A new NMR method has enabled the direct observation of heterochalcogen bonds in redox systems, revealing strong redox activity. This innovative approach allows for the generation and characterization of trichalcogenide molecules containing sulfur, selenium, or tellurium.
A study published in Environmental and Biogeochemical Processes reveals that soil warming during heatwaves does not lead to an increase in arsenic levels in rice grains. Rice physiology and seasonal factors play a bigger role than previously thought in determining the risks of food safety under climate extremes.
Researchers developed a biodegradable liquid slow-release mulch film based on bamboo residue for selenium-enriched crop cultivation. The film showed enhanced moisture retention, insulation properties, and weed suppression, improving soil temperature and humidity.
A recent study published in PLOS ONE found that higher maternal selenium levels during pregnancy are associated with a lower risk of streptococcal infections in children. The research tracked over 74,000 mothers and their children to explore potential links between maternal metal exposure and infection risk.
Researchers at Washington University in St. Louis have made strides in removing selenium contamination from water using iron electrocoagulation, a process that generates iron-containing solids with large surface areas to bind selenium. The method removed more than 98% of selenium by flowing through an iron reactor for 11 seconds and se...
Pacific children are not meeting daily recommended intakes for key micronutrients, leading to associations with childhood obesity and acanthosis nigricans. The study highlights excessive sodium intake across the region, posing cardiovascular health risks.
Researchers are discovering selenium nanoparticles' potential in cancer prevention, inflammation reduction, and tumor treatment through their ability to activate the immune system and reduce inflammation. SeNPs are also being explored as vaccine adjuvants to improve immune cell activation and boost cancer vaccine efficacy.
Researchers have discovered a new pathway for selenoprotein production, led by PRDX6, which can sustain selenium protein synthesis. Inhibiting PRDX6 may impair cancer cell survival, particularly in neuroblastomas, offering a new therapeutic target.
A new study found significant intake inadequacies for nearly all evaluated micronutrients, with iodine and vitamin E deficiencies being the most prevalent. The researchers estimated inadequate intakes were higher for women than men in some countries, highlighting a need for targeted dietary interventions.
Researchers at Lawrence Berkeley National Laboratory identified 28 trace metals in secondhand and thirdhand tobacco smoke, including cadmium, arsenic, and chromium. The study found that the predicted indoor air concentration for these metals exceeded California's cancer risk guidelines, highlighting the need to understand their contrib...
Researchers have developed a new technique to understand the relationship between atomic structure and electric polarization in 2D van der Waals ferroelectric materials. This discovery is expected to revolutionize domain engineering in these materials, positioning them as fundamental building blocks for advanced devices.
A study in mice shows that exposure to pollutant mixtures increases health damage and suggests selenium can mitigate this effect by activating antioxidant defenses. Selenium was found to reduce molecular damage caused by the pollutants.
Researchers found that higher selenium levels were associated with lower blood pressure and HDL concentration in middle-aged women. The study suggests that selenium may moderate the effect of genetic variants on MetS components, such as waist circumference.
Researchers from Swansea University and Université Grenoble Alpes demonstrate the effectiveness of selenium nanoparticles in killing ovarian cancer cell models. The study reveals a novel biological mechanism underlying the anti-cancer effect, involving histone methylatransferases and epigenetic processes.
A Mediterranean diet rich in colourful fruits and vegetables helps prevent prostate cancer and speeds up recovery after radiation treatment. Foods such as tomatoes, melons, and nuts are particularly beneficial due to their high levels of lycopene and selenium.
A new UNCG study confirms that SARS-CoV-2 destroys the antioxidant activity of key human selenoproteins, weakening immunity and enabling virus replication. The findings suggest investigating selenium supplementation and dietary sulfur compounds as potential symptomatic treatments for COVID patients.
Researchers have developed a new type of low-cost selenium solar cell using tellurium alloy, which improves efficiency by expanding the absorption spectrum. The Se-1-x Te-x alloy system has shown promise in achieving high performance, with efficiencies over 1.85% achieved after nine months in air.
A laboratory study by Berkeley Lab's researchers reveals that green rust can chemically react with toxic selenium, converting it to a safer elemental form. This finding offers a possible new approach to addressing selenium contamination in soils and sediments.
The study reveals a family of selenium-based compounds that can lower blood pressure without toxic side effects. These compounds could lead to the development of new therapeutic agents, expanding knowledge on selenium's role in human health.
A 10-year study found that men and women taking selenium supplements had 41% less total cancer compared to those taking a placebo. The study also showed significant reductions in specific types of cancer, including prostate, esophageal, colorectal, and lung cancers.
Hydrated lime has been shown effective in reducing sulfur dioxide emissions, now researchers found it also reduces selenium. At 400-600 degrees Celsius, the compound captures up to five percent of its weight in selenium.
