Benefits and risks of hair, skin, and nail supplements in older adults

mycolabadmin

This article reviews popular supplements that older adults, especially women, take to improve their hair, skin, and nails. While some supplements like nicotinamide show promise for sun-damaged skin, most lack strong evidence of benefit in healthy people. Important risks include biotin interfering with heart and thyroid tests, too much zinc causing copper deficiency, and excess vitamins A and E building up to toxic levels. Doctors should talk to older patients about these supplements and help them make informed decisions based on scientific evidence rather than marketing claims.

Ayahuasca enhances the formation of hippocampal-dependent episodic memory without impacting false memory susceptibility in experienced ayahuasca users: An observational study

mycolabadmin

Researchers studied how ayahuasca affects memory in experienced Santo Daime church members who use it regularly. Surprisingly, instead of impairing memory like other psychedelics typically do, ayahuasca enhanced people’s ability to remember details of events they witnessed. Importantly, the drug did not make people more susceptible to false memories or memory distortions, even though the entire study occurred while participants were under its acute effects.

Microplastic pollution in Himalayan lakes: assessment, risks, and sustainable remediation strategies

mycolabadmin

Plastic particles called microplastics are increasingly polluting Himalayan lakes through tourism, waste, and glacier melting, harming fish and water quality. Scientists are testing various cleanup methods including physical filters, chemical treatments, and microbe-based solutions. Tiny engineered materials under UV light show promise for breaking down plastics in cold mountain environments. Better policies, monitoring, and community action are needed to protect these important freshwater sources.

Physiological Insights into Enhanced Epsilon-Poly-l-Lysine Production Induced by Extract Supplement from Heterogeneous Streptomyces Strain

mycolabadmin

Researchers discovered that exposing bacteria that produce epsilon-poly-l-lysine (a natural antimicrobial compound) to extracts from another closely related bacterium dramatically increases production by 2.6-fold. Using advanced analysis techniques, they found that this boost occurs because the extract triggers the bacteria to activate defense mechanisms, rerouting its metabolism to produce more of this antimicrobial compound. This finding could significantly reduce the cost of producing this useful natural preservative for foods and medicines, making it more commercially viable.

Extraction, Characterization, Biological Properties, and X-Ray Fluorescence Analysis of Functional Polysaccharides Derived from Limnospira platensis

mycolabadmin

Spirulina (Limnospira platensis) is a nutrient-dense microalga that contains beneficial polysaccharides with multiple health benefits. Researchers extracted and analyzed these polysaccharides, finding they have strong antioxidant properties and can help regulate blood sugar levels by inhibiting α-glucosidase enzymes. These compounds also support beneficial gut bacteria growth, making spirulina a promising natural ingredient for functional foods and health supplements.

Current state of the heavy metal pollution, microbial diversity, and bioremediation experiments around the Qixia Mountain lead–zinc mine in Nanjing, China

mycolabadmin

A lead-zinc mine in Nanjing, China has contaminated surrounding soils with dangerous heavy metals like lead, zinc, and cadmium over 70 years of operation. Researchers discovered that combining amaranth plants with a beneficial bacterium called Bacillus velezensis dramatically reduced heavy metal pollution in soil, lowering pollution levels from severely contaminated to acceptable levels. This plant-microorganism approach also improved plant growth while reducing heavy metal uptake in the edible parts of crops, offering a practical solution to make farmland around mines safer for growing food.

Genomic Insights into the Microbial Agent Streptomyces albidoflavus MGMM6 for Various Biotechnology Applications

mycolabadmin

Scientists analyzed the genetic makeup of a soil bacterium called Streptomyces albidoflavus MGMM6 and discovered it has remarkable abilities for cleaning up pollution. The bacterium can break down harmful dyes used in industries, remove heavy metals from wastewater, and kill plant disease-causing fungi. These findings suggest this microorganism could be used in agriculture to protect crops and in environmental cleanup efforts.

Novel Antimicrobial Activities of Albofungin, Albonoursin, and Ribonucleosides Produced by Streptomyces sp. Caat 5-35 Against Phytopathogens and Their Potential as a Biocontrol Agent

mycolabadmin

Scientists discovered that a soil bacterium called Streptomyces sp. Caat 5-35 produces natural compounds that can kill crop-damaging pathogens. These compounds, including albofungin and albonoursin, showed strong activity against diseases affecting cacao and palm crops. The bacterium also helps plants by breaking down cellulose and making phosphorus more available, making it a promising tool for natural crop protection without synthetic chemicals.

Rice varietal intercropping mediates resistance to rice blast (Magnaporthe oryzae) through core root exudates

mycolabadmin

Growing different varieties of rice together can help protect susceptible rice plants from blast disease. When resistant and susceptible rice varieties are planted together, the resistant plants release special chemicals from their roots that help the susceptible plants fight off the fungal disease. Scientists identified four key chemicals—azelaic acid, sebacic acid, betaine, and phenyl acetate—that work together to boost the immune system of susceptible rice plants and directly kill the blast fungus.

Koumiss (Fermented Mare’s Milk) as a Functional Food: Bioactive Proteins, Peptides, and Future Perspectives

mycolabadmin

Koumiss is a fermented mare’s milk beverage consumed for centuries in Central Asia that offers unique health benefits. Unlike cow’s milk, mare’s milk is easier to digest, contains natural antimicrobial proteins, and when fermented develops thousands of bioactive peptides and beneficial bacteria. These compounds may help with cardiovascular health, gut function, and immune support, making koumiss a promising functional food for modern nutrition.
