The synergistic impact of Spirulina and Sulfate reducing bacteria on lettuce growth in Cadmium contaminated soil
Abstract Cadmium (Cd) contamination is a critical environmental issue, adversely affecting plant growth and agricultural productivity. While numerous studies have explored the role of various bacteria in mitigating heavy metal toxicity, the specific impacts of sulfate-reducing bacteria ( Desulfovibrio desulfuricans , SRB) and the cyanobacterium Spirulina ( Arthrospira platensis , SP), both individually and in combination, on Cd-contaminated plants remain underexplored. This study investigates the effects of SRB and SP on lettuce plants exposed to Cd contamination, aiming to enhance our understanding of their potential in alleviating Cd toxicity and promoting plant health. Results revealed that Cd contamination significantly reduced root growth in all treatments except for the combined application of SRB and SP. This combination also led to a marked decrease in leaf Cd content and improved leaf area, particularly under Cd stress. Furthermore, SP and SRB together increased the relative water content in contaminated soils, and SRB alone induced hydrogen peroxide production in non-contaminated soils. The co-application of SRB and SP significantly boosted catalase and superoxide dismutase activities, enhancing photosynthetic capacity and overall plant growth under Cd stress. These findings underscore the promising potential of using SRB and SP synergistically to mitigate Cd-induced challenges in lettuce cultivation, offering a viable strategy to improve crop productivity in contaminated environments.

Adaptive evolution and early diversification of photonic nanomaterials in marine diatoms
Abstract The discovery of natural slab photonic crystals in diatoms has sparked questions regarding their prevalence and functional role in nature. These advanced nanomaterials open so-called photonic stopbands in two dimensions, enabling precise light manipulation essential in technologies like quantum computing and photonics. However, the natural role of these advanced properties remains a mystery. In this study, we adopted a multidisciplinary approach, combining taxonomic, evolutionary, and photonic property analyses. Using scanning electron micrographs, we examined the girdle elements of the silicon dioxide shell from several hundred diatom species to explore the potential correlation between occurrence of slab photonic crystals and taxonomic relationship. Girdle slab photonic crystals emerged among the oldest diatom classes, with stopband properties covering the visible to mid-infrared spectral range. Square lattice formations emerged first, evolving from quasi-ordered templates, and later diverged into more efficiently packed hexagonal structures. This study shows how photonic nanomaterials developed from quasi order to order over evolutionary trajectories and provides a sustainable inventory of natural slab photonic crystals for application and deeper investigation. Understanding how diatoms utilize these structures can inspire innovative principles for smarter energy management systems as well serve as a model for the evolution of order and symmetry in cellular processes and organization.

Perinatal obesity primes the hepatic metabolic stress response in the offspring across life span
Abstract Perinatal obesity is associated with an increased risk of metabolic diseases and hepatic dysfunction in offspring. However, the underlying mechanisms of this metabolic programming remain incompletely understood. This study aimed to elucidate the influence of maternal obesity and early life exposure to high-fat diet on offspring liver phenotype, hepatokine profile, and key components of hepatic metabolism. To this end, we employed a murine high-fat diet-induced perinatal obesity model, investigating the offspring in early life and late adulthood. After exposure to perinatal obesity, the offspring showed a significantly increased body weight in early life with no histological signs of steatosis, but a dysregulated hepatokine profile. Proteomic profiling, followed by molecular analyses, revealed a decreased lipogenesis and increased fatty acid oxidation, suggesting a protective mechanism against the development of steatosis. These changes were accompanied by increased markers of lipid peroxidation and DNA damage, indicating increased oxidative stress. Concomitantly, the antioxidative enzymes catalase and superoxide dismutase 2 were significantly reduced and oxidative phosphorylation was impaired, implying an altered oxidative stress response. While changes in oxidative stress level were only detected in early life, the lipid metabolism was altered across life span. This metabolic programming could determine the resilience and susceptibility to chronic liver disease later in life.

Discharge distribution in a multi-outlet spillway with varying adverse conditions
Abstract Hydropower and dam structures worldwide are facing evolving requirements due to changes in climate, better methods for flood estimates, combined with the needs of surrounding interests. Improved understanding of the hydraulic behavior of spillways, and the approach flow leading up to them, is important for evaluation of existing spillways and considering potential redesigns. There is limited research on the distribution of flow across a multiple outlet spillway, therefore a purpose built experimental setup is utilized to examine the impact of various geometrical changes on the flow distribution across a spillway with three outlets. The maximum difference measured between the different outlets were as much as 10%. While small changes to abutment and pier corners were found to reduce total discharge capacity up to 8%, with increased discharge and overflow height causing greater reduction in the capacity of the spillway. To further investigate the flow behavior leading up to the spillway outlets, ADV measurements were conducted to capture flow velocities. The measured flow cross sections indicate a stable flow field leading away from the inlet, stagnation zones and recirculation zones leading up to the spillway, with minor variations occurring for increasing inlet flow rates.
