Reducing Methane Emissions via Nelore Cattle Microbiota Mapping
Publicado em 04 de novembro de 2026
Nelore Cattle Microbiota Mapping Targets Methane Reductions
Researchers at the Brazilian Agricultural Research Corporation, known as EMBRAPA, are mapping the link between Nelore cattle genetics and gut microorganisms to cut methane emissions and boost feed efficiency, phys.org reported. Luciana Regitano presented the findings on October 28 during FAPESP Week Netherlands.
Cattle produce methane through natural digestion in the rumen, the largest stomach chamber, where microorganisms break [...]

Ancient Brazilian Termite Mounds: Size of Great Britain
Publicado em 07 setembro 2026Two hundred million evenly spaced dirt cones covering an area the size of Great Britain in northeastern Brazil's caatinga region were built by a single leaf-eating termite species, Syntermes dirus , over four millennia, according to research published by entomologist Stephen Martin of the University of Salford and botanist Roy Funch of the Universidade Estadual de Feira de Santana in a 2018 study in Current Biology . Scale and Dimensions of the Brazilian Murundus The mounds, locally [...]ver notícia -
Common Supplements Rival Antibiotics for Severe Gum Disease
Publicado em 30 agosto 2026According to researchers, the findings offer a potential alternative for managing the chronic inflammatory disease while helping reduce unnecessary antibiotic use amid growing global concerns over bacterial resistance. Clinical Study Design and Patient Cohort The research evaluated 109 people with advanced periodontitis who were followed for one year. In advanced cases, the disease can destroy supporting bone, loosen teeth, and eventually cause tooth loss. Comparing Four Treatment [...]ver notícia -
Omega-3 and ASA Combination Promising for Severe Periodontitis
Publicado em 07 agosto 2026A combination of omega-3 and low-dose acetylsalicylic acid (ASA) achieved clinical results comparable to antibiotics in treating severe periodontitis, according to a study published in the May issue of the Journal of Periodontology . Researchers affiliated with Albert Einstein Israelite Hospital, Guarulhos University, the University of Taubaté, and the Ribeirão Preto School of Dentistry at USP in Brazil, alongside Harvard University in the United States, tracked 109 patients with advanced [...]ver notícia -
Secondhand Smoke and Tooth Mineralization: New Research Findings
Publicado em 31 julho 2026Exposure to secondhand cigarette smoke during the first days of life can alter tooth enamel mineralization without causing visible damage to the teeth, according to an animal model study published in May in the scientific journal Calcified Tissue International . Researchers at the Ribeirão Preto School of Dentistry at the University of São Paulo (FORP-USP) in Brazil found that early smoke exposure reduces phosphorus levels and increases organic carbon in developing dental enamel, raising [...]ver notícia -
Widening Inequality in Leisure-Time Physical Activity: New Study Findings
Publicado em 30 julho 2026A ten-year longitudinal study published in May in the International Journal of Behavioral Nutrition and Physical Activity reveals that leisure-time physical activity in São Paulo, Brazil, is deeply unequal, with the gap between social strata widening significantly over time. According to scientists at the University of São Paulo (USP), highly educated white men are exercising more, while women from racial minorities with low levels of education face the lowest participation rates. The [...]ver notícia -
How Diabetes Increases Long COVID Risks: Key Complications Explored
Publicado em 04 julho 2026Diabetes mellitus increases the risk of severe cardiovascular complications and impaired physical recovery following COVID-19, according to a study supported by the São Paulo Research Foundation (FAPESP). Researchers found that systemic inflammation in diabetic patients compounds viral toxicity, making the heart a primary target for damage and increasing the likelihood of post-hospitalization falls. Why does diabetes increase COVID-19 heart risks? The cardiovascular system in people with [...]ver notícia -
New CT Marker Refines Gastric Cancer Prognosis
Publicado em 20 junho 2026Researchers have developed a new biomarker called VMD that uses artificial intelligence to predict gastric cancer survival by analyzing fat and muscle density in CT scans. According to the São Paulo Research Foundation, patients with higher VMD values face a significantly worse prognosis, with a median survival of 13.8 months compared to 58.5 months for those with lower values. How are AI-driven biomarkers changing cancer staging? Current gastric cancer treatment typically relies on [...]ver notícia -
GMT Brazil Launches New Astronomy Short Video Series
Publicado em 18 junho 2026The Brazilian office of the Giant Magellan Telescope (GMT Brasil) has launched “Jornada das Imagens Espaciais,” a series of short-form vertical videos designed to document the visual history of the solar system. According to the project, the initiative aims to engage younger audiences by using high-definition imagery to bridge the gap between historical astronomical observations and modern, high-resolution scientific data. How Short-Form Content is Changing Science [...]ver notícia -
New CT Scan Biomarker Predicts Gastric Cancer Outcomes
Publicado em 17 junho 2026Researchers at the State University of Campinas (UNICAMP) in Brazil have identified a new biomarker, the Visceral-Muscular Density (VMD) index, that significantly improves prognosis prediction for gastric cancer patients. By analyzing radiodensity patterns in CT scans—a standard diagnostic tool—the team discovered that VMD can distinguish between high-risk and low-risk disease progression, potentially allowing for more personalized treatment plans that account for a patient's unique [...]ver notícia
