										<content:encoded><![CDATA[<p>Underwater robotics and diving equipment face a brutal reality: damage happens, power is hard to replace, and most sensors fail permanently when punctured. A single tear in an underwater electronic skin can end communication, navigation, and grip control—turning repair into an after-the-fact safety problem rather than an onboard capability.</p>
<p>Now, researchers at the National University of Singapore (NUS) have created a self-healing magnetoelectric sensory system (SMES) designed to sense touch and nearby objects while also detecting damage and repairing itself. The system is engineered as a layered structure that combines a top damage-sensing layer with an electromagnetic sensing layer, both built on a stretchable, self-healing elastomer infused with liquid-metal conductors.</p>
<p>The “pain sensing” concept is central. When the outer layer is pricked, punctured, or cut, its electrical resistance sharply increases, providing immediate electrical feedback that the material has been harmed. That same design enables recovery: the elastomer uses reversible molecular interactions so that once damaged surfaces are brought into contact again, the material reconnects and regains function. After needle-level injuries, performance returns within seconds; after more severe cuts, brief mechanical pressure initiates repair and full restoration follows over time.</p>
<p>Crucially, healing and sensing continue even underwater, where many materials struggle to re-bond. The elastomer achieves up to 92% elastic recovery and—after mild heating—can reach roughly 82% healing efficiency in air after seven days and nearly complete recovery in water after 10 days. Sensors retain damage detection and self-repair capabilities when fully submerged, an essential requirement for reliable marine operation.</p>
<p>SMES is also self-powered. Instead of relying on batteries, it generates electrical signals via electromagnetic induction: a magnet shifts relative to a liquid-metal coil when an object approaches or presses the sensor, inducing a voltage that supports both proximity sensing and tactile sensing. This approach reduces power dependence, a major advantage for long-duration underwater missions.</p>
<p>In tests, the system responded in about 41 milliseconds—fast enough for real-time control—and produced stable output across 10,000 cycles. Proximity sensing remained consistent after 10 days of underwater immersion, including in simulated seawater.</p>
<p>To prove real-world value, the team built two prototypes. A smart diving glove translates fingertip touch events into wireless gestures for underwater communication, while damage alerts can be displayed instantly via LEDs when severe punctures occur. A robotic hand integrates the SMES for underwater grasping and transport tasks, monitoring structural damage and recovering from punctures caused by sharp shell-like impacts.</p>
<p>Published in <em>Advanced Materials</em> on 18 April 2026, the technology points toward electronic skins and soft robotics that can autonomously recognize injury, begin healing immediately, and operate reliably in unpredictable aquatic environments—closer to living skin than conventional electronics.</p>

										<content:encoded><![CDATA[<p>Rivers can act like living scrubbers for methane, a greenhouse gas far more potent than carbon dioxide over shorter timescales. New research from the University of Liège shows that this microbial methane “filter” varies sharply across continents—and, crucially, it may not be strong enough to counteract the methane surge expected as the climate warms and river chemistry changes.</p>
<p>The study focuses on the tug-of-war inside riverbeds: methane production through methanogenesis versus methane loss through microbial oxidation. In methanogenesis, microorganisms generate methane as a metabolic end product from organic matter in sediments and soils. In methane oxidation, specialized microbes consume methane, using it to build biomass or harvest energy, potentially preventing some emissions from reaching the atmosphere.</p>
<p>To test how effective this process really is, Alberto Borges and colleagues conducted a comparative field study in Belgium and across river systems in Africa. Their results show that microbial methane oxidation is consistently more significant in African rivers than in Belgian ones, pointing to environmental and biological controls on the microbial community responsible for consuming methane.</p>
<p>In Belgium, the oxidation signal was weaker, especially in portions of rivers affected by riverbank development. The researchers argue that engineered banks reduce the transfer of microbial communities and organic substrates from surrounding soils into the flowing water and sediments where oxidation would occur.</p>
