Background: In response to iron deficiency and other environmental stressors, cyanobacteria producing siderophores can help in ameliorating plant stress and enhancing growth physiological and biochemical processes. The objective of this work was to screen the potential of Arthrospira platensis, Pseudanabaena limnetica, Nostoc carneum, and Synechococcus mundulus for siderophore production to select the most promising isolate, then to examine the potentiality of the isolated siderophore in promoting Zea mays seedling growth in an iron-limited environment.
Results: Data of the screening experiment illustrated that Synechococcus mundulus significantly recorded the maximum highest siderophore production (78 ± 2%) while the minimum production was recorded by Nostoc carneum (24.

With the growing need for precise campus electricity management, understanding load patterns is crucial for improving energy efficiency and optimizing energy use. However, detailed electricity load data for campus buildings and their internal equipment is often lacking, hindering research. This paper introduces an energy consumption monitoring dataset from The Hong Kong University of Science and Technology (HKUST) campus in Hong Kong, comprising data from over 1400 meters across more than 20 buildings and collected over two and a half years.

The COVID-19 pandemic has profoundly impacted global economies and healthcare systems, revealing critical vulnerabilities in both. In response, our study introduces a groundbreaking method for the detection of SARS-CoV-2 cDNA, leveraging Luminescence resonance energy transfer (LRET) between upconversion nanoparticles (UCNPs) and gold nanoparticles (AuNPs) to achieve an unprecedented detection limit of 242 femtomolar (fM). This innovative sensing platform utilizes UCNPs conjugated with one primer and AuNPs with another, targeting the 5' and 3' ends of the SARS-CoV-2 cDNA, respectively, enabling precise differentiation of mismatched DNA sequences and significantly enhancing detection specificity.

Article Synopsis
- The linear economy operates on a "take-make-dispose" principle, causing significant waste and environmental degradation, while a circular economy emphasizes "reduce-reuse-recycle" to minimize this impact.
- The study focuses on integrating coal mine waste and olive pomace to create eco-friendly fired materials, specifically lightweight fired bricks, thus promoting sustainability in construction.
- Results showed that adding olive pomace improved the bricks' properties, such as thermal insulation and strength, underscoring the importance of adopting circular economy practices in the building materials industry.
