The Pseudomonas syringae complex is a phylogenetic group comprising at least fifteen bacterial species and more than sixty host-specialized pathovars that collectively cause disease in over 180 plant species, including virtually all economically relevant crops. In highbush blueberry (Vaccinium corymbosum), infections manifest as blight of leafy tissues or cankers of woody tissues, both of which reduce plant health and productivity. Disease development depends on the transition of the bacterium from an epiphytic phase, in which cells remain adhered to plant surfaces, to an endophytic phase involving colonization of internal structures and the release of tissue-destroying virulence factors. Environmental conditions common in British Columbia—cool temperatures, high humidity and frequent precipitation—favour the growth and motility of epiphytic populations and thereby increase the likelihood of endophytic infection, making strategies that reduce surface populations before infection establishes an attractive line of defence.

The economic stakes are considerable. Global blueberry production reached roughly 2.14 billion kilograms in 2024, and Canada is the fourth-largest producer worldwide, accounting for nearly one-sixth of global output. Canadian blueberry exports were valued at approximately CAD $695 million in 2024, representing more than 65 percent of all Canadian fruit exports. Nearly 94 percent of the country’s highbush blueberry production occurs in British Columbia, where conditions favourable to the crop simultaneously favour bacterial growth and dispersal on plant surfaces. Traditional management has relied on copper-based biocides, but this approach damages the natural environment, can stunt plant growth through interference with the rhizosphere microbiome, and has been losing efficacy due to the spread of plasmid-borne copper resistance genes. Mitigation is often limited to the costly and unsustainable practice of pruning or culling infected plants.

Against this backdrop, the research team isolated bacteriophages from wastewater samples and from Pseudomonas syringae complex-infected blueberry plants collected at sites in the lower mainland and Okanagan valley regions, ultimately obtaining nineteen relatively stable phage isolates. Because phage predation by individual phage species is generally restricted to a subset of target strains and readily selects for resistant subpopulations, cocktail formulations of multiple distinct phages are typically employed to expand host range, improve efficacy and forestall resistance. The researchers used a semiquantitative spotting analysis to score infection interactions between each phage and a panel of twenty bacterial strains on a scale from zero to four, then excluded seven isolates—deemed weak specialists—that fell below median thresholds for both the number and strength of interactions. Twelve candidate phages advanced to genomic and functional characterization.

Whole-genome sequencing revealed extensive phylogenomic diversity among the candidates. Three isolates proved to be variants of a species within the genus Unosvirus, three were clonal duplicates belonging to Pifdecavirus, and a further group of four—three clonal and one diverged—may represent a novel species within an as-yet-undefined genus most closely related to Pseudomonas phage QdP_Psa3. The most striking discovery was phage φCB10, a jumbo phage with a genome of approximately 310 kilobases encoding 476 predicted coding sequences, most of them of unknown function. φCB10 was unrelated to the other lineages, most closely resembled Pseudomonas jumbo phage Psa21 at only 53.2 percent genomic similarity, and may represent the founding member of a novel genus. All twelve candidates were predicted to be obligately lytic, and bioinformatic screening found no lysogeny-associated genes, antimicrobial resistance determinants or metal resistance cassettes—characteristics considered indispensable for safe agricultural biocontrol.

Environmental stability assays revealed considerable heterogeneity among isolates. Exposure to ultraviolet radiation for one hour reduced viable titres of all phages, with the severity depending on wavelength: under UV-A at 365 nanometres, relevant to field conditions, only φCB16 fell below the detection limit, whereas UV-C at 254 nanometres drove the titres of most phages below detection. Freezing at −20 degrees Celsius produced a particularly polarizing split along predicted morphology: the three myovirus-like phages lost roughly 1.6 to 3.4 orders of magnitude in titre within a single day and became undetectable after 30 days, while podovirus-like isolates fared substantially better, with φCB02 and φCB05 showing no significant losses over the full month. This partitioning suggests that virion structural properties may broadly influence environmental persistence, a phenomenon the authors say warrants mechanistic investigation. Notably, some isolates appeared more stable at 22 degrees Celsius than at the conventional 4 degrees Celsius storage temperature, raising questions about the universality of phage storage conventions. Prolonged exposure to highly acidic conditions, potentially relevant given that blueberries thrive in soil at pH 4.0 to 5.5, was among the most consistently destabilizing stresses, although most phages retained functionality over biologically relevant timescales.