<p>Another driver appears to be invasive filtration by Asian corbicula, a bivalve known to alter river food webs and physical transport. By changing how particles and microorganisms are filtered and distributed, this species can interfere with the conditions that support methane-oxidizing microbes.</p>
<p>The work also reveals a critical pattern upstream: headwater rivers exhibit very low methane oxidation. Despite their disproportionate contribution to total river-to-atmosphere methane emissions, these small systems provide limited biological mitigation.</p>
<p>Taken together, the findings suggest that even if climate change and nutrient pollution enhance methane production, microbial oxidation is unlikely to scale up enough to compensate. Human disruptions—habitat alteration and invasive filter-feeders—may further erode the natural capacity of rivers to curb methane emissions.</p>
<p>The researchers conclude that methane mitigation strategies cannot rely on rivers’ microbial filtration alone. Instead, they call for understanding how land use, connectivity with wetlands, and ecosystem perturbations control the methane cycle at fine spatial scales—especially in headwater networks.</p>

										<content:encoded><![CDATA[<p>The 2026 Ecological Society of America (ESA) Annual Meeting will be held in Salt Lake City, Utah, July 26–31, bringing thousands of researchers together to report how wildlife is responding to rapid environmental change. Across terrestrial, freshwater, and marine systems, teams will present emerging results on ecological relationships among animals, habitats, and the expanding footprint of human activities. For the first time, the meeting’s press coverage will emphasize high-throughput field approaches—ranging from long-term monitoring to animal-borne sensors—that help link ecosystem shifts to measurable biological outcomes.</p>
<p>Featured talks and posters spotlight predator recovery and its cascading effects, documented declines in vulnerable taxa, and rewilding experiments that test ecological resilience. Researchers will also tackle wildlife disease dynamics, including how outbreaks can emerge and spread in complex environments. Sessions cover animal behavior and human-wildlife interactions, with attention to factors such as roads, habitat development, anthropogenic noise, and anthropogenic heat.</p>
<p>The program ranges from megafauna to small, conservation-critical species. Studies include how elephant carcasses can alter soil chemistry and downstream plant physiology, seeding success, and herbivory patterns across savannas. Other contributions examine persistent vegetation decline following large-carnivore restoration in northern Yellowstone, testing whether trophic recovery can stabilize plant communities over time. In freshwater systems, researchers will report on endangered suckers nearing extirpation in Upper Klamath Lake, where monitoring context is essential for identifying thresholds for recovery.</p>
<p>Marine and coastal research will highlight multi-decadal surveillance for avian influenza linked to marine mammals, using years of observational data to interpret outbreak timing and ecological connectivity. Additional work examines how salmon carcasses deliver marine-derived nitrogen that reshapes soil microbial communities in temperate rainforests. Together, these studies illustrate how cross-ecosystem subsidies can reorganize ecological networks.</p>
<p>Urban ecology sessions will explore the behavioral consequences of domestic cats and dogs on wildlife movement patterns, using spatial and temporal analysis to quantify risk. Global-change research also appears in work assessing how shoreline development influences nesting habitat selection in common loons, providing a measurable bridge between land use and reproductive outcomes.</p>
<p>Conference attendees can register free as media participants, and ESA press resources will offer access to scientific sessions plus a dedicated press room with internet, printing, and interview space. ESA invites eligible journalists and institutional communications staff to coordinate through its media contact and credential policy.</p>

										<content:encoded><![CDATA[<p>A new open-access study in <em>Biological Diversity</em> challenges a comforting assumption in Baltic coastal monitoring: that mesozooplankton communities are broadly uniform across space. Instead, researchers report sharp fine-scale differences among three brackish bays in the Central and Eastern Baltic Sea—differences so pronounced they emerge over sub-kilometre distances.</p>
<p>Led by Neele Schmidt and Amanda Adam Jansson at Uppsala University, the work links community turnover to local hydrography. Salinity and temperature, the authors argue, act as primary environmental filters that reshape which plankton taxa dominate at a given site, both between separate bays and within individual embayments.</p>
