Brazilian researchers analyzed behavioral and physiological factors in animals whose mothers received a synthetic substance that activates the same receptors as marijuana during pregnancy. The consequences were different in males and females.
Promising results were obtained by a group at the Brazilian Center for Research on Energy and Materials (CNPEM), working with collaborators elsewhere. They combined inhibition of glutaminase, an enzyme that converts glutamine into nutrients for tumor cells, with inhibition of HuR, a protein that regulates the RNA of glutaminase.
Characterized by high pH and salinity, these water bodies have practically dried up because of rising temperatures, changing rainfall patterns, and wildfires. The findings show how the local microbial community and other factors influence greenhouse gas emissions.
In an article published in Perspectives in Ecology and Conservation, researchers affiliated with the National Space Research Institute (INPE) and the National Disaster Surveillance and Early Warning Center (CEMADEN) in Brazil discuss CO2 emission reduction challenges and solutions.
A study by the University of São Paulo shows that expansion of cattle ranching to meet growing domestic demand has contributed more than any other driver to the elimination or degradation of the Amazon’s original vegetation, followed by expanding croplands and urbanization.
Researchers at UNICAMP and other Brazilian universities, as well as 20 companies, are participating in the DUNE experiment. They are responsible for the argon purification and photon detection processes, without which the international mega-project would be impossible.
Through morphological and molecular analysis of material collected from rivers in Brazil's Northeast region, the researchers are extending their knowledge of the evolutionary history of South American darters in the genus Characidium.
A study conducted by Brazilian scientists and colleagues in other countries shows that earthquakes, hurricanes, tsunamis and volcanic eruptions increase the risk of extinction for mammals, birds, reptiles and amphibians. The natural events may have synergies with hazards due to human activity.
Researchers affiliated with the FAPESP Research Program on Global Climate Change met at the State University of Campinas in Brazil to discuss current research priorities in the effort to understand and combat the consequences of the extreme events caused by global warming.
Researchers at São Paulo State University (UNESP) in Brazil evaluated the effect of three different low-cost training programs on a group of socially vulnerable female volunteers. HIIT combined with muscle strength exercises was the most efficacious in terms of reducing blood pressure and arterial stiffness, the main risk factors for cardiovascular disease.

In PLOS Pathogens, researchers at the University of São Paulo in Brazil report a study based on autopsies of 47 patients who died after being infected by the ancestral strain of SARS-CoV-2. The findings will support clinical decisions on the treatment of critical cases.
A report by an international group of researchers including three Brazilians shows that climate change tripled the probability of weather conditions favoring unprecedented wildfires in Canada and multiplied it by a factor of 20 in western Amazonia between March 2023 and February 2024. Global carbon emissions were 16% above average.
