Artificial intelligence assessment indicates stress levels in farmed Amazonian fish
Publicado em 08 setembro 2025(Press-News.org) In Brazil, a group led by researchers from São Paulo State University (UNESP) in Jaboticabal, in collaboration with the Brazilian Agricultural Research Corporation (EMBRAPA), has developed an artificial intelligence (AI) tool to assess the stress levels of tambaqui (Colossoma macropomum), the most widely produced native fish in Brazil. The study was published in the journal Aquaculture. The results could impact both animal welfare and the selection of specimens that [...]ver notícia -
Deforestation reduces rainfall by 74% and increases temperatures by 16% in the Amazon during the dry season, study says
Publicado em 02 setembro 2025(Press-News.org) - Deforestation in the Brazilian Amazon is responsible for approximately 74.5% of the reduction in rainfall and 16.5% of the temperature increase in the biome during the dry season. For the first time, researchers have quantified the impact of vegetation loss and global climate change on the forest. A study led by scientists from the University of São Paulo (USP) in Brazil provides fundamental results to guide effective mitigation and adaptation strategies. These are [...]ver notícia -
Researchers use seaweed to manufacture raw materials for civil construction
Publicado em 28 agosto 2025(Press-News.org) - Brazilian researchers have developed a ceramic clay that is lighter than that normally used in civil construction by adding algae from the Sargassum genus to the manufacturing process. These brown algae, also known as sargassum, are common in the central Atlantic Ocean. However, they have been washing up in large quantities on beaches in the Caribbean, the United States, and northern Brazil, where they have become problematic. Their accumulation on beaches can harm human [...]ver notícia -
For students with severe attention difficulties, changing school shifts is not the solution
Publicado em 26 agosto 2025(Press-News.org) - Several studies have shown that students who attend afternoon classes tend to perform better in school than those who attend morning classes. This is due to greater synchrony between class times and students’ biological clocks. However, a study of children and adolescents revealed that this does not apply to students with attention deficit hyperactivity disorder (ADHD) or symptoms of the condition. For this group, changing school shifts does not significantly improve [...]ver notícia -

Study shows ways to tackle homophobic bullying in schools
Publicado em 12 junho 2025(Press-News.org) - Showing students audiovisual narratives that simulate homophobic bullying scenarios in schools can capture their attention and generate reflection on social prejudices, promoting respect and inclusion. This strategy is presented in an article published in the Journal of School Violence. In the study, supported by FAPESP, researchers from São Paulo State University (UNESP) in Brazil investigated the extent to which this type of tool can serve as an instrument for [...]ver notícia -
Research expands options for more sustainable soybean production
Publicado em 17 abril 2025(Press-News.org) Brazil is the world’s largest producer of soybeans and one of the reasons is the incorporation of bio-inputs, microorganisms that promote biological nitrogen fixation. Without this practice, this essential nutrient would have to be supplemented with fertilizer. By managing fertilizer use, Brazilian growers can save an estimated USD 15 billion per year. The main bio-input used commercially today is bacteria of the genus Bradyrhizobium spp. (rhizobia). In a study [...]ver notícia -
Study details role of protein that may play a key role in the development of schizophrenia
Publicado em 17 abril 2025(Press-News.org) Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative diseases and mental disorders such as multiple sclerosis and schizophrenia. The findings pave the way for new research and potential treatments. Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of [...]ver notícia -
Studies evaluate the health effects of bioactive compounds obtained from plants
Publicado em(Press-News.org) Fruits and plant extracts contain bioactive compounds that can help treat or prevent diseases. To characterize and understand their mechanism of action, researchers from universities and research institutions in Brazil and Germany have conducted independent but complementary studies. Some of the results were presented at a lecture session on the future of food and nutrition research on March 25th during FAPESP Week Germany at the Free University of Berlin. According to [...]ver notícia