<p>Field sampling took place in June 2022 across Baggensfjärden, Kappelshamnsviken, and Tvären. At each bay, scientists deployed a 100 μm WP2 closing net to collect vertically integrated mesozooplankton samples (&gt;200 μm), using three replicate stations to capture within-bay variability.</p>
<p>To anchor biological patterns to physical drivers, hydrographic profiles of temperature and salinity were recorded with multiparameter probes at the deepest point of each bay. In the laboratory, preserved samples were identified taxonomically and standardized as abundance per cubic metre, enabling quantitative comparisons across stations.</p>
<p>Statistical analyses used nonmetric multidimensional scaling (NMDS) with Bray–Curtis dissimilarity, alongside diversity metrics calculated in the vegan framework. This approach revealed community separation consistent with environmental gradients rather than simple spatial averaging.</p>
<p>Between-bay contrasts were especially clear. Kappelshamnsviken, the more marine bay with deep-water salinity reaching about 9, carried high densities of calanoid copepods such as <em>Pseudocalanus</em> sp. and <em>Temora</em> sp., and showed the highest Shannon–Wiener diversity and evenness.</p>
<p>By contrast, lower-salinity systems—Tvären and Baggensfjärden—were rotifer-dominated. Tvären recorded the highest total zooplankton abundance (46,241 ± 25,941 ind/m³) but also the lowest evenness, indicating that one taxon disproportionately structured the community.</p>
<p>Within individual bays, assemblages changed dramatically over less than 1 km. Deeper stations favored <em>Pseudocalanus</em> sp., while shallow zones were more likely to host cyclopoid copepods and branchiopods, suggesting that stratification and local mixing regimes create ecological microhabitats.</p>
<p>The results carry practical consequences for fisheries and conservation. If zooplankton communities are patchy at fine scales, then sparse sampling can miss key ecological niches and misrepresent ecosystem health signals, including responses to eutrophication and climate change.</p>
<p>To generalize across seasons, the authors call for multi-season sampling and broader tracking of environmental variables. Their findings align with the Essential Ocean Variable (EOV) perspective, emphasizing that coastal monitoring designs must be dense enough to resolve real biological heterogeneity.</p>

										<content:encoded><![CDATA[<p>Sea levels rise as Earth warms, and with that comes a less obvious threat to freshwater ecosystems: saltier water. MIT researchers report that increasing salinity can reshape the microbial communities that drive key biogeochemical processes in rivers, estuaries, and coastal-adjacent waters.</p>
<p>Microbes are central to the carbon cycle, including the decomposition of organic matter such as algal biomass. In this study, the team asked what happens to these communities when they experience salt concentrations that mimic seawater intrusion.</p>
<p>Using microbial samples from three environments spanning a wide salinity gradient—including the Charles River (4 g/L), Boston Harbor (30 g/L), and a Massachusetts beach near Nahant (35 g/L)—the researchers cultivated each community across three new salinity conditions (16, 31, and 46 g/L) for two weeks.</p>
<p>Across all conditions, the communities sustained roughly the same overall growth rate, suggesting that total biomass accumulation can remain surprisingly resilient. However, community composition shifted sharply, with higher-salinity exposures reducing diversity as a subset of strains grew faster and took over.</p>
<p>The results indicate a classic ecological tradeoff: salinity stress may not immediately suppress growth, yet it can reorganize the ecosystem toward fewer, more competitive microbial types. “At higher salinity, you lose diversity,” the lead author Jana Huisman notes, while emphasizing the unexpected stability of growth and biomass production.</p>
<p>To test whether the laboratory pattern matches real-world systems, the researchers analyzed publicly available genomic datasets from aquatic environments such as the Chesapeake Bay, Gulf of Mexico, and Baltic Sea. They used the 16S rRNA gene copy number as a proxy for intrinsic maximum growth potential.</p>
<p>In these natural communities, higher-salinity habitats also tended to be dominated by faster-growing species, mirroring the lab findings and strengthening the case that salinity-driven selection is a recurring ecological force.</p>
<p>The study also raises concerns about downstream vulnerability. If diversity declines, microbial communities may become less able to withstand additional environmental pressures, even if their short-term growth rate appears intact.</p>
<p>Finally, the researchers did not map the specific functional roles of the strains that expand under salt stress. Some fast growers could enhance ecosystem performance, while others might include harmful pathogens—an open question for future work.</p>