To quantify antibacterial activity, the team performed planktonic killing assays against eight virulent bacterial strains, summarizing 64 phage-host pairs with a Growth Reduction Coefficient derived from bacterial growth curves. Individual phage performance varied widely and depended strongly on the strain: the jumbo phage φCB10 achieved the highest median coefficient, 0.943, and was the only phage rated as strong across all targeted hosts, while roughly half of all single-phage interactions were deemed poor. The two most effective phages were variously combined with the four least effective to construct eight cocktails of three to five variants. Although cocktails did not significantly outperform individual phages overall, four formulations—φC_A, φC_B, φC_C and φC_D—achieved median coefficients above 0.75 and were rated as strong across the full host panel, and were carried forward to plant-based testing.

The decisive validation used a detached-leaf model in which young Draper-variety leaves were pretreated with phage cocktails and then inoculated with two highly virulent strains. Bacterial densities were substantially reduced in all pretreated leaves. At early timepoints corresponding to maximal bacterial densities in untreated leaves, the four cocktails induced reductions of 4.5 to 5.5 logs against strain B11 and 3.2 to 5.6 logs against strain B04. At the ten-day endpoint, two cocktails pushed B11 below the detection limit, and two others reduced B04 below detection. A variant of the Growth Reduction Coefficient calculated from bacterial density over time rated all four cocktails as strong against B11, with φC_D also strong against B04. Critically, ex planta performance correlated strongly with in vitro performance, suggesting that planktonic killing assays can serve as a useful proxy for more complex validation models in high-throughput screens.

Measurements of phage densities inside the leaves supported the conclusion that bacterial suppression was driven by ongoing lytic replication rather than a single contact-mediated kill. The mean in situ phage-to-bacterium ratio rose rapidly to a peak of roughly 1.8 × 10⁴ for treatments targeting B11 before decaying by day ten, and endpoint phage-to-bacterium ratios correlated positively with overall treatment efficacy. The authors interpret this as evidence that successful biocontrol depends not only on the killing efficiency of individual phages but also on their capacity to persist within the plant environment and maintain productive infections over extended periods.

The study establishes a framework for the systematic identification and evaluation of candidate phages for agricultural biocontrol, while flagging the questions that remain before field deployment. Detached-leaf assays cannot fully recapitulate whole-plant systems, and the authors emphasize the need to reproduce these results in larger-scale studies with intact plants and, ultimately, under field conditions, alongside assessments of any impacts on plant health or the native phyllosphere microbiome. The mechanisms governing phage susceptibility among bacterial strains also remain poorly understood. Meanwhile, φCB10—with its exceptional antibacterial performance, favourable stability, enormous coding capacity and potential to carry accessory functions capable of circumventing bacterial defence systems such as restriction-modification and CRISPR-Cas—stands out as a particularly compelling subject for future investigation, both as a biocontrol candidate and as a window into the biology of underexplored jumbo phages.

The research, published in the Journal of Industrial Ecology, applies a technique known as dynamic material flow analysis, or dMFA, which tracks how stocks of products and the materials embedded in them accumulate, age, and exit the economy over time. Traditional dMFA studies of electric vehicle batteries have typically assumed simplified relationships between vehicle and battery service lives—often treating the battery as dying with the car. The new framework instead integrates a product-component model that endogenously represents battery replacement, meaning that batteries can fail, be swapped, and continue cycling through the fleet independently of the vehicles that host them. The model draws on survival functions, or hazard functions, for both vehicles and batteries, allowing each to retire according to its own statistical profile.

