Omani research study develops eco-friendly method to combat bacteria, fungi
A research study demonstrated that these nanoparticles exhibit significant effectiveness in combating bacteria and fungi, making them promising for various biological applications.
Titled 'Eco-Friendly Synthesis and Characterization of Aluminum Oxide Nanoparticles from Waste Aluminum Foil for Antibacterial, Anti-fungal and Anti-Corrosion Applications," the study addresses the growing issue of aluminum waste, which accumulates in millions of tons annually and is typically disposed of in landfills.
The research aligns with the urgent need to develop advanced recycling technologies to reduce waste and minimize environmental impact. By creating a green synthesis method for aluminum oxide nanoparticles from discarded aluminum foil, the study offers a practical solution to aluminum waste accumulation while exploring the nanoparticles' potential applications in energy storage devices, antimicrobial agents, and corrosion protection.
This approach transforms waste into high-value functional materials, promoting sustainable practices with broad environmental and industrial benefits.
Led by Omani researcher Reem Hilal Al-Maamari from the College of Engineering at the National University of Science and Technology, the research team highlighted the nanoparticles' wide-ranging potential. In healthcare, they could be used to manufacture medical tools and antibacterial coatings, helping reduce infections in hospitals and health centres.
For environmental and waste management, the method enables sustainable aluminum foil recycling, significantly cutting waste volumes and delivering long-term ecological benefits.
In the industrial sector, these nanoparticles could be incorporated into anti-corrosion coatings, particularly for metal and architectural applications.
Their antimicrobial properties also make them ideal for water purification, where they could be used in efficient filtration systems—a viable solution for communities facing water scarcity. In the food industry, the nanoparticles show promise in active packaging technologies, extending shelf life and reducing microbial contamination. Agriculturally, they could serve as natural antifungal agents, enhancing soil and plant health.
The research team emphasized the importance of promoting nanoparticle use, particularly in healthcare, for manufacturing antimicrobial medical tools and surfaces to curb infection transmission in medical facilities. They also recommended their adoption in metal industries, where adding them to protective coatings could mitigate corrosion, especially in humid and marine environments.
For water purification, the nanoparticles' antibacterial properties make them valuable in remote or water-scarce regions. In food packaging, integrating them into materials could enhance product preservation and minimize microbial risks. The team further advocated for their agricultural application as seed or soil treatments to reduce fungal infections and improve crop quality.
The study's findings underscore the transformative potential of repurposing aluminum waste into high-performance nanomaterials, fostering sustainability across multiple sectors while addressing pressing environmental and industrial challenges.

Famine in Gaza threatens thousands with starvation, WHO warns
Gaza: The World Health Organisation (WHO) has warned that Gaza is facing the most severe stage of famine according to the Integrated Food Security Phase Classification, with thousands at risk of dying from hunger. In a statement issued today, the organisation said residents of Gaza are suffering from extreme food shortages, with some going days without eating and others dying from severe weakness or organ failure. Children with acute malnutrition, it added, are particularly at risk of death without urgent treatment. The statement highlighted that Gaza's healthcare system is no longer able to function effectively due to a dire shortage of medical supplies and fuel, compounding the suffering of both patients and healthcare workers. The organisation noted that recovery from malnutrition requires months of specialised medical care and therapeutic feeding, warning that some effects may be lifelong, such as stunted growth and chronic health conditions. The WHO called for the immediate and unhindered entry of humanitarian aid -- food and medicine -- through all possible routes. It urged Israel to facilitate the delivery of assistance and ensure its safe and rapid passage in order to save lives and end the suffering of civilians. The organisation also renewed its call for a ceasefire.

Rare sighting: Over 300 endangered Egyptian vultures spotted in North Al Sharqiyah
Muscat: The Environment Authority in North Al Sharqiyah Governorate today documented a significant sighting of over 300 endangered Egyptian vultures in the Wilayat of Dima Wattayyen. Saif bin Habib Al Naabi, Environmental Systems Supervisor at the Environment Authority in North Al Sharqiyah Governorate, described this as one of the largest recorded sightings of this species in the region. He emphasized the environmental importance of the Sultanate of Oman as a vital habitat for both migratory and resident birds. Al Naabi explained that the Egyptian vulture, scientifically known as Neophron percnopterus, is classified as a globally threatened species, primarily due to habitat loss and poaching. Environmental experts confirm that this unusually large gathering is a strong indicator of the success of environmental conservation efforts within the Sultanate. This phenomenon is considered a positive sign of the rich wildlife diversity in North Al Sharqiyah Governorate, further bolstering efforts to preserve the ecosystems that support such species. This monitoring effort is part of the Environment Authority's ongoing commitment to biodiversity monitoring. The frequent documentation of rare bird species across Oman's governorates solidifies the Sultanate's growing reputation as a destination for ecotourism and scientific research.

Royal Court Affairs succeeds in breeding critically endangered Arabian Leopard
Muscat : The Royal Court Affairs has successfully bred and protected a number of Arabian leopards from extinction by providing healthcare, proper nutrition, and a suitable environment for their reproduction. One of the most notable births at the Wildlife Breeding Center is the female Arabian leopard named "Al-Muzn," now approximately two and a half years old, which is in excellent health after receiving continuous monitoring by specialists at the center. The center, affiliated with the Directorate General of Veterinary Services at the Royal Court Affairs, has also successfully bred and cared for two other leopards—a male and a female—both over three months old. The Arabian leopard requires heightened care during its first few months, as this is a critical phase during which many cubs face mortality risks, including potential maternal rejection. The center has succeeded in early intervention to rescue, nurture, and stabilize the health of these leopards. The center is currently caring for several Arabian leopards originally from Samhan Mountain in Dhofar Governorate, with the goal of increasing their population, protecting them from extinction, and eventually reintroducing them into the wild after ensuring their ability to survive and reproduce. Additionally, the center exchanges expertise, knowledge, and research with other breeding centers in the region. It is worth noting that the center also breeds and conserves various other species native to Oman's environment, such as the Arabian gazelle, the Arabian tahr and other wildlife.
