"Only someone with zero understanding of radiology would say something so naive." Just weeks after the largest nurses strike in the New York City history, the CEO of NYC Health and Hospitals has a bold vision for a future where AI, not human radiologists, examines and diagnoses X-rays. At a panel held by Crain’s New York Business, Mitchell Katz, president and CEO of New York’s 11-hospital public benefit corporation, made overt gestures at his desire to replace highly trained radiology experts

Plants lack specialized immune cells and instead rely on coordinated cellular responses to restrict pathogen invasion while preserving tissue integrity. How plant immunity spatially organizes these responses remains unclear. Using live-cell reporters in Arabidopsis infected with Pseudomonas syringae, we show that effector-triggered immunity, superimposed on pattern-triggered immunity, establishes a sustained yet spatially confined immune architecture at the infection front. Defense activation persists for days but remains restricted to a narrow ring of cells surrounding viable bacterial microcolonies. Over time, immune activity spreads to adjacent layers, forming a coordinated, multilayered defense zone. This zonation extends beyond transcriptional activation to polarized callose deposition at pathogen-facing cell walls, reinforcing a localized containment boundary that limits pathogen spread. Consistent with previous single-reporter studies, simultaneous visualization of salicylic acid (SA) and jasmonic acid (JA) biosynthesis and response markers reveals a radial hormone gradient, with SA-enriched cells proximal to bacterial colonies and JA-enriched cells in surrounding regions. Individual cells predominantly activate one pathway, indicating that SA-JA antagonism is resolved through spatial compartmentalization across neighboring cells. Together, these findings establish immune zonation as a strategy for robust pathogen containment while minimizing collateral tissue damage. ### Competing Interest Statement The authors have declared no competing interest.

Long-read sequencing has shown a rapid technological development during the last years. It has been established as the standard method for the sequencing of plant genomes and has also gained importance for full plasmid sequencing. As Sanger sequencing has a limited read length of about 1 kb, long read sequencing offers a great advantage, as the full plasmid can be sequenced in one read. Here, we present a cost-effective workflow to sequence full plasmids and compare the results against an expectation. The per plasmid cost of this workflow is determined by the number of plasmids investigated simultaneously, but can be lower than the price of a single Sanger sequencing reaction. We developed a workflow for automatic data processing, which allows us to complete sequencing and data analysis within a day. ### Competing Interest Statement The authors have declared no competing interest.

Abstract. Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncertainty space. The proposal also includes plans for long-term extensions (up to 2500 AD) to study long-term impacts, climate change-related processes on long timescales, and (ir)reversibility. This proposal forms the basis for further implementation of the framework in terms of the derivation of emissions and land use pathways for use by Earth system models and additional variants for adaptation and mitigation studies.

Root-knot nematodes are obligate plant parasites that cause substantial agricultural losses worldwide. They induce highly specialized, metabolically hyperactive feeding sites within host roots, which serve as their sole source of nutrients throughout their life cycle. The formation and maintenance of these feeding sites depend on the manipulation of host developmental pathways by nematode-derived secretions. Phytosulfokines (PSKs) are small plant peptide hormones that regulate cell division, tissue expansion, and growth responses, processes essential for feeding site development. Here, we identify root-knot nematode genes predicted to encode peptides with a conserved PSK functional motif. These genes are predominantly expressed during the early stages of infection and localize to secretory glands, suggesting a role in early parasitism. Moreover, silencing PSK-like gene expression reduces root gall formation and nematode reproduction. Together, these findings reveal that root-knot nematodes deploy PSK-like peptides as virulence factors to promote successful parasitism, providing the first report of PSK peptide mimicry in any plant pathogen. ### Competing Interest Statement The authors have declared no competing interest.
