Subject: Risk to resilience: analysing barriers to cyclone vulnerability in coastal Odisha
Keywords: Adaptation, cyclone, resilience, risk, vulnerability.
Abstract: Odisha state is situated in eastern India and has a 480 km long coastline. The coastal belt is one of the most cyclone-vulnerable regions in India. It consists of 22 community development blocks spread across six districts. Nearly one-third of the state’s total population lives in this region. Between 1891 and 2021, the state has been hit by 110 cyclones. Therefore, there is a need for a detailed assessment at the micro-level to identify cyclone vulnerability and risk. Such an assessment would help not only in planning for enhancing resilience to cyclone disasters but also in devising better strategies and adaptive measures. The major objectives of the study are (i) to identify the vulnerability and risk factors that need to be addressed at the community and household levels and (ii) to assess the status of socio-ecological resilience to cyclone vulnerability. Data for the present study were collected from primary as well as secondary sources. Two hundred and six sample households were selected from the cyclone-affected areas by using a stratified random sampling technique. Major factors that made rural households more vulnerable to cyclones were the severity of cyclone damage, income constraints, lack of banking awareness, absence of a market for selling products and loans and migration-driven labour scarcity. These findings would contribute to the understanding of the vulnerability of both space and society in coastal Odisha and thereby suggest strengthening measures to create cyclone resilience.

Subject: Ensuring long-term caprock integrity in carbon capture, utilisation and storage: a comprehensive review of geo-mechanical and monitoring approaches
Keywords: Climate change, carbon capture utilisation and storage, caprock integrity, environmental impact, geomechanics.
Abstract: Caprock integrity is essential for the successful implementation of carbon capture utilisation and storage (CCUS) technologies, which are pivotal for reducing atmospheric carbon dioxide (CO2) levels and mitigating climate change. The present study examines the role of caprock in preventing CO2 leakage, methods for assessing and ensuring its integrity and the techniques for monitoring its long-term stability. Caprock, typically composed of low-permeability materials such as shale and/or anhydrite, acts as a barrier to prevent the upward migration of CO2 from the underlying storage reservoirs. The effectiveness of caprock in preventing the leakage is determined by its physical and mechanical properties, including high porosity, low permeability, high mechanical strength and geochemical stability. Case studies from projects like Sleipner and In Salah demonstrate that effective caprock can secure CO2 for extended periods without significant leakage. Different methods are employed to ensure caprock integrity. They include laboratory testing, field experiments and geo-mechanical modelling. Core sampling and laboratory tests provide the data on caprock properties, whereas in situ stress tests and hydraulic fracturing experiments offer insights into the stress distribution and mechanical behaviour of the caprock formations. Numerical models coupled with fluid flow and mechanical deformation simulations predict the impact of CO2 injection on caprock stability. Risk assessment and mitigation strategies, such as optimising injection pressures and using chemical sealants, are essential for reinforcing the caprock integrity. The long-term stability of caprock is critical to the sustainability of CCUS projects. Geochemical models simulate CO2–brine–rock interactions, assessing the impact of geochemical reactions on caprock properties. Advanced monitoring technologies, including seismic surveys, interferometric synthetic aperture radar (InSAR) and fibre optic sensors, provide realtime data on the mechanical and chemical behaviour of caprock. Integrated monitoring programmes from projects like Weyburn-Midale and Otway highlight the importance of comprehensive monitoring and adaptive management strategies. Future research should prioritise the development of advanced models that incorporate complex geo-mechanical and geochemical interactions and enhance real-time monitoring technologies. Policy development should emphasise comprehensive risk assessments, continuous monitoring and international collaboration to ensure the safety and effectiveness of CCUS projects globally.

Keywords: Flax, bast fibre, commercial crop, linen, linseed
Abstract: Flax, or linseed, is a plant morphotype that produces commercially important linen fibre and oil respectively. The domestication history of flax is understood from the documents of various ancient civilisations. Flax cultivation eventually spread across the globe over time based on its selective products. Flaxseed and oils are recognised for their healthenhancing attributes owing to elevated contents of polyunsaturated fatty acids, including α-linolenic acid and lignans. Among its other diverse uses, flax fibre is significant in the textile industry. Research on flax is advancing in the areas of molecular genetics and breeding, genomics, and cutting-edge genetic engineering techniques, including genome editing. The breakthroughs in research and increased awareness of its natural products and health benefits may contribute to the economic development of farmers and the nation