										<content:encoded><![CDATA[<p>Human pressure is reshaping coral reefs at the chemical level, according to a new study led by the University of Hawai‘i at Mānoa and published in <em>Nature Communications</em>. Researchers report that a suite of 25 contaminants—sourced from agriculture, industry, and pharmaceuticals—accumulates in the soft tissues of corals near Maui, Hawai‘i. Alongside this chemical intrusion, the same coastal sites show a measurable decline in the coral’s internal nutrient and energy reserves. The result is a lower capacity to withstand environmental stressors such as heat and ocean acidification.</p>
<p>To uncover these hidden changes, the team used coral metabolomics, effectively reading the “metabolome” stored inside coral tissues. Lead author Zachary Quinlan, a researcher at the Hawai‘i Institute of Marine Biology, says metabolome monitoring could become a practical way to track anthropogenic damage before it is visible in traditional reef metrics.</p>
<p>The study analyzed metabolomes from 380 lobe corals (<em>Porites lobata</em>) and rice corals (<em>Montipora capitata</em>) across 16 locations off west and south Maui. Importantly, the researchers compared sites with different degrees of human influence, spanning both impacts originating from land-based watersheds and changes occurring within the marine ecosystem itself.</p>
<p>Across species, human activity altered the metabolic composition of coral tissues. In more disturbed areas, contaminants increased while nitrogen and energy-related compounds decreased, indicating that corals may be reallocating internal resources under chronic chemical and environmental pressure.</p>
<p>Quinlan highlights a striking pattern: despite the two coral species having distinct life strategies, both showed nearly identical metabolome trends. The consistency suggests that anthropogenic forcing may be strong enough to impose similar physiological signatures across different coral types.</p>
<p>The team also connected current chemistry to reef history. Using coral-cover trends from five sampling sites following the severe 2016 bleaching event, they found that locations with the greatest post-bleaching declines exhibited the most impacted metabolomes. There, nitrogen and energy reserves were reduced, while stress-associated chemicals were enriched.</p>
<p>Two mechanisms were proposed. First, accumulated anthropogenic molecules—including pharmaceuticals and industrial byproducts—may directly stress coral physiology. Second, increased human-driven environmental demands could force corals to spend nitrogen and energetic resources that would otherwise support recovery after heat and carbonate chemistry stress.</p>
<p>Overall, the findings position coral metabolomes as a sensitive diagnostic for ecosystem disturbance and contaminant escape into coastal environments. The study underscores the urgency of reducing human impacts to protect both marine resilience and human health, and it points toward controlled experiments aimed at boosting coral nitrogen and energy reserves.</p>

										<content:encoded><![CDATA[<p>An international research team led by the University of Barcelona has identified a major, previously underestimated driver of Early Holocene environmental change across the Eastern Mediterranean: a large, low-salinity outflow from the Black Sea into the Aegean Sea. Occurring roughly between 11,000 and 6,000 years ago, this freshwater pulse helped reshape regional circulation more profoundly than earlier models had suggested.</p>
<p>The study, published in <em>Communications Earth &amp; Environment</em> (published 20-Jun-2026), shows that Black Sea freshwater strengthened surface-water stratification in the Aegean. When the upper ocean became more layered, the formation of deep waters was suppressed—an oceanographic shift that strongly affects how nutrients and organic matter are transported and preserved.</p>
<p>A key outcome of this altered circulation was the development of <em>Sapropel 1</em>, a widespread organic-rich sediment layer deposited across the Eastern Mediterranean during the Early Holocene. The researchers argue that the Black Sea outflow provided a critical mechanism, helping create conditions favorable for organic material to accumulate on the seafloor.</p>
<p>For decades, explanations for Sapropel 1 emphasized increased freshwater delivery from North African rivers and enhanced precipitation over the northern Mediterranean region. The new results challenge that view by demonstrating that the Black Sea drainage basin itself acted as a powerful freshwater source, capable of reorganizing water masses through the Dardanelles Strait.</p>
<p>The researchers connect intensified meltwater input and wetter conditions across the Black Sea basin to stronger export of low-salinity water. This reorganization occurred in the northern and central Aegean Sea, changing the balance between stratification and deep-water convection during a warm climatic interval.</p>
