Brazilian researchers investigated the complexity of the world's largest wetland biome, predicting heavier rainfall and longer dry periods, and proposing six guidelines for sustainable governance of the region (landscape in lower Nhecolândia, a lobe of the Taquari River mega-fan in the Pantanal). Credit: Mario Luis Assine/UNESP The Pantanal represents 1.8% of Brazil's total area, occupying 150,000 square kilometers in Mato Grosso and Mato Grosso do Sul states. With a mixture of [...]

Researchers at the University of São Paulo's Center for Nuclear Energy in Agriculture (CENA-USP) in Brazil, collaborating with colleagues in Canada, France, Italy and Spain, reviewed 1,154 original scientific articles published between 2009 and 2022 on the effects of nanomaterials in 1,374 plants belonging to 253 species. The metadata review assembled and organized quantitative information on the experimental parameters used in the scientific literature of the past decade. With [...]

The study involved twenty-one different patients with metabolic syndrome. They were given either a calorie-restricted or protein-restricted diet. According to new research, protein restriction is effective in combating obesity and diabetes. According to a study comparing the effects of protein and calorie restriction diets in humans, reducing protein consumption may help control metabolic syndrome and some of its primary symptoms, such as obesity, diabetes, and high blood pressure [...]

For the first time, scientists at the Federal University of São Paulo (UNIFESP) in Brazil have shown that infection by SARS-CoV-2, the virus that causes COVID-19, changes the functioning of host cell RNA. They arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA. The most recent study, reported in an article published in Frontiers in Cellular and Infection Microbiology, examined the epitranscriptome of Vero cells (derived [...]

 by André Julião, FAPESP Tiger Beach in the Bahamas is famous for its paradisiacal beauty and for being frequented by an animal that might scare most people away but is actually an outstanding diving tourism attraction: the Tiger shark (Galeocerdo cuvier). The sea is crystal clear and only 5 m deep on average, so the sharks, which can surpass 3 m in length, can easily be seen. They are drawn to the site by local tour operators, who throw fish and other food into the [...]

Brazilian study analyzed active fire occurrences between 2003 and 2020 in the nine countries with Amazon Rainforest areas. Brazil accounted on average for 73% of the fires detected in the period. Credit: Liana Anderson/CEMADEN A Brazilian study shows that the number of fires detected in the entire Amazon region between 2003 and 2020 was influenced more by uncontrolled human use of fire than by drought. According to the researchers, burning of vegetation to prepare areas for pasture and [...]

Brazilian researchers interviewed 1,905 children twice in seven years and analyzed 22 risk factors that can influence human development. An article on the study is published in Scientific Reports. Credit: Agência CNJ de Notícias A significant reduction in childhood poverty could cut criminal convictions by almost a quarter, according to a study conducted in Brazil. An article on the study is published in Scientific Reports. The researchers used an innovative approach involving [...]

Summary: Researchers identify a neuromuscular circuit that links the burning of muscle fat during physical exercise to the action of a protein in the brain. Source: FAPESP An article published in Science Advances describes a neuromuscular circuit that links the burning of muscle fat to the action of a protein in the brain. The findings, obtained in Brazil by researchers at the State University of Campinas (UNICAMP) and the University of São Paulo (USP), contribute to a deeper [...]

Scenarios of PAs downgrading in the study region with respective road network required to access mineral deposits. Credit: Nature Sustainability (2022). DOI: 10.1038/s41893-022-00921-9 A model developed by Brazilian researchers shows that opening up protected areas of the Amazon to mining projects would lead to the deforestation of 183 square kilometers (km²) due directly to new mines and the loss of an additional 7,626 km² of forest to the direct and indirect impacts of [...]