Subject: Invasion of small hive beetle (Aethina tumida Murray 1867) in India: an emerging threat to bee health and beekeeping
Keywords: None
Abstract: Beekeeping in India is a cornerstone agro-based enterprise, intricately linked to rural livelihoods, pollination, biodiversity conservation and national food security. With over 12.26 lakh honeybee colonies and nearly 10,000 registered beekeepers, the country produces 1.25 lakh metric tonnes (MT) per year of honey annually1 . India stands as the world’s top honey-producing nation, exporting approximately 70,000 MT and generating INR 900–1,000 crore annually in foreign revenue2 . The domestic beekeeping market is valued at INR 28,794.4 million in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 9.71%, reaching INR 68,183.0 million by 2033 (ref. 3). However, this promising trajectory now faces a formidable threat. The recent invasion of small hive beetle (SHB) (Aethina tumida, Coleoptera: Nitidulidae) poses a perilous risk to India’s beekeeping landscape. This pest emerged globally as a devastating predator, parasite and scavenger of honey bee colonies. In India’s climate, SHB’s aggressive feeding habits – consuming everything from pollen and brood to honey and wax – can lead to rapid colony collapse, contamination of hive products, and large-scale economic losses. Its presence marks a looming crisis not just for honey production but for pollination services vital to Indian agriculture and ecosystem stability.

Subject: A multi-species foraging aggregation of Delphinids in Western Indian waters
Keywords: None
Abstract: Animals generally tend to form heterospecific associations for two functional advantages: more effective foraging and predator avoidance. Such interactions have been observed in different phyletic groups and between closely and distantly related species. The nature of such polyspecific aggregations is often dynamic, in which there may or may not be direct and coordinated behavioural interactions. Although the definition for mixed groups is broad, it is appropriate to consider such an association as occurring among the species of the same group. Thus, aggregations of distantly related species tend to be facilitated by concentrated resources while mixed groups of related species might occur irrespective of prey concentration1 . In the marine realm, multispecific aggregations and interactions are known to occur especially between the marine mammals, fishes and seabirds as part of foraging.

Abstract: Neurocognitive development is a mental process of acquiring knowledge and understanding through thinking, perception, sensory experience and also effective response. The preschool years are the years of blossoming in the brain. In the first year of life, a million neuronal connections are made per second. The synaptic density reaches its peak during the third year of life. Hence, the 1000 days after birth are the most important for neurocognitive development. The neurocognitive phenotype always co-exists with any developmental motor abnormality.

Keywords: Agromet Advisory, climate risk management, forecasts, South Interior Karnataka.
Abstract: Climate risk management in rainfed regions entails forecasting, impact assessment and relief planning, with emphasis on timely forecast dissemination and accurate loss estimation. Under the Gramin Krishi Mausam Sewa initiative, the India Meteorological Department issues agro-meteorological advisories, evaluated using qualitative, quantitative and statistical methods. In the present study on South Interior Karnataka, the forecast accuracy was higher for temperature (75–79%) than for wind speed and rainfall. Ramanagara showed the best rainfall forecast performance. Statistical tests (Hanssen–Kuipers, Kolmogorov–Smirnov, Anderson–Darling) revealed spatial variability, influenced by orography. Taylor diagram analysis confirmed good agreement between observed and forecasted temperatures (0.7–0.8 for maximum temperature, 0.6–0.7 for minimum temperature), indicating reliable temperature forecasts.

Abstract: The present study investigates heavy rainfall patterns and their variability in Ladakh by using K-means clustering with the Apriori algorithm, which uncovers the co-occurrence pattern of heavy rainfall alerts obtained from the ISRO MOSDAC portal. The proposed algorithms reveal that location (lat.: min. = 32.82, max. = 35.71; long.: min. = 77.59, max. = 79.91) and location (lat.: min. = 33.11, max. = 35.76; long.: min. = 75.82, max. = 77.75) exhibit the highest confidence (79.55%) and frequency (48.61%) among all patterns, indicating strong interdependencies. This suggests that the alerts in one location can potentially impact the other, offering actionable guidance for disaster preparedness. The present study highlights a significant match between predicted alerts and actual heavy rainfall events, underscoring the utility of machine learning in refining weather alert systems.