<p>To reconstruct these processes, the team analyzed a marine sediment core from the central Aegean Sea near important deep-water formation areas in the north. The archive spans more than 42,000 years, enabling comparisons of long-term variability with the specific environmental transition linked to the Early Holocene.</p>
<p>They combined multiple advanced techniques—grain-size analysis, X-ray fluorescence scanning, radiogenic isotopes, and stable isotope geochemistry—to distinguish the fingerprint of Black Sea outflow from other climatic and hydrological signals.</p>
<p>Beyond reconstructing the past, the findings provide a “stress test” for future climate scenarios. If large freshwater inputs can disrupt deep-water formation and reorganize circulation in warm periods, similar mechanisms could influence marine ecosystems and carbon burial under ongoing climate change.</p>

										<content:encoded><![CDATA[<p>Researchers from Heinrich Heine University Düsseldorf (HHU) and Kiel University (CAU) have uncovered a surprising ability in an early-branching animal: a sea anemone can discriminate between different microbes and thereby protect beneficial bacteria while targeting harmful strangers. The work, published in <em>Nature Communications</em>, challenges a long-standing view that selective microbial recognition belongs only to vertebrates.</p>
<p>The study focuses on innate immunity in <em>Nematostella vectensis</em>, which lacks antibodies and adaptive immune memory. Instead, the researchers examined “nematosomes,” motile multicellular units inside the organism that patrol and respond to microbes in the surrounding environment. These structures function as cellular actors for the animal’s first-line defense.</p>
<p>Using functional experiments, the team showed that nematosomes preferentially engulf and break down non-native bacterial strains, while largely sparing bacteria that naturally form the anemone’s own microbiome. This selective phagocytosis supports a stable microbial community—one that benefits the host rather than disrupting it.</p>
<p>A central molecular regulator emerged from the experiments: the cJun gene. The researchers used CRISPR/Cas to switch off cJun, effectively disabling a key control mechanism for nematosome behavior. The modified animals produced fewer nematosomes than controls.</p>
<p>Most importantly, the cJun-deficient sea anemones lost reliable discrimination between foreign and self-associated bacteria. As a result, microbial balance shifted, and the animals became more susceptible to bacterial infections, linking gene-controlled cell behavior to ecosystem-level host protection.</p>
<p>Lead author Dr Nida Kaya emphasizes the evolutionary implication: “Targeted identification of microorganisms is not a privilege restricted to the adaptive immune system.” The findings indicate that invertebrates can still execute refined, microbiome-aware immune strategies despite relying on innate mechanisms alone.</p>
<p>Professor Sebastian Fraune further argues that selective recognition may be far older than previously assumed. By showing how early animals balanced beneficial microbes and pathogens for hundreds of millions of years, the study reframes the evolutionary origins of immune sophistication.</p>
<p>The results also revive interest in “trained immunity” or innate immune memory—processes by which prior microbial encounters can enhance later responses without adaptive antibodies. The nematosomes described here offer a tractable cellular system for probing the signaling pathways that underpin such responsiveness.</p>
<p>Beyond basic immunobiology, the work suggests practical research directions for understanding how selection at the cellular level maintains metaorganism stability—host plus microbiome as a functional unit. Future studies can map the molecular circuitry downstream of cJun to determine how closely related bacterial strains are distinguished.</p>

										<content:encoded><![CDATA[<p>Hydrothermal vents, scattered across the seafloor like isolated oases, host ecosystems that thrive on chemistry rather than sunlight. Yet many of the creatures living there are surprisingly similar—even when vents lie hundreds to thousands of kilometers apart. A long-standing puzzle has been how tiny, often non-swimming larvae can travel between these widely separated habitats. Researchers from the University of Tokyo now report evidence that sheds light on the migration routes connecting vent populations.</p>
<p>The team focused on vent-dwelling limpets (gastropods) that can retain their early larval shells after settling. Those shells, though less than a millimeter in size and extremely thin, preserve chemical “growth-ring” information. By analyzing these retained larval shell materials, the scientists reconstructed the temperature conditions the larvae experienced during development.</p>