To ground the model in reality, the researchers assembled an unusually granular dataset for British Columbia. Vehicle population figures came from the Insurance Corporation of British Columbia, while new registration data by fuel type came from Statistics Canada. The team also compiled battery electric vehicle fleet data from 2018 to 2024, including registration counts by model year, vehicle driving range, battery capacity in kilowatt-hours, energy efficiency, and cathode chemistry. Future scenarios were built from provincial population projections, evolving electric vehicle market penetration under British Columbia’s Zero-Emission Vehicles Act, and anticipated shifts in battery technology and chemistry over the coming decades.

The headline findings are striking and, in some respects, counterintuitive. Between 2025 and 2050, enhanced battery replacement could reduce the cumulative inflow of new electric vehicles needed to maintain the provincial fleet by 17 to 22 percent. The logic is that when a battery is replaced rather than the entire vehicle being scrapped, cars stay on the road longer, dampening the demand for brand-new vehicles. Yet the same dynamic increases cumulative lithium-ion battery demand by 7.2 to 7.7 percent, because each replaced battery adds a fresh unit of manufacturing demand even as vehicle production falls. Replacement, in other words, trades vehicle throughput for battery throughput.

Perhaps the most consequential result concerns what happens to batteries when they leave vehicles. The study finds that battery replacement increases the remaining useful capacity of cumulative battery outflow by 45 to 51 percent for batteries retaining at least 80 percent state of health. This is a critical threshold in the battery world: packs that still hold four-fifths of their original capacity are generally considered suitable for second-life applications such as stationary energy storage, where they can buffer renewable electricity for years before final recycling. A wave of healthier retired batteries, the authors show, materially expands the feedstock available for reuse, changing both the economics and the logistics of the battery circular economy.

Technology evolution emerges as the other powerful lever. The model indicates that, with advancements in battery technology, extending the modal battery service life by just four years could reduce cumulative material demand by 9.9 to 14.6 percent. Because lithium, nickel, and cobalt supply chains are geographically concentrated and environmentally intensive, even single-digit percentage reductions in demand translate into meaningful relief for mining pressure, processing capacity, and the carbon footprint of battery manufacturing. The result underscores a point increasingly made across industrial ecology: longevity is a materials strategy, not merely a consumer benefit.

Methodologically, the study represents a step forward in how component-level dynamics are handled in material flow models. By coupling hazard functions for vehicles and batteries, the framework captures timing effects that simpler models miss—such as the way an early battery failure in a young vehicle creates a mid-life battery demand pulse, or how improvements in battery durability shift the age distribution of retiring packs. The model also tracks the quality of outflows, not just their volume, estimating how much usable capacity exits the vehicle fleet each year. That quality dimension is what allows the researchers to quantify reuse potential rather than treating all spent batteries as equivalent waste.

The policy implications for British Columbia are immediate. The province has adopted one of the most ambitious zero-emission vehicle mandates in North America, and it operates an extended producer responsibility regime that is being extended to strengthen battery recycling. The authors explicitly position their model as a decision-support tool for the Government of British Columbia as it evaluates and calibrates its climate strategy, particularly the twin goals of accelerating zero-emission vehicle adoption and building robust battery collection and recycling systems. Knowing when, and in what condition, spent batteries will arrive is essential for sizing recycling facilities, designing collection incentives, and planning second-life storage markets.

The broader significance extends well beyond one province. Jurisdictions worldwide are grappling with the coming surge of retired electric vehicle batteries, and most forecasting exercises still rely on coarse assumptions that tie battery death to vehicle death. The British Columbia study demonstrates that this assumption can misstate both the scale and the character of future battery flows—underestimating replacement-driven battery demand, overestimating the urgency of early recycling capacity, and missing the substantial reservoir of reusable capacity in retired packs. As electric vehicle fleets mature in Europe, China, and the United States, similar product-component integrated models could become standard equipment for planners of the battery circular economy.