Keywords: Bacillus tequilensis, gluten intolerance, health supplements, Oreochromis niloticus, probiotic
Abstract: Gluten intolerance can be recognised as an emerging health concern. Currently, there are few, if any, medications available to mitigate gluten intolerance symptoms, prompting the search for effective natural alternatives. Recent studies have demonstrated the significant potential of probiotic bacteria that hydrolyse gluten in alleviating symptoms of gluten intolerance. This study aims to evaluate the gluten-hydrolysing ability of five bacterial isolates from Tilapia (Oreochromis niloticus) and assess their in vitro probiotic attributes. Biochemical and molecular characterisation identified the isolates as Bacillus licheniformis (L1), Bacillus tequilensis (G1), Lactococcus lactis (G5), Enterococcus faecium (G7) and Weissella confusa (G9). All isolates were capable of surviving a wide pH range (3–9) and exhibited surface hydrophobicity and auto-aggregation properties. Furthermore, according to Clinical and Laboratory Standards Institute (CLSI) criteria, the isolates were susceptible to most of the tested antibiotics. The study concludes that the five isolates from Tilapia can hydrolyse gluten and possess essential probiotic properties, suggesting their potential as probiotic supplements for individuals with gluten intolerance.

Abstract: The present study depicts the tail fin design, realisation, and propulsion performance of the biomimetic robofish prototype utilising the carangiform motion for efficient two-dimensional (2D) propulsion. Lighthill’s 2D waving plate theory and MATLAB simulations are used to optimise the thrust by varying link and joint configurations. The two-link design achieves a speed of one knot in forward and reverse using a 12 V, 7 Ah battery and servo motor with pulse-width modulation. The robofish is onboard programmed with a timed sequence actuation for forward and downward manoeuvring. An experimental validation in the test tank confirms its performance, showing its potential for advancing bio-inspired underwater propulsion systems

Abstract: Diabetic kidney disease (DKD), which is defined as chronic kidney disease in a person with diabetes, is one of the severe complications of diabetes, leading to end-stage kidney disease. According to the International Diabetes Federation report on diabetes and kidney disease, there is a 74% increase in the incidence of chronic kidney disease due to diabetes between 1990 and 2017 worldwide, and India stands third in possessing the highest number of incident cases. To tackle the huge burden of morbidity and mortality related to DKD, it is important to detect it early and manage it effectively. Albuminuria and estimated glomerular filtration rate are conventionally used to detect DKD. Some of the limitations associated with them in terms of early detection can be met by the discovery of novel biomarkers for DKD. Integration of multiomic markers discovered through genetic, epigenetic, transcriptomic, proteomic and metabolomic studies for DKD holds potential to identify better markers for DKD prediction and progression. The present review article aims to emphasise the burden of DKD and the need to find biomarkers for early detection, which will aid in targeted prevention of the onset and progression of D

Subject: Groundwater quality in Eastern Karnataka, India – an end-use analysis
Keywords: Agriculture, drinking, end-use, geochemistry, groundwater, industry.
Abstract: Physico-chemical characteristics of groundwater in parts of Eastern Karnataka are examined to determine whether they conform to the quality standards of water used for drinking, agriculture and industrial end uses. Eighty eight samples from forty five villages have been analysed for this purpose. Cation abundances in the groundwater are in the order: Na+ > Ca++ > Mg++ > K +. Anion abundances are in the order HCO− 3 > Cl− > SO2 4 > NO− 3 > F −. Only in one locality, SO2 4 content is very high. According to Piper’s classification, 42% of the water samples belong to Ca–Mg–Cl type; 30% to the Ca–Mg–HCO3, 16% to Ca–Na–HCO3, 9% to NaCl and 3% to NaHCO3 types. Gibbs plot shows that water–rock interaction is the dominant process controlling the major ion chemistry, although there is evidence of evaporation at some places. Out of 45 villages, excess of fluoride, nitrate and uranium are found in 23, 28 and 26 villages respectively. Phosphate is higher than 1 mg/l in all the villages. Lithium exceeds the permissible limit in 27 out of 43 localities. Concentrations of other trace elements Ag, Al, Ba, Tl, As, B, Co, Cr, Cu, Fe, Li, Mn, Ni, Pb, Se, V, Zn and U were determined in selected samples. Arsenic exceeds the permissible limit for drinking water in one village. Groundwater in 21 out of 45 villages is suitable for agriculture, while groundwater of 31 villages is useful for some industries.

Keywords: None
Abstract: Mountains are critical to human wellbeing and biodiversity, supporting rich ecological communities, including many endemic species . To protect these ecosystems, approximately one-third of the world’s mountainous regions have been designated as protected areas . The Shivalik mountain range, also known as SubHimalaya or Outer Himalaya, runs parallel to the Lesser Himalaya . To protect this landscape, especially in its North-West part, 21 protected areas have been established across six states and one union territory, covering nearly 2,500 sq. km (ref. 4). Among them, Shilli Wildlife Sanctuary, located in Solan district of Himachal Pradesh at an altitude of 1200–1800 m, was established in 1963 for in situ conservation of wildlife3 .