<p>Their approach is based on the principle that the chemical signatures locked into a shell correlate with the environment in which the larva grew. The researchers converted those chemical records into temperature estimates, then used the results to infer larval life histories—effectively reading a microscopic environmental diary.</p>
<p>The findings indicate that limpets collected from deep-sea hydrothermal vents had spent their larval stage in the sunlit upper ocean (the euphotic zone). In other words, before either returning to their natal vent or establishing themselves elsewhere, the larvae likely rose from vent depths into surface waters. This supports the idea that strong currents and surface-region conditions can act as dispersal highways for vent species.</p>
<p>The study also highlights why successful migration may be rare. Larvae face major risks while adrift at the surface, from predators and unfavorable transport that could prevent them from ever reaching a suitable vent. Such bottlenecks could help explain why many vent animals produce large numbers of offspring.</p>
<p>The results further suggest that ocean temperature patterns—shaped by regional climate and water-column structure—could influence larval connectivity. Although direct evidence linking current climate change to larval dispersal is still limited, the mechanism identified here provides a plausible route by which environmental shifts could alter vent ecosystem links.</p>
<p>While the larval duration for most vent species remains unknown, experiments and related data suggest that at least some species may remain near the surface for over a year. The longevity increases both dispersal potential and exposure to threats, emphasizing the delicate balance between survival and spreading.</p>
<p>Looking ahead, the researchers plan to test how widespread this surface migration behavior is across hydrothermal vent animals, including species living deeper than about 2,000 meters. They also aim for higher-resolution chemical measurements that could trace not only the ascent to the surface but potentially the full return journey to the deep sea.</p>

										<content:encoded><![CDATA[<p>Atlantic tarpon are known for epic migrations along the Gulf and Atlantic coasts, yet the question of where they reliably find food during those journeys has largely stayed unanswered. A new University of South Florida–led study now maps the feeding geography that makes migration possible, turning a long-distance mystery into a set of identifiable biological “fuel stations.”</p>
<p>Researchers combined five years of electronic tracking with chemical signals preserved in tarpon tissues. Electronic tagging helped reveal movement, behaviors, and migration routes, while tissue chemistry offered a biological record of likely feeding locations over different time scales. By integrating these independent datasets, the team could infer not only where fish traveled, but where they most likely obtained energy.</p>
<p>The study, published in <em>Movement Ecology</em>, challenges the idea that tarpon feed randomly across their range. Instead, the results support a model in which tarpon concentrate their feeding in discrete foraging landscapes—regionally distinct habitats that repeatedly supply productive conditions during annual movement.</p>
<p>Three major feeding regions stood out: South Florida, the northern Gulf of Mexico, and the Mid-Atlantic coast. South Florida was especially important because it was used consistently across multiple migratory groups, suggesting it functions as a recurring anchor point within the broader migration network.</p>
<p>Using samples from 417 tarpon and linking them to 85 acoustically tagged fish, the researchers estimated that the most probable foraging areas are often hundreds of kilometers from capture sites. On average, likely feeding locations were about 300 kilometers (185 miles) away, highlighting how coastal fisheries may depend on habitat conditions far from where anglers take their catch.</p>
<p>Short-term blood chemistry reflected more recent, local feeding, while longer-term fin-clip tissues integrated feeding signals across several months. This temporal layering helped the team distinguish near-term foraging from broader migration-associated feeding patterns.</p>
<p>The conservation implications are immediate. If migration depends on a limited set of productive regions, then habitat loss, altered freshwater flows, coastal development, or climate-driven change can weaken tarpon populations across entire coastlines, not just in isolated hotspots.</p>
<p>Beyond tarpon, the authors argue that the framework can be adapted to other migratory marine species whose feeding grounds are difficult to observe directly. Identifying where energy comes from is a prerequisite for protecting the ecosystems that sustain both biodiversity and sustainable recreational fisheries.</p>
