of previously inaccessible classes of tailor-made or fragile molecular systems.

One of the goals for devices using organic semiconductors is to make the materials themselves multifunctional or tunable, reducing the complexity of the device. Now, a film created by blending two components is shown to be phototunable with bistable energy levels and has been used in an organic thin-film transistor.

Stefan Kaufmann looks to the future of vaccination against tuberculosis. By drawing on past and present vaccination approaches, he proposes that the most successful strategy for preventing tuberculosis in the future will combine different vaccine candidates and use a prime–boost approach.

Whereas federal expenditure in the United States on the development of an HIV/AIDS vaccine is approximately $250 million, only $25 million is spent on research and development for a malaria vaccine. It is not malaria but tuberculosis (TB) that is the poor relation. Government funds for a vaccine to fight this disease are in single figure millions. Stefan Kaufmann of the Max Planck Institute for Infection Biology examines obstacles in addition to funding that hinder the development of a new TB vaccine.

The A.27 SARS-CoV-2 lineage spread globally in 2021 but did not become dominant. Here, the authors show that A.27 shares some mutations in the spike gene that are present in variants of concern, but lacks the D614G mutation, indicating independent evolution of immune escape properties.

Asexual reproduction is thought to be an evolutionary dead end in eukaryotes because deleterious mutations will not be purged effectively. Here, Brandt and colleagues show that anciently asexual oribatid mites in fact have reduced accumulation of deleterious mutations compared to their sexual relatives.

Cytokine storm seems to be a common feature of severe COVID-19 pathology. Here, the authors show a reduced rate of SARS-CoV2 positivity in a large population of patients with immune-mediated inflammatory diseases if they are already being treated with cytokine or JAK inhibitors, indicating these treatments are safe to continue and are possibly protective against COVID19.

The integration of DNA methylation profiling and targeted sequencing with neuropathology improves the diagnostic accuracy of central nervous system tumors in a population-based cohort of more than 1,200 newly diagnosed pediatric patients.

The conversions of methanol or methyl chloride over zeolite catalysts are promising processes to produce valuable hydrocarbons, but their mechanisms are still not fully understood. Now these are evaluated using operando photoelectron photoion coincidence spectroscopy, which enables the direct observation of elusive intermediates such as methyl radicals or ketene.

The Grand Ethiopian Renaissance Dam will be hugely beneficial to Ethiopia, but has raised tensions with neighbouring countries that rely on flow from the Blue Nile. Sterl et al. present scenarios for dam operation coupled with solar and wind power generation that could mitigate some of these concerns.

Oh, Hölzer et al., discuss the multidisciplinary approach used for monitoring the genomic and virological evolution of SARS-CoV-2 during the COVID-19 pandemic and its implications on public health in Germany. They emphasize the need for continuous surveillance and adaptation of public health strategies to address evolving viral threats.
