According to researchers in Brazil, people who suffer from post-traumatic stress disorder often report constant clenching or grinding of the teeth during the day, a condition known as awake (or diurnal) bruxism. In this study by a team at the University of São Paulo’s Medical School—and published in Clinical Oral Investigations —patients diagnosed with PSTD were submitted to a clinical examination to assess their oral health. According to the researchers, besides [...]

Although the rate of deforestation in the Brazilian Amazon fell in 2023, the region is faced by another challenge in the shape of fire affecting the native vegetation that has so far been spared destruction. An article published in the journal Global Change Biology warns that wildfires in old-growth forests rose 152% last year compared with 2022, despite a drop of 16% in the total number of fires throughout the Amazon and a 22% drop in deforestation. In an aalysis of satellite images, the [...]

Fabrication of sensors by 3D printing combines speed, freedom of design, and the possibility of using waste as a substrate. Various results have been obtained in a circular economy mode, whereby residues usually thrown away are instead used as low-cost resources. A highly creative solution involving the printing of electrochemical sensors on fallen tree leaves has now been presented by a team of researchers in Brazil led by Bruno Janegitz, a professor at the Federal University of São [...]

An article published in The Faseb Journal describes a Brazilian study analyzing the correlation between two key energy metabolism regulation processes: the absorption and release of calcium ions by mitochondria, the organelles that generate energy for cells; and autophagy induced by calorie restriction. Autophagy occurs when cells break down and reuse their own cytoplasm. The study was conducted at the Center for Research on Redox Processes in Biomedicine (Redoxome), a Research, Innovation [...]

The relationship between living in a polluted city like São Paulo (Brazil) and lung disease or cancer is well known. But the problems go further. Unprecedented research shows that long-term exposure to air pollution is directly linked to increased heart risks in residents of the capital of the state of the same name. People with high blood pressure are at even greater risk. The study, published in the journal Environmental Research, was conducted by researchers from the University of [...]

As the impacts of climate change increasingly affect the daily lives of residents in several countries, including Brazil, the resilience of forests, especially tropical ones such as the Amazon, has become a frequent topic of research. In addition to studying various factors that influence the way vegetation reacts to global warming, scientists are seeking to improve vegetation models – tools that play a crucial role in understanding and managing ecosystems, contributing to biodiversity [...]

The social and environmental impact of the Belo Monte dam and hydroelectric power plant in Pará state, Brazil, has been called a “disaster” by researchers, environmentalists and several media outlets. The damage has again been highlighted recently in an inspection report issued by the Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA), an agency of the Ministry for the Environment and Climate Change. The inspectors detected silting and erosion [...]