The study’s data and system model have been made openly available through the Queen’s University Dataverse Collection, alongside the provincial vehicle population and registration datasets on which the analysis rests. That transparency matters, because the transition to electric mobility will be judged not only on tailpipe emissions but on the full life cycle of the materials that make it possible. By revealing that battery replacement simultaneously shrinks vehicle demand, grows battery demand, and enriches the stream of reusable capacity, the research offers policymakers a more honest ledger—and a clearer map of the decisions that will determine whether the electric vehicle era is genuinely circular or simply shifts the burden from the pump to the mine.

Life expectancy at birth is one of the most widely used summary indicators of population health, capturing the average number of years a newborn would be expected to live if current age-specific mortality rates persisted throughout their lifetime. Because it condenses the entire age pattern of mortality into a single figure, it is sensitive to shifts in deaths at any age, and it serves as a powerful lens for detecting both broad public health improvements and sudden demographic shocks. The research team leveraged this sensitivity by linking two administrative data sources: the BC Vital Statistics Registry, which records all deaths among provincial residents, and the mandatory provincial health insurance program, whose enrollment files provided mid-year annual population estimates used as the denominator for mortality calculations. This linkage allowed the researchers to construct period life tables for each year of the study window and for each population subgroup of interest.

The technical backbone of the analysis was the Chiang method, a well-established statistical approach for converting age-specific death rates into abridged period life tables and corresponding life expectancy estimates. Rather than modeling individual survival, the Chiang method builds on the observed probability of dying within each age interval, chaining these probabilities across the lifespan to produce a complete life table. Because deaths were drawn from a complete registry rather than a sample, the resulting estimates describe the entire resident population of British Columbia, giving the study unusual statistical power to detect differences between small geographic and socioeconomic subgroups. The team computed annual life expectancy estimates separately for females and males, and separately across categories of urbanicity, material deprivation, and social deprivation, allowing each dimension of inequality to be examined on its own terms.

The choice of deprivation axes reflects decades of research showing that socioeconomic context shapes health through distinct pathways. Material deprivation, typically captured through indicators such as income, education, employment, and housing conditions, reflects the tangible resources available to individuals and communities. Social deprivation, by contrast, captures dimensions such as household composition, marital status, and social isolation, which influence health through support networks and social connection. By treating these two dimensions separately rather than collapsing them into a single index, the researchers could identify which form of disadvantage carried the strongest signal for premature mortality in the British Columbian context. Similarly, by stratifying by urbanicity, the analysis distinguished residents of large urban centers from those in smaller towns and rural areas, where access to health services, economic opportunity, and infrastructure can differ dramatically.

The headline result is one of divergence rather than uniform progress. Life expectancy in British Columbia rose over the 23-year study period, consistent with long-term trends in high-income countries driven by declines in cardiovascular mortality, improved cancer survival, and other incremental gains. Yet the improvements were unevenly distributed. The largest disparities appeared in rural areas and in the most deprived populations, and the gaps were especially pronounced among males. In other words, the average British Columbian gained years of life over this period, but a male newborn in a rural, materially deprived community could expect substantially fewer of those years than his counterpart in an urban, affluent neighborhood. The persistence and likely widening of these gaps over two decades suggests that the structural conditions producing them are deeply embedded rather than transient.

The study also captured the imprint of two major public health emergencies that struck the province during the study window: the illicit drug toxicity crisis and the COVID-19 pandemic. The drug toxicity crisis, which accelerated dramatically in British Columbia after 2016 as the illicit drug supply became contaminated with fentanyl and related synthetic opioids, drove sharp increases in deaths among younger and middle-aged adults, compressing life expectancy at birth in a way that few other causes can. The COVID-19 pandemic delivered a second shock beginning in 2020, with mortality concentrated among older adults and, as the analysis shows, falling disproportionately on already disadvantaged communities. The researchers found significant declines in life expectancy associated with these emergencies, but also documented resilience: life expectancy increases were observed again soon after each shock, indicating some recovery capacity in the provincial population.

