Healing Power of Nature

The Healing Benefits of Nature for Cancer Patients’ Well-Being

Nature plays a meaningful role in the lives of people living with cancer by providing restorative physical and psychological spaces enriched with personal significance. The natural environments help patients reconnect with life, find respite from clinical settings, reflect on their experiences, gain comfort, reinterpret their illness, remain physically active, and appreciate everyday moments. These benefits contribute to improved emotional well-being, resilience, and overall quality of life. These findings support integrating nature-based interventions and healing environments into cancer care as valuable, evidence-informed complements to conventional medical treatment and supportive care.

Seven microbial solutions revolutionizing environmental biotechnology

Seven microbial solutions for sustainable environment

Microbial bioprocesses offer promising solutions to global environmental challenges through innovative strategies such as enhanced carbon dioxide (CO₂) capture, improved soil water retention, plastic biodegradation, removal of pharmaceuticals and endocrine-disrupting chemicals, biological nitrogen fixation, phosphorus recovery and recycling, and efficient conversion of lignocellulosic biomass. These advances demonstrate the practical potential of engineered microorganisms for sustainable development. Technological advancements in microbial biotechnology can support climate action, resource conservation, pollution control, sustainable agriculture, and the transition to a resilient, circular bioeconomy with tangible environmental and societal benefits.

The Hidden Role of Bed Dust Bacteria in Children’s Respiratory Health

The bacterial microbiome in household bed dust is strongly influenced by environmental factors and may play an important role in childhood asthma. When 90 bed dust samples were analysed using high-throughput 16S rRNA gene sequencing, significant differences in bacterial community composition between asthmatic and healthy children have been found. Factors such as living environment, housing type, pet ownership, and cleaning practices were found to shape indoor microbial diversity. Fostering a healthy diverse indoor microbiome could support respiratory health and inform future indoor air quality and healthy home strategies.

Artificial Light at Night Increases Type 2 Diabetes Risk

Artificial Light at Night Increases Type 2 Diabetes Risk

Artificial light at night (ALAN) is an increasingly prevalent environmental exposure that may contribute to the rising burden of type 2 diabetes. Nighttime light disrupts circadian rhythms, suppresses melatonin production, impairs insulin sensitivity, and promotes unhealthy lifestyle behaviours associated with poor metabolic health. The ALAN timing, duration, and wavelength of light exposure significantly influence diabetes risk. Strategies such as optimizing sleep environments, minimizing evening screen exposure, and adopting chrononutrition and chronotherapy may help reduce diabetes risk and support better metabolic health, healthier lifestyle habits, and wound enhance diabetes management.

The benefits of Green Spaces on children’s Quality of Life

Access to natural environments including parks, water bodies, and vegetation within 500 meters of children’s homes plays an important role in supporting children’s Health-Related Quality of Life (HRQOL). Research shows that these natural features are associated with improved physical, social, and overall well-being, particularly among urban and suburban children. The relationship between nature and well-being varies across urban, suburban, and rural communities. These findings underscore the importance of designing nature-friendly environments and policies that promote healthier lifestyles, child development, and long-term well-being.

Natural Bioherbicides

Natural bioherbicides for effective weed control and cleaner agriculture

Natural bioherbicides are emerging as promising eco-friendly alternatives to chemical herbicides for controlling Cyperus rotundus (purple nutsedge), one of the most persistent agricultural weeds. Aqueous leaf extracts of Nerium (Nerium oleander), Castor (Ricinus communis), and Olive (Olea europaea) at concentrations of 5%, 7.5%, and 10% have demonstrated significant weed-suppression potential. Among them, Nerium extract exhibited the strongest allelopathic effect, achieving up to 90% germination inhibition and complete suppression at a 10% concentration. These plant-derived bioherbicides can potentially reduce dependence on synthetic chemicals, minimize environmental pollution, and promote sustainable agricultural practices.

Moringa oleifera offers a cost-effective solution for microplastic removal from drinking water

Moringa oleifera offers a cost-effective solution for microplastic removal from drinking water

Recently, Moringa oleifera have been studied to reduce aged polyvinyl chloride microplastics (Aged-PVC MPs) from drinking water. Acting as a natural coagulant, Moringa oleifera seed saline extract (MOS-SE), achieved an impressive 98.5% microplastic removal efficiency, matching the performance of conventional alum-based treatment. When tested, in-line filtration was found to be as effective as direct filtration, eliminating the need for an additional flocculation step and reducing treatment complexity and costs. Additionally, MOS-SE effectively reduced aromatic organic matter, demonstrating its potential as a sustainable, eco-friendly, and cost-effective solution for modern drinking water treatment.

Placental Health Risks Linked to Aromatic Hydrocarbon

Placental Health Risks Linked to Aromatic Hydrocarbon Exposure in Pregnancy

Higher exposure to environmental polycyclic aromatic hydrocarbons (PAHs) among women living in polluted areas has been linked to harmful effects on the human placenta. Key PAH biomarkers, including phenol and 1-hydroxypyrene, were associated with reduced placental hormone activity and decreased metabolic enzyme expression, indicating impaired placental function. It was also observed that lower expression of placental glutathione transferase and reduced placental phosphatase activity in placentas from polluted regions. In contrast, placentas from non-polluted areas showed significantly higher estrogen receptor activity and placental gonadotropin expression, highlighting the serious impact of industrial pollution on maternal and fetal health.

Linkage between heavy metal resistant genes and antibiotic resistant genes

Marine E. coli Shows Strong Link Between Heavy Metal and Antibiotic Resistance

About 18 heavy metal resistance genes (HMRGs) associated with arsenic, cadmium, copper, and mercury resistance were identified in 308 E. coli isolates through whole genome sequencing and advanced bioinformatics analysis. Researchers also examined 25 antibiotic-resistant bacterial genomes and discovered important links between HMRGs and antibiotic resistance genes (ARGs). Notably, 100% of the analyzed genomes carried at least one copy of 11 out of the 18 identified HMRGs. These findings suggest that environmental pollution may play a significant role in driving antimicrobial resistance. The study also highlights the potential of using bacterial resistance genes as biomarkers for environmental contamination and emerging public health risks.

Microbial Electrochemical Technology Treats Nitrate and Arsenic-Contaminated Groundwater

Microbial Electrochemical Technology Treats Nitrate and Arsenic-Contaminated Groundwater

Microbial electrochemical technologies (METs) uses electro-bioremediation systems that can treat groundwater contaminated with nitrate and arsenite simultaneously. A continuous-flow bioelectrochemical reactor has been developed that reduces nitrate into harmless dinitrogen gas while oxidizing toxic arsenite into less harmful arsenate. The system can achieve high nitrate removal rates and over 95% arsenite oxidation efficiency under groundwater-like conditions. This works as the internal recirculation significantly improves treatment performance by enhancing mass transfers and microbial activity of denitrifying and arsenite-oxidizing bacteria like Sideroxydans sp and Achromobacter sp. Thus, electro-bioremediation as a sustainable, low-chemical, and energy-efficient solution for complex groundwater contamination challenges.
