People with diabetes who have had COVID-19 tend to recover more slowly, experience more long COVID complications, have a poorer quality of life, and require closer and more prolonged monitoring by medical teams. This was demonstrated in a study by the University of São Paulo, which involved 870 individuals followed for up to seven months after hospitalization. The study is published in the journal Scientific Reports. "Diabetes isn't only a risk factor for the acute phase of COVID-19. [...]

The Oropouche virus outbreak in 2023 drew attention in Brazil and other Latin American countries not only because of its scale—with more than 30,000 cases recorded nationwide—but also because of the first confirmed death in the country caused by the disease and its rapid spread to all states, extending beyond the Amazon region. In light of this situation, the World Health Organization (WHO) expressed concern earlier this year and called for the accelerated development of prevention and [...]

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have identified a molecule on the surface of cells that could be a promising therapeutic target against cancer. This molecule plays an important role in tumor progression by regulating cellular behavior. The research is published in the journal Cytotechnology. The work showed that overexpression of the syndecan-4 (SDC4) receptor provides tumor cells with a protective shield. In a laboratory experiment, the researchers [...]

The presence of minerals in oilseeds, such as Brazil nuts (Bertholletia excelsa) and cashews (Anacardium occidentale), does not guarantee that the body will use them. A study conducted at the Diadema campus of the Federal University of São Paulo (UNIFESP) in Brazil and published in the journal Química Nova evaluated the bioavailability of these nutrients. Bioavailability is defined as the fraction of the mineral actually released during simulated gastrointestinal digestion and potentially [...]

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered a new strategy that may protect neurons and other brain cells involved in Parkinson's disease in the future. The results of the study, which was conducted in mice, were published in the journal Neuropharmacology. The study evaluated the effect of a peptide (Ac2-26)—a fragment of a protein (Annexin A1)—on the disease. This protein is produced naturally in both rodents and humans, and previous [...]

Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research in Bacterial and Bacteriophage Biology (B3 RIDC) and was published in the journal PLOS Biology. It shows that these substances primarily act in competition among microorganisms for space and resources. The study also suggests that these substances may inspire the [...]

The Brazilian Amazon may be approaching a critical threshold earlier than scientists once expected, with a lengthening dry season raising fresh concerns about the stability of one of the world's most important ecosystems. What's happening? Reddit users recently discussed research summarized by Agência FAPESP, indicating that the Brazilian Amazon is beginning to experience conditions scientists had expected to occur much later. According to the summary shared in a post in the [...]

Dry season expands: The Brazilian Amazon’s dry season now lasts about six months, surpassing earlier predictions and raising concerns over forest stability. Global loss warning: A UN report finds the world lost over 40 million hectares of forest from 2015 to 2025, with restoration progress far too slow. Local solutions rising: Community-led conservation in Ghana and Guyana shows how forest protection can deliver both climate benefits and improved livelihoods. Amazon dry season now [...]

Box jellyfish are often feared as dangerous animals, with some species capable of causing severe or even fatal stings. However, box jellyfish nematocysts—organelles responsible for this toxic sting—are theorized to also play an unexpected role in reproduction. While many studies focus on researching the range of toxicity levels exhibited by the more than 50 species of box jellyfish, their reproductive process is poorly understood. Global study of jellyfish reproduction In a new study, [...]
