The quality of the land, water, and atmosphere are all impacted by environmental contamination. Considerable efforts have lately been made to reduce pollution-causing sources and repair or improve natural soil and water resources. Nano-phytoremediation is more efficient and less hazardous than chemical and physical approaches. They are becoming more and more significant in this field as well as in academia. Different plant species have demonstrated the ability of nanoparticles to remediate soil and water. It is also to be expected that new environmental clean-up methods will be significantly influenced by the most recent biotechnology research. The aim of this paper is to summarise the most significant advancements in phytoremediation immediately. Plants have considerable development potential from the perspective of their phytoremediation qualities. These plants take in contaminants from the soil, water, and other natural resources. New strategies that are targeted by pollutants include segmenting enzyme activity into plant structures. Most contaminants, including heavy metals, are covered by industrial effluents and have been the subject of epidemiological research. It is fascinating to research the risks of these pollutants to develop preventive action against them. This will help us understand the fate of nanomaterials in the environment and environmentally sustainable techniques to remove them from the atmosphere. © 2024 by the authors.

Drought and heavy metals are abiotic stressors that affect soil fertility and plant growth excessively and have significant toxic consequences, threatening agricultural sustainability. Plants ' accumulation of heavy metals in soil uptake leads to disrupting physiochemical and biochemical metabolisms. Biochar has attracted major attention for potential and sustainable soil amendment. Biochar is a complex carbon-rich organic substance whose properties vary depending on the manufacturing process and feedstock. Application of biochar reduces drought stress by increasing the water holding capacity through modification of soil properties, helps in the retention of moisture, absorbs heavy metals, inhibits harmful bacteria, improves soil pH, and also significantly modifies the Reactive Oxygen Species (ROS) scavenging enzymes and provide an efficient electron transferring mechanism to reduce the toxic effects in plants. The review focuses on the effects of drought and heavy metals on soil fertility and plant growth, biochar counteracting the drought and as a soil improver, and the various direct and indirect interaction mechanisms of biochar with the soil. This article also focuses on the potential role of biochar in ameliorating drought and heavy metal stress. © 2024 by the authors.
Exploring the Adverse Impact of Pesticides in Honey Bees and Their Virulence

Honey bees (Apis mellifera L.) significantly enhance seed production, fruit set, and yield through pollination. However, the world is facing a major challenge of honey bee loss due to the excessive use of pesticides facilitated by technological advancements. Pesticides are harmful to pollinators and can cause lethal and sublethal effects through dermal contact, ingestion, or inhalation of contaminated air. Pesticide exposure in agricultural fields has led to honey bee toxicity, which affects their neurophysiological and immune systems and, consequently, their life cycle. This toxicity also leads to contamination of bee products, which can negatively impact human health, affecting the nervous and digestive systems, among others. While there is limited knowledge about the impact of pesticides on wild honey bees, it is crucial to understand this to guide agricultural practices and legislation aimed at safeguarding these important pollinators. It is, therefore, essential to take major steps to control pesticide toxicity in honey bees and prevent further harm. © 2024, AMG Transcend Association. All rights reserved.
Fluorescent Nanoparticles: An Advanced Approach for Latent Fingerprint Development
(Apple Academic Press, 2025) Sneha Lohar; Poonam Kumari; Badal Mavry; Kapil Parihar; Varad Nagar; Pritam P. Pandit; Mahipal Singh Singh Sankhla; Raj Kumar
One of the most reliable characteristics for identifying someone is their fingerprint. In criminal investigations, recovering or gathering latent fingerprints from the crime scene is crucial. The contrast between the 54ridges and the substrate allows for the detection and description of fine features, which is essential for the successful use of created fingerprints for identification. A nanoparticle, often called an ultrafine particle, is a tiny material particle with a size range of 1–100 nm. Due to their small size, nanomaterials are exceptional in their ability to alter mechanical, electrical, and optical properties. At a crime scene, latent or invisible fingerprints are frequently left behind. Some of the nanoparticles used to obtain latent fingerprints include silica, carbon, aluminium, copper, barium, iron, and vanadium. Traditional methods have drawbacks such as low contrast, sensitivity, selectivity, and danger. These methods include powder dusting, chemical processes, and small particle reagent methods. The creation of latent fingerprints using fluorescent nanoparticles is the main subject of this review. Due to their distinctive optical and chemical properties, fluorescent nanoparticles were chosen because they offer greater contrast and sensitivity than conventional methods while also being less dangerous. © 2026 by Apple Academic Press, Inc.