That recovery, however, was not necessarily equal across subgroups. Public health emergencies of this magnitude tend to act as inequality amplifiers, because the populations with fewer resources, weaker access to care, and greater exposure to hazardous conditions absorb the mortality burden most heavily. The finding that the greatest disparities occurred among rural and most deprived populations, especially males, aligns with what is known about the epidemiology of the drug toxicity crisis, which has claimed lives overwhelmingly among men, and about pandemic mortality patterns that tracked socioeconomic vulnerability. A male newborn born into a deprived community facing both an unregulated toxic drug supply and a novel pandemic experienced compounded risks that a life table can capture in stark numerical form.

For public health planners, the study’s central message is that geography matters, but geography is not destiny. Urbanicity provides critical information about where additional public health efforts are needed, serving as a practical marker for targeting interventions, resources, and outreach to communities falling behind. Yet the authors emphasize that identifying the underlying factors, such as material and social deprivation, that contribute to health disparities may be even more valuable for reducing life expectancy inequalities. Geography tells planners where to look; deprivation tells them why the gap exists and what might be changed. A rural community that is also materially deprived faces a different set of actionable problems than a rural community that is economically secure, and policies calibrated to these distinctions are more likely to succeed than those based on postal code alone.

Methodologically, the study demonstrates the value of routinely collected administrative data for health equity surveillance. Because the vital statistics registry and insurance enrollment files cover the entire population, there is no sampling error to worry about and no survey non-response to bias the estimates. The trade-off is that administrative records describe deaths and denominators, not the mechanisms behind them; the analysis is explicitly descriptive, charting trends rather than testing causal explanations. The researchers are careful on this point, and their conclusion focuses on monitoring and targeting rather than on claims about specific interventions. Still, descriptive precision of this kind is the foundation of effective health policy: a government cannot close a gap it has not measured, and a 23-year annual series disaggregated by sex, geography, and deprivation is among the most complete measurements a province can produce.

The study was conducted as part of the work of the BC Vital Event Data Analysis Working Group, with ethics approval from the University of British Columbia Research Ethics Board, and it draws on data from hundreds of thousands of British Columbians whose deaths are recorded in the provincial registry. Each figure in the analysis represents accumulated individual losses, something the authors acknowledge directly in noting that every death in the study represents a person missed by their family and community. As British Columbia continues to grapple with the aftermath of the drug toxicity crisis, the lingering effects of the pandemic, and the long arc of socioeconomic inequality, this analysis provides a clear, quantified baseline. It shows that the province’s overall life expectancy trajectory, taken alone, conceals profound disparities, and that closing those disparities will require attention not only to where people live but to the material and social conditions in which they live. In an era when population health statistics are often reported as single provincial or national averages, this research is a reminder that averages can flatter a health system while its most vulnerable residents are left behind.

The study, published in the Journal of Emergency and Disaster Medicine, was conducted by Shannon Sherk of the University of Victoria and set out to answer two questions: what ground-level knowledge paramedics and emergency health services employees in British Columbia hold about climate hazards, and what interventions should be proposed to help pre-hospital systems adapt. The research fills a conspicuous gap. While the impacts of climate change on hospital-based clinical care have been documented extensively, the pre-hospital environment, where paramedics work in homes, on streets and along flooded highways, has been almost entirely overlooked. A recent scoping review cited in the paper concluded that no comprehensive study of strategies and solutions for pre-hospital emergency systems against climate change had yet been completed.

To gather evidence, Sherk used a mixed-methods design combining a 16-question survey with in-depth, semi-structured interviews. The survey, distributed through a British Columbia Emergency Health Service-specific Facebook group and word-of-mouth snowball sampling, ran from February 27 to March 9, 2025, and drew 109 respondents. Participants spanned all five of the province’s health regions, with Vancouver Island the most represented at 30 percent. Women comprised 54 percent of the sample, the average length of service with the ambulance service was 8.94 years, and respondents ranged from newly oriented staff to veterans with more than two decades on the road. Three interviews complemented the survey, drawing on a member of management, a union representative and a health and safety representative, all experienced paramedics.

