Researchers at the Federal University of São Carlos (UFSCar) in São Paulo, Brazil, have made significant strides in food safety with the development of a novel sensor designed to detect sodium nitrite (NaNO2) in various beverages like mineral water, orange juice, and wine. Sodium nitrite, often used as a preservative and color-fixative in processed meats such as ham and bacon, poses health risks due to its potential to form nitrosamines, carcinogenic compounds that can lead to serious health [...]

Scientists observed ring formation around a small icy celestial body orbiting between Saturn and Uranus, called Chiron. The rings are made mainly of water ice mixed with small amounts of rocky material, like those of Saturn, said Chrystian Luciano Pereira, lead author of the study. Chiron exhibits comet-like activity by ejecting gas and dust into space.

Astronomers have made a groundbreaking discovery in our solar system—a ring system forming around Chiron, a small icy object located between Saturn and Uranus. This revelation not only enhances our understanding of Chiron but also has significant implications for studying ring systems throughout the universe. Unlike the grand rings of Saturn, Chiron's emerging ring system presents a unique opportunity to explore the formation and evolution of rings around smaller celestial [...]

Regular physical activity has long been celebrated for its role in enhancing physical fitness, but recent research underscores its significant impact on immune function, particularly in older adults engaged in endurance training. A study conducted by an international team has revealed that these older athletes possess immune cells with superior adaptability and efficiency compared to their sedentary counterparts. The focus of the study, published in Scientific Reports and supported by [...]

In addition to strengthening the heart, lungs, and muscles, regular physical exercise enhances the immune system, new research reveals. An international team studying older adults with a long history of endurance training found that sustained physical activity improves the adaptability and efficiency of immune cells. Endurance Exercise Strengthens Natural Killer Cells Researchers from São Paulo State University (UNESP), Justus Liebig University Giessen (JLU) in Germany, and other [...]

Green tea has long been known to promote weight loss. It’s been a favourite of ancient cultures for centuries, but now the tea has something fresh steeping in its cup, scientific validation. New research from Brazil’s Cruzeiro do Sul University has revealed that green tea extract helps lose weight and improve metabolism. The findings offer a glimpse into how this the leaf could support healthier living. Professor Rosemari Otton spent over 15 years investigating its effects. Her most [...]

Green tea, revered for centuries for its medicinal qualities and rich antioxidant content, has garnered renewed attention in the realm of metabolic disease research. Studies funded by FAPESP have uncovered significant insights into how green tea can combat obesity and improve glucose sensitivity and insulin resistance, particularly in obese mice. These findings bolster the case for green tea as an adjunct treatment for obesity in humans. Leading the research efforts is Rosemari Otton from [...]

Green tea, a beverage long celebrated for its antioxidant and medicinal properties, may offer more than just a refreshing drink. New research from Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) suggests that green tea extract can help the body burn fat, improve metabolism, and support overall metabolic health. In controlled studies with obese mice, the extract helped reduce body weight, enhance glucose sensitivity, and preserve muscle structure, all [...]

In addition to strengthening the muscles, lungs, and heart, regular physical exercise also strengthens the immune system. This finding comes from a study of older adults with a history of endurance training, which involves prolonged physical activity such as long-distance running, cycling, swimming, rowing, and walking. An international team of researchers analyzed the defense cells of these individuals and found that “natural killer” cells, which patrol the body against viruses [...]
