Social Inequality Worsens Exercise Barriers, Study Finds
Publicado em 31 de julho de 2026
A ten-year study of residents of the city of São Paulo, Brazil, revealed that leisure-time physical activity is highly unequal and that the gap between social strata is widening. While highly educated white men are exercising more, women from racial minorities with low levels of education have the lowest rates of physical activity during leisure time. In contrast, exercise associated with urban transportation, such as walking to work, is distributed more evenly across different population [...]

Dads Ultra-Processed Food Intake Tied to Babys Size
Publicado em 29 julho 2026A father's diet can affect his children's health and body composition before they are even conceived. A study of 43 triads of fathers, mothers, and newborns treated in the public healthcare system of Ribeirão Preto in the state of São Paulo, Brazil, demonstrated this. The analysis revealed that the greater the consumption of ultra-processed foods by the fathers, the higher the birth weight and the greater the accumulation of fat in the baby's thighs and suprailiac region (commonly [...]Mirage News (Austrália) -

Harmful Substance Found in Solid Waste
Publicado em 28 julho 2026In a study conducted by São Paulo State University (UNESP) in Brazil and the University of Birmingham in the United Kingdom, the presence of chlorinated organophosphorus esters was identified in samples of solid waste – discarded materials that could be used by others. These substances are used in industry as flame retardants and plasticizers. Due to their thermal stability and low cost, they are widely used in products such as polyurethane foam for furniture and mattresses, plastic [...]Mirage News (Austrália) -
Frog peptide could increase the shelf life of strawberries
Publicado em 24 julho 2026Five minutes. That was the amount of time that strawberries remained in contact with the Ctx(Ile21)-Ha peptide — a molecule isolated from a frog native to the Brazilian Cerrado — in experiments conducted in Brazil by scientists at the Tupã campus of São Paulo State University (UNESP). It was enough to demonstrate the molecule’s potential to extend the shelf life of the fruit, which is highly perishable. “The peptide alone, without any other components, maintained the [...]Food Processing (Austrália) -
Soybean-Cotton Pest's Fungi Can Degrade Polystyrene
Publicado em 24 julho 2026A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton, and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as Styrofoam. In an article published in the journal BMC Microbiology, researchers from the Federal University of São Carlos (UFSCar) and São Paulo State University (UNESP) in Brazil presented the results of a study investigating the gut microbiota of Helicoverpa armigera [...]Mirage News (Austrália) -
Depoliticization Undermines AIDS Fight in Brazil
Publicado em 17 julho 2026Brazil's HIV/AIDS response program is considered a success story. As early as 1987, Brazil became the first developing country to guarantee free treatment. The country is also known for its social activism, which helped build the Unified Health System (SUS) and shape public policies based on scientific evidence and human rights. Important milestones in the fight against AIDS emerged through the alliance between civil society, public health professionals, and the government, such as [...]Mirage News (Austrália) -
Common Food Additive May Harm Gut Health, Study Shows
Publicado em 16 julho 2026Many foods on supermarket shelves contain ingredients that most people never notice. One of them is xanthan gum, a common food additive used to make foods thicker, creamier, and more stable. It helps keep ice cream smooth, prevents sauces from separating, improves gluten-free baking, and thickens drinks for people who have trouble swallowing. Although it has been widely used for decades, new research suggests scientists should investigate whether frequent, long-term use could have [...]KSR - knowRidge Science Report (Austrália) -
Forests, Rivers Boost Amphibians' Microbiome Defense
Publicado em 16 julho 2026A study published in the Proceedings of the National Academy of Sciences indicates that a frog's resistance to a fungus that has decimated hundreds of amphibian species worldwide is due not only to its genes, but also to the beneficial bacteria living on its skin and to the organization of its surrounding landscape. Scientists have demonstrated that a disconnect between forests and bodies of water impairs amphibians' ability to recruit defensive microbes, making them more [...]Mirage News (Austrália)