The findings reveal a workforce that is both concerned and largely unsupported. Three-quarters of respondents believed climate change is anthropogenic, a higher proportion than the Canadian population at large, where around a third rejected human causation in 2018. More than three-quarters reported seeing a rise in climate-related hazards during their time with the service. Yet only about one in five had ever attended a climate event, workshop, protest or lecture, a disconnect the author describes as a gap between concern and educational engagement. Perceived impacts on the respondents’ own jobs scored slightly lower than perceived impacts on public health, but both were expected to worsen in the future.

Across every health region, the hazards judged most damaging to public health were the same: wildfires, in both their flames and their smoke, extreme heat, and flooding. Notably, perception did not always track mortality statistics. In 2021, fire-related deaths in the province numbered 59, while the single week of the heat dome killed more than 600. The author suggests this mismatch may indicate that slower, less quantifiable health harms, such as respiratory disease driven by smoke exposure or infectious disease linked to flooding, are being missed when systems respond only to body counts.

The interviews added texture to these numbers. All three interviewees identified hot and cold emergencies as the highest-acuity hazards. Heat deaths during the dome occurred almost exclusively indoors, while cold deaths fell primarily on people living outdoors, particularly homeless individuals whose deaths are often attributed to comorbidities such as overdose rather than exposure. Wildfire smoke emerged as a chronic threat that rarely triggers a 911 call on its own but saturates emergency departments with patients in respiratory distress, degrading capacity for the entire system. Flooding and relentless rain were linked to hypothermia and skin breakdown resembling trench foot, conditions one interviewee summarized by observing that things have gotten soggier in the last five or six years.

Paramedics themselves are far from immune. One described working the heat dome by taping bags of hospital ice to their neck and head between calls. Uniform and personal protective equipment requirements make heat harder to escape than cold, and wildfire smoke degrades respirator filters faster, raising costs and exposure. Responders described colleagues rushing from one cardiac arrest to the next during the dome, and the physical demands of the job continue regardless of air quality warnings, because, as the study puts it, no one chooses where their patient arrests. Extreme weather also severs the logistics of response: flooded roads, fallen trees and closed highways delay ambulances, strand commuting paramedics and force patients who cannot self-transport to depend entirely on ambulance service.

Perhaps the most striking statistical finding concerns politics. Consistent with earlier research, self-reported political orientation correlated with climate views in the survey. But when multiple linear regression was applied, perceived impacts on the respondents’ own jobs emerged as by far the strongest predictor of support for involving health care professionals in climate policy, with a standardized coefficient of 0.492, exceeding the next strongest variable by a margin of 0.3 and remaining significant at p less than 0.01. In other words, paramedics across the political spectrum translated lived experience of climate impacts at work into a desire for institutional action. Only five of 109 respondents rejected climate action outright.

The qualitative data exposed a workforce starved of planning. One 20-year paramedic, writing after three minor earthquakes struck in March 2025, described having no idea what the plan is for a catastrophic disaster, asking what is expected of staff on or off shift, how crews would be relieved, fed or deployed, and pleading for classroom-led rather than online training. Interviewees described management as reactionary rather than proactive, and noted that existing mental health supports rely on self-referral, leaving chronic, cumulative stress from repeated environmental emergencies unaddressed at a time when the service is already grappling with a documented mental health crisis. Interviewees also described how the decline of primary care has pushed sicker patients toward 911, compounding the load.

From these findings, the study distills a disaster-risk framework, hazard multiplied by vulnerability and exposure, divided by capacity, and derives four recommendations: commit to an organizational culture of proactivity that treats disasters as a matter of when, not if; develop region-specific hazard education and planning; integrate weather modelling and forecasting into operational management with early warnings pushed to frontline staff; and build recovery programs designed for multi-incident and chronic stress rather than single traumatic events. The author acknowledges limitations, including the self-selecting sample, the absence of a pilot phase and a scope that excluded climate mitigation topics such as electrifying the ambulance fleet. But the conclusion is pointed: for most paramedics surveyed, climate change is already harming the public, and the emergency health system absorbs that harm. Having triaged the problem, the paper suggests, the pre-hospital system can now move to treatment.
